我厂产品加工中有图1零件,其特点是零件小,尺寸精度、位置精度要求高,最终磨加工装夹定位困难,几次生产,加工精度均不能满足设计要求,关键是四面垂直度0.01mm 及四面对孔对称0.01mm 超差,我们分析原因,经过几次改进,最终设计图2工装,加工出满意产品。利用精度较高的组夹定位块做为工装体,加工一心轴,装于工装体孔中,先将零件内孔磨好,以内孔定位装于心轴一端,按工装体找正方体零件,磨削过
I plant products processing Figure 1 parts, which is characterized by small parts, dimensional accuracy, high position accuracy, the final grinding processing fixture positioning difficulties, several production, processing precision can not meet the design requirements, the key is the verticality of the four sides 0.01 mm and four pairs of hole symmetry 0.01mm tolerance, we analyze the reasons, after several improvements, the final design of Figure 2 tooling, processed out of satisfactory products. The use of high-precision group clamp positioning block as a tooling body, processing a mandrel, installed in the tooling body hole, the first part of the hole grind well, with the hole located at one end of the mandrel, according to Gongzhao body to find the cube parts, grinding Cut
