过去,在立铣上加工采油树悬挂器上的“O”形圈槽(图1)时,铣工一手转动分度头,一手握进刀手柄进行加工,工效低,工人劳动强度大,而且产品质量往往达不到技术要求。为改变这种加工状况,我们经过反复试验,革新出一套铣“O”形圈槽的胎具。生产实践证明,使用这种胎具,加工效果良好,槽底和两侧光洁度为▽5,能满足装“O”形圈后承受高压密封的要求,工效比以前提高5～7倍,同时大大减轻了工人的劳动强度。采用类似
In the past, when milling the “O” ring groove on the tree hanger (Figure 1) on the vertical milling machine, the milling cutter rotated the indexing head with one hand and the handle in the other hand for machining. The work efficiency was low and the worker was labor-intensive, and the product Quality often can not meet the technical requirements. In order to change this processing situation, we have tried many times to innovate a set of molds for milling “O” ring grooves. Production practice has proved that the use of such a tire, the processing effect is good, the groove bottom and both sides of the finish is ▽ 5, to meet the “O” ring fitted with high pressure seal requirements, the work efficiency increased 5 to 7 times than before, Reduce the labor intensity of workers. Using similar
