Problems solved by technology
[0004] The defect of above-mentioned repairing method is: (1) the required operation space of repairing tool is larger
(2) Since the inner surface of the installation hole cannot be completely repaired, the outer surface must be polished, and the thickness of the iron sheet after grinding is reduced, which greatly reduces the repair quality
(3) Due to the collision between the anvil and the outer surface of the installation hole during the process of knocking the installation hole, the paint on the outer surface of the installation hole will be separated, so it needs to be repainted, which increases the repair process, and the paint is easily damaged after repair
The above method generally has the problems of complex repair process, long working hours and high cost

Description
technical field [0001] The invention relates to a repairing device and method for deformed holes on sheet metal parts, in particular to a repairing device and method for mounting holes with simple repairing process, short working hours and low cost. Background technique [0002] There are many mounting holes on sheet metal parts, and the mounting holes are prone to deformation during the production process. The main reasons for the deformation of the mounting hole are: (1) during handling; (2) improper operation of the workers; (3) defects in the sheet metal itself when repairing the outer surface of the sheet metal part. Because when repairing the outer surface of the sheet metal part, the installation hole becomes the fulcrum of the leverage force of the repair tool. Under the action of the lever force, the mounting hole cannot provide a large enough reaction force, resulting in varying degrees of deformation of the iron sheet around the mounting hole. [0003] The defor...
