[0003] In the prior art, as disclosed in a guiding and positioning device for automotive electric compressor assembly in a Chinese patent with the patent publication number CN221390926U, which relates to the technical field of automotive electric compressor assembly and positioning. To solve the problems that the positioning device on the existing automotive electric compressor assembly device is relatively simple, thus it is prone to instability during compressor positioning, and it does not have an adjusting function, affecting its operation convenience. Support legs are installed at the four peripheries of the lower surface of the operating table, a bottom plate is installed between the four support legs, and universal wheels are installed at the bottoms of the support legs; it further includes: a positioning mechanism, which is arranged on both sides of the upper surface of the operating table, a first positioning frame and a second positioning frame are arranged on the positioning mechanism, guiding frames are arranged at the front and rear ends of the first positioning frame and the second positioning frame, and a connecting groove is arranged at the temporal part of the guiding frame; a supporting table, which is arranged between the first positioning frame and the second positioning frame, and a motor box is arranged at the bottom of the supporting table.

[0004] In the actual production process, this guiding and positioning device for automotive electric compressor assembly only relies on the positioning mechanism, the first positioning frame, and the second positioning frame to solve the problem of instability during compressor positioning. This guiding and positioning device for automotive electric compressor assembly does not set an automatic alignment device during compressor assembly, resulting in the need to manually align the machine cover and the housing every time during compressor assembly, which affects the efficiency of compressor assembly. Therefore, it needs to be improved. Summary of the Utility Model

After assembling the compressor, the compressor is placed in the water tank, and by observing whether bubbles are generated, the airtightness of the assembled compressor is detected. The scale value set on the upper surface of the scale provides a reference for the distance that the hydraulic tank moves along the Y-axis direction after being forced. The five-centimeter sponge layer plays a buffering role to prevent damage to the outer surface of the compressor shell when the top plate presses against it. The butter in the butter box is applied to the sliding groove with a brush, so that after the machine cover contacts the compressor shell, it fits tightly with the compressor shell and drives the compressor shell to move more smoothly along the X-axis direction to the top plate. The parts box facilitates the placement of the screws, and the screws are installed into the assembly holes and threaded holes with an electric screwdriver, facilitating the assembly of the compressor.

Through the above operations, the effect of good automatic alignment during compressor assembly is achieved. Two slide bars 15 are fixedly connected to the upper surface of the machine table 1. The hydraulic tank 5 is slidably connected to the slide bars 15. The sliding connection of the hydraulic tank 5 in the two slide bars 15 enables the hydraulic tank 5 after force movement not to deviate horizontally when moving along the Y-axis direction, reducing the error that occurs when the alignment rod 9 moves. A water tank 25 is fixedly connected to the outside of the machine table 1. Water is arranged inside the water tank 25.

After assembling the compressor, the compressor is placed in the water tank 25, and by observing whether bubbles are generated, the airtightness of the assembled compressor is detected. The scale value 17 set on the upper surface of the scale 16 provides a reference for the distance that the hydraulic tank 5 moves along the Y-axis direction after being stressed. The five-centimeter sponge layer 18 plays a buffering role to prevent the outer surface of the compressor housing 10 from being damaged when the top plate 3 presses against the compressor housing 10. The butter in the butter box 19 is applied to the chute 2 with a brush 20, so that after the machine cover 12 contacts the compressor housing 10, it fits together with the compressor housing 10 and drives the compressor housing 10 to move along the X-axis direction to the top plate 3 more smoothly. The parts box 21 facilitates the placement of the screws 22, and the screws 22 are installed into the assembly holes 13 and the threaded holes 11 with an electric screwdriver 24, facilitating the assembly of the compressor.
