一种异形气缸

Profiled air cylinder

Abstract

一种异形气缸,设置有气缸筒、与所述气缸筒连接的气缸端盖、设置于气缸筒内的活塞、与活塞相连接的活塞杆以及装配于活塞杆的弹簧,气缸筒的内腔设置为长圆形,活塞设置为长圆形,活塞与所述气缸筒相配合,长圆形的过中心的长轴L为35mm,长圆形的过中心的短轴D为28mm。气缸端盖与气缸筒之间设置有长圆形密封垫,活塞内设有轴承,活塞设置有缓冲垫。本发明的异形气缸通过将气缸筒、活塞的形状设置为长圆形,将有效面积增大,从而实现了在不改变轴间距32mm的情况下能够增大该异形气缸的推力。
The invention provides a profiled air cylinder which is provided with an air cylinder barrel, an air cylinder end cover connected with the air cylinder barrel, a piston arranged in the air cylinder barrel, a piston rod connected with the piston and a spring arranged on the piston rod, wherein the shape of the inner cavity of the air cylinder barrel is set as a long circle; the shape of the piston is set as a long circle; the piston is matched with the air cylinder barrel; a long-circular long shaft L passing the center is 35mm; a long-circular short shaft D passing the center is 28mm; a long-circular sealing gasket is arranged between the air cylinder end cover and the air cylinder barrel; a bearing is arranged in the piston; and the piston is provided with a cushion pad. In the invention, since the shapes of the air cylinder barrel and the piston of the profiled air cylinder are respectively set as the long circle, the effective area is increased, and thereby, the thrust of the profiled air cylinder can be increased without changing the distance 32mm between the shafts.
