Abstract
The utility model relates to a novel vortex automobile air conditioning compressor, wherein a movable vortex disc component (4) and a fixed vortex disc (6) in the compressor are assembled and then arranged in a lower shell (7); a bearing pedestal component (3) is arranged in a motor shell (2) through a corresponding screw; the novel vortex automobile air conditioning compressor is characterized in that one to two positioning pins (8) are arranged on the rear end face of the fixed vortex disc, wherein the positioning pins (8) are matched with positioning holes which are formed in an end face of an inner hole of the lower shell (7) for rotation stopping and positioning. Flange faces of the motor shell and the lower shell are provided with one to two corresponding positioning pin holes (9) and positioning pins (10) respectively, so that the relative position for assembly of the motor shell and the lower shell is guaranteed. The novel vortex automobile air conditioning compressor has the effects that since the front end face of the fixed vortex disc and the end face of the hole of the lower shell are matched in a rotation stopping manner by using the positioning pins, positioning and assembly are performed through positioning pin holes in the flange faces of the motor shell and the lower shell, the overall assembly accuracy of the compressor is guaranteed, the assembly efficiency is increased, and meanwhile, the parts have simple structures, are light in weigh and convenient to machine.
Description
Technical field
The utility model relates to the vortex type automobile air conditioner compressor of the compressor in the machinery field, particularly a kind of new structure.
Background technique
The key job part of scroll compressor is dynamic and static scroll and its assembly precision; Motor assembly on the electric machine casing (bent axle) drives moving scroll by carrying out translating revoluting around fixed scroll according to certain radius; Intermesh with fixed scroll; And need to guarantee 180 ° phase relationship, this is the primary condition that dynamic and static scroll realizes proper functioning.Dynamic and static scroll all is to be respectively charged in bearing support, the lower shell body according to certain phase relationship, and electric machine casing, just needs to continue to guarantee 180 ° of phase relationships of dynamic and static scroll when lower shell body attaches together.This existing technology that attaches together is on electric machine casing, lower shell body flanged surface, to attach together through 6～8 screws and increase bearing support fitting surface.The method has increased the processing and the assembling difficulty of bearing support, attaches together precision and cannot say for sure card, and is simultaneously consuming time, waste wood efficient is low, and needing therefore that exploitation is a kind of can weight reduction, processing easily again, new structure easy for installation.
The model utility content
The purpose of the utility model is exactly for processing that solves existing vortex type automobile air conditioner compressor complex structure, part and the big shortcoming of assembling difficulty, a kind of novel scroll formula automobile air conditioner compressor that provides.
The technological scheme that the utility model adopts is:
A kind of novel scroll formula automobile air conditioner compressor; Form by electric machine casing, lower shell body, moving scroll parts, fixed scroll, bearing block assembly, motor assembly; Be installed in the lower shell body after moving scroll parts and the fixed scroll assembling; Bearing block assembly is contained in the electric machine casing through the screw of correspondence; It is characterized in that: the fixed scroll ear end face is provided with 1-2 locating stud, in lower shell body, is provided with the positioning hole with the locating stud corresponding matching on the hole end surface, and the fixed-site that makes fixed scroll is in lower shell body.
On the basis of technique scheme, further technological scheme is arranged:
On the flanged surface of electric machine casing, lower shell body, be respectively equipped with the positioning pin hole of 1～2 correspondence, be provided with locating stud in the positioning pin hole, to guarantee the relative position of electric machine casing, lower shell body assembling.
Guarantee itself and electric machine casing endoporus end face axial size through fixed scroll front-end face location, the axially locating precision of realization complete machine.
The effect of the utility model is: carry out spline owing to spline hole on locating stud and the lower shell body hole end surface on employing fixed scroll front-end face location and the ear end face attaches together; Position, assemble through positioning pin hole on the flanged surface of electric machine casing, lower shell body; Guaranteed compressor final assembly precision; Improved efficiency of assembling, design of part is simple, in light weight, easy to process simultaneously.

Embodiment
As shown in Figure 1; A kind of novel scroll formula automobile air conditioner compressor that the utility model provides; Form by electric machine casing 2, lower shell body 7, moving scroll parts 4, fixed scroll 6, bearing block assembly 3, motor assembly 1; Moving scroll parts 4 are installed in the lower shell body 7 after assembling with fixed scroll 6, and bearing block assembly 3 is contained in the electric machine casing through the screw of correspondence.Fixed scroll 6 end faces are provided with 1-2 locating stud 8, in lower shell body 7, are provided with the positioning hole 8a with the locating stud corresponding matching on the hole end surface, and the fixed-site that makes fixed scroll is in lower shell body 7.
Like Fig. 2, shown in Figure 3, in lower shell body 7, offer the positioning hole 8a of 1～2 locating stud on the hole end surface, it with insert on the fixed scroll parts ear end face locating stud 8 and fit into whereabouts and change.
In addition; Each only opens a positioning pin hole 9 (or tapped hole oral area pilot hole) on the flanged surface of electric machine casing 2 and lower shell body 7 respectively, at electric machine casing, when bottom shell component attaches together, sees Fig. 1; Top shell component is packed in the oral area hole of bottom shell component; Penetrate in the positioning pin hole 9 with a locating stud 10 then, make electric machine casing, bottom shell component keep the phase relationship of design, use several screws 5 will go up bottom shell component at last and fix and extract locating stud.
