A rotating plate 607 is fixed on the outer surface of the rotating shaft 606 and located at the rear side of the second gear 605. A connecting rod 608 is fixed to one end of the back side of the rotating plate 607. An inclined frame 609 is provided on the outer surface of the connecting rod 608. The rotation of the rotating shaft 606 rotates the rotating plate 607, and the rotation of the rotating plate 607 drives the connecting rod 608 fixed on the back side thereof to rotate. The connecting rod 608 moves in the inner cavity of the inclined frame 609 and drives the inclined frame 609 to move. Linkage frames 610 are fixed on the opposite sides of the inclined frames 609 at the left and right ends, and plug blocks 611 are fixed on the opposite sides of the two linkage frames 610.

[0026] When the inclined frame 609 moves backward, it will drive the linkage frame 610 to move backward, so that the insertion block 611 moves out of the inner cavity of the slot and moves to the inner cavity of the connecting seat 4. At this time, the sleeve rod is on the outer surface of the limit rod, so that the connection block 602 can be released from the restriction, and the connection block 602 can be taken out to unscrew the cutting head 5 and replace it with a new one.

[0027] Among them, the size of the inner cavity of the installation groove 601 is adapted to the size of the connecting block 602, the front side of the rotating rod 603 passes through the connecting seat 4 and extends to the front side of the connecting seat 4, the shape of the inclined frame 609 is a parallelogram with a hollow interior, and the two inclined frames 609 are fixed with sleeve rods on the opposite sides, and the opposite sides of the left and right side walls of the inner cavity of the connecting seat 4 are fixed with limit rods, and the sleeve rod and the limit rod are slidably connected and inseparable from each other.

[0028] In this embodiment, slots matching the size of the plug block 611 are provided on the left and right sides of the connecting block 602, and limit strips are fixed on the left and right ends of the opposite sides of the inner top wall and the inner bottom wall of the connecting seat 4. The top and bottom of the linkage frame 610 both make horizontal linear motion in the inner cavity of the limit strip, and the cross-sectional shape of the linkage frame 610 is an inverted T shape.

[0029] It should be noted that the disassembly and replacement mechanism 6 is provided to facilitate the staff to replace the cutting head 5, thereby improving the cutting effect of the automobile bumper bracket. The left and right side walls of the inner cavity of the installation groove 601 are provided with guide holes that are compatible with the size of the plug block 611.

[0030] See also Figure 4 In order to collect the waste chips generated by cutting, the collection mechanism 7 in this embodiment includes a chip feed hole 701 opened in the middle of the upper surface of the support table 1, and the inner cavity of the chip feed hole 701 is fixed with a support net 702, and the inner cavity of the support table 1 is placed with a collection box 703, and the right side wall of the inner cavity of the support table 1 is fixed with a fan 704, and the air inlet end of the fan 704 is fixed to the right side of the collection box 703 and connected with its inner cavity. When the fan 704 is started, the air inlet end of the fan 704 draws the waste chips falling on the surface of the support net 702 into the inner cavity of the collection box 703 through the chip feed hole 701, and the waste chips can be collected by the collection box 703.

[0031] Among them, the size of the inner cavity of the collection box 703 is larger than the size of the chip feed hole 701, and the left end of the outer surface of the support platform 1 is hingedly connected to a sealing door through a door hinge. A filter is fixed to the inner cavity of the air inlet end of the fan 704. The filter can prevent waste chips from entering the inner cavity of the fan 704, thereby preventing the normal operation of the fan 704 from being affected.

[0032] The working principle of the above embodiment is:

[0033] (1) When replacing the cutting blade 5, first rotate the rotating rod 603. The rotation of the rotating rod 603 drives the No. 1 gear 604 to rotate. The rotation of the No. 1 gear 604 causes the No. 2 gear 605 to rotate. The rotation of the No. 2 gear 605 drives the rotating shaft 606 to rotate. The rotation of the rotating shaft 606 causes the rotating plate 607 to rotate. The rotation of the rotating plate 607 drives the connecting rod 608 fixed on the back thereof to rotate. The connecting rod 608 moves in the inner cavity of the inclined frame 609 and drives the inclined frame 609 to move. When the inclined frame 609 moves in reverse, it drives the linkage frame 610 to move in reverse, thereby causing the insert block 611 to move out of the inner cavity of the slot and move to the inner cavity of the connecting seat 4. At this time, the sleeve rod is on the outer surface of the limit rod, thereby being able to release the restriction on the connecting block 602, and taking out the connecting block 602 to unscrew the cutting blade 5 and replace it with a new one.

[0034] (2) When the cutting head 5 cuts the car bumper, the car bumper bracket is placed on the upper surface of the support platform 1. The electric push rods on both sides can be started, and the output shafts of the electric push rods can push the two clamping plates to make relative movements, so that the car bumper bracket can be clamped by the two clamping plates. Then, the dual-axis linear module 3 can be started to cut the car bumper through the cutting head 5. A lot of waste chips will be generated during cutting. In order to facilitate cleaning by the staff, the fan 704 is first started. The air inlet end of the fan 704 draws the waste chips falling on the surface of the support net 702 into the inner cavity of the collection box 703 through the chip inlet hole 701, and the waste chips can be collected by the collection box 703.
