专利摘要:
The coupling part, in particular a cutting head (6) for a drilling tool, for replaceable mounting in a coupling bracket (10) has a coupling pin (8) which is surrounded by a support surface (16) present on the cutting head, the coupling pin (8) having several types of functional surfaces (20, 22), i.e. abutment surfaces (22) for transmitting a torque between the cutting head (6) and the carrier (4), and clamping surfaces (20) for centering and clamping the cutting head (6) in the coupling bracket (10). The coupling pin (8) has an axial front pin area (30) and a connecting, axial rear pin area (32), the clamping surfaces (20) and the abutment surfaces (22) being arranged in different pin areas (30, 32). This insulation and distribution of the functional surfaces (20, 22) to the different pin areas (30, 32) enables a simplified production of the coupling pin (8) and a more robust configuration as a whole.

202530In addition to this enclosed type of coupling, couplings are also known forwhich the enclosed coupling pin carries exclusively the clamping surfaces, but therethe abutment surfaces, on the other hand, project in the radial direction, during the design of aledge, the abutment surfaces reaching all the way to the outer circumferential surface. Such a notenclosed coupling is described, for example, in US 2011/0318128 A1 and in US 6,059492. Said document also describes a zinc joint configuration for the clamping surfaces,said clamping surfaces forming an undercut to ensure protection againstaxial extension.
In applicant's DE 10 2012 200 690.7, which was not published at the date ofsubmission, a coupling of the enclosed coupling type is described, in respect of whichthe coupling pin, viewed in cross section, has an approximately rectangular basic shape andintersected by chip spaces. The transverse portions of the coupling pin thereby formthe clamping portions while the longitudinal portions of the coupling pin form the abutment surfaces.
At the same time, the coupling pin has a generally approximately zinc joint design.
The connection point is in the form of a self-centering and self-clamping,reversible interchangeable coupling. No additional fasteners, such as screwsor the like, are provided to secure the cutting head in the carrier.
Due to the zinc joint design of the coupling pin and the different functional zonesis the manufacture of a coupling pin of this type is associated with a certaincost. At the transition between the coupling pin and the flat support surface onthe cutting head also has an acute angle due to the zinc joint design,and this leads to high stress concentration forces, especially in the areaaround the abutment surfaces.
Field of the inventionBased on this, the present invention is based on the object ofallow and a particularly self-clamping, reversibly releasable coupling betweentwo coupling parts, in particular a cutting head for a drilling tool and one with2025303the cutting head conforming carrier, which coupling is suitable for receivinghigh forces and which from an engineering point of view is easy to manufacture.
Solution to achieve the purposeThe object is achieved according to the invention by using a cutting head with theprepared the features of claim 1.
The connection point here is generally constructed according to the technique of the enclosurethe type of coupling, ie. it has a coupling pin which is surrounded by an iin particular flat, support surface arranged on the cutting head. The coupling part is preferablya cutting head for a modular rotary tool, in particular a drilling tool. INmounted condition, the coupling pin engages in a coupling bracket of an additional onecoupling part, in particular a carrier for the modular rotary tool. INIn the following text, the first coupling part has generally been referred to as "cutting head" andthe additional coupling part has generally been referred to as "carrier". Basically it isreverse configuration also possible. The configuration of the coupling is thennot limited to use for a connection between a cutting head and acarrier for a rotating tool.
The coupling pin has several types of functional surfaces, ie. stop surfaces for transfera torque and clamping surfaces for centering the coupling part in the coupling bracket.
Viewed in the axial or longitudinal direction, the coupling pin as such is theredivided into two tap areas, ie. in an axially forward pin area that is orientedtowards the end side of the cutting head and a rear pin area oriented towardsthe carrier. The clamping surfaces and the abutment surfaces are then arranged in different tapping areas,i.e. axially displaced relative to each other.
By the measure to insulate the various functional surfaces in the longitudinal direction in questionif a uniform, enclosed coupling pin, an individual adaptation ofthe different tapping areas at different axial heights to the respective requirements. Thisallows a simplified production, as the production per tap area mustdesigned optimized exclusively for a specific functional area. Thanks to the insulation can2025304in addition, the critical transition area between the support surface of the cutting head andthe coupling pin is also configured in a freer way. Specifically, in oneprotection against axial extension by means of inclined surfaces that form aundercut, the critical transition area to the support surface is neutralizedthe cutting head because the functional surfaces are axially insulated.
Generally, said coupling is a self-centering coupling which isself-clamping in the axial direction and which can be connected or detached again,preferably without tools. For this purpose, the cutting head is typically inserted inthe coupling bracket in the axial direction and is then brought to the end position by turningaround.
For a reliable self-clamping configuration, the clamping surfaces are suitableconfigured as a zinc joint to protect against axial extension. Furtherclamping or fastening elements, such as screws, etc., can preferably be considered asredundant.
The different types of functional surfaces, ie. the clamping surfaces and the abutment surfaces arepreferably in each case arranged the rotational displacement relative toeach other. In addition or as an alternative, the function surfaces are of the same typearranged in each case arranged in pairs and opposite to each other, inin particular rotationally symmetrical by 180 °.
It has at least one pin area and in particular the entire coupling pinpreferably a rectangular shape, viewed in cross section. In this context, onesome deviation from the strict rectangular shape is also allowed about the basic shapeis rectangular, ie. the individual parties can thus have a curvature that isadapted to the radius. The concept of rectangular basic shape also includes a variantwhere an approximately rectangular base surface has recesses, for example as a result ofchip spaces. As a whole, the coupling pin therefore has a basic shape such asalso described in DE 10 2012 200 690.7. Using the coupling pinapproximately rectangular basic shape achieves good self-centering and self-squeezing andat the same time good transmission of torque.202530At least one of the tap areas, preferably both tap areas and thus the wholethe coupling pin, has in each case in pairs opposite each otherlongitudinal portions and opposite transverse portions, whichmerge into each other in particular via rounded transition portions. The function surfaces arethereby formed on the longitudinal portions and the transverse portions. Thethe transverse portions and the longitudinal portions are then oriented in particularat least approximately at right angles to each other.
The longitudinal portions and the transverse portions are suitably alsointerrupted by chip spaces, so that the transverse portions and the longitudinal onesthe batches in each case run out towards a respective chip space. The chip spacesthus cut out sub-areas in the approximately diagonally opposite corner areas ofthe approximately rectangular base surface.
Preferably, the longitudinal portions of one pin area formthe abutment surfaces, while the transverse portions of the second pin area formthe clamping surfaces. Thanks to this configuration, an approximately diagonal is formed as a wholestaggered arrangement of the functional surfaces in relation to each other.
The functional surfaces are thus at a distance in relation to each other both incircumferential direction (direction of rotation or direction of rotation) and in the axial direction. Onthis way can in principle be a rectangular basic shape for the entire coupling pinconfigured at the same time as insulation of the functional surfaces is achieved. Through itapproximately the rectangular basic shape of the entire coupling pin will cometransverse portion of the second pin area to connect to it in the axial directionthe transverse portion of the first pin area, and the longitudinal portion thereofthe second pin area will connect in the axial direction to the longitudinal portionfor the first pin area, and the longitudinal portions and the transverse onesthe portions in the two tap areas are therefore in each case designed with the samerotation angle position and are in this respect aligned with each other.
According to a suitable development, the longitudinal parts will come for onethe pin area in which the clamping surfaces are designed, and / or the transverse portions for202530the second pin area, in which the abutment surfaces are formed, in each case to formfree surfaces without function. The respective tapping areas therefore have only one type offunctional surfaces, namely either clamping surfaces or abutment surfaces. The other surface ineach case is then inactive and forms the free surface. This is clearthat when the cutting head is inserted into the carrier, these surfaces will not interact witha corresponding complementary surface of the carrier, i.e. they are at a distance fromthe carrier and forms a free space towards it. This ensures that the respectivethe function surfaces interact in a defined way with the assigned onecomplementary functional surface on the carrier and that no over-regulation occurs.
The two pin areas are preferably directly adjacent to each other in axialdirection, that is, the longitudinal and transverse portions are directadjacent to each other. This enables a compact configuration as a whole.
According to a preferred development, the respective parties are for the adjoiningthe pin areas then oriented at an angle to each other viewed in a plane which isparallel to the longitudinal direction and are in each case separated fromeach other through a separation line or a breaking line with in particular horizontalextent. In the area of the separation line, a radius is usually formed.
The line of separation between the longitudinal portions then has an axialdisplacement relative to the line of separation between the transverse portions. Thepreviously described dysfunctional free surfaces are formed during manufacturepreferably by grinding the respective surfaces, which leads just todisplacement of the separation line. The displacement is therefore only insignificant andcaused by said grinding. The tapping areas are therefore sanded as a whole on differentway.
At least one of the parties and preferably both the transversal parties and thosethe longitudinal portions of the two tapping areas are arranged in each casewith an obtuse angle relative to each other. The parties are here oriented inin relation to each other in particular with an outer angle in the range from approx130 ° to 160 °. Through the configuration with obtuse angle is therefore bothclamping surfaces and abutment surfaces - viewed in cross-section in the longitudinal direction -2025307preferably oriented at an angle to the longitudinal or axial directionthe direction. Regarding the clamping surfaces, said angular orientation is providedthe undercut of the protection against axial extension (zinc joint).
As an alternative to the roof angle, there is in principle the possibility of only the clamping surfacesare inclined in relation to the longitudinal axis and that the abutment surfaces areoriented parallel to the longitudinal axis.
The obtuse angle configuration is a preferred embodiment variant. Boththe tapping areas are here preferably arranged obliquely and asymmetrically inrelation to the longitudinal axis, the abutment surfaces in particular beingoriented with greater inclination relative to the longitudinal axis.
In principle, there is the possibility of designing either the clamping surfaces or the abutment surfaces in itfront tap area. If it is a configuration with abutment surfaces in itrear pin area, the abutment surfaces are insulated from the support surface of the cutting head, andtherefore, there is no direct connection to the support surface of the cutting head in the area of thegreatest torque forces. Due to the zinc joint configuration of the clamping surfaceshowever, even now at the same time an acute angle to the support surface of the cutting head is formed.
This maintains a certain concentration of voltage, even if none is excessivestrong forces (torque) are transmitted at this point of the clamping surfaces.
According to a preferred configuration, however, the abutment surfaces are arranged thereonfront pin area while the clamping surfaces are arranged on the rear pin area.
In addition to the blunt angle orientation, this leads to a blunt angletransition angle between the coupling pin and the support surface of the cutting head, and thereforehardly any voltage concentration forces will appear in thiscritical transition area.
In general, therefore, it is generally assumed that the functional surfaces adjacent to the support surface onthe cutting head forms an obtuse angle therewith, said obtuse anglepreferably greater than 100 °, in particular greater than 110 ° or even 120 °up to a maximum of about 130 °.202530As an alternative to the basic output configuration, in which theythe respective portions in the tap areas in each case are directly adjacent toin the axial direction, are formed according to an alternative preferred embodiment, aledge-like transition between the two tap areas in the surrounding areathe impact surfaces. This thus means that the abutment surface in one tap area does notpasses directly into the corresponding longitudinal portion in the second pin area. Rathera ledge is formed here with a particularly horizontal extent.
At the same time, the clamping surface suitably extends in the circumferential direction over the entire pin area.
Through this configuration, especially in combination with the ledge is achievedtherefore the special advantage of achieving such a comprehensive envelope aspossible of the clamping surface for the cutting head to be clamped in the carrier in a reliable mannerway. The clamping surface is then typically oriented at least substantially concentrically inrelation to the circumferential surface of the cutting head resp. the carrier and is therefore only into a limited extent suitable for the transmission of torque forces. Throughthe design of the ledge in the area around the abutment surfaces, there is therefore oneadvantageous possibility to allow the abutment surface to break off from the circumferential direction, so thatthe abutment surface is oriented at an angle, preferably at right angles to the circumferential direction, forto provide a torque transmission that is as efficient as possible.
Furthermore, the object according to the invention is achieved by means of a modular rotationtools, in particular a drilling tool, with the developed features of claim 14. Theyadvantages and preferred embodiments described with respect tothe coupling part, in particular the cutting head, can conveniently be transferred to the rotating onethe tool. The latter is generally formed by the cutting head and a carrier in whichthe cutting head can be inserted in a reversibly replaceable manner. The carrier then has onecoupling bracket that has functional surfaces that are complementary tothe coupling pin of the cutting head.
By complementary functional surfaces is meant surfaces which with respect to theirgeometric configuration, interacts with the respective functional surfaces ofthe coupling pin for transmitting forces and which abuts two-dimensionally against2025309each other. Complementary free surfaces are designed solely with respect to thosethe free surfaces of the coupling pin, said complementary free surfaces being mountedcondition exists at a distance from the free surfaces, forming a freespace, and are only arranged opposite each other but do not interact witheach other in the sense that they can transmit forces.
To achieve reliable clamping of the cutting head, the clamping surfaces are onthe coupling pin suitably alternatively designed with a certain excessive dimensionand / or exhibits an eccentricity or an elliptical configuration such thatthe clamping force increases with increasing torque on the cutting head inthe coupling bracket.

Description of embodimentsIn the figures, parts that function in the same way in each of the cases have been describedwith the same reference numerals.
The drilling tool according to all three embodiment variants is designed as onemodular drilling tool with a carrier 4 and a cutting head 6 that can be attached to onereversibly interchangeable manner in said carrier. The coupling between the carrier 4 andthe cutting head 6 then takes place by means of the so-called enclosed type ofcoupling. For this purpose, the cutting head 6, at its rear end, has onecoupling pin 8 which extends in axial or longitudinal direction and which canis inserted into a coupling bracket 10 for the carrier 4. The coupling bracket 10 is here formed inboth sides by means of two edge webs 12 extending in axial direction, as onecontinuation on a respective drill carrier. Said edge life is interrupted bychip spaces 14. The edge web 12 completely encloses the coupling pin 8except for the interruption created by the chip spaces 14.20253011The chip spaces 14 are also led further into the cutting head 6 and thereby cut out a pieceof the coupling pin 8. The coupling pin 8 is enclosed by a plane, on the cutting headarranged support surface 16 which extends in a horizontal plane and which is interruptedonly of the chip spaces 14. The coupling pin 8 is in the direction of the carrier 4connected to by an insertion pin 18 which is designed centrally and concentrically inrelation to a central axis, which is at the same time the longitudinal axis.
Preferably no jamming occurs at all and neither does anycentering at the insertion stage. These functions are performed exclusively viathe functional surfaces (which are explained further later) on the coupling pin 8,namely the clamping surfaces 20. As further functional surfaces, the coupling pin 8 hasabutment surfaces 22 for transmitting torque. In the one given as an exampleIn this embodiment, the drilling tool further has coolant channels 24 whichappears at the base of the coupling bracket 10 and which then continues inthe coupling pin 8 to the front front side of the cutting head 6 and emergeswhere.
In the assembled state, the cutting head 6 rests flat with it on the cutting headpresent support surface 16 on the front support surfaces 26 on the edge web 12.
The cutting head 6 is generally installed by inserting the cutting head 6 at onerotational position which is offset in relation to the position of the fixed onethe end position. Then turn the cutting head so that the correspondingfunctional surfaces are mutually engaged with the complementary functional surfacesof the coupling bracket 10 to ensure the desired self-centering, self-centeringclamping and carrying torque.
As shown in particular in the respective side views of the cutting heads 6 and inillustrations of the cross sections, the coupling pin 8 is as suchsubdivided into a front pin area 30 and a rear pin area 32 whichpreferably connect directly to each other in the axial direction. As can be seen inin particular in the horizontal projections of the cutting head 6 and of the carrier, havethe coupling pin 8 and the coupling bracket 10, which is designed in a complementary manner inrelation to the coupling pin, an approximately rectangular basic shape and20253012the coupling pin 8 therefore has longitudinal portions 34 and transverse portions 36,which continuously merge into each other via transition portions 38 which are designed asrounded corners.
According to the first two variants of embodiments, the entire coupling pin 8 andtherefore, both the front pin area 30 and the rear pin area 32 are formedwith a substantially rectangular basic shape. The transverse portions 36 forthe pin areas 30, 32 which are axially connected to each other are arranged witheach other and therefore cover the same angle of rotation. The same goes for themlongitudinal portions 34. In this case, it is of particular importance that the respectivethe pin areas 30, 32 have either exclusively clamping surfaces 20 or exclusivelyabutment surfaces 22. According to the first two embodiments, the two functional surfaces arein each case arranged offset relative to each other in the circumferential direction,and thus the functional surfaces as a whole are arranged approximately diagonally inrelationship to each other.
In general, the abutment surfaces 22 are then formed on the longitudinal portions 34while the clamping surfaces 20 are formed on the transverse portions 36.
According to all variants of embodiments, the clamping surfaces 20 are designed assloping, sloping surfaces in the same way as a zinc joint, to form aundercut.
In view of a simplified manufacturing process, the surfaces, in particularthe clamping surfaces 20, formed along a circular path so that they are easily accessibleproduce using grinding technology.
Due to the undercuts formed by the zinc joint configuration, they areindividual function surfaces 20, 22 are often impossible to see or difficult to see inhorizontal projection illustrations of the carrier 4 (Figure 3, Figure 8, Figure 13). The surfacesof the coupling bracket 10 which are complementary to the surfaces of the coupling pin 8are generally provided with the same reference numerals, with the addition of the letter A.
The clamping surfaces of the coupling bracket 10 which are complementary to the clamping surfaces 20 of20253013the coupling pin 8 has therefore been assigned the reference numeral 20A, the complementary onesabutment surfaces 22A, etc.
According to the first two variants of embodiments, the free surfaces 40 connect ineach case in the axial direction to the respective functional surfaces 20, 22, the free onesthe surfaces are dysfunctional in the sense that they do not contribute to the transfer oftorque or for centering or clamping. The free surfaces 40 are therefore alsoin each case arranged diagonally opposite each other. Both between the freethe surfaces 40 which between the functional surfaces 20, 22, are surface portions in each case formedin the circumferential direction, via the transition portions 38.
More specifically, the free surfaces 40 are formed by a separate grinding process.
In this way, a crack line or separation line 41 is displaced so that aseparation lines 41 between the front and rear pin areas 30, 32 in the areafor the longitudinal portions 34 resp. the transverse portions 36 are provideddisplaced relative to each other in the axial direction. The separating lines 41extends in each case in a horizontal direction (compare here in particularFigures 2B and 7B).
As can also be observed in particular in the illustrations of cross sections for the firstboth variants, the free surfaces 40 are spaced apart from the complementary onesfree surfaces 40a of the coupling bracket 10, and therefore have a part with afree space. In all embodiments, the individual surfaces merge into each other,viewed in the axial direction, in each case via roundings or chamfers 44.
In addition, a chamfer 44 which is designed as a free space is formed onthe end face of the coupling pin 8 and the front side of the carrier 6.
As specifically described in the respective illustrations of cross sections, they arerespectively, the pin areas 30, 32 arranged at an obtuse angle in relationto each other and enclose an obtuse angle oi ° of about 150 ° in the regionin between (cf. Figures 4B and 9C). Since the clamping surfaces 20 in each case havea zinc joint design, said clamping surfaces each have an inclination angle ß1 irelative to the longitudinal axis to form an undercut. Due20253014the blunt angle configuration is the kink angle between the two pin areas30, 32 in part constructed in a manner involving a contraction of 8(embodiment variant 1, figures 2B, 4B, 5B) and partly in a manner which involves aoutward arching in the case of the second embodiment variant (Figures 7B, 9C,10B).
The significant difference between the two first embodiments can be observed inthe arrangement of the function surfaces 20, 22. According to the first embodiment variantas shown in Figures 1 to 5, the abutment surfaces 22 are formed on the front pin areaWhile the clamping surfaces 20 are formed on the rear pin area 32. In contrast, inIn the case of the second embodiment variant according to Figures 6 to 10, the clamping surfaces 20formed on the front pin area 30 while the abutment surfaces 22 are formed onthe rear pin area 32.
The clamping surfaces 20 are oriented with the angle of inclination ß1 relative to itthe longitudinal axis and the abutment surfaces 22 are oriented at an angle of inclination ß2.
In this case, ß1 is usually smaller than the angle ß2, and therefore a certain asymmetry arises.
More specifically, ß1 is about 10 ° while ß2 is about 20 °, ie. about twice as muchBig.
When arranging the abutment surfaces 22 in the front pin area 30 withthe angle of inclination ß2, as a whole a blunt transition angle to the support surface ofthe cutting head 16, said transition angle being approximately in the area around110 ° (cf. for this example Figure 4B).
The third embodiment variant (Figures 11 to 14) differs from the twoprevious embodiments in that only one of the two pin areas 30,32, i.e. the rear pin area 32 in the exemplary embodiment,has a substantially rectangular basic shape. On said pin area 32, isthe abutment surfaces 22 again formed on the corresponding longitudinal portions34. In the second tap area, i.e. on the front pin area 30, in thatexemplary embodiment, on the other hand, a continuous clamping surface 20 is formedas a zinc joint, said clamping surface extending at least approximately15concentric with the circumferential line of the cutting head 6 and thus of adrill carriers, as can in particular also be observed in Figures 11 and 12. Thisdifferent geometries of the two pin areas 30, 32 provide oncorrespondingly also a ledge-like transition from the pin area 30 to itrear pin area 32 in the area of the abutment surface 22. At this point hasthe coupling pin 8 therefore a ledge 42 with a particularly horizontal extent.
The basic shape of the front pin area 30 is approximately circular (with the recessesas a result of the chip spaces 14) resp. slightly elliptical. Through this actionan extra large enclosure is achieved in the area of the clamping surfaces 22, by means ofedge web 12 and thus a reliable self-clamping is achieved.
