Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to an external corner welding auxiliary tooling. Background Art

[0002] Welding is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials. In some welding processes, workers are required to hold a welding gun to weld the weld. For example, in the preparation process of the oven, when welding the return air duct workpiece, workers are required to hold the welding gun and deflect and twist it at a specific angle for welding. On the one hand, it is difficult for workers to accurately control the angle based on experience alone. On the other hand, the welding distance is long, and it is difficult for workers to maintain the same angle for a long time. This can easily lead to poor welds, thus affecting the welding effect and appearance. Utility Model Content

[0029] Example

[0030] Reference Figure 1 As shown, this embodiment provides an external corner welding auxiliary tooling, which includes a collar 2 and a moving part. The collar 2 is fixed to a position of a welding gun 1 close to a welding head, and the position and welding angle of the welding gun 1 can be changed by changing the position and angle of the collar 2.

[0031] Specifically, refer to Figure 2 As shown, the moving member includes a bracket 3, a first rolling member 4 and a second rolling member 5. The bracket 3 includes a main frame 31, a first adjustment plate 32 and a second adjustment plate 33; the collar 2 is connected to the main frame 31 so that the collar 2 moves with the main frame 31. The first adjustment plate 32 is rotatably connected to the main frame 31 around a first axis, and the second adjustment plate 33 is rotatably connected to the main frame 31 around a second axis; when in use, the first rotation axis and the second rotation axis are kept in line, and the welding angle of the welding gun 1 is adjusted by adjusting the angle between the main frame 31 and the adjustment plate. The first rolling member 4 is connected to the first adjustment plate 32, and the second rolling member 5 is connected to the second adjustment plate 33, and the rolling axis of the first rolling member 4 intersects with the rolling axis of the second rolling member 5.

[0032] The present embodiment provides an external corner welding auxiliary tooling, which utilizes a first rolling member 4 and a second rolling member 5 to respectively abut against two sides of a part 6 to be welded, so that a worker can maintain a fixed weld bead while holding a welding gun 1 for welding; and the welding angle of the welding gun 1 can be adjusted by adjusting the angle between the main frame 31 and the adjustment plate, so that an accurate angle can be maintained during the welding process, thereby improving the welding quality and aesthetics.

[0033] Specifically, refer to Figure 4 As shown, the first rolling member 4 abuts against the first side 61 of the part 6 to be welded, and the second rolling member 5 abuts against the second side 62 of the part 6 to be welded, and the first side 61 and the second side 62 are respectively located on both sides of the weld. The first rolling member 4 abuts against the first side 61 of the part 6 to be welded, and the second rolling member 5 abuts against the second side 62 of the part 6 to be welded, so as to position the welding gun 1. When using it, the worker only needs to ensure that the rolling member fits the part 6 to be welded to ensure the accuracy of the weld.

[0034] Specifically, the rolling axis of the first rolling element 4 intersects with the rolling axis of the second rolling element 5 to form a first angle; the first side 61 and the second side 62 intersect to form a second angle; the first angle is equal to the second angle. In this embodiment, since the second angle between the first side 61 and the second side 62 of the part 6 to be welded is 90°, the first angle is also 90°; in other embodiments, if the angle between the first side 61 and the second side 62 of the part 6 to be welded is other angles, the first angle can also be made to be a corresponding angle by changing the shape of the adjustment plate to ensure that the first rolling element 4 abuts against the first side 61 of the part 6 to be welded, and the second rolling element 5 abuts against the second side 62 of the part 6 to be welded.

[0035] Specifically, combined Figures 1 to 3 As shown, the main frame 3 includes a main board 311, a first side plate 312 and a second side plate 313; the first side plate 312 and the second side plate 313 are respectively connected to the two sides of the main board 311, so that the first side plate 312 and the second side plate 313 are parallel to each other. The first side plate 312 is provided with a first hole, the first adjustment plate 32 is provided with a second hole 316, and the first bolt 314 is connected to the first nut after passing through the first hole and the second hole 316 respectively; the second side plate 313 is provided with a third hole, the second adjustment plate 33 is provided with a fourth hole, and the second bolt 315 is connected to the second nut after passing through the third hole and the fourth hole respectively. When the first nut and the second nut are loosened, the angle between the main frame 3 and the adjustment plate can be adjusted, thereby adjusting the welding angle of the welding gun 1, and when the first nut and the second nut are tightened, the welding angle of the welding gun 1 can be fixed.

[0036] Reference Figure 1As shown, the second hole 316 and the fourth hole are respectively in the shape of long strips, so that the relative heights of the main board 311 and the first side board 312 and the second side board 313 are adjustable. Figure 3 As shown, the main board 311 is provided with a long strip adjustment hole 317, and the screw 318 passes through the adjustment hole 317 to lock the main board 311 and the collar 2. The height position and horizontal position of the welding gun 1 can be adjusted so that the rolling element can respectively abut against the side of the part to be welded 6 at the best welding angle and position to ensure positioning.

[0037] Specifically, the first rolling element 4 and the second rolling element 5 can be selected from any one of a bearing, a roller, and a ball. In this embodiment, a bearing is preferred.

[0038] Usage process: After the worker holds the welding gun 1, he adjusts the angle between the main frame 3 and the adjustment plate according to the optimal welding angle, and then adjusts the height and horizontal position of the welding gun 1 so that the first rolling member 4 abuts against the first side 61 of the part 6 to be welded, and the second rolling member 5 abuts against the second side 62 of the part 6 to be welded. After tightening the screw 318, the first bolt 314 and the second bolt 315, the welding gun 1 is moved along the weld direction to perform welding operations.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
