Description

Technical Field

[0001] The utility model relates to the technical field of automobile air-conditioning compressor processing, in particular to an automobile air-conditioning compressor rear cylinder processing tool. Background Art

[0002] The automobile air conditioning compressor is the heart of the automobile air conditioning refrigeration system, playing the role of compressing and transporting refrigerant vapor. Compressors are divided into two types: fixed displacement compressors and variable displacement compressors. According to different working principles, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors.

[0003] The patent with publication number CN212145499U discloses a tooling for processing the rear cylinder of an automobile air-conditioning compressor, which includes a base plate, a fixed round pin, three support columns and two positioning round pins; the fixed round pin is connected to the middle part of the upper end surface of the base plate and cooperates with the bearing hole of the rear cylinder, and the three support columns are arranged in a triangular shape on the outer side of the fixed round pin and connected to the upper end surface of the base plate. The sides of the support columns are respectively provided with clamping cylinders for pressing and positioning the rear cylinder on the support columns. The device cooperates with the bearing hole through the fixed round pin and is positioned by the positioning round pin, and is supported on the three support columns and the auxiliary support columns, thereby realizing accurate support and positioning of the rear cylinder, and then the rear cylinder is firmly pressed on the support column and the auxiliary support column by the pressure block of the clamping cylinder, so as to avoid the movement of the rear cylinder during machining and affect the machining accuracy. The invention has the advantages of high automation, fast clamping speed, high machining accuracy and high working stability. However, the device has the following problems: when the cylinder body is positioned by using fixed round pins and locating round pins, the fixed round pins and the locating round pins are both fixed on the top of the base plate. If the cylinder body is to be firmly limited and positioned, there needs to be a large friction between the locating round pins and the fixed round pins and the slot holes and the bearing holes on the cylinder body. However, the rear cylinder body is generally made of metal casting and is heavy. In addition, there is friction between the fixed round pins and the locating round pins and the cylinder body. This results in that after the cylinder body processing is completed, it is difficult to manually detach the rear cylinder body from the locating round pins and the fixed round pins and move it out of the base plate, which is not convenient for subsequent other cylinder body processing. For this reason, a rear cylinder body processing tooling for an automobile air-conditioning compressor is proposed to solve the problem that the existing compressor cylinder body is difficult to quickly install and disassemble from the processing tooling.

[0024] Furthermore, the positioning column 5 and the limiting column 6 both penetrate the inner wall of the tooling seat 1 and can move up and down freely. The top of the electric telescopic rod 8 is fixedly connected to the lifting plate 4. After the processing of the rear cylinder of the compressor is completed, the clamping block 3 is loosened, and the electric telescopic rod 8 is turned on so that the lifting plate 4, with the cooperation of the stabilizing mechanism, drives the positioning column 5 and the limiting column 6 to move downward so that they are disengaged from the groove hole in the rear cylinder body to complete the disassembly, thereby improving the convenience of disassembling the rear cylinder body from the tooling and facilitating the subsequent processing of other cylinder bodies.

[0025] Furthermore, the fastening mechanism 7 includes a groove 701 extending through one end of the limiting column 6 , and two groups of fastening blocks 702 are arranged in the inner cavity of the groove 701 . There is a certain friction force between the fastening blocks 702 and the groove 701 .

[0026] Furthermore, one end of the fastening block 702 is fixedly connected with a fastening plate 703, which is located at the outermost end of the inner cavity of the groove 701 and has the same arc shape as the outer circle of the limiting column 6, and the outer end surface of the fastening plate 703 is relatively smooth.

[0027] Furthermore, a guide slope 704 is provided at one adjacent end of the fastening block 702, and a conical block 705 is provided between the two fastening blocks 702. The guide slope 704 fits with the inclined surface on the conical block 705, and an adjusting screw 706 is threadedly connected to the inner wall of the conical block 705. The adjusting screw 706 passes through the limiting column 6, and the adjusting screw 706 and the limiting column 6 are limited by a bearing 707. An adjusting knob 708 is fixedly connected to the top of the adjusting screw 706.
