Outer circle polishing machine tool

Abstract

The invention is suitable for the field of polishing machine tools, and provides an outer circle polishing machine tool which comprises a bottom plate, a first rotating shaft, a second rotating shaft, a third rotating shaft and a fourth rotating shaft. The fixing assemblies are arranged in the case, and a machined part is arranged between the fixing assemblies; the reciprocating polishing device is arranged in the machine box and used for achieving reciprocating polishing operation on the machined part; the reciprocating polishing device comprises a polishing assembly used for achieving all-directional polishing of the machined part, a polishing assembly used for polishing the machined part and a polishing assembly used for polishing the machined part, the reciprocating assembly is used for driving the reciprocating polishing device to do lifting reciprocating motion; according to the device, the polishing device is modified, the meshing relation between the trapezoidal gears is continuously switched, so that a polishing piece can transversely move in a reciprocating mode, a machined piece is polished, meanwhile, the movement track of the polishing piece is controlled through a guide groove, the large-range all-directional polishing effect is achieved, the polishing effect is better, and the efficiency is higher.

Description

technical field [0001] The invention belongs to the field of polishing machine tools, in particular to an external circular polishing machine tool. Background technique [0002] Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is the modification of the surface of the workpiece by using polishing tools and abrasive particles or other polishing media. [0003] Polishers, 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 a high speed. Because the polishing disc and the polishing agent work together and rub against the surface to be polished, the paint pollution, oxide layer and shallow marks can be removed. Purpose. [0004] Most of the existing polishing machine tools can only polish one part of ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the embodiment of the present invention is to provide a kind of cylindrical polishing machine tool, aiming at solving the problem that most of the existing polishing machine tools can only polish one part of the workpiece when polishing the workpiece. Then adjust the position of the processed or polished piece, and polish other parts. This method is complicated to operate, slow in polishing speed, and low in efficiency.
