Study on In-situ Automatic Measuring System of Discontinuous Inner Hole for Aeronautical Precision Coupling
The inner hole of the valve sleeve of the aeronautical precision coupling is discontinuous ， slender and small, its dimensional and geometry accuracy is very high, and its machining accuracy has a significant influence on the assembly accuracy, employment performance and life-span of the precision coupling. Few effective in-situ measuring method is applied in machining site at present, that results in poor assembly quality and low assembly efficiency. A new in-situ measuring method for machining accuracy of precision coupling based on TRIZ ， ultra-precision air gauge and virtual instrumentation is proposed. An in-situ automatic inspection system to measure the inner diameter, roundness and taper of valve sleeve is designed and implemented. Compared with manual measuring method, this automatic inspection system is faster and more accurate, achieving a precision within 0.5μm. It has been applied in match grinding, and the assembling eligibility rate of precision coupling is
