A detection device for valve machining and a detection method thereof

Abstract

The application belongs to the technical field of valve detection, and discloses a detection device for valve machining and a detection method thereof, which comprises a base, a support fixedly arranged on the top of the base, a photosensitive assembly nested on the top surface of the base, and a motor fixedly arranged on the top of the support. The application can adapt to the change of the internal size of the valve to be detected. When the internal diameter of the valve changes, the position of the closely arranged detection assembly changes, thereby changing the position of the corresponding laser emission end. The change of the laser irradiation position is sensed by the photosensitive assembly, the detection of the internal diameter size of the valve is realized, the sensing positions of the standard photosensitive area, the inner photosensitive area and the outer photosensitive area are matched, the size change of the pipe diameter at both ends of the valve is judged, the reduced and expanded areas can be accurately detected, the local size of the inner wall of the valve can be accurately recognized and detected, the quality of the valve can be quickly judged, the detection is simple, and the use effect is good.
