Description

Technical Field

[0001] This utility model relates to the field of mechanical processing positioning technology, specifically a perforated aluminum single-panel punching positioning device. Background Technology

[0002] In architectural decoration and industrial manufacturing, perforated aluminum panels are widely used due to their advantages such as lightweight, aesthetics, and ventilation. The quality of the perforation process directly affects the structural strength, decorative effect, and acoustic performance of the product. However, existing aluminum panel perforation positioning technology has the following significant problems: Traditional manual positioning methods rely on worker experience, using tools such as measuring tapes and squares to measure and mark lines. Positioning errors generally exceed ±0.5mm, leading to deviations in punching positions and uneven arrangement, which seriously affects product quality. Moreover, manual operation is inefficient and cannot meet the needs of large-scale production.

[0003] Some automated positioning equipment uses a rigid clamping structure and lacks a pressure feedback mechanism. During the clamping process, excessive pressure can easily cause the perforated aluminum panel to deform, especially for thin panels with a thickness of less than 2mm, resulting in a scrap rate of over 15%.

[0004] Therefore, those skilled in the art have provided a perforated aluminum panel punching and positioning device to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Reference Figures 1-5 This embodiment provides a perforated aluminum single panel punching and positioning device, including a punching template 1. The punching template 1 has side clamping plates 3 on both sides of its upper end. A gear 16 is rotatably installed at the center of the bottom of the punching template 1. A rack 13 is meshed on both sides of the gear 16. The rack 13 is slidably connected to the bottom of the punching template 1. One end of the rack 13 is connected to a connecting plate 11 through a connecting rod 12. Two vertical plates 10 are fixedly connected to the upper end of the connecting plate 11. A guide rod 9 is connected to the front end of the vertical plate 10. A guide block 8 fixed to the punching template 1 is sleeved on the guide rod 9. A guide sleeve 5 is connected to the front end of the guide rod 9. A horizontal plate 6 for fixing a pressure sensor 7 is provided between the guide sleeves 5. A compression spring 21 and a guide post 4 fixed to the side clamping plates 3 are provided inside the guide sleeve 5. Example

[0023] Reference Figures 1-5This embodiment is based on the previous embodiment, but differs from the previous embodiment in that the bottom of the punching template 1 is equipped with a drive motor 15 via a bracket 14, the output shaft of the drive motor 15 is connected to a gear 16 via a coupling, the drive motor 15 and the pressure sensor 7 are electrically connected to an external control system, the pressure sensor 7 monitors the clamping force of the side clamping plate 3 on the aluminum single panel in real time, and when the pressure exceeds a preset threshold, the control system automatically adjusts the speed of the drive motor 15 to prevent deformation of the aluminum single panel.

[0024] Furthermore, the bottom rear end of the punching template 1 is provided with a support plate 17, the upper end of the support plate 17 is connected to a column 18, the column 18 is threadedly connected to a screw 19, the front end of the screw 19 is rotatably connected to a reference plate 2, and the rear end of the screw 19 is connected to a rotating wheel 20. The reference plate 2 is in movable contact with the upper surface of the punching template 1. The column 18 is provided with an internal thread that matches the screw 19. By rotating the rotating wheel 20 to drive the screw 19, the front and rear position of the reference plate 2 can be adjusted to meet the positioning requirements of aluminum single panels of different sizes.

[0025] Furthermore, the guide block 8 is provided with a sliding groove adapted to the guide rod 9 to limit the sliding direction of the guide rod 9 and ensure the linear accuracy of the side clamping plate 3 movement. One end of the compression spring 21 is fixed to the inner wall of the guide sleeve 5 and the other end is fixed to the guide post 4 to provide elastic clamping force for the side clamping plate 3 and buffer the impact force during the clamping process. The anti-slip rubber layer provided on the inner side of the side clamping plate 3 increases the friction with the aluminum single panel, prevents the aluminum single panel from sliding during the clamping process, and protects the surface of the aluminum single panel from being scratched. Working principle: The operator rotates the rotating wheel 20, causing the screw 19 to move back and forth along the threaded structure of the column 18. Since the front end of the screw 19 is connected to the reference plate 2 through a rotating joint, the reference plate 2 moves synchronously with the screw 19 until it reaches the reference point corresponding to the position to be punched on the aluminum panel. At this time, the reference plate 2 maintains parallel contact with the upper surface of the punching template 1, providing a precise lateral positioning reference for the aluminum panel. By adjusting the screw depth of the screw 19, the position of the reference plate 2 can be flexibly adjusted to adapt to perforated aluminum panels of different widths, achieving the versatility of the positioning device. Then, the drive motor 15 is started, and its output shaft drives the gear 16 to rotate through the coupling. Since the gear 16 meshes with the racks 13 on both sides, and the racks 13 are slidably connected to the bottom of the punching template 1, the rotation of the gear 16 drives the racks 13 on both sides to move in opposite or opposite linear motions. The racks 13 drive the connecting plate 11 to move synchronously through the connecting rod 12, and the vertical plate 10 on the connecting plate 11 pushes the guide rod 9 to slide linearly along the sliding groove of the guide block 8. The guide sleeve 5 and side clamping plate 3 at the front end of the guide rod 9 move accordingly, realizing the synchronous opening and closing action of the two side clamping plates 3. When the side clamping plate 3 contacts the edge of the aluminum single panel, as the drive motor 15 continues to run, the guide post 4 begins to compress the compression spring 21 inside the guide sleeve 5. The elastic force generated by the spring deformation is transmitted to the side clamping plate 3 through the guide post 4, forming a flexible clamping force on the aluminum single panel, avoiding damage to the panel caused by rigid contact. During the extrusion process, the back of the side clamping plate 3 gradually approaches and contacts the pressure sensor 7 on the horizontal plate 6. The pressure sensor 7 converts the real-time pressure value into an electrical signal and transmits it to the external control system. When the pressure reaches the preset threshold, the control system automatically adjusts the output power of the drive motor 15 or stops running, realizing closed-loop control. Under the stable pressure feedback from the pressure sensor 7, the side clamping plate 3 is tightly attached to the aluminum single panel through the anti-slip rubber layer, while the reference plate 2 provides lateral limit to ensure that the aluminum single panel does not shift during the punching process. It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
