Small-size independent biaxial movement structure and polishing machine head adopting same

Abstract

Disclosed is a polishing machine head adopting a small-size independent biaxial movement structure. The polishing machine head comprises a polishing mechanism, a driving mechanism and an independent biaxial mechanism. The polishing mechanism is used for polishing a to-be-processed material piece. The driving mechanism is used for controlling the polishing mechanism to rotate. The independent biaxial mechanism is used for enabling the polishing mechanism to rotate. The driving mechanism is in driving connection with one end of the independent biaxial mechanism. The polishing mechanism is in transmission connection with the other end of the independent biaxial mechanism. The independent biaxial mechanism comprises a first biaxial mechanism, a second biaxial mechanism and a third biaxial mechanism, wherein the third biaxial mechanism is in transmission connection with the second biaxial mechanism, the second biaxial mechanism is in transmission connection with the first biaxial mechanism,and the first biaxial mechanism is in transmission connection with the polishing mechanism. When the small-size independent biaxial movement structure is used in the machine head of a polishing machine, multi-angle rotation of the machine head of the polishing machine can be conveniently controlled, so that the polishing machine can be matched with the curved surface of a special-shaped workpiece, the labor cost is reduced, and the polishing efficiency is improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a polishing machine head. Background technique [0002] Polishing machines, also known as grinders, are often used for mechanical grinding, polishing and waxing. Its working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and friction with the surface to be polished, it can achieve the effect of removing paint surface pollution, oxide layer and shallow marks. Purpose. [0003] Abrasive belt polishing machine is a kind of polishing machine. It is a common mechanical processing equipment that can grind and polish the surface of the workpiece. It is widely used in hardware, plumbing and other industries. The abrasive belt grinding and polishing machine mainly uses the grinding performance of the sand grains on the abrasive belt to grind and polis...

Problems solved by technology

[0005] Although the use of this patent can satisfy the polishing of ordinary workpieces, there are often multiple curved surfaces on the current workpieces that need to be polished. For such special-shaped workpieces, only flat abrasive belts cannot be used for effective polishing. The traditional method is to use The staff manually grind and polish the special curved surface of the workpiece surface, which is not only labor-intensive, time-consuming and labor-intensive, but also the efficiency of grinding and polishing is very low, and the grinding and polishing accuracy of the workpiece surface is not enough
