() I (1) (2) (3) (4) (5) (6) (7) I Abstract The structure is mainly composed of a motor, frame, transmission belt, reducer, screw, chuck. Produced by the motor power through a belt wheel speed reducer will need to transfer the power to the belt wheel, belt wheel drives the gear, the power output to the chuck and screw speed reducer to drive the movement of the above, the whole device Abstract this thesis research: (1) the overall structure design of small diameter steel pipe ultrasonic flaw detection mechanism. (2) performance analysis of small diameter steel pipe ultrasonic flaw detection mechanism. (3) the choice of motor. (4) transmission system, execution unit and frame design for small diameter steel pipe ultrasonic flaw detection mechanism. (5) the design of components for the design calculation and check. (6) the use of computer aided design, 3D modeling on Design of parts. (7) to draw the assembly drawing and parts assembly diagram and parts diagram design.
