Abstract
The utility model relates to a connecting structure of a front cylinder and a rear cylinder of a double directional oblique-plate-type compressor, which comprises the front cylinder and the rear cylinder. The middles of the front cylinder and the rear cylinder respectively include a front spindle hole, a rear spindle hole. The connecting structure of the front cylinder and the rear cylinder of the double directional oblique-plate-type compressor also comprises a front spindle hole sleeve and a rear spindle hole sleeve. The front spindle hole sleeve is arranged on one side of the front spindle hole which is arranged on the front cylinder. The rear spindle hole sleeve is arranged on one side of the rear spindle hole which is arranged on the rear cylinder. The connecting structure of the front and the rear cylinder of the double directional oblique-plate-type compressor has the advantages of ensuring coaxiality of the two spindle holes of the front cylinder and the rear cylinder, lowering processing requirements, lowering production cost and improving production efficiency.
Description
Technical field
The utility model relates to a kind of automobile air conditioner compressor, relates in particular to the front and back cylinder body linkage structure of this compressor.
Background technique
Fig. 1 is the internal structure schematic representation of two-way tilted-plate compressor.As seen from Figure 1: when main shaft 1 rotation, drive swash plate 2 rotations, make front-rear reciprocation movement in the cylinder hole of piston 5 in front-bank rotor housing 3 and rear-bank rotor housing 4, thereby in cylinder body, produce pressurized gas;
In such compressor arrangement, the forward spindle hole 31 of the front-bank rotor housing 3 and back spindle hole 41 of rear-bank rotor housing 4 is the step hole structure and concentricity requirement is very high.
Mainly be the above requirement of incompatible assurance that matches of 43 two pin holes of back pin hole of preceding pin hole 33 by front-bank rotor housing 3 and rear-bank rotor housing 4 and pin 6 in the prior art.But do not reach usage requirement because of cumulative errors such as processing, anchor clamps easily cause, make the processing cost of compressor high.
Summary of the invention
The utility model technical issues that need to address provide the linkage structure of a kind of two-way tilted-plate compressor front and back cylinder body, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: front-bank rotor housing and rear-bank rotor housing; Center at described front-bank rotor housing and rear-bank rotor housing comprises respectively: forward spindle hole and back spindle hole; Also comprise: at the forward spindle borehole jack on the described front-bank rotor housing, on one side of forward spindle hole; At the back main shaft borehole jack on the described rear-bank rotor housing, on spindle hole one side of back.
Compared with prior art, the beneficial effects of the utility model are: the concentricity of cylinder body two spindle holes before and after having solved, and processing request is reduced, thereby reduce production costs, enhance productivity.
Description of drawings
Fig. 1 is a two-way tilted-plate compressor structural representation in the prior art.
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: front-bank rotor housing 3 and rear-bank rotor housing 4; Center at described front-bank rotor housing 3 and rear-bank rotor housing 4 comprises respectively: forward spindle hole 31 and back spindle hole 41; Also comprise: at the forward spindle borehole jack 35 on the described front-bank rotor housing 3, on 31 1 sides of forward spindle hole; At the back main shaft borehole jack 45 on the described rear-bank rotor housing 4, on spindle hole 41 1 sides of back.
Described forward spindle borehole jack 35 and forward spindle hole 31 interference fit and back main shaft borehole jack 45 and back spindle hole 41 interference fit, magnitude of interference is 0.003-0.25mm.
The utility model increases by a main shaft borehole jack in the cylinder body of front and back, the spindle hole of cylinder body no longer is the step hole structure before and after making.After front and back cylinder body roughing is finished, the front and back cylinder body to be combined by the pin-and-hole hole, the employing machining center is disposable all to machine forward spindle hole and back spindle hole.The concentricity of cylinder body two spindle holes guarantees in compressor operation before and after having guaranteed like this, and is not loosening.
Can be on main shaft borehole jack and the cylindrical that spindle hole cooperates through annular knurl or other surface treatment to increase its fiting effect and to prevent the spindle hole distortion excessive.
In the compressor operation process, adopt the utility model to improve manufacturing efficiency, reduce production costs, solve the processing technique difficult problem of compressor critical component, reduce the rate of fault of compressor, prolong the life-span of compressor.
Claims (2)
1. the linkage structure of a two-way tilted-plate compressor front and back cylinder body comprises: front-bank rotor housing and rear-bank rotor housing; Center at described front-bank rotor housing and rear-bank rotor housing comprises respectively: forward spindle hole and back spindle hole; It is characterized in that: also comprise: at the forward spindle borehole jack on the described front-bank rotor housing, on one side of forward spindle hole; At the back main shaft borehole jack on the described rear-bank rotor housing, on spindle hole one side of back.
2. the linkage structure of cylinder body before and after the two-way tilted-plate compressor according to claim 1 is characterized in that: described forward spindle borehole jack and forward spindle hole interference fit and back main shaft borehole jack and back spindle hole interference fit, magnitude of interference is 0.003-0.25mm.
