Description

Technical Field

[0001] This utility model relates to the field of compressor swashplate technology, and more particularly to the outer ring of the swashplate of an automotive air conditioning compressor. Background Technology

[0002] The swash plate outer ring is a key component of a variable displacement compressor in automobiles. The rotation of the main shaft drives the swash plate outer ring to rotate, which in turn transmits this rotation to the sliding shoes, pushing the piston in axial reciprocating motion. The main function of the swash plate outer ring, along with the compressor piston, is to handle the intake and compression of the refrigerant within the compressor, thus achieving the transformation of the refrigerant. The intake refrigerant is compressed by the compressor into a high-temperature, high-pressure medium before being expelled, thereby enabling the variable displacement and cooling / heating functions of the automotive air conditioning system.

[0003] However, the existing swashplate outer rings of automotive air conditioning compressors generally suffer from a fixed structural design, making it difficult to meet the needs of diverse usage scenarios. On the one hand, traditional swashplate outer rings are mostly integrally formed or fixedly connected to the swashplate body, and the tilt angle cannot be adjusted, resulting in a fixed compressor displacement that cannot be adapted to different types of compressors. On the other hand, the existing swashplate outer rings are integral fixed-diameter structures, which can only match a single model of compressor, lacking versatility. Moreover, after long-term use, when the outer ring wears down and the diameter decreases and the fitting clearance increases, the entire outer ring or even the swashplate assembly needs to be replaced, resulting in high maintenance costs and serious waste of resources. Therefore, in response to the above situation, there is an urgent need to develop an automotive air conditioning compressor swashplate outer ring that can precisely adjust the tilt angle of the swashplate outer ring in 5° intervals through the cooperation of an arc-shaped guide rail and a second countersunk bolt. At the same time, the maximum outer diameter can be flexibly controlled by increasing or decreasing the number of detachable semi-circular rings fixed by the first countersunk bolt. This dual adjustment design can adapt to different usage needs, and the overall structure is detachable and easy to assemble, making it highly practical and overcoming the shortcomings in current practical applications to meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide an outer ring of a swashplate for an automotive air conditioning compressor to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The swash plate outer ring of an automotive air conditioning compressor includes an inner swash plate, an outer swash plate body, an arc-shaped guide rail, a detachable semi-circular ring, a first countersunk bolt, and a second countersunk bolt. The inner swash plate has arc-shaped guide rails fixed to its two functional sides. The outer swash plate body is mounted on the outer side of the arc-shaped guide rails and slides in contact with them. The inner side of the outer swash plate body has an arc-shaped groove that mates with the arc-shaped guide rails. The outer swash plate body is detachably fixed to the arc-shaped guide rails by multiple second countersunk bolts. The arc-shaped guide rails have two rows of second threaded holes for installing the second countersunk bolts, with an included angle of 5° between two adjacent second threaded holes. Multiple detachable semi-circular rings are detachably mounted on the outer side of the outer swash plate body, and these detachable semi-circular rings are fixed to the outer swash plate body by multiple first countersunk bolts.

[0006] Preferably, the inner ring of the swash plate, the outer ring of the swash plate, the arc-shaped guide rail, and the detachable semi-circular ring are all made of alloy steel.

[0007] Preferably, the outer ring of the swashplate is provided with a plurality of first threaded holes for installing the first countersunk bolts.

[0008] Preferably, the detachable semi-circular ring is provided with multiple countersunk holes for the first countersunk bolt to pass through.

[0009] The beneficial effects of this utility model are as follows: When assembling the swashplate outer ring of the automotive air conditioning compressor, the second countersunk bolt is first removed, and then the swashplate outer ring body is rotated up and down along the arc surface of the arc guide rail to adjust the tilt angle of the swashplate outer ring body. After adjustment, the second countersunk bolt is screwed into the second threaded hole to fix the swashplate outer ring body. Since the included angle between two adjacent second threaded holes is 5°, the adjustment angle can be accurately controlled. Different tilt angles of the swashplate outer ring body can meet different usage requirements. In addition, multiple detachable semi-circular rings are fixed to the outside of the swashplate outer ring body by the first countersunk bolt. The maximum outer diameter can be controlled by adjusting the number of detachable semi-circular rings on the outer ring of the swashplate outer ring body to adapt to different usage requirements. In summary, this utility model, through the cooperation of the arc-shaped guide rail and the second countersunk bolt, can precisely adjust the tilt angle of the outer ring of the swashplate at 5° intervals. At the same time, it can flexibly control the maximum outer diameter by increasing or decreasing the number of detachable semicircular rings fixed by the first countersunk bolt. The dual adjustment design can adapt to different usage needs, and the overall structure is detachable, easy to assemble, and highly practical. Attached Figure Description
