Description

Technical Field

[0001] The utility model relates to the technical field of grinding and polishing, in particular to a shock-absorbing connecting piece used for handheld grinding and polishing equipment. Background Art

[0002] Polishing is a very important step in the mold making process. With the increasing application of industrial products, the requirements for the appearance quality of industrial products are getting higher and higher. Correspondingly, the polishing quality of the mold cavity surface used to produce industrial products must also be improved accordingly. The processing of the mold surface mainly adopts automated processing. Due to the limitations of the current technical level, some knife marks or hardened layers will remain on the mold surface during processing. After automated processing, the mold cavity surface must be ground and polished to finally obtain the required position accuracy and surface roughness.

[0003] At present, handheld grinding and polishing equipment is mainly used to manually remove knife marks or hardened layers. The handheld grinding and polishing equipment performs polishing operations by controlling the high-speed reciprocating movement of the oil stone. Since the oil stone will generate a large amount of vibration during the high-speed reciprocating movement, it will affect the operator and reduce the grinding accuracy. At the same time, it is not conducive to the operator to use the handheld grinding and polishing equipment for long-term operations.

[0004] Therefore, in view of the deficiencies in the prior art, the utility model designs a shock-absorbing connector for handheld grinding and polishing equipment to solve the above problems.

[0009] The preferred technical solution is that the shock absorbing block has a cylindrical structure, which has a stable shock absorbing effect and is convenient for operators to press the shock absorbing block.

[0010] The preferred technical solution is: the chuck structure is an open groove at the front end of the shock absorbing block, and a clamp is provided on the outer periphery of the open groove. The elasticity of the shock absorbing block itself is used to fix the grinding head with the clamp, so as to facilitate the disassembly and assembly of the grinding head with a flat installation end.

[0011] The preferred technical solution is: the chuck structure is a grinding head mounting seat, the rear end of the grinding head mounting seat is fixedly connected to the front end of the shock-absorbing block, the front end of the grinding head mounting seat is provided with a mounting groove, and the side wall of the mounting groove is provided with fastening bolts, which is convenient for disassembly and assembly of the grinding head with a cylindrical mounting end.
