The Gage Is A Special Inspection Device For Measuring And Evaluating The Dimensional Quality Of Parts
- May 30, 2018 -

At the part production site, on-line inspection of parts is achieved through the inspection tool. To do this, the parts must be accurately mounted on the inspection tool. Then, visual inspections, or measurement tables, or calipers are used to inspect the part surface and the periphery. Inspection pins or visual inspections perform visual inspection of the holes of different parts and the connection position between the parts and the parts, so as to ensure the rapid judgment of the quality of the parts during production.


In this case, you can judge by visual inspection or measurement:


The deviation between the size and shape area of the part contour and its relative position and the gauge's theoretical value directly processed by CAD/CAM.


For some extremely important functional dimensions on the part, it is also possible to use a gage for numerical detection.


It is usually impossible to directly obtain the precise coordinate value of the part based on the body coordinate system by means of the inspection tool. Instead, the part is placed on the inspection tool and measured by a coordinate measuring machine.


The structure of modern gages is also considered during designing as a measuring stand.


However, when the inspection function of the inspection tool and the measurement support function cannot be satisfied at the same time, the online inspection function of the inspection tool should be satisfied first.


The measuring bracket is an auxiliary bracket used for measuring parts using a coordinate measuring machine. All its supporting surfaces (points) and positioning reference surfaces (points) must be milled according to the CAD data of the parts. Measurement brackets for some special parts should also be used. With some gage features.


The inspection tool is a special inspection equipment customized according to the demander's requirements. The design of the inspection tool must be in accordance with 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 inspection tool need to pass through the customer's Recognized for processing and delivery
