Detection device for end surface defects of piston pin

Abstract

The invention discloses a detection device for end surface defects of a piston pin. The detection device is provided with two independent detection modules, and the two independent detection modules are used for detecting two end surfaces of the piston pin respectively. The detection device is structurally characterized in that a vertical adjusting pillar is mounted at the top end of a fixed support seat through a plurality of screws and connected with a horizontal adjusting pillar through fixed adjusting blocks, the horizontal adjusting pillar is connected with a mounting plate, the mounting plate is connected with a camera fixing plate through a connecting block, and a lens adjusting block is mounted on the camera fixing plate and connected with a CCD camera through a lens fixing pillar. The end surface defects of the piston pin can be detected, non-contact dynamic detection is realized in a visual identity manner, and the working efficiency is greatly improved while the measurement accuracy is guaranteed.

Description

technical field [0001] The invention is suitable for on-line detection of end surface defects of piston pins of automobile engines, and belongs to the technical field of automatic detection. 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 sampling inspection method. In some factories with high production equipment, advance...

AI Technical Summary

Problems solved by technology

Manual sampling inspection cannot guarantee the accurate measurement of core parameters and the processing quality of parts. At the same time, it will cause manual inspection errors, which cannot meet the high-quality and large-scale requirements

Off-line off-site detection, although the detection accuracy is high, greatly increases the auxiliary time of conveying and clamping, and cannot realize online feedback and control of processing quality
