[0024] Specifically, the hydraulic cylinder 2 is started to drive the connecting rod 3 to move, thereby driving the first rack plate 4 to move. When the first rack plate 4 moves, it drives the first gear 5 to rotate, thereby driving the first rotating shaft 6 to rotate. The rotation of the first rotating shaft 6 drives the fixed column 8 and the base plate 9 to rotate, so that the metal parts that have been coded between the base plate 9 and the cover plate 12 are flipped over. At this time, the barcode scanner below scans the code to check whether the metal parts are qualified, thereby reducing the number of disassembly steps for workers and improving work efficiency.

[0025] Reference Figure 1-Figure 2 The limiting assembly includes a concave limiting block 13, the lower surface of the concave limiting block 13 is fixedly connected to the upper surface of the base 1, the lower surface of the first rack plate 4 is rotatably connected to a rotating column 14, and the outer wall of the rotating column 14 is rotatably connected to the inner wall of the concave limiting block 13;

[0026] Specifically, when the first rack plate 4 moves, the rotating column 14 below will move inside the concave limit block 13 to prevent the moving direction of the first rack plate 4 from changing and causing the first rack plate 4 to fail to operate normally.

[0027] Reference Figure 1 and Figure 2-Figure 4 The upper surface of the base 1 is fixedly connected to a connecting plate 15, and the outer wall of the connecting plate 15 is fixedly connected to a frame 16; the outer wall of the frame 16 is fixedly connected to a first motor 17, and the output end of the first motor 17 is fixedly connected to a second rotating shaft 18; the outer wall of the second rotating shaft 18 is fixedly connected to a first bevel gear 19, and the outer wall of the first bevel gear 19 is meshedly connected to a second bevel gear 20; the interior of the second bevel gear 20 is fixedly connected to a third rotating shaft 21, the interior of the third rotating shaft 21 is fixedly connected to a second gear 22, and the outer wall of the second gear 22 is meshedly connected to a second rack plate 23;

[0028] Specifically, at this time, the first motor 17 is started to drive the second rotating shaft 18 to rotate, thereby driving the first bevel gear 19 to rotate. The rotation of the first bevel gear 19 drives the second bevel gear 20 to rotate, thereby driving the third rotating shaft 21 to rotate. While the third rotating shaft 21 rotates, it drives the second gear 22 to rotate on the surface of the second rack plate 23. Due to the engagement of the second gear 22 and the second rack plate 23, the frame 16 is pushed to move, achieving the effect of rapid adjustment according to the position of the inkjet printer.

[0029] Reference Figure 1 and Figure 2-Figure 4The outer wall of the second rack plate 23 is fixedly connected to the outer wall of the connecting plate 15, the inner part of the frame 16 is slidably connected to the limit rod 24, the outer wall of the limit rod 24 is fixedly connected to the outer wall of the connecting plate 15, and the outer wall of the frame 16 is fixedly connected to the second motor 25; the output end of the second motor 25 is fixedly connected to the threaded column 26, the outer wall of the threaded column 26 is threadedly connected to the sliding plate 27, the inner part of the sliding plate 27 is slidably connected to the outer wall of the second rotating shaft 18, and the lower surface of the sliding plate 27 is provided with a code spraying gun 28;

[0030] Specifically, the second motor 25 is started to drive the threaded column 26 to rotate, thereby driving the sliding plate 27 to move, and the inkjet printer 28 prints the code on the metal parts from left to right, making it easier for optical character recognition (OCR) systems and barcode scanners to read accurately.

[0031] Working principle: Pull the cover plate 12 upwards and place the metal parts to be coded in the groove above the bottom plate 9. The spring 11 rebounds and drives the cover plate 12 to move downward on the outer wall of the limit column 10 to achieve the effect of clamping the metal parts. At this time, the first motor 17 on the outer wall of the frame 16 fixed by the connecting plate 15 is started. The first motor 17 drives the second shaft 18 to rotate inside the frame 16. The rotation of the second shaft 18 drives the first bevel gear 19 to rotate. The rotation of the first bevel gear 19 drives the second bevel gear 20 to rotate. The rotation of the second bevel gear 20 drives the first bevel gear 19 to rotate. The three rotating shafts 21 rotate inside the frame 16. When the third rotating shaft 21 rotates, it drives the second gear 22 to rotate on the surface of the second rack plate 23. Due to the engagement of the second gear 22 and the second rack plate 23, the frame 16 is pushed to move. The frame 16 is limited by the limit rod 24 when moving to prevent deviation caused by movement to the left and right, so as to achieve the effect of rapid adjustment according to the position of the inkjet code. The second motor 25 is started again, and the second motor 25 drives the threaded column 26 to rotate. The rotation of the threaded column 26 drives the sliding plate 27 to move on the outer wall of the second rotating shaft 18 When the first rack plate 4 moves, the rotating column 14 below will move inside the concave limit block 13 to prevent the moving direction of the first rack plate 4 from changing, which will cause the first gear 5 to rotate. 5 rotates to drive the first rotating shaft 6 to rotate inside the limiting plate 7, and the rotation of the first rotating shaft 6 drives the fixed column 8 to rotate, and the fixed column 8 rotates the bottom plate 9, so that the metal parts that have been coded between the bottom plate 9 and the cover plate 12 are turned over. At this time, the barcode scanner below scans the code to check whether the metal parts are qualified, thereby reducing the number of workers' disassembly steps and improving work efficiency. The clamp can not only reduce the number of workers' disassembly steps and improve work efficiency, but also achieve the effect of clamping metal parts. Finally, it can achieve the effect of being able to quickly adjust according to the different positions of the coding.
