[0003] When drilling automotive sealing strips, the sealing strip material, such as rubber or EPDM, is first cut into appropriate shapes and lengths. Then, the sealing strip is manually placed on the processing platform of the stamping and drilling device, and the sealing strip is drilled by multiple sets of drilling heads on the stamping device.

[0004] Considering that drilling holes in sealing strips of different specifications requires adjusting the spacing between multiple sets of drilling heads to accommodate the drilling operation, and that this adjustment is typically done by operators loosening locking nuts or bolts, adjusting the position of the drilling heads, and then re-fixing them to ensure the spacing between the multiple sets of drilling heads meets the requirements, this process is time-consuming. This is especially true when frequently changing the spacing of the drilling heads, which increases operating time and labor costs. Furthermore, the need for extended downtime during adjustments reduces production speed, and frequent adjustments negatively impact the overall efficiency of the production line, reducing output. Therefore, a drilling device for automotive sealing strip processing is proposed to address these issues. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 , Figure 3 - Figure 4This utility model provides an embodiment of a drilling device for processing automotive sealing strips, comprising a base 1. A telescopic motor 4 is fixedly connected to the top of the outer surface of the base 1, providing a fixed support for the telescopic motor 4. A movable plate 3 is fixedly connected to the bottom output shaft of the telescopic motor 4, enabling the telescopic motor 4 to drive the movable plate 3 to move vertically. A hinge assembly 13 is slidably connected to the inner surface of the movable plate 3, allowing the hinge assembly 13 to move laterally and extend along the inner surface of the movable plate 3. The left and right sides of the inner surface of the hinge assembly 13 are both rotatable and slidably connected to a rotating shaft B11, allowing the rotating shaft B11 to move along the hinge... The hinge assembly 13 has the effect of rotating its inner surface on the left and right sides, and when it extends or retracts, it can simultaneously drive the pivot B11 to move laterally. There are four sets of pivot B11, so that the four sets of pivot B11 on both sides of the hinge assembly 13 can simultaneously move towards the center of the hinge assembly 13 due to its extension or retraction. A punch head 7 is fixedly connected to the bottom end of the pivot B11, so that when the pivot B11 moves laterally, it can simultaneously drive the punch head 7 to move laterally. A pivot A10 is rotatably connected to the center of the inner surface of the hinge assembly 13, so that when the hinge assembly 13 extends or retracts, it can move along the pivot A10. To achieve an inward contraction effect, the outer surface of the rotating shaft A10 is fixedly connected to the middle of the inner surface of the moving plate 3. The middle of the inner surface of the moving plate 3 provides a fixed support for the rotating shaft A10. Five sets of punch heads 7 are provided, allowing four sets of punch heads 7 on either side of the moving plate 3 to simultaneously move towards the middle set of the moving plate 3 under the influence of the hinge assembly 13. This achieves the effect of simultaneously adjusting the spacing between multiple sets of punch heads 7. A hinge member 12 is hinged to the left side of the outer surface of the hinge assembly 13, allowing the hinge member 12 to simultaneously drive the hinge assembly 13 to perform a telescopic hinge effect when moving laterally. The inner surface of the hinge member 12... A threaded rod 6 is threadedly connected to the left side, allowing the threaded rod 6 to rotate along the left side of the inner surface of the hinge 12. Furthermore, when the threaded rod 6 moves laterally, it causes the hinge 12 to move as well. The left side of the outer surface of the threaded rod 6 is threadedly connected to the left side of the inner surface of the moving plate 3, allowing the threaded rod 6 to move laterally during rotation due to this connection. A rotating rudder is fixedly connected to the left side of the outer surface of the threaded rod 6, making rotation easier. The inner surface of the punch head 7 is equipped with a material ejector assembly, allowing any material blocking the punch head 7 to be ejected.

[0033] Reference Figure 3 - Figure 5The ejector assembly includes an ejector 16, a spring B18, a guide block 17, and a guide groove B15. The outer surface of the ejector 16 is elastically connected to the bottom end of the inner surface of the punch head 7 via the spring B18, allowing the ejector 16 to maintain a downward movement without external force. The guide block 17 is fixedly connected to the outer surface of the punch head 7, enabling the punch head 7 to move vertically and drive the guide block 17 to move together. The bottom end of the inner surface of the punch head 7 has a guide groove B15, allowing the guide block 17 to always move vertically along a designated position. The outer surface of the guide block 17 and the guide groove B15 are connected... The inner surface is slidably connected, allowing the ejector 16 to always move vertically along a designated position as the guide block 17 slides along the inner surface of the guide groove B15. The bottom end of the outer surface of the punch head 7 is elastically connected to the positioning frame 8 via a spring A9, so that the positioning frame 8 always moves downward without being affected by external forces. The outer surface of the punch head 7 is provided with a guide groove A14, so that the positioning frame 8 can always move vertically along the inner surface of the guide groove A14. The inner surface of the positioning frame 8 is slidably connected to the bottom end of the outer surface of the punch head 7, so that the positioning frame 8 can move vertically along the bottom end of the outer surface of the punch head 7.

[0034] Reference Figure 1 - Figure 3 A guide post 5 is fixedly connected to the top of the outer surface of the base 1, providing fixed support for the guide post 5. The rear end of the inner surface of the moving plate 3 is slidably connected to the outer surface of the guide post 5, so that the moving plate 3 can always maintain the effect of moving along the designated position when moving vertically due to the slidable connection with the outer surface of the guide post 5. A processing platform 2 is fixedly connected to the front end of the outer surface of the base 1, so that the sealing strip can be placed on the processing platform 2 and processed by the punching head 7. The top of the outer surface of the processing platform 2 has a through groove, and the bottom end of the outer surface of the punching head 7 penetrates and is slidably connected to the inner surface of the through groove, so that the punching head 7 can punch the sealing strip by penetrating the through groove. The bottom end of the outer surface of the positioning frame 8 is in contact with the top of the outer surface of the processing platform 2, so that the positioning frame 8 can contact the top of the sealing strip before the punching head 7 punches the sealing strip, thereby preventing the sealing strip from shifting when the punching head 7 punches the sealing strip.

[0035] Reference Figure 3 - Figure 5One end of spring A9 is fixedly connected to the outer surface of the punch head 7, and the other end of spring A9 is fixedly connected to the top of the outer surface of the positioning frame 8. This allows the positioning frame 8 to return to its original position downwards by the elastic force of spring A9 when it stops contacting the top of the processing platform 2. One end of spring B18 is fixedly connected to the inner surface of the punch head 7, and the other end of spring B18 is fixedly connected to the top of the outer surface of the ejector 16. This allows the ejector 16 to push out the blocked sealing strip material by the elastic force of spring B18 when the inside of the punch head 7 is blocked by the sealing strip material.

[0036] Working principle: When using the device, first manually place the sealing strip on the processing platform 2, then start the telescopic motor 4, which drives multiple sets of punch heads 7 on the moving plate 3 to move downwards simultaneously, so that multiple sets of punch heads 7 punch holes at the top of the sealing strip at the same time. When the punch head 7 contacts the top of the sealing strip, the positioning frame 8 will first contact the top of the sealing strip, squeezing and fixing the sealing strip in the designated position to prevent the punch head 7 from shifting when punching the sealing strip. Then the punch head 7 will penetrate the sealing strip and the through groove, thus achieving the effect of punching the sealing strip.

[0037] When it is necessary to adjust the spacing between the punch heads 7, first rotate the threaded rod 6 to make the hinge 12 move laterally. When the hinge 12 moves laterally, it will simultaneously cause the hinge assembly 13 to extend and retract laterally. When the hinge assembly 13 extends and retracts laterally, it will extend and retract around the pivot A10, and at the same time, it will cause the pivots B11 on both sides of the hinge assembly 13 to move closer to the pivot A10. Since the bottom end of the pivot B11 is fixedly connected to the top end of the punch head 7, the pivot B11 will move simultaneously when it moves, thereby achieving the effect of adjusting the spacing between multiple sets of punch heads 7 at the same time.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
