Problems solved by technology

At present, on the processing equipment, after the parts are clamped, each processing surface is calibrated, and the processing standard is determined repeatedly. As the complexity of the processed parts increases, the workload of calibration also increases.
For the deformation of the combustion chamber casing beyond the margin range, it cannot be identified in advance

Abstract

The invention discloses a combustion chamber shell machining benchmark design method. The method comprises the following steps: firstly, placing a combustion chamber shell with an external hanging piece arranged on an outer surface and a laser three-dimensional scanner on a platform; 2, measuring the combustion chamber shell by using a laser three-dimensional scanner to generate a three-dimensional point cloud model; fitting the three-dimensional point cloud model with a preset three-dimensional design model of the combustion chamber shell; 3, taking the central vertical line of the three-dimensional design model as I-I reference, and taking the central horizontal line of the three-dimensional design model as II-II reference; and rotating the three-dimensional point cloud model around the central axis, and when the external hanging piece models of the three-dimensional design model are all located in the size range of the external hanging piece models of the three-dimensional point cloud model, determining a machining reference transmission value through a method of distance between a vertical plane and the central axis. The machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of combustion chamber casing processing, and in particular relates to a design method for processing a combustion chamber casing reference. Background technique [0002] In the process of processing, the combustion chamber shell adopts multiple processes, such as welding and heat treatment. When finishing the hanger, there are deformations and other situations, especially the material is high hardness, which cannot be enlarged without limit in the control of the finishing allowance. Therefore, in the finishing process, the machining reference position needs to ensure that all the machining surfaces are within the allowance range. At present, on the processing equipment, after the parts are clamped, each processing surface is calibrated, and the adjustment is repeated back and forth to determine the processing benchmark. As the complexity of the processed parts increases, the workload of calibration also inc...
