Abstract

The invention provides an accurate measurement device for the tension of an aviation steel cable, which relates to the technical field of tension measurement equipment. The device for accurately measuring the tension of the aviation steel cable comprises a pulley (5), an upper pad (6), a lower pad (7), a force-measuring wire (8), a connecting plate (10), a wire to be measured (11) and The bottom plate (14), the upper cushion block (6) is provided with a side groove (15), and the lower cushion block (7) is provided with a plurality of T-shaped grooves (13), the centers of the two coincide, and a a through hole; one end of the connecting plate (10) is fixed on the bottom plate (14), and the other end is provided with a T-shaped piece (12); the number of pulleys (5) is four, which are arranged in a rectangular shape, at the center of the rectangle There is a red dot fixed on the base plate (14), one end of the force measuring wire (8) is connected with the sensor (2), and the other end is connected with the lead screw (9). The present invention solves the technical problem of insufficient precision of wire rope tension measurement.

Description

technical field [0001] The invention relates to the technical field of tension measurement equipment, in particular to an accurate measurement device for the tension of an aviation steel cable. Background technique [0002] Cable transmission is widely used in aircraft, among which the aircraft control system uses more cable transmission, generally aileron control, elevator control, rudder control, rudder surface lock control, rudder surface adjustment tab control, throttle control, etc. When the wire rope is driven, generally pay attention to the following four points: First, the wire rope must meet the pre-tightening force requirements after assembly. The accuracy of the operation is also easy to cause the pulley to wear; if the pre-tightening force is too large, the wire rope will bear an excessive load, and the friction between the wire rope and the pulley when rotating is also very large, which is easy to cause broken wires and laborious manipulation. Second, the tensi...
