US 8,806,961 B1 · Portable pneumatic impact wrench testing machine

Abstract

The portable pneumatic impact wrench testing machine is a portable torque tester that tests the torque output of a pneumatic impact wrench. The machine includes a first member that is hingedly attached to a second member via a hinge member. A hydraulic jack is positioned between the first member and the second member, and includes a gauge that translates compression or pressure imposed on the hydraulic jack into torque that an impact wrench is inputting. A bolt member is positioned between the hinge member and hydraulic jack, and the bolt member passes across the first member and the second member. A nut extends on an outer surface of the second member, and is threadably engaged to the bolt member. The impact wrench rotates said nut thereby squeezing the first member towards the second member in order to compress the hydraulic jack positioned there between.

Dependent claims

A portable pneumatic impact wrench testing machine comprising:

a first member and a second member that rotate with respect to one another via a hinged member;
wherein a hydraulic jack is sandwiched between the first member and the second member at a distal end opposite of the hinged member;
wherein a bolt member passes across the first member and the second member, and which includes a nut that is threaded onto the bolt member at an outer surface of the second member;
wherein the nut is configured for use with a pneumatic impact wrench, which when tightens said nut shall squeeze the first member towards the second member in order to compress the hydraulic jack positioned there between.
