Important function in machine, designing and manufacturing aspect, there has also been very big change and raisings, are just able to satisfy society height in this way
It is required that discharge standard.
The sound construction of one-piece piston, but maintenance cost is high, and seperated piston needs to assemble.Usually it is arranged in piston
There is pin shaft and the fixation hole of pin shaft is installed, this brings difficulty to the assembling of Split piston, needs to improve.
Utility model content
The purpose of this utility model is to provide a kind of built-up pistons of pin shaft limit, carry out Split piston using piston
Limit promotes assembling convenience.
For this purpose, the utility model uses following technical scheme:
A kind of built-up piston of pin shaft limit, comprising: top cover, first piston housing, second piston housing and pin shaft, it is described
Top cover is arranged in the top of first piston housing, is set on the lower section of first piston housing outside the second piston, and described the
One piston jacket inner wall bottom is provided with the insertion set for extending to second piston outer casing inner wall bottom, the second piston housing and
The bottom of insertion set is correspondingly arranged on symmetrical two lead-in grooves upwardly extended, is circumferentially provided with cunning at the top of the lead-in groove
Slot, the pin shaft is horizontally installed in insertion set and both ends extend respectively in the sliding slot of second piston outer casing inner wall, and described the
The bolt being connected with end part of pin shaft is provided on two piston jackets.
Wherein, the top cover is integrated aluminium alloy structure with first piston housing.
Wherein, the outer wall of the insertion set fits with second piston outer casing inner wall.
Wherein, the outer wall of the second piston housing is symmetrically arranged with stepped hole corresponding with sliding slot, the bolt setting
In stepped hole.
Wherein, indent is provided with first gas ring slot, the second piston housing at the top of the outer wall of the second piston housing
Outer wall on indent be provided with the second gas ring slot below first gas ring slot.
Wherein, indent is provided with the oil ring groove below second gas ring slot on the outer wall of the second piston housing.
The utility model has the beneficial effects that a kind of built-up piston of pin shaft limit, when assembling, insertion set insertion second piston
In housing, pin shaft both ends enter sliding slot by lead-in groove, are fixed after rotating by a certain angle using bolt, easy to operate, benefit
The limit that insertion set and second piston housing is strengthened with pin shaft, avoids the use of Spring Card, and structural stability is high.
Detailed description of the invention
