[0023] This utility model provides a fixture for machining motor shafts, the structure of which is as follows: Figures 1-4As shown, the device includes a workbench 1, with a side plate 2 fixed to the top of the workbench 1. The side plate 2 has several sliding slots 3 and a ring plate 5. Sliding rods 4 are slidably connected to each of the sliding slots 3. A moving block 6 is fixed to one end of each of the sliding rods 4, and a moving rod 7 is fixed to the other end. A first connecting block 8 is fixed to the inner side of each of the moving blocks 6. Each of the first connecting blocks 8 is movably connected to a drive rod 10 via a first rotating shaft 9. A ring 13 is fixed to the side of the ring plate 5 via several connecting rods 12, and several second connecting blocks 11, the same number as the drive rods 10, are fixed to its outer arc. The second connecting blocks 11 are movably connected to the other end of the drive rods 10 via a second rotating shaft 14. Several evenly distributed racks 15 are fixed to the outer arc of the ring 13. Grooves 19 are opened on the inner side of each of the moving rods 7, and one end of each is fitted with a... The device is equipped with a first motor 20, the output end of which extends into a groove 19 and is connected to a screw 21. A limiting block 22, adapted to the groove 19, is threaded onto the side of the screw 21. Several limiting blocks 22 are each fixed to the inner side of a first cylinder 23, the piston rod of which is connected to a clamping plate 24. A second motor 16 is mounted on the side of the side plate 2, its output end connected to a gear 17 meshing with several racks 15. The output ends of the first motors 20 drive the screw 21 to rotate, moving the clamping plates 24 to suitable positions. Then, the output ends of the second motors 16 drive the gears 17 to mesh with the racks 15, causing the ring plate 5 to rotate, which in turn drives one end of several drive rods 10 to rotate. Finally, the drive rods 10 drive the clamping plates 24 inward via a slide rod 4, thus clamping and securing the motor shaft. Using a motor shaft machining fixture is flexible, allowing the size of the fixture to be adjusted according to the diameter of the motor shaft for clamping and securing, making it convenient for workers to operate.

[0024] Furthermore, a second cylinder 25 is also installed on the side of the side plate 2, and its piston rod passes through the side plate 2 and is connected to a support plate 26. A tapered groove 27 is opened on the other side of the support plate 26 to support the motor shaft so as to clamp and fix it.

[0025] Furthermore, the support plate 26 is also connected to the side plate 2 via two telescopic rods 28, which serve as a support.

[0026] Furthermore, two opposing support arc plates 18 are fixed to the side of the side plate 2. The two support arc plates 18 are located on the inner arc of the ring plate 5 and are in close contact with it, which are used to limit the ring plate 5.

[0027] Furthermore, several clamping plates 24 have arc-shaped grooves 29 on their inner sides to improve their clamping effect.

[0028] Furthermore, a bearing 32 is fixed to the side wall of the groove 19. The bearing 32 is connected to the other end of the screw 21 and is used to support the rotation of the screw 21.

[0029] Furthermore, two mounting blocks 30 are fixed on both sides of the workbench 1, and mounting holes 31 are opened on several mounting blocks 30 to facilitate the installation of the workbench 1.

[0030] The working principle of this utility model is as follows: First, several first motors 20 are started, and their output ends drive the screws 21 to rotate, causing several clamping plates 24 to move to a suitable position. Then, the second motor 16 is started, and its output end drives the gear 17 to mesh with several racks 15, causing the ring plate 5 to rotate, which in turn drives one end of several drive rods 10 to rotate. Finally, several drive rods 10 drive the clamping plates 24 to move inward through the slide rod 4, thereby clamping and securing the motor shaft. The size of the clamp can be adjusted according to the diameter of the motor shaft to clamp and fix the motor shaft, making it convenient for workers to operate and use.

[0031] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way.
