Exchange device for elevated worktable of laser cutting machine

Abstract

The invention belongs to the field of laser machining equipment and particularly relates to an exchange device for an elevated worktable of a laser cutting machine. The exchange device comprises a fixed guide block and a slideway assembly, wherein one end of the slideway assembly is fixedly connected to the fixed guide block, a first chain wheel is arranged on one side of the fixed guide block and is movably connected to the slideway assembly, one end of the slideway assembly is movably connected to a second chain wheel, chains are connected to the first chain wheel and the second chain wheel, and two ends of the chains are fixedly connected to a lower traction guide ball and an upper traction guide ball, respectively. According to the exchange device for the elevated worktable of the laser cutting machine provided by the invention, the worktable which rises and falls is guided by the fixed guide block and the traction guide balls simultaneously; the worktable dragged by the traction guide balls displaces left and right to alternately arrive the working position, so that the worktable rises and falls. The moving distance is precisely controlled by a servo motor and a coder, and meanwhile, accelerating and decelerating regions are reasonably arranged at the same time. The exchange device is simple in structure and short in exchange time, and the work efficiency of the equipment is greatly improved.

Description

technical field [0001] The invention belongs to the field of laser processing equipment, and in particular relates to a lifting workbench exchanging device for a laser cutting machine. Background technique [0002] At present, most of the double-layer lifting and exchange workbenches are composed of guide blocks and pin cylinders. When dragging, the proximity switch senses the position and stops when it is in place. When the pin cylinder needs to be retracted, the proximity switch will decelerate and stop at last, and the deceleration time and deceleration distance cannot be adjusted well, so there are disadvantages such as complex structure, cumbersome movements, unsmooth deceleration during exchange, and long exchange time. For this reason, We propose a laser cutting machine lifting table exchange device. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a laser cutting ...
