Description

Technical Field

[0001] This utility model relates to the field of thin plate welding technology, and in particular to a mechanically fine-tuning welding trolley for splicing long weld seams in thin plates. Background Technology

[0002] Thin plates refer to relatively thin metal sheets, usually less than six millimeters thick. Compared to other thicker metal sheets, thin plates are thinner and lighter. During the splicing of thin plates, especially when a long seam is formed between two thin plates, a welding carriage is needed to move steadily along the seam to ensure the uniform distribution of welding points.

[0003] Although traditional welding carriages can complete the welding of long seams in thin plates, it is not convenient to adjust the position of the welding carriage during welding. Different welding tasks have different requirements for the carriage's running path and angle. Traditional carriages are difficult to adjust in this case, resulting in problems such as uneven weld width and inconsistent weld depth, which affects the welding quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mechanically fine-tuning welding trolley for thin plate splicing long welds. It aims to improve the existing technology where it is inconvenient to adjust the position of the welding trolley during welding. Different welding tasks have different requirements for the running path and angle of the trolley. Traditional trolleys are difficult to adjust in this case, resulting in problems such as uneven weld width and inconsistent welding depth.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A mechanically fine-tuning welding trolley for splicing long welds of thin plates includes a fixed frame, a horizontal plate fixedly connected to the lower part of the fixed frame, a fume treatment component provided on the upper part of the horizontal plate, and a fine-tuning component provided on the upper part of the fixed frame.

[0007] The fine-tuning component includes a rack plate, which is fixedly connected to the upper front side of the fixed frame. A slider is provided on the outside of the rack plate, and a mounting bracket is fixedly connected to the upper part of the slider. A motor is provided on the left side of the mounting bracket, and a gear is fixedly connected to the output end of the motor. The gear is rotatably connected inside the mounting bracket and meshes with the rack plate. A fixing bracket is fixedly connected to the right side of the mounting bracket, and a lead screw is threadedly connected inside the fixing bracket. A handwheel is fixedly connected to the right side of the lead screw, and a moving block is threadedly connected to the outside of the lead screw. A limit block is fixedly connected to the lower part of the moving block, and an adjusting bracket is fixedly connected to the outside of the moving block. An adjusting block is slidably connected inside the adjusting bracket, and a fixing component is provided outside the adjusting block.

[0008] Furthermore, the smoke treatment assembly includes a treatment box, which is fixedly connected to the upper part of the horizontal plate. A fan is fixedly connected to the right side of the outside of the treatment box, and an air outlet is fixedly connected to the output end of the fan. The input end of the fan is fixedly connected to the inside of the treatment box. A filter plate is inserted into the left side of the inside of the treatment box, and an activated carbon plate is inserted into the right side of the inside of the treatment box. A conveying pipe is fixedly connected to the left side of the outside of the treatment box, and a smoke collection hood is fixedly connected to the right side of the outside of the adjusting block. The top of the conveying pipe is fixedly connected to the inside of the smoke collection hood.

[0009] Furthermore, the fixing component includes electric push rods, which are fixedly connected to both sides inside the adjusting block. The output ends of the two electric push rods are fixedly connected to mounting rods, and welding gun clamps are fixedly connected to the outside of the two mounting rods.

[0010] Furthermore, a groove is provided on the upper part of the fixed frame, and the slider is slidably connected inside the groove.

[0011] Furthermore, a mounting ring is fixedly connected to the outer left side of the mounting bracket, and the motor is fixedly connected inside the mounting ring.

[0012] Furthermore, a limiting groove is formed inside the fixing frame, and the limiting block is slidably connected inside the limiting groove.

[0014] Furthermore, both welding torch clamps are equipped with protective pads inside, and the protective pads are made of rubber.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when adjusting the lateral position of the welding torch, the motor is started, the motor drives the gear to rotate, and drives the mounting frame to move laterally along the rack plate, thereby driving the fixed frame and the welding carriage to move, thus realizing lateral adjustment; when moving longitudinally, the handwheel is turned, which drives the lead screw to rotate, thereby driving the moving block and the welding carriage to move. This design allows the welding carriage to flexibly adjust its position to adapt to welding tasks of different shapes and positions, avoid uneven welds or inconsistent depths, and improve welding quality.

[0017] 2. In this utility model, during welding, the fan is started to draw the smoke through the fume hood and send it to the treatment box through the conveying pipe. The smoke first passes through the filter plate to filter impurities, then passes through the activated carbon plate to remove harmful substances, and finally is discharged through the air outlet, thus completing the filtration and purification of the smoke and improving the air quality of the working environment.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 , Figure 2 and Figure 6An embodiment of this utility model is provided: a mechanically fine-tuning welding trolley for thin plate splicing long weld seams, including a fixed frame 1, a horizontal plate 2 fixedly connected to the lower part of the fixed frame 1, a fume treatment component provided on the upper part of the horizontal plate 2, which facilitates the filtration and purification of the fume generated during welding, and a fine-tuning component provided on the upper part of the fixed frame 1, which facilitates the adjustment of the position of the welding trolley.

[0029] The fine-tuning component includes a rack plate 3, which is fixedly connected to the upper front side of the fixed frame 1. A slider 5 is provided on the outside of the rack plate 3, and a mounting bracket 4 is fixedly connected to the upper part of the slider 5. A motor 8 is provided on the left side of the mounting bracket 4, and a gear 9 is fixedly connected to the output end of the motor 8. The gear 9 is rotatably connected inside the mounting bracket 4 and meshes with the rack plate 3. A fixing bracket 10 is fixedly connected to the right side of the mounting bracket 4. A lead screw 20 is threadedly connected inside the fixing bracket 10. A handwheel 19 is fixedly connected to the right side of the lead screw 20. A moving block 21 is threadedly connected to the outside of the lead screw 20. A limit block 22 is fixedly connected to the lower part of the moving block 21. An adjusting frame 24 is fixedly connected, and an adjusting block 25 is slidably connected inside the adjusting frame 24. A fixing component is provided on the outside of the adjusting block 25 to facilitate the fixing of the welding torch. A sliding groove 6 is provided on the upper part of the fixing frame 1, and a slider 5 is slidably connected inside the sliding groove 6 to facilitate the movement of the slider 5. An mounting ring 7 is fixedly connected to the left side of the mounting frame 4, and a motor 8 is fixedly connected inside the mounting ring 7 to facilitate the fixing of the motor 8. A limiting groove 23 is provided inside the fixing frame 10, and a limiting block 22 is slidably connected inside the limiting groove 23 to facilitate the movement of the limiting block 22.

[0030] Specifically, when the welding carriage position needs to be adjusted laterally, the motor 8 is started first. The motor 8 drives the gear 9 fixed at the output end to rotate, allowing the gear 9 to move on the upper part of the rack plate 3. As the gear 9 moves on the upper part of the rack plate 3, it also moves the externally rotating mounting bracket 4 synchronously. During this process, the fixed bracket 10 is moved, and the movement of the fixed bracket 10 directly affects the lateral position of the welding carriage. When adjusting longitudinally, the handwheel 19 is turned first. The handwheel 19 is connected to the lead screw 20. The rotation of the handwheel 19 drives the lead screw 20 to rotate inside the fixed bracket 10. The rotation of the lead screw 20 drives the movement of the threaded moving block 21, and the movement of the moving block 21 directly changes the longitudinal position of the welding carriage. By combining the lateral and longitudinal adjustment functions, the welding carriage can flexibly adapt to various complex welding tasks, ensuring the continuity of the welding process and the consistency of the weld, thereby improving welding efficiency.

[0031] Reference Figure 3 , Figure 4 and Figure 7The fume treatment assembly includes a treatment box 11, which is fixedly connected to the upper part of the horizontal plate 2. A fan 12 is fixedly connected to the right side of the outside of the treatment box 11. An air outlet 13 is fixedly connected to the output end of the fan 12, and the input end of the fan 12 is fixedly connected to the inside of the treatment box 11. A filter plate 14 is inserted into the left side of the inside of the treatment box 11 to facilitate the filtration of impurities in the fume. An activated carbon plate 15 is inserted into the right side of the inside of the treatment box 11 to facilitate the filtration of harmful substances in the fume. A conveying pipe 16 is fixedly connected to the left side of the outside of the treatment box 11. A fume hood 17 is fixedly connected to the right side of the outside of the adjusting block 25 to facilitate the collection of welding fumes. The top of the conveying pipe 16 is fixedly connected to the inside of the fume hood 17. A guide ring 18 is fixedly connected to the outside of the fixing frame 10, and the conveying pipe 16 is slidably connected to the inside of the guide ring 18 to facilitate the support of the conveying pipe 16.

[0032] Specifically, during the welding process, the fan 12 is first started. The airflow generated by the fan 12 draws the welding fumes into the fume hood 17. The drawn-in fumes flow through the fume hood 17 into the conveying pipe 16, which connects the fume hood 17 to the treatment box 11, ensuring that the fumes are quickly and smoothly transported into the treatment box 11. After entering the treatment box 11, the welding fumes first come into contact with the filter plate 14. The filter plate 14 mainly removes large particulate impurities from the fumes. Next, the fumes filtered by the filter plate 14 will continue to pass through the activated carbon plate 15 for further purification. The activated carbon plate 15 can effectively adsorb harmful gases in the fumes. After being treated by the filter plate 14 and the activated carbon plate 15, most of the harmful substances and impurities have been removed from the fumes. Finally, the purified fumes are discharged through the air outlet 13 of the treatment box 11. This multi-stage filtration (the combination of the filter plate 14 and the activated carbon plate 15) removes different types of pollutants from the fumes during welding, ensuring that the fumes are effectively treated and that the welding area is clean.

[0033] Reference Figure 5 and Figure 7 The fixing component includes electric push rods 26, which are fixedly connected to both sides inside the adjusting block 25. The output ends of the two electric push rods 26 are fixedly connected to mounting rods 27, and welding gun clamps 28 are fixedly connected to the outside of the two mounting rods 27. The welding gun clamps 28 are used to fix the welding gun. The inside of the two welding gun clamps 28 is provided with protective pads made of rubber. The protective pads can protect the welding gun, reduce damage to the surface of the welding gun, and extend the service life of the welding gun.

[0034] Specifically, when fixing the welding torch, first, place the welding torch in the middle of the two welding torch clamps 28. Then, start the two electric push rods 26 to move the two mounting rods 27 fixed at the output end relative to each other. The relative movement of the two mounting rods 27 moves the externally fixed welding torch clamps 28 relative to each other. The welding torch can be fixed by the relative movement of the two welding torch clamps 28.

[0035] Working principle: When it is necessary to adjust the position of the welding carriage by adjusting the welding torch laterally, firstly, start the motor 8. The motor 8 drives the gear 9 fixed at the output end to rotate. The rotation of the gear 9 causes the externally rotating mounting bracket 4 to move laterally on the upper part of the rack plate 3. At the same time as the mounting bracket 4 moves, the externally fixed fixing bracket 10 moves. The movement of the fixing bracket 10 causes the externally mounted welding carriage to move, thus completing the lateral movement of the welding carriage. When moving the welding carriage longitudinally, firstly, turn the handwheel 19. The rotation of the handwheel 19 causes the externally fixed lead screw 20 to rotate inside the fixing bracket 10. When the lead screw 20 rotates, it causes the externally threaded moving block 21 to move. The movement of the moving block 21 causes the externally mounted welding carriage to move. This realizes the convenient lateral or longitudinal adjustment of the position of the welding carriage, which can adapt to various complex welding, such as welding parts of different shapes, or performing welding operations in different positions, avoiding problems such as uneven weld width and inconsistent welding depth, thereby improving the welding quality.

[0036] During welding, the fan 12 is started, and the welding fumes are drawn into the fume hood 17. Then, they are transported to the interior of the treatment box 11 through the conveying pipe 16. The fumes entering the treatment box 11 are first filtered by the filter plate 14 to remove impurities, and then by the activated carbon plate 15 to remove harmful substances. Finally, the filtered fumes are discharged through the air outlet 13. This method facilitates the filtration and purification of welding fumes during welding, thereby improving the air quality in the workplace.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
