This invention discloses a turning device for square steel used in elevator racks after rolling, belonging to the field of square steel turning technology. It aims to solve problems encountered by existing devices when machining square steel with large aspect ratios and poor rigidity, such as easy vibration in the middle section, interference from positioning and vibration coupling, low centering accuracy, and increased errors due to steel chip jamming. The device includes a turning equipment base, a machine tool guide rail base, a chatter suppression mechanism, a positioning and locking mechanism, and a flexible stabilizing mechanism. The chatter suppression mechanism slides synchronously with the tool holder adjustment table, and adaptively supports the middle section of the square steel through bimetallic strip thermal induction. A displacement sensor detects deformation in real time. The positioning and locking mechanism is linked by an electrical signal, driving the centering component to automatically center via a telescopic rod and gear rack. A metal conductive sheet contacts an electrical contact button to trigger an electromagnet, causing the magnetorheological fluid to harden and lock the ejector pin. The flexible stabilizing mechanism achieves radial stabilization through a triangular turntable and flexible support rollers, and synchronously links with an air duct to blow away steel chips. The three mechanisms work together to form a closed loop, improving machining accuracy and stability, and adapting to the large-scale machining needs of square steel for elevator racks.

This invention relates to the field of image recognition technology, and solves the technical problems of existing technologies that easily misjudge small defects with complex shapes or similar to background textures, and easily lose defect information in the area covered by light spots, leading to missed detections. In particular, it relates to a machine vision-based method and system for quality inspection of industrial parts. The method involves the following steps: acquiring the original image of the target part, performing image preprocessing on the original image to obtain a preprocessed image. This invention uses a one-to-many radial basis kernel function through support vector machine branching, which can effectively characterize the boundary of defect categories under small sample conditions, and can automatically discover complex texture features in defect data. It makes up for the limitations of support vector machines when fitting highly nonlinear distributions, significantly improves the accuracy and robustness of small defect classification, and avoids the failure problem that a single model may fail under specific disturbances.
