凸轮平面曲线槽的加工,在一般工厂中采用划线加工方法。这种方法手工操作量大,质量不易达到要求,与一般凸轮相比,其加工比较困难。因为它不仅要求曲线槽两側面具有完全一致的曲线表面,而且在圆周任何部位上的槽宽都应保持相等,以便能使滚子在槽内,按照设计所需要的规律平滑地转动。这里介绍一下,在车床和铣床上用靠模加工凸轮平面曲线槽的方法,供参考。在车床上加工时的装置(图1) 工件(图2)按定位孔用定位销5放入靠模盘1中,并插入安装心轴4,
Cam plane curve groove processing, in the general factory using crossed processing methods. This method of manual operation volume, quality is not easy to meet the requirements, compared with the general cam, the processing more difficult. Because not only does it require that the curvilinear grooves have a perfectly uniform curvilinear surface on both sides, but the groove widths should be kept equal at any part of the circumference so that the rollers rotate smoothly within the groove as the design requires. Here to introduce the use of lathe and milling machine with a cam cam curve plane method for reference. Workpiece in the lathe (Figure 1) The workpiece (Figure 2) according to the positioning hole with the positioning pin 5 into the mold plate 1, and insert the installation mandrel 4,
