AI Technical Summary
Existing hydraulic cylinder actuators require auxiliary devices such as connecting rods when arc motion is needed, resulting in complex structures, large space occupation, and high failure rates.
Design an arc reciprocating motion cylinder. Through the support of the piston and the sliding sleeve, the piston is made to circulate and reciprocate in the cylinder by means of air pressure or hydraulic pressure difference, which drives the piston rod to achieve arc motion. The structure is simple and occupies little space.
It achieves efficient execution of arc motion, simplifies the structure, reduces space occupation, and lowers the failure rate.

Abstract
Claims
1. An arcuate reciprocating motion cylinder comprising a piston rod (1), a piston (2), a sliding sleeve (3), a sealing ring (4), a coupling head (5), a rear end cover (6), a front end cover (7), a cylinder barrel (8), characterized in that: The cylinder (8), piston rod (1), and piston (2) are determined according to actual needs, and the piston reciprocates in the cylinder under the action of air pressure or hydraulic pressure.
2. The curvilinear reciprocating cylinder of claim 1, wherein: Pneumatic or hydraulic pressure is applied to both sides of the piston (2). Through the support of the piston (2) and the sliding sleeve (3) and the sealing effect of the sealing ring (4), a pressure difference is formed on both sides of the piston, causing the piston (2) to move and drive the piston rod (1) to move. The piston rod (1) is connected to other devices through the connector (5). Driven by the piston, it moves together with the other connected devices. Through the guiding effect of the cylinder (8), the piston (2) and the other driven devices move in an arc.
3. An arcuate reciprocating cylinder according to claim 1 or 2, characterized in that: The input method of air pressure or hydraulic pressure on both sides of the piston (2) is adjustable, including alternating input of pressure on both sides of the piston to make the piston (2) move back and forth, and keeping a fixed pressure on one side of the piston (2) so that the reaction force transmitted to the piston (2) through the piston rod (1) makes elastic movement.
