Tool clamp for EDM machine tool

Abstract

The invention relates to a tool clamp for an EDM machine tool. The tool clamp comprises a bottom plate and a clamping mechanism, wherein a sliding groove is formed in the bottom plate, and a clampingdevice is installed in the sliding groove; and the clamping device comprises a first moving mechanism, a second moving mechanism, a rotating mechanism and clamping mechanisms, wherein the rotating mechanism comprises a mounting frame, a rotating motor, a supporting frame, a rotating frame and a rotating column, and the clamping mechanisms comprise working round plates, rotating motors, driving gears, driven gears, adjusting columns, moving plates, fixed clamping plates, telescopic clamping plates and rubber strips. According to the tool clamp for the EDM machine tool, the problems that duringthe clamping process of an existing annular workpiece, the working stability is poor, the application range is small, and adjustability is poor can be solved, the function of carrying out automatic clamping on the annular workpiece can be achieved, and the advantages of being high in working stability, wide in application range, flexible to adjust and the like are achieved.

Description

technical field [0001] The invention relates to the field of fixture equipment, in particular to a fixture 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) before processing. . However, ...
