Technical Field
[0001] This utility model belongs to the field of fixture and tooling technology, and in particular relates to a fixture and tooling for welding bumpers. Background Technology
[0002] Bumpers are safety devices that absorb and mitigate external impacts, protecting the front and rear of the vehicle. (See attached image) Figure 1 As shown, during the bumper manufacturing process, the bent bumper U-shaped tube 100 needs to be combined and welded with the bumper mounting lugs 200 to form a complete bumper. However, existing manufacturing techniques mostly involve clamping and fixing the bumper U-shaped tube 100 using a cylinder clamping mechanism, and then positioning and welding the bumper mounting lugs 200 onto the two threaded ends of the bumper U-shaped tube 100. During the welding process, the operator needs to hold the lugs by hand for positioning, which can easily lead to positioning deviations, resulting in poor operational stability and affecting the welding quality. Therefore, we propose a bumper welding fixture to solve the aforementioned problems. Utility Model Content
[0003] In view of this, in order to solve the problems of positioning deviation, poor stability of the welding process, and poor welding quality caused by traditional welding methods, this utility model provides a fixture for welding bumpers.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a fixture for welding bumpers, including a positioning seat, wherein the positioning seat is integrally formed by a base plate and a side plate, and the base plate and the side plate form an L-shaped seat body;

Each of the two second limiting blocks and the adjacent second protruding edge has a second positioning groove for positioning and locking the vertical section of the bumper U-shaped tube.
[0014] Furthermore, both locking rods include an integrally formed operating end and a threaded connection end. The outer diameter of the operating end is larger than the outer diameter of the threaded connection end. Two threaded holes that are threadedly connected to the threaded connection end are symmetrically opened on one side of the abutment plate.
[0015] Furthermore, the inner side of the side plate is provided with an inclined surface, forming an angle greater than 90° with the top surface of the bottom plate.
[0016] Furthermore, the top of the side plate is integrally provided with a flange extending upward toward the top of the bottom plate.
[0017] The embodiments of this utility model have the following beneficial effects:
[0018] This invention utilizes the cooperation of the first and second positioning grooves to stably position the bumper U-shaped tube onto the positioning seat. The locking and placing operation is simple and the positioning effect is excellent. The mounting lug is then positioned and aligned with the U-shaped tube, and the mounting lug is secured by the cooperation of the abutment plate and the locking rod, thus achieving a positioning connection between the U-shaped tube and the mounting lug.

[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0027] Example 1: Please refer to Figures 2-4 As shown, this embodiment provides a bumper welding fixture, including a positioning seat 1. The positioning seat 1 is integrally formed from a base plate 11 and a side plate 12, and the base plate 11 and the side plate 12 form an L-shaped seat. The base plate 11 is a rectangular plate, and the side plate 12 is a trapezoidal plate. Furthermore, the inner surface of the side plate 12 has an inclined surface, forming an angle greater than 90° with the top surface of the base plate 11. This angle is designed based on the angle between the horizontal and vertical sections of the bumper U-shaped tube 100, allowing the entire bumper U-shaped tube 100 to be better fitted and positioned with the positioning seat 1.
[0028] The base plate 11 has a first positioning component on its top for positioning the horizontal section of the bumper U-shaped tube 100. The first positioning component includes two first protruding edges 3 and two first limiting blocks 4. The two first protruding edges 3 are integrally formed on both sides of the top of the base plate 11. The two first limiting blocks 4 are symmetrically fixedly connected to the top of the base plate 11 and located between the two first protruding edges 3, and each of the two first limiting blocks 4 forms a first positioning groove 5 between itself and the adjacent first protruding edge 3. When positioning the bumper U-shaped tube 100 on the positioning seat 1, the horizontal section of the bumper U-shaped tube 100 is first placed from top to bottom into the two first positioning grooves 5, completing the initial positioning of the bumper U-shaped tube 100.
[0029] The inner side of the side plate 12 is provided with a second positioning component for positioning the vertical section of the bumper U-shaped tube 100. The second positioning component includes two second protruding edges 6 and two second limiting blocks 7. The two second protruding edges 6 are integrally formed on both sides of the inner side of the side plate 12. The two second limiting blocks 7 are symmetrically fixedly connected to the inner side of the side plate 12 and located between the two second protruding edges 6, and each of the two second limiting blocks 7 forms a second positioning groove 8 between itself and the adjacent second protruding edge 6. Since the side plate 12 is a trapezoidal plate with a short top edge and a long bottom edge, the second protruding edges 6 and the second limiting blocks 7 are both inclined, thus making the two second positioning grooves 8 also inclined grooves, which can adapt to the inclination of the vertical section of the bumper U-shaped tube 100. After positioning the horizontal section of the bumper U-shaped tube 100 within the first positioning groove 5, push the bumper U-shaped tube 100 towards the side panel 12, causing the vertical section to be positioned within the second positioning groove 8, and ensuring that the vertical section of the bumper U-shaped tube is in contact with the inner surface of the side panel 12, thus completing the positioning of the entire bumper U-shaped tube 100. Because the vertical section of the bumper U-shaped tube 100 is inclined, it is necessary to first position its horizontal section before horizontally pushing it to complete the entire positioning operation.
[0030] In one aspect of this embodiment, the top of the side plate 12 is integrally provided with a flange 13 extending upward toward the top of the bottom plate 11. By providing the flange 13, the top end of the vertical section of the bumper U-shaped tube 100 can be abutted and limited, making its positioning more stable during the welding process.
[0031] This invention can be used in the field of fixtures and tooling for bumper welding, and can also be applied to other fields.
[0032] Example 2: This example is a further improvement on the previous example: as follows Figures 2-4As shown, the fixture also includes a stop plate 2 fixedly connected to the side of the base plate 11 away from the side plate 12, and uses two locking rods 9 to complete the positioning connection between the bumper mounting lug 200 and the bumper U-shaped tube 100. Each locking rod 9 includes an integrally formed operating end 91 and a threaded connection end 92. The outer diameter of the operating end 91 is larger than the outer diameter of the threaded connection end 92, facilitating the abutment and limiting of the bumper mounting lug 200 through the operating end 91. One side of the stop plate 2 has symmetrically provided threaded holes 21 that are threaded to the threaded connection end 92. After positioning the bumper U-shaped tube 100 on the positioning seat 1, the bumper mounting lug 200 is then fitted onto the outer side of the backing plate 2, with the connecting holes of the bumper mounting lug 200 corresponding to the two welding ends of the bumper U-shaped tube 100. At this point, the positioning holes on the bumper mounting lug 200 correspond exactly to the two screw holes 21 on the backing plate 2. Then, the threaded connection end 92 of the locking rod 9 is passed through the positioning hole of the bumper mounting lug 200 and connected to the screw hole 21, thus completing the fixation of the bumper mounting lug 200 and completing the positioning connection between the bumper mounting lug 200 and the bumper U-shaped tube 100, facilitating subsequent welding work. After welding is completed, simply remove the locking rod 9 to pull the entire bumper outwards and remove it.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
