Deburring tool and deburring method

Abstract

A deburring method includes rotating a case, a sleeve and a drive gear together with a spindle of a machining tool; transmitting rotating torque from the drive gear to a driven gear to rotate a tip tool together with a reciprocating shaft; receiving reactive torque to the tip tool in a reverse direction of a rotational direction of the case by a workpiece contact with the tip tool so that the reciprocating shaft rotates in a reverse direction of the rotational direction with respect to the sleeve; moving the reciprocating shaft to a basal end direction against an elastic force of a second spring with the driven gear sliding with respect to the drive gear; and cutting the workpiece by the tip tool.

What is claimed is: 
     
         1 . A deburring method, comprising:
 rotating a case, a sleeve and a drive gear together with a spindle of a machining tool;   transmitting rotating torque from the drive gear to a driven gear to rotate a tip tool together with a reciprocating shaft;   receiving reactive torque to the tip tool in a reverse direction of a rotational direction of the case by a workpiece contact with the tip tool so that the reciprocating shaft rotates in a reverse direction of the rotational direction with respect to the sleeve;   moving the reciprocating shaft to a basal end direction against an elastic force of a second spring with the driven gear sliding with respect to the drive gear; and   cutting the workpiece by the tip tool.   
     
     
         2 . The deburring method according to  claim 1 , further comprising:
 receiving thrust load to the tip tool from the workpiece; and   moving the sleeve toward a basal end direction against an elastic force of a first spring.   
     
     
         3 . The deburring method according to  claim 1 , further comprising:
 rotating the driven gear in the reverse direction of the rotational direction of the tip tool with respect to the drive gear while rubbing with the drive gear to move in the sleeve to the basal end direction.   
     
     
         4 . The deburring method according to  claim 2 , further comprising:
 rotating the driven gear in the reverse direction of the rotational direction of the tip tool with respect to the drive gear while rubbing with the drive gear to move in the sleeve to the basal end direction.
