The shape of groove is correspondingly arranged with round platform I and replacing part respectively.
(3) beneficial effect
A kind of piston ring assembling clamp provided by the invention, is first fastened on piston crown by the lower end of cylinder III, then will
Piston ring is nested on round platform I, from top to bottom sliding plunger ring, until piston ring is sticked into the compression of piston, whole installation
Process rapid and convenient, avoid piston ring and produce plastic deformation, caused opened gap becomes situations such as big, combustion chamber gas leakage and sent out
It is raw；Change part to be changed in real time according to the size of piston cross-section, strengthen the practicality of frock, Renewal process is screw thread
Connection or dismounting, assembling is quick, saves the time.
