Airplane hanging point position detection device

Abstract

The invention discloses an airplane hanging point position detection device, and belongs to the field of test and measurement designs. The detection device comprises a cross shaft component, long shafts, a sliding bush component and a short shaft component. The transverse spacing of hanging points is measured by inserting one end of each of two long shafts into a left hanging point and a right hanging point respectively, inserting the other end of each of the two long shafts into transverse adjusting shafts on two sides of a transverse adjusting shaft component respectively, and reading the spacing between the left hanging point and the right hanging point by using scales on the transverse adjusting shaft component, and the depths of the long shafts inserted into the hanging points are adjusted to achieve an aim of avoiding obstacles between the hanging points. The coaxiality of the hanging points is measured by inserting the long shafts into front hanging points, inserting short shafts into back hanging points, and connecting the sliding bush component with two shafts. During measurement, the top ends of the short shafts are laminated with a sliding bush, the position of a slotted sliding block of the sliding bush component on the sliding bush and the angles between the sliding bush component and the long shafts are adjusted to ensure that a semicircular surface of the lower part of the slotted sliding block is laminated with a short shaft, and coaxiality deviation data of front and back hanging points is read by using scales. The detection device disclosed by the invention has relatively low requirements on objective conditions including an operating space, a measurement environment and the like, is simple to operate, and can obtain measurement data in real time.

Description

technical field [0001] The invention belongs to the field of test measurement design, and in particular relates to a position detection device for an aircraft suspension point. Background technique [0002] The thrust reverser is connected to the aircraft through the hanging point of the aircraft pylon. Therefore, it is necessary to measure and verify the accuracy of the hanging point of the pylon. Aircraft hanging point position detection usually refers to the coaxiality measurement of the same side of the aircraft hanging point, and the distance measurement of different measurement hanging points. The traditional detection of the aircraft hanging point position is usually completed by laser tracker electronic equipment. The tracker is expensive and complicated to operate. The instrument has high requirements on the test environment and data processing is time-consuming. Due to the particularity of the operating environment of the aircraft pylon, a convenient, easy-to-oper...
