    SUMMARY OF THE INVENTION According to the present invention, said object is achieved by means of a processing unit having the features defined in claim 1.
    The processing unit according to the invention comprises: - a drive unit with a drive motor and a drive means rotatable by the drive motor, which is rotatably arranged in a housing of the drive unit, and - a transfer unit attached or attachable to the drive unit, which comprises: o a housing, o a first rotatable member configured for connection to said drive means of the drive unit for rotation therewith, said first rotatable member being rotatably mounted in the housing and rotatable about a first axis of rotation, and a second rotatable member configured for connection to a machining tool, said second rotatable means is rotatably mounted in the housing and rotatable about a second axis of rotation extending parallel to and spaced from the first axis of rotation, and a transmission mechanism provided in the housing for transmitting torque from the first rotatable member to the second rotatable member, wherein the second rotatable member via said drive means, the first root The operable member and the transmission mechanism are rotatable under the action of the drive motor. The transfer unit is adjustable in different rotational positions relative to the drive unit by rotating the transfer unit housing relative to the drive unit housing about an axis of rotation coinciding with said first axis of rotation, and the processing unit comprises locking means for locking the transfer unit housing to the drive unit housing. By turning the transfer unit relative to the drive unit, it becomes possible to easily and quickly adjust the lateral position of, for example, a machining tool in the form of a drilling tool relative to the object to be drilled before drilling begins, without the drive unit or the tripods that support this need to be moved. In addition, in the case where the drive unit is displaceable along a pillar, when drilling by means of a drilling tool attached to the second rotatable member, it becomes possible to reduce the distance between the pillar and the centerline of the drilling tool by placing the transfer unit in a rotational position with the drilling tool possible. The shorter the distance between the center line of the drilling tool and the column, the less the column tends to bend backwards away from the drilling tool when the drilling pressure is applied. A reduced deflection of the column leads to the drilling tool being moved straighter into the borehole, which reduces the friction between the drilling tool's mantle surface and the borehole wall and thereby results in a faster and less energy-intensive drilling process.
    According to an embodiment of the invention, the transmission mechanism comprises a first gear which is rotatably connected to the first rotatable member and a second gear which is rotatably connected to the second rotatable member, the first gear, directly or via one or more intermediate gears, being in driving engagement with the second gear so that the second rotatable member via these gears is caused to rotate about the second axis of rotation during a rotation of the first rotatable member about the first axis of rotation. By suitable design of the gears of the transmission mechanism, the gear ratio between the first rotatable member and the second rotatable member and thereby the speed of the second rotatable member can be adjusted as needed.
    Another embodiment of the invention is characterized by: - said reading means comprises a clamping ring which is rotatably arranged in the housing of the drive unit around said drive means, and two or more screw means cooperating with the clamping ring, wherein respective respective screw means via screw threads and the connecting means extending through the housing of the transfer unit are connected to the clamp, - that the clamping ring has a shoulder which abuts against a corresponding shoulder of the housing of the drive unit and thereby prevents an axial displacement of the clamp ring towards the transfer unit, - that the transfer member h has a support surface, via which the housing is arranged to abut against a corresponding support surface of the drive housing, and - said screw means are arranged on either side of the first rotatable member and arranged to press the housing of the transfer unit in the direction of the clamping ring so that said support surfaces are pressed against each other to mutually locking engagement and thereby reads the housing of the transfer unit to the housing of the drive unit in the current rotational position.
    This makes it possible to quickly and easily read the housing of the transfer unit to the housing of the drive unit in the desired rotational position.
    Another embodiment of the invention is characterized by: - that the drive unit has a fluid channel which is connected to a fluid channel extending through the clamping ring, - that the transfer unit has a fluid channel extending through it, and - that said fluid channel of the clamping ring is connected to said fluid channel at the transfer unit via a connecting means extending between the clamping ring and the housing of the transfer unit when the transfer unit is attached to the drive unit.
    Because the connecting means extends between the clamping ring and the housing of the transfer unit, the connecting means will accompany the clamping ring when it together with the housing of the transfer unit is rotated about said axis of rotation, whereby said fluid channels can be maintained connected to each other via the connecting means.
    This makes it possible to supply flushing liquid to a machining tool attached to the transfer unit via these fluid channels, independently of the rotational position of the transfer unit relative to the drive unit.
    According to another embodiment of the invention, the transfer unit is releasably connectable to the drive unit. As a result, a transfer unit coupled to the drive unit can, if necessary, be replaced by another transfer unit.
    According to another embodiment of the invention, the processing unit comprises two or more such transfer units which can be releasably coupled to the drive unit with different distances between the first axis of rotation and the second axis of rotation and / or with different gear ratios of the transfer mechanism. In this way, the processing unit can be adapted in a simple and fast manner depending on the processing tool to be used by replacing the transfer unit. For example, a transfer unit with a longer distance between the axes of rotation and a lower gear ratio of the transfer mechanism can be selected when drilling is to take place with a drilling tool of relatively large diameter, while a transfer unit with a shorter distance between the axes of rotation and a higher gear ratio of the transfer mechanism can be selected when drilling is to take place with a drilling tool with a relatively small diameter.
    Other advantageous features of the processing unit according to the invention appear from the dependent claims and the following description.

    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Fig. 1 shows a machining assembly 1 according to an embodiment of the present invention. This machining unit 1 comprises a drive unit 2 with a drive motor and a drive means 3 rotatable by the drive motor (see Figs. 3, 4 and 6). The drive means 3 is rotatably arranged in a housing 6 of the drive unit 2. A transfer unit 4 is attached to the drive unit 2. This transfer unit 4 is arranged to transmit torque from said drive means 3 of the drive unit to a machining tool 5 attached to the transfer unit, which in the illustrated example is of a drilling tool in the form of a cylindrical drill bit which at its outer annular edge is provided with machining bodies 7 where diamonds form the cutting edges. This drilling tool is intended for drilling holes in concrete or other hard materials. The machining tool 5 is releasably attached to the transfer unit 4 and also other types of drilling tools than those illustrated here or machining tools for other types of machining are hole making can be attached to the transfer unit 4.
    In the illustrated embodiment, the processing unit 1 is provided with a stand 8, which comprises a support plate 9, via which the stand is intended to rest against a support surface, and an elongate pillar 10 attached to the support plate 9 and projecting therefrom.
    The column 10 is advantageously rotatably mounted to the support plate 9 to allow an adjustment of the inclination of the column relative to the support plate. A rack 11 extends along the column 10. In the illustrated example, this rack 11 is formed by two opposed racks 12a, 12b which are arranged parallel to and spaced apart from each other. The drive unit 2 is connected to a feed device 13, which is provided with a rotatable feed gear 14 (see Fig. 2) which is designed for engagement with said gear path 11. The feed device 13 is further provided with operating means 15, by means of which the feed gear 14 is rotatable for displacement of the feed device 13 and the drive unit 2 along the column 10. Said operating means 15 may comprise a feed motor for driving the feed gear 14, but may also be designed for manual driving of the feed gear 14. In the illustrated embodiment, the feed device 13 is fixedly connected to drive unit 2, but the feed device and drive unit could alternatively constitute separate and interconnectable modules.
    Rotatably mounted guide wheels 16 are attached to the drive unit 2 and / or the feeding device 13. These guide wheels 16 are in engagement with guide grooves 17 on the pillar 10 and are arranged to hold the drive unit 2 and the feeding device 13 in place by the pillar. In the illustrated embodiment, the machining tool 5 is attached to the transfer unit 4 via a tool adapter 18, which is releasably attached to the transfer unit 4 and which is provided with a thread 19 designed for engagement with a corresponding thread of the machining tool 5. The transfer unit 4 has an outer casing 20. A first rotatable member 21 (see Figs. 4 and 6), which is designed for connection to said drive means 3 of the drive unit 2 for rotation therefrom, is rotatably mounted in the casing via suitable bearings 22. And rotatable about a first axis of rotation A1. A second rotatable member 23 (see Figs. 2 and 4), which is designed for connection to a machining tool 5, is rotatably mounted in the housing 20 via suitable bearings 24 and rotatable about a second axis of rotation A2 which extends parallel to and at a distance from the first axis of rotation A1.
    Said axes of rotation A1, A2 are thus offset in parallel in relation to each other. The first rotatable member 21 is accessible from the side of the housing 20 facing the transfer unit 4 and the second rotatable member 23 is accessible from the opposite side of the housing 20. The second rotatable member 23 constitutes a so-called spindle and via a suitable coupling device 25, a tool adapter 18 can be coupled to this spindle. In the following, the term spider is used to refer to this rotatable member 23.
    A transmission mechanism 26 (see Fig. 4) is arranged in the housing 20 for transmitting torque from the first rotatable member 21 to the spindle 23. Via said drive means 3, the first rotatable member 21 and the transmission mechanism 26, the spindle 23 is thus rotatable under the action of drive motor of the drive. The transmission unit 4 is adjustable in different rotational positions relative to the drive unit 2 by rotating the housing 20 of the transmission unit relative to the housing 6 of the drive unit about an axis of rotation which coincides with said first axis of rotation A1. The transfer unit 4 is thus rotatably attached to the drive unit 2 in such a way that the housing 20 of the transfer unit, while the transfer unit 4 remains coupled to the drive unit 2, can be rotated relative to the housing 6 of the drive unit about said axis of rotation. This axis of rotation extends parallel to the longitudinal axis of the column 10 when the drive unit 2 is connected to the column via the feeding device 13. The processing unit 1 comprises locking means 40 for locking the housing 20 of the transfer unit to the housing 6 of the drive unit in the desired rotational position relative thereto.
    In the illustrated embodiment, the transmission mechanism 26 comprises a first gear 27 which is rotatably connected to the first rotatable member 21 and a second gear 28 which is rotatably connected to the spindle 23. The first gear 27 and the first rotatable member 21 are suitably formed in one piece, and the second gear 28 and the spindle 23 are suitably formed in one piece. In the example illustrated in Fig. 4, the first gear 27 is in direct engagement with the second gear 28 so that the spindle 23 via these gears 27, 28 is caused to rotate about the second axis of rotation A2 during a rotation of the first rotatable member 21 about the first axis of rotation A1. The first gear 27 could alternatively be in driving engagement with the second gear 28 via one or more intermediate gears.
    In the illustrated embodiment, the drive means 3 is constituted by a drive shaft projecting from the housing 6 of the drive unit, which is designed for engagement with an axial recess 29 of the first rotatable member 21. The drive means 3 is provided with external axial splines 30 designed for engagement with corresponding internal axial splines 31 in the recess 29 of the first rotatable member 21 for transmitting torque between the drive member and the first rotatable member. As an alternative, the drive means 3 could be provided with a recess for receiving a projecting shaft of the first rotatable member 21. As an alternative to axial splines, the drive means 3 and the recess 29 could have mutually complementary polygonal cross-sectional shapes, such as e.g. square or hexagonal cross-sectional shapes, for transmitting torque between the drive means and the first rotatable means. In the illustrated example, the drive means 3 is rotatably connected to a rotatable drive pulley 32, which is connected via a reducer gear (not shown) to the output shaft of the drive motor. A first cylindrical guide member 33 is attached to the housing 20 of the transfer unit and arranged coaxially with the first rotatable member 21, while a second cylindrical guide member 34 is attached to the drive unit 2 and arranged coaxially with the drive member 3. These guides the gears 33, 34 thus extend around the first axis of rotation A1.
    The control means 33, 34 are engaged with each other when the transfer unit 4 is attached to the drive unit 2 to together form a radial guide between the housing 20 of the transfer unit and the drive unit 2. These control means 33, 34 could alternatively be conical designed. In the illustrated embodiment, the first guide member 33 is constituted by a guide sleeve which is attached to a projection 35 of the housing of the transfer unit, while the second guide member 34 is constituted by a corresponding guide sleeve which is attached to the clamping ring 41 described below.
    In the illustrated embodiment, the above-mentioned locking means 40 comprises a clamping ring 41 (see Figs. 3, 4 and 6) which is rotatably arranged in the housing 6 of the drive unit around the drive means 3, and two screw means 42 cooperating with the clamping ring, which are arranged on either side of the first rotatable member 21. The drive member 3 extends through an opening in the center of the clamping ring 41.
    The clamping ring 41 has a conically shaped or flat shoulder 43 which abuts against a corresponding shoulder 44 of the drive housing 6 and thereby prevents an axial displacement of the clamping ring in the direction of the transfer unit 4. The respective screw means 42 are connected to the clamping ring 41 via separate threaded and extending through the housing 20 of the transfer unit 20 (see Fig. 6), which extends parallel to the first axis of rotation A1. In the illustrated example, the respective connecting means 45 are constituted by a pin screw which is clamped at its inner end to the clamping ring 41 and which at its outer end has an external thread 46. In this case the respective screw means 42 are constituted by a nut provided with an internal thread 47 designed for engagement with said external thread 46 of the connecting means 45. The respective screw means 42 are provided with a radially projecting flange 48, via which the screw means press against the housing 20 when a tightening of the screw means. 10 15 20 25 30 35 11 As an alternative, the respective screw means could consist of a screw with a screw head abutting against the housing 20 and a screw shaft extending through the housing, which at its end is provided with an external thread designed for engagement. with a corresponding internal thread of the clamping ring 41. In this case, the screw shaft thus forms the above-mentioned connecting means. The housing 20 of the transfer unit has a support surface 50, via which the housing 20 is arranged to abut against a corresponding support surface 51 of the housing 6 of the drive unit. These support surfaces 50, 51 can be conically shaped or flat. In the case where the support surfaces 50, 51 are conically shaped, the above-mentioned guide means 33, 34 could be dispensed with.
    In the illustrated embodiment, the latter support surface 51 is formed by a sliding ring 52 attached to the housing 6 of the drive unit. When the screw means 42 are tightened, the flanges 48 press the housing 20 of the transfer unit towards the clamping ring 41 so that said support surfaces 50, 51 are pressed against each other. to mutually locking frictional engagement and thereby lock the housing 20 of the transfer unit to the housing 6 of the drive unit in the current rotational position. By loosening the screw means 42, the locking friction engagement between the support surfaces 50, 51 is also loosened so that the housing 20 of the transfer unit becomes free to rotate relative to the housing 6 of the drive unit about the above-mentioned axis of rotation. Upon such rotation, the support surface 50 of the transfer unit slides against the support surface 51 of the drive unit and via the engagement of the connecting means 45 with the housing 20 of the transfer unit and the clamping ring 41 the clamping ring will be rotated relative to the housing 6 of the drive unit together with the transfer unit.
    In the illustrated embodiment, the drive unit 2 has a fluid channel 53 (see Fig. 4) which is connected to a fluid channel 54 extending through the clamping ring 41. The first-mentioned fluid channel 53 extends in a ring around the periphery of the clamping ring 41 so that it remains connected to the fluid channel 54 of the clamping ring when the clamping ring is rotated. The transfer unit 4 in turn has a fluid channel 55 extending therethrough which is connected to said fluid channel 54 of the clamping ring via a connecting means 56 extending between the clamping ring 10 and the transfer unit housing 20 when the transfer unit 4 is attached to the drive unit 2.
    Said connecting means 56 may for instance consist of a tube attached to the clamping ring 41 and projecting therefrom which is received in a recess 57 in the housing 20 of the transfer unit, as illustrated in Fig. 4. The fluid channel 55 of the transfer unit terminates with a tube 58 extending into the spindle 23 along the second axis of rotation A2. This tube 58 is designed for connection to a fluid channel 59 extending axially through the tool adapter 18. Via these fluid channels 53, 54, 55, 59, flushing fluid can be fed from the drive unit 2 to a machining tool 5 attached to the tool adapter 18 regardless of the rotational position of the transfer unit. active drive unit.
    As an alternative to the illustrated embodiment, the housing 20 of the transfer unit could be rotatably connected to the housing 6 of the drive via a cylindrical guide member which is rigidly connected to the housing 20 of the transfer unit and which is rotatably engaged with a corresponding cylindrical and rigidly connected to the housing 6 of the drive 6. control means, the former control means being lockable to the latter control means in the desired rotational position relative thereto by means of a suitable locking means.
    In the illustrated embodiment, the tool adapter 18 is attached to the spindle 23 by means of a coupling device 25 having an outer conical portion 60 of the tool adapter, which is designed to engage with a corresponding inner conical portion 61 of the spindle. Three locking balls 62 are radially displaceably received in respective radially through holes 63 of the inner conical portion 61. A locking sleeve 64 is rotatably arranged on the outside of the spindle 23 outside the locking balls 62.
    This locking sleeve 64 is rotatable back and forth between a locking position (see Figs. 4 and 5), in which the locking sleeve forces the respective locking ball 62 to assume an advanced position with the locking ball extending down into a groove 65 of the externally conical portion 60 while preventing of a mutual axial displacement between the tool adapter 18 and the spindle 23, and a disengagement position, in which the locking sleeve 64 allows the respective locking ball 62 to be displaced radially outwards to a retracted position while allowing a mutual axial displacement between the tool adapter 18 and the spindle 23. The spindle 23 further has an inner cylindrical portion 65 provided with inner axial splines 66, which are designed for engagement with outer axial splines 67 of an outer cylindrical portion 68 of the tool adapter 18 for transmitting torque between the spindle and the tool adapter. . As an alternative to axial splines, said portions 65, 68 could have mutually complementary polygonal cross-sectional shapes, such as for instance square or hexagonal cross-sectional shapes, for transmitting torque between the spindle and the tool adapter. The transfer unit 4 is suitably detachably interconnectable with the drive unit 2 so that a transfer unit attached to the drive unit can be replaced by another transfer unit if necessary. The processing unit 1 advantageously comprises two or more transfer units 4, 4 'which can be connected to the drive unit 2, with different distances between the first axis of rotation A1 and the second axis of rotation A2 and / or with different gear ratios of the transfer mechanism 26.
    In the illustrated embodiment, the transfer unit 4 can be disconnected from the drive unit 2 by unscrewing the screw means 42 from the connecting means 45, whereby the transfer unit becomes free to be pulled away from the drive unit in the axial direction of the connecting means. When a transfer unit 4 is to be displaced into engagement with the drive unit 2, the connecting means 45 act as guide pins for the transfer unit 4 while the transfer unit slides axially on the connecting means 45 via through guide holes 70 (see Fig. 6) of the transfer unit. Figs. 7a and 7b illustrate the drive unit 2 coupled to a transmission unit 4 'having a longer distance between the first axis of rotation A1 and the second axis of rotation A2 than the transmission unit 4 illustrated in Fig. 1. The transmission unit 4' is shown in Figs. 7a and 7b in two different rotational positions relative to the drive unit 2. The invention is of course in no way limited to the embodiments described above, but a number of possibilities for modifications thereof should be obvious to a person skilled in the art, without this deviating from the basic idea of the invention. as defined in the appended claims.
