[0014] Compared with the prior art, the beneficial effect of the utility model is that the 3D laser machine positioning platform is provided with:

[0015] 1. Center positioning structure. When the workpiece needs to be processed, the workpiece is first placed between the clamping plates at both ends. Then the clamping rod is manually pulled to separate the tail end of the clamping rod from the clamping slot inside the rotating disk. After separation, the counter-threaded rod is rotated by the rotating disk.

[0017] 2. Chip removal structure. The waste chips generated by this structure will fall to the upper end of the laser bracket through the hollow squares on the inner side of the platform plate. When these waste chips need to be cleaned, the servo motor is run to make the output end of the servo motor drive the same-direction threaded rod to rotate.

When the second threaded connector moves to the left, it will drive the connected scraper to move together. Through the movement of the scraper, the waste chips accumulated on the upper end of the laser bracket are pushed to the inside of the collection box for collection, reducing the subsequent cleaning workload.
