Mixed multiaxial pivoting head

Abstract

The invention relates to a multiaxial pivoting head intended to be mounted at the end of moving arm ( 22 ) of a machine-tool, said pivoting head comprising, on the one hand, a yoke ( 30 ) including a support shaft ( 32 ), said yoke being able to be mounted rotatably on said arm ( 22 ), while said support shaft ( 32 ) extends substantially perpendicular to said arm ( 22 ), and on the other hand, at least two working members ( 38, 40 ) installed on said support shaft ( 32 ) in positions angularly offset relative to one another, said support shaft ( 32 ) being rotatable to be able to alternately bring each of said at least two working members ( 38, 40 ) between a position retracted inside said yoke ( 30 ) and a working position protruding from said yoke. One of said at least two working members ( 40 ) is a waterjet cutting device.

1 . A multiaxial pivoting head intended to be mounted at the end of moving arm of a machine-tool, said pivoting head comprising, on the one hand, a yoke including a support shaft, said yoke being able to be mounted rotatably on said arm, while said support shaft extends substantially perpendicular to said arm, and on the other hand, at least two working members installed on said support shaft in positions angularly offset relative to one another, said support shaft being rotatable to be able to alternately bring each of said at least two working members between a position retracted inside said yoke and a working position protruding from said yoke;
 wherein one of said at least two working members is a waterjet cutting device.   
     
     
         2 . The multiaxial pivoting head according to  claim 1 , wherein said waterjet cutting device includes an injection nozzle and a recovery receptacle mounted across from said injection nozzle. 
     
     
         3 . The multiaxial pivoting head according to  claim 2 , wherein said injection nozzle extends in an inclined direction relative to the tangent to said support shaft. 
     
     
         4 . The multiaxial pivoting head according to  claim 2 , wherein said waterjet cutting device comprises a discharge duct connected to said recovery receptacle. 
     
     
         5 . The multiaxial pivoting head according to  claim 2 , wherein said waterjet cutting device advantageously comprises an abrasive particle intake duct connected to said injection nozzle. 
     
     
         6 . The multiaxial pivoting head according to  claim 2 , wherein said waterjet cutting device comprises a V-shaped maintaining member having two branches to keep said recovery receptacle opposite said injection nozzle. 
     
     
         7 . The multiaxial pivoting head according to  claim 6 , wherein said V-shaped maintaining member is mounted rotatably mobile around an axis substantially perpendicular to said support shaft. 
     
     
         8 . The multiaxial pivoting head according to  claim 6 , wherein said V-shaped maintaining member further comprises a fastening platen arranged on one of said two branches to be able to fasten said V-shaped maintaining member to said support shaft. 
     
     
         9 . The multiaxial pivoting head according to  claim 8 , wherein the other of said two branches receives said recovery receptacle. 
     
     
         10 . The multiaxial pivoting head according to  claim 4 , wherein said waterjet cutting device comprises a V-shaped maintaining member having two branches to keep said recovery receptacle opposite said injection nozzle, and wherein said V-shaped maintaining member includes a passage pathway emerging in said receiving receptacle and in said fastening platen to form a portion of said discharge duct. 
     
     
         11 . The multiaxial pivoting head according to  claim 1 , further comprising a water pressurizing device coupled to said waterjet cutting device, and wherein said water pressurizing device is able to be housed inside said moving arm.
