[0002] With the rapid development of compressors, the demand for motors has only increased. In addition to the squirrel-cage induction motors applicable to most general compressor types, there are also slip-ring induction motors applicable to compressors with higher starting torque requirements and variable-frequency speed-regulating motors applicable to compressors that require variable-frequency speed regulation.

[0003] For these compressors, as a key device that converts electrical energy into mechanical energy, the stability and efficiency of the motor are crucial. And as the fixed part of the motor, the dimensional accuracy of the outer diameter of the motor stator directly affects the overall performance and reliability of the motor.

[0004] Therefore, precise detection of the outer diameter of the motor stator is an important link in the motor production process. At present, the outer diameter detection of the motor stator mainly relies on traditional mechanical measurement methods. Workers need to place the stator on the detection platform, make the stator flush with the center drill in the axial direction, then control the center drill to fix the stator in the axial direction, and then drive the stator to rotate to detect the runout of the stator. Although these methods can meet the detection requirements to a certain extent, the detection efficiency is low and the measurement speed is slow.

[0005] Regarding the above related technologies, the inventor believes that a stator precision detection platform with higher detection efficiency is needed. Summary of the Invention

[0026] The following will Figure 1 - attached Figure 4 make a further detailed description of this application.

[0027] The embodiment of this application discloses a precision detection table for a compressor motor stator.

[0028] Refer to Figure 1 and Figure 2, A precision detection platform for a compressor motor stator, including a tabletop 1, a sliding clamping seat 3, a lifting support platform 4, a fixed clamping seat 2, and a radial runout detection platform 6 arranged on the tabletop 1; the fixed clamping seat 2 is fixedly arranged on the tabletop 1 and the fixed clamping seat 2 is provided with a motor, and a thimble is fixed on the output shaft of the motor, and the thimble faces the lifting support platform 4. The lifting support platform 4 is arranged between the sliding clamping seat 3 and the fixed clamping seat 2 for placing the stator. The sliding clamping seat 3 can move away from or close to the lifting support platform 4. One side of the sliding clamping seat 3 facing the lifting support platform 4 is also provided with a thimble. After the thimble of the fixed clamping seat 2 and the thimble of the sliding clamping seat 3 clamp the stator and make the stator rotate, the radial runout of the stator can be detected by the radial runout detection platform 6.

[0029] A track is provided at the bottom of the sliding clamping seat 3, and a cylinder capable of driving the sliding clamping seat 3 to move on the track is arranged on the tabletop 1.

[0030] Refer to Figure 1 and Figure 2 , A transmission component 5 is arranged between the sliding clamping seat 3 and the lifting support platform 4; the input end of the transmission component 5 is in transmission connection with the lifting support platform 4, and the output end of the transmission component 5 is connected to the lifting support platform 4; after the sliding clamping seat 3 moves away from the lifting support platform 4, the lifting support platform 4 is in the highest position, which is convenient for the staff to place the stator on the lifting support platform 4. When the sliding clamping seat 3 moves towards the lifting support platform 4, the transmission component 5 will drive the lifting support platform 4 to move downward, so that the central axis of the stator can be approximately collinear with the central axes of the thimbles on the sliding clamping seat 3 and the fixed clamping seat 2. Thereby, the error of the radial runout generated when the stator rotates can be reduced.

[0031] Refer to Figure 1 and Figure 2 , The lifting support platform 4 includes guide columns 41, a lifting platform 42, and an arc support platform 43; there are multiple guide columns 41. In this embodiment, the number of guide columns 41 is 4. The bottom of the guide columns 41 is fixedly arranged on the tabletop 1, and the lifting platform 42 is slidably arranged on the guide columns 41. Under the action of the transmission component 5, the lifting platform 42 can slide along the length direction of the guide columns 41 to realize lifting. A retaining cap 411 is fixed at the top of the guide columns 41 to prevent the lifting platform 42 from detaching from the guide columns 41.

[0032] The arc support platform 43 is detachably arranged on the lifting platform 42, and the two are connected by plugging and unplugging. The arc support platform 43 is used to support the stator. When the staff needs to detect the stator, they only need to place the stator on the arc support platform 43 and then start the sliding clamping seat 3.

[0033] The arc support platform 43 has multiple models with different diameters and can be adapted to stators with different diameters.

[0034] The arc-shaped support table 43 is provided with a plurality of picking and placing grooves 431. Through the picking and placing grooves 431, it is convenient for the staff to place the stator on the arc-shaped support table 43.

[0035] The transmission assembly 5 includes a wire winding wheel 52, an elastic member 53, a rope 54, a first rack 55 and a first gear 56; a first through groove 51 is provided on the tabletop 1, and the first through groove 51 communicates the upper surface and the lower surface of the tabletop 1. The wire winding wheel 52 is rotatably arranged on the groove wall of the first through groove 51. The elastic member 53 is a spring. The upper part of the elastic member 53 is fixedly connected to the lower surface of the lifting table 42, and the lower surface of the elastic member 53 is fixedly connected to the upper surface of the tabletop 1. One end of the rope 54 is fixedly arranged on the lower surface of the lifting table 42, and the other end passes through the lower surface of the tabletop 1 from the upper surface of the tabletop 1 and is fixedly connected to the wire winding wheel 52.

[0036] The wire winding wheel 52 can wind the rope 54. After the rope 54 is wound, the rope 54 can pull the lifting table 42 to move downward. The first rack 55 is fixedly connected to the sliding clamping seat 3, the first gear 56 is fixedly connected to the wire winding wheel 52, and the first rack 55 matches the first gear 56. When the sliding clamping seat 3 moves towards the lifting support table 4, the first rack 55 meshes with the first gear 56 and drives the wire winding wheel 52 to rotate, so that the lifting table 42 can be lowered, so that the axis of the stator can be substantially flush with the axis of the thimble. At this time, the thimbles on the sliding clamping seat 3 and the fixed clamping seat 2 also just abut against both ends of the stator, clamp both ends of the stator, and drive the stator to rotate.

[0037] Refer to Figure 3 , the radial runout detection table 6 includes a longitudinal displacement seat 61, a transverse displacement seat 62 and a runout measuring instrument 63; the longitudinal displacement seat 61 is fixedly arranged on the tabletop 1 and can drive the transverse displacement seat 62 to move away from or close to the lifting support table 4. The longitudinal displacement seat 61 is provided with a driving rod 64, and a motor connected to the driving rod 64 is built in the longitudinal displacement seat 61. The driving rod 64 is a lead screw, and the driving rod 64 and the transverse displacement seat 62 are in a lead screw transmission.

[0038] An adjusting rod 65 is rotatably arranged on the transverse displacement seat 62, the runout measuring instrument 63 is arranged on the adjusting rod 65, and the runout measuring instrument 63 is in a lead screw transmission connection with the adjusting rod 65. The detection end of the runout measuring instrument 63 faces the lifting support table 4. By rotating the adjusting rod 65, the runout measuring instrument 63 can move relative to the axis direction of the stator. In this embodiment, there are 2 runout measuring instruments 63, and in other embodiments, there may also be 1 or more than 2.

[0039] The implementation principle of the embodiment is as follows: Place the stator on the arc-shaped support table 43, then slide the clamping seat 3 towards the stator. The first rack 55 on the sliding clamping seat 3 will drive the first gear 56 to rotate, causing the wire winding wheel 52 to rotate. After the rope 54 is wound, the rope 54 can pull the lifting platform 42 downward, so that the stator moves downward. After the axis of the stator is approximately collinear with the axis of the thimble, the thimble can just clamp the stator, and then drive the stator to rotate. Then, the runout of the stator is detected by the runout measuring instrument 63.

The second rack 58 is fixed to the sliding clamping seat 3, and the second rack 58 passes downward through the second through groove 57. The lower end of the guide post 41 passes through the table top 1 and is located on the lower surface of the table top 1. The second gear 59 is fixedly arranged at the lower end of the guide post 41, and the second gear 59 is adapted to the second rack 58.

[0043] There are multiple guide posts 41, and the multiple guide posts 41 are evenly distributed on both sides of the second rack 58. In this embodiment, there are 4 guide posts 41, two on one side of the second rack 58 and two on the other side of the second rack 58. During the process of the sliding clamping seat 3 sliding towards the stator, the second rack 58 can engage with the second gears 59 on the four guide posts 41 and drive the guide posts 41 to rotate. The threaded sections of the guide posts 41 on one side of the second rack 58 are arranged in the opposite direction to the threaded sections of the guide posts 41 on the other side. When the four guide posts 41 rotate, the lifting platform 42 can rise or fall in the horizontal direction.
