Technical Field
[0001] This utility model relates to the field of welding positioning, and in particular to a bracket positioning structure. Background Technology
[0002] Tooling is a crucial guarantee in manufacturing production, influencing process level, product quality, and labor efficiency. Tooling positioning, in particular, is a vital link in ensuring product quality during the machining process. Incorrect or inaccurate workpiece positioning can affect the workpiece's dimensions and geometric tolerances, leading to scrap or increased defect rates. Traditional tooling positioning techniques, due to limitations in design concepts, technical means, and external factors, suffer from the following typical technical pain points, which directly impact machining quality and production efficiency: 1.

Uncontrolled thermal deformation: Traditional tooling cannot compensate for localized workpiece deformation caused by thermal expansion; 3. Accumulated error: Complex clamping of processes leads to multiple clamping and positioning errors in a single process, resulting in accumulated errors. Utility Model Content

This ensures the welding accuracy, has high structural strength, small cumulative dimensional error, and avoids welding deformation caused by local high temperature during welding. 2. The cooperation between the slider and the guide rail ensures the stability of the lifting U-shaped support.

At the same time, after the fixing cylinder is activated, the telescopic end of the fixing cylinder is inserted into the fixing hole, which can prevent the support frame from shaking too much.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.
[0015] Example: Please refer to Figures 1-4 As shown, this utility model provides a bracket positioning structure. The lifting structure 1 includes a fixed U-shaped bracket 101, which serves as the main fixing component of the bracket positioning structure and can be fixed together with the welding device. The position of the bracket positioning structure can be adjusted as needed. A lifting U-shaped bracket 102 is mounted on the outer side of the fixed U-shaped bracket 101. Both the fixed U-shaped bracket 101 and the lifting U-shaped bracket 102 are inverted U-shaped structures, with one horizontal rod-like structure and two vertical rod-like structures. A vertical guide structure is provided between the vertical rods of the fixed U-shaped bracket 101 and the lifting U-shaped bracket 102. There are two sets of vertical guide structures. The design of the two sets of symmetrical vertical guide structures ensures the stability of the lifting U-shaped bracket 102's lifting and lowering movement. The vertical guide structure consists of a slider. The system consists of slider 103 and guide rail 104. Slider 103 is fixed to the inner side of the vertical rod of the lifting U-shaped bracket 102. Guide rail 104, which cooperates with slider 103, is fixed to the outer side of the vertical rod of the fixed U-shaped bracket 101. A concave-convex block structure is provided between the horizontal rod of the lifting U-shaped bracket 102 and slider 103. The concave-convex block structure includes concave block 105 and convex block 106. Concave block 105 is provided below the horizontal rod of the lifting U-shaped bracket 102. Concave block 106, which cooperates with concave block 105, is provided above the horizontal rod of the lifting U-shaped bracket 102. The horizontality of the lifting U-shaped bracket 102 can be ensured by the support of the concave-convex block structure. Telescopic cylinder 107 is fixed below the horizontal rod of the fixed U-shaped bracket 101. The telescopic end of telescopic cylinder 107 is connected to the lifting U-shaped bracket 102.
[0016] like Figures 1-4As shown, the flipping structure 2 includes a first L-shaped bracket 202, which is fixed to the top surface of the lifting U-shaped bracket 102. Ribs are provided at the inner corners of the first L-shaped bracket 202 to ensure its stability and strength. A flipping cylinder 201 is fixed to the side of the first L-shaped bracket 202, and a support frame 205 is fixed to the flipping end of the cylinder 201. A second L-shaped bracket 203 is fixed to the inner side of the first L-shaped bracket 202, and a fixing cylinder 204 is embedded in the inner side of the second L-shaped bracket 203. The bottom surface of the support frame 205 is fixed... A fixing hole 206 is provided to cooperate with the fixing cylinder 204. Since the fixing cylinder 204 can extend and retract, when the support frame 205 is in a horizontal state, the extension end of the fixing cylinder 204 is inserted into the fixing hole 206, which can prevent the support frame 205 from flipping or shaking too much. In addition, a concave-convex block structure is provided between the support frame 205 and the second L-shaped bracket 203. The concave-convex block structure can keep the support frame 205 in a horizontal state and improve accuracy. A concave block 105 is fixed at the bottom of the support frame 205, and a convex block 10 is provided on the top surface of the second L-shaped bracket 203.
[0017] like Figures 1-4 As shown, the lateral positioning structure 4 includes a fourth L-shaped bracket 401. The fourth L-shaped bracket 401 serves as the main connecting component, enabling the lateral positioning structure 4 to be stably connected to the support frame 205. The fourth L-shaped bracket 401 is fixed to the side of the support frame 205. A limiting side plate 402 is fixed to the outer side of the fourth L-shaped bracket 401, which provides lateral limiting for the product 6 and provides initial limiting for the product 6. A connecting block 403 is fixed to the other side of the fourth L-shaped bracket 401, and a positioning pin 405 is fixed on the connecting block 403. The positioning pin 405 can be inserted into the positioning hole provided with the product to position the positioning pin 405. A support plate 404 is fixed to the side of one of the connecting blocks 403 to support the product.
[0018] like Figures 1-4 As shown, the lateral positioning structure 5 includes a fifth L-shaped bracket 501, which is fixed to the bottom surface of the support frame 205. A downward-facing magnet 503 is fixed on the fifth L-shaped bracket 501. The magnet 503 can magnetically attract the product 6 for initial fixation. A lateral limiting block 502 is fixed on the fifth L-shaped bracket 501 near the inside. A push switch 504 is fixed on the side of the fifth L-shaped bracket 501.
[0019] like Figures 1-4 As shown, the clamping structure 3 includes a third L-shaped bracket 301, which is fixed on the top surface of the support frame 205. A clamping cylinder 302 is fixed on the side of the third L-shaped bracket 301, and clamping claws 303 located on both sides of the support frame 205 are fixed on the movable claw of the clamping cylinder 302. Specific working principle: Product 6 is placed against the fifth L-shaped bracket 501 and magnetically fixed by magnet 503. It can also be limited by the limiting side plate 402. After product 6 presses the button switch 504, the clamping structure 3 can be activated to clamp and fix product 6. Then, the flipping structure 2 is flipped to move product 6 to the vicinity of the welding position. Finally, the lifting structure 1 accurately delivers product 6 to the welding position.
[0020] In this application, Figure 1 As a reference frame, the flipping structure 2 is above the lifting structure 1, and vice versa. Moreover, the vertical orientation of this application is limited to the orientation of this application. In actual use and installation, the positioning structure of this application can be inverted or its orientation can be adjusted as needed to facilitate welding.
