Buffing disc for cleaning hubs

Abstract

Buffing disc for cleaning hubs, including a seat body and a grinding plate body. The seat body has a connecting end face with a predetermined area. A shaft chamber inward extends from a center of the connecting end face by a predetermined depth to form an opening on the connecting end face. The grinding body is disposed on the connecting end face around the opening of the shaft chamber.

What is claimed is:  
     
         1 . Buffing disc for cleaning hubs, comprising: 
 a seat body having a connecting end face with a predetermined area, a shaft chamber inward extending from a center of the connecting end face by a predetermined depth to form an opening on the connecting end face; and    a grinding body disposed on the connecting end face around the opening of the shaft chamber.    
     
     
         2 . Buffing disc for cleaning hubs as claimed in  claim 1 , further comprising a pair of attachable plates which can be repeatedly attached to each other, the attachable plates being respectively disposed on the connecting end face and one face of the grinding body opposite to the connecting end face.  
     
     
         3 . Buffing disc for cleaning hubs as claimed in  claim 1 , wherein the grinding body is an annular body formed with a central hole communicating with the opening of the shaft chamber.  
     
     
         4 . Buffing disc for cleaning hubs as claimed in  claim 3 , wherein the grinding body includes an annular substrate and an annular buffing plate with a predetermined thickness, one face of the substrate being connected with the connecting end face, the buffing plate being attached to the other face of the substrate.  
     
     
         5 . Buffing disc for cleaning hubs as claimed in  claim 4 , wherein the seat body includes an annular stop wall outward extending from the circumference of the connecting end face, the stop wall defining a receiving space for accommodating the substrate therein.  
     
     
         6 . Buffing disc for cleaning hubs as claimed in  claim 4 , wherein the grinding body further includes an annular pad body with a predetermined thickness, the pad body being disposed between the substrate and the connecting end face.  
     
     
         7 . Buffing disc for cleaning hubs as claimed in  claim 4 , wherein the grinding body has a buffing plane face on one face of the buffing plate opposite to the substrate.  
     
     
         8 . Buffing disc for cleaning hubs as claimed in  claim 7 , wherein the grinding body has at least one chip-expelling notch formed on outer circumference of the buffing plate.  
     
     
         9 . Buffing disc for cleaning hubs as claimed in  claim 4 , wherein the grinding body further includes an annular buffing face formed on inner circumference of the buffing plate.  
     
     
         10 . Buffing disc for cleaning hubs as claimed in  claim 1 , wherein the seat body has multiple inclined grooves formed on a wall of the shaft chamber and inward extending from the circumference of the opening, the depths of the inclined grooves being gradually reduced.  
     
     
         11 . Buffing disc for cleaning hubs as claimed in  claim 10 , wherein the seat body has several ribs defined between adjacent inclined grooves.  
     
     
         12 . Buffing disc for cleaning hubs as claimed in  claim 10  or  11 , wherein open ends of the inclined grooves are formed on the connecting end face and covered by the grinding body.  
     
     
         13 . Buffing disc for cleaning hubs as claimed in  claim 1 , wherein the seat body further include a holder section, a dome section being engaged with one end of the holder section, whereby the shaft chamber inward extends from the open end of the holder section into the dome section.  
     
     
         14 . Buffing disc for cleaning hubs as claimed in  claim 13 , wherein an extension sleeve with a certain length is connected between the holder section and the dome section, two ends of the extension sleeve being respectively engaged with the holder section and the dome section.  
     
     
         15 . Buffing disc for cleaning hubs as claimed in  claim 1 , wherein the seat body further includes a transmission shaft fixedly disposed on the other end of the seat body opposite to the connecting end face.
