Electric hydraulic cylinders 6 are fixedly installed in the middle of both sides of the cutting seat 4. The telescopic ends of the electric hydraulic cylinders 6 extend into the interior of the convex grooves 7 and are fixedly connected to the side of the corresponding convex sliders 9.

[0023] Specifically, the convex slider 9 is moved by the electric hydraulic cylinder 6, which in turn moves the U-shaped block 5. The U-shaped block 5 moves to bring the two sides of the wing into contact, and the side fixing plate 10 is fixed to the wing tip by the first electric push rod 11.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an automotive wing cutting fixture. The auxiliary positioning component includes two fixing bars 8. The fixing bars 8 are fixedly installed between two columns 2 located on the same side. The side of the fixing bars 8 is provided with a retractable side fixing plate 10. Two T-shaped grooves 21 are symmetrically opened on one side of the fixing bars 8. T-shaped sliders 22 are slidably connected inside the two T-shaped grooves 21. The middle of the two T-shaped sliders 22 is rotatably connected to the connecting rods 24. The ends of the two connecting rods 24 are rotatably connected to the two sides of the back of the side positioning plate 25. A second electric push rod 23 is fixedly installed on one side of the groove wall of the two T-shaped grooves 21. The telescopic end of the second electric push rod 23 is fixedly connected to the side of the T-shaped slider 22.

[0025] Specifically, the second electric push rod 23 pushes the T-shaped slider 22 to move, the movement of the T-shaped slider 22 compresses the connecting rod 24 to rotate, the rotation of the connecting rod 24 pushes the extension and retraction of the side positioning plate 25, and the side positioning plate 25 fixes the two sides of the cut wing.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an automotive wing cutting fixture. Assembly strips 12 are fixedly installed on both sides of the bottom end of the top plate 3. Two limiting rods 13 are fixedly installed between the two assembly strips 12.

[0028] Specifically, through the cooperation of the ball screw 16 and the screw seat 14, the laser cutting head 20 moves horizontally along the X-axis, and the electric slide rail 17 drives the laser cutting head 20 to move horizontally along the Y-axis, thereby realizing the two-dimensional planar cutting of the laser cutting head 20.

[0029] In specific implementation, when using this car wing cutting fixture, firstly, the car wing to be cut is placed between two U-shaped blocks 5. Then, the electric hydraulic cylinder 6 is opened, and the electric hydraulic cylinder 6 pushes the convex slider 9 to move. The movement of the convex slider 9 drives the U-shaped blocks 5 to move, and the U-shaped blocks 5 abut against the two sides of the wing. Next, the first electric push rod 11 is opened, and the first electric push rod 11 pushes the side fixing plate 10 to move. The side fixing plate 10 fixes the two sides of the wing. Then, the second electric push rod 23 is opened, and the second electric push rod 23 pushes the T-shaped slider 22 to move. The movement of the T-shaped slider 22 squeezes the connecting rod 24 to rotate. The rotation of the connecting rod 24 pushes the side positioning plate 25 to move, and the side positioning plate 25 fixes the two sides of the wing. Then, the servo motor 15 and the electric slide rail 17 are turned on. The servo motor 15 drives the ball screw 16 to rotate, the ball screw 16 rotates and drives the screw seat 14 to move, and the electric slide rail 17 drives the slide 18 to move, so as to realize the two-dimensional planar moving cutting of the laser cutting head 20.
