TRIGGER MECHANISM PERFORMANCE TEST STAND

摘要

FIELD: firearms engineering.; SUBSTANCE: test stand comprises a base, firearm fixation elements, a load-applying unit, a trigger movement and firing load control unit and a friction roll. The friction roll interacts with the trigger. Firearm fixation elements are in the form of supporting arm with three adjustable thrust plates. These thrust plates ensure the three-sided fixation of the firearm. The firearm is fixed from the fourth side by an adjustable reed spring. The supporting arm is installed on a movable carriage which functions as a load-applying unit. This movable carriage is connected with a screw pair and moves along a longitudinal slide. The firing load control unit is a force sensor connected with the friction roll by a fixed tie beam.; EFFECT: more precise trigger mechanism performance measurement.;5 dwg
