比较精密的内螺纹在工厂中一般都是使用螺纹塞规检查.这种检查方法由于要将塞规拧进拧出,麻烦而费时,而且不能测量出螺纹中径。基辅工学院研制出一种装置,可使工效提高。该装置的下端是手柄11,在手柄上部主体2上装有框架3及固定板5。框架中置有滑块8,滑块与活动式螺纹量头 More sophisticated internal thread in the factory are generally used to check the screw plug.This method of checking because the plug to screw out the screw out, trouble and time-consuming, and can not measure the diameter of the thread. Kiev Institute of Technology developed a device that can improve work efficiency. The lower end of the device is the handle 11, and the frame 3 and the fixing plate 5 are mounted on the handle upper body 2. Set in the framework of the slider 8, slider and movable thread head
