Abstract
The utility model relates to a vane-inlaid integral piston, which essentially comprises a vane and a piston. The vane and the piston adopt an interference inlaid structure, a communicated groove has a small mouth and a big inner size and is arranged on one side of the piston, the shape of the tail on the vane is matched with the communicated groove, and the vane and the piston adopt interference matching. With adopting the interference inlaid structure between the vane and the piston, the utility model has the advantages of greatly improving the manufacturing processes performance of the integral piston, effectively reducing manufacturing cost and the rejection rate and providing a condition for choosing different materials and processing methods for the vane and the piston.
Description
Technical field: the utility model relates to the swing-rotor type compressor that is applicable to air conditioner, refrigerator and refrigerating machine, refers to the improvement of the piston structure in the compressor especially.
Background technique:
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 processes (referring to Fig. 1, Fig. 2) by blade and piston one.Motor drives integral piston along the swing of cylinder 7 inwalls by eccentric shaft 8, finishes the work cycle 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 moves reciprocatingly in the cylinder 7 by being supported in of slide block 12 and swings, and the cylinder internal volume is divided into low pressure (air-breathing) chamber and high pressure (compression) chamber.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 bi-side of piston 6, there are the non-constant of integral processing, reject rate height, shortcoming that processing cost is high.
Summary of the invention:
In view of the existing problem of said structure, the purpose of this utility model is a kind of integral piston with embedded blades of design, inserted cooperating structure by blade and piston, make blade and the piston can separate machined, and select different materials for use, thus improve piston and processing of leaves manufacturability, make processing cost to reach to reduce, reduce reject rate, select the purpose of the material of piston, blade flexibly for use.
A kind of integral piston with embedded blades of the present utility model, mainly comprise blade and piston, it is characterized in that described blade and piston adopt the interference embedded structure, promptly piston one side have young in big groove, the shape of blade afterbody and described groove are complementary, and adopt interference fit between described blade and the piston.
Because the utility model adopts piston and embedded blades cooperating structure, earlier after difference finishing pistons cylindrical and the blade side, assemble by interference fit again, whole more at last fine finishing both ends of the surface and piston inner hole, thereby improved the technology capability of integral piston greatly, effectively reduce and make processing cost and reject rate, and select different materials and processing mode for use for blade and piston condition is provided.

Embodiment:
Now the utility model is described in further detail in conjunction with several embodiments and accompanying drawing thereof.
A kind of integral piston with embedded blades of the present utility model, mainly comprise blade 4 and piston 6, it is characterized in that described blade 4 and piston 6 adopt the interference embedded structure, promptly have the big groove of young tripe 61 in piston 6 one sides, and the shape of blade 4 afterbodys and described groove 61 are complementary, and adopt interference fit between blade 4 and piston 6.
Integral piston with embedded blades of the present utility model is mainly used in the swing-rotor type compressor as Fig. 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 drive blade 4 moves reciprocatingly in cylinder 7 and swings; 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 4 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.
Embodiment 1:
Have a T shape groove 61 in piston 6 one sides, the T-slot on the shape of the afterbody of blade 4 and the piston 6 is complementary, and adopts interference fit at matching part, as shown in Figure 2.
Embodiment 2:
At the over-surplus fit structure of piston 6, as shown in Figure 3 with the matching part employing dove-tail form groove of blade 4.
Embodiment 3:
The matching part of piston 6 and blade 4 adopts the over-surplus fit structure of great circle hole slot, as shown in Figure 4.
Embodiment 4:
The matching part of piston 6 and blade 4 adopts the over-surplus fit structure of roundlet hole slot, as shown in Figure 5.
