[0021] Example

[0022] See also Figures 1 to 4 The present invention provides a kind of fixture for gear processing, comprises a base 1, a rotating motor 2 is arranged on the left side of the top of the base 1 through a supporting plate, a rotating shaft 3 is arranged on the power output shaft of the rotating motor 2 through the motor, a cavity is arranged inside the rotating shaft 3, a plurality of telescopic rods 5 are evenly arranged on the inner wall below the cavity, a fixing pin 7 is arranged at the end of the telescopic arm at the top of the telescopic rod 5, a return spring 6 is also sleeved on the outer side of the telescopic rod 5, one end of the return spring 6 is connected with the fixing pin 7, and the other end of the return spring 6 is connected with the rotating shaft 3. When the gear is processed by moving downward, the staff will sleeve the gear on the rotating shaft 3, and then under the action of the fixing pin 7, the gear can be key-fixed, thereby ensuring that the gear and the rotating shaft 3 can rotate coaxially, thereby facilitating the staff to process the gear, and a limit plate 4 is also arranged on the right side of the fixing pin 7 on the rotating shaft 3. Under the action of the limit plate 4, the gear can be restricted, thereby ensuring the subsequent processing quality of the gear.

[0023] A mounting shell 8 is also provided on the top right side of the base 1, and a slider 9 is slidably provided on the mounting shell 8. A threaded rod 10 is also rotatably provided inside the mounting shell 8, and the threaded rod 10 passes through the slider 9 and is threadedly connected to the slider 9. At this time, rotating the threaded rod 10 can drive the slider 9 to move left and right on the mounting shell 8. A fixing plate 11 is also provided on the slider 9, and a limiting sleeve 12 is provided on the side wall of the fixing plate 11. Under the action of the limiting sleeve 12 and the fixing plate 11, the gear can be better clamped and fixed, thereby ensuring the clamping and fixing quality of the device for the gear, and facilitating the subsequent processing of the gear.

[0024] A first bevel gear 13 is also provided on the threaded rod 10 on the right side inside the mounting shell 8 through a key connection. A rotating shaft 14 is also rotatably provided inside the mounting shell 8. The first bevel gear 13 is provided on the rotating shaft 14 through a key connection. The second bevel gear 15 is meshed with the first bevel gear 13. The rotating shaft 14 can drive the threaded rod 10 to rotate through the second bevel gear 15 and the first bevel gear 13, and then the fixing plate 11 and the limiting sleeve 12 are used to clamp and fix the gear, thereby ensuring the clamping and fixing quality of the device for the gear.

[0025] A worm gear 16 is also provided on the rotating shaft 14 through a key connection, and a worm 17 is also rotatably provided inside the mounting shell 8. The worm 17 and the worm gear 16 are meshed with each other. At this time, rotating the worm gear 17 can drive the rotating shaft 14 to rotate through the worm gear 16, and then adjust the position of the fixed plate 11 through the threaded rod 10, so that the fixed plate 11 and the limit sleeve 12 clamp and fix the gear. In addition, because the worm gear 16 and the worm gear 17 have a self-locking function, the clamping and fixing quality of the fixed plate 11 for the gear is guaranteed, thereby ensuring the subsequent processing quality of the gear. A motor is also provided inside the mounting shell 8, and the power output shaft of the motor is connected to the worm gear 17 through a coupling, and the worm gear 17 can be driven to rotate by the motor.

[0026] A collecting trough 19 is also provided inside the lower part of the base 1, and a mesh plate 18 is provided on the top of the collecting trough 19. When the staff processes the gears, waste chips will be generated. At this time, the waste chips will enter the collecting trough 19 through the mesh plate 18, thereby completing the collection of the waste chips, reducing the workload of subsequent staff for waste chip collection, and facilitating the cleaning of the working environment.

[0027] In actual use, when the gear needs to be processed, the staff will set the gear sleeve in the rotating shaft 3 and make one side of the gear contact with the limit plate 4. At this time, under the action of the telescopic rod 5, the return spring 6 and the fixing pin 7, the gear can be key-fixed, thereby ensuring that the gear and the rotating motor 2 can rotate coaxially. Then, the starting motor uses the worm 17, the worm wheel 16, the rotating shaft 14, the second bevel gear 15 and the first bevel gear 13 to drive the threaded rod 10 to rotate, so that the fixing plate 11 and the limiting sleeve 12 move to clamp the gear, which is convenient for the staff to process the gear. At the same time, because the worm wheel 16 and the worm 17 have a self-locking function, the clamping quality of the fixing plate 11 and the limiting sleeve 12 for the gear is guaranteed. In addition, a large amount of waste chips will be generated during processing. At this time, the waste chips will enter the collection trough 19 through the grid plate 18, thereby collecting the waste chips and reducing the workload of the staff for subsequent cleaning.
