Coaxiality detection machine device for petroleum drill rod

The invention belongs to the technical field of coaxiality detection, and relates to a petroleum drill rod coaxiality detector device, which comprises two side frames and a control panel, and further comprises a first air cylinder, a sliding plate, an electric push rod, an automatic clamping mechanism and a driving mechanism, the two side frames are connected with sliding plates in a sliding mode, first air cylinders are installed on the side frames, telescopic rods of the first air cylinders are connected with the sliding frames, electric push rods are installed on the sliding plates, automatic clamping mechanisms used for clamping the petroleum drill rod are arranged on the first air cylinders, and driving mechanisms are arranged on the side frames. And a detection mechanism is arranged on the driving mechanism. When the petroleum drill rod is detected, the detection shaft used for detection can move along the whole petroleum drill rod to detect the petroleum drill rod, the detection process is more compreh
