Specific embodiment
As shown in figure 1, the piston rod device that the present invention is used for refrigeration compressor includes piston 1, ball-and-socket 2, gonnecting rod body 6 and
Connecting rod set 5.Gonnecting rod body 6 comprises bulb 3 and connecting rod 4.Its assembling process is as follows：
The first step：Will be integrally welded at joint portion 31 in advance for bulb 3 and connecting rod 4 or bulb 3 become with connecting rod 4 overall processing
Gonnecting rod body 6；
Second step：Gonnecting rod body 6 one end with bulb 3 is loaded in ball-and-socket 2, forms a complete ball-and-socket joint；
3rd step：The ball-and-socket joint that step 2 is completed loads piston 1 positioned internal, then using welding method by ball-and-socket 2
Link into an integrated entity with inside piston 1；
4th step：Load in crankcase cylinder by overall for piston 1, connecting rod 4 other end is fixedly connected with connecting rod set 5, and connection can be adopted
With welding, riveting, pin connection or other method（Powder metallurgy part preferably adopts pin connection）.
Please refer to shown in Fig. 2 and Fig. 3, the making material system sheet metal of piston 1, through extruding or other cold working side
Method is made.The top 11 of piston 1 has bigger wall thickness than piston side 12, helps avoid piston 1 during work
Deformation.The inside of piston 1 is provided with resigning bulb 3 and moves and oil storage space 14（Can be circular arc or other shapes）.Piston 1 interior
Portion is provided with the projection 13 of symmetrical two or more, and the thickness difference of raised 13 formation closes as asphalt channel lubrication ball-and-socket
