Automatic detection device for one interface of solid rocket engine

Abstract

An automatic detection device for one interface of a solid rocket engine includes a robot arm arranged on an omni-directional moving platform and an acoustic detection host, an acoustic probe used together with the acoustic detection host is arranged at the front end of the robot arm, the acoustic detection host is an electromagnetic acoustic detection host, and the acoustic probe is an electromagnetic acoustic probe. The automatic detection device for the one interface of the solid rocket engine uses an electromagnetic acoustic technology (EMAT) to carry out one-interface adhesiveness detection, so abuses brought by a coupling agent used in traditional detection methods are cover; and the detection field environment is identified through a 3D scanner, processing using an industrial control computer is carried out to generate an automatic tour route and an acoustic testing path, and the omni-directional moving platform cooperates with the robot arm to realize the automatic detection ofthe one interface, so the detection efficiency is high, and the detection result is objective and accurate.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic detection, in particular to a solid rocket motor-interface automatic detection device. Background technique [0002] The bonding interface between the solid rocket motor charge combustion chamber shell and the heat insulation layer is called an interface. The bonding performance of an interface directly affects whether the engine can work normally, and non-destructive testing of the bonding state of an interface is one of the important links in the production process of solid rocket motors. [0003] At present, the most commonly used detection method is the ultrasonic longitudinal wave multiple reflection method, which is a contact detection method. During the detection, it is necessary to apply coupling agent on the surface of the workpiece to be detected or immerse the workpiece in the coupling liquid, which has the following disadvantages: First, the coupling Second, the detection effect is...

Problems solved by technology

[0003] At present, the most commonly used detection method is the ultrasonic longitudinal wave multiple reflection method, which is a contact detection method. During the detection, it is necessary to apply coupling agent on the surface of the workpiece to be detected or immerse the workpiece in the coupling liquid, which has the following disadvantages: First, the coupling Second, the detection effect is greatly affected by whether the couplant is evenly applied. Third, the method usually needs to be manually completed by the operator, with low work efficiency and complicated operation steps. Fourth, it is difficult to guarantee detection due to human factors. Reliability and Consistency of Results
