Abstract

The invention discloses a straightness detection device for a busbar in a small-diameter tubular workpiece, which includes a guide rod, the guide rod is provided with grooves along the axial direction, and the two side walls of the groove are provided with sliding grooves parallel to each other. Equipped with a roller, the roller driving device is fixedly connected to the guide rod, and the roller driving device drives the roller to roll along the chute. Extending out of the groove, one end of the connecting rod is rigidly connected with a detection device capable of detecting the straightness of the inner bus bar of the tubular workpiece, which has the characteristics of high applicability.

Description

technical field [0001] The invention belongs to the technical field of tubular workpiece detection, and relates to a straightness detection device for a busbar in a small-diameter tubular workpiece. Background technique [0002] With the continuous development and application of tubular workpiece detection technology, the research of tubular workpiece detection system has attracted more and more attention and attention, and tubular workpieces have a large number of applications in military or industrial production, especially the small diameter tubular workpieces. The application is more and more extensive, such as artillery barrel, transportation pipe and so on. However, for the inner surface generatrix (plain line) of these tubular workpieces, its straightness is not only difficult to guarantee relative to the straightness of the outer surface generatrix, but also inconvenient to detect due to the limitations of the small-diameter tube itself, but in terms of use, small T...
