Problems solved by technology
In this process, there may be loss of design data in the step of model conversion, which will lead to problems such as inaccurate comparison of test results and reduced test efficiency.
In addition, in order to prevent piracy, inspection software such as SA needs to insert the configured dongle key into the computer when using it, which cannot be applied to specific occasions.

Embodiment Construction
[0020] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0021] The CATIA software that the present invention adopts is the CAD / CAM / CAE / PDM integration software of French Dassault (Dassault) company, comprises multiple modules such as part design, component assembly, simulation, digital processing, is the CAD widely used by enterprises such as aviation One of the software. The CAA is an extension of Dassault products and a user-customized development platform, which can carry out professional secondary development and realize seamless integration with the original CATIA system, which is conducive to user operation and integration. The laser tracker used in the present invention is a digital detection device for space three-dimensional coordinate measurement based on the principle of optical interference distance measurement and encoder angle measurement. The model is Leica AT 900, and its measuremen...

The invention discloses a component design and inspection integration method based on CATIA and a laser tracker. The CAA development platform is used to build a CATIA secondary development environment, and a "Measurement" module is added to the CATIA system. The module is connected by instruments and parameter settings , coordinate conversion, automatic measurement, position detection, straightness detection, type value deviation detection and other units. The CATIA software establishes communication with the laser tracker through the instrument connection unit, and based on this, realizes the parameter setting, coordinate system replacement, measurement data acquisition and detection result analysis of the laser tracker. Through the above steps, the conversion from the design model to the detection model can be avoided, and the integration of design and inspection is realized; in addition, the present invention also provides a custom development function, which is easier to operate, wider in use scenarios, and more efficient than general-purpose software .
Description
technical field [0001] The invention relates to the field of component manufacturing and assembly inspection, in particular to an integrated method of component design and inspection based on CATIA and a laser tracker. Background technique [0002] The production process of mechanical products is generally divided into four parts: design, parts manufacturing, component assembly and inspection. The inspection runs through the entire production process of the product and directly affects the production progress and product quality. Since the 1980s, computer-aided design and manufacturing (CAD / CAM) technology has developed rapidly, and the resulting digital design simulation technology, digital inspection technology, and digital information processing technology have been widely used in the production process of mechanical products. Applications. [0003] At present, digital inspection technology is mostly used in the external dimension inspection of parts and components with ...
