Electric spark machine tool grinding equipment for annular workpiece

Abstract

The invention relates to electric spark machine tool grinding equipment for an annular workpiece. The electric spark machine tool grinding equipment comprises a bottom plate, a fixing device and an inner wall grinding device, wherein the fixing device and the inner wall grinding device are sequentially arranged on the bottom plate from left to right; the inner wall grinding device comprises a fixing plate, a rotating motor, a rotating column, a sliding block, a limiting frame, a telescopic rod, a spring, an adjusting air cylinder and a first steel wire brush; and the fixing device comprises alinear guide rail, an electric sliding block, a sliding plate and a fixing mechanism. According to the electric spark machine tool grinding equipment, the problems that in the existing annular workpiece grinding process, the manual cost is high, the labor intensity is large, the working efficiency is low, the grinding difficulty is large, the adjustability is poor and the like are solved, the automatic grinding function of the annular workpiece can be realized, and the electric spark machine tool grinding equipment has the advantages of being low in manual cost, small in labor intensity, highin working efficiency, small in grinding difficulty, good in adjustability and the like.

Description

technical field [0001] The invention relates to the field of workpiece grinding equipment, in particular to an electric discharge machine grinding equipment for circular workpieces. 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 the EDM machine tool, the inner wall of the workpiece tends to become rough, which affects the performance of the workpiece, so the inner wall of the workpiece needs to be polished afterwards. At present, the grinding of ring-shaped workpieces is mainly carrie...

AI Technical Summary

Problems solved by technology

[0003] In order to make up for the deficiencies in the prior art, the present invention provides an EDM grinding equipment for ring workpieces, which can solve the problems of high labor cost, high labor intensity, low work efficiency and difficulty in grinding existing in the grinding process of ring workpieces. Large size and poor adjustability, etc., can realize the function of automatic grinding of ring-shaped workpieces, with the advantages of low labor cost, low labor intensity, high work efficiency, small grinding difficulty and good adjustability, etc.
