Embodiment Construction

[0035] The method for measuring the volume of the cartridge chamber of the present invention is characterized in that it comprises the following steps:

[0036] 1. The measuring fixture is made of elastic film material;

[0037] 2. Put the measurement fixture into the body cavity of the projectile chamber to be measured, fix the projectile to be measured, and put the measurement fixture and the liquid into the pipeline, the liquid into the pipeline and the liquid container, and the liquid container to the pressure cylinder. connected;

[0038] 3. Start the pressure cylinder, with the help of the hydraulic thrust of the pressure cylinder, inject the liquid in the liquid container into the fixture through the liquid adding pipeline, so that the elastic film material of the measuring fixture is in close contact with the inner cavity of the body until the measuring fixture is full of liquid under the action of the liquid. The body cavity of the body drug chamber; measure the forw...

Abstract

The invention discloses a method and a device for measuring a bomb chamber volume. The method comprises the following steps of: manufacturing a measuring fixture by using an elastic thin-film material; putting the measuring fixture into a bomb inner cavity of the bomb chamber to be measured, fixing the bomb to be measured, and correspondingly connecting the measuring fixture with a liquid addition pipeline, connecting the liquid addition pipeline with a liquid accommodating container and connecting the liquid accommodating container with a pressure cylinder; starting the pressure cylinder, injecting liquid into the fixture by means of thrust of the pressure cylinder so as to tightly contact the elastic thin-film material of the measuring fixture with the bomb inner cavity, and calculatingthe volume of liquid which is added into the measuring fixture; and adding the volume of the measuring fixture and the volume of the liquid added into the measuring fixture to obtain the bomb chambervolume. The measuring method and the measuring device have high measurement accuracy; the degree of automation is high, and higher measurement accuracy is achieved; the measuring efficiency is high; the measuring equipment has simple structure and low cost; and the technology breaks through the tradition.

Description

Technical field: [0001] The invention relates to a method and a device for measuring the volume of an inner cavity, in particular to a method and a device for measuring the volume of an ammunition chamber of an artillery shell rapidly and accurately. [0002] Background technique: [0003] In the processing technology of artillery shells, the amount of charge in the shell is a very critical parameter, so it is an important process to accurately detect the volume of the shell chamber, and it is also a difficult problem in the current domestic military industry. For a long time, in the production process of shells, military enterprises have used the "water weighing method" (that is, to divide the mass difference before and after the water injected into the shells into the shells by the density of water) to measure the volume of the shells. The method not only takes a lot of time and effort, but also has large errors in the detection results, which cannot adapt to the requir...
