Automated detection method and device for face difference and gap of automobile large sheet metal parts

Abstract

The invention relates to the field of automobile manufacturing and measurement, in particular to an automated detection method and device for the face difference and gap of automobile large sheet metal parts. The automated detection device comprises a cylindrical PVC initial location and translation detection motion module, a spinning detection motion module, a contacting displacement sensor, a dynamic compression mechanism, a positioning support mechanism, a position determination electromagnetic switch, a baseboard, a measurement control module and a data processing module. According to theautomated detection method and device for the face difference and gap of the automobile large sheet metal parts, one-time automated detection of multiple measuring points can be realized, and the problem of meter operation by personnel in difficult detection area is solved through automated detection. Detection data are uploaded to an upper computer to display and analyze the quality situation immediately, a production process is adjusted in time, the data are uploaded directly, and thus possible omission in the traditional meter reading process is avoided.

Description

technical field [0001] The invention relates to the field of automobile manufacturing and measurement, in particular to an automatic detection method and device for surface differences and gaps of large sheet metal parts of automobiles. Background technique [0002] In the existing automobile production, the surface difference and clearance detection of large-scale sheet metal parts of automobiles mostly adopts the detection method of surface imitation and manual metering, but many detection positions in large-scale sheet metal parts are difficult to detect, and some parts are located at the bottom , It is inconvenient to operate manually, which consumes man-hours of testing, resulting in a lot of labor and time costs. Large parts such as car sunroofs generally require two to three workers, and the operation takes more than 10 minutes to complete the inspection. In addition, manual recording of inspection data is often used, which causes difficulties in transmission and data...
