And the chip liquid cleaning and lubricating tool is not added in the design, and fine dust is generated because the rolling processing is implemented by rolling by using a roller. Dust not only affects the surface quality but also accelerates wear of the rolling head. And the piston excircle runout is not checked after the workpiece is clamped, the rejection rate of rolling after the piston is directly clamped is very high, and therefore a novel piston rolling tool is provided, the problems that the rolling force cannot be adjusted when a hob is fed, the hob needs to be frequently replaced corresponding to different products, the surface quality is affected due to the fact that cutting fluid is not added for cleaning and lubricating in the rolling process, the loss of a rolling head is accelerated, the piston excircle runout is not checked, the circular runout after the piston is clamped, the clamping is deviated and the like are solved.
