Parallel indexing cam finish machining device and method

Abstract

The invention discloses a parallel indexing cam finish machining device. The parallel indexing cam finish machining device is used for solving the problem that machining precision is not high. The parallel indexing cam finish machining device comprises a box body, an index plate fixing and adjusting assembly, an index plate and a parallel indexing cam shaft positioning assembly. Oil fluid and abrasive material mixture are contained in an inner cavity of the box body, the two ends of the index plate are fixed in the index plate fixing and adjusting assembly through a bearing, and the index plate fixing and adjusting assembly comprises a bearing cover plate, the bearing, a sliding bearing pedestal, a sealing gasket, a positioning screw and a spring ejecting bead mechanism. The parallel indexing cam shaft positioning assembly comprises a bearing assembly, a gasket and a bearing end cover. The two side walls of the box body are provided with shaft holes parallel to the index plate. The bearing assembly, the gasket and the bearing end cover are sequentially fixed on the side walls, wherein the shaft holes are formed, of the box body. The invention further provides a parallel indexing cam finish machining method. According to the parallel indexing cam finish machining device and method, abrasive machining is conducted through contact among a parallel indexing cam, a roller and abrasive materials with the adoption of the generating cutting principle, the value of surface roughness Ra can be 0.01micrometer.

Description

technical field [0001] The invention relates to the technical field of parallel indexing cam finishing, in particular to a parallel indexing cam finishing method, and provides a parallel indexing cam finishing device. Background technique [0002] Parallel indexing cam transmission mechanism is often used in automation equipment, which has high requirements for shape, size and surface quality, and needs to be finished. In order to improve the motion accuracy, wear resistance and service life of the parallel indexing cam, it is necessary to quench the parallel indexing cam to increase its hardness. The finishing of the parallel indexing cam is completed after quenching. According to the principle of cutting, better tool materials are required for processing high-hardness materials. Therefore, the finishing of the parallel indexing cam after quenching requires superhard tools, and the tool cost is high. The commonly used parallel indexing cam finishing method cannot be comple...

AI Technical Summary

Problems solved by technology

The finishing of the parallel indexing cam is completed after quenching. According to the principle of cutting, better tool materials are needed for processing high hardness materials. Therefore, the finishing of the parallel indexing cam after quenching requires superhard tools, and the tool cost is high.

The commonly used parallel indexing cam finishing method cannot be completed with ordinary tools and ordinary processing parameters, so milling is often used instead of grinding finishing, and the surface quality of milling is not high
