Description
Technical field
The utility model relates to field of air conditioning, particularly a kind of air condition compressor reservoir.
Background technology
Existing air condition compressor reservoir generally has two kinds of structures: one is socketed successively by upper end cover 1 ', cylindrical shell 2 ' and bottom end cover 3 ' and forms; One is socketed by upper shell and lower shell and forms.
Upper end cover 1 ', bottom end cover 3 ' need to be socketed with cylindrical shell 2 ' upper and lower port interference fit respectively, and the faying surface of socket place is bonded to each other, and required precision is higher.But cylindrical shell 2 ' is welded by sheet material is curling, because manufacture craft limit, cylindrical shell 2 ' cross section is difficult to the positive circle of standard of making, and has certain roundness tolerance; And upper end cover 1 ' and bottom end cover 3 ' are by mould molding, circularity is relatively better, therefore when upper end cover 1 ', bottom end cover 3 ' are socketed with cylindrical shell 2 ' upper and lower port interference fit respectively, is often difficult to assembling.
For addressing this problem, as shown in Fig. 1, Figure 1A, Figure 1B, existing way the port edge of to be socketed two parts is carried out large chamfering (be different from little chamfering, general flash removed chamfering is carried out to port be called little chamfering, do not consider the impact that circularity fluctuates, within the inclination angle of little chamfering and the gap of outer wall of the parts being socketed on the inside are about 0.3mm), make the external diameter of each port edge diminish and internal diameter becomes large, thus avoid the impact of circularity, be conducive to assembling.But this mode is only applicable to filler welding (such as crossing stove weldering etc.), for the self-melt welding not adding solder/welding wire, welding effect is not good.Trace it to its cause, mainly because after the port socket of chamfering, the inclination angle being socketed on the component port chamfering place of outside just can form certain interval 4 ' with the outer wall of the parts being socketed on the inside, because cylindrical shell cross section right and wrong are just circular, can cause the chamfering amount of each point of barrel port all possibility is different when chamfering cylindrical shell, therefore cause the aforementioned gap 4 ' that circumferentially distributes not of uniform size, the large some places of some places are little, change does not have systematicness and uncontrollable, the difficulty controlling welding gun accuracy when adopting self-melt welding is increased, and this gap 4 ' distance is comparatively large (even if need not consider the impact that circularity fluctuates, maximal clearance also may be greater than 1mm), when using filler welding, this gap 4 ' can be filled by filler, but as adopted self-melt welding, only fill by mother metal melting, and welding is generally at the uniform velocity carried out, with regard to being easy to, such gap 4 ' occurs that the part of mother metal melting is not enough to fill gap 4 ' apart from large position, there is the phenomenon of solder skip (without material joint filling).
Summary of the invention
