Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] as attached figure 1 Shown: a thin steel plate repair welding device, including a high temperature resistant pad 2, a pressing device located on the upper side of the high temperature resistant pad 2, a repair welding positioning device, a welding torch device and a controller 1.
[0018] The pressing device includes a pressing plate 4 with six elastic pressure heads 3 on the lower end surface, a fixing plate 5 positioned on the upper side of the pressing plate 4, four guide posts 10, a cylinder body 61 and a cylinder rod 62 respectively connected with the fixing plate 5 and the pressing plate. 4 screwed cylinder 6; one end of the guide post 10 passes through the pressing plate 4 and is screwed with the fixing plate 5.
[0019] Described welding torch device comprises the three-dimensional numerical control sliding table 7 that is connected with the upper end f...

The invention relates to the field of welding, in particular to a sheet steel welding repair device and a welding repair method. The sheet steel welding repair device comprises a high-temperature-resistant cushion block, a pressing device located on the upper side of the high-temperature-resistant cushion block, a welding repair positioning device, a welding gun device and a controller. When the sheet steel welding repair device is used, a part 11 is placed on the high-temperature-resistant cushion block and is fixed through the pressing device, the welding repair positioning device detects and determines a position needing welding repair, and the welding gun device is controlled by the controller to carry out welding repair on the position needing welding repair. Due to blocking and timely heat transferring of the high-temperature-resistant cushion block, the situations that the part 11 is heated and deformed and weld beading occurs are avoided, heated deformation of the part 11 undergoing welding repair is little, welding repair quality is good and the sheet steel welding repair device is suitable for welding repair positions of various sizes.
Description
technical field [0001] The invention relates to the welding field, in particular to a thin steel plate repair welding device and a repair welding method. Background technique [0002] Since the thickness of the automobile body steel plate is generally 0.7-3.0mm, the parts are easy to crack during stamping and stretching, and the solder joints are easy to explode and weld through during spot welding. During spot welding, the solder joints are exploded and the welding penetration is repaired; these thin steel plate parts are easy to be heated and deformed and the parts are burned through during repair welding, and the weld bumps are larger after repair welding; the utility model of Chinese patent announcement No. CN 202062154U is disclosed A special tool for repairing holes in thin plate welding, which is composed of a contact head, a connecting rod, and a handle. One end of the contact head is fixedly connected to the connecting rod, and the other end of the connecting rod is...
