Design of piston shape accuracy checking fixture
Abstract
The quality of piston is determined by mechanical manufacturing process level,and the detection means is the important part to ensure the quality of products and components.The quality of the piston can not meet the design requirements, the size, shape, position tolerance inspection is the essential procedure.The application of the modern engine is more and more wide, and it is very important to improve the reliability of the piston. This is based on the design of this test.
In this paper, I design two kinds of shape - position accuracy fixture: Pin hole perpendicularity seized on the skirt with the axis and The symmetry checking of the axis of the skirt with pin hole axis.Focus on solving the verticality and the symmetry detection of piston pin holes.
Key word : Piston ; Shape and position accuracy ; Checking Fixture
