Abstract

The invention discloses a hydraulic cylinder of a novel spring buffering device. The hydraulic cylinder of the novel spring buffering device comprises a hydraulic cylinder body and a buffering device,wherein the hydraulic cylinder body comprises a cylinder bottom, a cylinder barrel, a hollow piston rod, a cylinder cover, a first oil port, a fastening hexagonal nut, a piston, a second oil port anda guide sleeve; the buffering device comprises a buffering cylinder bottom, a buffering cylinder barrel, a buffering cylinder cover, a buffering piston and a buffering spring. According to the hydraulic cylinder, the impact energy generated by the movement of the hydraulic cylinder body can be partially or fully absorbed.

Description

technical field [0001] The invention relates to a hydraulic cylinder, in particular to a hydraulic cylinder of a novel spring buffer device. Background technique [0002] The hydraulic cylinder is an important linear actuator in the hydraulic transmission system, mainly including pistons, piston rods, cylinder barrels, cylinder heads and other components. When a hydraulic cylinder drives a part with a large mass to reciprocate quickly, the moving part has a lot of kinetic energy. Therefore, when the piston moves to the end of the hydraulic cylinder, it will collide with the cylinder head, resulting in impact and noise. This mechanical shock will not only cause damage to the hydraulic cylinder itself, but may also cause damage to other connected mechanical parts. [0003] In order to reduce or even completely absorb this harmful impact, the present invention has designed a hydraulic cylinder of a novel spring buffer device. When the piston moves to the end of the hydraulic...
