Abstract

The invention relates to a large hydraulic mechanism, in particular to a cross beam leveling device for a large hydraulic machine. The cross beam leveling device for the large hydraulic machine comprises a cross beam and four hydraulic leveling devices connected with the lower end face of the cross beam, wherein the four hydraulic leveling devices are arranged at four corners of the cross beam respectively; and the hydraulic leveling devices each comprise a plunger cylinder used for rough adjustment and a stepping hydraulic cylinder used for fine adjustment, and the bottom ends of the steppinghydraulic cylinders are fixedly connected with the top ends of the plunger cylinders. According to the cross beam leveling device for the large hydraulic machine, rough leveling and fine leveling ofthe cross beam of the hydraulic machine can be completed, so that leveling precision of the cross beam of the hydraulic machine is improved, and the application field of a hydraulic leveling technology is widened.

Description

technical field [0001] The invention relates to a large hydraulic mechanism, in particular to a horizontal beam leveling device for a large hydraulic machine. Background technique [0002] Large-scale overall isothermal die forgings require large-scale hydraulic machine processing, and large-scale hydraulic machines require multi-cylinder simultaneous coordinated output, and a mechanical structure with multi-cylinder synchronous and precise operation. However, due to the uneven material and asymmetric shape of the workpiece, the manufacturing of the hydraulic cylinder, the installation accuracy and other factors, the beam of the hydraulic machine is inclined, which affects the quality of the workpiece and reduces the life of the hydraulic machine. Therefore, it is necessary to carry out synchronous control on the movement of the horizontal beam of the hydraulic press. However, at present, the beams of hydraulic presses are mostly multi-cylinder parallel-driven hydraulic mac...
