Tool locking system

Abstract

A locking system for securing tools on an arbor. The locking system has a collar attached to the arbor, with the collar spaced from the tooling. A nut is placed over the collar and positioned next to the tools. The nut is then rotated to secure the nut between the collar and the tools.

1 . A locking system for securing tools on a metal forming machine comprising:
 said arbor including a collar, said collar spaced from said tooling;   a nut, said nut slidable over said collar and positioned adjacent said tooling in a first position, said nut being shiftable relative to said collar from said first position into a second position overlying said tools and secured between said collar and the tools.   
     
     
         2 . A locking system as claimed in  claim 1 , wherein said nut is rotatable relative to said collar between said first position and said second position. 
     
     
         3 . A locking system as claimed in  claim 2 , wherein said collar has spaced flanges on said collar, said nut having spaced internal flanges, said internal flanges passing between said collar flanges as said nut is slid over collar into its said first position said internal flanges on said nut between said tooling and said collar flanges hen said nut is in its said second position located on said collar. 
     
     
         4 . A locking system as claimed in  claim 1 , wherein said nut has a groove, said groove receiving said pressure ring to form a chamber within said nut, said chamber receiving a pressure forming source to extend said pressure ring apart for said tooling on said arbor when said nut is in its said second position.
