Head for a robot ar intended to perform a deflashing or rouging operation

Abstract

The invention relates to a head for a robot arm, which is intended to perform a deflashing or carding operation. The inventive head comprises: a plate which is fixed to the arm of the robot; a shaft which is mounted to the plate in parallel therewith; a support for a deflashing or carding tool, which is pivot mounted around the shaft in an extension of the area where the plate is fixed to the arm of the robot; a jack which is mounted coaxially to the shaft which is connected to one end of a connecting rod, the other end thereof being connected to the above-mentioned tool support in order to adjust the orientation thereof; and means for driving the tool which is used to equip a robot arm and which is intended to perform a deflashing or carding operation.

1 . A head for equipping a robot arm, intended to perform a deflashing or roughing operation, and which comprises: 
 a fixing plate for fixing to the robot arm,    a shaft mounted on the plate parallel thereto,    a support for a deflashing or roughing tool mounted to pivot about the shaft and in the continuation of the region of fixing of the plate to the robot arm,    an actuator mounted coaxial with the shaft, connected to one end of a link rod the other end of which is connected to the tool support so as to adjust the orientation of this tool, and    tool drive means.    
   
   
       2 . The head as claimed in  claim 1 , wherein the actuator for driving the link rod is a rotary actuator.  
   
   
       3 . The head as claimed in claims  1 , wherein the link rod for adjusting the orientation of the tool acts on the tool support via a compensation actuator.  
   
   
       4 . The head as claimed in  claim 1 , wherein, in the case of a deflashing head, this head comprises an electric motor positioned along the axis of the shaft, at the opposite end to the actuator for adjusting the position of the tool support, the output shaft of the motor being equipped with an eccentric acting on a link rod for driving the moving blade of a pair of deflashing shears.  
   
   
       5 . The head as claimed in  claim 1 , wherein, in the case of a roughing head, this head comprises an electric motor secured to the support of axis perpendicular to the shaft, on which the support is mounted to pivot, and onto the output shaft of which a roughing wheel is keyed.  
   
   
       6 . The head as claimed in  claim 2 , wherein the link rod for adjusting the orientation of the tool acts on the tool support via a compensation actuator.  
   
   
       7 . The head as claimed in  claim 2 , wherein, in the case of a deflashing head, this head comprises an electric motor positioned along the axis of the shaft, at the opposite end to the actuator for adjusting the position of the tool support, the output shaft of the motor being equipped with an eccentric acting on a link rod for driving the moving blade of a pair of deflashing shears.  
   
   
       8 . The head as claimed in  claim 3 , wherein, in the case of a deflashing head, this head comprises an electric motor positioned along the axis of the shaft, at the opposite end to the actuator for adjusting the position of the tool support, the output shaft of the motor being equipped with an eccentric acting on a link rod for driving the moving blade of a pair of deflashing shears.  
   
   
       9 . The head as claimed in  claim 2 , wherein, in the case of a roughing head, this head comprises an electric motor secured to the support of axis perpendicular to the shaft, on which the support is mounted to pivot, and onto the output shaft of which a roughing wheel is keyed.  
   
   
       10 . The head as claimed in  claim 3 , wherein, in the case of a roughing head, this head comprises an electric motor secured to the support of axis perpendicular to the shaft, on which the support is mounted to pivot, and onto the output shaft of which a roughing wheel is keyed.
