Problems solved by technology

Using a vernier caliper to measure will cause extrusion deformation of the burr, which will affect the accuracy of the inspection. Due to the limitation of the extrusion measurement method, the height of the burr is also difficult to measure accurately, and the shape of the burr cannot be detected, which is not conducive to the research of burr generation.

Abstract

The invention discloses a new type portable detection and identification device and a method for silicon steel sheet burr shape. The device comprises a burr probe device and a burr shape detection device, the burr detection device comprises a probe shell, a control device and a roller device, the burr shape detection device comprises a detection shell, a hand pressing block and an inkpad. The beneficial effects of the invention are that: the burr probe device detects whether a distance is changed through an infrared distance measuring module to judge whether burrs exist or not, the burr shapedetection device prints the shape of burrs through the inkpad to facilitate the follow-up study; the operation is simple, carrying is convenient, and detection efficiency is greatly improved; the inkpad is wrapped with a protective film which is puncture resistant, so that the inkpad can be recycle used.

Description

technical field [0001] The invention relates to a novel portable silicon steel sheet burr shape detection and recognition device and method, and belongs to the technical field of burr shape detection and recognition. Background technique [0002] During the manufacturing process of the transformer core, the edge of the punched silicon steel sheet produces burrs. This kind of burr not only affects the lamination coefficient of the core and reduces the effective cross section, but also easily causes the overlap between the silicon steel sheets of the core, resulting in a short circuit between the sheets, and a sharp increase in eddy current loss. At present, in the core manufacturing process, there are clear control requirements on the control of silicon steel sheet burrs, but the method of detecting burrs has always been using vernier calipers. Using a vernier caliper to measure will cause extrusion deformation of the burr, which affects the accuracy of the inspection. Due t...
