Oil cylinder buffer device and oil cylinder

Abstract

The invention discloses a buffer device for an oil cylinder, which comprises a plugging assembly, a triggering assembly and an adjusting assembly arranged in the oil port of the oil cylinder. The oil is throttled by the trigger assembly and the adjustment assembly, and then returns to the trigger assembly, and finally flows through the trigger assembly and is discharged through the oil port. Through the above method, the cushioning device and the cylinder of the present invention realize the adjustment of the cushioning performance without replacing the cushioning parts, eliminating the cumbersome steps of repeated disassembly and assembly of the cylinder, and the size of the control opening can be adjusted, making it easier Get the best cushioning and performance.

Description

technical field [0001] The invention relates to the field of oil cylinders, in particular to a buffer device for an oil cylinder and the oil cylinder. Background technique [0002] With the development of industrial technology, mechanical equipment is everywhere, and many equipment need to use oil cylinders to complete some related actions. Oil cylinders have simple structure, large output force, can be used as high-power power components, high work efficiency, stable and reliable performance , Easy to use and maintain and other excellent features are widely used in various mechanical fields. However, due to the relatively large output force of the oil cylinder, there is a certain speed during the extension and retraction of the piston rod. This speed should be reduced to zero when the piston rod reaches the most extended state or the most retracted state. If the cylinder bottom or end cover If there is no buffer device at the position, the speed of the piston rod will drop...

AI Technical Summary

Problems solved by technology

[0004] The existing technology needs to replace the buffer parts to achieve different buffer effects; every time the buffer parts are replaced, the entire oil cylinder must be disassembled, replaced and reassembled, which is labor-intensive, time-consuming, and labor-intensive; the process formed on the buffer parts The flow area can only be determined by changing the angle of the flat wire of the buffer sleeve, the length of the end, the opening of the buffer ring, etc. through artificial estimation. It consumes many parts but can only determine a relative buffer performance.
