Abstract

The invention discloses a workpiece clamp for numerical control machine tool machining, and relates to improvement of a machine tool machining auxiliary clamp, in particular to improvement of the workpiece clamp for numerical control machine tool machining. The workpiece clamp comprises a workpiece mounting piece, a connecting piece base and a base connecting piece, the top of the workpiece mounting piece is inserted into the bottom of a machined workpiece, the bottom of the workpiece mounting piece is fixed to the connecting piece base, and the connecting piece base is fixed to a machine toolbody through the base connecting piece; and during use, a base fixing column is inserted into the connecting piece base and is fixedly connected through a center guide column and an expansion ring, and a connecting center shaft is inserted into the machined workpiece. By the adoption of the technical scheme, the workpiece clamp has the advantages that mounting is rapid and convenient, the physical and mechanical characteristics of numerical control machining are utilized, and therefore the assembling rapidness and the machining stability can be guaranteed; and through assembling of the base,the clamping universality can be guaranteed, the cost of the tool clamp is greatly reduced, the clamping period of the workpiece can be shortened, and the working efficiency of the machine tool is improved.

Description

technical field [0001] The invention relates to an improvement of a machining auxiliary jig for a machine tool, in particular to an improvement of a workpiece jig for a numerically controlled machine tool. Background technique [0002] CNC EDM is a machining process that mainly uses a discharge electrode with a specific geometric shape to burn out the geometric shape of the electrode on a metal part. The characteristics of CNC EDM are: CNC EDM technology is often used in the production of blanking dies and casting moulds. There is no direct contact between the tool electrode and the workpiece, but a spark discharge gap. This gap is generally between 0.05~0.3mm, and sometimes it may reach 0.5mm or even larger. The gap is filled with working fluid. Pulse discharge, discharge corrosion on the workpiece. Since the removal of materials during processing is realized by the electric and thermal effects of discharge, the machinability of materials mainly depends on the electrical ...
