Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal bracket welding technology, and more specifically, it relates to a welding fixture for metal brackets. Background Technology
[0002] Welding fixtures are a set of flexible welding fixation, clamping, and positioning jigs. They are mainly used for welding various weldable materials, including large, medium, and small materials. Welding fixtures are also used in the process of welding metal brackets.
[0003] Existing metal bracket welding fixtures use clamps to clamp and fix corresponding components on the metal bracket. However, during the welding process, welding slag is generated and falls onto the welding platform. Since the welding platform is fixedly connected to the clamping mechanism, it is not convenient to clean the welding slag on the welding platform. The presence of welding slag on the welding platform makes it difficult to place the metal bracket flat on the welding platform, affecting the quality of metal bracket production. In addition, the welding process of metal brackets generates a large amount of welding fumes, which can easily pollute the surrounding environment and affect people's health. Utility Model Content

[0029] Please see Figures 1-5 A welding fixture for a metal bracket includes a fixed platform 1, a welding platform 2, and multiple clamping mechanisms 3. The clamping mechanisms 3 adopt existing technology, and their specific structure is installed and used according to the application requirements. Two vertical seats 4 are fixedly connected to the top of the fixed platform 1, and the multiple clamping mechanisms 3 are respectively installed on the two vertical seats 4. The fixed platform 1 has notches 5 at positions corresponding to the vertical seats 4. The welding platform 2 is located inside the notches 5. A fixed plate 6 is fixedly connected to the fixed platform 1, and multiple electric cylinders 7 are installed on the fixed plate 6. The extension rods of the multiple electric cylinders 7 are all fixedly connected to the bottom end of the welding platform 2. Both sides of the top of the welding platform 2 are... A baffle 25 is fixedly connected, and slots 26 that fit the baffle 25 are provided at the bottom of the two vertical seats 4 to prevent welding slag from falling from both sides of the welding platform 2. A material drop trough 8 is formed between the fixed platforms 1 of the welding platform 2. A collection box 27 is placed below the material drop trough 8 to facilitate the collection of welding slag. A baffle 28 is fixedly connected to the fixed platform 1 at the rear side of the material drop trough 8 to block the welding slag falling from the material drop trough 8 and to facilitate the welding slag falling into the collection box 27. A cleaning plate 9 is provided inside the material drop trough 8, and a cleaning brush 10 is fixedly connected to the bottom of the cleaning plate 9. A smoke extraction mechanism is slidably provided at the top of the two vertical seats 4.
[0030] Specifically, multiple electric cylinders 7 pull the welding platform 2 downwards, separating the welding platform 2 from the clamping mechanism 3. The cleaning plate 9 slides at the bottom of the two vertical plates, and the cleaning brush 10 cleans the welding slag on the welding platform 2. This makes it easy to clean all the welding slag on the welding platform 2, preventing the welding slag from affecting the flatness of the metal bracket placed on the welding platform 2, and ensuring the quality of the welding bracket production.
[0031] Please see Figure 4Both vertical seats 4 have a sliding groove 11 at their bottom ends. A first slide seat 12 is slidably disposed inside both sliding grooves 11. The bottom ends of both first slide seats 12 are fixedly connected to the top end of the cleaning plate 9. A first screw 13 is threadedly connected inside one of the first slide seats 12. The first screw 13 is rotatably connected to the vertical seat 4. A first motor 14 that drives the first screw 13 to rotate is installed on the side end of the vertical seat 4. A support rod 15 is slidably disposed on the other first slide seat 12. The support rod 15 is fixedly connected to the corresponding vertical seat 4 and provides support for the first slide seat 12.
[0032] Specifically, the first motor 14 drives the first screw 13 to rotate. The rotation of the first screw 13 causes the first slide block 12 to slide inside the slide groove 11. The first slide block 12 drives the cleaning plate 9 and the cleaning brush 10 to move, which facilitates the cleaning of welding slag on the welding platform 2. At the same time, the cleaning plate 9 and the cleaning brush 10 are moved to the inside of the material drop trough 8, which facilitates the movement of the welding platform 2 to the inside of the slot 5.
[0033] Please see Figure 1 and Figure 2 The fume extraction mechanism includes a fume extraction box 16. Each of the two vertical supports 4 has a convex groove 17 at its top. Two convex strips 18 are fixedly connected to the bottom of the fume extraction box 16, and these strips slidably engage with the two convex grooves 17. Multiple fume extraction ports 19 are evenly distributed at the bottom of the fume extraction box 16. A fume extraction pipe 20, connected to a welding fume purifier, is connected to the top of the fume extraction box 16 to facilitate the extraction of welding fumes. Two fixing blocks 21 are fixedly connected to the top of one vertical support 4, and a second screw 22 is rotatably connected between the two fixing blocks 21. A second slide block 23 is fixedly connected to the side of the fume extraction box 16, and the second slide block 23 is threadedly connected to the second screw 22. A second motor 24 is mounted on one fixing block 21, and the output end of the second motor 24 is fixedly connected to the side of the second screw 22, facilitating the adjustment of the fume extraction box 16 to the rear for easy hoisting of the metal support.
[0034] Specifically, during the welding of the metal bracket, a welding fume purifier connected to the outside of the fume extraction pipe 20 operates. The welding fumes generated during the welding process are drawn away through multiple fume extraction ports 19, fume extraction box 16, and fume extraction pipe 20, preventing the welding fumes from dispersing into the surrounding air and affecting the environment and people's health. The second motor 24 drives the second screw 22 to rotate counterclockwise. The counterclockwise rotation of the second screw 22 causes the second slide block 23 to move backward relative to the second screw 22. The second slide block 23 drives the fume extraction box 16 to move backward, making it easier to lift the metal bracket and avoiding the need to lift heavy metal brackets, thus improving its practicality.
[0035] In summary, when using the overall equipment:
[0036] The metal bracket to be welded is placed or hoisted onto the welding platform 2. Multiple clamping mechanisms 3 clamp and fix multiple components on the metal bracket. Then, the second motor 24 drives the second screw 22 to rotate clockwise. The clockwise rotation of the second screw 22 moves the second slide 23 and the fume extraction box 16 above the metal bracket. Welding is then performed between the metal components. During the welding process, a welding fume purifier connected to the outside of the fume extraction pipe 20 operates, and the welding fumes generated during the welding process are extracted through multiple fume extraction ports 19, the fume extraction box 16, and the fume extraction pipe 20. After welding is completed, the second motor 24 drives the second screw 22 to rotate counterclockwise. The counterclockwise rotation of the second screw 22 moves the second slide 23 backward relative to the second screw 22. The second slide 23 moves the fume extraction box 16 backward. The rear side is moved so that the smoke box 16 is moved to the rear side, and then the metal bracket is lifted away. Then, the welding platform 2 is pulled to the bottom side by multiple electric cylinders 7. Then, the first screw 13 is driven to rotate counterclockwise by the first motor 14, so that the first slide 12, cleaning plate 9 and cleaning brush 10 are moved to the front side. Then, the welding platform 2 is pushed upward by multiple electric cylinders 7, so that the top of the welding platform 2 contacts the cleaning brush 10. Then, the first screw 13 is driven to rotate clockwise by the first motor 14. The clockwise rotation of the first screw 13 moves the slide, cleaning plate 9 and cleaning brush 10 forward. The cleaning brush 10 cleans the welding slag on the welding platform 2 and pushes it into the inside of the discharge chute 8. The welding slag falls into the inside of the collection box 27 through the discharge chute 8 and is collected by the collection box 27.
[0037] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
