Device and method for measuring radial clearance after missile empennage assembling

Abstract

The invention provides a device and a method for measuring a radial clearance after missile empennage assembling. The measuring device is composed of a fixing assembly and a measuring assembly, and the measuring assembly is composed of an adjusting device and a measuring unit; the fixing assembly is used for supporting a projectile body; the adjusting device is mainly composed of a lever, a leversupport, a lever contact, a lever load block, a lever loading block, a handle, a handle support, a cam, a test load block and a pin shaft. The lever support and the handle support are fixed on a tabletop bottom plate, and the lever is provided with a sliding chute, is connected with the lever support through a screw and is fastened by a butterfly nut; the lever contact is fixed at the front end of the lever; the lever load block is fixed at the tail end of the lever; the handle and the cam are fixed to the handle support through a pin shaft, and the cam is arranged below the lever and can bedriven by the handle to rotate and jack up the lever. The measuring unit is used for measuring the empennage clearance. The measuring device is simple and convenient to measure.

Description

technical field [0001] The invention belongs to the technical field of measuring devices, and in particular relates to a measuring device and a measuring method for radial clearance after assembly of an upper empennage. [0002] technical background [0003] The rotating tail is one of the common tail structures in the canard layout of missiles. The flexibility of the tail rotation directly affects the flight quality of the missile. The rotation of the tail is realized by two bearings in the tail. The sum of the fit clearance between the empennage and the bearing, the bearing and the engine, and the clearance of the bearing itself is called the empennage clearance, which determines the rotational flexibility of the empennage when it is working. [0004] If the tail clearance is too small, the bearing will be stuck or unable to rotate. If the tail clearance is too large, the vibration environment of the tail will deteriorate. In severe cases, the bearing and the tail will be d...

AI Technical Summary

Problems solved by technology

[0004] If the tail clearance is too small, the bearing will be stuck or unable to rotate. If the tail clearance is too large, the vibration environment of the tail will deteriorate. In severe cases, the bearing and the tail will be damaged, which will affect the service life of the tail. The clearance directly determines the flexibility of the tail rotation, which in turn affects the flight quality of the missile. Therefore, it is very important to measure the clearance of the tail after the tail is assembled.
