[0026] See also Figures 1 to 4In the embodiment of the utility model, an assembly positioning fixture includes a bottom overlapping top plate 1, both sides of the upper end of the bottom overlapping top plate 1 are fixedly connected with an I-shaped lap plate 2, the upper end of the I-shaped lap plate 2 is fixedly connected with an assembly positioning placement box 3, both sides of the assembly positioning placement box 3 are fixedly connected with a limited adjustment rod 4 through a through groove, the surface of the limited adjustment rod 4 is slidably connected with an L-shaped slidable rod 5, the top of the front of the L-shaped slidable rod 5 is fixedly connected with an auxiliary sliding card slot block 6, and the inner wall of the auxiliary sliding card slot block 6 is slidably connected with a positioning card slot block 6 through a sliding top block 7. The clamping rod 8 and one side of the I-shaped strap 2 are fixedly connected with an adjustment buffer device 9, and the automobile air-conditioning compressor cylinder is slid into the assembly positioning placement box 3. At the same time, the front axle contacts the sponge arc-shaped recessed block 903, and the adjustment slider 902 slides downward in the main support groove block 901. While the compression spring 904 is squeezed, the main shaft of the automobile air-conditioning compressor cylinder is also partially buffered. Therefore, when the automobile air-conditioning compressor cylinder is placed on the assembly positioning fixture for processing and installation, the main shaft can be protected from damage, thereby avoiding difficulties in maintenance.

[0027] See also Figures 2-3 Both sides of the inner wall of one side of the assembly positioning placement box 3 are fixedly connected with fixed straps 10, and both sides of the front side of the fixed straps 10 are rotatably connected with guide pulleys 12 through auxiliary support shafts 11. The guide pulleys 12 guide the placement position when the automobile air-conditioning compressor cylinder is placed into the assembly positioning placement box 3 to avoid jamming during the connection.

[0028] See also Figures 1-2 A rubber pad 13 is fixedly connected to the middle of the inner wall of one side of the assembly positioning and placement box 3, and a lifting card plate 14 is fixedly connected to the bottom of both sides of the assembly positioning and placement box 3. The rubber pad 13 performs friction limiting and fixing on the automobile air-conditioning compressor cylinder, making it convenient for the overall assembly of the automobile air-conditioning compressor cylinder in the later stage. The lifting card plate 14 facilitates the overall lifting of the assembly positioning fixture and places it in the next process to continue to complete the assembly operation.

[0029] See also Figures 1-2 Both sides of the lower end of the bottom overlapping top plate 1 near the middle are fixedly connected with additional fixing rods 15, and one end of the additional fixing rod 15 is fixedly connected with a bottom top foot 16. The additional fixing rod 15 serves as a connection between the bottom top foot 16 and the bottom overlapping top plate 1, so that the overall stability of the bottom of the assembly positioning fixture is enhanced, and the assembly operation can be carried out more stably.

[0030] See also Figure 4The adjustment buffer device 9 includes a main body support slot block 901, and an adjustment slider 902 is slidably connected to one side of the main body support slot block 901. Both ends of the adjustment slider 902 fit the inner wall of the slide slot of the main body support slot block 901, so that the adjustment slider 902 is restricted when sliding in the main body support slot block 901 and is always in a vertical up and down sliding state.

[0031] See also Figure 4 The upper end of the adjusting slider 902 is fixedly connected with a sponge arc-shaped concave block 903, and both sides of the lower end of the adjusting slider 902 are fixedly connected with compression springs 904. The principle of the compression spring 904 is: the compression spring provides resistance to the external load pressure. The compression spring is generally a metal wire with equal pitch coiling and a fixed wire diameter. There is a certain gap between the turns of the compression spring 904. When subjected to an external load, the spring contracts and deforms to store deformation energy.

[0032] The working principle of the utility model is:

[0033] The automobile air-conditioning compressor cylinder is moved downward from the main shaft and slides downward along the guide pulley 12, and is completely placed in the assembly positioning box 3. The rubber pad 13 further limits and reinforces the automobile air-conditioning compressor cylinder. The main shaft touches the sponge arc-shaped concave block 903 and drives the adjustment slider 902 to slide downward in the main support groove block 901, and the compression spring 904 is compressed by the vertical downward force. The compression spring 904 partially buffers the downward force to protect the main shaft from damage.

[0034] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
