Abstract

The invention discloses a guide device of a movable workbench of a hydraulic machine. The guide device mainly adopts the technical scheme that square notch grooves are formed in the bottom of the movable workbench and at the edge opening positions in the front, back, left and right directions of the movable workbench; piston cylinders are arranged inside the movable workbench in the inward direction of the square notch grooves; bearing supports are arranged at the notch parts of the square notch grooves in a wedged mode; bearings are arranged on the bearing supports; a total adjusting plunger cylinder is further arranged at the bottom of the movable workbench; a working cavity of the total adjusting plunger cylinder communicates with inner cavities of other hydraulic cylinders; and a plunger of the total adjusting plunger cylinder is adjusted so that the bearings can be adjusted to stretch out, and the contact intensity between the bearings and a guide rail can be adjusted. The guiding device has the advantages of being good in guiding precision, flexible in guiding and easy to maintain and adjust.

Description

technical field [0001] The invention belongs to the technical field of hydraulic presses, in particular to a guide device for a movable workbench of a hydraulic press. Background technique [0002] For large CNC hydraulic machines, the workbench generally has a moving function. The function of the mobile workbench is to transport materials and molds to a specific work location. Therefore, not only high precision of movement is required, but also flexible movement is required. At the same time , During the working process of the hydraulic machine, the guide device will inevitably change, therefore, it also needs to have the characteristics of convenient adjustment and maintenance. [0003] Although the existing hydraulic press mobile workbench also realizes the above-mentioned functions to a certain extent, there are more or less defects of poor guiding precision, inflexible guiding and inconvenient maintenance and adjustment of the guiding device.
