本发明提供了一种气缩孔检测装置，包括机架以及相对设置在所述机架上的摄像头与探针，所述探针为中空结构，所述摄像头的拍摄光路朝向所述探针的中空结构；其中，所述探针远离所述摄像头的一端上设有锥形缺口，所述锥形缺口沿所述探针的轴线对称。本发明还提供了一种气缩孔检测方法。本发明技术方案通过利用所述摄像头以及所述探针相互配合的方式采集阀孔内部图像信息，在所述探针上设置一锥形缺口，当摄像头对着所述探针的中空结构中拍照时，所述摄像头的光路则被所述锥形缺口反射到阀孔的内壁上，从而获取到所述阀孔的内壁的图像信息。

The present invention provides a gas shrinkage hole detection device, which includes a frame and a camera and a probe arranged opposite to the frame, the probe is a hollow structure, and the photographing optical path of the camera faces the probe Hollow structure; wherein a tapered notch is provided on one end of the probe away from the camera, and the tapered notch is symmetrical along the axis of the probe. The invention also provides a method for detecting gas shrinkage holes. The technical solution of the present invention collects the image information inside the valve hole by using the camera and the probe to cooperate with each other. A tapered notch is provided on the probe. When the camera faces the hollow structure of the probe, the camera At this time, the light path of the camera is reflected on the inner wall of the valve hole by the tapered notch, thereby obtaining image information of the inner wall of the valve hole.
