DETAILED DESCRIPTION

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figures 1-4 As shown, this utility model provides a swashplate positioning structure for an automotive air conditioning compressor, including a swashplate body 1. The swashplate body 1 has a swashplate seat 4 inside. The inner wall of the swashplate body 1 is symmetrically provided with auxiliary positioning mechanisms 3 for use with the swashplate seat 4. The auxiliary positioning mechanisms 3 can perform secondary positioning of the swashplate seat 4, so that the swashplate body 1 achieves the best positioning effect. The inner wall of the swashplate body 1 and the outer surface of the swashplate seat 4 are provided with positioning components 2 in a circular array, which simplifies the positioning structure of the swashplate. The operation steps for positioning the swashplate body 1 are simple, and the positioning time is greatly shortened.

[0020] The positioning component 2 includes a support plate 21. The lower surface of the support plate 21 is fixedly connected to the swashplate body 1. The upper surface of the support plate 21 is fixedly connected to a positioning plate 22 for use with the swashplate seat 4. The swashplate seat 4 is movably engaged with the positioning plate 22. The inner side of the positioning plate 22 matches the outer side of the swashplate seat 4. The positioning plates 22 are arranged in a ring array. The close fit shape design and the ring array distribution allow the positioning plates 22 to engage the swashplate seat 4 from multiple points. The cross-sectional shape of the positioning plate 22 is arc-shaped. The arc design fits the outer contour of the swashplate seat 4 better, further optimizing the contact effect with the swashplate seat 4.

[0021] A retaining plate 26 is fixedly connected to the upper surface of the support plate 21. The retaining plate 26 and the swashplate seat 4 are movably connected to a positioning pin 27. The retaining plate 26 provides a stable mounting position for the positioning pin 27. A slot 23 is provided on the outer side of the swashplate seat 4 to cooperate with the positioning pin 27. One end of the positioning pin 27 passes through the positioning plate 22 and is movably connected to the slot 23, forming a stable connection system between the positioning plate 22, the positioning pin 27, and the swashplate seat 4. This restricts the movement of the swashplate seat 4 from multiple dimensions. Furthermore, the positioning pin 27... A positioning bolt 24 is threadedly connected to the upper surface of the card holder 26. The upper surfaces of both the card holder 26 and the positioning pin 27 are provided with a first screw hole 25 and a second screw hole 28 for use with the positioning bolt 24. The positioning bolt 24 is threadedly connected to the first screw hole 25 and the second screw hole 28. By tightening the threads, the positioning pin 27 is firmly fixed on the card holder 26, which simplifies the positioning structure of the swashplate and thus effectively improves the positioning efficiency of the compressor swashplate.

[0022] The auxiliary positioning mechanism 3 comprises an electric push rod 32 fixedly installed in the inner cavity of the swash plate body 1, and the output end of the electric push rod 32 is fixedly connected with a mounting plate 31, so as to facilitate the movement of the electric push rod 32 to drive the movement of the mounting plate 31.

[0023] The lower surface of the mounting plate 31 is dampedly rotationally connected with a pressing plate 33, and the damped rotationally connected mode enables the pressing plate 33 to be flexibly adjusted in angle to better fit the surface of the swash plate seat 4, so that the movement of the mounting plate 31 drives the pressing plate 33 to tightly press the swash plate seat 4, and the swash plate seat 4 is further positioned.

[0024] Working principle: firstly, the positioning assembly 2 enables the swash plate seat 4 to smoothly preliminarily movably connect along the positioning plate 22, preliminarily limits the swash plate seat 4 from the circumferential direction, and guides the swash plate seat 4 to quickly approach the predetermined center position and limit the radial displacement thereof.

[0025] At the same time, the positioning pin 27 is movably inserted between the two, and the outer side surface of the swash plate seat 4 is accurately accommodated with one end of the positioning pin 27, the end penetrates through the positioning plate 22 and is tightly inserted into the insertion groove 23, thereby preliminarily axially positioning the swash plate seat 4 and preventing the swash plate seat 4 from moving along the axial direction.

[0026] Then, the positioning screw 24 is tightly matched with the first screw hole 25 and the second screw hole 28, so that the positioning screw 24 is firmly fixed, and the stability of the entire positioning assembly 2 is further strengthened, thereby ensuring that the swash plate seat 4 will not be easily loosened after preliminary positioning.

[0027] After the preliminary positioning is completed, the auxiliary positioning mechanism 3 is started, the electric push rod 32 is started, the output end of the electric push rod 32 pushes the mounting plate 31 to move downward, and due to the damping characteristic, the angle can be flexibly adjusted during the movement according to the actual surface shape of the swash plate seat 4, so as to ensure the close fit.

[0028] The mounting plate 31 drives the movement of the pressing plate 33, so that the lower surface of the pressing plate 33 is closely fitted with the upper surface of the swash plate seat 4, the swash plate seat 4 is further positioned, and the automobile air conditioner compressor can be efficiently and reliably operated.

[0029] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technologies thereof, the present application also intends to include these modifications and variations.
