在л3-15超精机上用砂布(或砂带)超精圆锥或短圆柱滚子轴承内滚道时,超精头要不断上下升降,以便更换砂布(或砂带)的工作面,并且超精头还要以一定的压力压向加工表面,来完成超精加工。在原来的机床上超精头的这些动作是靠操作者手动完成。因而操作工人的体力劳动强度很大,并且由于人工施加压力不稳定,而反映出加工表面质量也不够稳定。 目前,磨工车间在这种超精机的超精头上安装了一种专门设计的双径气缸代替了原来的手动操作,效果很好,气压超精装置(见附图)的工作原理如下。
In л3-15 super-precision machine with emery cloth (or belt) super-cone or short cylindrical roller bearing inner raceway, the super-precision to keep up and down in order to change the emery cloth (or belt) face, and super Precision head but also to a certain pressure on the processing surface, to complete the super-finishing. In the original machine super-precision these actions are done manually by the operator. As a result, the manual labor intensity of the workers is very high, and because of the instability of manual pressure, the quality of the processed surface is not stable enough. At present, the grinding shop installed a specially designed dual-diameter cylinder on the superfinishing machine of this super-precision machine to replace the original manual operation, and the effect is very good. The working principle of the pneumatic superfinishing device (see attached drawing) is as follows .
