Abstract

The invention discloses a single-action swing clamp cylinder low in rotation resistance. The single-action swing clamp cylinder comprises a cylinder body, a piston and reset springs, wherein the piston and the reset springs are installed in the cylinder body. A seal ring is arranged between the piston and the cylinder body, a pressure cavity is formed in the cylinder body, and a liquid / gas inlet hole formed in the cylinder body is communicated with the pressure cavity. A swing pressing plate rod is arranged in the cylinder body and penetrates through the piston, one end of the swing pressing plate rod is connected with a pressing plate, the other end of the swing pressing plate rod extends into the cylinder body so as to be fixed to one end of a swing guide rod, and a swing guide structure is arranged between the swing guide rod and a swing guide sleeve. The single-action swing clamp cylinder can achieve the swing clamping function even when the pressure is lower than 0.1 MPa, so that the application range is wider.

Description

technical field [0001] The invention relates to a hydraulic or pneumatic corner cylinder, in particular to a single-action corner cylinder with low rotational resistance. Background technique [0002] The single-acting corner cylinder in the prior art has a large resistance of the sealing ring during the rotation process, so the corner function can only be realized under the condition of high pressure. Some structures cannot realize the corner function. Its rotating part of present corner cylinder all has sealing ring, and the frictional resistance of sealing ring and cylinder block is bigger, and its resistance is bigger when there is pressure. Existing corner cylinders are limited in application range (especially when the pressure is lower than 0.1MPa). Contents of the invention [0003] In view of the defects of the existing single-acting corner cylinder, the object of the present invention is to provide a low-rotation-resistance single-acting corner cylinder that can...
