Embodiment Construction

[0010] See figure 1 ,2. The present invention is mainly composed of a motor 1, a supporting frame 2, a coupling 5, an elongated shaft 6, an electrode mounting seat 7, an electrode 8, and a rectangular copper block 12.

[0011] During EDM processing, the working fluid enters through the inner punching hole 10 on the electrode mounting seat 7, flows through the inner punching hole on the electrode 8, and then flows out through the surface of the workpiece 13 to complete the punching. The elongated shaft 6 is driven to rotate by the electric motor 1, the elongated shaft 6 and the electric motor 1 are connected by a coupling 5, and the elongated shaft 6 is radially positioned by a bearing 9. The end of the elongated shaft 6 is connected to the rectangular parallelepiped copper block 12 through threads, and the bottom of the rectangular parallelepiped copper block 12 is flush with the bottom of the electrode 8. In addition, there are two symmetrical brush holes 11 on the electrode mo...

Abstract

The invention belongs to the field of machining, and relates to a synchronous processing mechanism for parts at fluid filling hole positions for electrical discharge machining. The synchronous processing mechanism mainly comprises a motor 1, a support frame 2, couplings 5, a spindly shaft 6, an electrode mounting base 7, an electrode 8 and a cuboid copper block 12. During electrical discharge machining, the motor 1 drives the spindly shaft 6 to rotate so as to drive the cuboid copper block 12 on the end part to rotate, the cuboid copper block 12 and the electrode 8 are isopotential, and the cuboid copper block 12 participates in electrical discharge machining of a workpiece 13 at a fluid filling hole position, and the normal fluid filling for the electrical discharge machining is not influenced.

Description

Technical field [0001] The invention belongs to the field of mechanical processing, and relates to a synchronous processing mechanism of a workpiece at a punching hole position for electric spark forming processing. [0002] technical background [0003] In the EDM forming process of water-based working fluid, an inner punching hole is opened in the center of the electrode, which is the need for punching in the machining process. However, during the EDM machining process, the workpiece at the punching hole at the center of the electrode cannot be processed, so there will always be a small punching boss that cannot be machined by the electrode on the workpiece, which affects the processing quality of the workpiece. Summary of the invention [0004] The purpose of the present invention is to provide a synchronous machining mechanism for the workpiece at the punch hole position for EDM machining. In order to realize the synchronous removal of workpieces in the punching hole parts that...
