为加工8升壳转内曲线液压马达(NKM—8)的定子,我厂在一台废滚齿机上改装成铣磨内曲线机床,加工零件质量符合图纸要求。加工的定子外圆φ730(厚度80),曲线为等加速—等速—等减速(φ_(max)=655,φ_(min)=555),作用数6。加工其他作用曲线的定子,只换凸轮即可。该机床只在通用设备上加几个附件就可使用。其制造简单,上马较快,加工较平稳,便于观察测量。一、结构传动与系统(见图1)1.结构改装
In order to process the stator of NKM-8 with 8L shell, our factory rebuilds the curve milling machine inside a hobbing machine, the quality of the machined parts conforms to the drawing requirements. The outer diameter of the machined stator is φ730 (thickness 80). The curves are equal acceleration - constant speed - equal deceleration (φ max = 655, φ min = 555). Strain processing of other stators, only for the cam can be. The machine only in general equipment plus a few attachments can be used. The manufacture is simple, quick start, processing more stable, easy to observe the measurement. First, the structure of transmission and system (see Figure 1) 1. Structural modification
