Technical Field
[0001] This utility model relates to the field of gear reducer disassembly technology, and in particular to a gear reducer repair and disassembly device. Background Technology
[0002] As the core power hub of industrial transmission systems, gear reducers play a crucial role in speed reduction and torque increase in various mechanical equipment such as machine tools, lifting equipment, and automated production lines. Their internal precision gear pairs and shaft components achieve speed and torque conversion through complex meshing transmission. Therefore, after long-term operation, gear wear, bearing failure, and other faults are inevitable, requiring frequent disassembly and maintenance.
[0003] Currently, the gear reducer disassembly devices in existing technologies mainly adopt a screw-type clamping structure, which uses a motor to rotate the screw to open and close the clamping claws. For gear reducers of different specifications, the screw needs to be rotated repeatedly to adjust the clamping distance. However, the mechanical characteristics of screw transmission result in slow adjustment speed, making it impossible to achieve quick clamping and release. At the same time, noise will be generated during long-term operation, affecting the surrounding environment of the equipment. Utility Model Content
[0004] The present invention addresses the shortcomings of using a motor-driven rotating screw to open and close the clamping jaws. For gear reducers of different specifications, the screw needs to be repeatedly rotated to adjust the clamping distance. However, the mechanical characteristics of the screw drive result in slow adjustment speed, making it impossible to achieve quick clamping and releasing. In addition, long-term operation generates noise, which affects the surrounding environment of the equipment. This invention provides a gear reducer maintenance and disassembly device with the advantages of quick clamping and releasing, high stability, and low noise pollution, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a gear reducer repair and disassembly device, including a base, a turntable installed on the upper end of the base, two clamping seats provided on the upper end of the turntable, a servo motor installed on the middle of the outer side of the clamping seats, a cam installed on the inner side of the clamping seats, the servo motor connected to one side of the cam via a coupling, two connecting rods rotatably installed at both ends of the side of the cam away from the servo motor, two slide rails opened on the inner side of the clamping seats, two clamping plates provided at both ends of the inner side of the clamping seats, sliders fixedly installed on the side of the clamping plates, the sliders slidably installed inside the slide rails respectively, a fixing rod fixedly installed at the end of the clamping plate near the slider, and the connecting rods rotatably installed on the outer wall of the fixing rod at the ends away from the cam.
[0006] Preferably, a rotary motor is installed at the bottom of the base, and the upper end of the rotary motor is connected to the bottom of the turntable via a coupling.
[0007] By using a rotary motor, the turntable is driven to rotate and adjust the angle of the clamping seat, enabling flexible adjustment of the disassembly position and improving the adaptability of the device.
[0008] Preferably, two hinge seats are fixedly installed on the upper end of the turntable, and hinge shafts are fixedly installed on the bottom of the two clamping seats. The two sides of the hinge shafts are rotatably installed on the inner side of the hinge seats.
[0009] By using the rotatable connection between the hinge shaft and the hinge seat, the clamping seat can swing around the shaft to adjust the angle, achieving adaptive clamping for reducers of different specifications and enhancing the flexibility of the device.
[0010] Preferably, a forward and reverse motor is mounted on the outer side of one of the hinge seats, and a drive rod is rotatably mounted on the bottom of both hinge seats. The forward and reverse motor is connected to one side of the drive rod via a coupling.
[0011] Preferably, two drive gears are fixedly installed on both sides of the drive rod, and a semi-circular gear is fixedly installed at the bottom of each of the two hinge seats. The upper end of the drive gear meshes with the bottom of the semi-circular gear.

[0013] Preferably, a protective shell is fixedly installed at the upper center of the turntable, the drive rod is located inside the protective shell, a placement box is fixedly installed at the bottom of the base, and multiple tool boxes are slidably installed on the inner side of the placement box.
[0014] The protective casing protects the drive rod and other transmission components, preventing dust and oil from entering and extending the service life of the device.
[0015] This utility model has the following advantages:
[0016] 1. By setting up a servo motor, cam, and linkage transmission mechanism, when the servo motor drives the cam to rotate, the cam drives the clamping plate to slide synchronously along the slide rail through the connecting rods at both ends. The curve characteristics of the cam profile are used to realize the rapid opening and closing of the clamping plate. Compared with the traditional screw drive rotation adjustment method, the clamping efficiency is significantly improved. At the same time, the guiding cooperation between the slide rail and the slider can minimize the displacement error of the clamping plate, so that the clamping force is evenly applied to the gear shaft and other components, avoiding the deformation or damage of components due to uneven force. This solves the problems of slow adjustment and poor clamping synchronization in the existing technology.
[0017] 2. By setting up a rotary motor, turntable, hinged seat, and gear transmission assembly, the rotary motor drives the turntable to rotate and adjust the angle of the clamping seat. The forward and reverse motors achieve dynamic adjustment of the opening and closing angle of the two clamping seats through the meshing transmission of the drive rod, the active gear, and the semi-circular gear. It can adapt to the disassembly requirements of gear reducers of different specifications without the need to replace the clamping assembly. Compared with the sliding friction of the screw and nut, the mechanical structure of gear meshing transmission has less mechanical vibration and higher transmission accuracy, effectively reducing noise pollution and equipment wear during disassembly, and improving the versatility and stability of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4A gear reducer repair and disassembly device includes a base 1, a turntable 2 mounted on the upper end of the base 1, two clamping seats 7 on the upper end of the turntable 2, a servo motor 8 mounted on the outer center of the clamping seats 7, and a cam 9 mounted on the inner side of the clamping seats 7. The servo motor 8 is connected to one side of the cam 9 via a coupling. Two connecting rods 10 are rotatably mounted at both ends of the side of the cam 9 away from the servo motor 8. A transmission mechanism is set up for the servo motor 8, the cam 9, and the connecting rods 10. When the servo motor 8 drives the cam 9 to rotate, the cam 9 drives the clamping plate 13 along the direction of rotation via the connecting rods 10. The slide rails 11 slide synchronously, and two slide rails 11 are provided on the inner side of the clamping seat 7. Two clamping plates 13 are provided at both ends of the inner side of the clamping seat 7. The curve characteristics of the cam 9 contour are used to realize the rapid opening and closing of the clamping plates 13. Compared with the traditional screw drive rotation adjustment method, the clamping efficiency is significantly improved. At the same time, the guide cooperation between the slide rails 11 and the slider 12 can minimize the displacement error of the clamping plates 13, so that the clamping force is evenly applied to the gear shaft and other components, avoiding the deformation or damage of components due to uneven force, and solving the problems of slow adjustment and poor clamping synchronization in the prior art.
[0025] A slider 12 is fixedly installed on the side of the clamping plate 13. The slider 12 is slidably installed inside the slide rail 11 to guide the clamping plate 13 to slide smoothly along a straight line, ensuring the clamping displacement accuracy and avoiding uneven force on the component caused by the clamping plate 13 shaking. A fixing rod 14 is fixedly installed at the end of the clamping plate 13 near the slider 12. The end of the connecting rod 10 away from the cam 9 is rotatably installed on the outer wall of the fixing rod 14. The setting of the fixing rod 14 provides a rotation connection fulcrum for the connecting rod 10, so that when the cam 9 rotates, the connecting rod 10 can stably transmit the driving force to the clamping plate 13, ensuring the synchronization and stability of the clamping action.
[0026] Please see Figures 2-3 A rotary motor 3 is installed at the bottom of the base 1. The upper end of the rotary motor 3 is connected to the bottom of the turntable 2 through a coupling. When the rotary motor 3 is working, it can drive the turntable 2 to rotate, thereby driving the clamping seat 7 above to adjust the angle. This allows the device to flexibly adapt to reducers in different positions, improving the convenience and adaptability of disassembly operations. Two hinge seats 6 are fixedly installed at the upper end of the turntable 2. A hinge shaft 15 is fixedly installed at the bottom of each of the two clamping seats 7. The two sides of the hinge shaft 15 are rotatably installed on the inner side of the hinge seat 6.
[0027] A forward and reverse motor 17 is installed on the outer side of one of the hinge seats 6. A drive rod 18 is rotatably installed on the bottom of both hinge seats 6. The forward and reverse motor 17 is connected to one side of the drive rod 18 through a coupling. Two drive gears 19 are fixedly installed on both sides of the drive rod 18. A semi-circular gear 16 is fixedly installed on the bottom of both hinge seats 6. The upper end of the drive gear 19 is meshed with the bottom of the semi-circular gear 16. A rotary motor 3, a turntable 2, hinge seats 6 and a gear transmission assembly are set up. The rotary motor 3 drives the turntable 2 to rotate the clamping seat 7 to adjust the angle. The forward and reverse motor 17 realizes the dynamic adjustment of the opening and closing angle of the two clamping seats 7 through the meshing transmission of the drive rod 18, the drive gear 19 and the semi-circular gear 16. It can adapt to the disassembly requirements of gear reducers of different specifications without replacing the clamping assembly. Compared with the sliding friction of screw and nut, the mechanical structure of gear meshing transmission has less mechanical vibration and higher transmission accuracy, effectively reducing noise pollution and equipment wear during disassembly, and improving the versatility and stability of the device.
[0028] A protective shell 20 is fixedly installed at the upper center of the turntable 2. The drive rod 18 is located inside the protective shell 20. A storage box 4 is fixedly installed at the bottom of the base 1. Multiple tool boxes 5 are slidably installed inside the storage box 4. The integrated design of the storage box 4 at the bottom of the base 1 and the sliding tool boxes 5 provides a classified storage space for disassembly tools. Operators can quickly access the tools they need, optimize the maintenance process, and improve the convenience and standardization of on-site operations.
[0029] Working principle: In actual use, first place the gear reducer to be disassembled stably in the middle of the turntable 2. Then, start the servo motor 8. The servo motor 8 drives the cam 9 to start rotating. Due to the special contour curve design of the cam 9, during its rotation, it will drive the connecting rods 10 at both ends to move. The movement of the connecting rods 10 will push the clamping plate 13 to slide along the slide rail 11, thereby realizing the opening and closing action of the clamping plate 13. The operator can flexibly control the servo motor 8 according to the actual size of the gear reducer components, so that the clamping plate 13 can move quickly and accurately to the appropriate position and tightly clamp the gear reducer. In conjunction with the rotary motor 3 driving the turntable 2 to rotate, the angle of the reducer can be adjusted, which facilitates the disassembly of components at different positions of the reducer.
[0030] Next, the forward and reverse motor 17 is started. The forward and reverse motor 17 drives the drive rod 18 to rotate, and the drive gear 19 on the drive rod 18 rotates accordingly. The drive gear 19 meshes with the semi-circular gear 16. Through this meshing transmission, the opening and closing angle of the two clamping seats 7 can be dynamically adjusted. The operator can precisely adjust the opening and closing angle between the two clamping seats 7 according to the size and specifications of the gear reducer, so that they can perfectly fit the part of the gear reducer to be disassembled.
[0031] When it is necessary to release the clamped part, simply start the servo motor 8 in reverse, so that the cam 9 rotates in reverse, which in turn drives the connecting rod 10 to move in reverse, and finally allows the clamping plate 13 to slide in reverse along the slide rail 11, thus realizing the operation of quickly releasing the part.
