Portion is equipped with buffering adjusting screw, and the cylinder barrel side is equipped with left air inlet pipe, and it is solid that guide post passes through removable rear end cap connection
Determine rear end cap, stroke adjustment screw is installed in the middle part of the fixed rear end cap, nut is installed in the stroke adjustment screw.
A kind of method of the adjusting stroke for the cylinder that can precisely adjust stroke,
The first step moves the adjustment that rear end cap passes through stroke adjustment screw and nut, can precisely be parked in designated position,
Set cylinder stroke；
Second step, the guide post and fixed rear end cap for being mounted on removable rear end cap are slidably matched, and move rear end cap only
It is axially moveable；
Third step, compressed air enter from left air inlet pipe, push piston to move to the right, the air of piston right passes through the right side
Air inlet pipe discharge；
4th step, when buffer piston guide section touches cushion seal circle, after the air of piston right changes by moving
Throttling road below end cap is just discharged from right air inlet pipe.Under the control of buffering adjusting screw, piston traveling speed starts to slow down；
5th step, piston are stopped by removable rear end cap, are finally stopped movement.
Preferably, the sealing ring is rubber seal.
Preferably, the buffering adjusting screw side is equipped with blocking.
The characteristics of this stroke adjustable cylinder:
1. easy to use, function does not change, identical as the cylinder of standard specification.
2. occupying little space, the more aobvious advantage in long stroke.
3. retain the pooling feature of cylinder terminal, low noise, without impact, left alone without help it is steady.
4. without technology difficulty, series standard product can be become.
