A driving wheel 37 is rotatably installed on the top plate 301 and the bearing seat 36. The driving wheel 37 is connected to the motor 39 through a belt transmission mechanism 38. The motor 39 is installed on the top plate 301. The lifting platform 8 can support the conical workpiece 5 and detach from the conical workpiece 5 in time so that the conical workpiece 5 can rotate smoothly and automatically under the support and drive of the support member 2 and the driving member 3, so that the measuring member 4 can quickly and accurately detect the runout of the conical workpiece 5, and realize efficient and accurate rolling test. The axis of the bearing 22 and the driving wheel 37 is parallel to the outer side of the conical workpiece 5, and as the driving wheel 37 moves toward the conical workpiece 5, it abuts against the conical workpiece 5. The outer side of the conical workpiece 5 can be supported by the bearing 22 and the driving wheel 37 at three points, so as to stably carry out the rolling test. The number of the tightening cylinders 33 is two and they are symmetrically arranged on both sides of the cross bar 32. The two tightening cylinders 33 can drive the slide 35 to move stably on the guide rail 34. The lifting platform 8 is a plate structure with a smooth surface, and the top surface of the lifting platform 8 is parallel to the bottom surface of the base plate 1. The lifting platform 8 can stably support and lift the conical workpiece 5, so that the conical workpiece 5 can effectively maintain the stability of the position before being clamped by the support member 2 and the driving member 3. The driving pulley in the belt transmission mechanism 38 is installed on the output shaft of the motor 39, and the driven pulley in the belt transmission mechanism 38 is installed on the rotating shaft of the driving wheel 37.

Then, the piston rod of the lifting cylinder 7 is retracted to the end of the stroke, so that the bottom of the conical workpiece 5 is suspended in the air to ensure that the conical workpiece 5 can rotate normally. Then, the motor 39 drives the driving wheel 37 to rotate through the belt transmission mechanism 38, and the rotating driving wheel 37 drives the conical workpiece 5 to rotate. By observing the displacement measurement information of the upper displacement sensor 42 and the lower displacement sensor 43 displayed on the controller 6, it is intuitively judged whether the runout of the conical workpiece 5 is qualified.
