Specific embodiment
In conjunction with referring to shown in Fig. 1 to Fig. 3, a kind of cylinder block of embodiment according to the present invention, comprising:
Cylinder block ontology 1；
Stator core 2, stator core 2 and cylinder block ontology 1 are integrally formed.
It is low with 2 assembly precision of stator core that cylinder block of the invention solves cylinder block, restricts stator core 2, motor turns
The problem of gap width design of son 3, cylinder block main body 1 and stator core 2 are integrally formed, number of parts, cylinder block are reduced
Machining tool is not needed with mounting surface, only exists time processing error, using the motor of this kind of cylinder block, installation accuracy is higher,
Stator, rotor clearance value can be designed smaller, and not have to worry that stator and rotor can not assemble or occur rotor and sweep thorax
Problem further increases the efficiency of compressor so as to improve electric efficiency.
The rapid metallic prototyping technique that the present invention uses can be metal injection molded, metal liquid molding.
Casting forming is as a kind of a kind of essence for forcing for molten metal to be pressed into complex-shaped metal mold using high pressure
Close casting has high production efficiency, and process is simple, and Casting tolerance is higher ranked, and surface roughness is good, and mechanical strength is big, can
To save a large amount of machining operation and equipment, the advantages that saving material, so having become one in China's foundry industry
A important component.
Preferably, cylinder block ontology 1 and stator core 2 are made of the molding technique of integral die-cast.
The cylinder block ontology 1 and stator core 2 of the present embodiment, integral die-cast production efficiency is higher, the tolerance etc. of die casting
Grade is higher, without further finishing.Cylinder block main body 1 and 2 integral die-cast of stator core, the gap of identical stator, rotor
In the case where design value, after the cylinder block and rotor 3 of integral die-cast assemble, the gap between stator, rotor is more uniform,
The noise generated when stator, relative rotation of rotor is smaller, and overall noise is smaller when motor operation.
In the present embodiment, cylinder block ontology 1 is equipped with crankshaft installed hole 4, and cylinder block ontology 1 includes several stabilizer blades 5, if
Circumferentially along crankshaft installed hole 4, stator core 2 is arranged on several stabilizer blades 5 Heavenly Stems and Earthly Branches foot 5.
Preferably, cylinder block ontology 1 include four stabilizer blades 5, four stabilizer blades 5 along crankshaft installed hole 4 circumferentially, stator iron
Core 2 is arranged on four stabilizer blades 5.
Cylinder block in this implementation stator core 2 is arranged on stabilizer blade 5, it is ensured that preferable stability, cylinder block
There is overall structure enough intensity can effectively reduce cylinder block weight using 5 structure of stabilizer blade relative to the cylinder block of monoblock type
Amount, saves the material of cylinder.
Cylinder block ontology 1 and stator core 2 are integrally formed, and are not required to process mating surface in 5 end face of stabilizer blade, are not also needed to process
Threaded hole is installed, 5 intensity of stabilizer blade increases.Meanwhile the diameter of stabilizer blade 5 can also be reduced, and material usage amount be saved, thus cylinder block
Total quality reduces.
The embodiment of the present invention is integrally formed using cylinder block ontology 1 and stator core 2, is connected without using screw, accordingly
The use that can save screw and screw gasket, save material usage amount, thus cylinder block total quality reduce.
2 top of stator core is reserved with the positioning column 7 for installing support spring 6, after stator core 2 winds line
It is fitted into lower case 8.
In the prior art, motor stator and cylinder block are fixedly mounted on three on cylinder block by screw and screw gasket
On a installation foot.Screw exposes a part in motor stator upper end, can be used for positioning support spring 6 just.
Stator core 2 in the present embodiment is installed without using screw, when die casting, 2 top of stator core is reserved and spiral shell
Follow closely similar positioning column 7.
In order to improve the overall performance of cylinder block of the invention, cylinder block main body 1, stabilizer blade 5 using can die casting magnetic conduction material
Material production, and guarantee that permeability magnetic material hardness is greater than HB180.Using the cylinder block of the permeability magnetic material die casting of hardness HB180, both met
Work piece production cost, and can guarantee that workpiece has excellent performance.
On the other hand, such as Fig. 4, the motor stator of the prior art are needed due to needing to install by screw in motor stator
On along axial direction open up multiple mounting holes 13, it is necessary to reserve enough processing spaces on motor stator corner for mounting hole 13, this
Kind structure necessarily leads to the increase of motor stator outside diameter and wall thickness, causes the increase of motor stator overall weight and material.
The stator core plane structure chart of Fig. 5 the present embodiment, cylinder block ontology 1 and 2 integral die-cast of stator core, eliminate
Screw connection, does not need to open up mounting hole 13 on stator core 2, does not need to reserve enough processing on stator core 2 yet
Space, in the case where same inner diameter, the motor stator of the stator core 2 of the present embodiment compared to the prior art, outside diameter
What can be done is smaller, and overall weight and supplies consumption are less.
Meanwhile reducing the hole machined technique of mounting hole 13, processing cost is saved, stator core 2 does not need after forming
The interior microscopic performance of further mechanical process, workpiece is not damaged.
Cylinder block provided in an embodiment of the present invention reduces due to stator verticality, cylindricity equidimension tolerances, and peace
Filling column flatness tolerance influences, and reduces stator and cylinder block and installs matching step, due to tooling, parts machining tolerances,
The problem of design of motor stator, rotor clearance value is to electric efficiency reduction must be increased.
According to the another aspect of the application, the present embodiment also discloses a kind of compressor, including above-mentioned motor, is mounted on
The crankshaft 9 in crankshaft installed hole 4 is stated, and the connecting rod 10, piston pin 11, piston 12, the valve group (figure that are mounted in above-mentioned cylinder block
In do not mark) and 2 top of stator core support spring 6 and the lower case 8 outside stator core 2.Above-mentioned compressor is main
Component is installed on cylinder block, constitutes compressor main body, and rotor 3 and 2 gap width of stator core are designed as 0.3-
0.5mm, motor effect is higher, and compressor efficiency is more preferable, and gap turns with more evenly, and compressor noise is smaller.Thus cylinder block
Shape has significant beneficial effect to the stator of motor, rotor clearance design in compressor, and compressor performance, volume and weight are equal
Available biggish improvement.
From foregoing description, it can be seen that cylinder block main body 1 and stator core 2 are integrally formed by cylinder block of the invention,
Reduce cylinder block main body 1, the manufacture of stator core 2 and build-up tolerance, using this kind of cylinder block motor can by stator, turn
Sub- gap width designs smaller, to improve electric efficiency, further increases the efficiency of compressor.
Cylinder block main body 1 and stator core 2 are integrally formed, and reduce the use of the materials such as rigging screw, gasket, fixed simultaneously
Sub- iron core 2 does not need reserving installation hole 13, and 2 outer circle of stator core can reduce, and consumption of materials is reduced, and equipment is effectively reduced
Weight and production cost.
