Numerical control spark machine with high-rigidity machine tool structure

Abstract

The invention relates to the technical field of spark machines, and discloses a numerical control spark machine with a high-rigidity machine tool structure. The numerical control spark machine comprises a spark machine body, a worktable is mounted at the top of a base of the spark machine body, a connecting bracket is mounted at the top of the worktable, and an electrode holder is mounted on the connecting bracket. According to the numerical control spark machine with the high-rigidity machine tool structure, by arranging a toothed plate, a driving wheel, a belt, a driven wheel, a brake ratchet wheel, a brake plate, a fixed support, a lapping plate, a linkage rod, a guide rod, a second spring, a sliding sleeve, a limiting block and a fixed rod, before an electrode is inserted, two movableblocks are far away from a socket, and at the moment, two first springs are compressed; and when the electrode is inserted into the socket, the movable blocks are loosened, clamping blocks can clamp the electrode through transmission of the toothed plate, the driving wheel, the belt, the driven wheel and the like, and the problems that an electrode clamp of an existing numerical control spark machine is unstable in clamping, and the electrode may fall off in the machining process are solved.

Description

technical field [0001] The invention relates to the technical field of spark machines, in particular to a numerically controlled spark machine with a high-rigidity machine tool structure. Background technique [0002] The spark machine is a kind of mechanical processing equipment, which is mainly used for electric discharge machining. Widely used in the manufacture of various metal molds and mechanical equipment. It is a special processing method that uses the electric erosion effect generated by the pulse discharge between the two electrodes immersed in the working fluid to etch the conductive material, also known as discharge machining or electric erosion machining. [0003] At present, the electrode fixture of the CNC spark machine is clamped and installed, and there is a phenomenon of unstable clamping. During the processing, the electrode may fall off.
