Technical Field
[0001] This utility model relates to the technical field of spindle swashplate structure, specifically a spindle swashplate structure for an automotive air conditioning compressor. Background Technology
[0002] The automotive air conditioning compressor is a key component for regulating the comfort of the vehicle's interior environment. Among them, the swashplate compressor is widely used due to its compact structure and high efficiency. As the core motion conversion component of this type of compressor, the dynamic balance performance of the swashplate directly affects the smoothness of compressor operation, vibration and noise levels, and overall lifespan.
[0003] The existing spindle swashplate structure is relatively complex and poorly designed. In actual use, since the swashplate is a high-precision integral rotating component, when the spindle swashplate is damaged, the entire swashplate assembly or compressor assembly must be replaced, which not only increases maintenance costs but also takes a lot of time and effort and is difficult to repair. To address this problem, the inventor designed a spindle swashplate structure for automotive air conditioning compressors. Utility Model Content

[0025] Please see Figures 1 to 4 The present invention provides an embodiment of a main shaft swashplate structure for an automotive air conditioning compressor, the main shaft swashplate structure comprising a main shaft 1, a swashplate 2, and an adjusting member 3; the swashplate 2 is disposed outside the main shaft 1, and the adjusting member 3 is disposed inside the swashplate 2;
[0026] The main shaft 1 is the core power input component, which carries and transmits the torque output by the engine to the swashplate 2. The swashplate 2 converts the rotational motion of the main shaft 1 into the reciprocating linear motion of the piston, which is the core conversion mechanism for the compressor to compress the refrigerant.
[0027] The adjusting component 3 includes a connecting hole 31, a semi-ring 32, and a counterweight 33. The connecting hole 31 is opened inside the swash plate 2, and the connecting holes 31 are arranged in a circular array with the swash plate 2 as the center. There are a total of six sets of connecting holes 31. The semi-rings 32 arranged in opposite directions are arranged inside any set of connecting holes 31, and the counterweight 33 is engaged inside the opposite semi-rings 32.
[0028] The connecting hole 31 provides a mounting carrier for the counterweight 33, allowing for flexible adjustment of mass distribution in multiple positions. The semi-ring 32 forms a positioning slot for the counterweight 33, limiting its radial displacement. The counterweight 33 can accurately compensate for the lost mass, allowing the center of mass of the swashplate 2 to return to its axis of rotation.
[0029] The counterweight 33 has guide grooves 34 on both sides, and the guide grooves 34 are square in shape;
[0030] The guide groove 34, in conjunction with tweezers, enables precise positioning of the counterweight 33, simplifying assembly operations in confined spaces.
[0031] Connecting posts 36 are fixed on both sides inside the connecting hole 31, and the connecting posts 36 are located on the outside of the guide groove 34;
[0032] The connecting post 36 supports the connecting tube 37 and provides the threaded engagement base of the screw 39;
[0033] A connecting tube 37 is sleeved on the outer surface of the connecting post 36;
[0034] The connecting pipe 37 wraps around the connecting post 36 and is integrated with the cover plate 35, which prevents impurities from entering the connecting hole 31 while improving the structural rigidity.
[0035] A cover plate 35 is fixed to the outer surface of the connecting pipe 37, and the cover plate 35 is completely housed inside the connecting hole 31.
[0036] The cover plate 35 closes the opening of the connection hole 31, protecting the internal components from contamination;
[0037] Mounting holes 38 are provided on both sides of the cover plate 35, and the cross-section of the mounting holes 38 is convex.
[0038] Mounting hole 38 allows the head of screw 39 to be recessed therein, keeping the outer surface of cover plate 35 flat;
[0039] A screw 39 is provided inside the mounting hole 38, and the screw 39 is threaded into the inside of the connecting post 36;
[0040] Screw 39 locks the cover plate 35 and the counterweight 33 to ensure that the adjusting part 3 will not loosen under dynamic working conditions;
[0041] Working principle: During the use of the spindle swashplate, the vibration spectrum is monitored by a six-degree-of-freedom accelerometer to detect the rotational mass of the swashplate 2 after damage. When excessive damage is detected in a certain part of the swashplate 2, the screw 39 is first removed from the inside of the cover plate 35, and then the cover plate 35 is removed from the inside of the connecting hole 31. Then, depending on the wear condition, tweezers are placed inside the guide groove 34, and the counterweight 33 can be easily placed between the semi-rings 32. After the counterweight 33 is installed, the connecting tube 37 is inserted into the outside of the connecting post 36, and then the screw 39 is placed inside the mounting hole 38. A rotational force is applied to the screw 39 to turn it into the connecting post 36, thereby achieving the operation of adjusting the rotational mass.
[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
