DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-3 As shown, in the utility model, a positioning roller 1 is provided to position the plate processed by the cutting machine, and two positioning rollers 1 are provided, and the two ends of the positioning roller 1 are respectively fixedly connected to the top of the slide plate 2, and the slide plate 2 passes through the slide groove 4 on the workbench 3. The slide plates 2 on both sides are fixedly connected by connecting rods 5, and a lifting plate 6 is provided between the two connecting rods 5. The ends of the lifting plate 6 are slidably matched with the connecting rods 5 on both sides, and the middle part of the lifting plate 6 is fixedly connected to the top of the lifting and telescopic shaft 7. The height of the lifting plate 6 is adjusted by the extension and contraction of the lifting and telescopic shaft 7, and the height of the connecting rod 5 and the slide plate 2 and the positioning roller 1 above the connecting rod 5 are adjusted by the lifting plate 6. The positioning roller 1 can be lowered to fix the plate on the workbench 3 of the cutting machine, and the positioning roller 1 can be lifted to release the plate on the workbench 3.

[0018] The bottom end of the lifting and telescopic shaft 7 is fixed on the base 8, and the workbench 3 is fixed above the base 8 through the support rod 9. The lifting and lowering of the positioning roller 1 is adjusted by the extension and retraction of the lifting and telescopic shaft 7. During the lifting and lowering of the positioning roller 1, the slide plate 2 moves up and down in the slide groove 4.

[0019] The slide plate 2 is slidably matched with the slide groove 4, and a distance-adjusting telescopic shaft 10 is arranged between the two groups of connecting rods 5. The extension and retraction of the distance-adjusting telescopic shaft 10 can drive the slide plates 2 at both ends of the distance-adjusting telescopic shaft 10 to be relatively lifted, thereby adjusting the distance between the two groups of positioning rollers 1 connected to the slide plate 2 to adapt to the positioning of plates of different specifications.

[0020] A positioning plate 11 is provided on the lower surface of the workbench 3 outside the slide groove 4, and a positioning screw 12 is provided on the positioning plate 11. The slide plate 2 can be fixed at a certain position of the workbench 3 by the positioning screw 12 to prevent the positioning roller 1 from moving when positioning the plate.

[0021] A driving groove 13 is provided in the middle of the connecting rod 5, and the two ends of the lifting plate 6 are respectively inserted into the driving grooves 13 on the two connecting rods 5. During the extension and retraction process of the distance adjustment telescopic shaft 10, the connecting rod 5 can slide along the lifting plate 6, so that the horizontal movement and vertical lifting of the slide plate 2 are relatively independent.
