Abstract

The utility model discloses a compressor bottom seat structure, which is composed of a bottom cover and a bottom angle, the bottom cover and the bottom angle are formed integrally, wherein the triangle-shaped bottom angle is positioned on the lower side, the circular bottom cover is formed above the bottom angle integrally and the circle center of the bottom cover and the gravity center of the bottom angle are on the same point. Fixing holes are formed on the three corners of the bottom angle positioned on the lower side respectively, the bottom cover positioned on the upper side is a concave-shaped circular cap structure, and both side surfaces on the periphery of the concave shape are inclined waveform structures. The utility model has the advantages that the bottom cover and the bottom angle of the compressor are formed by pressing in one step integrally, the welding procedure is reduced, the production cost is reduced, the requirements to the intensity of the welding procedure and the deformation of the bottom cover and the bottom angle caused by the welding are avoided and the generation of compressor noises is reduced.

Description

The compressor bottom cap structure

Technical field

The present invention relates to a kind of.It is simple particularly to relate to a kind of assembling procedure, and cost is low, avoids the compressor deformation of bottom, guarantees the compressor bottom cap structure of weld strength.

Background technique

Usually, rotary compressor be with running shaft that motor combines on off-centre be combined with press part and roll ring, roll ring and in circular cylinder, carry out linear motion, suck refrigerant and compress the back and discharge.

Fig. 1 is the compressor inner structure schematic representation; Fig. 2 is the structural representation that the compressor bottom cap of prior art combines with the base angle; Fig. 3 is the side view of the compressor bottom cap of prior art.

The rotary compressor structure as shown in Figure 1, it is to be made of following structure: be provided with suction port 109a and output tube 118, and the top of inside that is filled with the housing of certain gauging is equipped with the stator 103 and the rotor 102 of motor; And be pressed into running shaft 105 at the center of its rotor 102; Below running shaft 105, be provided with the press part that absorbs compression refrigerant.

Press part is made of following structure: the circular cylinder 109 that is fixed on the inner peripheral surface of housing and connects with suction pipe; The upper bearing 110 and the lower bearing 111 of combining closely and in the bi-side of cylinder 109, being through with running shaft 105; With running shaft 105 is the center, and that carries out in cylinder 109 simultaneously that off-centre rotatablely moves rolls ring 107, and is provided with the compression volume 108 that forms compression refrigerant gas when rolling ring 107 rotations with upper bearing 110, lower bearing 111.

The as above housing of the existing closed rotary compressor of Gou Chenging is that shell 11, bottom 21 3 parts by loam cake 31, tubbiness constitute.As Fig. 2, shown in Figure 3, wherein, the structure of bottom 21 is the convexity structure.The side that dome outwards protrudes forms the outside of compressor housing bottom, and with compressor base angle 2 by being welded together.Compressor base angle 2 structures triangular in shape respectively are formed with a fixed hole 5 on leg-of-mutton 3 angles, the effect of fixed hole 5 is to be used for compressor is fixed on the object that uses it as air-conditioning, refrigerator etc.On three limits of compressor base angle, also be provided with the noise that is produced when vibration damping groove 4 is used to reduce vibration of compressor.

But this compressor housing and triangle base angle are the package assemblies that connects together by welding, have following deficiency: 1. in the process of welding, bottom 21 produces distortion, and base angle 2 is easy deformation also, and distortion has caused the vibration of compressor, produces noise; 2. welding bottom 21 and base angle 2 time, be difficult to guarantee weld strength, therefore, pneumatics the phenomenon of falling will occur when detecting; 3. complex procedures, the cost height.

Summary of the invention

Technical problem to be solved by this invention is, provides a kind of assembling procedure simple, and cost is low, avoids the compressor deformation of bottom, guarantees the compressor bottom cap structure of weld strength.

The technical solution adopted in the present invention is: a kind of compressor base frame structure, be to constitute by bottom and base angle, described bottom and base angle are formed as one, wherein, below leg-of-mutton base angle is positioned at, circular bottom be integrally formed in the base angle above, the center of circle of bottom and the center of gravity at base angle are on same point.Be positioned on three angles at following base angle and be formed with fixed hole respectively, being positioned at top bottom is the dome structure of spill, and two Jie sides of the periphery of spill all are the ramp waveform structure.

Compressor base frame structure of the present invention, bottom and base angle one piece punching press formation with compressor have reduced welding process, reduced cost of production, avoided the requirement of welding process, and, reduced the generation of compressor noise because of the bottom that caused of welding and the distortion at base angle to intensity.

Embodiment

Below, in conjunction with the accompanying drawings and specific embodiment, describe compressor base frame structure of the present invention in detail.

Fig. 4 is the structural representation of compressor base frame of the present invention; Fig. 5 is the A-A sectional view of Fig. 4.

As shown in Figure 1, the compressor housing of prior art is to be made of the shell of loam cake, tubbiness, bottom three parts, and bottom constitutes with triangle base angle secure bond.After adopting base of the present invention, compressor housing is to be made of loam cake, shell, bottom three parts, wherein base such as Fig. 4, structure shown in Figure 5.

As Fig. 4, shown in Figure 5, the compressor base frame structure is to be made of bottom 21 and base angle 12, and described bottom 22 and base angle 12 are formed as one, that is, bottom 22 and base angle 12 are that the one piece punching press forms.The center of gravity at the center of circle of described bottom 22 and base angle 12 is on same point.Wherein, below leg-of-mutton base angle 12 is positioned at, circular bottom 22 be integrally formed in base angle 12 above, be positioned on three angles at following base angle 12 and be formed with fixed hole 5 respectively, the effect of fixed hole 5 is to be used for compressor is fixed on the object that uses it as air-conditioning, refrigerator etc.Be positioned at top bottom 22 and be the dome structure of spill, two sides of the periphery 15 of spill are the ramp waveform structure.

The bottom 22 of spill dome structure of the present invention and the shell secure bond of compressor tubbiness, constitute the housing of compressor, because being the one piece punching press, base forms, so, reduced welding process, reduced cost of production, avoided having reduced the generation of compressor noise because of the bottom that caused of welding and the distortion at base angle.
