[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Such as Figure 1 , Figure 2 and Figure 3As shown in the figure, a punching device for facilitating position fixing includes a workbench 1. A bracket 4 is fixedly connected to the workbench 1. A cylinder 6 is fixedly connected to the bracket 4. A punching assembly 7 is movably installed below the cylinder 6. The punching assembly 7 includes a sliding rod 701, an anti-slip pad 702, a punching frame 704, a telescopic screw rod 706, a spring 707, a pressing plate 708, a limiting plate 710, a punching cutter head 712, and a connecting rod 713. The sliding rod 701 is fixedly connected inside the bracket 4. The anti-slip pad 702 is fixedly connected to the workbench 1. The punching frame 704 is movably installed on the sliding rod 701. The telescopic screw rod 706 is movably installed on both sides of the punching frame 704. A spring 707 is movably installed on the telescopic screw rod 706, and the spring 707 is located between the punching frame 704 and the pressing plate 708. The pressing plate 708 is fixedly connected to the lower end of the telescopic screw rod 706. A bottom plate 3 is fixedly connected to the lower part of the workbench 1. The workbench 1 and the bottom plate 3 are fixedly connected by support columns 2. An activity groove 5 is opened on the workbench 1 at a position below the bracket 4. The sliding rod 701 passes through the activity groove 5 and is fixedly connected to the bottom plate 3. The punching assembly 7 further includes a punching hole 703 and a sliding hole 705. The output shaft of the cylinder 6 is fixedly connected to the punching frame 704. The punching hole 703 is opened on the anti-slip pad 702 and the workbench 1. The punching frame 704 is movably installed on the sliding rod 701 through the sliding hole 705. The lower end of the sliding rod 701 is fixedly connected to the bottom plate 3. The punching assembly 7 further includes a rubber pad 709. The rubber pad 709 is fixedly connected to the bottom surface of the pressing plate 708. The punching frame 704 is on the sliding rod 701 and realizes descending and ascending through the drive of the cylinder 6. During the descending process, the pressing plate 708 contacts the metal plate first before the punching cutter head 712, and as the punching frame 704 moves downward, the pressure between the pressing plate 708 and the metal plate is gradually increased, so that the metal plate is fixed on the anti-slip pad 702. When the punching frame 704 ascends, the punching frame 704 synchronously moves upward on the telescopic screw rod 706, and finally the pressing plate 708 is lifted upward by the limiting plate 710, so that the pressure between the pressing plate 708 and the metal plate is gradually reduced and finally separated from the metal plate, enabling the disassembly of the fixing structure, and making the fixing and disassembly of the workpiece in the punching device more time-saving.

[0022] As Figure 1 , Figure 3 and Figure 4As shown, the limiting plate 710 is fixedly connected to the upper position of the telescopic screw rod 706. The punching cutter head 712 is fixedly connected to the bottom surface position of the punching frame 704. Both side rods of the connecting rod 713 are fixedly connected to the pressing plate 708. The punching assembly 7 further includes a locking bolt 711. The locking bolt 711 is movably installed at the side position of the limiting plate 710. A threaded hole is provided at the center position of the limiting plate 710, and it is movably installed with the telescopic screw rod 706 through the threaded hole. The punching assembly 7 further includes a limiting ring 714 and a positioning nut 715. The limiting ring 714 is fixedly connected to both sides of the connecting rod 713. The positioning nut 715 is movably installed on both sides of the limiting ring 714 and is located at the side position of the limiting ring 714. The pressing plate 708 is located between the limiting ring 714 and the positioning nut 715. The limiting ring 714 moves movably on the telescopic screw rod 706, and the limiting plate 710 is fixed by the locking bolt 711, so that the initial height of the pressing plate 708 and the initial tightness of the spring 707 can be adjusted movably. After the limiting plate 710 is disassembled, the structures such as the telescopic screw rod 706 are convenient to disassemble, making maintenance and repair more convenient. Moreover, the connecting rod 713 connects the pressing plates 708 on both sides into a whole, making the stability of the pressing plate 708 higher.

[0023] It should be noted that the present utility model is a punching device for facilitating position fixing. The metal plate is placed on the anti-slip pad 702, and then the cylinder 6 is started. The output shaft of the cylinder 6 pushes the punching frame 704 downward. The punching frame 704 moves downward on the sliding rod 701 through the sliding hole 705. The pressing plate 708 on the punching frame 704 is located below the punching cutter head 712. The pressing plate 708 and the rubber pad 709 first contact both sides of the metal plate, and then as the punching frame 704 continues to move, the telescopic screw rod 706 moves upward in the punching frame 704, and the spring 707 on the telescopic screw rod 706 is compressed, so that the pressure of the pressing plate 708 and the rubber pad 709 on the metal plate increases. When the punching cutter head 712 contacts the metal plate, punching processing starts. After punching is completed, the cylinder 6 returns to its original position. The punching frame 704 moves upward on the sliding rod 701, and the punching frame 704 synchronously moves upward on the telescopic screw rod 706, thereby gradually releasing the spring 707, so that the pressure of the pressing plate 708 and the rubber pad 709 on the metal plate gradually decreases. When the punching frame 704 moves to the position below the limiting plate 710, due to the blocking of the limiting plate 710, the punching frame 704 lifts the telescopic screw rod 706, the pressing plate 708 and the rubber pad 709 upward, so that the pressing plate 708 and the rubber pad 709 leave the metal plate, facilitating the replacement of a new metal plate. This punching assembly 7 enables the fixing of the metal plate to be completed synchronously during the descent and ascent of the punching frame 704, saving time and improving work efficiency when punching metal plates in batches.

[0024] The foregoing has shown and described the basic principles, main features and advantages of the present utility model.
