[0002] Solid metal wheels are widely used in heavy machinery and equipment, logistics and transportation, agricultural machinery and other fields due to their high load-bearing capacity, service life and reliability. They provide better support and stability, improve transportation efficiency and safety, and ensure the normal operation of machinery. The metal wheel is a long metal cylinder before the production process. The surface needs to be polished to a certain size first, and then cut to the appropriate width.

[0003] However, the above device still has the following problems during implementation:

[0004] The existing technology makes the metal wheel a long metal cylinder before the production process. The surface needs to be polished to a certain size first and then cut to a suitable width.

The polishing disc can be fixed by rotating the polishing disc and combining its thread with the corresponding thread on the equipment. However, the thread is prone to wear. When the polishing disc is frequently disassembled and replaced, it is easy to slip and loosen. Therefore, a polishing device for metal wheel production is specially proposed to solve the above problems. Utility Model Content

Positioning is performed, and then the grinding disc 4 is picked up to drive the special-shaped hole 9 to dock with the special-shaped rod 3. When the grinding disc 4 contacts the limiting plate 11, the docking block 72 can be aligned with the docking groove 10. Then, the push rod 82 is pulled to drive the matching plate 81 back to its original position. The movement of the matching plate 81 will drive the extrusion plate 13 back to its original position, and the spring 73 will undergo elastic deformation to drive the moving block 71 back to its original position. The movement of the moving block 71 will drive the docking block 72 to penetrate the mounting groove 5 and extend to the inner cavity of the docking groove 10. At this time, the position of the grinding disc 4 can be fixed.
