Abstract

The invention discloses a two-edge gear and rack simultaneous drive device for a laser cutting machine. The device slides in a lathe bed groove through a control block, drives a gear installed on a reducer to move, and further adjusts the size of a gap between the gear and a rack. The device solves the problems that a lathe bed is twisted due to accumulated errors and internal stress damages a transmission system.

Description

technical field [0001] The invention relates to a synchronous driving device, in particular to a double-sided rack and pinion synchronous driving device for a large-format laser cutting machine. Background technique [0002] The airborne laser cutting machine basically adopts a synchronous double drive structure, usually two drive devices are installed on the same bed, and the two are completely rigidly connected. However, because the racks on both sides cannot be completely consistent in the process of processing and installation, and sometimes even have large deviations, the two driving devices are installed on the same bed, so the bed can only adapt to the drive on both sides with its own elastic deformation. inconsistent. Due to the extremely high rigidity of the bed, even a very small deformation will generate huge stress, and these stresses must be transmitted between the bed and the base through the transmission chain, which may damage the precise transmission system...
