Device for detecting surface hardness of gun tube inner chamber based on robot and method

Abstract

The invention belongs to the technical fields of mechanical structures and equipment and methods for measuring the hardness of materials, and particularly relates to a device for detecting the surfacehardness of a gun tube inner chamber based on a robot and a method. The device comprises an inner chamber driver for driving movement along the axis of the tube, an eight-claw elastic automatic centering device for realizing automatic centering, a hardness measuring system for measuring the hardness of the inner surface of the gun tube and an optical monitoring system, the inner chamber driver isconnected with the eight-claw elastic automatic centering device, the eight-claw elastic automatic centering device is connected with the hardness measuring system, and the hardness measuring systemis connected with the optical monitoring system. The method is simple and feasible, the monitoring system can be used for checking the inner surface of the gun tube under the assistance of the robot,an expected trajectory line is designed according to the checked information, and then multi-point hardness testing is performed on the inner surface of the gun tube automatically along the designed trajectory under driving of an automatic travelling system.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures and equipment and methods for measuring hardness of materials, in particular to a robot-based detection device and method for the surface hardness of the inner bore of a gun barrel. Background technique [0002] Bore detection robot technology is a combination of sensing technology, control technology, information processing technology, machining technology, electronic technology, computer technology and other technologies. Therefore, the development of mobile robots must also be based on the rapid development of these technologies. The development trend of the gun bore inspection robot is mainly manifested in the following aspects: [0003] 1. Advanced sensing technology. The sensor is equivalent to the sensory organs of the mobile robot. Only advanced sensor technology can effectively collect environmental information, thereby improving the efficiency and accuracy of navigation. ...

AI Technical Summary

Problems solved by technology

Although the surface of the barrel will be chrome-plated after the production of the gun barrel is completed to increase the hardness and life of the inner surface, but during the use of the gun, surface defects such as ablation, corrosion, copper hanging, cracks, and rifling breaks will appear in the barrel barrel. The chrome plated will fall off after a long time of wear, which will affect the shooting accuracy and safety of use when it reaches a certain level. Therefore, regular inspections must be carried out on the artillery
