Abstract
The present invention provides a vane inlaid integral piston and a production method thereof. The vane inlaid integral piston mainly comprises a vane and a piston which adopt an interference inlaid structure, namely that one side of the piston is provided with a through groove with a narrow opening and wide inside, the shape of the tail part of the vane is matched with the through groove, and the vane and the piston are in an interference fit. The finish machining technique of the present invention comprises that firstly finish machining the top circle of the piston and the two lateral surfaces of the vane, and then integrally finish machining and milling the two end surfaces of the piston and the inner hole of the piston after interference embedding the vane into the piston. Because the present invention adopts the structure of the inlaid fit of the piston and the vane, the process manufacturability of the integral piston is improved greatly, manufacturing cost and defective index are reduced effectively, and the present invention provides conditions for selecting different materials and processing modes of the vane and the piston.
Description
Technical field
The present invention relates to be applicable to the swing-rotor type compressor of air-conditioner, refrigerator and refrigerator, refer to the improvement and the manufacture method thereof of the piston structure in the compressor especially.
Background technology
Existing swing-rotor type compressor mainly is made of parts such as cylinder 7, integral piston, slide block 12, eccentric shaft 8, motors 2, and wherein integral piston is by blade and piston is integrated processes (referring to Fig. 1, Fig. 2).Motor 2 drives integral piston along the swing of cylinder 7 inwalls by eccentric shaft 8, finishes the working cycles of gas suction-compression-discharge.Upper cylinder cover 3, cylinder 7, integral piston, slide block 12, following cylinder cap 5 form swept volumes, and blade 4 is divided into low pressure (suction) chamber and high pressure (compression) chamber by the reciprocating and swing in the cylinder 7 that is supported in of slide block 12 with the cylinder internal volume.Slide block 12 is a semicylinder, swings in the cylinder slider bore.Because blade 4 fuses with piston 6, causes all difficult processing of cylindrical and blade 4 both sides of piston 6, there are the non-constant of integral processing, percent defective height, shortcoming that processing cost is high.
The Japanese kokai publication hei 5-202874 patent gazette that name is called " rotary compressor " also discloses a kind of integral piston, its technical characterictic is: this integral piston comprises blade and piston, one end of blade is inserted in the groove that piston one side offers, the two is fixed by adhesive and/or pin.But adopt the viscosity mixture to fix, easily aging, be difficult to bear the abominable working environment that has temperature difference and pressure differential and periodicity dynamic loading, its reliability is difficult to guarantee; Pin is fixing establishes pin more then because the thickness of blade itself has only 3-4mm in blade if adopt, and its diameter is littler, so its intensity, processing, assembling all can have difficulties, and reliability also has problem.
Summary of the invention
Problem in view of the said structure existence, the objective of the invention is to design a kind of integral piston with embedded blades, adopt special young interior big fit structure, blade is embedded in piston, make blade and the piston both can separate machined, also can guarantee the reliability that it is worked in the adverse circumstances that have temperature difference pressure differential and periodicity dynamic loading, can fully satisfy totally-enclosed, the middle working method of keeping in repair of nothing of compressor.Because blade can separate with piston, so the selection of blade and piston is more flexible, also can improve the processing technology of blade and piston, improves the quality of products.
A kind of integral piston with embedded blades of the present invention, mainly comprise blade and piston, have a groove in piston one side, the shape of blade tail shape and described groove is complementary, and be inlaid in the groove of described piston, it is characterized in that described groove is big in young, and adopt interference fit between the groove on described blade afterbody and the piston.
The fine-processing technique of integral piston with embedded blades of the present invention is: first machining piston cylindrical and blade two sides, treat that the blade interference embeds whole again fine finishining grinding side face of piston ring and piston inner hole behind the piston.
Because it is big in groove of the present invention is young, and adopt interference fit between the groove on described blade afterbody and the piston, therefore blade combines with piston firmly, reliable operation, the possibility that exists blade from piston, to deviate from anything but, can not occur blade play in groove yet, can bear the abominable working environment that has temperature difference and pressure differential and periodicity dynamic loading, thereby can fully satisfy totally-enclosed, the middle working method of keeping in repair of nothing of compressor.Because blade and piston are splits, so the selection of blade and piston is more flexible, also can improve the processing technology of blade and piston, improves the quality of products.

The specific embodiment
Now the invention will be further described in conjunction with several embodiment and accompanying drawing thereof.
A kind of integral piston with embedded blades of the present invention, mainly comprise blade 4 and piston 6, have a groove 61 in piston 6 one sides, the shape of blade 4 tail shapes and described groove 61 is complementary, and be inlaid in the described groove 61, big in described groove 61 is young, and adopt interference fit between the groove 61 on described blade afterbody and the piston.
Integral piston with embedded blades of the present invention is mainly used in swing-rotor type compressor as shown in Figure 1.By Fig. 1, motor 2 drives eccentric shafts 8 and rotates, and is with piston 6 because of eccentric shaft 8 is outer, thus piston 6 with eccentric shaft 8 swings, and it is reciprocating and swing in cylinder 7 to drive blade 4; Upper cylinder cover 3, cylinder 7, piston 6 form swept volumes with blade 4, following cylinder cap 5.As seen from Figure 2, piston 6 is divided into low pressure (air-breathing) chamber 13 and high pressure (compression) chamber 14 with blade with the cylinder internal volume, and slide block 12a, 12b are two semicylinders, as the fulcrum of piston 6, swings with blade 4 in the slider bore of cylinder 7.
