Bogie axle automatic detection system

Abstract

A bogie axle automatic detection system disclosed by the present invention comprises a measurement assembly fixedly installed on a base, the measurement assembly comprises an axle identification part and a measurement part, and the base is slidably connected with an axle positioning frame used for fixing and limiting an axle. Axle driving mechanisms are arranged at the two sides of the end, close to the measuring component, of the base respectively, the axle driving mechanisms clamp an axle and enable the axle to rotate so that the axle identification component can identify and detect the number of the axle, an axle rotating mechanism is arranged on the axle positioning frame, and the axle rotating mechanism drives the axle to rotate. The axle positioning frame, the measuring assembly, the axle driving mechanism and the axle rotating mechanism are fixedly mounted on the base to form a measuring component for detecting the diameter and the curvature of the axle and detecting whether a positioning ring, a bearing or a gear is dismounted from the surface of the axle. The base is fixedly provided with a control mechanism for controlling the axle positioning frame, the measuring assembly, the axle driving mechanism and the axle rotating mechanism. The method adapts to the technical field of mechanical detection.

Description

technical field [0001] The invention belongs to the technical field of mechanical detection, and in particular relates to an automatic detection system of a bogie axle. Background technique [0002] The existing detection of the axle on the bogie includes diameter measurement, curvature measurement, scratch and damage inspection of the axle. When measuring the diameter of the axle, the axle needs to be placed on a special measurement bracket and measured with a dry ruler. Diameter, measure the shaft diameter according to the specified points of the steering axle and record the data. After the first group is measured, rotate the axle 90° and measure again. The diameter range of the axle is 130-225mm; The axle is fixed on the auxiliary rotating support to rotate the axle, and the circular runout of the axle surface is measured with a dial indicator; scratches and damage inspections are carried out on the axle, and manual inspection is performed with eyes and hands to see if th...

[0002] Existing detection of the axle on the bogie includes diameter measurement, curvature measurement, scratch and damage inspection of the axle. When measuring the diameter of the axle, It is necessary to place the axle on the special measurement bracket, measure the diameter with a dry ruler, measure the axle diameter in turn according to the points specified by the steering axle and record the data, after the first group is measured, rotate the axle 90° and measure again, the axle diameter The range is 130-225mm; when measuring the bending degree of the axle, it is necessary to fix the axle on the auxiliary rotating support to rotate the axle, and use a dial indicator to measure the circular runout of the axle surface; to inspect the axle for scratches and damage, artificial eyes Go to see and touch with your hands, initially want to see if there are obvious scars, and then use non-destructive testing to check the existing bogie to axle measurement of the diameter, curvature, and scratches of each installation position on the bogie axle And damage inspection, the existing measurement methods have the following centralized problems: first, the amount of data is large, there are many types of bogie axles, and each axle needs to measure a lot of point data, and it needs to be rotated in the middle, so the measurement is inconvenient; second 1. Accuracy, the amount of data is large and cumbersome, and manual operation is prone to errors; 3. Electronics, the measurement data are all manually recorded, which is not easy to browse and save
