[0030] When cutting the frame 12, firstly, the telescopic cylinder 601 is activated. The output end of the telescopic cylinder 601 shortens, causing the fixing rod 607 to rotate towards the robot 3. At this time, both ends of the frame 12 are placed into the grooves of the concave support platform 604. The output end of the telescopic cylinder 601 extends, causing the fixing rod 607 to rotate closer to the frame 12. The rubber blocks 609 are used to fix both ends of the frame 12. Then, the telescopic cylinder 606 is activated. The output end of the telescopic cylinder 606 shortens, and the fixing rod 608 rotates away from the frame 12. At this time, the position of the concave support platform 605 is adjusted by moving the push-pull clamp 611 on the triangular plate 610. The concave support platform 605 is adjusted according to the position of the middle part of the frame 12 to support the middle part of the frame 12 smoothly, which can adapt to the cutting and processing of complex frames 12.
