Description
Technical field
The present invention relates to the assembly method of compressor, particularly relate to the pump housing of compressor and the connecting method of housing.
Background technique
Compressor is the important composition parts that air conditioner, refrigerator etc. utilize the household electric appliance of cooling cycle system work.In general, compressor utilizes its parts that move under driven by motor (rolling piston or reciprocating piston etc.) to change mechanical energy into the pressure energy, realization is to the compression of compressor pump cylinder inner refrigerant, and refrigerant compressed is discharged compressor enters cooling cycle system and circulate.
Compressor commonly used mainly contains Reciprocting piston compressor, rotary compressor etc.Rolling piston compressor is modal rotary compressor, has characteristics such as volume is little, simple in structure, running is steady, noise is low, especially can adapt to variable parameter operation, so it is widely used on the air conditioner.
Fig. 1 shows the basic structure of the rolling piston compressor of using on a kind of air conditioner.As shown in Figure 1, compressor is a vertical structure, and cylindrical shell 1 is by loam cake 2 and lower cover 9 sealings.
The pump housing of compressor and motor are arranged in the cylindrical shell 1, and the pump housing is arranged on the bottom in the housing, and motor is arranged on the top in the housing.Bent axle 4 runs through the pump housing and motor, and motor drives the compressor pump running by bent axle 4.
The pump housing of compressor comprises main bearing 6, lower bearing 8 and cylinder 7.Main bearing 6 and lower bearing 8 are fixed on the both sides up and down of cylinder 7 by bolt 10, make the cavity that is formed with cylinder in the cylinder 7.In the cylinder cavity piston is set, piston sleeve turns in the off-centre of inserting cylinder 7 inside crankshafts 4 one ends, and the rotation of bent axle 4 drives piston and rolls along cylinder wall surface in cylinder 7, realizes entering the compression and the exhaust process of cylinder cavity inner refrigerant.Bent axle 4 rotates under driven by motor.
Motor is made up of stator 3 and rotor 5, and stator 3 and rotor 5 are made of the iron core that the folded collection of silicon steel core sheet forms respectively.Rotor 5 is cylindric, directly is pressed on the bent axle 4 and inserts in the cylinder cavity of stator iron core, has air gap to be separated by between rotor 5 and the stator 3.Embed the winding of enameled cable coiled on the stator 3, staor winding outside source current by the time produce magnetic field.Rotor 5 with the magnetic field interaction of stator 3, produces electromagnetic torque and rotation in stator 3 when having electric current to pass through.Rotor 5 drives bent axle 4 and rotates, and then the rolling of drive piston makes compressor operation.
In the compressor assembling, its pump housing need be fixed on the housing of compressor, and will stand the vibrations that compressor operation produces.Rolling piston compressor shown in Figure 1 by three spot welding connections with compressor pump coupling on compressor housing, promptly utilize some plug welding 11 in three welding holes that on compressor housing, are provided with the main bearing 6 of compressor pump and compressor housing 1 connection.
But there is the problem of welding hole poor air-tightness in the compressor pump coupling method that utilizes three spot welding connections of above-mentioned prior art.Owing to weld the uneven existence that produces thermal stress and welding slag of being heated, influence the tightness of welding hole, can make the oil leak in the enclosing housing easily.Particularly, the rotation of motor, the rolling of piston and cylinder cavity inner high voltage refrigeration agent spray the vibrations that brought, and more can reduce the tightness of the compressor housing that has welding hole.
Summary of the invention
At the compressor pump coupling method existing problems of utilizing three spot welding connections of above-mentioned prior art, the present invention adopts the method for punching press housing to make compressor pump and compressor housing fixed connection.
Compressor pump coupling method involved in the present invention comprises main bearing fluting and two steps of punching press housing.
Main bearing fluting: before the compressor assembling, process four stamped groove on main bearing and ring surface that housing contact, the inner chamber of stamped groove is the tetrahedron shape, and a tetrahedral gore is parallel with the end face of main bearing;
Punching press housing: when compressor assembles, on the hull outside position corresponding, utilize drift punching press housing from outside to inside, the part that is stamped of housing is caved in the stamped groove of main bearing into the main bearing stamped groove.
The drift of punching press housing be shaped as the tetrahedron that removes a triangular point, related tetrahedron is identical with the tetrahedron shape that the stamped groove inner chamber presents, the end face that removes the triangular point is a sphere, this sphere is as the stamping surface of punching press housing.
Compressor pump coupling method involved in the present invention utilizes drift punching press housing, the part that is stamped by housing caves in the stamped groove of main bearing into, make compressor pump and the compressor housing fixed connection that does not have welding hole, increase the tightness of compressor housing, stopped the generation of compressor lubrication oil leakage.Simultaneously, compare, have higher assembling work efficiency with three spot welding connections of prior art.
