Inner defect detector for annular workpiece

Abstract

The invention discloses an inner defect detector for the annular workpieces, comprising a feeding unit, a host unit, a detecting unit, a discharging unit, a collecting unit and a processing circuit, wherein the feeding unit is fixed on a first door-shaped frame of the host unit, the detecting unit is mounted under the panel of the host unit, the discharging unit and the collecting unit are fixed a second door-shaped frame of the host unit, the processing circuit is mounted on the base. The detector has high automation degree of detection, namely, the detector can automatically discharge, detect, classify and collect the annular workpieces, therefore improving the detecting efficiency and the safety; the detector has wide application scope, namely the detector can detect the inner secret defects for most of complex annular workpieces; the automation streamline detector is adopted, the detecting speed is rapid and the continuous operation is performed; the detecting accuracy is high, the audio frequency detecting method can overcome the defects in the traditional method such as missing detection, false detection and the like.

Description

technical field [0001] The invention relates to a detection device, in particular to a detector for internal defects of an annular workpiece. Background technique [0002] Internal defects of ring workpieces are an important factor affecting the quality of ring workpieces. The existing detection methods for internal defects of annular workpieces mainly include ultrasonic detection method and radiographic detection method. Ultrasonic testing method cannot realize the detection of complex ring-shaped workpieces, and requires experienced inspectors to operate and judge the test results. The radiography inspection method requires multi-angle inspection, and the rays are difficult to penetrate, so internal cracks cannot be effectively detected. At the same time, the efficiency of manual detection is low, there are many interference factors, and there are problems such as false detection and missed detection. Contents of the invention [0003] In view of the shortcomings of t...
