西德HS—400型万能测齿仪在安装齿轮时带动上顶针移动的塑料链条很容易断裂.断裂的原因一方面是出于塑料年久老化,主要还是顶针的压力限位开关失灵所造成的.塑料链条是装在与电机连接的齿轮及上顶针螺杆连接的齿轮之间的它起着升降上顶针的作用.链条断后直接影响着仪器的使用.原塑料链条的塑料齿及链之间压有加强多股细钢丝,这种结构制造起来有困难’经过测绘塑料链条及齿轮,设计出如图1形的齿片.我们采用1毫米厚的铜板料,用光电跟踪机床加工出如图1所示的齿片后经过钻孔,(也可采用设计
West Germany HS-400 universal tooth detector in the installation of gears to drive the thimble to move the plastic chain is very easy to break the reason for the fracture on the one hand is out of plastic aging, the main thimble pressure limit switch is caused by the failure The plastic chain is installed between the gear connected with the motor and the gear connected with the upper thimble screw, which plays the role of lifting the upper thimble, which directly affects the use of the instrument.The pressure between the plastic teeth and the chain of the original plastic chain Have to strengthen the multi-strand wire, this structure is difficult to create ’After mapping the plastic chain and gear to design a tooth-shaped Figure 1. We use 1 mm thick copper sheet material, with a photoelectric tracking machine tool shown in Figure 1 After the shown tooth bored, (can also be used design
