在组合机床上使用的回转工作台,大多是用来实现等分转位的。我们在设计加工刹车蹄片铆钉孔倒角机床时,遇到了一个不等分孔的加工问题,被加工零件如图1所示。 我们对被加工零件进行了分析,由于要求的生产率较高,所以确定用多工位机床来加工。为了使机床结构简单可靠,拟定了图2所示的机床方案,对于回转工作台采用液压传动,反靠定位结构。 Rotary table used in the combination of machine tools, mostly used to achieve bisect index. We are in the process of designing brake shoe rivet hole chamfering machine, encountered a unequal hole processing problems, the parts are processed as shown in Figure 1. We analyzed the parts to be machined, and because of the high productivity required, we decided to work with multi-station machines. In order to make the machine tool structure simple and reliable, the machine tool scheme as shown in Fig. 2 has been drawn up. For the rotary table, hydraulic transmission and counter positioning structure are adopted.
