[0036] Based on the above Embodiment 1, please refer to the appendix Figure 4 , a sliding sleeve 24 is installed at the rear end of the clamping member 241. The sliding sleeve 24 is slidably connected to the propulsion table 23. A through positioning hole 28 is provided at the upper end of the sliding sleeve 24. A plurality of equally spaced adjustment holes 27 are provided at the upper end of the propulsion table 23. The sliding sleeve 24 and the propulsion table 23 are fixed by a positioning pin 26 passing through the positioning hole 28 and the adjustment hole 27. The sliding sleeve 24 can be fixed at a position above any one of the adjustment holes 27 through the positioning pin 26. A through second limiting groove is provided in the middle of the propulsion table 23. A second limiting slider 243 is installed in the sliding sleeve 24. The second limiting slider 243 is slidably connected and matched with the second limiting chute 231. After the sliding sleeve 24 loses the restriction of the positioning pin 26, it can horizontally slide on the propulsion table 23 through the second limiting slider 243 without deviation.

[0037] Please refer to the appendix Figure 2 , the size adjustment assembly 4 includes an adjustment cylinder 41 fixed to the upper end of the sliding table 21. The adjustment cylinder 41 is electrically connected to the controller 6. An adjustment frame 42 fixedly connected to the propulsion table 23 is installed at the output end of the adjustment cylinder 41;

[0038] In this embodiment, the distance between the clamping members 241 for clamping the board on the propulsion table 23 can be adjusted by changing the position of the sliding sleeve 24, and the width of the clamped board can be preset. The specific adjustment size is known. The positioning holes 28 on the propulsion table 23 are equally spaced, so that the position of the board can be predicted and known after the adjustment. When adjusting the position of the cutting machine 55, it needs to be adaptively changed according to the position of the board. The adjustment cylinder 41 can change the position of the propulsion shaft 32 to adjust the length of the clamped board. The adjustment cylinder 41 is fixed by the controller 6. The adjustable parameter is the position of the propulsion table 23 within the fixed frame 22, and the change value of the fixed length of the board can be accurately regulated through the control of the controller 6.

[0039] Working principle and usage process of the utility model: Before use, adjust the position of the sliding sleeve 24 according to the width of the plate to be cut. After removing the positioning pins 26 on one or both of the two sliding sleeves 24, slide the sliding sleeve 24 along the advancing table 23 to the position corresponding to the adjustment hole 27 and align the positioning hole 28 on the sliding sleeve 24 with the adjustment hole 27. The distance between the clamping members 241 on the sliding sleeve 24 changes accordingly. Then insert the positioning pin 26 into the positioning hole 28 and the adjustment hole 27 to fix the sliding sleeve 24. Then adjust the position of the advancing table 23 according to the length of the plate to be cut. After inputting the length parameter corresponding to the plate through the controller 6, the adjusting cylinder 41 drives the advancing table 23 to move within the fixed frame 22 through the adjusting frame 42;

[0040] During cutting, place the plate between the clamping members 241 and the baffle 25 within the fixed frame 22. The distance between the clamping members 241 and the position of the advancing table 23 have been adjusted, so the plate of the corresponding size can just be clamped between the clamping members 241 and the baffle 25 and remain fixed. Then adjust the position of the cutting machine 55 according to the cutting requirements. After determining the position of the plate, start the servo motor 52 by inputting the control parameters through the controller 6. The servo motor 52 drives the driving screw 53 to rotate to move the mounting slide 54, and the mounting slide 54 drives the cutting machine 55 to move to the set position. Then, after inputting and setting the output value of the advancing cylinder 31 according to the length of the plate through the controller 6, perform cutting. After the advancing cylinder 31 is started through the controller 6, it drives the sliding table 21 to move towards the cutting machine 55 through the transmission frame 33 and the telescopic slide rail. The sliding table 21 drives the fixed frame 22 and the plate clamped within the fixed frame 22 to move. At this time, the cutting tool of the cutting machine 55 passes through the cutting groove 251 on the baffle 25 to cut the plate. When it is necessary to cut off the plate, the cutting tool will finally enter the cutting groove 242 on the clamping member 241. After the advancing cylinder 31 outputs to the set preset value, it stops and retracts under the programming control program of the controller 6 and drives the sliding table 21 and the fixed frame 22 to move back to the original position to complete the cutting.
