Abstract

The invention relates to annular workpiece clamping equipment for an electrical discharge machine tool. The annular workpiece clamping equipment comprises a bottom plate, a clamping device and limiting devices, wherein a sliding chute is formed in the bottom plate, the clamping device is installed in the sliding chute, the limiting devices are symmetrically arranged at the front end and the rear end of the clamping device, and the limiting devices are mounted on the bottom plate; the clamping device comprises a first moving mechanism, a second moving mechanism, a rotating mechanism and a clamping mechanism; each limiting device comprises a limiting plate, limiting supporting plates, limiting air cylinders and limiting frames; and the clamping mechanism comprises a circular working plate, arotating motor, a driving gear, a driven gear, adjusting columns, moving plates, fixed clamping plates, telescopic clamping plates and rubber strips. The annular workpiece clamping equipment can solve the problems of poor working stability, a small use range and poor adjustability existing in the clamping process of existing workpieces, can realize the function of automatically clamping the annular workpieces, and has the beneficial effects of being high in working stability, wide in use range, flexible to adjust and the like.

Description

technical field

[0001] The invention relates to the field of fixture equipment, in particular to an annular workpiece clamping equipment for electric discharge machine tools. 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 . When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and mutual position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) be...
