Abstract

The invention discloses a grinding component of a centerless grinding machine suitable for machining a step shaft part. The grinding component comprises a grinding wheel, a guide wheel, a grinding wheel finisher guide plate, a guide wheel finisher guide plate and a support plate component, wherein the grinding wheel is a step grinding wheel; the guide wheel is a step guide wheel; working surfaces of the grinding wheel finisher guide plate and the guide wheel finisher guide plate are both step surfaces; and the support plate component comprises an arc surface support plate arranged on a working table for bearing a cylindrical surface of a small-diameter shaft section of the step shaft part, and a plane support plate arranged at one end of the arc surface support plate through a lifting adjusting mechanism for bearing a cylindrical surface of a large-diameter shaft section of the step shaft part. The grinding component has the following beneficial effects: two cylindrical surfaces of the step shaft part are once grinded; and compared with a conventional process, the efficiency is high, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of centerless grinding machines, in particular to a grinding assembly of a centerless grinding machine suitable for processing stepped shaft parts. Background technique [0002] When a stepped shaft part is not allowed to have a center hole at both ends, such as figure 1 As shown in the stepped shaft part 10, the entire shaft length of the stepped shaft part 10 is L1, the length of the large-diameter shaft section 12 is L2, the outer diameter of the small-diameter shaft section 11 is D1, and the outer diameter of the large-diameter shaft section 12 is D2 , in order to ensure the coaxiality requirements, the conventional process of external cylindrical grinding needs to reserve process benchmarks. That is: reserve the process bosses at both ends, and then drill the center holes on the bosses at both ends as the process benchmark of cylindrical grinding. After the grinding is completed, the bosses at both ends need to...
