Technical Field

[0001] The utility model relates to the technical field of compressor assembly tooling, and particularly relates to a tooling for assembling a stator. Background Technique

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of a refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it through the rotation of the motor driving the scroll disk, and then discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle.

[0003] During the assembly process of an electric scroll compressor, since the rotor component is installed first and there is a permanent magnet inside the rotor component, when installing the stator, it will attract the stator, resulting in the skew of the stator assembly position. This tooling reduces the skew situation of the stator during the assembly process. Content of the Utility Model

[0004] To solve the problems in the background technique, the utility model proposes a tooling for assembling a stator, and the utility model reduces the skew situation of the stator during the assembly process.

The positioning plate is provided with positioning pin holes, and positioning pins are installed in the positioning pin holes to connect the positioning plate with the housing. A plurality of the stator fixing structures are circumferentially and spacedly arranged on the positioning plate, and the plurality of stator fixing structures are used for clamping and positioning the edge of the stator body. A plurality of positioning jacks are circumferentially and spacedly opened on the stator body. A plurality of the guiding columns are spacedly opened on the guiding plate, and the plurality of guiding columns are respectively inserted and matched with a part of the positioning jacks. Connecting screws are successively and respectively replaced in the other part of the positioning jacks and the positioning jacks where the plurality of guiding columns are located.

[0006] Further, the plurality of stator fixing structures each include a positioning column and a fixing screw. A plurality of shaped holes are circumferentially opened on the edge of the stator body. One side of the positioning column is attached to the edge of the corresponding positioning plate, and the side of the positioning column away from the positioning plate is clamped and matched with the corresponding shaped hole of the stator body. The fixing screw penetrates through the positioning column and is threadedly connected with the positioning plate.

[0007] Further, the number of the positioning pin holes is at least two. At least two positioning pin holes are circumferentially and spacedly arranged on the positioning plate. At least two positioning pins are respectively inserted and matched in at least two positioning pin holes, and at least two positioning pins are used for connecting with the housing.

[0008] Furthermore, the number of the guiding columns is three, and the number of the positioning jacks is six. Three of the guiding columns are in one-to-one plug-in fit with three of the positioning jacks.

[0009] Advantages of the present utility model: The positioning plate of the present utility model is connected to the positioning pin hole and the housing through the positioning pin shaft to fix the positioning plate on the housing. The stator fixing structure realizes the clamping of the stator body to ensure the proper installation of the stator body. In addition, through the guiding plate and multiple guiding columns, the stator body is further positioned under the action of the multiple guiding columns. A part of the positioning jacks on the stator body are connected with screws by threads to achieve the complete fixation of the stator body.
