Stone edge grinding machine

Abstract

The present utility model relates to a stone edge grinding machine, including a bearing frame, a rocker arm system and a grinding wheel system, wherein: the said bearing frame comprises a base plate, a shaft fixed on the center of the base plate, a workbench connected fixedly to the top end of the shaft and a bracket mounted above the workbench in an order from bottom to top; the big end of rocker arm at one end of the said rocker arm system is sleeved rotatably on the shaft by a bearing, and the other end of the rocker arm system is joined with the grinding wheel system; the said grinding wheel system includes a grinding wheel and an electric motor with the grinding wheel mounted thereon. The said grinding wheel system further comprises a center idler wheel which is mounted coaxially above the grinding wheel. Side idler wheels are mounted along the outer flank of the grinding wheel in a horizontal plane. The present utility model has a simple structure, great convenience in operation and high processing precision. It can perform an all-periphery operation for processing 360° of the circumferential perimeter of plate stock and a template can be used in the processing.

1 . A stone edge grinding machine, including a bearing frame, a rocker arm system and a grinding wheel system, wherein:
 the said bearing frame comprises a base plate, a shaft fixed on the center of the base plate, a workbench connected fixedly to the top end of the shaft and a bracket mounted above the workbench in an order from bottom to top;   one big end of the rocker arm at one end of the said rocker arm system is sleeved rotatably on the shaft by a bearing, and the other end of the rocker arm system is joined with the grinding wheel system.   The said grinding wheel system includes a grinding wheel and an electric motor with the grinding wheel mounted thereon.   
   
   
       2 . The stone edge grinding machine according to  claim 1 , wherein: the said electric motor with a grinding wheel mounted thereon is positioned below the grinding wheel.
