Description

Technical Field

[0001] The invention relates to the technical field of workpiece fixing equipment for gearbox assembly, in particular to a tool for gearbox assembly. Background Art

[0002] A gearbox is a mechanism used to change the speed, torque, or direction of power output from a power source. It can change the transmission ratio between the output and input shafts in fixed or step-by-step manner, and can also change the transmission direction of the output and input shafts as needed. Gearboxes with an output and input shaft at a 90-degree angle are widely used.

[0003] Existing gearboxes with output and input shafts at 90° angles present significant assembly difficulties. This is primarily due to the fact that while the transmission components on the upward side of the gearbox are relatively easy to assemble, the assembly of the transmission components on the horizontal side of the gearbox is more difficult. To reduce the difficulty of assembling the transmission components on the horizontal side of the gearbox, a tool that can flip the gearbox housing upward 90° has begun to be used. While this type of gearbox assembly tool can improve the overall assembly convenience of the gearbox, it still suffers from the following drawbacks in actual use: 1) After the gearbox housing is flipped upward 90°, it is mounted on the tool in a suspended position, resulting in significant uneven force on both the gearbox housing and the tool, making it difficult to achieve the design service life of the tool and easily affecting the assembly accuracy of the gearbox components. 2) The gearbox is difficult to flip, which not only increases labor intensity but also poses a safety hazard.

[0004] Therefore, the research purpose of this invention is to design a gearbox assembly tool that can not only effectively facilitate the flipping operation of the gearbox, but also provide stable support for the flipped gearbox without interference, thereby effectively improving the service life of the tool and achieving high-precision assembly of the gearbox while reducing labor intensity and ensuring assembly safety. Summary of the Invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a tool for assembling a gearbox, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A tool for assembling a gearbox, comprising:

[0008] The support assembly includes support uprights fixed to both sides of the chassis, the upper portions of the support uprights being fixedly connected to corresponding fixing seats, the fixing seats being rotatably mounted with corresponding connecting shafts, the inner sides of the connecting shafts being fixedly connected to corresponding connecting plates, and the gearbox housing being fixedly mounted between the connecting plates;

[0009] A turning assist assembly includes a limiting elastic member having one end fixedly connected to the connecting shaft member, and the other end of the limiting elastic member fixedly connected to the fixing seat. When the transmission housing is located on the bottom side of the connecting plate member, the limiting elastic member is stretched or compressed. When the transmission housing is turned upward by 90 degrees, the limiting elastic member recovers its deformation.

[0010] A tightening support member is movably mounted on the chassis. When the gearbox housing is located on the bottom side of the connecting plate, the tightening support member is located on the bottom side of the gearbox housing. When the gearbox housing is flipped upward by 90°, the tightening support member is lifted upward until a gap is formed between the top end thereof and the bottom end of the gearbox housing.

[0011] The support and reinforcement mechanism includes a plug-in shaft which is laterally movably inserted into the chassis, and a group of plug-in holes are arranged on the tightening support member according to height; when the tightening support member is on the bottom side of the gearbox housing, the plug-in shaft is inserted into the plug-in hole on the top side of the tightening support member; when the tightening support member is lifted upward to a gap between its top end and the bottom end of the gearbox housing, the plug-in shaft is inserted into the plug-in hole on the bottom side of the tightening support member and drives the tightening support member upward so that the top end of the tightening support member is tightened to the bottom side of the gearbox housing.

[0012] A first electromagnet for adsorbing and fixing the tightening support member is provided in the chassis, and the bottom of the tightening support member is fixed to the upper side of the first electromagnet through a corresponding first lifting spring; a second electromagnet for adsorbing and fixing the plug-in shaft member is also provided in the chassis, and the end of the plug-in shaft member is fixed to the end of the second electromagnet through a corresponding second lifting spring.

[0013] When the gearbox housing is located on the bottom side of the connecting plate, the second electromagnet is energized to adsorb and drive the plug-in shaft away from the tightening support; then the first electromagnet is energized to adsorb and drive the tightening support so that the plug-in hole on the top side of the tightening support faces the plug-in shaft, and then the second electromagnet is de-energized, and the plug-in shaft moves and is plugged into the plug-in hole on the top side of the tightening support under the action of the second lifting spring to fix the tightening support on the bottom side of the gearbox housing.

[0014] When the gearbox housing is flipped upward by 90°, the second electromagnet is energized to adsorb and drive the plug-in shaft away from the clamping support; then the first electromagnet is de-energized, and the clamping support is lifted upward by the drive of the first lifting spring until a gap is formed between the top end thereof and the bottom end of the gearbox housing; then the second electromagnet is de-energized, and the plug-in shaft is moved and plugged into the plug-in hole on the bottom side of the clamping support under the action of the second lifting spring.

[0015] The middle part of the plug-in shaft is hollow and has a corresponding pushing part installed upward so as to be lifted and lowered. A corresponding limiting hole is provided on the side of the chassis where the plug-in shaft is not provided. A boosting mechanism is provided in the limiting hole for injecting the corresponding boosting medium into the hollow part of the plug-in shaft.

[0016] The boosting mechanism adopts an air nozzle, which is connected to an external pneumatic control system through a corresponding air pipe. When the plug-in shaft is plugged into the plug-in hole on the bottom side of the tightening support, the external pneumatic control system injects high-pressure gas into the hollow part of the plug-in shaft to drive the pushing member to move upward to drive the tightening support upward, so that the top end of the tightening support is tightened to the bottom side of the gearbox housing; before the plug-in shaft leaves the plug-in hole of the tightening support, the air pipe is pre-depressurized.

[0017] A corresponding flexible member is fixed to the upper portion of the tightening support member. When the top end of the tightening support member is driven to tighten against the bottom side of the gearbox housing, the flexible member is in a compressed state and is located between the tightening support member and the gearbox housing.

[0018] The connecting shafts are respectively fixed upward with corresponding limiting rods, the ends of the limiting rods are arranged in an arc-shaped slope, and the middle parts of the front sides thereof are respectively fixed forward with corresponding handles, and the rear sides of the fixing seats are respectively provided with clamping mechanisms for limiting and fixing the limiting rods. When the gearbox housing is flipped upward by 90°, the limiting rods are clamped by the clamping mechanisms.

[0019] The clamping mechanism includes a fixed block, a corresponding notch is provided on the side of the fixed block facing the limiting rod, and an open groove is provided on the other side of the fixed block; a clamping rod is movably installed in the fixed block between the notch and the open groove, the front end top of the clamping rod is arranged in an inclined shape, and the rear end of the clamping rod is fixedly connected to the corresponding metal plate backward through a rubber block, and the upper rear end of the metal plate is fixedly connected to a return spring abutting against the fixed block, and a corresponding pressure gauge is provided on the fixed block on the bottom side of the return spring; the upper end of the clamping rod is tilted forward and a corresponding pull rod is installed, and the rear side of the pull rod is fixedly connected to the corresponding guide rod in a horizontal arc shape, and the upper front side of the metal plate is provided with a fixing ring for buckling the guide rod.

[0020] Advantages of the present invention:

[0021] 1) The present invention adds a flip assist assembly, which includes a limit elastic member with one end fixed to the connecting shaft, and the other end of the limit elastic member fixedly connected to a fixed seat. When the transmission housing is located on the bottom side of the connecting plate, the limit elastic member is stretched or compressed. When the transmission housing is flipped upward 90°, the limit elastic member recovers its deformation. This reduces the resistance to the rotation of the connecting shaft when the transmission housing is flipped downward 90°, thereby preventing the transmission housing from falling rapidly during downward flipping, thereby improving assembly safety. Furthermore, when the transmission housing is flipped upward 90°, the restorative force of the limit elastic member effectively reduces the force required to flip the transmission housing upward 90°, thereby effectively facilitating the transmission flipping operation, reducing labor intensity, and ensuring assembly safety.

[0022] 2) The present invention adds a tightening support member to the chassis. When the gearbox housing is located on the bottom side of the connecting plate, the tightening support member is located on the bottom side of the gearbox housing to prevent interference with the gearbox housing's upward turning. When the gearbox housing is turned upward by 90 degrees, the tightening support member is lifted upward until its top end is spaced apart from the bottom end of the gearbox housing. Then, after the plug-in shaft of the support reinforcement mechanism is inserted into the plug-in hole on the bottom side of the tightening support member, the support reinforcement mechanism drives the tightening support member upward, causing the top end of the tightening support member to tighten against the bottom side of the gearbox housing. This is because, due to machining accuracy, if the tightening support member is directly lifted upward until it contacts the bottom end of the gearbox housing before the plug-in shaft is plugged into place, then if there is a height deviation at the bottom end of the gearbox housing, the bottom plug-in hole of the tightening support member will inevitably be misaligned with the plug-in shaft member, either resulting in the subsequent plug-in shaft member failing to plug into place normally, or the plug-in shaft member failing to provide effective support to the tightening support member after being plugged into place.

[0023] When the gearbox housing is flipped upward by 90 degrees, the present invention preliminarily lifts the tightening support member upward until a gap is formed between its top end and the bottom end of the gearbox housing to ensure that the travel of the tightening support member is not affected, thereby facilitating the insertion of the plug-in shaft member into position. Then, after the plug-in shaft member of the support reinforcement mechanism is inserted into the insertion hole on the bottom side of the tightening support member, the support reinforcement mechanism drives the tightening support member upward, so that the top end of the tightening support member presses against the bottom side of the gearbox housing, thereby fully supporting the gearbox housing by the actively driven tightening support member, thereby effectively ensuring that the plug-in shaft member can provide sufficient support to the tightening support member after being inserted into position. In this way, stable support for the flipped gearbox is achieved without interference, thereby effectively improving the service life of the tooling and achieving high-precision assembly of the gearbox.

[0024] 3) The plug-in shaft of the present invention is hollow in the middle and has a corresponding push piece installed upward so as to be lifted and lowered. A corresponding limiting hole is provided on the side of the chassis where the plug-in shaft is not provided. A boosting mechanism is provided in the limiting hole for injecting the corresponding pressurized medium into the hollow part of the plug-in shaft. When the plug-in shaft is plugged into the plug-in hole on the bottom side of the tightening support, the external pneumatic control system injects high-pressure gas into the hollow part of the plug-in shaft to drive the push piece upward to drive the tightening support so that the top end of the tightening support is pressed against the bottom side of the gearbox housing. Before the plug-in shaft leaves the plug-in hole of the tightening support, the air pipe is pre-depressurized. Through the non-standard design of the plug-in shaft and the coordinated design of the push piece and the boosting mechanism, the plug-in shaft can smoothly drive the push piece upward after being plugged into the plug-in hole on the bottom side of the tightening support, thereby effectively ensuring the practical effect of the present invention.

[0025] 4) The present invention's top support is secured to a corresponding flexible member. When the top end of the support is driven to press against the bottom of the transmission housing, the flexible member is compressed and positioned between the support and the transmission housing. This flexible member compensates for machining errors in the transmission housing to a certain extent, ensuring effective support while effectively preventing the support from excessively impacting the bottom of the transmission housing.

[0026] 5) The connecting shafts of the present invention are respectively fixed upward with corresponding limiting rods, and the rear sides of the fixing seats are respectively provided with clamping mechanisms for limiting and fixing the limiting rods. When the transmission case is flipped upward by 90°, the limiting rods are clamped by the clamping mechanisms, thereby cooperating with the tightening support members to enhance the positioning effect of the transmission case after being flipped upward by 90°.

[0027] 6) The clamping mechanism of the present invention includes a fixed block, in which a clamping rod is movably installed between the notch and the opening groove of the fixed block, and the rear end of the clamping rod is fixedly connected to the corresponding metal plate backward through a rubber block, and the upper part of the rear end of the metal plate is fixedly connected to the rear end of a reset spring that abuts against the fixed block, and a corresponding pressure gauge is provided on the fixed block on the bottom side of the reset spring; the most important thing is: the upper end of the clamping rod of the present invention is tilted and swung forward to install a corresponding pull rod, the rear side of the pull rod is fixedly connected to the corresponding guide rod in a horizontal arc shape, and the upper front side of the metal plate is provided with a fixing ring for buckling on the guide rod.

[0028] After the gearbox housing is flipped upward 90° and the corresponding components are assembled, the corresponding lifting mechanism removes the assembled gearbox and reloads the next gearbox housing. The lever is then manually pulled backward using a pull rod. The pull rod swings backward, driving the guide rod to move around the fixing ring, thereby driving the fixing ring and the metal plate forward, compressing the rubber block forward. The lever is then pulled backward again, disengaging the lever and the limit rod. During this process, the pressure gauge is subjected to relatively little force from the metal plate, allowing the gearbox housing to be switched to a position located under the connecting plate. After the partial components are assembled, the gearbox housing is manually flipped upward 90° using a handle. During this process, the rubber block is not compressed, and the pressure gauge is subjected to relatively large force from the metal plate, switching the gearbox housing to a 90° upward flip. This effectively switches the position of the gearbox housing of the present invention, ensuring the control accuracy of the switching of various components such as the support member between different states, thereby further effectively ensuring the practical effect of the present invention.

DETAILED DESCRIPTION

[0036] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments and the accompanying drawings:

[0037] refer to Figure 1-6 , a tool for assembling a gearbox, comprising:

[0038] The support assembly 1 includes support rods 101 fixed to both sides of the chassis 2. The upper portions of the support rods 101 are fixedly connected to corresponding fixing seats 102. The fixing seats 102 are rotatably mounted with corresponding connecting shafts 103. The inner sides of the connecting shafts 103 are fixedly connected to corresponding connecting plates 104. The gearbox housing 3 is fixedly mounted between the connecting plates 104.

[0039] The turning assist assembly 4 includes a limiting elastic member 401 whose end is fixed to the connecting shaft 103, and the other end of the limiting elastic member 401 is fixedly connected to the fixing seat 102 (the limiting elastic member 401 in this embodiment is a coil spring, which is sleeved on the connecting shaft 103, with one end mounted to the connecting shaft 103 via a fixing plate 402 and the other end fixed to the fixing seat 102). When the transmission housing 3 is located on the bottom side of the connecting plate 104, the limiting elastic member 401 is tightened and compressed. When the transmission housing 3 is turned upward by 90°, the limiting elastic member 401 recovers its deformation;

[0040] The jacking support member 5 is movably mounted on the chassis 2. When the gearbox housing 3 is located on the bottom side of the connecting plate 104, the jacking support member 5 is located on the bottom side of the gearbox housing 3. When the gearbox housing 3 is turned upward by 90°, the jacking support member 5 is lifted upward until a gap is formed between the top end thereof and the bottom end of the gearbox housing 3.

[0041] The support and reinforcement mechanism 6 includes a plug-in shaft 601 that is laterally movable and inserted into the chassis 2, and a group of plug-in holes 7 are arranged on the tightening support member 5 according to height; when the tightening support member 5 is on the bottom side of the gearbox housing 3, the plug-in shaft 601 is inserted into the plug-in hole 7 on the top side of the tightening support member 5; when the tightening support member 5 is lifted upward to a gap between its top end and the bottom end of the gearbox housing 3, the plug-in shaft 601 is inserted into the plug-in hole 7 on the bottom side of the tightening support member 5, and drives the tightening support member 5 upward, so that the top end of the tightening support member 5 is tightened to the bottom side of the gearbox housing 3.

[0042] The present invention further includes a tilt assist assembly 4, which includes a limit elastic member 401 having one end fixedly connected to the connecting shaft 103. The other end of the limit elastic member 401 is fixedly connected to the fixing seat 102. When the transmission housing 3 is located at the bottom side of the connecting plate 104, the limit elastic member 401 is screwed and compressed. When the transmission housing 3 is tilted upward by 90°, the limit elastic member 401 recovers its deformation. This reduces the resistance to the rotation of the connecting shaft 103 when the transmission housing 3 is tilted downward by 90°, thereby preventing the transmission housing from falling rapidly during the downward tilt, thereby improving assembly safety. Furthermore, when the transmission housing 3 is tilted upward by 90°, the restoring force of the limit elastic member 401 effectively reduces the force required to tilt the transmission housing 3 upward by 90°, thereby effectively facilitating the gearbox tilting operation, reducing labor intensity, and ensuring assembly safety.

[0043] The present invention adds a tightening support member 5 to the chassis 2. When the gearbox housing 3 is located on the bottom side of the connecting plate 104, the tightening support member 5 is located on the bottom side of the gearbox housing 3 to prevent the gearbox housing 3 from causing travel interference when flipping upward; and when the gearbox housing 3 is flipped upward by 90°, the tightening support member 5 is lifted upward until the top end thereof is gapped with the bottom end of the gearbox housing 3. Then, after the plug-in shaft 601 of the support reinforcement mechanism 6 is inserted into the plug-in hole on the bottom side of the tightening support member 5, the support reinforcement mechanism 6 drives the tightening support member 5 upward so that the top end of the tightening support member 5 is tightened to the bottom side of the gearbox housing 3. This is because: due to the influence of processing accuracy, if the clamping support 5 is directly lifted upward to contact the bottom end of the transmission housing 3, and then the plug-in shaft 601 is plugged into place, then once the height of the bottom end of the transmission housing 3 deviates, the position of the bottom side plug-in hole of the clamping support 5 will inevitably be unable to align with the plug-in shaft 601, which will either cause the subsequent plug-in shaft 601 to fail to be plugged into place normally, or cause the plug-in shaft 601 to fail to provide effective support to the clamping support 5 after being plugged into place.

[0044] When the gearbox housing 3 is flipped upward by 90°, the present invention preliminarily lifts the top support member 5 upward until a gap is formed between its top end and the bottom end of the gearbox housing 3 to ensure that the travel of the top support member 5 is not affected, thereby facilitating the insertion of the plug-in shaft 601 into place. Then, after the plug-in shaft 601 of the support reinforcement mechanism 6 is inserted into the insertion hole on the bottom side of the top support member 5, the support reinforcement mechanism 6 drives the top support member 5 upward, so that the top end of the top support member 5 is pressed against the bottom side of the gearbox housing 3, so as to fully support the actively driven top support member 5 on the gearbox housing 3, thereby effectively ensuring that the plug-in shaft 601 can provide sufficient support to the top support member 5 after being inserted into place. In this way, the gearbox can be stably supported after being flipped without interference, thereby effectively improving the service life of the tooling and achieving high-precision assembly of the gearbox.

[0045] The chassis 2 is provided with a first electromagnet 8 for adsorbing and fixing the tightening support member 5, and the bottom of the tightening support member 5 is fixed to the upper side of the first electromagnet 8 through a corresponding first lifting spring 9; the chassis 2 is also provided with a second electromagnet 10 for adsorbing and fixing the plug-in shaft 601, and the end of the plug-in shaft 601 is fixed to the end of the second electromagnet 10 through a corresponding second lifting spring 11.

[0046] When the gearbox housing 3 is located on the bottom side of the connecting plate 104, the second electromagnet 10 is energized to adsorb and drive the plug-in shaft 601 away from the clamping support 5; then the first electromagnet 8 is energized to adsorb and drive the clamping support 5, so that the plug-in hole 7 on the top side of the clamping support 5 is facing the plug-in shaft 601, and then the second electromagnet 10 is de-energized, and the plug-in shaft 601 moves and is plugged into the plug-in hole 7 on the top side of the clamping support 5 under the action of the second lifting spring 11, so as to fix the clamping support 5 on the bottom side of the gearbox housing 3.

[0047] When the gearbox housing 3 is flipped upward by 90°, the second electromagnet 10 is energized to adsorb and drive the plug-in shaft 601 away from the clamping support 5; then the first electromagnet 8 is de-energized, and the clamping support 5 is lifted upward by the first lifting spring 9 until a gap is formed between its top end and the bottom end of the gearbox housing 3, and then the second electromagnet 10 is de-energized, and the plug-in shaft 601 is moved and plugged into the plug hole 7 on the bottom side of the clamping support 5 under the action of the second lifting spring 11.

[0048] The middle part of the plug-in shaft 601 is hollow and has a corresponding pushing member 602 installed upward so as to be lifted and lowered. A corresponding limiting hole is provided on the side of the chassis 2 where the plug-in shaft 601 is not provided. A boosting mechanism 603 is provided in the limiting hole for injecting the corresponding boosting medium into the hollow part of the plug-in shaft 601.

[0049] The boosting mechanism 603 adopts an air nozzle, which is connected to an external pneumatic control system through a corresponding air pipe 12. When the plug-in shaft 601 is plugged into the plug-in hole 7 on the bottom side of the tightening support 5, the external pneumatic control system injects high-pressure gas into the hollow part of the plug-in shaft 601 to drive the pushing member 602 to move upward to drive the tightening support 5 upward, so that the top end of the tightening support 5 is tightened to the bottom side of the gearbox housing 3; before the plug-in shaft 601 leaves the plug-in hole 7 of the tightening support 5, the air pipe 12 is pre-depressurized.

[0050] Through the non-standard design of the plug-in shaft 601, and the coordinated design of the push member 602 and the boosting mechanism 603, the plug-in shaft 601 can smoothly drive the push member 602 upward after being plugged into the plug-in hole on the bottom side of the tightening support member 5, thereby effectively ensuring the practical effect of the present invention.

[0051] A corresponding flexible member 13 is fixedly connected to the upper portion of the pressing support member 5. When the top end of the pressing support member 5 is driven to press against the bottom side of the transmission housing 3, the flexible member 13 is compressed and located between the pressing support member 5 and the transmission housing 3. The intervention of the flexible member 13 can compensate for the machining errors of the transmission housing 3 to a certain extent, thereby ensuring the supporting effect while effectively preventing the pressing support member 5 from excessively impacting the bottom of the transmission housing 3.

[0052] The connecting shafts 103 are each upwardly fixedly connected to a corresponding limiting rod 14. The ends of the limiting rods 14 are arranged in an arc-shaped sloped shape, and corresponding handles 15 are fixed forwardly to the middle of their front sides. The rear sides of the fixing seats 102 are each provided with a clamping mechanism 16 for limiting and fixing the limiting rods 14. When the transmission case 3 is turned upward by 90°, the limiting rods 14 are clamped by the clamping mechanism 16. This forms a cooperation with the tightening support member 5 to enhance the positioning effect of the transmission case 3 after it is turned upward by 90°.

[0053] The clamping mechanism 16 includes a fixed block 1601, a corresponding notch 17 is provided on the side of the fixed block 1601 facing the limiting rod 14, and an open slot 18 is provided on the other side of the fixed block 1601; a clamping rod 1602 is movably installed in the fixed block 1601 and is located between the notch and the open slot, the front end top of the clamping rod 1602 is arranged in an inclined shape, and the rear end of the clamping rod 1602 is fixedly connected to the corresponding metal plate 1604 through a rubber block 1603. The upper rear end of the metal plate 1604 is fixedly connected to a return spring 1605 that abuts against the fixed block 1601, and a corresponding pressure gauge 19 is provided on the fixed block 1601 on the bottom side of the return spring 1605; the upper end of the clamping rod 1602 is tilted forward and swung to install a corresponding pull rod 20, and the rear side of the pull rod 20 is fixedly connected to the corresponding guide rod 21 in a horizontal arc shape, and the upper front side of the metal plate 1604 is provided with a fixing ring 22 for buckling onto the guide rod 21.

[0054] After the gearbox housing 3 is turned upward by 90 degrees and the corresponding components are assembled, the corresponding hoisting mechanism takes away the assembled gearbox and re-loads the next gearbox housing 3 into place; then the lever 20 is manually pulled backward to pull the clamping rod 1602. At this time, the lever 20 swings backward, thereby driving the guide rod 21 to move around the fixing ring 22, thereby driving the fixing ring 22 and the metal plate 1604 to move forward, so that the rubber block 1603 is compressed forward, and then the clamping rod 1602 is pulled backward to make the clamping rod 1602 The rubber block 1603 is not compressed, and the pressure gauge 19 is subjected to a relatively large force from the metal plate 1604, which causes the gearbox housing 3 to be switched upwards by 90°. This effectively switches the position of the gearbox housing 3 of the present invention precisely, ensuring the control accuracy of the switching of various components such as the tightening support member 5 under different states, thereby further effectively ensuring the practical effect of the present invention.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
