Arch grinder by rotary mechanism

The utility model relates to an arch grinder by rotary mechanism. The problem that needs to solve is the existing background art: the cambered surface grinding can not be finished on the rotating equipment. A special grinding equipment needs to be added if the grinding machining needs to be finished, that increases the cost and wastes the function resources of the equipment. The key points of adopting art project to solve the art problem is: a front and a back-splints are fixed on the main equipment through fastening bolt, the front-splint connects the tightening-board through the torsion spring, the tightening-board connects the driven gear, the rotation axis on the main equipment connects the driven gear, the driven gear connects the driven gear through an abrasive belt, a pad is arranged on the working-table of the main equipment, a supporting-plate is arranged on the pad, a cambered-plate is arranged in the front of the supporting-plate, a falling-plate is provided between the supporting-plate and cambered-plate. The utility model can used to varied rotation equipments and realize the grinding processing of cambered surface that uses the rotation equipment resources and saves the cost of processing equipment.
