Description

Technical Field

[0001] This invention relates to the field of replacement technology for PXE slide plates in compressors, specifically a replacement mechanism for PXE slide plates in automotive air conditioning variable displacement compressors. Background Technology

[0002] The compressor uses a swashplate and sliding shoes mounted on the drive shaft within the crankshaft cavity to convert the rotation of the drive shaft into the reciprocating motion of the piston in the cylinder bore, thereby compressing the gas. A pair of sliding shoes, acting as sliding components, are positioned between the swashplate and the piston to ensure smooth operation. During operation, the swashplate often heats up due to high-speed movement, leading to damage to the sliding shoes, requiring timely replacement.

[0003] Existing sliding shoe replacement methods typically involve manually disassembling and replacing the compressor, resulting in low work efficiency. Furthermore, the compressor contains a large amount of lubricating oil and toxic impurities, which are difficult to clean effectively from workers' skin and can easily cause skin ulcers, posing a safety hazard. If the replaced sliding shoe is not cleaned in time, the toxic impurities on its surface can easily diffuse into the air, causing pollution. Therefore, a sliding shoe replacement mechanism for PXE variable displacement compressors in automotive air conditioning systems is proposed to solve this problem. Summary of the Invention

This mechanism offers advantages such as easier installation of the sliding track and timely cleaning of the replaced track. It solves the problems of existing sliding track replacement methods, which typically involve manually disassembling and replacing the compressor, resulting in low work efficiency. Furthermore, the compressor contains a large amount of lubricating oil and toxic impurities, which are difficult to clean effectively from workers' skin and can easily cause skin ulcers, posing a safety hazard. Additionally, if the replaced track is not cleaned promptly, the toxic impurities on its surface can diffuse into the air, causing pollution.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a replacement mechanism for the PXE sliding track of an automotive air conditioning variable displacement compressor, which has the following advantages:

[0015] 1. The replacement mechanism for the PXE sliding track of the automotive air conditioning variable displacement compressor consists of a replacement component and a cleaning component. The spring and rope shaft facilitate the removal of the sliding track replacement equipment. The cleaning fluid inside the cleaning chamber cleans the replacement equipment and the replacement sliding track. Ultraviolet light provides disinfection. The heating plate in the drying chamber dries the equipment and prevents toxic cleaning fluid from being released into the air. The oil-absorbing cotton in the cleaning component absorbs the lubricating oil inside the sliding track. The limit box prevents lubricating oil from leaking out when the replacement equipment is removed. The clamps and baffles on the replacement component allow the sliding track to be removed.

[0016] 2. The replacement mechanism for the PXE sliding track of the automotive air conditioning variable displacement compressor involves a cleaning component that uses an electric telescopic rod to deliver oil-absorbing cotton into the through hole of the sliding track. A motor drives the cotton to rotate, allowing it to better absorb lubricating oil. The electric telescopic rod then retracts the cotton into the limit box to prevent lubricating oil leakage. The replacement component uses a pressing button to retract a spring, which in turn clamps the clamping plate via a helical spring, allowing it to be inserted into the through hole. Releasing the button secures the sliding track with the baffle and clips, allowing it to be removed. A storage slot allows for better storage of the replacement equipment when not in use. A threaded cap allows for easier access to the inlet and outlet for convenient replacement and recycling of the cleaning fluid. The friction layer provides better ease of use for workers and prevents slippage. Attached Figure Description

Then, the electric telescopic rod 703 retracts the oil-absorbing cotton into the limit box 704. The limit box 704 prevents lubricating oil from flowing out when the equipment is removed for replacement.

[0031] In summary, the replacement mechanism for the PXE variable displacement compressor sliding track of this automotive air conditioning system consists of a replacement component 6 and a cleaning component 7. First, the spring 18 and the winding shaft 3 facilitate the retrieval of the sliding track replacement equipment. Then, the equipment is cleaned with cleaning fluid inside the cleaning chamber 9, disinfected with ultraviolet light 17, and dried by the heating plate 11 inside the drying chamber 9. Finally, the cleaning component 7 absorbs the lubricating oil inside the sliding track. The cleaning component 7 uses an electric telescopic rod 703 to deliver oil-absorbing cotton 705 into the through-hole of the sliding track. The motor 702 drives the oil-absorbing cotton 705 to rotate, thereby effectively absorbing the lubricating oil. Then, the electric telescopic rod 703 retracts the oil-absorbing cotton into the limit box 704. The limit box 704 prevents the lubricating oil from flowing out when the replacement equipment is removed. Then, the sliding shoe is removed and replaced by the replacement component 6. The replacement component 6 compresses the spring 606 by pressing the button 607, thereby clamping the clamping plate 602 through the helical spring 605 and sending it into the through hole. By releasing the button 607, the baffle 603 and the buckle 604 fix the sliding shoe, thereby removing the sliding shoe for replacement.
