我厂自行设计的万能角度尺圆度刻线机制造成功。据我们了解目前国内现有的圆度刻线机(包括进口的)均采用蜗轮和蜗杆的传动来完成,在结构上比较复杂,零部件的制造和配合要求精度很高,其中的关键件蜗轮、蜗杆和齿轮等都要求“0”级精度。我们却采用了棘轮、棘爪拨齿传动、靠定位轮定位来进行精密分度的新结构,即由多精件组合传动转为单精件定位分度。经过长期使用证明:这台万能角度尺刻线机完全可以达到较高的精度,且结构简单,制造较易,调整操作方便,稳定性好。其结构见示意图1。回转盘1上装有精密定位齿盘2和棘齿盘3。电机通过变速后,带凸轮5和凸轮6转动、凸轮6拨动杠杆,通过滑块移 I plant self-designed universal angle ruler engraving machine made success. According to our understanding of the current domestic roundness marking machine (including imported) are used worm gear and worm drive to complete the more complex structure, parts manufacturing and matching requirements of high precision, of which the key parts of the worm , Worm and gear all require “0” level accuracy. We have adopted a ratchet, pawl gear transmission, positioned by the positioning wheel for precision indexing of the new structure, that is, from the combination of multi-precision components into a single fine positioning indexing. After long-term use of proof: This universal angle ruler engraving machine can achieve high accuracy, and the simple structure, easy to manufacture, easy adjustment, good stability. See the schematic diagram of its structure. The turntable 1 is provided with a precision positioning toothed disk 2 and a toothed disk 3. After the motor speed is changed, the cam 5 and the cam 6 rotate, the cam 6 pushes the lever and moves through the slider
