The utility model installs the rotor 7 at the desired position, the ball probe 307 contacts the surface of the rotor 7, the rotor 7 rotates, and the rebound force of the spring 302 causes the connecting rod 303 to drive the ball probe 307 to always press against the surface of the rotor 7. The current machine tool angle coordinates are recorded by the sensing device 304, and the fourth axis value A in the processing coordinate system is calculated based on the currently recorded machine tool coordinates, thereby facilitating automatic alignment of the compressor rotor.

[0028] Specifically, the clamping assembly 5 includes a motor 501. A clamping seat 502 is fixedly provided at the output end of the motor 501. A screw rod 503 is threadedly connected to the top of the clamping seat 502. A pressing plate 504 is fixedly provided at the bottom of the screw rod 503. The motor 501 is electrically connected to an external power supply. By the staff placing the rotating shaft 6 inside the clamping seat 502 and turning the screw rod 503 to drive the pressing plate 504 to press down, the position of the rotor 7 is fixed. Then, the motor 501 is turned on to drive the clamping seat 502 to rotate, thereby driving the rotor 7, which is convenient for the compressor rotor to cooperate with the detection assembly 3 to align the profile surface.

[0029] Furthermore, the size and position of the necking 306 match the size and position of the ball probe 307.

[0035] The model of the motor 501 can be: Y90S-2.

[0036] Working principle: When the automatic alignment of the compressor rotor profile by this device is required, the staff places the rotating shaft 6 inside the clamping seat 502, turns the screw rod 503 to drive the pressing plate 504 to press down, thereby fixing the position of the rotor 7. Then, the motor 501 is turned on to drive the clamping seat 502 to rotate, which drives the rotor 7, facilitating the alignment of the compressor rotor with the detection component 3 for the profile. The ball probe 307 contacts the surface of the rotor 7. As the rotor 7 rotates, the resilience of the spring 302 causes the connecting rod 303 to drive the ball probe 307 to always press against the surface of the rotor 7. The current machine tool angle coordinates are recorded by the induction device 304. The fourth axis value A in the machining coordinate system is calculated based on the currently recorded machine tool coordinates, thus facilitating the automatic alignment of the compressor rotor profile. The detection trajectory route of the probe ball is generated by software, and the coordinate of the detection trajectory point is generated through post-processing of the detection trajectory. A suitable detection trajectory point is selected, generally the midpoint of the profile, and the coordinate is (x, y, z, a). Let the machining coordinate system be (X, Y, Z, A), and A0 be the machine tool mechanical coordinate when the probe contacts the workpiece. The machining coordinate system (X, Y, Z) is set by the midpoint method. Figure 4 , move the probe to the point (x, y, z), press Figure 5 Rotate the rotor to make the probe contact the workpiece, record the current fourth axis coordinate A0, and the machining coordinate system A = A0 - a. Input the A value into the fourth axis of the machining coordinate system to complete the alignment of the part.
