Description

Technical Field

[0001] This invention relates to the field of angle steel welding technology, specifically to an automatic welding device for angle steel tower plates. Background Technology

[0002] In power transmission, angle steel towers need to be erected. Before assembly, some angle steel sections need to be welded and fixed to facilitate subsequent tower assembly. Traditional angle steel welding processes generally suffer from cumbersome fixing, low efficiency, and insufficient quality stability. Currently, angle steel welding mainly relies on manual operation, requiring temporary fixing of the workpiece through manual alignment and tack welding before welding. However, due to their large length-to-diameter ratio and irregular cross-section, angle steel is prone to vibration or displacement during manual fixing, resulting in excessively large welding gaps (up to 1-3 mm) and angle deviations (above ±2°). This directly affects weld penetration and structural strength, and can even lead to workpiece scrap, with material waste rates as high as 5%-8%.

[0003] Existing fixing methods mostly employ simple tooling or manual support, resulting in cumbersome operation steps: requiring 2-3 workers to coordinate positioning, clamping, and adjustment, with fixing a single set of angle steel taking approximately 15-20 minutes, accounting for over 40% of the overall welding cycle. Furthermore, during manual welding, the electrode angle and welding speed rely heavily on the welder's experience, making defects such as magnetic blow, incomplete penetration, and slag inclusions prone to occur, resulting in a weld pass rate of only around 85%. In addition, traditional processes demand high worker skills and involve risks such as high temperatures and dust, failing to meet the efficient and safe development needs of modern manufacturing.

[0004] Therefore, we propose an automatic welding device for angle steel tower steel plates. Summary of the Invention

The fixing mechanism 2 is fixedly installed on the top of the workbench 1. The fixing mechanism 2 includes an L-shaped placement plate 4, a baffle 3 fixedly installed on the top of the workbench 1, a first mounting groove 5 disposed at one end of the L-shaped placement plate 4, a first fixing plate 6 disposed in the first mounting groove 5, a first top block 61 disposed on the first fixing plate 6, a U-shaped connecting plate 7 installed on the upper part of the first fixing plate 6, a threaded sleeve 8 fixedly installed on the U-shaped connecting plate 7, a first threaded rod 9 installed in the threaded sleeve 8, a top plate 10 fixedly installed on the upper end of the first threaded rod 9, and a plum blossom knob 11 fixedly installed on the top plate 10. Nut 13 is fixedly installed on plum blossom knob 11. Second mounting groove 15 is set on the upper part of L-shaped placement plate 4. Mounting shaft 16 is installed in second mounting groove 15. First connecting rod 14 is fixed on mounting shaft 16. U-shaped fixing plate 12 is fixedly installed on first connecting rod 14. Second top block 121 is set at the lower part of U-shaped fixing plate 12. Guide rail 17 is fixedly installed on the right half of the top of workbench 1. Two sets of guide rail 17 are provided. U-shaped mounting bracket 18 is installed on guide rail 17. Second connecting rod 19 is installed at the lower part of U-shaped mounting bracket 18. Second threaded rod 20 is set in the middle of second connecting rod 19. Second fixing plate 21 is fixedly installed on the top of workbench 1. First servo motor 22 is installed on the right side of second fixing plate 21. To weld the angle steel, place it on the left side of the baffle 3. Pass the angle steel to be welded through the U-shaped fixing plate 12 and between the first fixing plate 6 and the L-shaped placement plate 4, and place it on the L-shaped placement plate, so that the two sets of angle steel to be welded are in contact. Make the angle steel placed on the L-shaped placement plate 4 press against the angle steel placed on the left side of the baffle 3. Turn the plum blossom knob 11. The plum blossom knob 11 drives the first threaded rod 9 to rotate through the top plate 10. The first threaded rod 9 cooperates with the threaded sleeve 8. The threaded sleeve 8 pulls the first fixing plate 6 through the U-shaped connecting plate 7. The first fixing plate 6 is installed in the first mounting groove 5 through the pin. A fixing plate 6 rotates via a pin. A first top block 61 on the first fixing plate 6 presses and fixes the bottom of the angle steel. The top block 10 pushes the U-shaped fixing plate 12, which rotates via the first connecting rod 14 and the mounting shaft 16. A second top block 121 on the U-shaped fixing plate 12 presses and fixes the upper side of the angle steel, fixing the angle steel onto the L-shaped placement plate 4. At the same time, the angle steel placed on the L-shaped placement plate 4 presses and clamps the angle steel placed on the left side of the baffle 3, fixing the angle steel that needs to be welded, facilitating welding. The nut is turned using a tool (such as a wrench). 13. Nut 13 drives the plum blossom nut 11 to rotate, tightening the first threaded rod 9 to stably fix the angle steel. The rotation of the first threaded rod 9 engages with the threaded sleeve 8, causing the U-shaped fixing plate 12 and the first fixing plate 6 to rotate, quickly fixing the angle steel. The bottom and upper side of the angle steel are simultaneously fixed and stably secured. The fixing mechanism 2 is operated sequentially to complete the fixing of the angle steel, enabling single-person operation for fixing and welding the angle steel, improving the welding quality between welded angle steels. Simultaneously, rotating nut 13 and plum blossom knob 11 in different directions causes the U-shaped fixing plate 12 and... Rotating the first fixing plate 6 quickly loosens the fixing of the angle steel, unscrewing the first threaded rod 9 out of the threaded sleeve 8. The first threaded rod 9 disengages from the threaded sleeve 8. Rotating the first fixing plate 6 opens the L-shaped placement plate 4, allowing for quick disassembly of the welded angle steel. The first servo motor 22 is started, driving the second threaded rod 20 to rotate. The second connecting rod 19 has a threaded hole that mates with the second threaded rod 20.
