摘要

这项工作致力于证明枪膛技术诊断方法的正当性,该方法基于使用激光三角测量工具确定其几何特征并在柱面坐标系中创建表面的详细图像。对现代枪炮内径技术诊断方法进行了分析,确定了其能力与日益增长的实际需要之间的矛盾。需要创造一种诊断方法和工具,以确保获得孔内表面的详细图像,并确定缺陷的类型及其表现程度。孔内表面的详细图像应以包含其内表面上点的空间坐标和孔半径的相应值的数据数组的形式呈现。结果表明,用激光三角测量法诊断孔是最方便的,它可以确定孔的几何特征,并在给定步长的柱坐标系中生成表面点的座标表。在每个部分中进行测量的点的数量取决于研究的目的和详细描述钻孔表面技术条件的要求。考虑了基于三角测量法确定目标控制表面距离的一般测量原理,以及传感器的结构及其与测量探头和定位模块集成的特点。提出了一种确定所需测量信息量和控制点数量的方法。定义了将测量结果分组到给定选项中的方法,以便在下一次分析中表示它们。

METHOD OF TECHNICAL DIAGNOSING OF THE BORES OF FIREARMS BASED ON THE DETERMINATION OF THEIR GEOMETRIC CHARACTERISTICS
The work is devoted to the justification of the method of technical diagnosing of the bores of firearms, which is based on determining their geometric characteristics using a laser triangulation measurement tool and creating a detailed image of the surface in a cylindrical coordinate system. An analysis of modern methods of technical diagnosing of the bores of firearms was carried out, and the contradiction between their capabilities and the growing needs of practice was determined. The need to create a diagnostic method and tool that would ensure obtaining a detailed image of the inner surface of the bore and identifying both the type of defect and the degree of its manifestation is substantiated. The detailed image of the inner surface of the bore should be presented in the form of a data array containing the spatial coordinates of the points on its inner surface and the corresponding values of the radius of the bore. It is shown that it is most expedient to diagnose the bore using the laser triangulation method, which makes it possible to determine their geometric characteristics and create tables of coordinates of surface points in a cylindrical coordinate system with a given step. The number of points at which measurements are made in each of the sections is chosen depending on the purpose of the research and the requirements for detailing the technical condition of the surface of the bore. The general principle of measurement based on the application of the triangulation method of determining distances to the controlled surface of the object, as well as the structure of the sensor and the features of its integration with the measuring probe and the positioning module, are considered. An approach to determining the required amount of measurement information and the number of control points is proposed. The method of grouping the measurement results into the given options for their presentation for the next analysis is defined.
