Technical Field

[0001] The utility model relates to the technical field of speed reducer assembly, in particular to an axial positioning device for speed reducer assembly. Background Technique

[0002] A speed reducer is a component used to adjust the speed and transmit torque between a prime mover and a working mechanism. Speed reducers are widely used in modern mechanical related industries. When assembling a speed reducer, many tools are usually required for manual operation, and the mutual cooperation requirements between internal parts of the speed reducer are relatively high during operation;

[0003] In order to ensure the correct positional relationship of the installed parts during installation, a positioning device is often needed for fixation. Existing devices are all fixed by the cooperation of screws and nuts, and then the parts are tightly fixed before subsequent assembly work;

[0004] For an existing axial positioning device for speed reducer assembly, it is inconvenient to remove the positioning device. Since the device is fixed by bolts, it is necessary to frequently unscrew the bolts when removing the positioning device, which affects the work process. In addition, for an existing axial positioning device for speed reducer assembly, it is not convenient for adaptive clamping. When clamping, due to the use of rigid clamping plates, it is easy to cause wear and extrusion on the surface of the speed reducer or parts after removal. Therefore, an axial positioning device for speed reducer assembly is proposed to solve the above problems. Content of the Utility Model

While the airbag splint clamps the part, due to its own characteristics, the airbag discharges the excess gas during the clamping process with the part according to the shape of the part, thereby achieving the dual effects of protecting and clamping the part and solving the problem that it is inconvenient to adaptively clamp in the prior art.

Through holes 305 are opened in the middle of the first slider 202 in the installation mechanism and in the middle of the outer bottom end of the box body 1. And the positioning rod 303 in the detachable mechanism passes through the through hole 305. The detachable mechanism is used for facilitating the disassembly of the box body 1.

[0031] Refer to Figures 1 - 4, a clamping mechanism is fixedly connected inside the box body 1. The clamping mechanism includes a fixed rod 4. The left and right sides of the inner bottom end of the box body 1 are fixedly connected to the bottom end of the fixed rod 4. The top end of the fixed rod 4 is fixedly connected to an airbag splint 6. A second sliding groove 408 is formed at the rear side of the middle part of the top end of the box body 1. A second slider 407 is slidably connected inside the second sliding groove 408. The bottom end of the second slider 407 is fixedly connected to one end of a connecting shaft 406. The other end of the connecting shaft 406 is fixedly connected to a rack 405. The front and rear sides of the bottom end of the rack 405 are both meshed with a gear 404. A rotating shaft 403 is fixedly connected to the middle of each of the two gears 404. A winding drum 402 is fixedly connected to both the left and right ends of the rotating shaft 403. One end of a cable 401 is fixedly connected to the winding drum 402. The other end of the cable 401 is fixedly connected to another group of airbag splints 6. One end of a spring 409 is fixedly connected to each of the four corners of the top end of the airbag splint 6 inside the top end of the box body 1.

When installing the speed reducer, after sliding the second slider 407, the connecting shaft 406 at the bottom of the second slider 407 drives the rack 405 to move. Since the rack 405 meshes with the gear 404, the gear 404 rotates. The rotating shaft 403 on the rotating gear 404 rotates at the same frequency as the gear 404, causing the cable reel 402 to rotate, retracting the cable 401, and compressing the spring 409. Subsequently, start the air pump 5, and the air pump 5 conveys air from the air inlet pipe 502 to the airbag splint 6 through the air outlet pipe 501. Then place the clamped part between the two airbag splints 6. Subsequently, release the second slider 407, and the spring 409 resets. While the airbag splint 6 clamps the part, due to its own characteristics, the airbag discharges the excess gas during the clamping process with the part according to the shape of the part.
