Hydraulic lifting system based on four-cylinder and multi-cylinder synchronization and control method

Abstract

The invention relates to the field of laser cutting machining, in particular to a hydraulic lifting system based on four-cylinder and multi-cylinder synchronization and a control method. The system comprises two workbenches arranged in parallel, first rotating shaft assemblies and guide rail bases, wherein a front thrust oil cylinder device and a rear tension oil cylinder device are arranged at the two ends of each workbench, the first rotating shaft assemblies are connected with the front thrust oil cylinder devices and the rear tension oil cylinder devices, the first rotating shaft assemblies are connected through middle connecting rod devices and side edge connecting rod devices, and the guide rail bases are rotationally connected with the first rotating shaft assemblies. According to the system, the lifting stability and synchronism of the guide rail bases are ensured, and meanwhile, the problems of low efficiency, fast temperature rise, complex oil path and high cost of a hydraulic system of the lifting workbench of a laser cutting machine are solved.

Description

technical field [0001] The invention relates to the field of laser cutting processing, in particular to a four-cylinder and multi-cylinder synchronous hydraulic lifting system and control method. Background technique [0002] With the popularization of the application of laser cutting technology in recent years, people have put forward higher requirements for the processing efficiency of laser cutting machines. At present, most laser cutting machines use a double-layer exchangeable lifting workbench. When one layer of the double-layer workbench is processed in the processing area, the loading and unloading work can be completed on the other workbench. Two-layer work The use of platform exchange can reduce the waiting time for loading and unloading, and greatly improve the working efficiency of the equipment. [0003] The general lifting table is driven by hydraulic pressure, and the four corners of the lifting table are driven by hydraulic cylinders to realize the up and do...
