Device and method for manually measuring normal thickness of large cavity deep radome

Abstract

The invention provides a device and a method for manually measuring normal thickness of a large cavity deep radome. The device comprises a radome measurement fixing device and a handheld radome normal thickness snap gauge, wherein the radome measurement fixing device comprises a measurement table, a radome shelf, a large-end fixing clip and a small-end fixing clip; and the handheld radome normal thickness snap gauge comprises a measurement main support, a reinforcing frame, a measurement micrometer head, a measurement micrometer head support, an inner measuring rod, an inner measuring rod support, a positioning micrometer head, a lengthened positioning rod and a positioning micrometer head support. The device has a composite measuring rack structure; the structure of the measurement snap gauge is designed optimally; and the measurement snap gauge can be light under the condition that the structural strength is guaranteed. The positioning measurement method is implemented by using the micrometer head, and a measured angle can be accurately and quickly positioned. The device has the advantages of high precision, low cost, convenience in operation and the like. Moreover, the device and the method have remarkable application value on measurement of the normal thickness of the radome.

Description

technical field [0001] The invention relates to a manual measuring device and a measuring method for the normal thickness of a large-cavity deep radome. Background technique [0002] The radome is a key part of the missile that integrates aerodynamics, structure and electrical performance. It is not only the head of the missile, it plays a role in protecting the guidance system from the harsh environmental conditions during aerodynamic flight, but also serves as the missile guidance control circuit. One of the links must ensure the undistorted transmission and reception of the microwave energy of the antenna. The wave transmission rate of the radome and the error of the line of sight will directly affect the missile's range, miss distance and stability. Therefore, the radome is a special product integrating aerodynamics, structure and electrical performance in the missile, which has a decisive influence on the performance of the guidance system. [0003] The normal thicknes...

Problems solved by technology

Small-sized thickness measuring devices can be adjusted by the operator based on experience and the minimum value can be read as the measured value. However, for thickness measuring devices with a depth of more than 600 mm, due to their large size, manual adjustment is extremely difficult, and there must be convenience, Accurate measurement angle positioning device
