Abstract
The present invention discloses the working method of a kind of fixed scroll, relate to Machining Technology field, fixed scroll has scroll portion and the bottom in its scroll portion that distributes multiple projections circumferentially install legs, the protruding outer rim diameter installing leg is the first diameter, the protruding interior edge diameter installing leg is Second bobbin diameter, and it comprises the following steps: A, clamped by the cylindrical in scroll portion with three-jaw folder dish; B, rough turn: to adopt the straight line tool path pattern with fixed scroll axes normal that bottom surface is carried out turnery processing; C, essence car: adopt oblique line tool path pattern that bottom surface is carried out turnery processing, make bottom surface form the first diameter place height, the inner conical surface that Second bobbin diameter place is low. Compared to prior art, the present invention can improve the working accuracy of its bottom surface planeness.
Description
Technical field
The present invention relates to Machining Technology field, in particular for the method processed by fixed scroll.
Background technology
Dynamic and static scroll is the important moving parts of screw compressor, casts by aluminium alloy; Fixed scroll covered by installing the machine that is bolted to that bottom it, multiple projection installs leg; Its bottom surface a kind of is had to be provided with four protruding fixed scrolls installing leg, it is 0.012 millimeter that the flatness tolerance of this bottom surface requires, but after completing the turnery processing of bottom surface, carry out detection plane degree all between 0.012��0.018, reach or beyond the requirement of the drawing opposite degree tolerance upper limit; When dynamic and static scroll can be caused to engage running as being contained on screw compressor by fixed scroll overproof for bottom surface flatness tolerance and orbiter cooperation, the upper surface stopping property of the type line of its cavity volume bottom surface and orbiter is poor, the phenomenon revealed even occurs; Lathe and cutter having been adjusted respectively, its result is still undesirable; Its reason there is unrelieved stress owing to installing leg inside in multiple projection, and after the fixed scroll completing to process deposits for some time, its bottom surface produces caused by distortion under unrelieved stress effect; Therefore, how improving the processing quality of fixed scroll bottom surface, producing the high fixed scroll of bottom surface planeness precision is screw compressor industry practitioner problem urgently to be resolved hurrily.
Summary of the invention
Technical problem to be solved by this invention is to provide the working method of a kind of fixed scroll improving its bottom surface planeness working accuracy.
The technical scheme that technical solution problem of the present invention adopts is: the working method of this kind of fixed scroll, fixed scroll has scroll portion and the bottom surface in its scroll portion that distributes multiple projections circumferentially install legs, the outer rim diameter that described projection installs leg is the first diameter, the interior edge diameter that described projection installs leg is Second bobbin diameter
Comprise the following steps:
A, with three-jaw folder dish, the cylindrical in scroll portion is clamped;
B, rough turn: to adopt the straight line tool path pattern with described fixed scroll axes normal that the bottom surface in described scroll portion is carried out turnery processing;
C, essence car: adopt oblique line tool path pattern that the bottom surface in described scroll portion is carried out turnery processing, make the bottom surface in described scroll portion form described first diameter place height, the inner conical surface that described Second bobbin diameter place is low.
In the working method technical scheme of above-mentioned fixed scroll, technical scheme can also be more specifically: Second bobbin diameter described in described first diameter ratio is high 0.02 millimeter.
Owing to have employed technique scheme, the present invention is compared with prior art, the useful effect having is: due to when the bottom surface in scroll portion carries out essence car, by utilizing anti-deformation principle, outer rim first diameter place height is processed in the bottom surface being provided with multiple projection installation leg, the inner conical surface that interior edge Second bobbin diameter place is low, after for some time placed by part, distortion under predeformation and unrelieved stress effect is cancelled out each other, adopted the bottom surface of the fixed scroll of this method processing by detection, within the scope of equal 0.06 millimeter��0.01 millimeter of flatness tolerance, meet design requirements.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fixed scroll of the embodiment of the present invention.
Fig. 2 is the sectional view at the M-M place of Fig. 1.
Fig. 3 is the schematic diagram of the oblique line tool path pattern of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
It is fixed scroll as depicted in figs. 1 and 2, the fixed scroll of the present embodiment has scroll portion and the bottom surface in its scroll portion that distributes four projections circumferentially install legs, the protruding outer rim diameter installing leg is the first diameter phi D1, first diameter phi D1 is �� 79 millimeters, the protruding interior edge diameter installing leg is Second bobbin diameter �� D2, the first diameter phi D2 is �� 49 millimeters.
The working method of fixed scroll comprises the following steps:
A, with three-jaw folder dish, the cylindrical in scroll portion is clamped;
B, rough turn: to adopt the straight line tool path pattern with fixed scroll axes normal that the bottom surface in scroll portion is carried out turnery processing;
C, essence car: adopt oblique line tool path pattern that the bottom surface in scroll portion is carried out turnery processing, the bottom surface in scroll portion is made to form the first diameter phi 79 place height, the inner conical surface that Second bobbin diameter �� 49 place is low, the first diameter phi 79 place is higher than Second bobbin diameter �� 49 place 0.02 millimeter, as shown in Figure 3.
