Embodiment Construction

[0017] The present invention will be further described below in conjunction with some specific examples.

[0018] Take the volute product as an example: scan the product: scan the whole product through the scanner, and obtain the 3D data of the whole product;

[0019] Cutting products: Carry out wire cutting according to the cutting diagram given by the customer. During the cutting process, the following points must be paid attention to: cutting molybdenum wire ≤ 0.2mm; the position of the tip of the tongue must not be cut; ensure that the thickness of a single part is as much as 20mm above; the cutting distance should be short, the shorter the distance, the smaller the deformation;

[0020] Fragmented scanning: clean the divided product, then scan the divided body, and obtain the three-dimensional data of each divided body;

[0021] Data import and alignment: 1. Open the GEMO software, first import the overall 3D data and the 3D data of each split into the GEMO software, cha...

Abstract

The invention discloses a method for detecting the separation condition of a product, wherein the method comprises the following steps: scanning the product: scanning the whole product through a scanner, and obtaining the three-dimensional data of the whole product; cutting the product: carrying out linear cutting on the product according to a sectioning schematic diagram given by a client; carrying out split body scanning: cleaning the split body of the segmented product, then scanning the split body, and obtaining three-dimensional data of each split body; importing and aligning data: importing the three-dimensional data of the whole body and the three-dimensional data of each split body into Geomagic software, and aligning the data of the whole body and the three-dimensional data of each split body; separating the product: separating an inner flow channel and an outer contour of the product in the Geomagic software to obtain three-dimensional data after separation; carrying out three-dimensional comparison: comparing the three-dimensional data after separation with theoretical three-dimensional data; and issuing a scanning report: annotating the result, and issuing the scanning report. According to the method, the deviation of an actual product relative to a theoretical design can be evaluated from macroscopic and microscopic angles, so that the performance of the product is optimized.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a method for detecting product separation. Background technique [0002] Before the inspection of the turbine casing flow channel, the image measurement section H value, R value, Ra value and the theoretical size are compared to determine whether the flow channel size meets the design requirements. This inspection method can only be judged from the macroscopic size, and the subtle contour difference cannot be judged. And it cannot quantitatively guide design engineers to optimize the flow channel structure to improve performance. [0003] Patent CN201310718525.4 discloses a method for detecting the inner cavity of a sand mold, which belongs to the field of foundry products. The steps are: (A) heating the cavity detection agent in solid state to 45°C to make it into a liquid state, and at the same time heating the sand mold, the temperature of the sand mold is 340-50°C; (B) the ...
