Cylinder structure

Abstract

The invention discloses an air cylinder structure. The air cylinder consists of a cylinder body, end covers arranged at the two ends of the cylinder body and a trunnion mounting arranged on the cylinder body. The outer wall of the cylinder body is provided with lugs along the axial direction of the cylinder body. Mounting holes are arranged in the lugs. The lugs provided with the trunnion mounting are provided with nicks and the trunnion mounting is mounted in the nicks. Fixed screws drill through the lugs to be connected with the trunnion mounting. The invention effectively solves the problems that the trunnion mounting of the existing air cylinder sliding along the axial direction on the air cylinder causes the shift of the air cylinder and position deviation when the air cylinder moves forward or backward. The problems can cause the invalidation of the automation equipment and the scrapping of the products, even endangering personal security or damaging the whole equipment and causing a heavy accident. The invention has simple structure, convenient operation, low production cost and is worthy of promotion.

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...

[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 shift, causing the cylinder to deviate in position when moving forward and backward. In the light case, the automation equipment will fail to work and the product will be scrapped. In the severe case, it will endanger the safety of personnel or damage the overall equipment, resulting in major accidents.

At the same time, it is difficult to ensure the radial coaxiality of the cylinder after the trunnion bracket of the current cylinder is fixed, and it is also difficult to adjust, which affects the accuracy of the product
