Abstract

The invention provides a detection device for piston pin outer circle defects. The detection device is structurally characterized in that supporting columns and an installing beam are fixed through bolts, fixing plates are arranged on the installing beam, adjusting columns are fixed to the installing beam through the fixing plates, a camera fixing plate and a light source fixing plate are fixed to the corresponding adjusting column, a light source is installed on each light source fixing plate through bolts, a line scanning camera is installed on each camera fixing plate through bolts, and the light sources and the line scanning cameras are located over rolling wheel V-type bases; the rolling wheel V-type bases are installed on a bottom plate, in-place sensors are located below the rolling wheel V-type bases and installed on the bottom plate, and the rolling wheel V-type bases are connected through rolling wheel driving shafts; rolling wheels are arranged on the rolling wheel V-type bases, a rolling rotation driving device is arranged at one side of each rolling wheel, and a shading piece is arranged at the other side of each rolling wheel. The detection device can detect the piston pin outer circle defects, visual recognition is adopted, non-contact dynamic detection is achieved, and the working efficiency is greatly improved while measurement accuracy is ensured.

Description

technical field [0001] The invention is suitable for on-line detection of outer circle defects of automobile engine piston pins, belongs to the technical field of automatic detection, and specifically relates to a detection device for outer circle defects of piston pins. Background technique [0002] With the rapid development of modern industrial automation technology, detection technology is rapidly developing in the direction of digitization and automation. The rapid development and deep integration of manufacturing and information technology such as precision manufacturing technology, sensor technology, Internet of Things technology, and big data analysis have promoted the continuous development of detection technology. change. At present, the manufacture of piston pins has achieved automatic production, but the automation level of the matching piston pin detection is relatively low. The inspection process of most domestic manufacturers is still stuck in the manual samp...
