[0003] After searching, the China Patent Network has disclosed a diameter measuring device for large-diameter shaft-disk type workpieces, and its authorization announcement number is CN220829158U. The patent places the workpiece to be tested on the top of the bridge ruler body, and drives the threaded rod to rotate by rotating the locking knob. During the rotation of the threaded rod, the locking clamp plate is driven to move downward, which is convenient for fixing the workpiece to be tested. The workpiece can be fixed to prevent displacement during the measurement process, thereby ensuring the accuracy of the measurement data; in addition, by moving the slider, the sliding block drives the movable plate and the pointer to move.
