The air pressure in the sixth chamber 332 is higher than the air pressure in the fifth chamber 331, and the baffle disc 33 faces one end of the fifth chamber 331, so that the large piston 32 is driven to extend.
The air pressure in the fourth chamber 221 is higher than the air pressure in the third chamber 221, the second choke disc 223 moves away from the link rod 221, and the first choke disc 222 pushes the assist lever 23 to the bottom in the direction of the second choke disc 223.
The hole position on the assist rod 23 changes and returns to the initial state. Therefore, the function of automatically reversing the inward extension and outward extension of the large piston is realized.
Compared with the prior art, the stroke-adjustable automatic reversing cylinder provided by the invention limits the motion track of the large piston 32 through the stroke adjusting assembly 40, so that the stroke of the large piston 32 is adjusted. The stroke-adjustable automatic reversing cylinder realizes the inlet and the discharge of high-pressure gas through the mutual alternate motion of the small piston 12, the connecting rod shaft 22 and the assistant rod 23, so that the large piston 32 performs reciprocating motion. The cylinder only needs one air supply module, so that resources are saved, and the requirement of industrial production is met.
