When the angle adjustment plate 3 is adjusted, the angle adjustment plate 3 can drive the second punching seat 22 to rotate synchronously through the L-shaped connecting plate 23, so that the punching head 16 of the punching mechanism on the guide plate 4 is always aligned with the second punching seat 22, thereby ensuring the reliability of oblique punching.

[0048] Example 6

[0049] On the basis of any one of Examples 3-5, Figure 3-Figure 5 As shown, the connecting mechanism includes a sliding plate 24, which is slidably arranged in the mounting hole 17, and the sliding plate 24 is connected to the inner wall of the mounting hole 17 through a connecting spring 25. A plug-in column 26 is arranged on the side of the sliding plate 24 close to the connecting column 19, and a plug-in hole 27 corresponding to the plug-in column 26 is arranged in the connecting column 19. The plug-in column 26 extends into the plug-in hole 27 away from one end of the sliding plate 24, and a plurality of card grooves 28 are arranged on the inner wall of the plug-in hole 27. A mounting cavity 29 is arranged in the plug-in column 26, and a servo motor 30 is arranged in the mounting cavity 29. A double-headed screw 31 is arranged at the output end of the servo motor 30, and the double-headed screw 31 is far away from the output end of the servo motor 30. One end of the servo motor 30 is rotatably connected to the inner wall of the installation cavity 29, and the threads of the two ends of the double-headed screw 31 are rotated in opposite directions. The two ends of the double-headed screw 31 are respectively threadedly connected with a moving block 32. A card column 33 is slidably arranged in the slot 28. The end of the card column 33 away from the slot 28 passes through the outer wall of the plug-in column 26 and extends into the installation cavity 29. The card column 33 is slidably connected with the plug-in column 26 through the position. The moving block 32 is connected to the end of the card column 33 away from the slot 28 through a connecting rod 34. One end of the connecting rod 34 is hingedly connected to the end of the card column 33 away from the slot 28, and the other end of the connecting rod 34 is hingedly connected to the side wall of the moving block 32;

[0050] Baffles 35 are respectively arranged at the front and rear ends of the slide seat 15 . The baffles 35 are L-shaped, and the mounting plate 18 is slidably connected to the inner wall of the baffles 35 .

[0051] The working principle and beneficial effects of the above technical solution are as follows: when installing the punching head 16, the clamping column 33 is located in the plug-in column 26, and the mounting plate 18 is first inserted between the two baffles 35, and the mounting plate 18 is restricted from sliding outward of the baffle 35 by one end of the baffle 35, and then the mounting plate 18 is pushed toward the plug-in hole 27, so that the plug-in column 26 enters the plug-in hole 27. At this time, the two clamping columns 33 are both located in the plug-in column 26, and after the plug-in column 26 contacts the innermost wall of the plug-in hole 27, the servo motor 30 is started, and the rotation of the servo motor 30 drives the double-headed screw 31 to rotate, and the rotation of the double-headed screw 31 drives the two moving The blocks 32 move in the direction of approaching each other, thereby driving the card column 33 to move in the direction of approaching the card slot 28 through the connecting rod 34, so that the card column 33 is inserted into the card slot 28, and then the servo motor 30 stops working. At this time, the plug-in column 26 is installed in the plug-in hole 27, and the connecting column 19 is located in the mounting hole 17. When punching, the punching head 16 first contacts the water tank puzzle board, and then drives the connecting column 19 to slide in the mounting hole 17 through the mounting plate 18. The connecting column 19 drives the plug-in column 26 to move through the plug-in hole 27, and the plug-in column 26 drives the sliding plate 24 to slide in the mounting hole 17, and the connecting spring 25 is compressed until When the mounting plate 18 contacts the slide 15, the punching head 16 can complete the punching under the pushing action of the hydraulic cylinder 14. After the punching is completed, the hydraulic cylinder 14 contracts to drive the slide 15 to move, and the connecting spring 25 first returns to its original position, and then stretches under the friction between the punching head 16 and the hole, until the mounting plate 18 contacts the end of the baffle 35 away from the slide 15, and the mounting plate 18 and the punching head 16 are driven to move away from the water tank puzzle through the support of the baffle 35, so that the punching head 16 is separated from the water tank puzzle. Under the action of the baffle 35, there will be no large force between the clamping column 33 and the clamping groove 28, which is effective. The card column 33 is protected and the service life of the card column 33 is extended. When replacing the punching head 16 according to punching processing of different sizes, it is only necessary to start the servo motor 30 and control the double-headed screw 31 to rotate in the opposite direction, so that the two moving blocks 32 move away from each other, and the card column 33 is separated from the card slot 28. At this time, the connecting column 19 can be pulled out from the mounting hole 17, and then the mounting plate 18 can be slid out from between the two baffles 35, so as to realize the rapid replacement of the punching head 16, reduce the downtime for replacement, improve the punching efficiency, and do not need punching devices of various sizes of punching heads 16, saving costs.
