Fixture for machining of numerical control electric spark machine tool

Abstract

The invention relates to a fixture for machining of a numerical control electric spark machine tool. The fixture comprises a bottom plate, a clamping device, limiting devices and a cleaning device. The bottom plate is provided with a sliding chute, the sliding chute is internally provided with the clamping device, the front end and the rear end of the clamping device are symmetrically provided with the limiting devices, the limiting devices are installed on the bottom plate, and the rear side of the bottom plate is provided with the cleaning device. The clamping device comprises a first movement mechanism, a second movement mechanism, a rotating mechanism and clamping mechanisms. The clamping mechanisms comprise work round plates, rotating motors, driving gears, driven gears, adjustment pillars, movement plates, fixed clamping plates, telescopic clamping plates and rubber strips. By means of the fixture for machining of the numerical control electric spark machine tool, the problems that in an existing annular workpiece clamping process, work stability is poor, the use range is narrow, adjustment is poor, potential safety hazards exist, and the like can be solved, and the functionof automatically clamping an annular workpiece can be realized.

Description

technical field [0001] The invention relates to the field of fixture equipment, in particular to a fixture for CNC electric discharge machine tool processing. Background technique [0002] EDM machine tool, also known as CNC EDM machine tool, 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 position accuracy with other surfaces specified in the drawing, the workpiece must be positioned and clamped before processing. However, most of the current tooling fixtures can onl...
