Multi-linear constraint tensioning force measurement device on engine

Abstract

The invention discloses a multi-linear constraint tensioning force measurement device on an engine. The device comprises supporting rods, a beam, a steering seat, a graduation ruler, a first pulley, an L-shaped vertical rod frame, a second pulley, a third pulley, a steel rope and a pulling rod head, a groove is formed in a right-angle position of the vertical rod frame, the second pulley for penetrating the steel rope is mounted in the groove, a through hole for penetrating the steel rope is formed in the vertical rod frame corresponding to the pulley, the steering seat is welded at the tail end of the vertical rod frame, the third pulley for penetrating the steel rope is arranged in the groove in the upper portion of the vertical rod frame, the beam is welded on the vertical rod frame, the supporting rods are welded at two ends of the beam, a first pulley for penetrating the steel rope is arranged in a grooved in the upper portion of the steering seat, the graduation ruler for measuring stroke of the steel rope is arranged on the lower portion of the steering seat, the pulling rod head is fixedly arranged at the tail end of the steel rope, and the front end of the steel rope penetrates the graduation ruler and is connected with a tension meter. According to the device, measuring processes are more stable, the device cannot be deflected even if tensioning force is increased, limit of measurement space is solves by increasing a plurality of fixed pulleys, the direction of force is c hanged, and moving distance is shortened.

Description

technical field [0001] The invention relates to the field of aero-engine assembly, in particular to a multi-linear constraint tension force measuring device on the engine. Background technique [0002] Due to the complex structure of the nozzle feedback cable of a certain type of engine, the four steel cables cannot be fed synchronously during the measurement process, resulting in inaccurate measurement of the tension force measurement data, affecting the accuracy of the engine measurement system, unable to guarantee the engine assembly accuracy, and affecting the engine work ability. Contents of the invention [0003] The object of the present invention is to provide a multi-linear constraint tension force measurement device on the engine, which solves the difficult problem of measuring the tension force of the engine nozzle feedback steel cable, and realizes the tension force measurement with high precision requirements on complex accessories. [0004] The technical sch...
