Description of the Invention
    [003] Torque-intensifying power tools are known through recent patent application descriptions. In a first high-speed, low-torque mode, at least one intensifier mechanism rotates together with the tool housing and the tool output drive. In a second mode of low speed and high torque, at least one intensifier mechanism rotates in one direction, while the housing tends to rotate in the opposite direction. The housing is prevented from rotating by means of a reaction element connected to a stationary object.
    [004] The characteristics of the application often adversely affect the locking services and include, for example, corroded, dirty, warped, screw and nut surfaces and pins, loaded with residues, deburred, chafed, irregular, disoriented, misaligned and / or unevenly lubricated. It is often not feasible to overcome the adverse characteristics of the locking application in the first mode.
    [005] Most impact mechanisms use a mass to be rotated at high speed, which creates inertia that ends in a hammering motion. Several impact mechanisms are known and can include at least one hammer that hits a stop, while others can operate by vibration caused by interference between the power input and the drive output.
    [006] Some known impact mechanisms are efficient in overcoming several adverse characteristics of the locking application. However, the vibration absorbed by the operator at high torque, caused by the large mass of the impact mechanism, is harmful. For example, the daily European action values with exposure of the hand to the arm to vibration caused by power tools are <2.5 m / s2. Known portable impact tools with higher torque exceed this value. Therefore, the torque output in the first mode is limited to avoid damage to the operator.
    [007] The known low torque and small mass impact mechanisms can prevent injury from exposure of the operator to vibration and can be ideal for overcoming the various adverse characteristics of the locking application when attaching or releasing fasteners. Unfortunately they are not efficient for loosening corroded or tightened fasteners with high torque that are stuck in the joints and are unsuitable for the higher torque needs that generally require torque accuracy.
    [008] The use of reaction elements at high turning speeds is known to cause injury. The injury usually strikes the operator's extremities when inadvertently in the wrong place, because the reaction element can hit a stationary object. Therefore, the speed of operation of these tools is limited.
    [009] A recently described double speed torque intensifier power tool operates at very high speed to secure or loosen a nut without the need for reaction elements. This tool rotates its housing together with its torque-intensifying medium, although the operator must absorb the reaction force when the tool is operated without the reaction element. The turning force must not exceed low torque values. Otherwise, the operator's arm would succumb to the reaction force and twist as soon as the tool applied torque to overcome the adverse characteristics of the locking application. In many cases, this tool must react against a stationary object to achieve sufficient torque values to overcome the adverse characteristics of the locking application, obviously at a lower speed.
    [010] The limitations of current tools force operators to use two tools: an impact wrench to secure or loosen a nut, in the absence of adverse characteristics of the tool application, because of the high impact force, high rotation speed and low reaction force; and a torque wrench with a reaction element to tighten or loosen the nut due to the high precise and measurable torque. Impact wrenches are no longer acceptable at high torque due to inaccuracy and vibration, the latter being the cause of inflammation of the elbow. And torque wrenches are no longer acceptable at low torque due to low speed.
    [011] The present invention, therefore, was designed to overcome these problems.
    [012] In accordance with a first aspect of the invention, we present an apparatus for tightening and loosening an industrial fastener, free of reaction and assisted by reaction, including:
    [013] a motor to generate a turning force to rotate the fastener;
    [014] a turning force multiplication mechanism for a lower speed / higher torque mode, including a plurality of turning force multiplication transmitters;
    [015] a swing force impact mechanism for a higher speed / lower torque mode, including a plurality of swing force impact transmitters;
    [016] a housing operably connected to at least one multiplication transmitter;
    [017] a reaction mechanism for transferring a reaction force generated on the housing during the lowest speed / highest torque mode to a stationary object;
    [018] in which during the lowest speed / highest torque mode at least two multiplication transmitters rotate in relation to each other; and
    [019] in which during the highest speed / lowest torque mode at least two multiplication transmitters are unitary to achieve a hammering movement from the impact mechanism.
    [020] Other features of the invention are described in claims 2 to 32 attached to this report.
    [021] Advantageously, this invention addresses industrial issues and problems with a tool that: generally falls below the recommended action values with exposure to vibration, because the impact mechanism compresses only in the first mode - at low speed, high torque , the impact mechanism does not compress and therefore does not vibrate; it offers high inertia in the first mode due to a large mass resulting from the cooperation between the multiplication and impact mechanisms, which increases the torque output of the impact mechanism; attaches and loosens fasteners at high speed without the use of a reaction element, even when a torque higher than that absorbable by an operator is needed to overcome the adverse characteristics of the locking application; and loosen corroded or tightened high torque fasteners that are attached to their joints and tighten the fasteners to the highest and most accurate torque desired with the use of a reaction element in the second mode.
    [022] The invention can be described by way of example only, with reference to the accompanying drawings, in which:
    [023] Figure 1 is a perspective view of an embodiment of the present invention;
    [024] Figure 2 is a side, cross-sectional view of an embodiment of the present invention;
    [025] Figure 3 is a side, cross-sectional view of an embodiment of the present invention;
    [026] Figure 4 is a side, cross-sectional view of an embodiment of the present invention;
    [027] Figure 5 is a side, cross-sectional view of an embodiment of the present invention;
    [028] Figure 6 is a side, cross-sectional view of an embodiment of the present invention; and
    [029] Figure 7 is a side, cross-sectional view of an embodiment of the present invention.
    [030] Referring to figure 1 as an example, a perspective view of an embodiment of the present invention is shown as an apparatus 1 for tightening and loosening a reaction-free and reaction-assisted industrial fastener. Apparatus 1 includes: a drive assembly 100; an intensification set 200; a 300 mode gear / switch assembly; a rotary / inversion reaction set 400; and a security set 500.
    [031] With reference to Figure 2, by way of example, a cross-sectional view of an embodiment of the present invention as apparatus 1A is shown. Apparatus 1A is similar to apparatus 1, as indicated by duplicating reference numbers.
    [032] The drive assembly 100 may include a drive housing 101, a drive mechanism 102, a handle 104 and a switching mechanism 105. Drive means 102 generate a turning force to rotate the fastener and are shown in form of engine transmission means that include an engine. The drive mechanism 102 can also be constituted in the form of a manual drive mechanism, such as, for example, a torque wrench. The drive mechanism 102 generates a torque for operating the device 1A. The drive housing 101 is illustrated as a cylindrical body with a handle 104 that the operator holds and is provided with a switching mechanism 105 for starting and stopping the motor 102.
    [033] The intensification set 200 includes a turning force multiplication mechanism 210 substantially for a lower speed / higher torque mode including a plurality of turning force multiplication transmitters. In this embodiment, the intensification set 200 includes three multiplication transmitters 211, 212 and 213. Multiplication transmitters 211, 212 and 213 can include gear cages, planetary gears; ring gears; solar gears; oscillating gears; cycloidal gears; epicyclic gears; connectors; spacers; switching rings for retaining rings; bushings; bearings; lids; transmission gears; transmission shafts; positioning pins; driving wheels; springs; or any combination of these. Multiplication transmitters 211, 212 and 213 may include other similar components known as well.
    [034] It should be understood that there are several known impact mechanisms, although for the most part they consist of a stop and a rotating hammer. The hammer is rotated by the motor and the stop has turning resistance. This causes a hammered action, which is transmitted to the output drive. The stepping set 200 includes a swing force impact mechanism 250 substantially for a higher speed / lower torque mode including a plurality of swing force impact transmitters. In this embodiment, the intensifying assembly 200 includes two swing force impact transmitters 251 and 252. Impact transmitters 251 and 252 can include hammers; stops; connectors; spacers; switching rings for retaining rings; bushings; bearings; lids; transmission gears; transmission shafts; positioning pins; driving wheels; springs; or any combination of these. Impact transmitters 251 and 252 may also include other similar components known.
    [035] Known torque-intensifying tools are generally driven by air, electric, hydraulic or piston engines. Often the power output and the speed of rotation are increased or reduced by means of planetary gears or the like, which become part of the engine. Some known tools temporarily eliminate one or more of the intensifying media to increase the speed of rotation of the tool motor. Other known tools use gear intensification and / or reduction mechanisms as stand-alone components or adjacent to the motor to increase and / or decrease the rotation speed of the shaft. The present invention can also include such gearing and / or gearing mechanisms as stand-alone components, as multiplication transmitters and part of the multiplication mechanism 210 or as impact transmitters and part of the impact mechanism 250.
    [036] The intensification set 200 includes an intensification housing 220 operatively connected with at least one multiplication transmitter. Apparatus 1A includes a reaction mechanism 401 of reaction set 400 which is not fully shown in figures 2-7. The reaction mechanism 401 transfers a reaction force generated on the housing 220 during the lowest speed / highest torque mode to a stationary object.
    [037] Generally, the operation of device 1A requires the activation or deactivation of the impact mechanism 250, which can be performed manually with a switch. The apparatus 1A includes a switching mechanism 230 of the intensifying assembly 200 for switching the apparatus 1A between: the multiplication mechanism 210; impact mechanism 250; part of the multiplication mechanism 210 (such as, for example, a plurality of multiplication transmitters); part of the impact mechanism 250 (such as, for example, one of a plurality of impact transmitters); or any combination of these. The switching mechanism 230 may include: switching collars; switching rings; ball bearings; bearings; retaining rings or any combination of these. The switching mechanism 230 can also include other similar components known.
    [038] In operation, the RPMs of device 1A decrease while the torque output increases. The activation and deactivation of the impact mechanism 250 can alternatively be automated, so that when the RPMs fall or exceed a predetermined number, the impact mechanism 250 becomes ineffective or effective. In order to make the impact mode for industrial fasteners effective, it is recommended to take a known hammer or stop device, which consists of an impact housing, at least one hammer and a stop that is usually connected to the output tool drive that rotates the fastener.
    [039] Apparatus 1A includes an input shaft 260 to assist in transferring the rotating force of the motor 203 to: the multiplication mechanism 210; impact mechanism 250; part of the multiplication mechanism 210 (such as, for example, a plurality of multiplication transmitters); part of the impact mechanism 250 (such as, for example, one of a plurality of impact transmitters); or any combination of these. Apparatus 1A includes an output shaft 270 to assist in the transfer of the turning force to the industrial fastener via the output drive of: the multiplication mechanism 210; impact mechanism 250; part of the multiplication mechanism 210 (such as, for example, a plurality of multiplication transmitters); part of the impact mechanism 250 (such as, for example, one of a plurality of impact transmitters); or any combination of these.
    [040] Generally, the apparatus of the present invention makes use of an impact mechanism and a multiplication mechanism. In the first highest speed / lowest torque mode, the impact mechanism acts to provide a turning force for a hammer. In the second lowest speed / highest torque mode, the impact mechanism acts as an extension to transmit the turning force from one part of the tool to another. The impact mechanism can be located close to the tool motor, close to the tool exit drive or in another intermediate part.
    [041] In the first mode, the impact mechanism always receives a turning force and turns; the housing may or may not receive a turning force; and the torque output is relatively low, which is why the housing does not need to react. Note that in most embodiments of the present invention, the impact mechanism is operable only at high speed. This means, in turn, that at low speed, when the torque intensifying mechanism is operable, there is no impact so that there is also no vibration at high torque. Generally, as illustrated in figure 2, at least two multiplication transmitters are unitary to achieve a hammering movement from the impact mechanism.
    [042] The following discussion refers to figures 2-7. Note that similar terms can be exchanged with each other, such as, for example: intensifier, multiplier and multiplication; impact and impact.
    [043] More specifically, in an impact mode embodiment, the tool housing and gear stages remain stationary while the impact is shaking. When the impact mechanism is far from the motor, an axis of the motor passes through the center of the multipliers to the impact mechanism and from there to the output drive. When the impact mechanism is immediately after the engine and in front of the multipliers, the motor drives the impact mechanism and an axis runs from the impact mechanism through the center of the multipliers to the output drive.
    [044] In another embodiment of the impact mode, the tool housing and the gear stages rotate in unison while the impact trembles blocking the gear stages. This can be achieved by connecting: the solar gear with the ring gear; the solar gear with the gear cage; the gear cage with the ring gear of a planetary stage. In each case, all the gear cages and the housing act as an extension of rotation from the motor to the impact mechanism or from the impact mechanism to the output drive of the tool.
    [045] In another embodiment of the impact mode, the tool housing remains stationary and the gear cages rotate in unison, while the impact trembles blocking the gear cages together. When the impact mechanism is away from the engine, the gear cage (s) acts as an extension within the engine housing to the impact mechanism. When the impact mechanism is immediately after the engine and in front of the multipliers, the gear cages or gear cage act as an extension within the impact mechanism housing to the tool output drive.
    [046] Generally during the second lowest speed / highest torque mode, as illustrated in figure 3, at least two multiplication transmitters rotate relative to each other. In the multiplier mode, the tool housing always rotates in opposition to the solar gears and the output shaft of the multipliers, which is why the tool housing has to react. When the torque is intensified by the multiplier, the turning speed is so low that the impact mechanism is ineffective. If the impact mechanism is located after the multiplier and close to the tool's output drive, the impact mechanism will not impact if it rotates with the last solar gear. If the impact mechanism is located before the multiplier and close to the engine, the impact mechanism rotates at high speed and needs to be blocked.
    [047] In an embodiment in which the impact mechanism is distant from the engine, the following occurs: the impact mechanism remains stationary while the multipliers rotate; the motor output shaft goes to the multiplier for torque multiplication; and the last solar gear extends through the impact mechanism to the output drive. When the impact mechanism is immediately after the engine and in front of the multipliers, the motor's output shaft passes through the impact mechanism to the multiplier for torque multiplication and the last solar gear extends to the output drive.
    [048] In another embodiment, the impact mechanism rotates at the speed of the last solar gear of the force multipliers. When the impact mechanism is far from the motor, the motor output shaft goes to the multiplier for torque multiplication and the last solar gear rotates the impact mechanism, which rotates the tool output shaft. When the impact mechanism is immediately after the engine and in front of the multipliers, turning the impact mechanism to rotate the multipliers would result in an impact, which should be avoided. On the other hand, the impact mechanism can be blocked by locking the hammer with the impact housing, or by locking the hammer with the stop. The impact mechanism acts as an extension between the motor output and the first multiplier solar gear.
    [049] The speed of the last multiplier solar gear can be high enough to operate the impact mechanism. Impact on the output shaft of the tool can be avoided by locking the hammer with the impact housing, the hammer with the stop, the impact housing with the tool housing or the hammer with the tool housing.
    [050] In a specific embodiment of the first mode, as, for example, illustrated in the upper half of figure 6, the multiplication mechanism is close to the engine and before the impact mechanism. The motor bypasses the multiplication mechanism and extends its output force by passing at least part of the multiplication mechanism by means of a pin in the direction of the output drive. In a specific embodiment of the first mode, as, for example, illustrated in the upper half of figure 7, the impact mechanism is close to the motor and before the multiplication mechanism. The impact mechanism extends its output force by passing at least a part of the multiplication mechanism by means of a pin in the direction of the output drive.
    [051] An embodiment of a complete tool of the present application may include an engine housing equipped with an impact mechanism just after the air motor, which has an orifice that runs through it. A pin that protrudes through the back plate of the tool and is connected to a security plate, as described and claimed in United States patent application No. 12 / 120,346, with filing date of May 14, 2008, entitled “ Safety Torque Intensifying Tool ”. The pin is, for example, a groove connected to the motor and movable along its axis. The front of the pin rotates the hammer of the impact mechanism. The output drive of the impact mechanism is grooved, but has a part with a round diameter between the grooved part and where it exits the impact mechanism.
    [052] The planetary housing has internal grooves called ring gear. A round plate with external grooves is connected to the end of the planetary housing just in front of the first gear stage and the output drive of the impact mechanism engages a female groove in the round plate and also acts as the first solar gear. The round plate has a notch at the top of the groove. Two thin plates with a hole at one end and with a perpendicular part that passes through two notches in the motor housing handle to connect with two pins that move axially backwards when the safety plate is pushed to engage a reaction arm. These reaction arms are described and claimed in: United States Patent Application no. 11 / 745,014, with Deposit Date of May 7, 2007, entitled “Power-Driven Torque Intensifier”; United States Patent No. 7,798,038, with Grant Date of September 21, 2010, entitled “Reaction Arm For Power-Driven Torque Intensifier”; United States Patent Application No. 12 / 325,815, with Filing Date of December 1, 2008, entitled “Torque Power Tool”. The holes have a ball bearing in them to connect the round plate to the plates. At high speed, this means that the planetary housing is free to rotate in relation to the handle of the motor housing. To secure, when the safety plate is not pushed in and when the speed lever is pressed down, the impact mechanism causes the impact.
    [053] When the speed lever is released, the reaction arm is placed in position and the safety plate is pressed, the following occurs simultaneously: a hitch plate moves from the grooved part of the output drive to its diameter part round; the coupling plate disengages from the planetary housing and moves into the handle of the motor housing; the reaction arm engages; the pin moves forward and connects with the stop to prevent the impact mechanism from working, but be able to be rotated as a unit to rotate the planetary gears. The planetary housing is free to rotate in relation to the engine housing handle.
    [054] With reference again to Figure 1, the components of apparatus 1 can still be explained with reference to the technology described in the following patents and common patent applications, the complete copies of which are hereby incorporated by reference: Patent Application in the United States at the. 11 / 745,014, with Deposit Date of May 7, 2007, entitled “Power-Driven Torque Intensifier”; United States Patent No. 7,798,038, with Concession Dated September 21, 2010, entitled “Reaction Arm For Power-Driven Torque Intensifier”; United States Patent Application No. 12 / 120,346, with Filing Date of May 14, 2008, entitled “Safety Torque Intensifying Tool”; United States Patent Application No. 12 / 325,815, with Filing Date of December 1, 2008, entitled “Torque Power Tool”; and United States Patent Application No. 12 / 428,200, filed April 22, 2009, entitled “Reaction Adaptors for Torque Power Tools and Methods of Using the Same”.
