Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Such as Figures 1-9As shown in the figure, the end-edge positioning and follow-up pressing mechanism for the grooving machine includes: a moving base 1, a linear guide rail 2, a guide rail slider 3, a moving seat 4, a bearing seat 5 and a lead screw 6. A pressing assembly 7 is provided at the upper end of the moving seat 4. The pressing assembly 7 includes a bottom plate 8, a support plate 9, a pressing block 10 and a cylinder 11. The bottom plate 8 is provided with a support plate 9 and a cylinder 11 at the upper end. The support plate 9 is provided with a moving groove 12 and a bearing portion 24. A guide rod 13 is provided in the moving groove 12. A pressing block 10 is slidably arranged in the moving groove 12. The pressing block 10 is slidably connected to the guide rod 13. The pressing block 10 is connected to the output end of the cylinder 11. The bottom surface of the pressing block 10 is arranged parallel to the bearing portion 24. A groove 14 and a rubber protective pad 15 are provided at the bottom of the pressing block 10. An ejecting structure 25 is provided in the groove 14. The device is connected and fixed to the machine table by using the moving base 1. A known external motor can drive the lead screw 6 to rotate, which is convenient for adjusting the position of the moving seat 4 slidably connected to the linear guide rail 2. The cylinder 11 is a prior art. By providing the pressing assembly 7, the bottom plate 8, the support plate 9, the pressing block 10, the cylinder 11, the moving groove 12, the guide rod 13, the groove 14 and the rubber protective pad 15, the bearing portion 24 at the upper end of the support plate 9 cooperates with the pressing block 10 to clamp and fix the plate. When the end edge of the plate is placed on the upper end of the bearing portion 24, the cylinder 11 drives the pressing block 10 to move down along the guide rod 13. The bottom surface of the pressing block 10 is arranged parallel to the bearing portion 24, which can increase the contact area between the pressing block 10 and the plate, reduce the damage to the plate and enhance the stability of pressing the plate at the same time. The rubber protective pad 15 provided at the bottom of the pressing block 10 can prevent the plate from leaving indentations when being pressed by the pressing block 10, improve the appearance quality of the product and reduce defective products. When the plate processing is completed, the cylinder 11 drives the pressing block 10 to move up along the guide rod 13, which is convenient for taking out the remaining plate.

[0027] The ejection structure 25 includes an ejection block 16 and an ejection spring 17. The ejection block 16 is slidably arranged in the groove 14, and an ejection spring 17 is arranged between the ejection block 16 and the top of the groove 14. When the ejection spring 17 is in its natural state, the height of the bottom of the ejection block 16 is lower than the height of the bottom of the rubber protection pad 15. The depth of the groove 14 is larger than the thickness of the ejection block 16. There are two groups of grooves 14 provided at the bottom of the pressing block 10, and an ejection structure 25 is arranged in each group of grooves 14. A communication limiting groove 19 is arranged between the two groups of grooves 14, and a connecting rod 20 is slidably arranged in the communication limiting groove 19. Both ends of the connecting rod 20 are fixedly connected to the two ejection blocks 16 respectively. The heights of the bottoms of the two ejection blocks 16 are the same. Four ejection springs 17 are arranged in each group of grooves 14. By arranging the ejection structure 25, the ejection block 16, the ejection spring 17, the communication limiting groove 19 and the connecting rod 20, when the air cylinder 11 drives the pressing block 10 to move downward along the guide rod 13, the bottom of the pressing block 10 first contacts the edge of the plate. As the pressing block 10 continues to press down, the ejection spring 17 can be compressed and deformed, and at the same time, the ejection block 16 slides into the groove 14. The pressing block 10 continues to move downward until the bottom of the rubber protection pad 15 contacts the edge of the plate, and the plate is pressed and fixed by the pressing block 10. After the plate processing is completed, the air cylinder 11 drives the pressing block 10 to move upward along the guide rod 13. When the pressing block 10 moves upward, the ejection spring 17 resets and drives the ejection block 16 to move downward to eject, and the elastic force of the ejection spring 17 can be used to separate the plate from the rubber protection pad 15 at the bottom of the pressing block 10, which is convenient for taking out the plate.

[0028] Two groups of pressing assemblies 7 are arranged at the upper end of the moving seat 4. An adjusting groove 21 is arranged at the upper end of the moving seat 4, and a double-headed screw rod 22 is rotatably arranged in the adjusting groove 21. Both ends of the double-headed screw rod 22 are threadedly connected to the two bottom plates 8 respectively. The double-headed screw rod 22 is connected to the output end of the motor 23. The thread directions at both ends of the double-headed screw rod 22 are opposite. By arranging the two groups of pressing assemblies 7, the adjusting groove 21, the double-headed screw rod 22 and the motor 23, the motor 23 is a prior art and is connected to an external known power source. The two bottom plates 8 at the upper end of the moving seat 4 are both slidably connected to the adjusting groove 21. The motor 23 can be used to drive the double-headed screw rod 22 to rotate, so that the two groups of pressing assemblies 7 approach or move away from each other, which is convenient for adjusting the distance between the two groups of pressing assemblies 7 at the upper end of the same moving seat 4 and is convenient for pressing and fixing plates of different sizes, and is convenient to use.

[0029] The working principle of the present utility model is as follows: during use, the bearing portion 24 at the upper end of the support plate 9 cooperates with the pressing block 10 to clamp and fix the plate. When the end edge of the plate is placed on the upper end of the bearing portion 24, the cylinder 11 drives the pressing block 10 to move downward along the guide rod 13. The bottom surface of the pressing block 10 is arranged parallel to the bearing portion 24, which can increase the contact area between the pressing block 10 and the plate, reduce the damage to the plate, and enhance the stability of pressing the plate at the same time. A rubber protection pad 15 is arranged at the bottom of the pressing block 10 to avoid leaving indentations on the plate when pressing with the pressing block 10, improve the appearance quality of the product, and reduce defective products. This is the working principle of the device.
