Many people know the mold, few people know the gage, what is the gage?
Gage is a special inspection equipment used to measure and evaluate the size and quality of parts. In the parts production site, through the inspection tool to achieve the online inspection of parts, to this end, the parts need to be accurately installed on the inspection tool, and then through visual inspection, or measuring scale, or calipers on the parts of the surface, the periphery of the inspection, you can also use the inspection pin or visual inspection of the different nature of the holes on the parts and the connection position between the parts. In order to ensure the rapid judgment of the quality status of parts during trial production and initial production.
In this case, the deviation between the size and shape area around the contour of the part and the relative position and the theoretical value of the gauge machined directly by CAD/CAM can be determined by eye inspection or measurement. For some extremely important functionality on the part. The size can also be numerically measured using the gage. Usually, the precise coordinate value of the part based on the coordinate system of the body can not be obtained directly with the help of the gauge, but the part is placed on the gauge and measured by the coordinate measuring machine. The construction of modern gauges is designed with its use as a measuring support in mind. However, when the online inspection function of the gage and the measuring support function cannot be met at the same time, the online inspection function of the gage should be met first.
In general: the inspection tool is a collection of special fixtures and inspection accessories directly used to test the size, shape and position characteristics of the product.
In general, automobile inspection tools are divided into measuring brackets, simple inspection tools and complete inspection tools according to the degree of difficulty. According to the manufacturer, it can be divided into self-made parts and external parts, according to the type of parts, stamping parts/fabric carpet/glass/plastic parts, etc.
