Problems solved by technology

As a result, gross errors in manual measurement are often introduced, and it is difficult to ensure the pertinence of correction processing and the consistency of batch correction. The resulting transition correction and correction uncertainty will also affect the life of the wheel

Embodiment Construction

[0040] A detection data analysis and repair method of a train wheel rim tread of the present invention mainly includes several links of data collection, model building, model comparison, and result output, specifically including the following steps:

[0041] Step 1: Select a standard mold from the candidate mold library, and draw a standard mold data model according to multiple contour two-dimensional coordinate data of the standard mold.

[0042] Step 2: collecting a plurality of two-dimensional coordinate data of the contour line of the worn rim tread through the machine tool detection system, and drawing a data model of the wheel rim tread according to the plurality of two-dimensional coordinate data of the contour line. The step 2 includes:

[0043] Step 2.1: Collect multiple two-dimensional coordinate data of the contour line of the worn rim tread, and ensure that the ordinate of the starting position is greater than the ordinate of the starting position of the standard mo...

Abstract

The invention belongs to the technical field of non-falling wheel numerical control machine tools, and relates to a detection data analysis and repair method of a train wheel rim tread, including: drawing a standard mold data model and a worn rim tread data model; making the abscissas of the starting points of the two models the same; Translate the standard mold data model. When the abscissa is within the range from the peak point of the rim tread data model to the end point of the model, and the absolute value of the difference between the ordinates of the two models is less than the minimum removal value, stop moving; calculate the difference between the ordinates of the two models The cumulative sum of values; the processing program of the standard mold when the cumulative sum of the ordinate difference is the smallest is taken as the repair program; the point at which the abscissa of the starting position of the standard mold data model is increased by 70mm is the end point of the repair program; the wheel rim tread data model The point at which the abscissa of the starting position of the machine is increased by 70mm is the tool setting point; call the repair program, and input the coordinates of the tool setting point and the coordinates of the machining end point of the repair program into the non-falling wheel CNC machine tool system to realize intelligent automatic processing.

Description

technical field [0001] The invention belongs to the technical field of non-falling wheel numerical control machine tools, and relates to a detection data analysis and repair method for the wheel rim tread of a train wheel. Background technique [0002] In recent years, with the rapid development of my country's rail transit, the demand for wear correction of railway locomotive wheels has increasingly become the focus of research in the field of metal processing. The wheel of a railway locomotive is a rolling mechanism that supports the car body running on the track. It needs to have high wear resistance and smooth operation. During the running process of the wheels in contact with the rails, affected by conditions such as operating mileage, road conditions and vehicle speed, different wheel rim treads will have different wear conditions. The standard is contoured to ensure a greater shape match to the rail contact surface. In order to ensure that the shape can be corrected...
