Abstract
A crimping apparatus is disclosed utilizing an angular motion actuator and a unique tooling bar arrangement to redirect the angular motion so that the crimping dies move along a straight line during the crimping process. Two identical tooling bars are utilized that interengage to form a sliding assembly so that the two crimping dies, formed in the tooling bars, move along the straight line. The tooling bars, which are operated by the actuator, have complementary recess and projected portions. The projected portion of each bar is nested within the recess of the other bar. Each tooling bar has an elongated opening and a pin that slidingly engages the elongated opening of the other tooling bar to limit the sliding motion to motion along a straight line.
Claims8
In an apparatus for operating a pair of mating tools in the performance of a manufacturing operation wherein the apparatus includes an actuator having first and second jaws pivotally attached thereto, said first and second jaws including first and second mutually opposed extended portions respectively, wherein, upon operation of said actuator, said jaws pivot thereby moving said extended portions along arcuate paths toward and away from each other, a parallel motion mechanism comprising:
- a pair of tooling bars coupled to respective ones of said extended portions, each of said tooling bars having a mating tool fixed thereto, said pair of tooling bars being coupled to each other for mutual reciprocating motion by a laterally extending pin of each said tooling bar which is in sliding engagement with an elongated opening of its respective other said tooling bar,
- wherein said movement of said extended portions along said arcuate paths toward and away from each other effects reciprocating movement of said mating tools toward and away from each other along a substantially straight line.
A crimping apparatus for crimping a first body onto a second body comprising:
- (a) an actuator having first and second jaws pivotally attached thereto, said first and second jaws including first and second mutually opposed extended portions respectively, wherein, upon operation of said actuator, said jaws pivot thereby moving said extended portions along arcuate paths toward and away from each other;
- and
- (b) a pair of crimp bars coupled to respective ones of said extended portions, each of said crimp bars having a mating crimp die, said pair of crimp bars being coupled to each other for mutual reciprocating motion by a laterally extending pin of each said crimp bar which is in sliding engagement with an elongated opening of its respective other said crimp bar,
- wherein said movement of said extended portions along said arcuate paths toward and away from each other effects reciprocating movement of said mating crimp dies toward and away from each other along a substantially straight line.
