Locating Error Analysis of Dimension and Symmetry of the Keyseat on Shaft and Jig Design with Precision

Abstract:

Keyseat on the shaft is an important geometry and is increasingly required for the dimension and symmetry with strict tolerance. However, the routine milling operation for the keyseat is done with the shaft located on V block, with relatively low accuracy. In the current study, based on analysis of the influencing factors of the locating errors for three types of design, a special jig is designed that mey supply high locating accuracy with ease in operation. The jig is composed of the base, assembly of position parts, supporting plate and V block, linkage-clamping mechanism. Positioning errors and clamping force are insighted. Thus, theoretically-zero-locating error jig is created with efficiency and ease in operation.
