Clamp assembly for testing adhesive force between tubular propellant and chemical fixing adhesive tape

Abstract

The invention relates to a clamp assembly and in particular relates to a clamp for testing adhesive force between a tubular propellant and a chemical fixing adhesive tape. The clamp for testing the adhesive force between the tubular propellant and the chemical fixing adhesive tape comprises a copper bar, a connection clamp, a tension rack, a fixture clamp and a shell, wherein a medical tube is arranged in the shell. According to the clamp for testing the adhesive force between the tubular propellant and the chemical fixing adhesive tape, the adhesive tape is used as an auxiliary material for increasing friction force and reducing friction sensitivity; the chemical tube and the copper bar are tightly wrapped with the adhesive tape, so that the copper bar and the chemical tube are integrated into a whole; a semicircular tube is arranged on the connection clamp; an inner thread is designed on the semicircular tube, so that the semicircular tube can be clamped; the spontaneous combustion and the spontaneous explosion generated by the friction in the drawing process are avoided; the safety problem in the testing process is solved; the working efficiency is improved.

Description

technical field [0001] The invention relates to a fixture assembly, in particular to a fixture assembly for testing the adhesive force of a tubular propellant and a solid drug glue. Background technique [0002] At present, the charge of the engine of the weapon system is mostly charged with a brush structure, that is, multiple tubular propellants are bonded to the engine through silicone rubber. During the storage process, to know whether the performance of the engine has changed, whether the launch is safe, and whether it has reached the originally set combat technical indicators, the charge performance of the engine must be analyzed and tested; in order to understand the various properties and adhesion of the propellant force changes. When testing the adhesion and other properties, it is necessary to pull out multiple tubular medicines from the engine. Due to the high friction sensitivity of the tubular medicines, the jigs during the pulling process are not suitable, or ...

AI Technical Summary

Problems solved by technology

When testing the adhesion and other properties, it is necessary to pull out multiple tubular medicines from the engine. Due to the high friction sensitivity of the tubular medicines, the jigs during the pulling process are not suitable, or they cannot be pulled out, or spontaneous combustion occurs due to friction Self-explosion; in addition, the gap between the roots of each brush-type charge is very small, the operation of the tooling fixture is very difficult, and the propellant has a high burning rate and high energy. personal injury accident
