The overall idea is as follows:

[0022] In view of the problems existing in the prior art, the utility model provides a polishing wheel mounting shaft which can prevent deformation, the polishing wheel mounting shaft comprising a fixed cylinder 1, a mounting cone 17 is fixedly mounted on the top of the fixed cylinder 1, a tightening plate 12 is movably mounted on the top of the mounting cone 17, one end of the fixed cylinder 1 is used to connect the polishing equipment, a polishing wheel is mounted on one end of the tightening plate 12, a positioning step is provided at one end of the connecting equipment for limiting the longitudinal position of the polishing wheel, a cross-shaped groove is provided on the top of the top holding block 13, a top holding block 13 is provided on the top of the tightening plate 12, a protrusion 15 is fixedly mounted on the top of the mounting cone 17, a polishing wheel body 11 is rotatably mounted on the side end of the fixed cylinder 1, the polishing wheel body 11 and the fixed cylinder 1 are designed in sections, and the size of the polishing wheel body 11 is smaller than that of the fixed cylinder 1, and a cross opening 18 is provided on both side ends of the mounting cone 17, and the cross opening 18 extends downward from the thread groove 19 and is V-shaped. The design is that a thread groove 19 is provided on the inner side of the mounting cone 17, and the thread groove 19 is designed to spiral downward on the inner side of the mounting cone 17. By moving the tightening plate 12, the threaded rod at the bottom end of the tightening plate 12 is aligned with the top end of the mounting cone 17, and the tightening plate 12 is connected to the mounting cone 17 through the thread groove 19. At the same time, an introduction cone 16 is installed on the top end of the mounting cone 17, and a supporting structure matching the conical thread is provided on the top end of the mounting cone 17. By rotating the tightening plate 12, the threaded rod is driven to rotate inside the mounting cone 17. A thread groove 19 is provided inside the mounting cone 17, which cooperates with the threaded rod to apply a force to the protrusion 15. Since a cross opening 18 is provided on both sides of the protrusion 15, the protrusion 15 is expanded, thereby compensating for the deformation of the polishing wheel body 11, and applying a radial force to the polishing wheel body 11, so that the polishing wheel body 11 remains in a slightly tightened state, and the top of the protrusion 15 is fixedly installed with an introduction cone 16.

[0023] Working principle:

[0024] In the first step, this device is mainly used for polishing soft materials. The polishing wheel body 11 should have a certain elasticity. The end of the fixing tube 1 is fixed to the polishing device by a clamping method. The polishing wheel body 11 is connected to the top of the tightening plate 12. The top of the top holding block 13 is provided with a cross-shaped groove, which extends to the conical bottom near the positioning step. The center of the cross-shaped groove is provided with a conical threaded hole. At the same time, the bottom end of the tightening plate 12 is fixedly installed with a threaded rod. By moving the tightening plate 12, the threaded rod at the bottom of the tightening plate 12 is connected to the mounting cone 1. 7, the tightening plate 12 is connected to the mounting cone 17 through the threaded groove 19, and the top of the mounting cone 17 is installed with an introduction cone 16, and the top of the mounting cone 17 has a supporting structure that matches the tapered thread. By rotating the tightening plate 12, the threaded rod is driven to rotate inside the mounting cone 17. The interior of the mounting cone 17 is provided with a threaded groove 19, which cooperates with the threaded rod to apply force to the protrusion 15. Since the two sides of the protrusion 15 are provided with a cross opening 18, the protrusion 15 is expanded, so that the protrusion 15 squeezes and supports the inner side of the polishing wheel body 11.

[0025] In the second step, the protrusion amplitude of the supporting block 13 can be controlled within a certain range by the depth of the screw-in thread, thereby compensating for the deformation of the polishing wheel body 11 and applying a radial force to the polishing wheel body 11 to keep the polishing wheel body 11 in a slightly tightened state, ensuring that the polishing wheel body 11 is in contact with the workpiece evenly up and down when polishing the workpiece, ensuring the consistency of the polishing surface of the workpiece, and avoiding scratches and uneven polishing caused by the deformation of the polishing wheel body 11. There is a tightening plate 12 between the supporting block 13 and the polishing wheel body 11, and the tightening plate 12 is connected to the bottom end of the supporting block 13 by a thread. By rotating the tightening plate 12, the polishing wheel body 11 is subjected to a clamping force in the axial direction to support the polishing wheel body 11 and reduce deformation.

[0026] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
