<p>An assembly for releasably connecting a gripper finger 4 to a robotic arm includes a finger body 30 having a locking bar 37 extending therethrough and rotatable by means of a locking lever 38 in order to clamp mating gripper arms 8, 9 of gripper 6, the finger body 30 also having a cylindrical cavity or passageway 34 with first and second lips 36A, 36B, which passageway 34 receives a gripper bar 10 of the gripper 6. The locking bar 37 may comprise a pin 42 with a flanged first end (47 fig. 3), threaded at a second end into a sleeve (44 fig 3) with a flanged second end (48 fig 3). Rotation of locking lever 38 rotates pin 42 which thereby increases and decreases the engaged length of the locking bar 37 by means of the threaded engagement between pin 42 and sleeve (44 fig 3), causing its flanged ends (47, 48 fig 3) to engage and disengage with recesses (46, 50 fig 3) in gripper arms 8, 9, thereby clamping finger 4 to gripper 6. The threaded sleeve (44 fig 3) may be prevented from rotating by a roll pin (58 fig 3) in finger body 30 passing through a slot in the threaded sleeve (44 fig 3). Pin 42 may be retained on finger body 30 by means of a pilot screw (56 fig 3) in finger body 30 engaging a circumferential groove (54 fig 3) in the pin 42. The end of locking lever 38 may have a cylindrical cavity engagable with the end 12 of gripper bar 10 and retained by means of a threaded retaining pin (76 fig 7) in locking lever 38 engaging a groove (78 fig. 7) in the end 12 of gripper bar 10.</p> |
