Description

Technical Field

[0001] This utility model belongs to the field of fixing device technology, specifically relating to a fixing device for a laser cutting machine. Background Technology

[0002] The main function of the fixing device on a laser cutting machine is to stably fix the workpiece on the machine's worktable, preventing processing errors caused by workpiece movement or shaking during the cutting process. This fixing device ensures that the laser cutting machine can precisely cut along a predetermined trajectory, thereby improving processing efficiency and product quality.

[0003] Traditional fixing devices typically only allow for the fixation and movement of the square tube. When different sides of the square tube need to be cut, the cutting angle is often adjusted by rotating the laser cutting machine itself to process other sides. However, the rotation of the laser cutting machine takes a considerable amount of time to complete the angle adjustment, which significantly delays the entire cutting process, resulting in low cutting efficiency. This long waiting time not only increases the production cycle but also reduces equipment utilization, thereby increasing production costs.

[0004] Therefore, in order to solve the above problems, it is necessary to design a fixing device for laser cutting machines. Utility Model Content
