specific Embodiment approach 1
[0024] Two V-shaped blocks 2 are placed on the detection frame 1, the workpiece 5 to be tested is placed on the V-shaped block 2, the PSD sensor 6 is fixed on the probe 7, and the probe 7 is placed in the deep hole. The rigid measuring rod 9 and The measuring head 7 is connected, the laser emitter 4 is fixed on the laser adjustment frame 3 and placed outside the deep hole of the workpiece 5 to be measured, and the antenna is drawn from the PSD sensor 6 in the deep hole to the outside of the deep hole of the workpiece 5 to be measured.
[0025] One end of the universal joint 8 is connected to the measuring head 7, and the other end is connected to the measuring rod 9. The measuring rod 9 is connected by multiple short rods of the same length.
