The manufacture method of compressor rolling piston, it includes the following steps：(1), inner hollow cylinder, outer hollow cylinder, three concentric rings of size needed for preparing respectively；(2), one of concentric ring is fixed on to the medium position of inner hollow cylinder；(3), outer hollow cylinder is sleeved on the inner hollow cylinder in step 2 again, and by above-mentioned concentric ring external stability on outer hollow cylinder；(4), remaining two concentric ring is separately fixed on two ends of inner hollow cylinder and outer hollow cylinder again.Since concentric ring and interior outer hollow cylinder can be prepared on a large scale at the same time, and part specifications are few, and it is easy to prepare, and therefore, convenient, fast can manufacture compressor rolling piston by concentric ring and interior outer hollow cylinder, and production efficiency is high.
Description
Technical field
The present invention relates to the manufacture method of a kind of manufacture method of compressor part, particularly rolling piston.
Background technology
Rotary compressor for refrigerant, also known as rolling rotor compressor, it is rotated using piston carries out refrigerant gas
Compression, has been launched early in century last year, it is one of current most common compressor.
Rolling piston is the important part of rotary compressor for refrigerant set, it is arranged on the bias of the eccentric shaft of compressor and turns
On, when refrigeration, rolls along cylinder wall, and the cylindrical wall close contact with rolling-rotor, composition are dynamic under spring force for slide plate
Sealing, with rotary compressor using novel environment-friendly refrigerant, high efficiency and it is energy saving etc. become more diverse, to can be suitably used for height
Rolling piston under the rigor conditions such as load, high power, high temperature, high pressure proposes the requirement of higher.
For a long time, rolling piston outer ring is solid, therefore its weight is big.It is the rotation of driving rolling piston, it is necessary to flower
Take more energy.For this reason, there is hollow rolling piston, in theory, it appears that there are a variety of methods to prepare, but
There is higher intensity again since rolling piston needs to have preferable frictional behaviour, still can not be according to common processing methods
Obtain the qualified products for meeting performance requirement.
The content of the invention
The technical problems to be solved by the invention are to overcome the above-mentioned deficiency of the prior art and provide a kind of compressor rolling
The manufacture method of piston, is simple to manufacture rolling piston, cost is low and meets product requirement.
Technical solution is used by the present invention solves above-mentioned technical problem：
The manufacture method of compressor rolling piston, it includes the following steps：
(1), inner hollow cylinder, outer hollow cylinder, three concentric rings of size needed for preparing respectively；
(2), one of concentric ring is fixed on to the medium position of inner hollow cylinder；
(3), outer hollow cylinder is sleeved on the inner hollow cylinder in step 2 again, and by above-mentioned concentric ring external stability outside
On hollow cylinder；
(4), remaining two concentric ring is separately fixed on two ends of inner hollow cylinder and outer hollow cylinder again.
Preferably, the inner side of above-mentioned two concentric rings for being placed in two end of inner hollow cylinder and outer hollow cylinder cuts out one respectively
Inclined-plane, so reduces the weight of concentric ring on the premise of the support force of concentric ring is ensured.
Preferably, above three concentric ring is identical ring, can so be produced in enormous quantities.
Preferably, above-mentioned concentric ring is fixed by welding on inner hollow cylinder or outer hollow cylinder.
As stated above, so that it may produce the rotary compressor for refrigerant rolling piston of qualification.
A kind of manufacture method of compressor rolling piston is also provided, it includes the following steps：
(1), inner hollow cylinder, outer hollow cylinder, three concentric rings of size needed for preparing respectively；
(2), one of concentric ring is fixed on to the medium position of outer hollow cylinder；
(3), inner hollow cylinder is sleeved on the outer hollow cylinder in step 2 again, and by including above-mentioned concentric ring external stability
On hollow cylinder；
(4), remaining two concentric ring is separately fixed on two ends of inner hollow cylinder and outer hollow cylinder again.
Preferably, the inner side of above-mentioned two concentric rings for being placed in two end of inner hollow cylinder and outer hollow cylinder cuts out one respectively
Inclined-plane, so reduces the weight of concentric ring on the premise of the support force of concentric ring is ensured.
Preferably, above three concentric ring is identical ring, can so be produced in enormous quantities.
Preferably, above-mentioned concentric ring is fixed by welding on inner hollow cylinder or outer hollow cylinder.
Compared with prior art, the advantage of the invention is that：Since concentric ring and interior outer hollow cylinder can be large quantities of at the same time
Prepared by amount, and part specifications are few, and it is easy to prepare, and therefore, convenient, fast can be manufactured by concentric ring and interior outer hollow cylinder
Compressor rolling piston, and production efficiency is high.
