Background
The piston is a core part of the diesel engine, and the processing size quality of the piston determines the combustion performance of the diesel engine, so the detection of the piston is important quality control work in the production process of the diesel engine; along with the development of three-coordinate machine technology, utilize three-coordinate to detect the piston, measure the detection means of examining the utensil relatively the tradition, can effectively improve and detect precision and efficiency.
In the machining process of the piston, the sizes of the ring groove, the pin hole and the like are machined by taking the spigot ring surface as a reference for positioning, the spigot ring surface is detected by three coordinates according to the principle that the detection reference is consistent with the technological machining reference, the spigot ring surface is defined as a reference surface, and then the measurement results of all parameters are evaluated by the reference. Because the narrowest part of the width of the spigot ring surface of the piston is less than 3mm, the three-coordinate 3mm measuring head can only measure the edge in order to avoid wall collision during detection, and because the force measurement of the three-coordinate measuring head is very small, the spigot ring surface is sprayed with graphite, and the edge has tiny deformation such as burrs, the three-coordinate direct measurement of the spigot reference surface is inaccurate, and the accurate evaluation of each subsequent measurement parameter is influenced.
