Abstract

The invention discloses a cylinder structure. The cylinder is composed of a cylinder body, end covers arranged at both ends of the cylinder body and a trunnion bracket arranged on the cylinder body. Lugs are arranged on the outer wall of the cylinder body along the axial direction of the cylinder body. A mounting hole is arranged inside, a notch is provided at the position where the trunnion bracket is installed on the lug, the trunnion bracket is fitted into the notch, and the fixing screw passes through the lug and is connected with the trunnion bracket. It effectively solves the problem that the trunnion bracket in the current cylinder slides axially on the cylinder, causing the overall position of the cylinder to deviate, causing the position of the cylinder to deviate when it moves forward and backward, causing the automation equipment to fail to work, the product to be scrapped, and heavy to occur. or endanger the safety of personnel or damage the overall equipment, resulting in major accidents. The invention has the advantages of simple structure, convenient use and low production cost, and is worthy of popularization and application.

Description

technical field

[0001] The invention relates to a cylinder, in particular to a cylinder structure. Background technique

[0002] As we all know, the cylinder body of most cylinders currently adopts round tubes. When fixing the trunnion brackets, most of these cylinders adopt the embracing fixing method, that is, the two brackets are symmetrically hugged and fixed on both sides of the cylinder. The cylinder of this structure is used. After a long time, due to the loosening of the fixing bolts, or the loosening of the cohesive contact surface after being pushed and pulled or squeezed and dented, under the impact of the reciprocating motion of the cylinder piston, the trunnion bracket will slide axially on the cylinder, and the trunnion bracket will slide on the cylinder. Sliding in the upper axis will cause the overall position of the cylinder to deviate, causing the cylinder to deviate in position when moving forward and backward. In the light case, it will cause the automati...
