Description

A kind of Rotary Compressor pumping upper bracket

Technical field

The utility model belongs to Compressor Technology field, and in particular to a kind of Rotary Compressor pumping upper bracket.

Background technology

Compressor is a kind of machinery by gas compression lift gas pressure, by the generator of such as motor, turbine etc To its supply electric power, and the working fluid of such as air, refrigerant etc is compressed makees work, to improve working fluid pressure Mechanism, this compressor makes extensively from the various applications of the household electrical appliance of such as air-conditioner, refrigerator or the like to factory With according to the difference of its compress mode, reciprocating, swinging, scroll-type, spiral, centrifugal, axial-flow type etc. can be divided into.

In traditional Rotary Compressor, pumping is one important component.Pumping include cylinder body, upper bracket, Undersetting, silencer cover, bent axle and ring, axle and ring are rotated at a high speed under the drive of electric motor, and upper and lower bearing and cylinder body are formed Confined space in compressing refrigerant gas, compress the HTHP cold media gas for completing from cylinder body, upper bracket discharge opening, noise reduction Cover discharge compressor, so as to the effect for reaching refrigeration and heat.

However, six big critical pieces one of of the upper bracket as Rotary Compressor pumping, its effect mainly supports bent The shaft portion of axle, and form compression stroke with cylinder body, undersetting；Valve block and bluff piece are installed on the exhaust passage of pumping, and Valve block and bluff piece are riveted together by rivet with upper bracket.

Fig. 1 is the embryo material schematic diagram of existing Rotary Compressor pumping upper bracket；Fig. 2 is A-A generalized sections in Fig. 1； Fig. 3 is the finished product schematic diagram of existing Rotary Compressor pumping upper bracket；Fig. 4 is A-A generalized sections in Fig. 3.With reference to Fig. 1- 4, existing Rotary Compressor pumping upper bracket when finished product is processed, the valve block groove face 1b of upper bracket below annular groove face 2b, That is annular groove face 2b and valve block groove face 1b forms ring-shaped step, as shown in Figure 3-4；However, when embryo material is processed, annular groove face 2a With valve block groove face 1a at grade, as shown in Figure 1-2；So that this of existing Rotary Compressor pumping upper bracket Plant structure setting and there is following technical problem：

1) when the processing of roughing part is carried out, cutter need to downwards be processed by annular groove face 2a, produce Lathe quantity to cause knife greatly Tool service life is low；

2) the annular groove face 2b close with valve block groove face 1b can be made to produce burr when valve block groove face 1b is processed, need to increases artificial Carry out deburred, labor intensive；

3) when roughing part is processed, because annular groove face 2b and silencer cover mating surface produce 1~2mm steps, in finished parts When being ground processing, fixed sliding block is easily pressed at step, causes upper bracket to produce perpendicularity bad phenomenon, increases scene bad Rate and upper bracket scrappage.

Therefore, can be protected again while how when ensureing that upper bracket is processed, raising cutter life and reduction manpower expend The high yield rate for demonstrate,proving upper bracket turns into a problem demanding prompt solution.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided in a kind of Rotary Compressor pumping Bearing, can effectively solve that cutter life is low and labor intensive and yield rate technical problem not high when upper bracket is processed.

To achieve the above object, the utility model uses following technical proposals：

A kind of Rotary Compressor pumping upper bracket, including axle sleeve and positioned at axle sleeve one end it is integrally formed to excircle on Bearing floor, the floor sinks downwards towards prominent axle sleeve one end an oblique conic annular groove, the oblique conic annular groove from Middle that an annular boss is formed to prominent axle sleeve one end, the convex annular table top of the annular boss is valve block groove face, Sink to having valve block groove on the valve block groove face, valve bluff piece is fixed with by rivet in the valve block groove.

Preferably, the Rotary Compressor pumping upper bracket also includes being arranged at oblique conic annular groove multiple rings of a week Shape through hole and manhole, the circumference of the floor are evenly equipped with three welding hole at welding hole, and three and avoid annular through-hole and circle The periphery of through hole is set.

Preferably, one end that the axle sleeve is protruded is axially consistent circle ring.

Preferably, the inwall of the axle sleeve is provided with helical oil groove.

The Rotary Compressor pumping upper bracket that the utility model is provided, will be higher than valve block groove face in traditional upper bracket floor Annular groove face be changed to oblique conic annular groove face and make valve block groove face be higher than with oblique conic annular groove face, it has following beneficial effect Really：

1) when embryo material is processed, cutter only direct turning need to go out valve block groove on valve block groove face, and Lathe quantity is reduced, cutter Abrasion and life-span greatly increase；

2) because valve block groove face is higher than oblique conic annular groove face during attrition process, and hindered without the boss being higher by, fixed sliding block Can normally be pressed against on upper bracket valve block groove face, and then the bad phenomenon of upper bracket perpendicularity can be avoided to produce, and then scene is not Yield and scrappage are substantially reduced；

3) valve block groove face is higher than to be set with oblique conic annular groove face, and cutter will not touch oblique conic ring during processing valve block groove Shape groove face, therefore oblique conic annular groove face will not produce burr, and then reduce the personnel of field polish burr and reduce operation The work of personnel, and then improve production efficiency.

In addition, annular through-hole and manhole are avoided to be set at 3 welding holes, the firm of floor at 3 welding holes is strengthened Property, deformation of the upper bracket after the vertical compressor welding of group is reduced, reduce because compressor efficiency is low caused by upper bracket deformation Or the problems such as startability difference.

Furthermore, axle sleeve is changed to axially consistent circle ring by traditional circle convex platform formula structure, it is to avoid extra Processing, reduces Lathe quantity, and then improve the operating efficiency of on-site personnel.

Finally, the inwall in axle sleeve is provided with when helical oil groove may be such that axle sleeve coordinates with bent axle major axis and avoids or subtract Less wear, improves bent axle service life.
