The diameter of section of column III is arranged different.
Further, integral structure is made in the rotary table I and cylinder I；The cylinder II, rotary table II, cylinder III and company
It connects ring and integral structure is made.
Further, the rotary table I and replacement part are all made of cold-rolled steel and are made.
Further, the roughness of the rotary table I and replacement part outer surface is set as 1.6 microns.
Further, the depth of the annular groove is less than the height of cylinder II, the height of connection ring and the depth of annular groove
It is identical.
Further, a kind of piston ring assembling clamp further includes containing box, and the inside of the containing box is equipped with groove, described
The shape of groove is correspondingly arranged with rotary table I and replacement part respectively.
(3) beneficial effect
A kind of piston ring assembling clamp provided by the invention, is first fastened on piston crown for the lower end of cylinder III, then will
Piston ring is nested on rotary table I, from top to bottom sliding plunger ring, until piston ring sticks into the compression of piston, it is entire to install
Situations such as process rapid and convenient avoids piston ring and generates plastic deformation, and caused opened gap becomes larger, combustion chamber gas leakage hair
It is raw；Replacement part can be replaced in real time according to the size of piston cross-section, enhance the practicability of tooling, replacement process is screw thread
Connection or disassembly, assembling quickly, save the time.
