Flexible Electromechanical Punching Device

Abstract

A flexible electromechanical punch device mounted on, or controlled by, a robot arm or similar is disclosed. In one example embodiment, it is further intended to hold a series of punch tools and cushion, or a multiple tool, connected to a multiple punch which, in itself, may be connected to a base body with attached linear gear system and electromechanical drive unit over a tool change system, in such a syncronized way that a spring retract system will be eliminated and that full control of the punch tool position in all directions will be met and that full feedback of motor current and position of the tool during penetration makes it possible to determine that a good punch has been performed relative the supposed material to be punched.

1 . Flexible electromechanical punching device intended to be a part of a robot arm or similar for flexible punching of holes with one or several shapes in metal, plastic or any other material, comprising: 
 a base body where a linear gear system, an electromechanical drive unit and a tool change system is attached and automatically or manually is connected to a multiple punch which contain a multiple tool with individual punch tool including corresponding cushion.    
   
   
       2 . Flexible electromechanical punching device according to  claim 1;  the electromechanical drive unit has a control system syncronized with robot axis controller in such a way that a syncronized movement with all involved axis are performed during retract of the punch tool eliminating the need of an additional spring back retract system.  
   
   
       3 . Flexible electromechanical punching device according to  claim 1;  wherein the electromechanical drive unit control system momentarily supervise actual current value in such a way that the force will be monitored.  
   
   
       4 . Flexible electromechanical punching device according to  claim 1;  wherein the electromechanical drive unit control system momentarily supervise resolver/encoder value in such a way that the position of the tool will be monitored.  
   
   
       5 . Flexible electromechanical punching device according to  claim 1;  wherein a linear gear system is connected to a punch tool, direct or indirect through a tool change device.  
   
   
       6 . Flexible electromechanical punching device according to  claim 1;  wherein a base body is connected to a multiple punch, direct or indirect through a tool change device.  
   
   
       7 . Flexible electromechanical punching device according to  claim 1;  wherein the multiple punch may be equipped with a multiple tool arranged in such a way that an indexing, linear or rotational, is performed to place the correct tool into the seat of the multiple tool.  
   
   
       8 . Flexible electromechanical punching device according to  claim 1;  wherein the waste material in the punching operation will be kept in the cushion until a desired time chosen.
