Embodiment Construction

[0026] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] This embodiment proposes a casting cabin processing method based on precision detection technology, the main flow of the method is as follows figure 1 As shown, it specifically includes the following steps:

[0028] S1. Detect the inner and outer surface of the casting cabin by laser scanning method (such as figure 2 shown); compare the laser scanning detection results with the theoretical model of the casting cabin, and obtain the allowance data of the inner and outer molding surfaces of the casting cabin.

[0029] S2. Record the margin data at a specific position, and use the margin data at a specific position to align and mark the casting cabin datum: for cabin parts, the machining datum involves horizontal ...

Abstract

The invention belongs to the technical field of precision detection and processing, and particularly relates to a casting cabin section processing method based on precision detection technology. According to the method, high-precision detection methods such as laser detection and on-line detection are used before processing, the conditions such as the allowance and the defective number of a complex cast part are mastered, compared with a correction feature point allowance median fetching method adopted in a conventional alignment method, since allowance data of all positions are considered, the machining accuracy of the part can be guaranteed, and a relatively reliable machining standard can be obtained. In practical application, the method is used for marking and correction, the deviationis generally small, the subsequent processing can be met, and the quantity borrowing adjustment step is not used. The method of directly marking according to scanning data to establish reference processing is adopted, and analysis and judgment are facilitated; and compared with the method of repairing the standard by using a standard block, processing time is shortened, occupation of the equipment is reduced, and the method is a relatively fast processing method.

Description

technical field [0001] The invention belongs to the technical field of precision detection and processing, and in particular relates to a method for processing a casting cabin based on precision detection technology. Background technique [0002] In the casting process, the casting cabin is affected by heat treatment deformation factors, which are prone to defects such as insufficient wall thickness and insufficient shape allowance. Especially for non-circular special-shaped cabins, it is difficult to find dimensional defects during processing, it is difficult to establish correct processing benchmarks, and it is difficult to effectively control the accuracy of shape and wall thickness. The traditional method of large-area trial cutting will lead to low processing efficiency and borrow Quantitative judgment is difficult. Therefore, it is necessary to propose a casting cabin processing method based on precision detection technology to ensure the processing and detection accu...
