Embodiment
Embodiments of the present invention is further illustrated below in conjunction with the accompanying drawings：
As shown in the figure, a kind of valve body core radius variable grinding attachment, it includes rotating disk 1, drives 1 rotation of rotating disk
Dynamical element 2 and the sharpening 3 that several deciles are uniformly distributed and slip is in the rotating disk 1, the rotating disk 1 include
The chassis 4 being connected with the dynamical element 2 and the lid 5 for 3 installations of whetting a knife, the chassis 4 is fixedly connected with lid 5
And cooperatively form cavity and cavity inside and be equipped with while adjust distances between all sharpenings 3 and 1 center of circle of the rotating disk
Adjusting mechanism, the product on surface can be easily removed by the present invention very much, can improve the circularity on core surface, Ke Yiti
High ball wicking surface smoothness, makes valve body and core assembly precision be guaranteed；In addition, by adjusting mechanism adjust it is all sharpening with
Distance between the rotating disk center of circle, can make the present invention be applicable in the core of more sizes, have practicality height, simple in structure, use
The advantages of facilitating.
The lid 5 be equipped with for it is described whet a knife 3 do it is centripetal linear motion or centrifugation linear motion and it is elongated
