Description

Technical Field

[0001] The invention relates to the technical field of welding structures, and in particular to an automatic welding device for a box-type structure. Background Art

[0002] The box structure is a hollow structure with a solid exterior, similar to the shape of a box. This structure is widely used in the engineering field. For example, the box steel structure refers to a steel structure composed of box-shaped steel materials, which has the advantages of simple structure, good rigidity, high strength and good durability. The box structure is composed of trough plates and side plates, and can withstand the load transmitted from the upper structure and the overall bending caused by the uneven foundation reaction force.

[0003] When welding the trough plate and the side plate of the box-type structure, the end plate and the trough plate need to be butted together by a clamping mechanism, and then the workers use a handheld welding mechanism to weld them. However, this welding method is time-consuming and laborious because the box-type structure is relatively large and welding is required both inside and outside. At the same time, since it is necessary to direct the end plate and the trough plate carried by the clamping structure to be butted together, a lot of time is wasted during the butt jointing, which ultimately makes the welding time-consuming and laborious.

[0004] Therefore, a device is needed to automatically butt and weld the end portion and the slot plate. Summary of the invention

[0073] Working principle:

[0074] Preparation: Install the trapezoidal end plate 61 between the rubber partitions of the spacer conveyor belt 202, and drive the double-ended lead screw 206 through the first servo motor 208, and then drive the limit rod 204 to clamp the trapezoidal end plate 61 placed above the spacer conveyor belt 202; place a plurality of overlapping trapezoidal slot plates 62 with openings facing upward on the inner side of the base bracket 102 of the base 10;

[0075] Clamping the trapezoidal slot plate 62: the sliding motor 105 drives the sliding frame 104 to move, and then drives the first sliding platform 106 to drive the end plate removal mechanism 40 to move, so that the end plate removal mechanism 40 moves to the top where a plurality of trapezoidal slot plates 62 are placed, and the first sliding platform 106 extends to drive the end plate removal mechanism 40 and then moves the end plate removal mechanism 40 to the inner side of the trapezoidal slot plate 62, and the third stepping motor 422 drives the outer ring gear 424 through the sixth gear 423 to drive the first suction cup structure 427 to rotate to adjust the angle (the outer ring gear 424 drives the connecting plate 4271 and then drives the L-shaped rod 4272 and the connecting short rod 4274 and the first electric suction cup 4273 to rotate, thereby adjusting the angle of the first electric suction cup 4273); the inner motor 4275 drives the inner ring gear 426 through the seventh gear 4276 The second suction cup structure 427 is driven to rotate to adjust the angle (the inner ring gear 426 drives the connecting plate 4271 and then drives the L-shaped rod 4272, the connecting short rod 4274 and the first electric suction cup 4273 to rotate, and then adjust the angle of the first electric suction cup 4273), the first suction cup structure 427 and the second suction cup structure 427 move synchronously towards or away from each other; the suction cup structure 427 close to the bottom of the trapezoidal slot plate 62 does not move; then the second electric cylinder 421 drives the connecting short rod 4274 and then mobilizes the L-shaped rod 4272 to rotate around the rotating axis of the connecting plate 4271, and then the first electric suction cup 4273 is fitted with the inner side of the trapezoidal slot plate 62 (the three first electric suction cups 4273 are respectively fitted with the three surfaces on the inner side of the trapezoidal slot plate 62), and then the first electric suction cup 4273 is energized to suck the inner side of the trapezoidal slot plate 62. The first sliding platform 106 contracts and drives the sucked trapezoidal slot plate 62 to move upward, and then the sliding motor 105 drives the sliding frame 104 and then drives the first sliding platform 106 and the trapezoidal slot plate 62 to move to the middle position of the bottom plate 101, so that the trapezoidal slot plate 62 faces the conveying mechanism 20 on both sides, and the first sliding platform 106 extends to place the trapezoidal slot plate 62 on the table above the bottom plate 101.

[0076] Clamping the trapezoidal end plate 61: Then the second sliding platform 428 is extended to drive the welding mechanism 30 to suck the trapezoidal end plate 61 close to the end plate removal mechanism 40 on the conveying mechanism 20, and the second sliding platform 428 is contracted to drive the trapezoidal end plate 61 to the two ends of the trapezoidal slot plate 62. Due to the existence of the correction plate 107, the end of the correction plate 107 close to the conveying mechanism 20 is folded downward; when the second sliding platform 428 drives the trapezoidal end plate 61, when the trapezoidal end plate 61 passes above the correction plate 107, the correction plate 107 corrects the trapezoidal end plate 61 so that the trapezoidal end plate 61 is aligned with the lower end of the trapezoidal slot plate 62. When the trapezoidal end plate 61 close to the end plate removal mechanism 40 on the conveying mechanism 20 is removed, the transmission motor 203 drives the spacer conveyor belt 202 and then drives the next trapezoidal end plate 61 to the position of the removed trapezoidal end plate 61, so that the next time the end plate removal mechanism 40 takes the trapezoidal end plate 61, it is convenient.

[0077] Weld the trapezoidal end plate 61 and the trapezoidal slot plate 62; the first rodless electric cylinder 312 and the second rodless electric cylinder 314 of the trapezoidal end plate 61 drive the third L-shaped bracket 315 to move forward, backward, left and right; the second servo motor 3171 drives the first gear 3172 to drive the first cross plate 3174 to move up and down; the third servo motor 3178 drives the second gear 3177 to drive the rotating plate 3176 to rotate, and then drives the second connecting mechanism 32 to rotate.

Then the second sliding platform 428 is retracted, and the welding head 33 drives the inner side of the connection between the trapezoidal end plate 61 and the trapezoidal groove plate 62 to be completely welded through the first connecting unit 31 and the second connecting mechanism 32; and then the welding head 33 is driven by the first connecting unit 31 and the second connecting mechanism 32 to perform welding on the outer side of the connection between the trapezoidal end plate 61 and the trapezoidal groove plate 62.
