Abstract
An in-line portable, handheld hydraulic scissor-type action crimping tool having a handle assembly and a working head assembly is provided. The handle assembly has a tool frame portion and a neck portion. The working head assembly has a pair of jaw members joined so that they are movable relative to each other and held in place by a locking pin. One jaw member has a nest secured to or directly formed into the jaw member. The other jaw member has an indentor secured to or directly formed into the jaw member.
Claims23
A working head assembly for a hydraulic crimping tool operating on a work object, the working head assembly comprising:
- a first jaw member having a proximal end portion and a distal end portion, the distal end portion including a nest configured to receive the work object and a stop, the first jaw member having at least one bore;
- a second jaw member having a proximal end portion and a distal end portion, the distal end portion including an indentor having an impacting surface protruding toward the nest and a bumper, the impacting surface being configured to contact the work object, the second jaw member having at least one bore which when aligned with the at least one bore of the first jaw member defines a pivot point, wherein when the distal end portion of the first jaw member and the distal end portion of the second jaw member move toward each other the bumper contacts the stop so that the indentor is inhibited from contacting an interior surface of the nest;
- a spring having a first end attached to the proximal end portion of the first jaw member and a second end attached to the proximal end portion of the second jaw member that normally biases the proximal end portion of the first jaw member toward the proximal end of the second jaw member;
- and
- a locking pin that extends through the at least one bore in the first jaw member and the at least one bore in the second jaw member when the bores are aligned to releasably couple the first jaw member to the second jaw member.
