Abstract
The invention relates to a refrigeration compressor, the structure of which comprises an upper flange (4), a cylinder (2), a crankshaft (11), a rolling piston (7), a slide plate (8), a spring (9), a lower cylinder cover (5), an electric motor (3), and a housing. Bosses are circumferentially arranged on the upper flange (4), and the upper flange (4) is connected to an inner wall of the housing (1) through the bosses (10). The upper flange of the compressor is in welding connection with the housing through welding between the bosses and the housing. Heat generated due to high temperature, during welding, is directly conducted to the bosses, so that deformation stress generated from the welding heat is not delivered to a pump body, thereby preventing pump body deformation or even dead lock due to high temperature generated from welding fixation of the upper flange and the housing. Material consumption is reduced, and the weight of the compressor is reduced. Reliability of the pump body is increased, and the manufacture qualified rate of a whole refrigeration compressor is improved.
Description
Technical field
The present invention relates to a kind of heat pump and refrigeration system apparatus field, be specifically related to a kind of rolling piston refrigeration compressor and the pump housing.
Background technique
Traditional rolling piston refrigeration compressor is that the pump housing of circular spoke upper flange form assembling completely and casing are welded and fixed.Because upper flange circumference is an entirety, the whole upper flange size distortion of the temperatures involved produced during welding, thus cause the pump housing stuck, and the upper flange structure of circle not only increases the weight of compressor, also consumes more material.
Summary of the invention
The present invention is intended to provide a kind of refrigeration compressor, the high temperature produced when it can prevent upper flange and casing to be welded and fixed and the generation of the situation causing pump housing size distortion even stuck, and can reduce materials consumption, alleviates the weight of compressor.
Refrigeration compressor of the present invention comprises: upper flange, cylinder, bent axle, rolling piston, slide plate, spring, lower cylinder head, motor, casing, wherein upper flange and bent axle, cylinder, rolling piston, slide plate and lower cylinder head are assembled together the complete pump housing of composition one, slide plate one end and rolling piston offset, the other end is connected with spring, the other end of spring is against the inwall of the pump housing, gives by spring the elastic force that rolling piston one is reset to its home position;
The circumferencial direction of upper flange is provided with boss, and upper flange is fixed together by the inwall of described boss and casing.
Together with described upper flange to be welded and fixed with the inwall of casing by described boss.
The inwall of casing axially arranges guide slot, thus when assembling, boss can be assembled to the position of specifying exactly along guide slot.
The surface of contact of described boss and casing inner wall is circular arc.
The number of described boss is 3.
The size of 3 described boss is all identical.
3 described boss are uniformly distributed setting at the circumferencial direction of upper flange.
The shape of described 3 boss on the upper flange of described compressor is irregular shape.

Embodiment
Below with reference to the accompanying drawings the specific embodiment of the present invention is described in detail.
Fig. 1 represents the overall structure figure of refrigeration compressor of the prior art, and Fig. 2 represents the welded structure figure of the upper flange of refrigeration compressor of the prior art.
As depicted in figs. 1 and 2, refrigeration compressor comprises upper flange 4, cylinder 2, bent axle 11, rolling piston 7, slide plate 8, spring 9, lower cylinder head 5, motor 3, casing 1.
As depicted in figs. 1 and 2, upper flange 4 and bent axle 11, cylinder 2, rolling piston 7, slide plate 8 and lower cylinder head 5 are assembled together the complete pump housing of composition one, slide plate 8 one end and rolling piston offset, the other end is connected with spring 9, the other end of spring is against the inwall of the pump housing, gives by spring the elastic force that rolling piston 7 one is reset to its home position.
Further as shown in Figure 2, in the prior art, in order to upper flange 4 and casing 1 are assembled together, need the edge of upper flange 4 and casing 1 to weld together.Because upper flange is an entirety, the high temperature produced during welding may cause the distortion of whole upper flange 4.Particularly for light duty compressor, this distortion is larger on the impact of compressor overall performance, and compressor can be caused time serious stuck.In addition, the upper flange structure of unitary circular adds the weight of compressor, and particularly for light duty compressor, the large young pathbreaker of weight seems more important.
Fig. 3 represents the structural representation of the upper flange of refrigeration compressor of the present invention.
As shown in Figure 3, according to an embodiment of the invention, in order to overcome above-mentioned defect of the prior art, the circumferencial direction of upper flange 4 is provided with boss 10, compressor is when assembling, and upper flange 4 can be fixed together with the inwall of casing 1 by the described boss 10 arranged.
Above-mentioned mode of execution of the present invention makes upper flange 4 with casing and non-direct contact, but can pass through boss mediate contact, and therefore distortion directly or in large quantities can't conduct to upper flange 4, thus can prevent or alleviate the distortion of upper flange 4 preferably.
According to an embodiment of the invention, together with upper flange 4 can be welded and fixed with the inwall of casing 1 by the described boss 10 arranged.
Be understandable that, because welding part is the boss 10 of upper flange 4, therefore can alleviates and even prevent upper flange itself from deforming, and, even if cause boss 10 that some deformation occur in welding process, also can not impact upper flange 4.
According to an embodiment of the invention, assembling is aimed at more accurately in order to make boss 10, and workload when alleviating assembling, at the inwall of casing 1, axially guide slot can be set, thus when assembling, boss 10 can slide to the position of specifying exactly along guide slot, and can prevent upper flange from unnecessary rotation occurring.
According to an embodiment of the invention, described boss 10 is circular arc with the surface of contact of casing 1 inwall, due to the shape of casing inner surface inherently circular arc, therefore above-mentioned setting is carried out to boss 10 and can make between boss and the casing inner surface of circular arc, to obtain one and well mate and fix.
According to an embodiment of the invention, the number of described boss 10 is 3, because 3 fixing modes can bring a best rock-steady structure, and the number of boss 10 is set to 3 be also most economical, the most succinctly, fixed structure the most easily.
According to an embodiment of the invention, the size of described 3 boss 10 is identical, such design can convenient processing and carry out batch production.
According to an embodiment of the invention, 3 described boss 10 are uniformly distributed setting at the circumferencial direction of upper flange 4, by such be arranged so that 3 boss and casing are fixed time can be more stable, and the processing and manufacturing of being also more convenient for.
According to an embodiment of the invention, the shape of described 3 boss 10 on the upper flange 4 of described compressor is irregular shape, owing to considering that boss will be arranged on upper flange at inner peripheral surface on the one hand, the outer circumferential face of boss will be fixed with the inner peripheral surface of casing on the other hand, and likely also consider the layout of other parts, the design carried out required in actual processing and assembly process is considered in the setting therefore carrying out this kind.
Above-described embodiment not limits the invention, and those skilled in the art can design alternative embodiment when not departing from claims scope.In the claims, any reference symbol between bracket should be configured to limitations on claims.Word " comprises " not to be got rid of existence and does not arrange element in the claims or step.
