The role of auto inspection tools
2019-08-08
A gage is a special inspection device used to measure and evaluate the dimensional quality of a part.
In the parts production site, parts can be checked online by checking tools. For this, the parts must be precisely mounted on the inspection tool. Then, use a visual inspection or measuring table or caliper to inspect the surface and perimeter of the part. Inspection pin or visual inspection Visual inspection of the holes in different parts and the connection positions between parts and parts to ensure that the quality of parts is quickly judged during production.
In this case, you can tell by visual inspection or measurement:
The deviation between the size and shape area of the part profile and its relative position and the theoretical value of the instrument handled directly by CAD/CAM. For some extremely important functional dimensions on the part, it is also possible to use a measuring tool for numerical inspection.
It is usually not possible to obtain the exact coordinate values of the parts based on the coordinate system directly from the gage. Instead, the part is placed on the gage and measured by a coordinate measuring machine. When designing as a measuring table, the structure of modern measuring tools was also taken into account.
However, when the inspection function and measurement support function of the gage cannot be met at the same time, the online inspection function of the gage should be met first.
The measuring stand is an auxiliary stand used to measure parts using a coordinate measuring machine. All support surfaces (points) and positioning reference surfaces (points) must be milled according to the CAD data of the part. Measuring brackets of some special parts should also be used. There are some measuring functions.
The tester is a special testing equipment customized according to the requirements of the customer. The design of the gage must conform to the final 3D data and 2D drawings provided by the customer. The 3D data must have the correct car coordinate system. The design and manufacture of the fixture need to be processed and delivered through the customer's approval
