Specific embodiment
As shown in figure 1, the piston rod device that this utility model is used for refrigeration compressor includes piston 1, ball-and-socket 2, connecting rod
Body 6 and connecting rod set 5.Gonnecting rod body 6 includes bulb 3 and connecting rod 4.Its assembling process is as follows：
The first step：By bulb 3 and connecting rod 4 it is integrally welded at joint portion 31 in advance or by bulb 3 and connecting rod 4 it is overall plus
Work is into gonnecting rod body 6；
Second step：By gonnecting rod body 6, the one end with bulb 3 loads in ball-and-socket 2, forms a complete ball-and-socket joint；
3rd step：Ball-and-socket joint that step 2 is completed loads the positioned internal of piston 1, then using the method for welding by ball
Nest 2 links into an integrated entity with the inner side of piston 1；
4th step：By in the overall loading crankcase cylinder of piston 1, the other end of connecting rod 4 is fixedly connected with connecting rod set 5, connects
