The compressor is the core component of the automobile air-conditioning system and the main component that determines the cooling effect of the air-conditioning system. Therefore, the compressor usually needs to have high reliability.

[0003] The existing technology controls the piston sliding shoe clearance by the size of related parts, and then controls it by re-measuring the piston sliding shoe clearance through equipment. However, the accuracy of the piston sliding shoe clearance cannot be well controlled. The piston sliding shoe clearance will affect the noise and reliability of the compressor. Therefore, it is necessary to improve the accuracy of the piston sliding shoe clearance, and thus a means to accurately measure the accuracy of the piston sliding shoe clearance is needed.

[0004] In view of this, a shoe clearance detection tool for an automotive air-conditioning compressor is disclosed in the patent document with application number 202122561405.0. When the tool in the above-mentioned prior art rotates the main shaft during the detection process, it is easy to cause the main shaft to shake, making it difficult to ensure the accuracy of the detection results.

[0009] Furthermore, the number of the brackets is two, and the two brackets are arranged at an interval.

[0010] Compared with the prior art, the utility model has the following advantages: the automobile air-conditioning compressor sliding shoe clearance detection device can tighten the limit block through the set spring when working, and the spring can make the pressure plate always be in a state of pressing on the main shaft. At the same time, the positioning rod can be rotated so that the positioning block can move the limit block in the limit cavity, and the limit block can be clamped by the positioning block, so that the pressure plate fixes the main shaft to avoid shaking when the main shaft rotates, thereby ensuring the accuracy of the detection result.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0016] Example

[0017] See also Figures 1 to 3As shown, it should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, if there are references to terms such as "upper", "lower", "left", "right", "middle" and "one" in this specification, they are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship, without substantially changing the technical content, should also be regarded as the scope of the implementation of the utility model.

[0018] The automobile air-conditioning compressor sliding shoe clearance detection device in this embodiment includes a base 1, a bracket 2, a pressure plate 3 and a micrometer 4. The bracket 2 and the micrometer 4 are both arranged on the base 1. The pressure plate 3 is arranged on the bracket 2 through a clamping structure. There are two brackets 2, and the two brackets 2 are arranged at intervals. The bracket 2 is provided with a U-shaped groove 15 for placing the main shaft and a V-shaped groove 16 for placing the sliding shoe.

[0019] The clamping structure in this embodiment includes a guide rod 5, a limit block 6, a spring 7, a limit cavity 8, a positioning cavity 9, a positioning block 10, a positioning rod 11, a limit ring 12, a limit groove 13 and a handle 14. The limit cavity 8 is arranged on the bracket 2, one end of the guide rod 5 is fixed to the pressure plate 3, the limit block 6 is fixed to the other end of the guide rod 5, the limit block 6 is located in the limit cavity 8, the spring 7 is mounted outside the guide rod 5, and the two ends of the spring 7 are respectively abutted against the limit block 6 and the limit cavity 8.

[0020] The positioning cavity 9 in this embodiment is arranged on the side wall of the limiting cavity 8, the positioning block 10 is located in the positioning cavity 9, one end of the positioning rod 11 is fixed to the limiting ring 12, the other end of the positioning rod 11 is fixed to the handle 14, the limiting groove 13 is arranged on the positioning block 10, and the limiting ring 12 is located in the limiting groove 13.

[0021] Specifically, when the automobile air-conditioning compressor sliding shoe clearance detection device is working, the limit block 6 can be pressed tightly by the set spring 7, so that the pressure plate 3 can press the main shaft.
