Supporting device for grinding ceramic elements

Abstract

This invention relates to a supporting device for grinding ceramic element, the supporting device being composed of a plurality of supporting seats installed on the grinding machine, two locating pins deposited on the supporting seats and inserted into two end of the ceramic element to fix it, and a plurality of driving wheels installed on a driving shaft and touching the top of the ceramic element and the locating pins to drive them to rotate simultaneously. The supporting seat have a V-shape locating groove to provide a larger supporting area for supporting the locating pins firmly, further, the locating pins and the ceramic element can be rotated simultaneously so as to prevent the ceramic element and the locating pins from wearing out in the grinding process.

1 . A supporting device for grinding ceramic element which is installed on a grinding machine and comprising: 
 a plurality of supporting seats installed on the grinding machine, the supporting seat being made of high hardness material with low friction factor;    two locating pins positioned on the supporting seats, one end of the locating pin being inserted into one end of the ceramic element to fix it firmly;    a grinding wheel installed under the ceramic element and can be rotated to grind the ceramic element; and    a plurality of driving wheels installed on a driving shaft, the driving wheels touching the top of the ceramic element and the locating pins respectively to drive them to rotate simultaneously.    
   
   
       2 . A supporting device for grinding ceramic element as claimed in  claim 1 , wherein the supporting seat having a V-shape locating groove to provide a larger supporting area for supporting the locating pin firmly.  
   
   
       3 . A supporting device for grinding ceramic element as claimed in  claim 1 , wherein two ends of the ceramic being located with the two locating pins, said ceramic element and two locating pins can be rotated simultaneously by said driving wheels so as to prevent said ceramic element and locating pins from wearing out.
