Abstract

The present invention discloses one kind of long stroke oil cylinder driving mechanism, which includes one movable worktable comprising one vertical ribbed plate and one top plate, one driving oil cylinder for driving the movable worktable, one rigid hinge shaft and one flexible hinge shaft for supporting the driving oil cylinder, one protecting cover outside the driving oil cylinder, and one buffering spring. The long stroke oil cylinder driving mechanism with both rigid support and flexible support on the driving oil cylinder has simple structure and convenient installation and use.

Description

technical field [0001] The invention belongs to a hydraulic machine, in particular to an oil cylinder drive mechanism capable of ensuring good rigidity of a drive cylinder of a movable workbench of a large hydraulic machine, a certain rotation angle, and a long stroke with reliable support. Background technique [0002] At present, the composition of the existing hydraulic press generally includes an upper beam and a lower beam; pillars at four end angles respectively arranged between the upper beam and the lower beam; 1. A slider that can move up and down along the guide plates set on the pillars on both sides; a mobile workbench is set on the lower beam. Usually, the drive of the mobile worktable is driven by a hydraulic motor or an electric motor or a small oil cylinder, and it is also driven by a chain drive. [0003] But at present along with the development of industry, large-scale hydraulic presses have appeared, such as the appearance of large-scale hydraulic presse...
