[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0019] This utility model provides a punching device, such as a punching device for a speaker grille decorative ring.

[0020] Includes a workbench 1 and a placement mechanism and a drilling mechanism mounted on the workbench 1. Reference Figures 1-4 The placement mechanism is described in detail as follows: The placement mechanism includes a fixed base 6, a guide rail 7, a movable platform 8, a fixing component 9, and bolts 11. There are two fixed bases 6. The guide rail 7 is fixedly installed on the fixed base 6. The two ends of the movable platform 8 slide along the two fixed bases 6 and the two guide rails 7 respectively, and the movement can be restricted by bolts 11. The fixing component 9 is installed on the movable platform 8. The fixing assembly 9 includes a placement platform 901, a rotating platform 902, a fixing shaft 903, a connecting part 904, a fixing rod 905, a pressure applying part 906, a placement seat 907, a bolt 908, and a cylinder 909. The placement platform 901 rotates on the moving platform 8 via the rotating platform 902. The fixing shaft 903 is fixed at multiple angles to the side of the placement platform 901. The connecting part 904 can slide up and down on the rotating platform 902. The fixing rod 905 is threadedly connected to the connecting part 904. The placement seat 907 is locked to the placement platform 901 by the bolt 908. The pressure applying part 906 can pass through the placement seat 907 and extend to the bottom of the placement platform 901. Its bottom is movably sleeved on the fixing rod 905. The output end of the cylinder 909 is fixedly connected to the bottom of the connecting part 904. The movable stage 8 is also provided with a limiting component 10 to restrict the rotation of the placement stage 901, including a slide 1001, a limiting block 1002 and a limiting shaft 1003. The limiting block 1002 is slidably arranged along the slide 1001. The limiting shaft 1003 is inserted longitudinally into the limiting block 1002 and can pass through the fixed shaft 903 inserted in the limiting block 1002. A through hole is opened in the middle of the limiting block 1002, which is fitted with the fixed shaft 903. After the moving limiting block 1002 moves closer to the placement stage 901, the fixed shaft 903 can pass through the limiting block 1002. After the limiting shaft 1003 is inserted downward from above the limiting block 1002, it can pass through the fixed shaft 903. The bottom of the limiting shaft 1003 can be inserted into the slot on the slide 1001. This stabilizes and restricts the placement platform 901. The upper surface of the guide rail 7 is provided with anti-slip texture. Bolt 2 11 is threadedly connected to the moving platform 8. The bottom surface of bolt 2 11 contacts the upper surface of the guide rail 7. After bolt 2 11 is tightened, it can effectively prevent the moving platform 8 from moving.

[0021] Because the dimensions of the speaker grille decorative ring may vary during production, a corresponding mounting base 907 is customized based on the dimensions of the produced speaker grille decorative ring to accommodate this variation. This allows the mounting base 907 to be installed on the mounting platform 901 using bolts 908, ensuring it fits snugly against the outer wall of the speaker grille decorative ring and is placed stably. Pressure is applied and restrained by the pressure application part 906. The mounting platform 901 has multiple through holes for the bolts 908 to pass through, and also has a strip hole for the positional movement of the pressure application part 906. This facilitates the replacement of the mounting base 907 and appropriate adjustments to support speaker grille decorative rings of corresponding sizes.

[0022] The speaker grille decorative ring needs to be stably placed and supported. Therefore, it is preferable to have four placement seats 907, which are arranged concentrically with the vertical central axis of the placement platform 901 as the center. Each placement seat 907 is provided with two pressure parts 906. A pressure plate is fixedly provided at the top of the pressure part 906. After the pressure part 906 moves downward, it can apply pressure to the decorative ring through the pressure plate.

[0023] In order to allow the placement platform 901 to rotate smoothly and ensure that the pressure application part 906 can move downward synchronously to apply pressure to the speaker grille decorative ring, the following design is made: the lower end of the rotating platform 902 is rotatably connected to the moving platform 8, and a longitudinal groove is provided at its upper end. The connecting arm at the inner ring of the connecting part 904 can move up and down along the longitudinal groove of the rotating platform 902. The width of the connecting arm at the inner ring of the connecting part 904 is adapted to the width of the longitudinal groove of the rotating platform 902, so that the connection between the connecting part 904 and the rotating platform 902 is stable.

[0024] The drilling mechanism includes an electric cylinder 2, a fixed column 3, a mounting plate 4, and a drilling machine 5. The electric cylinder 2 is installed on the top of the workbench 1. The mounting plate 4 is fixedly installed at the output end of the electric cylinder 2 and moves along the guide rail on the inner wall of the workbench 1. The drilling machine 5 is installed at the bottom of the mounting plate 4 through a bracket. There are two fixed columns 3, which pass through the top plate of the workbench 1 and are fixed to the upper surface of the mounting plate 4. During the drilling operation, the electric cylinder 2 can be driven to push the mounting plate 4 downward along the guide rails on both sides of the inner wall of the workbench 1, and push the drilling machine 5 downward synchronously. The drilling machine 5 drills holes in the speaker grille decorative ring.

[0025] The implementation principle of the speaker grille decorative ring drilling device in this application embodiment is as follows: Beforehand, according to the size of the decorative ring, place four appropriately sized placement seats 907 in the corresponding positions on the placement platform 901. Then, connect the placement seats 907 to the corresponding threaded holes on 901 by bolts 908 through the ear plates at the lower end of the placement seats 907, locking the placement seats 907 onto the placement platform 901. Next, extend the pressure part 906 through the placement seats 907 downwards to the bottom of the placement platform 901. Tighten the fixing rod 905 through the bottom of the pressure part 906 and the threaded connection part 904. At this point, the decorative ring can be installed. Figure 5 The speaker cover shown fits snugly on four mounting seats 907 for support. The drive cylinder 909 pulls the connecting part 904 downward. The connecting part 904 can drive the pressure part 906 to move downward through the fixing rod 905, and then the upper end plate of the pressure part 906 applies pressure from above to limit the decorative ring. Move the moving stage 8 along the guide rail 7 and the fixed seat 6 so that the edge of the decorative ring is moved to the position directly below the drill bit of the drilling machine 5. Adjust the position of the decorative ring in this way, and then turn the bolt 11 and tighten it (the bolt 11 can be turned with the help of an external hex wrench) to lock the moving stage 8 on the guide rail 7. Then push the limiting block 1002 to slide along the slide 1001 so that a fixed shaft 903 is inserted into the limiting block 1002. Insert the limiting shaft 1003 vertically into the limiting block 1002 and restrict the rotation of the placement stage 901 through the fixed shaft 903. During the drilling, in order to ensure the stability of the operation of the decorative ring during long-term drilling, the staff can hold the two fixed shafts 903 at both sides of the limiting component 10 while observing the drilling. Then, the drilling machine 5 can be started and the electric cylinder 2 can be driven to push the mounting plate 4 down along the guide rails on both sides of the workbench 1. The drilling machine 5 can then drill holes in the decorative ring. (Since the decorative ring requires eight holes of two different diameters, and the two diameters are set at equal intervals, one type of hole can be drilled first. After all the decorative rings have been drilled, the drill bit can be changed to drill the other type of hole.) After drilling one hole on the decorative ring, remove the limiting shaft 1003, move the limiting block 1002, rotate the placement platform 901 ninety degrees, move the limiting block 1002 again, insert the limiting shaft 1003 into the limiting block 1002, and limit the fixed shaft 903 at that position. In this way, drill holes in the decorative ring one by one.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
