[0026] At the same time, adjusting mechanisms 3 are arranged on the left and right sides of the cross frame 21, the adjusting mechanisms 3 are used to limit and fix the metal plate;

[0027] As shown in the drawings, the present application provides a positioning workbench for laser cutting of metal plates, comprising a rack 1, and a cutting table 11 mounted on the rack 1, the cutting table 11 is used to place the metal plate to be cut; Figures 1-3 ​As shown in the figure, the slide rail 13 is fixed on the rack 1 at the side of the guide rail 12, and two sets of adjusting mechanisms 3 are arranged on the slide rail 13 (as shown in the figure) Figure 1 With Figure 2 As shown in the figure), the adjusting mechanism 3 has a beam frame 31 in sliding connection with the slide rail 13, and the two sets of beam frames 31 are respectively arranged at the two sides of the cross frame 21, and the beam frame 31 is adapted to slide along the slide rail 13 under the action of external driving;

[0028] Two sets of sliding blocks 34 are slidingly installed on the beam frame 31, and the two sets of sliding blocks 34 are adapted to slide on the beam frame 31 and approach or move away from each other, and a double-headed screw 32 is bearingly installed on the beam frame 31, the double-headed screw 32 penetrates through the two sets of sliding blocks 34, and the double-headed screw 32 has positive and reverse threads, the two sets of sliding blocks 34 are respectively connected with the positive and reverse threads of the double-headed screw 32, and the end of the double-headed screw 32 is connected with a motor 33, the motor 33 is adapted to drive the double-headed screw 32 to rotate, and under the action of the double-headed screw 32, the two sets of sliding blocks 34 are driven to approach or move away from each other;

[0032] Then the external driving force drives the beam frames 31 to approach each other, and drives the straightening units 4 to approach the corners of the metal plate. In this process, the first end 421 of the bending rod 42 abuts against the metal plate. Then, under the continuous driving of the two sets of beam frames 31, the bending rod 42 rotates and drives the second end 422 to move. At this time, the second end 422 rotates and abuts against the side of the metal plate, so that the metal plate is straightened under the cooperation of the first end 421 and the second end 422. After the side where the first end 421 is located on the bending rod 42 is parallel to the top frame 41, the straightening of the metal plate is completed.
