(1) technical field: the present invention relates to completely closed piston reciprocating type refrigeration compressor component, is a kind of processing method of hermetically sealed compressor cylinder block.
(2) background technique: the stator attachment face of hermetically sealed compressor cylinder block (being used for installing the plane of motor stator) is the locating basis face of following process, its planeness has bigger influence to the position degree of following process relative dimensions, as five hole locations of stator attachment face the relative position of four screw holes that are used for installing stator (crankshaft hole with), two hole perpendicularities of crankshaft hole and cylinder-bore, cylinder end face five hole locations (relative position of four cylinder head screw holes and cylinder-bore), the perpendicularity of shaft shoulder face and axis hole etc. has bigger influence, and the quality of above several positions degree is to the Energy Efficiency Ratio of press, the influence of noise is bigger.Therefore, the planeness that how to improve the stator attachment face is the target that each compressor manufacturing company lays siege to.
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 clamping point layout that the objective of the invention is to solve existing cylinder block processing stator attachment face is unreasonable, causes machining deformation easily, and the problem that machining accuracy is difficult to guarantee provides a kind of processing method of hermetically sealed compressor cylinder block.
Concrete scheme of the present invention is: improve at existing cylinder block processing method, design has cylinder head on the cylinder block of the present invention, the cylinder block lower end surface is furnished with four stator installation bases for four jiaos, it is characterized in that:, and be the 3rd processing positioning and clamping table top with cylinder head at two processing of two the stator installation base roots design positioning and clamping table tops of cylinder block near afterbody.
Be compact structure, stressed more reasonable, the processing positioning and clamping table top near the stator installation base described in the present invention is to arrange by the inboard or the rear side of location and installation boss root.
Improvement main points of the present invention: 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.
Of the present invention improving one's methods 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, cylinder block of the present invention 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 present invention, 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 invention are further described: cylinder block of the present invention, 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 structure of the present invention, 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 present invention has the good stator attachment face of planeness provides reliable assurance for the position degree of the relative dimensions of following process, thereby improves the machining accuracy of each size of cylinder block and position degree.
