Technical Field

The invention relates to the technical field of polishing of inner walls of circular tubes, in particular to a polishing device for the inner walls of the circular tubes for machine manufacturing.

Background

Polishing refers to a process of reducing the roughness of the surface of a workpiece by mechanical, chemical or electrochemical action to obtain a bright, flat surface. The method is to modify the surface of a polished workpiece by using a polishing tool and abrasive particles or other polishing media, wherein polishing cannot improve the dimensional accuracy or geometric accuracy of the workpiece, but aims to obtain a smooth surface or mirror surface polishing, and sometimes is used for eliminating gloss. Grinding wheels are commonly used as grinding tools. The grinding wheel is generally made of a plurality of layers of grinding canvas, grinding felt or leather, the two sides of the grinding wheel are clamped by metal circular plates, and the rim of the grinding wheel is coated with a grinding agent which is formed by uniformly mixing micro-powder grinding materials, grease and the like.

Through search, chinese patent publication No. CN206550766U discloses an efficient automatic grinding machine for inside and outside of a circular tube, and one of the above patents has the following disadvantages: the grinding mode of the inner wall of the circular tube is that a grinding roller is driven by a motor to grind the inner wall of the circular tube, and the grinding roller moves transversely by using another lifting mechanism, so that the matching degree among a plurality of mechanisms is poor, the energy consumption is high, and the working strength of people is improved; simultaneously, in the process of polishing the inner wall of the circular tube by the polishing roller, the polishing roller is clamped on the inner wall of the circular tube and cannot be pulled out due to expansion caused by heat and contraction caused by cold, so that great inconvenience is brought to polishing work of people. Therefore, a grinding device for inner wall of circular tube for machine manufacturing is needed to solve the above problems.
