摘要
HSK shank is the most widely used shank in high speed machining recently, the key dimensions' measurement technology of which decides the level of its manufacture precision. How to accomplish the dimensions' measurement for HSK shank quickly and accurately is crucial for improving its manufacture level. In order to solve this problem, a kind of special measuring gauge for HSK shank is developed. A novel and simple positioning device is developed according to the idea of limiting shank's degrees of freedom, which is the most important component and affects measuring precision greatly. It is pointed out that positioning device is a major factor which leads to the generation of system error. By means of theoretical analysis and computing errors derived from various deviation of each transducer relative to its theoretical installing location are studied in detail, by experimental measuring and data computing random errors are analyzed accurately. Error transmission on indirectly measured dimension and measurement standard uncertainty of key dimensions are studied respectively. Research shows that measuring precision of the gauge meets the requirement of high-precision measurement for HSK shank's key dimensions.
