Description

Technical Field

[0001] This utility model relates to the field of bumper processing technology, specifically a rotatable bumper processing limiting device. Background Technology

[0002] Bumper processing refers to the manufacturing and finishing process of car bumpers. Typically, materials such as plastics and metals are first shaped into the basic form of the bumper using processes like injection molding and compression molding. Next, surface treatments such as sanding and painting are applied to improve the appearance and corrosion resistance. Afterward, assembly and adjustments may be performed, such as installing anti-collision beams and sensors, to ensure the bumper matches the car body and provides anti-collision and cushioning functions. The entire process must balance structural strength, safety, and aesthetics to meet automotive manufacturing standards and requirements.

[0003] The existing Chinese patent announcement number CN222244375U, entitled "A Rotatable Bumper Processing Limiting Device," explicitly states in its abstract that "This utility model applies to the field of automotive bumper processing technology, providing a rotatable bumper processing limiting device, comprising: a base, the base having a recessed cavity, and a rotating component installed in the cavity and on the upper end of the base; the rotating component, capable of driving the clamped bumper to rotate horizontally, the rotating component comprising..." During the clamping and fixing process of the bumper, the rotatable bumper processing limiting device can adjust the distance between two sets of clamping components according to the width of the bumper via a drive component. Then, the worker holds the bumper and places it within the clamping plate of the clamping component. At this time, an inductive switch can detect this and control the electromagnet to be energized, causing it to attract a magnetic block. During the attraction process, the pressure plate moves downward and the telescopic column and spring stretch, automatically clamping and fixing the bumper without manual operation. This not only ensures the stability of the bumper during processing but also improves processing efficiency.

[0004] However, in this technology, metal shavings, dust and other impurities are generated during the processing of the bumper. These impurities may enter the slide groove of the device and the screw inside the slide groove. Since they are inside, cleaning is inconvenient, which affects its normal operation and service life. Utility Model Content

[0005] The purpose of this utility model is to provide a rotatable limiting device for bumper processing, so as to solve the problem mentioned in the background art that metal chips, dust and other impurities are generated during the processing of bumpers, and these impurities may enter the slide groove of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotatable bumper processing limiting device includes a base and a rotating disk, with limiting components provided on both sides of the rotating disk;

[0008] The limiting component includes two mounting seats and two fixing frames. The inner side of the mounting seat is provided with a rectangular groove, and a gear is rotatably arranged above the rectangular groove. The outer side of the fixing frame is provided with a rectangular column.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figures 1-4 The present invention relates to a rotatable bumper processing limiting device, comprising a base 1 and a rotating disk 11. The base 1 is the bottom structure of the device, and the rotating disk 11 is the rotating structure. A motor 12 is provided inside the base 1. The drive shaft of the motor 12 is connected to the rotating disk 11, that is, the rotating disk 11 is driven by the motor 12 to rotate, thereby causing the bumper above the rotating disk 11 to rotate.

[0027] Limiting components are provided on both sides of the rotating disk 11. The limiting components include two mounting seats 13 and two fixing frames 2. The two mounting seats 13 are fixedly installed on both sides of the rotating disk 11. An electric telescopic rod 21 is provided on the top of the fixing frame 2. A fixing plate 22 is provided on the telescopic end of the electric telescopic rod 21. By installing the two sides of the bumper in the fixing frames 2 on both sides, the fixing plate 22 is pushed by the electric telescopic rod 21, thereby fixing the two sides of the bumper.

[0028] A rectangular groove 14 is provided on the inner side of the mounting base 13. A gear 3 is rotatably mounted above the rectangular groove 14. A rectangular column 23 is provided on the outer side of the fixing frame 2. The rectangular column 23 is slidably connected to the rectangular groove 14. A rack 24 is provided on the rectangular column 23. The gear 3 meshes with the rack 24. That is, by rotating the gear 3 on the outer side, the fixing frames 2 on both sides can slide inward and outward through gear transmission, thereby matching bumpers of different lengths.

[0029] Gear 3 has a hexagonal groove 31 inside, and a hexagonal prism 32 is slidably arranged inside the hexagonal groove 31. A retaining tooth 33 is arranged behind the hexagonal prism 32, and the retaining tooth 33 has the same number of teeth as gear 3. A tooth groove 34 is arranged on the rear side above the rectangular groove 14. The retaining tooth 33 is installed and removed in the tooth groove 34. The retaining tooth 33 is fully inserted into the tooth groove 34, and the arc of each tooth rotation corresponds to its insertion. A rotating plate 4 is rotatably arranged on the front side above the rectangular groove 14. A connecting block 42 is arranged in front of the hexagonal prism 32. A spring 41 is arranged behind the rotating plate 4. The connecting block 42 is connected in front of the spring 41, and a connecting rod 43 is arranged behind the connecting block 42. The connecting rod 43 passes through the inner side of the rotating plate 4 and is located in front of the outer side of the mounting base 13. The hexagonal column 32 can be pulled and rotated from the outside. Under normal circumstances, the spring 41 pushes the connecting block 42, causing the locking tooth 33 to be inserted into the tooth groove 34. By pulling the hexagonal column 32 from the outside through the connecting rod 43, the locking tooth 33 is disassembled in the tooth groove 34. At this time, the connecting rod 43 can be rotated, and the hexagonal column 32 and the gear 3 can be rotated at the same time. After the gear 3 has rotated, the locking tooth 33 can be inserted into the tooth groove 34 by releasing the connecting rod 43, thereby fixing the gear 3. Even if it cannot be inserted, it can be fixed by slightly rotating it again.

[0030] The working principle of this utility model is as follows: By installing the two sides of the bumper in the fixed brackets 2 on both sides, the fixed plate 22 is pushed by the electric telescopic rod 21 to fix the two sides of the bumper. The hexagonal column 32 is pulled on the outside by the connecting rod 43, so that the locking teeth 33 are disassembled in the tooth groove 34. At this time, the connecting rod 43 can be rotated, and the hexagonal column 32 and the gear 3 are rotated at the same time. Through gear transmission, the fixed brackets 2 on both sides can slide inward and outward to match bumpers of different lengths. After the gear 3 has rotated, the locking teeth 33 can be inserted into the tooth groove 34 by releasing the connecting rod 43, so as to fix the gear 3. Even if it cannot be inserted, it can be fixed by a slight rotation. The rotating disk 11 is driven by the motor 12 to rotate, so that the bumper above the rotating disk 11 rotates.
