Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment technology, and specifically relates to an automatic welding machine for angle steel processing. Background Technology

[0002] Angle steel, as a common profile, is widely used in building steel structures, warehouse racking, and machinery frames due to its good cross-sectional stability and strong load-bearing capacity. In the production and processing of angle steel in these fields, butt welding is one of the core processes, and the welding quality directly determines the structural strength and service life of the final product.

[0003] Problems with existing technology: Existing automatic angle steel welding machines have significant limitations in their functional design, making it difficult to adapt to the diverse needs of different fields for multi-angle welding. The welding mechanism and clamping positioning structure of current mainstream equipment are mostly fixed modular designs, which can only preset to achieve two single angle steel butt welding methods - either "parallel butt welding" of two angle steels (such as the parallel splicing of shelf beams and reinforcing ribs) or "vertical right angle welding" (such as the 90° vertical connection of the column and beam of the equipment frame). They can only achieve parallel welding or vertical welding, lacking the ability to flexibly adjust multi-dimensional angles, which reduces the flexibility and practicality of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an automatic welding machine for angle steel processing. By setting up a worm gear, worm, support shaft, angle line and pointer, rotating the handle on the worm can drive the worm gear and support shaft to rotate, thereby adjusting the welding angle of the angle steel on the first fixing mechanism. Combined with the pointer and angle line, the angle can be precisely adjusted, effectively improving the flexibility and accuracy of the equipment.

[0005] The specific technical solution adopted by this utility model is as follows: An automatic welding machine for processing angle steel includes a worktable, the interior of which is provided with an installation groove, and a support shaft is rotatably mounted inside the installation groove; The outer wall of the support shaft is provided with a worm gear, and a worm gear that meshes with the worm gear is rotatably installed on the inner side of the mounting groove. The top end of the support shaft extends to the top of the workbench and is provided with a first fixing mechanism. A moving mechanism is provided inside the mounting groove and on one side of the support shaft. The output end of the moving mechanism is provided with a moving plate, and two sliding grooves are opened on the top of the moving plate. A slider is slidably installed inside the slide groove. A spring is fixed to one side of the slider and fixed to the inside of the slide groove. A second fixing mechanism is provided between the tops of the two sliders.

[0006] The moving mechanism includes a first lead screw rotatably mounted on the inner side of the mounting groove, a moving block threaded onto the outer wall of the first lead screw, and a moving groove slidably connected to the moving block through the top of the worktable. The two moving blocks are the output ends of the moving mechanism.

[0007] A robotic arm is provided on one side of the top of the workbench, and a welding gun is provided at the output end of the robotic arm.

[0008] The first fixing mechanism and the second fixing mechanism include a U-shaped plate, a hydraulic cylinder is provided on the outer side of the U-shaped plate, and the output shaft of the hydraulic cylinder extends to the inner side of the U-shaped plate where a clamping plate is provided.

[0009] One end of the first lead screw and worm gear extends outside the worktable and is equipped with a crank handle.

[0010] The top of the worktable has an angle line with the support shaft as the origin, and the top of the support shaft has a pointer that matches the angle line.

[0011] The technical effects achieved by this utility model are as follows: This invention, through the combination of a worm gear, a worm shaft, a support shaft, an angle line, and a pointer, allows the worm gear and support shaft to rotate when the crank on the worm shaft is turned, thereby adjusting the welding angle of the angle steel on the first fixing mechanism. Combined with the pointer and angle line, precise angle adjustment can be achieved, effectively improving the flexibility and accuracy of the equipment.

[0012] This utility model utilizes the cooperation of the first lead screw, the moving block, and the moving groove in the moving mechanism. By rotating the crank on the first lead screw, the moving block and the moving plate can be moved, thereby adjusting the front and rear positions of the angle steel on the second fixing mechanism. This further enhances the flexibility of the equipment in welding angle steel, and the crank makes operation more labor-saving.

[0013] This invention utilizes a slider, a groove, and a spring below the second fixing mechanism. After the angle steel is clamped by the second fixing mechanism, the spring force can push the slider to slide, ensuring a tight fit between the angle steel on the second fixing mechanism and the angle steel on the first fixing mechanism, preventing gaps between them and significantly improving welding quality.

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figures 1-3 As shown, an automatic welding machine for angle steel processing includes a worktable 1, the inside of which is provided with an installation groove 2, and a support shaft 3 is rotatably installed inside the installation groove 2. The outer wall of the support shaft 3 is provided with a worm gear 4, and the inner side of the mounting groove 2 is rotatably mounted with a worm 5 that meshes with the worm gear 4. The top of the support shaft 3 extends to the top of the worktable 1 and is provided with a first fixing mechanism. The worm gear 5 drives the worm wheel 4 to rotate, the worm wheel 4 drives the support shaft 3 to rotate, and the support shaft 3 drives the angle steel on the first fixed mechanism to rotate, thereby adjusting the welding angle of the angle steel and improving the flexibility of equipment use.

[0018] Inside the mounting slot 2 and on one side of the support shaft 3, there is a moving mechanism. The output end of the moving mechanism is provided with a moving plate 9. Two sliding grooves 11 are opened on the top of the moving plate 9. A slider 10 is slidably installed inside the slide groove 11. A spring 12, which is fixed to the inside of the slide groove 11, is fixed on one side of the slider 10. A second fixing mechanism is provided between the tops of the two sliders 10.

[0019] According to the above structure, after the angle steel is clamped by the second fixing mechanism, the spring 12 pushes the angle steel on the second fixing mechanism to fit tightly with the other angle steel through the elastic force of the spring 12, so that the angle steel on the second fixing mechanism and the angle steel on the first fixing mechanism fit tightly together, avoiding gaps between them and significantly improving the welding quality.

[0020] like Figure 1 and Figure 3 As shown, the moving mechanism includes a first lead screw 6 rotatably mounted on the inner side of the mounting groove 2, a moving block 7 threadedly connected to the outer wall of the first lead screw 6, and a moving groove 8 slidably connected to the moving block 7 through the top of the worktable 1. The two moving blocks 7 are the output ends of the moving mechanism.

[0021] According to the above structure, rotating the first lead screw 6 drives the moving block 7 to move, the moving block 7 drives the moving plate 9 to move, and the moving plate 9 drives the angle steel on the second fixing mechanism to move back and forth, which improves the flexibility of welding the angle steel.

[0022] like Figure 1 As shown, a robotic arm 17 is provided on one side of the top of the workbench 1, and a welding gun 18 is provided at the output end of the robotic arm 17.

[0023] like Figure 1 As shown, the first fixing mechanism and the second fixing mechanism include a U-shaped plate 13, a hydraulic cylinder 15 is provided on the outer side of the U-shaped plate 13, and the output shaft of the hydraulic cylinder 15 extends to the inner side of the U-shaped plate 13 where a clamping plate 14 is provided.

[0024] Based on the above structure, it is convenient to clamp and fix the angle steel. Two angle steels that need to be welded to each other are placed into the U-shaped plate 13. The hydraulic cylinder 15 is started to drive the clamping plate 14 to move. The clamping plate 14 cooperates with the side wall of the U-shaped plate 13 to clamp the angle steel, which improves the stability of angle steel welding.

[0025] like Figure 1 As shown, one end of the first lead screw 6 and the worm gear 5 extends to the outside of the worktable 1 and is equipped with a crank handle 16.

[0026] Based on the above structure, the crank handle 16 can easily and conveniently rotate the first lead screw 6 or the worm gear 5, making the use of the equipment less strenuous. like Figure 1 As shown, the top of the worktable 1 has an angle line with the support shaft 3 as the origin, and the top of the support shaft 3 has a pointer that matches the angle line.

[0027] Based on the above structure, the combination of the angle line and the pointer allows for precise adjustment of the welding angle of the angle steel on the first fixing mechanism, thus improving the practicality of the equipment.

[0028] The working principle of this utility model is as follows: When in use, firstly, the first angle steel to be welded is placed into the U-shaped plate 13 of the first fixing mechanism, and the hydraulic cylinder 15 is started. The hydraulic cylinder 15 drives the clamping plate 14 to move towards the angle steel. The clamping plate 14 cooperates with the inner side wall of the U-shaped plate 13 to achieve clamping and fixing of the angle steel. Then, the second angle steel to be welded is placed into the U-shaped plate 13 of the second fixing mechanism, and the above clamping operation is repeated. When the angle steel is clamped by the second fixing mechanism, the corresponding U-shaped plate 13 is pulled, so that the spring 12 generates elastic force due to the force state of the slider 10, pushing the slider 10 to slide in the slide groove 11. When the welding points of the two angle steels are aligned, the angle steel on the second fixing mechanism is driven to move closer to the angle steel on the first fixing mechanism and fit tightly together. To adjust the welding angle, turn the handle 16 at one end of the worm 5. The handle 16 drives the worm 5 to rotate, the worm 5 meshes with and drives the worm wheel 4 to rotate, the worm wheel 4 drives the support shaft 3 to rotate synchronously, and the support shaft 3 drives the first fixing mechanism and the clamped angle steel to rotate. By observing the corresponding position of the pointer at the top of the support shaft 3 and the angle line at the top of the worktable 1, the required welding angle can be determined and then the handle 16 can be stopped. To adjust the front and back position of the angle steel, turn the handle 16 at one end of the first lead screw 6. The handle 16 drives the first lead screw 6 to rotate. The first lead screw 6 drives the moving block 7, which is threaded on the outer wall, to slide along the moving groove 8. The moving block 7 drives the moving plate 9 at the top to move synchronously. The moving plate 9 then drives the second fixing mechanism and the angle steel being clamped to move back and forth until it is adjusted to a suitable welding position. Finally, the robotic arm 17 is started, which moves the welding gun 18 at the output end to the welding position to perform automatic welding on the angle steel. After welding is completed, the robotic arm 17 and welding gun 18 are turned off, and the hydraulic cylinder 15 is controlled to drive the clamping plate 14 to reset, so that the welded angle steel can be removed.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
