Problems solved by technology

[0002] As we all know, most of the trunnion brackets of the current cylinder adopt the embracing fixing method, that is, the two brackets are symmetrically hugged and fixed on both sides of the cylinder body. Push-pull force and extrusion sag and loosen. Under the impact of the reciprocating motion of the cylinder piston, the trunnion bracket will slide axially on the cylinder block, and the axial sliding of the trunnion bracket on the cylinder block will cause the overall position of the cylinder to shift. , so that the position of the cylinder is deviated when it moves 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 destroy the overall equipment, causing major accidents.
At the same time, the radial coaxiality of the cylinder after the trunnion bracket of the current cylinder is fixed is difficult to guarantee and difficult to adjust, which affects the accuracy of the product

Embodiment Construction

[0021] in such as Figure 4 Figure 6 In the shown embodiment 1, there are two trunnion supports, which are arranged symmetrically on both sides of the cylinder body 1. The shape is an arch structure. It is an arc-shaped structure, and the central angle corresponding to the arc surface of the cylinder contained in the arc-shaped structure is 110 degrees. There is an arc-shaped gap 31 in the middle of the arc-shaped structure, and a platform 6 is arranged between the trunnions 2 and the arc-shaped gap 31. (See figure 1 ). Both sides of the arch surface 3 are provided with fixing holes 4, the fixing holes 4 are screw holes, the outside of the fixing holes 4 is an arch extension structure 7, and the bottom surface of the extension structure 7 is provided with a pillar hole 8, two on each side, and the pillar hole 8 is the pin hole (see figure 2 ). Prop 9 is housed on the prop hole 8, respectively two on both sides. Cylinder body 1 is provided with lug 12, and lug 12 is fou...

Abstract

The invention discloses a trunnion mounting of an air cylinder. The trunnion mounting of the air cylinder is arranged at the two sides of the cylinder body symmetrically and is an arch structure. The top of the trunnion mounting is provided with trunnions under which arch faces are arranged. The two sides of the arch faces are provided with fixing holes. The trunnion mounting is connected with a cylinder body by fixed screws. 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 bracket, in particular to a trunnion bracket of a cylinder. Background technique [0002] As we all know, most of the trunnion brackets of the current cylinder adopt the embracing fixing method, that is, the two brackets are symmetrically hugged and fixed on both sides of the cylinder body. The push-pull force and the extrusion will loosen after the depression. Under the impact of the reciprocating motion of the cylinder piston, the trunnion bracket will slide axially on the cylinder block, and the axial sliding of the trunnion bracket on the cylinder block will cause the overall position of the cylinder to shift. , so that the position of the cylinder is deviated when it is 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 destroy the overall equipment, causing major accidents. At the sa...
