Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0022] Please refer to Figures 1-3 , this utility model provides a technical solution:

[0023] A grinding and clamping device for the production of a motor shaft, including a clamping block 1. On the side wall of the clamping block 1, two symmetrically distributed mounting plates 8 are fixedly connected. At the upper ends of the two mounting plates 8, a scale 9 is fixedly connected. At the upper ends of the two mounting plates 8, a mounting block 10 is fixedly connected. Inside the mounting block 10, a spring 11 is provided. Inside the mounting block 10, a lifting plate 12 is slidably connected. At the upper end of the lifting plate 12, a sliding rod 13 is fixedly connected. At the upper end of the sliding rod 13, a baffle 14 is fixedly connected. On the side wall of the mounting block 10, a sliding groove 16 is opened. Inside the sliding groove 16, a protruding rod 17 is slidably connected.

[0024] Inside the clamping block 1, a clamping groove 2 is opened.

[0025] Exemplarily, the clamping groove 2 facilitates the installation of the motor shaft 5.

[0026] Inside the clamping groove 2, a plurality of telescopic rods 3 distributed in a ring are provided. On the output ends of the plurality of telescopic rods 3, a rubber block 4 is fixedly connected.

[0027] Exemplarily, the plurality of telescopic rods 3 fix the motor shaft 5 at different angles, enabling the device to clamp motor shafts 5 with different diameters.

[0028] The outside of the rubber block 4 contacts the motor shaft 5, and the motor shaft 5 contacts the baffle 14.

[0029] Exemplarily, while clamping the motor shaft 5, the rubber block 4 protects the motor shaft 5 and increases the friction with the motor shaft 5 to maintain the stability of the motor shaft 5.

[0030] On the side wall of the clamping block 1, a first level 6 and a second level 7 are respectively provided.

[0031] Exemplarily, when installing the clamping block 1, observe the first level 6 and the second level 7 to make the clamping block 1 installed on a horizontal plane.

[0032] The protruding rod 17 is slidably connected to the scale 9, and the protruding rod 17 is fixedly connected to the lifting plate 12.

[0033] Exemplarily, according to the position of the protruding rod 17 on the side of the scale 9, read the scale of the scale 9.

[0034] At the upper end of the lifting plate 12, two symmetrically distributed guide rods 15 are fixedly connected. Both of the two guide rods 15 are slidably connected to the mounting block 10.

[0035] Exemplarily, when the lifting plate 12 moves up and down, the guide rods 15 play a guiding role.

[0036] Working principle: When the utility model is in use, when installing the clamping block 1, observe the first spirit level 6 and the second spirit level 7 to make the clamping block 1 installed on a horizontal plane. Place the motor shaft 5 into the inside of the clamping groove 2. First, turn on the lower telescopic rod 3 so that the rubber block 4 at the lower end plays a supporting role for the motor shaft 5. Then turn on the upper telescopic rod 3 so that the upper rubber block 4 and the lower rubber block 4 jointly fix the motor shaft 5. The telescopic rods 3 at multiple different angles can clamp the motor shafts 5 with different diameters, facilitating the device to fix the motor shafts 5 with different diameters.

[0037] The mounting plate 8 mounts components such as the mounting block 10. When the motor shaft 5 is installed, press down the baffle 14. The baffle 14 drives the slide rod 13 and the lifting plate 12 to descend. When the lifting plate 12 ascends and descends, the guide rod 15 plays a guiding role. The lifting plate 12 squeezes the spring 11, and the spring 11 is compressed under force. At the same time, the spring 11 has an upward elastic force on the lifting plate 12 to make the baffle 14 stick to the lower end of the motor shaft 5. The lifting plate 12 drives the protruding rod 17 to slide inside the chute 16. According to the position of the protruding rod 17 on the side of the scale 9, read the scale of the scale 9. Keeping the two scales consistent can keep the motor shaft 5 horizontal.

[0038] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
