Abstract
The utility model provides a bent axle formula compressor cylinder structure, includes cylinder body and cylinder liner, aforesaid cylinder body has a jar hole, the cylinder liner to locate this jar downthehole, its characterized in that cylinder liner and cylinder body be clearance fit, the shaping of cylinder liner one end have a flange portion, this flange portion one side has one and levels the terminal surface, and correspondingly, the jar hole of cylinder body have one with the step portion of aforementioned flange portion adaptation, this step portion one side have with the aforementioned terminal surface matched with installation region of leveling. Compared with the prior art, the utility model has the advantages of: the cylinder liner can imbed the cylinder body by hand, need not the press and impresses and subsequent junction of the edges of two sheets of paper round pin of beating, has reduced the precision influence that the press effect brought, and assembly simultaneously is simple reliable more.
Description
Technical field
This utility model relates to the cylinder body of a kind of crankshaft compressor and assembles structure with cylinder sleeve.
Background technology
Crank type connecting rod compressor is a kind of common compressor, and such compressor mainly includes cylinder body, valve board assembly, cylinder cap, protecgulum, bonnet, bottom and bent axle, and the casing of cylinder body forms build-in cavities and has cylinder holes, lower port, front port and rear port；Valve board assembly is arranged at the cylinder holes of casing by cylinder cap from the outside to the core, protecgulum, bonnet and bottom are respectively arranged in the front port of cylinder body, rear port and lower port, front crankshaft extends transversely through in being arranged at the build-in cavities of cylinder body and two ends and stretches out front port and rear port, is wherein provided with cylinder sleeve in the cylinder holes of cylinder body.
At present, cylinder sleeve is Thin-walled Straight tubular, and cylinder body is machined with cylinder holes, and cylinder holes is equal with cylinder sleeve external diameter, and the cylinder holes degree of depth is equal to cylinder sleeve length, and cylinder sleeve offers semicircle spacing breach, and breach bottom surface is parallel with cylinder face.Cylinder sleeve and cylinder holes are interference fit, are typically pressed into press, be connected end hole at cylinder sleeve and cylinder body, squeeze into junction of the edges of two sheets of paper pin and prevent cylinder sleeve rotation after press-in.
Above-mentioned cylinder body needs use press device for pressing cylinder liner and bore junction of the edges of two sheets of paper pin technique with the assembling structure of cylinder sleeve, cylinder body can be produced certain deformation, affect cylinder precision.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of to assemble, for the above-mentioned state of the art, the crankshaft compressor housing structure that convenient and precision is not affected by assembling.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is: a kind of crankshaft compressor housing structure, including cylinder body and cylinder sleeve, aforesaid cylinder body has cylinder holes, described cylinder sleeve is located in this cylinder holes, it is characterized in that described cylinder sleeve and cylinder body are matched in clearance, further, described cylinder sleeve one end forms a flange portion, and this flange portion side has a flat end face；Accordingly, the cylinder holes of described cylinder body has a stage portion adaptive with foregoing flange portion, and this stage portion side has the installation region matched with aforementioned flat end face.
Further, described flange portion outer face and the outer face of cylinder body cylinder holes keep smooth.
Described cylinder holes is at least two, and is arranged side by side, and described cylinder body forms connecting portion between adjacent cylinder holes, and the flat end face of described flange portion is close to connecting portion and arranges, and, the flat end face of adjacent described flange portion fits.Adjacent cylinder sleeve can be made to obtain each other the most spacing.
The middle part of described connecting portion is formed with an axial gap.Axial gap can reduce cylinder body forming requirements, and the assembling of the most adjacent cylinder sleeve is very clear, prevents neglected loading.
Compared with prior art, the utility model has the advantage of: cylinder sleeve can embed cylinder body by hand, it is not necessary to press press-in and follow-up beats junction of the edges of two sheets of paper pin, decreasing the precision that press effect brings affects, assemble simultaneously simpler reliably.

Fig. 1 is example structure schematic diagram.
Fig. 2 is the structural representation after removing a cylinder sleeve in Fig. 1.
Fig. 3 is the enlarged drawing of cylinder sleeve in Fig. 1.
Fig. 4 is embodiment partial sectional view.
Fig. 5 is the structural representation after removing adjacent two cylinder sleeves in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As depicted in figs. 1 and 2, crankshaft compressor housing structure includes cylinder body 1 and cylinder sleeve 2, and cylinder body 1 has four cylinder holes 11, is arranged symmetrically with two-by-two.Cylinder sleeve 2 is located in this cylinder holes 11, and cylinder sleeve 2 and cylinder body 1 are matched in clearance.
Shown in Fig. 3 and Fig. 4, cylinder sleeve 2 one end forms a flange portion 21, and this flange portion 21 side has a flat end face 22；Flange portion outer face and the outer face of the cylinder holes 11 of cylinder body keep smooth.The cylinder holes 11 of cylinder body 1 has the stage portion 14 of one and flange portion 21 adaptation, and this stage portion 14 side has the installation region matched with flat end face 22.It is freely rotatable in cylinder holes 11 that flat end face 22 can limit cylinder sleeve 2.
Shown in Fig. 5, cylinder body 1 forms connecting portion 12 between adjacent cylinder holes 11, and the middle part of connecting portion 12 is formed with an axial gap, and the flat end face 22 of flange portion 21 is close to connecting portion 12 and arranges, and, the flat end face 22 in adjacent flanges portion 21 fits.The middle part of connecting portion 12 is formed with an axial gap 13.
