Comprehensive Inspection Method for Functional Gauges of Metal Cylinder Head Gaskets
This paper briefly describes the metal cylinder gasket comprehensive inspection method-functional gauge inspection method,focusing on the analysis of the characteristics of the gauge,and the design process.Cylinder gasket inspection report of each hole diameter and size with conventional inspection tools is easy to de-tect.But the position of the hole is difficult to detect.Now GB/T 8069-1998"functional gauge"is fully applica-ble to the use of the largest entity required to be measured elements and reference elements of the cylinder gasket detection.With a complete shape with the corresponding boundary of the element under test,belonging to the passage of the gauge"full-form through the gauge"to carry out the test,through that is qualified.The standard specifies the dimensional tolerance,form tolerance and allowable wear of the gauge,which essentially simulates the boundary to control the combined effect of the form tolerance of the centre element and the actual size of the corresponding contour element.
