[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0025] Embodiment 1

[0026] Referring to Figure 1 , this is the first embodiment of the present utility model. This embodiment provides a positioning and punching device for the bottom plate sheet metal, including

[0027] A bearing mechanism 100, including a fixing plate 101, and a support platform 102 is fixedly connected to the top surface of the fixing plate 101;

[0028] Among them, the fixing plate 101 is used to support the support platform 102, so that the support platform 102 supports the sheet metal T.

[0029] A punching mechanism 200, including a punching machine 201 fixedly arranged on one side of the fixing plate 101, and a control panel 202 is fixedly installed on one side surface of the punching machine 201;

[0030] Among them, the operator can adjust the punching strength and speed of the punching machine 201 through the control panel 202.

[0031] The positioning mechanism 300 includes a fixing frame 301 fixedly connected to the top surface of the fixing plate 101, and a limiting plate 302 fixedly installed on the top surface of the fixing frame 301.

[0032] Among them, the fixing frame 301 is used to support the limiting plate 302, the sheet metal T is slidably connected to the inner wall of the limiting plate 302, and the limiting plate 302 is used to limit the sheet metal T.

[0033] Specifically, a hydraulic cylinder 203 is adaptively installed on the top surface of the punching machine 201. The output end of the hydraulic cylinder 203 penetrates to the other surface of the punching machine 201 and is fixedly connected with a connecting block 204.

[0034] Among them, when the output end of the hydraulic cylinder 203 extends, it can drive the connecting block 204 to move downward.

[0035] Furthermore, the punching mechanism 200 further includes a punch 205 fixedly connected to the other surface of the connecting block 204, and a waste outlet 206 opened on one surface of the fixing frame 301. The waste outlet 206 communicates with the other surface of the fixing frame 301.

[0036] Among them, when the connecting block 204 moves downward, it can drive the punch 205 to move synchronously, so that the punch 205 punches the sheet metal T, and the waste generated after punching the sheet metal T is discharged through the waste outlet 206.

[0037] During use, insert the sheet metal T into the inner wall of the limiting plate 302. The operator turns on the punching machine 201 through the control panel 202 and adjusts the punching strength and speed of the punching machine 201, so that the output end of the hydraulic cylinder 203 reciprocates. When the output end of the hydraulic cylinder 203 extends, it drives the connecting block 204 to move downward, and the connecting block 204 drives the punch 205 to punch the sheet metal T. The waste generated after punching the sheet metal T is discharged through the waste outlet 206, avoiding waste accumulation on the inner wall of the limiting plate 302 and causing adverse effects on the sheet metal T.

[0038] In summary, automated punching can significantly accelerate the punching speed, reduce the time of manual intervention, thereby improving the overall production efficiency. The automatic waste discharging function greatly reduces the time of stopping the machine to clean the waste, enabling the machine to run continuously and further improving the production efficiency.

[0039] Embodiment 2

[0040] Refer to Figures 1 to 4 , this is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a positioning mechanism 300 that can automatically move the sheet metal T to the next punching position and position it by using the mechanical energy during punching the sheet metal T.

[0041] Specifically, an inclined block 303 is fixedly installed on one side surface of the fixing frame 301, a first fixing block 304 is fixedly connected to one side surface of the connecting block 204, and a rotating column 305 is fixedly installed on one side surface of the first fixing block 304.

[0042] Among them, the fixing frame 301 is used to prevent the position of the inclined block 303 from shifting, and when the connecting block 204 moves downward, it can drive the first fixing block 304 and the rotating column 305 to move synchronously.

[0043] Furthermore, a rotating rod 306 is rotatably connected to the surface of the rotating column 305, and a positioning column 307 and a first spring 308 are fixedly installed on one side surface of the connecting block 204.

[0044] Among them, when the rotating column 305 moves downward, it can drive the rotating rod 306 to pass through the opening on the surface of the sheet metal T and contact the inclined block 303. The inclined block 303 squeezes the rotating rod 306, causing the rotating rod 306 to rotate while driving the sheet metal T to move and applying a pulling force to the first spring 308.

[0045] Preferably, a second fixing block 309 is fixedly connected to one side surface of the support platform 102, and a second spring 310 is fixedly installed on the top surface of the second fixing block 309.

[0046] Among them, the second fixing block 309 is used to support the second spring 310.

[0047] It should be noted that the positioning mechanism 300 further includes a movable plate 311 hinged to the inner wall surface of the support platform 102. A special-shaped block 312 is fixedly installed on the top surface of the movable plate 311, and the bottom surface of the movable plate 311 is fixedly connected to the other end of the second spring 310.

[0048] Among them, the second spring 310 is used to reset the movable plate 311 and prevent the movable plate 311 from flipping due to the reaction force of the second spring 310. One side surface of the special-shaped block 312 is an inclined surface, and the other side surface is a flat surface.

[0049] During use, when the connecting block 204 moves downward, it drives the first fixed block 304 and the rotating column 305 to move synchronously. The rotating column 305 drives the rotating rod 306 to pass through the opening on the surface of the sheet metal T and contact the inclined block 303. Then, the inclined block 303 squeezes the rotating rod 306, causing the rotating rod 306 to rotate while driving the sheet metal T to move and applying a tensile force to the first spring 308. At the same time, through the movement of the sheet metal T, the inclined surface of the special-shaped block 312 is squeezed, causing the special-shaped block 312 to squeeze the movable plate 311, and then applying a pressure to the second spring 310 through the movable plate 311. When the next punching hole on the surface of the sheet metal T moves above the special-shaped block 312, the movable plate 311 is reset by the reaction force of the second spring 310, and the movable plate 311 moves the special-shaped block 312 into the next punching hole on the surface of the sheet metal T. When the connecting block 204 drives the rotating rod 306 to move upward, the sheet metal T is limited by the plane of the special-shaped block 312 to prevent the sheet metal T from being pulled back by the rotating rod 306. When the rotating rod 306 moves to a position where it is disengaged from the inclined block 303, it is pulled back by the reaction force of the first spring 308, and the rotating rod 306 stays at the initial position through the limitation of the positioning column 307, facilitating the next positioning punching operation.

[0050] In summary, by utilizing the mechanical energy during punching of the sheet metal T, the sheet metal T can be quickly moved to the next punching position and positioned, reducing the use of additional power sources, thereby reducing energy consumption. It can not only reduce the preparation time for manually moving and fixing the sheet metal T, but also maintain the consistency of the punching position and size each time.
