All-electric digitization two-freedom-degree force control grinding head device

Abstract

The invention belongs to the technical field of intelligent machining and manufacturing and discloses an all-electric digitization two-freedom-degree force control grinding head device. The all-electric digitization two-freedom-degree force control grinding head device is used for grinding and polishing complex curved surface parts. The all-electric digitization two-freedom-degree force control grinding head device comprises a two-freedom-degree servo platform, a force sensor, a grinding head motor, a grinding head and a control assembly. The force sensor is connected with the two-freedom-degree servo platform and the grinding head motor. The grinding head is connected to the grinding head motor. The control assembly is connected to the force sensor, the grinding head motor and the two-freedom-degree servo platform. The all-electric digitization two-freedom-degree force control grinding head device is high in automation degree, low in cost, high in machining efficiency and relatively high in flexibility, the machining deformation of the workpieces and the stress concentration of a machining area can be reduced, and nonuniformity of polishing is avoided.

Description

technical field [0001] The invention belongs to the technical field of intelligent processing and manufacturing, and more specifically relates to an all-electric numerical two-degree-of-freedom force-controlled grinding head device. Background technique [0002] In the fields of aerospace, automobiles, ships, etc., many core parts have complex surfaces, which cannot be composed of elementary analytical surfaces. Therefore, efficient and high-quality processing of complex surfaces has always been a difficult problem in domestic and foreign manufacturing. [0003] At present, manual grinding is mainly used for finishing free-form surfaces, but this method is labor-intensive, has low processing efficiency, uneven grinding and polishing allowances, and the surface consistency of parts is greatly affected by the technical proficiency of workers. In the actual work process, skilled workers use test samples to plan the grinding and polishing allowance and evaluate the quality of gr...

Problems solved by technology

[0003] At present, manual grinding is mainly used for finishing free-form surfaces, but this method is labor-intensive, has low processing efficiency, uneven grinding and polishing allowances, and the surface consistency of parts is greatly affected by the technical proficiency of workers.

In the actual work process, skilled workers use test samples to plan the grinding and polishing allowance and evaluate the quality of grinding and polishing. The sample detection efficiency is low and the versatility is poor.
