Abstract
A crimp height adjusting mechanism in a machine for crimping terminals onto the ends of conductors of flexible flat cables. The adjusting mechanism is interposed between the movable crimping die and its drive mechanism and effects changes in crimp height by varying its length. The adjusting mechanism utilizes a sliding wedge block that causes a followed member to extend or recede a desired amount. An adjusting screw controls the sliding movement of the wedge so that very precise changes in crimp height can be achieved.
Claims10
In a machine for attaching terminals to conductors wherein said machine includes a frame, a mating crimping die and anvil set, movable means arranged for carrying said die through reciprocating motion toward and away from said anvil, said anvil being attached to said frame in alignment with said crimping die for mutual operational engagement
- a crimp height adjusting means coupled to said movable means for selectively altering the operational engagement spacing between said crimping die and said anvil comprising;
- (a) a plate having a first end and a second end, and an opening defining a bearing surface;
- (b) a wedge block having a first surface in sliding engagement with said bearing surface and a second surface opposite to and inclined to said first surface, said wedge block arranged to slide along said bearing surface in a direction toward said first end and in an opposite direction toward said second end, said second surface being inclined toward said bearing surface near said first end and inclined away from said bearing surface near said second end;
- (c) an adjusting screw substantially parallel with said bearing surface in threaded engagement with said wedge block and coupled to said plate so that upon rotation of said adjusting screw in one direction said wedge block is caused to slide along said bearing surface toward said first end of said plate and upon rotation in the other direction said wedge block is caused to slide toward said second end of said plate;
- and
- (d) a follower member coupled to said plate and having a longitudinal axis disposed substantially perpendicular to said bearing surface and arranged for limited reciprocating motion along said axis, said member including a follower surface in abutting engagement with said inclined second surface of said wedge block so that as said wedge block undergoes said sliding movement toward said first end said follower member moves outwardly along its said axis in a direction away from said bearing surface.
