[0025] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0026] Reference Figures 1 to 2 As shown, the bidirectional compressor piston rapid entry fixture includes:

[0027] The base 10 has an open mounting cavity 101 at the upper end, and the side wall of the base 10 is provided with an opening 102 communicating with the mounting cavity 101.

[0028] A dividing disc 11 is rotatably mounted within a mounting cavity 101. At least two dividing cavities 111 are spaced apart on the sidewall of the dividing disc 11, penetrating the upper and lower end faces of the disc. Each dividing cavity 111 has an inlet 117 on its sidewall. A positioning hole 113 is located at the center of the upper end face of the dividing disc 11 for mounting a swashplate shaft 100. The inner diameter of each dividing cavity 111 is larger than the outer diameter of the lower part of the piston.

[0029] When installing the piston, first insert the shaft portion of the swashplate shaft 100 into the positioning hole 113, ensuring that the swashplate portion of the swashplate shaft 100 contacts the upper end face of the indexing disk 11. When rotating the indexing disk 11, the inlet 117 and opening 102 of one of the indexing chambers 111 align. Push the piston into the indexing chamber 111 through the opening 102, causing the upper part of the piston 200 to hang on the swashplate portion. Figure 3 and Figure 4 As shown, continue rotating the indexing disc 11 to install the next piston 200 until all pistons 200 are installed. Align the piston 200 hole and center hole of the first cylinder with the piston 200 and swashplate shaft 100, and then fit the second cylinder onto the piston 200 and swashplate shaft 100. Remove the partially installed first cylinder, piston 200, and swashplate shaft 100 from the indexing disc 11, and rotate the first cylinder 180 degrees. Fit the second cylinder onto the first cylinder, ensuring that the positions of the piston 200 and swashplate shaft 100 correspond to the piston 200 hole and shaft hole on the first cylinder. This reduces the time required for piston 200 alignment, facilitates installation, and makes operation convenient.

[0030] In a specific embodiment of this utility model, a bearing mounting hole is provided in the base 10. The bearing mounting hole is located below the mounting cavity 101 and communicates with the mounting cavity 101. A first bearing 14 is provided in the bearing mounting hole. A mounting shaft 116 that can be inserted into the first bearing 14 is provided on the lower end face of the indexing disc 11. The indexing disc 11 rotates relative to the base 10 through the mounting shaft 116 and the first bearing 14. The rotation structure of the indexing disc 11 is simple and convenient for maintenance and replacement.

[0031] In a specific embodiment of this utility model, a first space 103 is provided between the lower end face of the indexing disk 11 and the inner bottom surface of the mounting cavity 101. The reserved first space 103 facilitates the rotation of the indexing disk 11 and provides sufficient space for the lower part of the piston 200 to be placed, so that the piston will not contact or collide with the inner bottom surface of the mounting cavity 101 when the indexing disk 11 rotates.

[0032] In a specific embodiment of this utility model, the positioning hole 113 includes a first hole 114 and a second hole 115 located below the first hole 114. The inner diameter of the first hole 114 is larger than the inner diameter of the second hole 115, and the inner diameter of the second hole 115 is larger than or equal to the outer diameter of the swashplate shaft 100. Specifically, the inner diameter of the second hole 115 being larger than or equal to the outer diameter of the swashplate shaft 100 means that the inner diameter of the second hole 115 is slightly larger than or equal to the outer diameter of the shaft portion of the swashplate shaft 100, facilitating the insertion of the shaft portion of the swashplate shaft 100 into the second hole 115, thereby achieving the positioning and installation of the swashplate shaft 100.

[0033] In a specific embodiment of this utility model, a boss 112 is provided in the middle of the indexing disk 11. The upper end surface of the boss 112 is lower than the upper end surface of the base 10. The upper end surface of the boss 112 is used to contact the shaft portion in the swashplate shaft 100, and the upper end surface of the indexing disk 11 is used to contact the swashplate in the swashplate shaft 100, so as to support the swashplate shaft 100 through the upper end surface of the boss 112 and the upper end surface of the indexing disk 11. A positioning hole 113 is provided in the middle of the boss 112, such as... Figure 2 As shown.

[0034] In a specific embodiment of this utility model, a base plate 12 is provided below the base 10, and at least two support columns 13 are provided between the base plate 12 and the base 10. The base plate 12 and the support columns 13 can appropriately increase the height of the base 10, so as to facilitate the operator to rotate the indexing disc 11 and install the piston 200.

[0035] In a specific embodiment of this utility model, the upper end of the support column 13 is provided with a threaded part, the lower part of the support column 13 is provided with a first threaded hole, the lower end face of the base 10 is provided with a second threaded hole, the threaded part is screwed into the second threaded hole, the base plate 12 is provided with a third threaded hole, and the lower end of the support column 13 is connected to the base plate 12 by a screw passing through the third threaded hole and the second threaded hole.

[0036] In a specific embodiment of this utility model, the number of indexing chambers 111 is 3 or 5, to be applicable to 3-cylinder compressors and 5-cylinder compressors.
