Actuator for testing torque wrenches has deflection mechanism for generating torque on head part of torque wrench in form of deflection lever acting on head part while support is static relative to lever

摘要

The actuator (10) has a support (12) for fixing a torque wrench (26) to be tested, a measurement transducer (16) arranged on the support coupled to the head part of the torque wrench, a handle holder (36) on the support for fixing the handle of the torque wrench and a deflection mechanism (52) for generating a torque on the head part in the form of a deflection lever acting on the head part while the support is static relative to the lever.
