Adjustment mechanism for adjusting jaws of shear

摘要

A hydraulic shear including a first jaw, a second jaw, a pivot pin, and an adjustment mechanism is provided. The first jaw includes a first and second sidewall defining a first and second opening therethrough. The second jaw is disposed between the first and second sidewalls and includes a third opening. The pivot pin extends through the first, second, and third openings to pivotally connect the first and second jaws. The adjustment mechanism is coupled to the first jaw, the second jaw, and the pivot pin. The adjustment mechanism slidably adjusts a position of the second jaw on the pivot pin with respect to first and second sidewalls of the first jaw.

主权项

1. A hydraulic shear comprising:
a first jaw including a first sidewall with a first opening therethrough and a second sidewall with a second opening therethrough; a second jaw disposed between the first and second sidewalls, the second jaw including a third opening; a pivot pin including a head portion and a rod portion, the pivot pin extending through the first, second, and third openings to pivotally connect the first and second jaws; and an adjustment mechanism coupled to the first jaw, the second jaw, and the pivot pin, the adjustment mechanism configured to slidably adjust a position of the second jaw on the pivot pin with respect to the first and second sidewalls, the adjustment mechanism including: the head portion of the pivot pin being in the first opening, and the rod portion of the pivot pin extending from the head portion and including a threaded end adjacent the second opening; a nut adjustably engaged with the threaded end the nut being releasably secured to the second sidewall and rotatable to move the head portion relative to the second jaw to slidably adjust the position of the second jaw on the pivot pin with respect to the first and second sidewalls; and at least one shim and at least one low-friction plate disposed on the pivot pin, and located between the first and second jaws.
