Abstract
Description
Technical Field
[0001] This utility model relates to the field of bumper welding, and in particular to a car bumper bracket that is easy to weld. Background Technology
[0002] Car bumpers not only serve a decorative purpose but also absorb and mitigate external impacts, providing protection for the front and rear of the vehicle. They are crucial safety components in automobile manufacturing. During bumper welding, bumper brackets are required to secure the bumper. However, existing technologies present the following technical problems:
[0003] 1. Inconvenient adjustment: Traditional brackets are mostly fixed in height or rely on motor / cylinder adjustment, which are complex in structure and take up a lot of space, making it difficult to adapt to the welding requirements of bumpers of different car models;
[0004] 2. Easily damaged surfaces: Hard clamping parts can easily scratch the bumper coating, leading to increased rework rates;
[0005] 3. High cost: Automated control mechanisms require additional energy and maintenance costs, making them uneconomical;
[0006] 4. Lack of flipping components: During the welding process of bumper brackets, multiple welding points are often required, which necessitates flipping the bumper during welding. However, most welding brackets lack flipping components, and in actual operation, they rely on manual flipping, which is inefficient. Summary of the Invention

[0011] The height adjustment mechanism installed on the bracket includes a large gear, a rotating shaft, and a handle. The rotating shaft and the large gear are concentric circles and are embedded inside the large gear. The handle is sleeved on the outside of the rotating shaft through a bearing.
[0012] The flipping assembly includes a rotating disk and a flipping handle; the large gear on the rotating disk is a concentric circle and is rotatably connected to the large gear through a bearing; the rotating shaft passes through the rotating disk and is fixedly connected to it.
[0013] Connecting rods are fixedly connected to both sides of the clamp, and the connecting rods extend to both sides of the clamp and are fixedly connected to the rotating shaft located in the height adjustment mechanism on both sides.
[0014] Preferably, the bracket is provided with a moving track and a fixed track within a cross-shaped cavity, and the large gear is meshed with the moving track and the fixed track respectively.
[0015] Preferably, the rotating disk is provided with multiple positioning holes.
[0016] Preferably, the flip handle is fixedly connected to the upper end of the handle and engages with the positioning hole.

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1
[0031] An easy-to-weld car bumper bracket includes a base 1 and a clamp 2, and further includes:
[0032] The bracket 3 is symmetrically and vertically fixed to both sides of the base 1. The bracket 3 is a hollow structure with a cross-shaped cavity inside.
[0033] The height adjustment mechanism 4, which is set on the bracket 3, includes a large gear 41, a rotating shaft 42 and a handle 44. The rotating shaft 42 and the large gear 41 are concentric circles and are embedded in the large gear 41. The handle 44 is sleeved on the outside of the rotating shaft 42 through a bearing.
[0034] The flipping assembly 8 includes a rotating disk 81 and a flipping handle 82; the large gear 41 of the rotating disk 81 is a concentric circle and is rotatably connected to the large gear 41 through a bearing; the rotating shaft 42 passes through the rotating disk 81 and is fixedly connected to it.
[0035] Connecting rods 5 are fixedly connected to both sides of the clamp 2. The connecting rods 5 extend to both sides of the clamp 2 and are fixedly connected to the rotating shaft 42 located in the height adjustment mechanism 4 on both sides.
[0036] Preferably, the bracket 3 is provided with a moving track 6 and a fixed track 7 in a cross-shaped cavity, and the large gear 41 is meshed with the moving track 6 and the fixed track 7 respectively.
[0037] Preferably, the rotating disk 81 is provided with a plurality of positioning holes 83.
[0038] Preferably, the flip handle 82 is fixedly connected to the upper end of the handle 44 and engages with the positioning hole 83.
[0039] Preferably, the clamp 2 has a V-shaped structure and a buffer pad 21 is provided on its contact surface.
[0040] Preferably, it also includes a locating pin and multiple through holes (not shown in the figure), the locating pin can pass through the through holes and engage with the toothed slots of the moving track 6.
[0041] The positioning pin and the limiting mechanism with multiple through holes are common positioning methods in the prior art, and will not be described in detail in this utility model.
[0042] When this utility model is in use, the clamp 2 clamps the workpiece, and the operator holds the handle 44 and moves it up along the bracket 3 until the appropriate processing height is reached. The longitudinal limit is completed by locking the positioning component.
[0043] When it is necessary to flip the bumper bracket or adjust the welding angle, the operator holds the flip handle 82 and pulls it outward to pull the flip handle 82 out of the positioning hole 83. Rotating the flip handle 82 causes the rotating shaft 42 to rotate, which in turn causes the connecting rod 5 to rotate, thereby achieving the flipping. After flipping to the appropriate angle, the flip handle 82 is pushed inward into the positioning hole 83 on the rotating disk 81 to achieve angle limiting.
[0044] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
