Surface flaw detection marking apparatus and method for absorber piston rod of automobile shock based on vision

Abstract

The invention discloses a surface flaw detection marking apparatus for an absorber piston rod of an automobile shock based on vision. The apparatus comprises: a frame body; first guide rails, which are symmetrically and vertically arranged on the upper side of the middle part in axial direction on two sides of the frame body; upper and lower sliders, which are symmetrically arranged between the first guide rails, and separately in sliding connection with the adjacent first guide rail; a connecting plate, which is horizontally arranged, and the axial ends of the connecting plate are fixedly connected with the upper and lower sliders; second guide rails, which are arranged on two sides of the bottom surface of the connecting plate in a staggered manner; transverse sliders, which are arrangedon the corresponding second guide rails in an axial sliding manner, and can move axially toward or away from the second guide rails; and clamping rods, which are symmetrically and vertically arrangedon two sides of the connecting plate, and top ends of the clamping rods are fixedly connected with the inner end surfaces of the outer sides of the corresponding transverse sliders. The invention further provides a surface flaw detection marking method for an absorber piston rod of an automobile shock based on vision, which can complete the feeding, vision detection, marking and discharging processes of the absorber piston rod of the automobile shock by machines.

Description

technical field [0001] The invention relates to the technical field of manufacturing and testing of auto parts, and more specifically, the invention relates to a vision-based device and method for detecting and marking defects on the surface of a piston rod of an automobile shock absorber. Background technique [0002] The automobile shock absorber piston rod is an extremely important workpiece in the automobile shock absorber. When it is assembled on the automobile shock absorber, its surface must be smooth and flawless, because once the defective piston rod is installed in the shock absorber , then, in the case of frequent use of the shock absorber, it will accelerate the wear of the piston rod defect, endangering the driving comfort and safety of the car. Therefore, before the piston rod is installed in the shock absorber, it must be ensured that the surface of the piston rod is free from blemishes. [0003] At present, the detection in this field is still in the state o...

AI Technical Summary

Problems solved by technology

[0003] At present, the detection in this field is still in the state of manual detection. After the defects are detected, they will be marked

Since the manual inspection needs to stare at the piston rod for a long time to check, it will cause a series of problems such as visual fatigue, slow detection cycle, high labor cost and low quality of manual inspection.
