Abstract

The invention discloses a self-centering electrolysis grinding combined machining device for an inner hole. The device comprises a cathode arranged in the inner hole of a workpiece, cathode rollers are installed on the outer edge of the cathode, an arc-shaped cathode groove is formed in the cathode, spring pieces are arranged in the cathode groove, one end of each spring piece extends into the cathode groove in an embedded mode, and the other ends of the spring pieces are arranged on clamping claws. One end of each clamping claw is movably connected to the cathode, and the other end of each clamping claw is connected with a clamping claw roller. The radius of the clamping claw rollers is larger than that of circular arcs at the ends of the clamping claws. Two threaded holes are formed in the cathode, the cathode penetrates through the threaded holes and is fixed to an insulating plate outside the workpiece through fixing bolts, a key groove is formed in the insulating plate, the fixing bolts penetrate through the key groove, and the width of the key groove is larger than the nominal diameter of the fixing bolts. The cathode rollers guaranteed the electrolysis gap between the cathode and the workpiece, so that self-centering clamping and electrolysis gap self-adjusting on the inner hole of the workpiece are achieved in the electrolysis grinding process, production efficiency and machining precision are improved substantially, and the surface roughness of the workpiece is decreased.

Description

technical field [0001] The invention relates to a composite processing device, in particular to a composite processing device for self-centering inner hole electrolysis grinding. Background technique [0002] With the increasing demand for various high-strength, high-hardness and high-wear-resistance materials in modern manufacturing technology, improving productivity and processing accuracy, reducing surface roughness and extending the service life of high-strength, high-hardness and high-resistance materials The inevitable development of advanced manufacturing technology. [0003] Electrolytic grinding is suitable for grinding various high-strength, high-hardness, heat-sensitive, brittle and other difficult-to-grind metal materials. Electrolytic grinding technology can significantly improve productivity and processing accuracy, reduce the surface roughness of the workpiece, reduce the residual stress on the processed surface, and the wear of the grinding wheel is small, s...
