Description

Technical Field

[0001] This invention relates to components of a ground-rail laser cutting machine, specifically to a ground-rail self-adjusting crossbeam mounting structure. Background Technology

[0002] Currently, the tracks on both sides of the ground-rail laser cutting machine are installed separately, making it difficult to guarantee the straightness and parallelism of the tracks on both sides. In order to achieve the design accuracy during installation and operation, the resistance of the upper crossbeam increases during operation, which reduces the acceleration and speed of the equipment. If high acceleration and high speed are forced, it will cause irreversible damage to the equipment, and the precision of the processed workpieces will be very poor.

[0003] Currently, the connection method of the guide rails on both sides of the crossbeam of the ground-rail laser cutting equipment is a rigid connection, which results in low acceleration and speed, and cannot fully utilize the performance of the equipment. In addition, some equipment is not strong enough and deforms after running for a period of time, which further degrades the performance of the equipment. Summary of the Invention
