Air cylinder

Abstract

An air cylinder, the air cylinder comprising a cylinder body (1), a main cavity (2), a piston (3) and a piston rod (4), wherein air inlets and air outlets (5) are respectively formed in two ends of the cylinder body (1), an anti-collision structure (6) is arranged on the air cylinder and comprises a buffer rod (61), the buffer rod (61) is arranged on the piston (3), an accommodation hole corresponding to the buffer rod (61) is formed in the cylinder body (1), and a first sealing ring (63) for sealing a clearance between the buffer rod (61) and the accommodation hole (62) is arranged at the accommodation hole (62). The anti-collision structure has a flexible buffer function without generating hard impact, so that the air cylinder is small in vibration and high in stability.

Description

technical field [0001] The invention belongs to the field of pneumatic transmission, and more specifically relates to a cylinder. Background technique [0002] In the prior art, the cylinder uses high-pressure gas or high-pressure liquid as the power source to perform reciprocating motion to realize the transmission function, such as figure 1 As shown, the cylinder generally includes a cylinder body 1, a main cavity body 2, a piston 3 and a piston rod 4, and the two ends of the cylinder body 1 are also provided with inlet and outlet ports 5, and the piston will hit the front and rear covers on the cylinder body during the working process of the cylinder. , The mechanical damage to the cylinder itself is greater during the piston impact stop process, which greatly increases wear and deformation, resulting in shortened life; in addition, the impact will cause vibration. When the cylinder is used to transport items, it may have adverse effects on vibration-sensitive items. The...
