[0027] Please refer to Figures 1-5 The outer cabinet plate punching device includes a workbench 1; it also includes a support column 2 fixedly connected to the lower end of the workbench 1, a first telescopic cylinder 301 fixedly connected to the lower end of the workbench 1, a first toothed plate 302 fixedly connected to the output end of the first telescopic cylinder 301, a first gear 303 meshing with one side of the first toothed plate 302, a second toothed plate 304 meshing with the other side of the first gear 303, a first connecting plate 305 fixedly connected to the second toothed plate 304, a second connecting plate 306 fixedly connected to one side of the first toothed plate 302, a connecting block 307 fixedly connected to the upper end of both the first connecting plate 305 and the second connecting plate 306, a fixing plate 308 fixedly connected to the upper end of the connecting block 307, a first threaded rod 309 threadedly connected to the upper end of the fixing plate 308, a knob 310 fixedly connected to the upper end of the first threaded rod 309, a pressure plate 311 fixedly connected to the lower end of the knob 310, and a punching assembly installed on the upper end of the workbench 1.

[0028] In a preferred embodiment of this invention, after the workpiece is placed in a suitable position on the worktable 1, the first telescopic cylinder 301 is activated, and its output end pushes the first toothed plate 302 to move. The linear motion of the first toothed plate 302 is converted into the rotational motion of the first gear 303 through meshing with the first gear 303. The rotation of the first gear 303 then meshes with the second toothed plate 304, causing the second toothed plate 304 to perform a linear motion in the opposite direction to that of the first toothed plate 302. The first toothed plate 302 and the second toothed plate 304 respectively drive the second connecting plate 306 and the first connecting plate 305 to move, thereby causing the two connecting blocks 307 and the fixing plate 308 at their upper ends to move towards or away from each other, adjusting the fixing plate 308 to a suitable position. By rotating the knob 310, the first threaded rod 309 moves downward in the threaded hole of the fixing plate 308, driving the pressure plate 311 to descend until the pressure plate 311 tightly presses the workpiece, thereby fixing the workpiece and preventing it from moving during the punching process, ensuring processing accuracy, and enabling the fixing of plates of different specifications.

[0029] In a preferred embodiment of this utility model, two sets of the first telescopic cylinder 301, the first toothed plate 302, the first gear 303, and the second toothed plate 304 are provided. The two sets of the first telescopic cylinder 301, the first toothed plate 302, the first gear 303, and the second toothed plate 304 are symmetrically arranged at the lower end of the worktable 1. The two symmetrically arranged transmission structures can simultaneously apply pressure from both sides of the workpiece. When the pressure plate 311 descends to clamp the workpiece, it ensures that the workpiece receives a uniform clamping force, preventing tilting, displacement, or deformation of the workpiece during processing due to unilateral force.

[0030] In a preferred embodiment of this utility model, a groove is provided on the second connecting plate 306, and the second toothed plate 304 penetrates the second connecting plate 306 through the groove, ensuring that the second toothed plate 304 can smoothly perform linear reciprocating motion under the drive of the telescopic cylinder, and will not collide with the second connecting plate 306 due to insufficient space, thus ensuring the stability and reliability of the equipment operation.

[0031] In a preferred embodiment of this utility model, a groove 2 is provided on the workbench 1, and the connecting block 307 is slidably connected to the inner side of the workbench 1 through the groove 2, thereby effectively guiding the connecting block 307; at the same time, the boundary of the groove 2 restricts the range of motion of the connecting block 307, preventing it from deviating or leaving the predetermined position, thus achieving a good limiting effect.

[0032] In a preferred embodiment of this utility model, multiple sets of the first threaded rod 309, the knob 310, and the pressure plate 311 are provided. Multiple sets of the first threaded rod 309, the knob 310, and the pressure plate 311 are arranged in a linear array on the fixing plate 308, which can apply stable and balanced pressure to the plate from multiple points of action, thereby significantly enhancing the fixing effect on the plate and ensuring that the plate is accurately positioned and stable during processing or assembly.

[0033] In a preferred embodiment of this utility model, the punching assembly includes a first guide rail 401 fixedly connected to the upper end of the workbench 1, a third toothed plate 402 fixedly connected to one side of the workbench 1, a first slide 403 slidably connected to the outside of the first guide rail 401, a mounting bracket 404 fixedly connected to the first slide 403, a self-locking motor 405 fixedly connected to the first slide 403, a second gear 406 fixedly connected to the output end of the self-locking motor 405, a second slide rail 407 fixedly connected to the mounting bracket 404, a drive motor 408 fixedly connected to one side of the second slide rail 407, a second threaded rod 409 fixedly connected to the output end of the drive motor 408, a second slide 410 threadedly connected to the outside of the second threaded rod 409, a second telescopic cylinder 411 fixedly connected to the lower end of the second slide 410, and a punching device body 412 fixedly connected to the output end of the second telescopic cylinder 411. The second gear 406 and... When the third toothed plate 402 engages, and the self-locking motor 405 starts, its output drives the second gear 406 to rotate. The second gear 406 engages with the third toothed plate 402 fixed on one side of the workbench 1, converting the rotational motion into linear motion. This drives the first slide 403 to slide horizontally along the first guide rail 401. When the first slide 403 moves, the mounting bracket 404 fixed on it moves synchronously, thereby adjusting the lateral position of the punching device body 412. After the drive motor 408 starts, its output drives the second threaded rod 409 to rotate. The second threaded rod 409 is threadedly connected to the second slide 410, converting the rotational motion into linear motion. This drives the second slide 410 to slide vertically along the second slide rail 407. When the second slide 410 moves, the second telescopic cylinder 411 fixed at its lower end and the punching device body 412 move synchronously, adjusting the longitudinal position of the punching device body 412, thereby achieving punching at different positions on the plate.

[0034] In a preferred embodiment of this utility model, the second slide table 410 is provided with a groove three, and the second slide table 410 is slidably connected to the outside of the second slide rail 407 through the groove three, so that when the second slide table 410 moves along the second slide rail 407, it can run strictly according to the predetermined trajectory, effectively playing a guiding role; at the same time, the cooperation between the groove three and the second slide rail 407 also restricts the displacement of the second slide table 410 in the non-movement direction, thereby achieving a good limiting effect.

[0035] During operation, after the workpiece is placed in a suitable position on the worktable 1, the first telescopic cylinder 301 is activated, and its output end pushes the first toothed plate 302 to move. The linear motion of the first toothed plate 302 is converted into the rotational motion of the first gear 303 through meshing with the first gear 303. The rotation of the first gear 303 then meshes with the second toothed plate 304, causing the second toothed plate 304 to perform a linear motion in the opposite direction to that of the first toothed plate 302. The first toothed plate 302 and the second toothed plate 304 respectively drive the second connecting plate 306 and the first connecting plate 305 to move, thereby causing the two connecting blocks 307 and the fixing plate 308 at their upper ends to move towards or away from each other, adjusting the fixing plate 308 to a suitable position. By rotating the knob 310, the first threaded rod 309 moves downward in the threaded hole of the fixing plate 308, driving the pressure plate 311 to descend until the pressure plate 311 tightly presses the workpiece, thus fixing the workpiece and preventing it from moving during punching, ensuring processing accuracy. It can fix plates of different specifications. After the self-locking motor 405 starts, its output end drives the second gear 406 to rotate. The second gear 406 and the third toothed plate 404 fixed on one side of the worktable 1 rotate. 2. Engagement converts rotational motion into linear motion, driving the first slide 403 to slide horizontally along the first guide rail 401. When the first slide 403 moves, the mounting bracket 404 fixed on it moves synchronously, thereby adjusting the lateral position of the punching device body 412. After the drive motor 408 starts, its output end drives the second threaded rod 409 to rotate. The second threaded rod 409 is threadedly connected to the second slide 410, converting rotational motion into linear motion, driving the second slide 410 to slide vertically along the second slide rail 407. When the second slide 410 moves, the second telescopic cylinder 411 fixed at its lower end and the punching device body 412 move synchronously, adjusting the longitudinal position of the punching device body 412, thereby realizing punching at different positions of the plate.

[0037] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
