Description

technical field [0001] The invention relates to a detection and precise positioning device and detection method for a longitudinal beam of an automobile frame, which are applied to the detection of a large-size flat piece. Background technique [0002] There are more than 200 holes that need to be processed on the longitudinal beam of the automobile frame. In the process of processing, the quality defects of incomplete hole processing often occur due to punches, drills broken or processing omissions. The frame longitudinal beams with the above-mentioned quality defects enter the production and assembly process, which will seriously affect the normal production order, disrupt the rhythm of the production process, and cause great economic losses to the enterprise. [0003] Since the positions of the holes on the longitudinal beams of automobile frames have no obvious distribution rules, the methods of detecting the number of target holes such as photoelectric sensors or magne...
