Technical field
The utility model belongs to automobile air conditioner compressor technical field, and in particular to automobile air conditioner compressor vulcanization sealing knot
Structure.
Background technology
Automobile air conditioner compressor is the heart of automobile air conditioning refrigerating system, plays compression and conveys the work of refrigerant vapour
With.Automobile air conditioner compressor is divided into two kinds of immutable discharge capacity and variable displacement.According to the difference of operation principle, air conditioning for automobiles compresses
Machine can be divided into fixed displacement compressor and variable compressor.According to the difference of working method, automobile air conditioner compressor generally may be used
Reciprocating and rotary to be divided into, common reciprocating automobile air conditioner compressor has crankshaft connecting rod type and axial-piston, common
Rotary automobile compressor of air conditioner have orbiting vane and vortex.
For waterproof and dustproof, prevent other media from entering in automobile air conditioner compressor, automobile air conditioner compressor sealing structure
Design it is most important, as shown in Figure 1-Figure 3, existing sealing structure is made of cylinder body 1, gasket 2, cover board 3, wherein cylinder
Body 1, gasket 2, cover board 3 are three seperated components, and 1 end face of cylinder body opens up fluted in the position of cooperation, and gasket 2 is packed into
In groove, then it is packed into cover board 3 on gasket 2, cover board 3 is fixed by pilot hole 4 using trip bolt, it is close to realize
Envelope.
Although existing design of Sealing Structure is relatively simple, there are following defects：
1) assembling process generates gasket 2 effect of power, and gasket 2 is distorted deformation, is easy to happen damage and fails,
Cause poor sealing, generates functional defect；
2) it is made of three seperated components, component is more, and reliability is low, there is the risk of poor sealing；
3) groove need to be processed in 1 end face of cylinder body, difficulty of processing is big, of high cost；
4) using manually installed when gasket 2 is installed, efficiency is low, and difficulty is big.
Therefore, it is necessary to the sealing structures to automobile air conditioner compressor to be further improved, to prevent drawbacks described above.
Utility model content
The utility model aim is：It is intended to provide automobile air conditioner compressor vulcanization sealing structure, it is existing close to solve
The problems such as there are poor sealing, cylinder body Pocket Machining difficulty for seal structure design defect greatly, gasket installation effectiveness is low.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
Automobile air conditioner compressor vulcanizes sealing structure, including cylinder body and cover board, the cover inner surface are bonded in cylinder body
Position offer vulcanization step, the cover inner surface offers and the sealing that vulcanizes step and communicate on the inside of vulcanization step
Step, overlap is not more than 0.14mm, the gasket after vulcanization has gasket and vulcanizes at the vulcanization step and sealing step
In the position being bonded with cylinder body thickness be equal to vulcanization step and sealing step the sum of depth dimensions, the cylinder body and
Cover board is detachably connected by pilot hole.
Further, the sealing is padded on the surface contacted with cylinder body integrally formed with two circle seal convexities, to which composition is double
The height dimension of lip seal structure, the seal convexity is 0.5 ± 0.15 ㎜, and the section of the seal convexity is one third
The spacing dimension of circle, the two circle seal convexities is 0.4 ± 0.25 ㎜.Such design effectively controls cylinder body and is filled with cover board
The gasket axial deflection of timing.
The utility model compared with the prior art for, have the following advantages that：
1) gasket and cover board are vulcanized, and are combined into an entirety, and rigidity is relatively good, and gasket will not be distorted change
Shape, it is not easy to which the failure that is damaged causes poor sealing, ensures the functionality of product；
2) it is made of cylinder body and the seperated component of cover board two, component lacks reliability height, reduces the risk of poor sealing；
3) it is not necessarily to process slot in cylinder body end face, process without difficulty, cost substantially reduces；
4) work step is reduced, is mounted directly screw, production efficiency greatly improves, and operation difficulty is small.
