Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a gantry-type fiber laser cutting machine. Background Technology

[0002] Laser cutting uses an invisible beam of light instead of a traditional mechanical blade. It features high precision, fast cutting speed, no limitation on cutting patterns, automatic layout to save materials, smooth cuts, and low processing costs. It will gradually improve upon or replace traditional metal cutting equipment.

[0003] For example, the existing Chinese utility model patent with publication number "CN221158971U" discloses a fiber laser cutting machine with a waste chip collection function, specifically relating to the field of laser cutting machines. It includes a fiber laser cutting machine body, with a support leg fixed to the bottom of the machine body, and support feet installed at the bottom of the support leg. This device is equipped with a locking device that collects waste chips generated during the laser cutting process through the waste chip collection housing. Simultaneously, it facilitates the removal of the positioning block from the positioning groove, releasing the locking of the positioning housing and the waste chip collection housing, thus simplifying cleaning and allowing easy removal of the waste chip collection housing for disposal. The device also includes a stabilizing device; the stabilizing sleeve at the bottom of the metal column can fit against the top of the waste chip collection housing, where the guide block provides guidance and improves the stability of the waste chip collection housing during collection. However, the above-mentioned cutting machine still has some shortcomings:

[0036] In practical use, the welded part is placed on the roller conveyor 2 and moved by the roller conveyor 2. After the welded part is moved to the designated position, the first motor 8 is started, which drives the bidirectional threaded rod 6 to rotate. The bidirectional threaded rod 6 drives the two sets of first moving seats 9 to move closer together, so that the two sets of positioning frames 11 move closer together and contact the side of the welded part. Then, the second motor 17 is started, which drives the drive shaft 18 to rotate.

The worm wheels 15 drive the first lead screw 13 to rotate. The first lead screw 13 drives the clamping plate 14 to move down and press and fix the welded part. The anti-slip pad 32 increases the friction between the welded part and the clamping plate 14, improving the fixing effect of the cut part. After the cut part is fixed, the laser cutting head 20 can be used for cutting. During cutting, the dust suction pipe 23 is used in conjunction with external dust suction equipment to remove the waste generated during the welding process. The laser cutting head 20 can be moved along the X and Y directions respectively by the X-axis and Y-axis moving components, and the height of the laser cutting head 20 can be adjusted by the hydraulic cylinder 22. A protective shell 21 protects the laser cutting head 20 and shields it, thus preventing eye damage from laser cutting. Furthermore, to prevent the protective shell 21 from interfering with the operator's observation of the laser cutting head 20's working status, a coated tempered glass protective observation window 31 is also provided on the protective shell 21.

[0037] In summary, this solution includes a positioning component 3, which facilitates automatic fixation of the welded parts and meets the fixation requirements of welded parts of different sizes; a roller conveyor 2, which facilitates automatic loading and unloading of the welded parts, saving time and labor; a protective shell 21 and a coated tempered glass protective observation window 31, which shield the laser cutting head 20 during the welding process, preventing workers from looking directly at it and preventing eye damage, while the coated tempered glass protective observation window 31 allows for easy observation of the working status of the laser cutting head 20; and a dust suction pipe 23 and a dust suction head 24, which can be used in conjunction with external dust collection equipment to remove waste generated during the welding process.
