End Effector

Abstract

An end effector may be configured to be modular in nature such that the weight of the end effector may be adjusted for specific applications. The end effector may further be configured to accept interchangeable dollies, wherein a dolly may be configured with a jacket on a contact end of the dolly, which contact end is configured to engage a distal end of a rivet during use.

1 . An end effector comprising:
 a. a housing neck having a neck bore along a length of said housing neck;   b. a housing section having a first end and a second end, wherein said housing section is engaged with said housing neck at said first end of said housing section;   c. a nose insert positioned within said housing neck, wherein said nose insert comprises:
 i. a nose insert bore formed along a length of said nose insert; 
 ii. a nose insert keyway formed adjacent an end of said nose insert, wherein a portion of said nose insert keyway intersects said nose insert bore; and, 
 iii. a keeper selectively engageable with said nose insert keyway; 
   d. a dolly engaged with said nose insert, wherein said dolly comprises:
 i. a first end positioned within said nose insert; 
 ii. a contact end extending from said housing neck; and, 
 iii. a shank connecting said first end with said contact end. 
   
     
     
         2 . The end effector according to  claim 1  further comprising a cap engaged with said second end of said housing section. 
     
     
         3 . The end effector according to  claim 1  wherein said dolly first end further comprises a keyway, wherein said keyway is alignable with said nose insert keyway such that said keeper is selectively engageable with said keyway. 
     
     
         4 . The end effector according to  claim 1  wherein said dolly further comprises a contact end groove formed on said contact end. 
     
     
         5 . The end effector according to  claim 1  wherein said end effector further comprises an insert positioned within said housing section. 
     
     
         6 . The end effector according to  claim 5  wherein said end effector further comprises a biasing member positioned between said nose insert and said intermediate insert. 
     
     
         7 . The end effector according to  claim 5  wherein said end effector further comprises a second insert positioned within said housing section. 
     
     
         8 . The end effector according to  claim 7  wherein said end effector further comprises a biasing member positioned between said insert and said second insert. 
     
     
         9 . The end effector according to  claim 1  wherein said end effector further comprises a sleeve positioned of an exterior portion of said housing section. 
     
     
         10 . The end effector according to  claim 1  wherein said dolly contact end further comprises a jacket engaged therewith, wherein said jacket surrounds a portion of a contact surface formed on said contact end of said dolly. 
     
     
         11 . The end effector according to  claim 10  wherein said jacket is further defined as comprising:
 a. at least three jacket sides connected with one another to form an enclosed periphery; 
 b. a work piece contact surface extending away from at least one said jacket side; and, 
 c. a jacket ridge formed on an interior surface of at least one said jacket side. 
 
     
     
         12 . The end effector according to  claim 11  wherein a distance between said work piece contact surface of said jacket and said contact surface is defined as a jacket height limit. 
     
     
         13 . The end effector according to  claim 12  wherein said contact end of said dolly further comprises a contact end groove, and wherein said contact end groove corresponds to said jacket ridge. 
     
     
         14 . The end effector according to  claim 13  wherein said jacket further comprises:
 a. a second work piece contact surface, wherein said work piece contact surface and said second work piece contact surface are oriented parallel with respect to one another; and, 
 b. a recessed portion, wherein said recessed portion is oriented perpendicularly with respect to said work piece contact surface and said second work piece contact surface. 
 
     
     
         15 . A jacket comprising:
 a. at least three jacket sides connected with one another to form an enclosed periphery;   b. a work piece contact surface extending away from at least one said jacket side; and,   c. a jacket ridge formed on an interior surface of at least one said jacket side.   
     
     
         16 . The jacket according to  claim 15  wherein said jacket further comprises a second work piece contact surface, wherein said work piece contact surface and said second work piece contact surface are parallel with respect to one another. 
     
     
         17 . The jacket according to  claim 16  wherein said jacket further comprises a first recessed portion and a second recessed portion, wherein said first recessed portion and said second recessed portion are oriented parallel with respect to one another and perpendicular with respect to said work piece contact surface and said second work piece contact surface. 
     
     
         18 . The jacket according to  claim 17  wherein said jacket further comprises a lip surrounding a portion of an interior periphery of said jacket. 
     
     
         19 . A rectangular jacket comprising:
 a. a first, second, third, and fourth jacket side, wherein said jacket sides are engaged with one another and configured to form a rectangle-shaped periphery;   b. a work piece contact surface extending away from said first jacket side;   c. a jacket ridge formed on an interior surface of said first jacket side.   
     
     
         20 . The rectangular jacket according to  claim 19  further comprising a second work piece contact surface extending away from said third jacket side.
