Description

Technical Field

[0001] The utility model belongs to the technical field of laser welding machines, and particularly relates to a ground rail leveling mechanism for a laser cutting machine. Background Technique

[0002] A laser cutting machine emits laser from a laser, which is focused into a laser beam with a high power density through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the melted or vaporized metal. In order to improve the cutting efficiency, existing laser cutting machines mostly adopt a ground rail assembly to convey the workpieces to be processed and the processed plates. In order to improve the cutting accuracy, it is necessary to level the ground rail assembly.

[0003] After retrieval, a patent with the application number 201921172477.2 discloses a ground rail leveling system for a gantry laser cutting machine.

However, in actual use, it is necessary to install the pressing block, the pressing block support and the adjustment bolts separately, and the overall operation is more troublesome, time-consuming and laborious, and the use flexibility is poor.
