The basic structure of the cylinder block of hermetically sealed compressor is, its stator attachment face is to be distributed on the four jiaos of stator installation bases in cylinder block lower end surface, promptly constitute (referring to Fig. 1, Fig. 2) by four stator faces 8,9,10,11, these four stator faces are used for the supporting motor stator.But when processing stator face, be so that to clamp table tops be clamping point in three set on cylinder block processing location and process locating basis and process, it is vital to the influence of the planeness of stator attachment face that these three clampings are put reasonable Arrangement how.
The cylinder block of existing hermetically sealed compressor (referring to Fig. 1,2), when design clamping point and processing locating basis, its distribution situation of 3 is, two clamping points 5,6 are arranged in cylinder head 12 both sides (being two the stator installation bases of cylinder block near head), and clamping point 7 of cylinder block afterbody (cylinder-bore offside) intermediate arrangement, and this point generally is the symmetric points of cylinder block afterbody two stator face screw holes 3,4.This structure produces adverse influence to the machining meeting.Hermetically sealed compressor cylinder block structural feature is, the thickness of cylinder head 12 sides is bigger, and its intensity is very high, and owing to the reason of considering cost and configuration aspects, the thickness of cylinder block afterbody cast iron often designs not quite, and its intensity can not show a candle to the intensity of cylinder head side.When processing stator face, two stator faces of cutting cylinder block afterbody 10,11 o'clock, because machining allowance is big, cutting force is big, rebound deformation is big.The big main unfavorable factor by two aspects of amount of deformation is caused: on the one hand, the strength deficiency of cylinder block afterbody, on the other hand, the distance of the point of action of cutting force and locating point 7 is bigger, the arm of force is big, this has just determined that the distortion bounce-back of these afterbody two stator faces 10,11 is bigger, thereby has influence on the planeness of stator attachment face.
(3) summary of the invention:
The purpose of this utility model is that will to solve the clamping point layout of existing cylinder block processing stator attachment face unreasonable, causes machining deformation easily, and the problem that machining accuracy is difficult to guarantee provides a kind of cylinder block that improves the machining accuracy hermetically sealed compressor.
Concrete scheme of the present utility model is: improve at existing cylinder block, the utility model cylinder block, design has cylinder head on it, its lower end surface is furnished with four stator installation bases for four jiaos, it is characterized in that: near two stator installation base roots design of afterbody two processing positioning and clamping table tops are arranged at cylinder block, and be the 3rd processing positioning and clamping table top with cylinder head.
Be compact structure, stressed more reasonable, the processing positioning and clamping table top near the stator installation base described in the utility model is to arrange by the inboard or the rear side of location and installation boss root.
Improvement main points of the present utility model: be that the processing positioning and clamping table top that will design originally on two stator installation base next doors of cylinder block head moves to two stator installation base next doors of cylinder block afterbody, and as first, second clamping point and processing locating basis point, and the processing positioning and clamping table top that will design originally in the middle of the cylinder block afterbody is cancelled, and the cylinder head that directly adopts cylinder block is the 3rd clamping point and processing locating basis point.
Improvement structure of the present utility model can guarantee that the machining deformation amount of stator attachment face is little, and planeness is good, thereby can improve the machining accuracy of each size of cylinder block and position degree.

(5) embodiment:
Referring to Fig. 3, Fig. 4, the utility model cylinder block has the basic structure (slightly changing in shape with the existing cylinder block of Fig. 1) of common cylinder block.This cylinder block head design has cylinder head 13, there is axis hole 22 centre, there is limited post 25 both sides, afterbody upper end, and it is four stator faces 18,19,20,21 that the four jiaos of designs in the lower end of cylinder block have four stator installation bases 14,15,16,17, the exterior edge face of these four boss.Particularly: in the utility model, design has two processing positioning and clamping table tops 23,24 near the root (inboard) of two stator installation bases of afterbody 14,15; And be the 3rd processing positioning and clamping table top with cylinder head.
Design principle contrast Fig. 3, Fig. 4 of the present utility model are further described: the utility model cylinder block, be near two stator installation base 14,15 places a processing positioning and clamping table top 23,24 to be set respectively at the more weak cylinder block afterbody of intensity, its upper and lower end face is respectively clamping point and processing locating basis point, and with intensity preferably cylinder head 13 forms three clamping points and processes the locating basis point as the 3rd processing positioning and clamping table top.The zone of the processing locating basis point 13 of cylinder head side between cylinder head both sides stator face 20,21, when processing stator face, although machining allowance is big, cutting force is big, two stator faces 20,21 are bigger apart from the distance of locating basis point 13, but because the casting thickness at cylinder head place is big, its intensity is enough high, so stator face 20,21 distortion of cylinder head both sides are minimum.And two locating basis points 23,24 of cylinder block afterbody lay respectively at the next door of two stator installation bases 14,15, very near apart from the distance of two stator faces 18,19 respectively, compare with locating basis point 7 of cylinder block afterbody layout of existing design, distance is much closer, like this, because locating basis point 23,24 two stator faces, 18,19 distances with the processing cutting respectively is very little, although machining allowance is big, cutting force is big, but make the moment of workpiece processing distortion very little, the distortion rebound amount of two stator faces 18,19 is minimum.This shows, adopt the cylinder block of the utility model structure, constitute the stator attachment face the machining deformation amount of four stator faces 18,19,20,21 minimum, thereby the planeness that guarantees the stator attachment face is fine.And the relative dimensions of follow-up processing is that benchmark is processed with this stator attachment face all, therefore, the utlity model has the good stator attachment face of planeness and provide reliable assurance, thereby improve the machining accuracy of each size of cylinder block and position degree for the position degree of the relative dimensions of following process.
