Abstract
The utility model discloses oil cylinder ball pivot bindiny mechanism, comprise attachment post, pressing plate, base and oil cylinder body, there is attachment post oil cylinder body one end, and the end of attachment post is ball pivot, and the centre of sphere of ball pivot is on the axis of attachment post.Adopt the oil cylinder of ball pivot bindiny mechanism, when there is assembly error, maintenance oil cylinder axis is parallel with active force or overlap, and the mechanism of fixed oil cylinder can be made can not to produce the phenomenons such as loosening, tired or fracture.Improve the safety and stability using cylinder apparatus.
Description
Technical field
The utility model relates to the bindiny mechanism of oil cylinder, particularly oil cylinder ball pivot bindiny mechanism.
Background technique
Oil cylinder is a kind of energy conversion device, and it converts other energy modes the active force of straight line motion to.Desirable working environment is that oil cylinder axis is parallel with active force or overlap.Often because assembly error causes that oil cylinder axis and active force are not parallel not to be overlapped in actual using process.Loosen if adopt in process service time that is rigidly connected can cause connecting, fatigue is bindiny mechanism's fracture equivalent risk even.
Summary of the invention
The technical problems to be solved in the utility model is: loosen for solving to adopt in rigidly connected oil cylinder process service time can cause connecting, fatigue is bindiny mechanism's fracture equivalent risk even.
The technical solution adopted in the utility model is: oil cylinder ball pivot bindiny mechanism, comprises attachment post, pressing plate, base and oil cylinder body, and there is attachment post described oil cylinder body one end, and the end of attachment post is ball pivot, and the centre of sphere of ball pivot is on the axis of attachment post.
Described base has the concave surface matched with ball pivot, the concave surface degree of depth is less than the radius of the ball pivot centre of sphere.
Described pressing plate is made up of the plate of 2 semicircles piled, and there is the concave surface matched with ball pivot at the center of pressing plate.
Ball pivot is pressed in the concave surface matched with ball pivot on base by described pressing plate.
Advantage of the present utility model and useful effect are: the oil cylinder adopting ball pivot bindiny mechanism, and when there is assembly error, maintenance oil cylinder axis is parallel with active force or overlap, and the mechanism of fixed oil cylinder can be made can not to produce the phenomenons such as loosening, tired or fracture.Improve the safety and stability using cylinder apparatus.
Accompanying drawing explanation
Fig. 1 is with the oil cylinder schematic diagram of oil cylinder ball pivot bindiny mechanism;
Fig. 2 ball pivot bindiny mechanism schematic diagram;
Fig. 3 pressure plate structure schematic diagram.
1. attachment post 2. pressing plate 3. base 4. oil cylinder body 5. ball pivot.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: oil cylinder ball pivot bindiny mechanism, comprise attachment post 1, pressing plate 2, base 3 oil cylinder body 4 and ball pivot.There is attachment post 1 described oil cylinder body 4 one end, and the end of attachment post is ball pivot 5, and the centre of sphere of ball pivot 5 is on the axis of attachment post 1.
Base 3 has the concave surface matched with ball pivot 5, the concave surface degree of depth is less than the radius of the ball pivot centre of sphere.
Pressing plate 2 is made up of the plate of 2 semicircles piled, and there is the concave surface matched with ball pivot 5 at the center of pressing plate 2.
Ball pivot 5 is pressed in the concave surface matched with ball pivot 5 on the base 3 by pressing plate 2.
Adopting the oil cylinder of ball pivot bindiny mechanism, when there is assembly error, the mechanism of fixed oil cylinder can be made can not to produce the phenomenons such as loosening, tired or fracture.Improve the safety and stability using cylinder apparatus.
