With the development of the automotive industry and the widespread use of engineering plastics, car bumpers, as a crucial safety device, have undergone significant innovation. Currently, in addition to maintaining their original protective functions, front and rear bumpers must also strive for harmony and unity with the vehicle's design, and achieve lightweight construction. During the production process, punching fixtures are often used to fix the bumper in place, and then punching equipment is used to punch holes in the bumper.

[0003] In the prior art, Chinese patent CN220461914U discloses a punching fixture for automobile bumpers, including a worktable. Extended platforms are fixedly connected to both side walls of the worktable, and a fixed support is fixedly connected to the top of the extended platforms. The top of the fixed support is fixedly connected to the bottom of one end of a top fixed plate. A first electric telescopic rod is installed through the center of the top fixed plate, and a connector is fixedly connected to the bottom of the first electric telescopic rod. The connector is detachably installed inside a connecting groove, which is fixedly connected to the top of a processing module. A punching machine is installed at the top of the processing module, and an easily detachable punching head is detachably installed at one end of the punching machine that passes through the processing module.

[0004] However, the car bumper punching fixture provided in the above technical solution still has many shortcomings in actual use.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] Please see Figure 1-5 This utility model provides an embodiment of a car bumper punching fixture, including a mounting plate 1. Multiple positioning holes 18 are provided on the outer side of the mounting plate 1. A soft rubber pad 19 is fixedly connected to the bottom of the mounting plate 1. The multiple positioning holes 18 are evenly distributed in a ring about the vertical center line of the mounting plate 1. The top surface of the soft rubber pad 19 is in contact with the bottom surface of the mounting plate 1. Through the cooperation of the positioning holes 18 and external bolts, the mounting plate 1 can be fixed to the external water surface, completing the installation of this device. The soft rubber pad 19 prevents wear between the mounting plate 1 and the external horizontal surface.

[0028] In this embodiment, a ring platform 2 is fixedly connected to the top of the mounting plate 1. A liftable placement platform 3 is provided at the center of the ring platform 2. The vertical center line of the placement platform 3 coincides with the vertical center line of the ring platform 2. A lifting rod 17 is fixedly connected to the bottom of the placement platform 3. The bottom end of the lifting rod 17 is fixedly connected to the top surface of the mounting plate 1. The inner dimension of the ring platform 2 matches the outer dimension of the placement platform 3. A car bumper that needs to be punched can be placed on the placement platform 3. The height of the placement platform 3 and the car bumper can be adjusted by using the lifting rod 17.

[0029] In this embodiment, an annular groove 4 is provided on the top of the ring platform 2. Multiple sliding columns 5 are slidably connected inside the annular groove 4. Locking rings 6 are threadedly connected to the outer side of the sliding columns 5. The locking rings 6 have a plum blossom-shaped structure. The central axis of the locking rings 6 coincides with the central axis of the sliding columns 5. An adjusting frame 13 is fixedly connected to the top of the sliding columns 5. An arc-shaped rod 14 is provided in the middle of the adjusting frame 13. The adjusting frame 13 and the arc-shaped rod 14 are connected by a locking bolt 15. A locking nut 16 is threadedly connected to the end of the locking bolt 15. The arc-shaped rod 14 is fixedly connected to the electric slide rail 7. A slide table 8 is slidably connected to the inner side of the electric slide rail 7. An electric push rod 9 is fixedly connected to the side of the slide table 8 away from the electric slide rail 7. A support plate 10 is fixedly connected to the end of the electric push rod 9. A threaded rod 11 is connected to the upper threaded connection, and a pressing block 12 is fixedly connected to the end of the threaded rod 11. By rotating the threaded rod 11 and using it in conjunction with the support plate 10, multiple pressing blocks 12 can be pressed against the car bumper to complete the fixation of the car bumper. This facilitates punching holes in the car bumper. Loosening the locking nut 16, in conjunction with the locking bolt 15 and the adjusting bracket 13, allows the tilt angle of the arc rod 14 to be adjusted. By using the electric slide rail 7 and the slide table 8, the position of the pressing block 12 on the arc rod 14 can be adjusted. The distance between the pressing block 12 and the arc rod 14 can be adjusted by the electric push rod 9, thereby facilitating the adjustment of the pressing position and making it convenient to fix the car bumper at different positions, thus improving the clamping and fixing effect.

[0030] Working principle: When using this device, the mounting plate 1 is first fixed to the external water surface by using the positioning hole 18 and the external bolts, thus completing the installation of the device. The soft rubber pad 19 prevents wear between the mounting plate 1 and the external water surface. The car bumper that needs to be punched can be placed on the placement platform 3. The height of the placement platform 3 and the car bumper can be adjusted by using the lifting rod 17. By rotating the threaded rod 11 and using it in conjunction with the support plate 10, multiple pressing blocks 12 can be pressed against the car bumper. This completes the fixation of the car bumper, facilitating punching holes in the bumper. Loosening the locking nut 16, in conjunction with the locking bolt 15 and the adjusting bracket 13, allows for adjustment of the tilt angle of the arc rod 14. Utilizing the electric slide rail 7 and the slide table 8, the position of the pressure block 12 on the arc rod 14 can be adjusted. The distance between the pressure block 12 and the arc rod 14 can be adjusted via the electric push rod 9, thus facilitating the adjustment of the pressure position and enabling convenient fixation of the car bumper at different locations, improving the clamping and fixing effect.

[0031] By using the annular groove 4 on the ring platform 2 in conjunction with the sliding column 5, the position of the adjustable arc rod 14 can be adjusted. By tightening the locking ring 6, the sliding column 5 can be fixed at any position in the annular groove 4, making it easy to move the arc rod 14 to any direction of the car bumper. This facilitates the fixing of car bumpers of different specifications and improves the applicability of the device.
