Effective measurement device for precision adjustment and control of welded vehicle body

Abstract

The invention discloses an effective measurement device for precision adjustment and control of a welded vehicle body. The device comprises a measuring reference base plate, a measuring base worktable, a left overturning table measuring plate, an auxiliary measuring crossbeam and a right overturning table measuring plate. The measuring base worktable is arranged above the measuring reference baseplate. Four corners of the measuring reference base plate are provided with four reference holes. Four reference holes of the measuring reference base plate are aligned with the reference holes of a clamp reference plate, the measuring reference base plate is fixedly connected with the clamp reference plate. The measuring base worktable is fixedly connected with the measuring reference base platethrough screws. The left overturning table measuring plate and the right overturning table measuring plate are fixedly connected with a clamp overturning table through screw holes arranged on the leftoverturning table measuring plate and the right overturning table measuring plate. The auxiliary measuring crossbeam is fixedly connected with the left overturning table measuring plate and the rightoverturning table measuring plate through elongated holes arranged at two ends of the auxiliary measuring crossbeam.

Description

Technical field: [0001] The invention relates to an effective measuring device for precision adjustment and control of a welded vehicle body. Background technique: [0002] Existing bus body precision control technology, in addition to the accuracy of sheet metal parts, basically only uses welding molds to control the precision of the body during the tailor welding process of major assemblies, mainly through positioning pins and positioning blocks. In the modulation process, the trial assembly method is mostly used for repeated debugging, and finally the accuracy of the body is guaranteed. Because of the lack of effective measurement data to support the debugging of the accuracy of the body, the stability and consistency of the body are always difficult to guarantee. In the prior art, [0003] Compared with passenger cars, the bus body has a large body size, and the stamping parts are not complete process parts, so the precision of the stamping parts is low, the number of w...

AI Technical Summary

Problems solved by technology

[0003] Compared with passenger cars, the bus body has a large body size, and the stamping parts are not complete process parts, so the precision of the stamping parts is low, the number of welding molds is small, the body data, parts and component assembly measurement data are less, and it is also difficult to measure Large, low measurement accuracy, low measurement efficiency, high measurement cost

Due to the large size of the bus body, the measurement range of calipers and height rulers is not enough, even the portable three-coordinate measurement range cannot meet the needs of the body and fixture positioning point measurement
