The compressor pump body is located below the stator 91, and the rotor 92 is located at the center of the stator 91.

[0062] The working principle of the utility model is:

[0063] When the utility model starts working, the compressor semi-finished product conveyor line 11 conveys multiple compressor pump bodies 90 one by one to the bottom of the pump body oiling device 2. At this time, the compressor semi-finished product conveyor line 11 positions and lifts the pump body conveying tooling 12, the compressor semi-finished product 9 stops moving forward, and the positioning cylinders 82 of the two compressor pump body positioning devices 8 drive the positioning claws 83 to slide forward. The positioning claws 83 of the two positioning cylinders 82 position the compressor casing left and right, and the pump body oiling device 2 starts to start. The oil injection lifting cylinder 22 drives the oil injection switch cylinder 23 to descend so that the oil outlet 28 of the oil injection switch valve 26 is aligned with the rotating shaft 93 of the compressor pump body 90, and then the oil injection switch cylinder 23 drives the oil injection switch valve 26 to open, and the oil outlet 28 flows out lubricating oil, and the lubricating oil flows to the bearings in the compressor pump body 90 to lubricate the bearings. After the oil is filled, the oil filling switch cylinder 23 drives the oil filling switch valve 26 to close, the oil filling lifting cylinder 22 drives the oil filling switch cylinder 23 to rise, and the oil receiving translation cylinder 24 drives the oil receiving groove 25 to slide directly below the oil outlet 28 of the oil filling switch valve 26, and the oil receiving groove 25 receives the excess lubricating oil flowing out of the oil outlet 28. After that, all parts of the pump body oil filling device 2 return to their original positions to prepare for the next inspection.

[0064] The compressor semi-finished product conveyor line 11 continues to convey the oil-filled compressor semi-finished product 9 forward to the bottom of the pump body rotation vacuum detection device 3. At this time, the compressor semi-finished product conveyor line 11 positions and lifts the pump body conveying tooling 12, the pump body rotation vacuum detection device 3 is started, and the pump body rotation lifting motor 32 drives the first pump body clamping assembly 38, the first clamping lifting seat 35 and the pump body rotation lifting seat 34 to slide downward together, and the pump body rotation drive shaft 37 moves downward, and the first center positioning shaft 311 of the pump body rotation drive shaft 37 is inserted into the shaft hole 930 of the rotating shaft 93 of the compressor pump body 90, and the first driving protrusion 312 is in transmission cooperation with the groove 931 at the upper end of the rotating shaft 93; after the first pump body clamping assembly 38 is lowered into place, the first pump body clamping assembly 38 is started, and the clamping cylinder 36 drives the left clamping jaw 310 and the right clamping jaw 39 to close, and the left clamping jaw 310 and the right clamping jaw 39 clamp the compressor casing.

[0065] The pump body vacuum detection mechanism 5 is started, and the detection lifting motor 52 drives the detection lifting seat 53 to slide downward so that the detection joint 59 is aligned with the copper tube 94 on the side of the compressor casing 95. Then the correction jaw cylinder 55 drives the left correction jaw 57 and the right correction jaw 56 to close. The left correction jaw 57 and the right correction jaw 56 drive the copper tube on the side of the compressor casing to be aligned with the detection joint 59. Then the detection telescopic cylinder 58 drives the detection joint 59 to move forward, and the detection joint 59 is connected with the copper tube 94 on the compressor casing 95.

[0066] Afterwards, the pump body rotating motor 33 drives the pump body rotating drive shaft 37 to rotate, and the pump body rotating drive shaft 37 drives the rotating shaft 93 of the compressor pump body 90 to rotate. When the rotating shaft 93 of the compressor pump body 90 rotates, a vacuum will appear in the qualified compressor pump body 90, and the negative pressure gauge will show a pressure change. An unqualified compressor pump body 90 will not have a vacuum, and the negative pressure gauge will not have a pressure change. Unqualified compressor semi-finished products 9 will be transported away, and qualified compressor semi-finished products 9 will be transported downward to the rotor height inspection device 4 by the compressor semi-finished product conveying line 11. All components of the pump body rotating mechanism 30 and the pump body vacuum detection mechanism 5 return to their original positions to prepare for the next inspection.

[0067] When the compressor semi-finished product conveyor line 11 conveys the compressor semi-finished product 9 to the bottom of the rotor height inspection device 4, the compressor semi-finished product conveyor line 11 positions and lifts the pump body conveying tooling 12, and then the rotor height inspection device 4 is started, and the inspection lifting motor 42 drives the inspection lifting main seat 43 and the second pump body clamping assembly 46 to slide downward. After the second pump body clamping assembly 46 descends into place, the second pump body clamping assembly 46 is started, and the clamping cylinder 36 drives the left clamping jaw 310 and the right clamping jaw 39 to close, and the left clamping jaw 310 and the right clamping jaw 39 clamp the compressor casing.

[0068] Then, the inspection lifting cylinder 44 drives the inspection lifting sub-seat 45 to slide downward, and the rotor height detection rod 49 and the stator positioning piece 48 move downward. The lower end of the rotor height detection rod 49 first touches the upper end of the shaft 93 (the horizontal height of the shaft is consistent with the horizontal height of the rotor), and then the lower end of the stator positioning piece 48 touches the stator 91. The rotor 92 and the stator 91 of the qualified semi-finished compressor 9 have a specified height difference. The horizontal height of the shaft 93 is higher than the horizontal height of the stator. Due to the height difference, when the stator positioning piece 48 touches the stator 91, the lower end of the rotor height detection rod 49 moves upward. At this time, the detection sensor 410 will detect the displacement of the rotor height detection rod 49, and then send a signal to the controller. The controller determines whether the displacement height of the rotor height detection rod exceeds the specified height difference. If the displacement height of the height detection rod exceeds the specified height difference, the semi-finished compressor 9 is judged to be unqualified, otherwise, it is qualified. After that, all components of the rotor height inspection device 4 return to their original positions to prepare for the next inspection.

[0069] When the compressor semi-finished product conveyor line 11 conveys the compressor semi-finished product 9 with the height inspection forward to the bottom of the pump body shaft torque testing device 7, the compressor semi-finished product conveyor line 11 positions and lifts the pump body conveying tooling 12, and then the pump body shaft torque testing device 7 is started, the inspection lifting motor 72 drives the inspection lifting seat 73 and the second clamping lifting seat 77 to slide downward synchronously, the inspection rotating shaft 75 moves downward, and the second center positioning shaft of the inspection rotating shaft 75 is inserted into the shaft hole 930 of the rotating shaft 93 of the compressor pump body 90, the second driving protrusion is matched with the groove 931 at the upper end of the rotating shaft 93, and the third pump body clamping assembly 78 slides downward. After the third pump body clamping assembly 78 drops into place, the third pump body clamping assembly 78 is started, and the clamping cylinder 36 drives the left clamping jaw 310 and the right clamping jaw 39 to close, and the left clamping jaw 310 and the right clamping jaw 39 clamp the compressor casing 95. Then, the inspection rotating motor 74 drives the inspection rotating shaft 75 to rotate, and the pump body rotating drive shaft 37 drives the rotating shaft 93 of the compressor pump body 90 to rotate through the coupling 712, the torque sensor 710, the friction torque limiter 711, and the inspection rotating shaft 75 in turn. The friction torque limiter 711 has a set transmission torque. When the rotational resistance of the rotating shaft 93 of the compressor pump body 90 exceeds the set transmission torque, the friction torque limiter 711 will disconnect the power to protect the torque sensor 710, and the controller determines that the compressor pump body 90 is unqualified. On the contrary, if the rotational resistance of the rotating shaft 93 of the compressor pump body 90 does not exceed the set transmission torque, the inspection rotating shaft 75 can drive the rotating shaft 93 of the compressor pump body 90 to rotate, and the rotating shaft torque test of the compressor pump body 90 is qualified. Afterwards, all components of the pump body shaft torque testing device return to their original positions to prepare for the next test, and the compressor semi-finished product conveyor line transports the qualified compressor semi-finished products away.
