[0025] See also Figure 1-5The utility model provides a technical solution: a swing arm bushing mounting bracket of a nut welding box structure, comprising a swing arm bushing mounting bracket body 1, a subframe 2 and a swing arm 3, the swing arm bushing mounting bracket body 1 is integrally cast and die-cast, and the swing arm bushing mounting bracket body 1 is a U-shaped structure, the swing arm bushing mounting bracket body 1 of this structure is stable through the U-shaped structure, two swing arm bushing mounting bracket bodies 1 are a group, and each group of swing arm bushing mounting bracket bodies 1 is symmetrically matched, and the mounting part of the swing arm 3 is stuck between a group of swing arm bushing mounting bracket bodies 1, this structure uses a split swing arm bushing mounting bracket body 1, and the installation distance between the swing arm bushing mounting bracket bodies 1 can be adjusted as needed to adapt to the installation of the swing arm 3, the swing arm bushing mounting bracket The frame body 1 is arranged on the sub-frame 2, and the swing arm bushing mounting bracket body 1 is provided with an arc structure that engages with the sub-frame 2, and the swing arm bushing mounting bracket body 1 is welded and fixed to the sub-frame 2. This structure allows the swing arm bushing mounting bracket body 1 to fit the sub-frame 2 more closely, thereby ensuring the structural strength of the swing arm bushing mounting bracket body 1. A swing arm bushing mounting hole 101 is provided on the swing arm bushing mounting bracket body 1, and a nut welding box 4 is welded on one side of the swing arm bushing mounting bracket body 1. The nut welding box 4 is made of a cross-shaped structure by integral stamping, and a through hole 401 is provided in the middle of the nut welding box 4. This structure allows the nut welding box 4 to correspond to the swing arm bushing mounting hole 101 through the through hole 401, and the through hole 401 and the swing arm bushing mounting hole 101 are both round Hole structure, and the size of the through hole 401 is larger than the size of the swing arm bushing mounting hole 101. This structure can eliminate the problem of concentricity error between the through hole 401 and the swing arm bushing mounting hole 101 through the size difference between the through hole 401 and the swing arm bushing mounting hole 101, thereby improving the bolt assembly efficiency. After the cross-shaped structure of the nut welding box 4 is stamped, the two opposite sides respectively form a nut intercepting leg 402 and a welding leg 403. This structure allows the nut welding box 4 to be engaged and limited by the nut 5 of the matching nut intercepting leg 402 and the welding leg 403, and the welding leg 403 enables the nut welding box 4 to be welded to the swing arm bushing mounting bracket body 1, and the welding leg 403 is welded and fixed to the swing arm bushing mounting bracket body 1, and the nut The intercepting leg 402 is in clearance with the swing arm bushing mounting bracket body 1. This structure can reduce the welding parts, and intercept the square nut 5 through the nut intercepting leg 402 to prevent the square nut 5 from falling from the nut welding box 4. The nut intercepting leg 402 can be bent, and the square nut 5 can be replaced without disassembling the nut welding box 4. The square nut 5 is clamped in the nut welding box 4. The square nut 5 is in clearance with the swing arm bushing mounting bracket body 1 and the nut welding box 4, and a threaded hole 501 is opened on the square nut 5. This structure allows the square nut 5 to fix the swing arm bushing through the threaded hole 501, so that the swing arm bushing can be installed and fixed to the swing arm 3 under the positioning of the swing arm bushing mounting bracket body 1.The square nut 5 is located between the swing arm bushing mounting bracket body 1 and the nut welding box 4, and the size of the threaded hole 501 is smaller than the size of the swing arm bushing mounting hole 101. This structure can eliminate the problem of concentricity deviation between the threaded hole 501 and the swing arm bushing mounting hole 101. At the same time, the square nut 5 is movably arranged to avoid the problem of insufficient parallelism of the fixing surfaces on both sides, ensure the production qualification rate, and improve production efficiency.
[0026] Working principle: when using the swing arm bushing mounting bracket of the nut welding box structure, first, the swing arm bushing mounting hole 101 is integrally cast and formed, and the square nut 5 is placed on the U-shaped structural groove surface of the swing arm bushing mounting bracket body 1 through the tooling, and the square nut 5 corresponds to the swing arm bushing mounting hole 101. Then the nut welding box 4 is placed on the swing arm bushing mounting bracket body 1, so that the nut welding box 4 clamps the square nut 5 through the nut intercepting leg 402 and the welding leg 403, and then the welding leg 403 is welded and fixed to the swing arm bushing mounting bracket body 1, so that the through hole 401, the threaded hole 501, and the swing arm bushing mounting hole 101 are penetrated. The swing arm bushing mounting bracket body 1 is fixed to the subframe 2 by arc surface welding, and the subframe 2 is screwed and fixed to the frame structure. When assembling the swing arm bushing for fixing the swing arm 3, since the square nut 5 is in an active state, it can have a self-guiding effect, thereby eliminating the concentricity deviation of the mounting hole and the problem of insufficient parallelism of the mounting surface, thereby completing a series of work.
