Embodiment 1

[0051] refer to figure 1 , a welding method for repairing gaps in sheet metal bends, comprising the following steps:

[0052] B1: Keep one side of the large sheet metal part and the small sheet metal part placed vertically, fix the large sheet metal part, and move the small sheet metal part to the gap of the large sheet metal part;

[0053] B2: Use a horizontal welding torch to spot weld the connection line between the vertical surface of the large sheet metal part and the small sheet metal part;

[0054] B3: Adjust the position of the large sheet metal part and the small sheet metal part so that the other side of the large sheet metal part and the small sheet metal part is placed horizontally;

[0055] B4: Use a vertical welding torch to spot-weld the horizontal connecting lines of large sheet metal parts and small sheet metal parts to obtain repaired large sheet metal parts after welding;

[0056] B5: Grinding the weld seam of large sheet metal parts after welding.

[005...

Embodiment 2

[0059] refer to image 3 The welding device in this embodiment is used for welding small sheet metal parts with gaps, and includes a base 1, a vertical column 2 and a beam 3, and the base 1, the vertical column 2 and the beam 3 form a space in which a welding assembly is arranged, so The welding assembly includes installing a vertical welding torch 42, a horizontal welding torch 72, a suction nozzle 8 for absorbing small sheet metal parts 13, a horizontal fixing seat and a vertical fixing seat 11 for fixing large sheet metal parts.

[0060] Specifically, the vertical welding torch 42, the horizontal welding torch 72 and the suction nozzle 8 are all installed on the horizontal mounting bracket 4, and the horizontal mounting bracket 4 is located below the crossbeam 3, and a chute in the X-axis direction is set on the crossbeam 3, The chute is provided with a Y-axis direction sliding rod, and the Y-axis direction sliding rod is provided with a lift cylinder 5 that is slidably con...

Embodiment 3

[0076] refer to Figure 7 and Figure 8 , the upper end of each set of clamping blocks 113 in this embodiment is provided with handles 1111, the two ends of the handles 1111 are respectively hinged to the upper ends of the connecting rods 1110, and the lower ends of each of the connecting rods 1110 are respectively hinged to different clamping Block 113, press the handle 1110, the spring 114 can be compressed, and the two clamping blocks 113 are far away, so that the vertical side 122 of the large sheet metal plate 12 can be conveniently put in and taken out between the clamping blocks 113.

Abstract

The invention discloses a welding method, a welding device and a weld grinding device for repairing a sheet metal bend. The welding method for repairing a gap in a sheet metal includes the following steps. Then the vertical surface welding and horizontal surface welding of the large sheet metal parts are carried out in turn respectively, and finally the weld seam of the large sheet metal parts after welding is polished. Each side is welded separately, which is convenient for processing control, and the repair process is simple and efficient; the positions of the tooling and welding torch in the welding device can be changed, and with the conversion of the fixed orientation of the large sheet metal part, the gap of the large sheet metal part can be repaired efficiently. , the follow-up grinding device can grind the two surfaces of the bending place separately according to the bending angle, each grinding machine is equipped with long and short grinding rods for grinding respectively, and the grinding efficiency is high.

Description

technical field [0001] The invention relates to the technical field of sheet metal repair, in particular to a welding method, a welding device and a weld seam grinding device for repairing gaps in sheet metal bends. Background technique [0002] Present sheet metal repairing devices, such as the sheet metal repairing devices disclosed in patents CN110918689A, CN102921772A, CN110252854A, and CN107457284A, can accurately and effectively locate and operate to repair dents or deformations in the panel through a simple structure. However, these sheet metal repair devices cannot weld small metal sheets to large metal sheets, so as to repair the gaps of large metal sheets. Patent CN110315236A discloses a sheet metal repair device, which is used for welding small metal sheets to large metal sheets, but it is generally suitable for welding flat sheet metal parts, and many sheet metal parts are bent parts. For metal parts, the above-mentioned sheet metal repair device cannot be repai...
