Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.

As shown in fig. 1 to 5, the valve body grinding machine convenient for collecting grinding chips comprises a base plate 1, a load plate 2 is arranged above the base plate 1, a rotating shaft 3 is mounted on the load plate 2, a driving motor 4 is connected to the top of the rotating shaft 3, a grinding wheel 5 is connected to the bottom of the rotating shaft 3, and an air guide ring 6 fixedly connected to the lower end of the load plate 2 is axially in clearance fit with the rotating shaft 3.

The lower end face of the air guide ring 6 is provided with a ring groove 6a, and the load plate 2 is provided with a fan 7 communicated with the ring groove 6a through a guide pipe.

The bottom ring of wheel 5 is equipped with a plurality of all the time with annular 6a complex chip groove 5a, the bottom of load board 2 is connected with around the collection bits ring 8 of wheel 5 setting of polishing, be fixed with miniature vibrating motor 9 on the collection bits ring 8.
