The second driving wheel 9 and the fourth driving wheel 25 are mounted on the second rotating shaft 7, and the first driving wheel 5 and the third driving wheel 24 are mounted on the first rotating shaft 4. The grooved coupling 6 connects the first rotating shaft 4 and the second rotating shaft 7. After the driving wheel and the driven wheel are connected by the rotating shaft and the grooved coupling 6, they are fixed to the base frame 3 by connecting screws (connecting screw A10, connecting screw B12, connecting screw C13, connecting screw D16, and connecting screw E20). The first driven wheel 2, the second driven wheel 22, the third driven wheel 23, and the fourth driven wheel 12 are wrapped in rubber and are located on the opposite sides of the third driving wheel 24, the first driving wheel 5, the fourth driving wheel 25, and the second driving wheel 9, respectively. The bar to be inspected is placed between the driving wheels 5, 9, 24, 25 and the driven wheels 2, 22, 23, 12.

[0025] The first driving wheel 5, the second driving wheel 9, the third driving wheel 24, and the fourth driving wheel 25 are fixed on the base frame 3. The speed-regulating motor 8 drives the synchronous belt pulley 19 to rotate, which in turn drives the first rotating shaft 4 to rotate, thereby enabling the first driving wheel 5, the second driving wheel 9, the third driving wheel 24, and the fourth driving wheel 25 to rotate, thus realizing the rotation of the bar placed between the first driving wheel 5, the second driving wheel 9, the third driving wheel 24, the fourth driving wheel 25 and the first driven wheel 2, the second driven wheel 22, the third driven wheel 23, and the fourth driven wheel 12.

The base frame 3 has four adjustment blocks 1 at its four support corners. When the ground is uneven, the adjustment blocks 1 can be used to level the base frame 3, ensuring the bar can rotate smoothly. The length units in the diagram are mm.

[0029] This invention is applicable to small-diameter bars of various specifications, is simple and convenient to operate, and can effectively improve testing efficiency and quality.

Place the bar being inspected between the driving and driven wheels, turn on the power switch, and adjust the speed control motor 8 to a suitable setting to ensure the bar's rotation speed meets the requirements. After the bar has rotated smoothly, evenly apply the coupling agent to the surface of the bar before performing ultrasonic testing. After the test is completed, turn off the speed control motor and the power switch, and remove the bar being inspected.
