 see figure 1 , figure 2 with image 3 , the front conical hole of the head frame 1 is precisely matched with the head frame thimble 16 as a conical surface, the head frame 1 is fixed on the base 4 with T-shaped screws 8, and the bottom of the base 4 is provided with a leveling foot 5 for adjusting the level of the base 4 The driving rod 15 is fixedly connected to the rotary table 19 through the external thread at the front end, the cylindrical hole on the upper surface of the shifting fork 14 is in clearance fit with the driving rod 15, and a pair of threaded holes are arranged at the lower end which are flush with the axial position of the rotor to be tested. The tightening screw 18 is screwed and passed through the threaded hole to clamp the measured helical rotor, so that the electric rotating table 17 drives the measured rotor 2 to rotate to realize precise indexing.
 see Figure 5 with Image 6 The electric rotary table 17 fixedly arranged on the front...
