[0022] Please refer to Figures 1-4, Embodiments provided by the present utility model: A trimming device, including a workbench 1, two gantry frames 2 are symmetrically and fixedly arranged at the top end of the workbench 1, a cylinder 1 3 is fixedly arranged in the middle of the two gantry frames 2 through bolts, the output ends of the cylinder 1 3 all penetrate through the gantry frames 2 and are fixedly provided with a guide rail frame 4 through couplings for supporting and limiting. A plurality of rotating rods 5 are rotatably connected to the side wall of the guide rail frame 4 through bearings. The plurality of rotating rods 5 are symmetrically distributed. Both ends of the rotating rod 5 penetrate through the side wall of the guide rail frame 4, improving the stability of the rotation of the rotating rod 5. Connecting rods 7 are sleeved on the outer surfaces of the rotating rods 5. Support feet 8 are fixedly arranged at the bottom ends of the connecting rods 7 through welding. A cylinder 2 6 is fixedly arranged at the end of the guide rail frame 4 through bolts. A toothed plate 12 is fixedly arranged at the output end of the cylinder 2 6. A notch 11 is opened inside the toothed plate 12 for the toothed plate 12 to slide. The toothed plate 12 is in a convex shape, and the external dimensions of the toothed plate 12 are adapted to the internal dimensions of the top of the notch 11. The notch 11 penetrates through the end of the guide rail frame 4 away from the rotating rod 5, improving the stability of the sliding of the toothed plate 12. Starting the cylinder 1 3 can drive the guide rail frame 4 to move vertically downward, so that the three support feet 8 support on the surface of the medium-thick plate in sequence to prevent the medium-thick plate from sliding during cutting. Gears 15 are sleeved at the middle positions of the rotating rods 5 close to the connecting rods 7. The gears 15 are sequentially engaged at the bottom end of the toothed plate 12. The connecting rod 7 is in a U shape and is fixedly connected with the rotating rod 5, the support foot 8 and the gear 15 to form an integral structure. The external dimensions of the connecting rod 7 are adapted to the internal dimensions of the bottom end of the notch 11, improving the stability of the rotation of the connecting rod 7. The operator reversely drives the cylinder 1 3 to drive the guide rail frame 4 and the support foot 8 to lift upward. The cylinder 2 6 is started synchronously with the cylinder 1 3, thereby pushing the toothed plate 12 to slide horizontally inside the notch 11, thereby driving the gear 15 to rotate, thereby driving the three rotating rods 5 to rotate synchronously in the guide rail frame 4, thereby driving the connecting rod 7 and the support foot 8 to rotate synchronously, generating a horizontal frictional force on the surface of the medium-thick plate, driving the medium-thick plate to move horizontally inside the workbench 1, thereby realizing the adjustment of the position of the medium-thick plate. Then reversely drive the rotating rod 5 and the cylinder 1 3 to reset the support foot 8 to support on the surface of the medium-thick plate, improving the convenience of trimming and positioning of the medium-thick plate, thereby improving the trimming efficiency of the medium-thick plate.

[0023] The top end of the workbench 1 is in a U shape for the medium-thick plate to be clamped. A servo motor 9 is fixedly arranged at the middle position of the side wall of the workbench 1. A cutter head 10 is fixedly arranged at the output end of the servo motor 9. The cutter head 10 is parallel to the inner side wall of the workbench 1. Starting the servo motor 9 can drive the cutter head 10 to rotate for cutting and grinding the edge of the medium-thick plate. A notch 16 is opened at the surface position of the workbench 1 close to the cutter head 10. The notch 16 penetrates through the surface of the workbench 1 to facilitate the falling of the cut debris, improving the convenience of debris collection.

[0024] On the side wall of the workbench 1 away from the servo motor 9, a third cylinder 13 is fixedly installed. The output end of the third cylinder 13 penetrates through the side wall of the workbench 1 and is fixedly installed with a side plate 14 through a coupling. The external dimensions of the side plate 14 are adapted to the internal dimensions of the workbench 1, which improves the usage range of the trimming device. Starting the first cylinder 3 can drive the side plate 14 to move horizontally, so as to adjust the internal dimensions of the workbench 1, which is convenient for adapting to process medium-thick plates with different widths and improves the processing range of the trimming device.

[0025] Working principle: When this trimming device is in use, the operator first externally connects the power supply, places the medium-thick plate in the middle of the workbench 1, starts the first cylinder 3, which can drive the guide rail frame 4 to move vertically downward, so that the three support feet 8 support on the surface of the medium-thick plate in sequence. Then start the servo motor 9 to drive the cutter head 10 to rotate, so as to realize the trimming process of the medium-thick plate. By reversely driving the first cylinder 3 to drive the guide rail frame 4 and the support feet 8 to lift upward, the second cylinder 6 and the first cylinder 3 are started synchronously, so as to push the toothed plate 12 to slide horizontally inside the first notch 11, so as to drive the gear 15 to rotate, so as to drive the three rotating rods 5 to rotate synchronously in the guide rail frame 4, so as to drive the connecting rod 7 and the support feet 8 to rotate synchronously, so as to generate a horizontal friction force on the surface of the medium-thick plate, so as to drive the medium-thick plate to move horizontally inside the workbench 1. Then reversely drive the rotating rod 5 and the first cylinder 3 to make the support feet 8 reset and support on the surface of the medium-thick plate, thus improving the trimming efficiency of the medium-thick plate.

[0026] Secondly, starting the first cylinder 3 can drive the side plate 14 to move horizontally, so as to adjust the internal dimensions of the workbench 1, which is convenient for adapting to process medium-thick plates with different widths and improves the processing range of the trimming device.
