Automatic detection device for welding seam of high-pressure vessel

The utility model relates to the technical field of welding seam detection of high-pressure containers, in particular to an automatic detection device for welding seams of high-pressure containers, which comprises a liftable frame, a motor is fixedly connected onto the surface of the liftable frame, an output shaft is arranged on the surface of the motor, a turntable is fixedly connected onto the output shaft of the motor, and the turntable is provided with a rotating shaft. The motor drives a rotary table to rotate through an output shaft, the surface of the rotary table is fixedly connected with a guide rod, the surface of the guide rod is slidably connected with a sliding rod, and the surface of the rotary table is fixedly connected with a first air cylinder. The detection head is driven by the motor and the turntable to move in a zigzag manner, so that the detection block performs detection on the high-pressure container, the position of the detection head can be adjusted through the first air cylinder, a
