在测量螺旋角时,即在仪器右前方控制板上揿下投影屏照明钮 M,照明灯燃亮,按测量长度α调整安装在高精度球轴承上的垂直拖板时,压花调节手轮(以下简称手轮)失灵。本文就这一故障的检修,谈谈个人的体会,以供参改。一、故障检查一般来说,照明灯燃亮,则仪器电源供电正常;如按下相应的测量钮时,该仪的下主轴能回转以及在全长60毫米范围内上、下移动,那末打开仪器左前面上、下两个盖板,检查导致手轮失灵的可
In the measurement of the helix angle, that is, in front of the instrument on the control panel 揿 down projection screen illumination button M, the lights lit, according to the measurement of the length of the α adjustment precision vertical ball bearings mounted on the carriage, the embossing adjustment hand wheel (Hereinafter referred to as handwheel) failure. This article on the maintenance of this failure, talk about personal experience for the reform. First, the fault check In general, the lights lit, the instrument power supply is normal; If you press the appropriate measuring button, the instrument can rotate under the spindle and the full length of 60 mm range up and down, then open The left front of the instrument, the next two cover, check the hand wheel can lead to failure
