Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] A measurement and inspection method for complex special-shaped castings based on laser tracking measurement of the present invention is as follows: figure 1 As shown, it is: use a measuring laser tracker or scanner to measure complex special-shaped castings to realize high-precision dimension scanning and measurement of the shape and inner cavity of the casting, so as to obtain the point cloud data of the shape and inner cavity of complex special-shaped castings. Then through the secondary development of software such as UG, the coordinate points are generated into a solid model, so as to realize the acquisition of the 3D model of the blank. Finally, based on the principle of position registration and inclusive analysis, the distribution law of the product machining allowance is obtained. Provide data support for subsequent CNC machining and manufactur...

Abstract

The invention discloses a complex special-shaped casting measurement checking method based on laser tracking measurement, wherein the method belongs to the field of machining manufacture and settles problems such as thin wall, cutting-through and insufficient thickness caused by a blank casting error after product machining. According to the method, a measurement laser tracker or a scanner is utilized for measuring a complex special-shaped casting, and high-precision dimension scanning and measurement to the profile and inner chamber of the casting are realized, thereby obtaining cloud data ofthe profile and the inner chamber point of the complex special-shaped casting. Then through software, a solid model is generated from coordinate points, thereby realizing three-dimensional model acquisition of a blank object. Finally position registering and inclusive analysis are used as basic comparison principles, thereby obtaining a product machining allowance distribution rule, and supplyingdata supporting for subsequent numerical control machining and qualified product manufacturing.

Description

technical field [0001] The invention belongs to the field of mechanical processing and manufacturing, and relates to the measurement and inspection of special-shaped cabins, in particular to the measurement and inspection of large and complex special-shaped castings. Background technique [0002] In the actual production of large and complex special-shaped casting cabins, the casting error of the blank often leads to problems such as thin wall, cut through, and loss of meat after product processing, and even leads to direct scrapping in severe cases. The key to solving this problem is to fully grasp the condition of the blank at the initial stage of machining, establish a three-dimensional model of the blank, and conduct a comprehensive inspection of the blank by comparing it with the design model. The current blank inspection mainly relies on thickness gauges and manual measurement by fitters, which has low efficiency and poor accuracy. Prominent problems such as long proc...
