Device for repairing sunken parts of car metal plate

Abstract

The invention relates to a B25B33 / 00, in particular to a device for repairing sunken parts of a car metal plate. The device comprises a sliding groove plate, a long welding needle, a cylinder body anda handle, the cylinder body is slidably connected to the sliding groove plate, and the long welding needle is sleeved with the inner side of the cylinder body, and a box body is arranged outside theside wall of the cylinder body. The box body is internally provided with a first gear and a second gear which are mutually engaged, a one-way bearing is arranged on the first bearing, and a first gearrack is arranged on the long welding needle and engaged with the first gear. A scale line is arranged at the side edge of one side of the sliding groove plate, a sliding block is arranged on one sideof the sliding groove plate, and a second gear rack is arranged on one side of the sliding block. A detecting head with a scale line is arranged below one side of the sliding groove plate, and a reading plate is arranged on the detecting head. The one-way bearing enables the first gear and the first gear rack to be clamped at the very start to enable the long welding needle and the cylinder bodyto be integrated, the handle is pulled to enable the sunken parts to be restored, then the long welding needle moves back according a set distance, and the problem that in the prior art, the sunken parts of the metal plate are excessively stretched and thus convex hulls are formed is solved.

Description

technical field [0001] The invention relates to the technical field of B25B33 / 00, in particular to a device for repairing sheet metal. Background technique [0002] During the production, assembly and use of the automobile body, the problem of local deformation of the sheet metal often occurs. At this time, the deformation of the sheet metal needs to be repaired, and the deformation of the sheet metal is mostly caused by the depression of the sheet metal. Usually, the process of repairing the dent of the automobile sheet metal is: use the front end of the elongated welding needle connected to the electric welding machine to contact the dent of the car, pass a large current instantly, spot weld the elongated welding needle on the dent of the car, There is a sliding rod type hand hammer on the upper cover, and the long welding needle is driven to move by the backward impact of the hand hammer, so that the long welding needle can pull up the concave position. This method of tri...
