[0023] As a preferred embodiment of the present invention, the clamping transmission mechanism includes a cylinder 4, a worm 11, a Z-axis motor 12, a scanning axial pressure wheel 13, a scanning axial driving wheel 14, a No. 3 spur gear 15 and a pressure wheel slider spring 16. The scanning drive seat 5 is respectively equipped with a scanning axial pressure wheel 13 and a scanning axial driving wheel 14. The scanning axial pressure wheel 13 and the scanning axial driving wheel 14 are respectively arranged on both sides of the sleeve 6. The scanning axial pressure wheel 13 and the scanning axial driving wheel 14 are used to cooperate in clamping the sleeve 6 and driving it to move. The number of the scanning axial pressure wheel 13 and the scanning axial driving wheel 14 is not limited, and an appropriate number can be arranged; a cylinder 4 is fixedly installed on one side of the scanning drive seat 5, and a pressure wheel slider spring 16 is fixedly installed on the output end of the cylinder 4. The scanning axial pressure wheel 13 is rotatably installed on the pressure wheel slider spring 16, and the cylinder 4 is used to drive the scanning axial pressure wheel The wheel 13 moves relative to the scanning axial drive wheel 14; a Z-axis motor 12 is installed and fixed on the side of the scanning drive seat 5 away from the cylinder 4, and the wheel axle of the scanning axial drive wheel 14 is rotatably connected to the scanning drive seat 5. A worm gear (not shown) is also installed and fixed on the wheel axle of the scanning axial drive wheel 14, and the worm 11 is meshingly connected with the worm gear. A No. 3 spur gear 15 is respectively installed at the output end of the worm 11 and the Z-axis motor 12, and the two No. 3 spur gears 15 are meshingly connected; during operation, the worm 11 can be driven to rotate by the Z-axis motor 12, thereby achieving the purpose of driving the scanning axial drive wheel 14 to rotate, and the sleeve 6 can be driven to move; the scanning axial pressure wheel 13 can be driven by the cylinder 4 to move relative to the scanning axial drive wheel 14, and the scanning axial pressure wheel 13 and the scanning axial drive wheel 14 cooperate to achieve the purpose of controlling and clamping the sleeve 6, thereby realizing the integration of each movement process.

[0024] In one embodiment, bearing seats (not shown) are rotatably mounted at both ends of the worm 11 , and the bearing seats are fixed on the scanning drive seat 5 , so as to improve the rotation stability of the worm 11 .

[0025] In one embodiment, a flexible shaft (not shown) is further provided on the inner side of the sleeve 6 , and the end of the flexible shaft is used to connect to a probe or other device, which is not limited.

[0026] In one embodiment, a cover plate is also installed on the scanning drive seat 5. The cover plate protects the internal structure and can effectively prevent most dust particles from entering, thereby ensuring the safety and accuracy of the operation of the mechanism.

[0027] The specific working process is as follows:

[0028] 1) Under the action of the X-axis motor 10, the second spur gear 9 is driven to rotate, so that the scanning trolley 3 moves along the slide rail. When the scanning trolley 3 moves below the bolt hole, the X-axis motor 10 stops running;

[0029] 2) Start the automatic centering process of the probe: two cameras (not shown) installed in the X and Y directions of the scanning center capture the image of the pipe mouth to be tested in real time, and obtain the current center data through image pattern recognition and position detection, and use the obtained center deviation data to control the X and Y axis drivers on the carrier platform to make the scanner move accurately. The movement process is as follows: the X-axis motor 10 restarts, so that the position error of the scanning trolley 3 in the X-axis direction reaches a predetermined value, and the X-axis motor 10 stops running; the No. 1 spur gear 2 is connected to a rotating motor, and the rotating motor starts, driving the No. 1 spur gear 2 to rotate, thereby driving the arc gear 8 to rotate, so that the scanning drive seat 5 rotates around the connecting shaft 7. When the error in the Y-axis direction reaches a predetermined value, the rotating motor stops running, and the pipe mouth alignment operation is completed at this time;

[0030] 3) The cylinder 4 is started, driving the pressure wheel slider spring 16 to move toward the scanning axial drive wheel 14. Since the pressure wheel slider spring 16 is connected to the scanning axial pressure wheel 13, the scanning axial pressure wheel 13 moves toward the scanning axial drive wheel 14, so that the sleeve 6 between them is compressed, and the cylinder 4 stops running;

[0031] 4) After clamping, the Z-axis motor 12 is powered on to drive the second and third spur gears 15 to rotate, thereby rotating the worm 11, driving the scanning axial drive wheel 14 to rotate, and causing the sleeve 6 to rise slowly.

[0032] The mobile trolley for main pump connection bolt inspection is mainly used in the quality inspection process of large-size bolts. It can realize movement in three directions of X-axis, Y-axis and Z-axis, and can adjust the corresponding angles in real time, thereby improving the efficiency and accuracy of bolt inspection, saving manpower and space, and having a high degree of automation to maximize production benefits.

[0033] In addition, there are no specific restrictions on the control, model and circuit connection of each component, and they can be flexibly set in actual application.

[0034] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.
