At the same time, , when the crankshaft rod body 5 changes in size, and the crankshaft rod body 5 excessively squeezes the brushing roller 10 during the rotation stroke, the brushing roller 10 can move downward through the extension of the telescopic rod 12, and the extension of the telescopic rod 12 drives the load-bearing network base and the drive The displacement of the roller 11 and the brushing roller 10 can adapt to the brushing processing needs of different rotation diameters. The movement of the screw seat 303 can drive the rotating seat 306 to move from the axis position of the shaft body, and the centering and clamping assembly on one side of the rotating seat 306 can be expanded or reduced. The maximum rotation radius of 6 matches the testing, decontamination and drying of different types of crankshaft rod bodies 5;

When the rotating base 306 can be lifted upward after cleaning, and when the rotating base 306 is rotated to the horizontal direction, the clamped crankshaft rod 5 can be located on the side of the purge pipe 903. At this time, the purging fan 901 can pass to the purge pipe. Air is blown inside 903 and ejected through the purge nozzle 904, and the ejected purge nozzle 904 can purge and remove the cleaning liquid adhered to the surface of the crankshaft rod body 5 to prevent the adhered water liquid from affecting the top laser measurement component 7 measurement accuracy.

The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technical field can, within the technical scope disclosed in the present invention, implement the technical solutions of the present invention. Equivalent substitutions or changes of the inventive concept thereof shall be included in the protection scope of the present invention.
