Abstract
The utility model discloses a fracture type splitting connecting rod for a compressor, comprising a connecting rod big end, a connecting rod small end and a connecting piece, and the connecting rod big end and the connecting rod small end are formed by cutting a whole connecting rod under the action of external force, a V-shaped fracture groove is formed at the fracture position of the connecting rod big end, a V-shaped locating bulge is formed at the fracture position of the connecting rod small end, and the connecting rod big end and the connecting rod small end are connected together by the connecting piece. By adopting the splitting connecting rod in the utility model, a connecting rod assembling demising notch is not needed to be arranged on an air cylinder hole of a crankcase when the compressor is assembled, so as to avoid deformation caused by the notch, the stability of the performance of the compressor is improved, and the manufacturing cost of the splitting connecting rod is lowered as well.
Description
Technical field
The utility model relates to a kind of bar linkage structure that is applied to refrigeration compressor.
Background technique
Reciprocating type bent axle-the linkage mechanism of the general employing of existing hermetically sealed compressor, as shown in Figure 1, it comprises bent axle 1, connecting rod 2, crankcase 3, piston 4 and wrist pin 5, piston 4 is installed in the cylinder-bore of crankcase 3, is connected with connecting rod 2 by wrist pin 5.During compressor operating, bent axle 1 rotates, and it is reciprocating to drive piston 4 by connecting rod 2.Because the connecting rod 2 general overall structures that adopt in order to ensure carrying out smoothly of assembling, need to design a connecting rod breach 6 of stepping down are installed on the cylinder-bore of crankcase 3.Like this, not only increase processing cost, and caused the distortion of cylinder-bore easily, thereby caused the decline of compressor performance.For this reason, the claimant has designed a kind of split bar linkage structure, and as shown in Figure 2, its structure comprises connnecting rod big end 7, connecting rod small end 8 and connecting pin 9.Its mounting type is as shown in Figure 3: at first connnecting rod big end 7 is installed on the bent axle 1, then connecting rod small end 8, piston 4 and wrist pin 5 are mounted to an assembly, then the V-arrangement positioning convex 11 of connecting rod small end 8 is assembled on the V-arrangement positioning groove 10 of connnecting rod big end 7, at last connecting pin 9 is installed to connection pin-and-hole 12 and is connected pin-and-hole 13.Therefore, need not to be provided with connecting rod on the cylinder-bore of crankcase 3 breach of stepping down is installed, avoided because of the cylinder-bore distortion problem that breach causes is set.But also there is shortcoming in the structure of this split connecting rod: connnecting rod big end 7 need be shaped on different moulds with connecting rod small end 8, and manufacture cost is higher; Simultaneously, for guaranteeing the parallelism of assembling back link major part and connecting rod small end, V-arrangement positioning convex 11 and V-arrangement positioning groove 10 need very high accuracy of manufacturing height, and difficulty is big, the cost height.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of compressor with breaking type split connecting rod, connecting rod not only need not be set on the cylinder-bore of crankcase the breach of stepping down is installed, thereby can avoid the distortion that causes thus, improves the stability of compressor performance; But also can reduce the manufacture cost of split connecting rod.
For solving the problems of the technologies described above, the utility model compressor comprises connnecting rod big end, connecting rod small end and link with breaking type split connecting rod, described connnecting rod big end and connecting rod small end are to be broken to form under the effect of external force by a monolithic linkage part, described connnecting rod big end forms V-arrangement fracture groove in fracture place, described connecting rod small end forms the V-arrangement positioning convex in fracture place, and described link links together described connnecting rod big end and connecting rod small end.
Above-mentioned compressor breaking type split connecting rod, described link is a jump ring, and described connnecting rod big end and connecting rod small end are provided with the location and installation groove of mutual correspondence, and described jump ring snaps in described location and installation groove, and described connnecting rod big end is connected the location with connecting rod small end.
Above-mentioned compressor also vertically is provided with arc groove respectively with breaking type split connecting rod on the sidewall of described connnecting rod big end and connecting rod small end, described jump ring inserts in the described arc groove.
The utility model during manufacturing, is provided with earlier V-arrangement breaking groove and location and installation groove owing to adopt technique scheme on the connecting rod of monolithic linkage.Pull by external force then, make monolithic linkage naturally separately, become breaking type split connecting rod, form the connnecting rod big end of band V-arrangement positioning groove and the connecting rod small end of band V-arrangement positioning convex respectively at V-arrangement breaking groove place.Like this, just do not need to design a connecting rod on the cylinder-bore of compressor crankcase the breach of stepping down is installed, avoided the distortion that causes thus, improve the stability of compressor performance, also reduced the manufacture cost of connecting rod simultaneously.Because V-arrangement positioning groove and V-arrangement positioning convex form when breaking naturally, thereby have good assembly performance, can guarantee required precisions such as connecting rod two hole parallelism after the assembling.The Placement of jump ring and location and installation groove and jump ring and arc groove, the connnecting rod big end of being more convenient for is connected with dismounting between connecting rod small end.

Embodiment
As shown in Figure 4, the utility model compressor adopts overall structure with breaking type split connecting rod before fracture, comprises connnecting rod big end 7 and connecting rod small end 8, can be shaped on a secondary mould, and manufacture cost is lower.
As shown in Figure 5, the utility model compressor is provided with location and installation groove 16, location and installation groove 17, breaking groove 20 and hole 21 with breaking type split connecting rod before fracture, and location and installation groove 17 is provided with arc groove 18 and arc groove 19.Under the effect of external force F1 and F2, monolithic linkage disconnects at breaking groove 20 places, is separated into a connnecting rod big end 7 and a connecting rod small end 8.As shown in Figure 6, post-rift connnecting rod big end 7 forms a V-arrangement positioning groove 23 at breaking groove 20 places, post-rift connecting rod small end 8 forms a V-arrangement positioning convex 22 at breaking groove 20 places, because V-arrangement positioning groove 23 and V-arrangement positioning convex 22 form when breaking naturally, assembly performance is good, can guarantee required precisions such as connecting rod two hole parallelism after the assembling.
Being illustrated in figure 7 as the utility model compressor is assembled on the V-arrangement positioning groove 23 of connnecting rod big end 7 at post-rift mounting type: a, the V-arrangement positioning convex 22 of connecting rod small end 8 with breaking type split connecting rod; B, insert location and installation grooves 16 with a jump ring 25; C, insert arc groove 18 and arc grooves 19 with two jump rings 24.
In the utility model structure, also can adopt other Placement except that jump ring-location and installation groove-arc groove that connnecting rod big end 7 is positioned with connecting rod small end 8 and be connected, as adopting Fig. 2 and connecting pin-positioning hole mode shown in Figure 3.Because the utility model compressor can be shaped on a secondary mould with breaking type split connecting rod, manufacture costs such as equipment investment, personnel's configuration, die cost have obvious decline.
