The variable distance mechanism 74 is installed on the connecting block 71. A bracket slider 75 is provided between the variable distance mechanism 74 and the camera bracket 72. Two sets of detection camera assemblies 7 are provided on the connecting block 71. Because there are various cylinder blocks in actual production, and the cylinder bore center distances and cylinder bore lengths of cylinder blocks of different models are different. At this time, the center distance between the two cameras can be automatically adjusted through the variable distance mechanism, and the detection of cylinder blocks of multiple models can be realized. The camera used is a 2D camera.
