Abstract
The invention discloses an aluminum-alloy straight-stoke piston type pneumatic actuator. The aluminum-alloy straight-stoke piston type pneumatic actuator comprises a straight-barrel-shaped cylinder body, a bracket which is in sealing connection with the cylinder body and a top cover which is in sealing connection with the top end of the cylinder body, wherein a piston which moves along the cylinder body in a reciprocating mode is arranged in the cylinder body; the two side walls of the piston are in sliding fit with the inner wall of the cylinder body; the center of the piston is fixedly connected with a piston rod; the tail end of the piston rod penetrates out of the lower end of the cylinder body and extends into the bracket; a guide sleeve is arranged on the center of the piston; the guide sleeve is arranged on the piston rod in a sleeving mode; the top end of the piston rod is connected with a nut in a rotary mode for enabling the guide sleeve to be in compression connection on the upper surface of the piston; the center of the upper surface of the piston is provided with a ring of bumps; peripheries of the bumps are provided with a ring of clamping slots; large springs are clamped in the clamping slots, and small springs are arranged on the bumps in the sleeving mode to form a dual-spring structure; top ends of large and small springs are provided with limiting collision blocks; large and small springs are pressed between the limiting collision blocks and the piston; the top ends of the limiting collision blocks are connected with limiting screws; upper ends of the limiting screws extend out of a top cover; and the upper ends of the limiting screws are connected with nuts in a rotary mode for being regulated and fixed. The aluminum-alloy straight-stoke piston type pneumatic actuator is high in air source pressure bearing capacity, great in thrust force, high in travelling speed, firm and durable.
