Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In order to solve the problem that the grinding block itself is a consumable and is easily worn out during the polishing process, it needs to be replaced frequently. The traditional bolt structure is troublesome to disassemble and takes a long time, which will affect the overall production efficiency. Please refer to Figure 1-3 , the utility model provides the following solutions:

[0020] A horseshoe-shaped sponge polishing block that is easy to replace, comprising a sponge polishing block 1 and a polishing block sleeve 2, wherein the sponge polishing block 1 is fitted and connected to the polishing block sleeve 2, an inner locking hole 101 is arranged inside the sponge polishing block 1, an expansion rubber sleeve 3 is arranged inside the inner locking hole 101, an integrated joint plate sleeve groove 201 is arranged on the inner surface of the polishing block sleeve 2, a locking bolt 4 is arranged inside the joint plate sleeve groove 201, one end of the expansion rubber sleeve 3 extends to the inside of the joint plate sleeve groove 201, and the locking bolt 4 extends to the inside of the expansion rubber sleeve 3;

[0021] In this embodiment, the locking bolt 4 passes through the joint plate sleeve groove 201 and is connected with the soft rubber piston 402 inside the expansion rubber sleeve 3. Then, the expansion rubber sleeve 3 equipped with the soft rubber piston 402 is first inserted into the inner locking hole 101 inside the sponge grinding block 1. After the soft rubber piston 402 is inserted, the locking bolt 4 is rotated. By continuously rotating the locking bolt 4, the soft rubber piston 402 can be controlled to move into the expansion rubber sleeve 3. The expansion rubber sleeve 3 is expanded and stretched by the expansion rubber sleeve 3, thereby increasing the friction resistance between the expansion rubber sleeve 3 and the grinding block to complete the fixation. When replacing, after rotating the locking bolt 4 in the opposite direction, the expansion rubber sleeve 3 moves in the opposite direction to reduce the friction resistance between the expansion rubber sleeve 3 and the grinding block. Finally, the grinding block can be pulled out to complete the replacement. The replacement is very convenient in the whole process.

[0022] A conical inner groove 302 is provided inside the expansion rubber sleeve 3, and a plurality of limiting slide grooves 301 are provided on the outer surface of the expansion rubber sleeve 3. A soft rubber piston 402 is provided at one end of the locking bolt 4, and an integrally formed clamping shaft 4022 is provided on the outer side of the soft rubber piston 402. The soft rubber piston 402 is connected to the expansion rubber sleeve 3 through the conical inner groove 302. The conical inner groove 302 can provide different friction resistances during the movement of the soft rubber piston 402. The clamping shaft 4022 is slidably connected to the limiting slide groove 301, and a mounting groove 4021 is provided on one side of the soft rubber piston 402. A hexagonal nut 401 is provided inside the mounting groove 4021. The locking bolt 4 is connected to the hexagonal nut 401 through an internal thread, and the locking bolt 4 is rotatably connected to the grinding block sleeve 2 and the expansion rubber sleeve 3 respectively.

[0023] In this embodiment, the hexagonal nut 401 is first installed in the assembly groove 4021 on the surface of the soft rubber piston 402, and the assembly groove 4021 is used to limit and fix the hexagonal nut 401. Then, a connection is established with the locking bolt 4 through the hexagonal nut 401. When the locking bolt 4 rotates, the hexagonal nut 401 moves back and forth along the thread.

[0024] Working principle: the locking bolt 4 passes through the joint plate sleeve groove 201 and is connected with the soft rubber piston 402 inside the expansion rubber sleeve 3. Then the expansion rubber sleeve 3 equipped with the soft rubber piston 402 is first inserted into the inner locking hole 101 inside the sponge grinding block 1. After the soft rubber piston 402 is inserted, the locking bolt 4 is rotated. By continuously rotating the locking bolt 4, the soft rubber piston 402 can be controlled to move toward the inside of the expansion rubber sleeve 3. The expansion rubber sleeve 3 is expanded and stretched by the expansion rubber sleeve 3, thereby increasing the friction resistance between the expansion rubber sleeve 3 and the grinding block to complete the fixation. When replacing, after rotating the locking bolt 4 in the opposite direction, the expansion rubber sleeve 3 moves in the opposite direction to reduce the friction resistance between the expansion rubber sleeve 3 and the grinding block. Finally, the grinding block is pulled out to complete the replacement.
