Abstract

The invention relates to a visual detection device and method for the outer wall surface of a cylindrical part, and belongs to the technical field of detection devices. The device comprises a workbench component, a displacement control component, a measuring head rotating component, a clamping component and a light supplementing component. The light supplementing component with the lifting light source penetrates through the workbench and the clamping component and is arranged in the cylinder part, and the clamping component is provided with a chuck with a secondary range adjusting function; the displacement control part is provided with a motor position adjusting device, a counterweight unit, a longitudinal secondary position adjusting device and a terminal rotating device; the vision measurement device is arranged at the terminal of the displacement control part. The device can drive the visual measurement device to accurately move to the cylinder part, and the visual detection of the appearance of the cylinder part is completed in cooperation with the rotation of the cylinder part. According to the equipment, through light source optimization, secondary clamping and secondary displacement adjustment, the measurement precision is improved. The device is simple, the method is reliable, and the measurement precision is high.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a visual detection device and detection method for the outer wall of a cylindrical part. Background technique [0002] In the existing inspection of cylindrical parts, after the cylindrical part is vertically fixed on the fixture, semi-automatic equipment is used to detect the size of the through hole in the cylindrical part. The cylindrical parts for industrial applications are usually provided with through holes or other passing structures. For small cylindrical parts, it can be measured manually. For large cylindrical parts, due to the limitation of the measuring range of measuring tools, it is generally operated by manual combined with semi-automatic measuring tools. With this measurement method, it is difficult to realize the measurement of cylindrical parts Accurate measurement of sidewall vias or other structures. [0003] The existing measurement method combin...
