Workpiece grinding machine of numerical-control electric spark machine tool

Abstract

The invention relates to a workpiece grinding machine of a numerical-control electric spark machine tool. The workpiece grinding machine of the numerical-control electric spark machine tool comprisesa base plate, a fixing device, an inner wall grinding device and an outer wall grinding device. The fixing device and the inner wall grinding device are sequentially installed on the base plate from left to right. The outer wall grinding device is installed on the back side of the base plate. The inner wall grinding device comprises a fixing plate, a rotating motor, a rotating column, sliding blocks, limiting frames, telescopic rods, springs, adjusting air cylinders and first steel wire brushes. The outer wall polishing device comprises a lifting frame, a rotating motor, a rotating column, a cam, connection sliding blocks, connection frames, guide rails and second steel wire brushes. The workpiece grinding machine of the numerical-control electric spark machine tool can solve the problemsthat in an existing annular workpiece grinding process, the labor cost is high, the labor intensity is high, the work efficiency is low, the grinding difficulty is large, and the adjustability is poor; the automatic grinding function on the annular workpiece can be achieved; and the workpiece grinding machine of the numerical-control electric spark machine tool has the advantages of being low in labor cost, low in labor intensity, high in work efficiency, small in polishing difficulty, good in adjustability and the like.

Description

technical field [0001] The invention relates to the field of workpiece grinding equipment, in particular to a CNC electric discharge machine tool grinding machine. Background technique [0002] EDM machine tool, also known as CNC EDM machine tool, EDM, spark machine, etc., is a kind of electrical processing equipment. When the Lazarinko couple in the former Soviet Union studied the phenomenon and causes of the damage of the switch contacts by spark discharge corrosion, they found that the instantaneous high temperature of the electric spark could melt and oxidize the local metal and be corroded, thus creating and inventing the electric discharge machining method . After the workpiece is processed by an EDM machine tool, the inner and outer walls of the workpiece tend to become rougher, which affects the surface properties of the workpiece, so the inner and outer walls of the workpiece need to be polished afterwards. At present, the grinding of ring-shaped workpieces is mai...
