Precision Measurement and Error Evaluation of Connecting Rod Standard Gauge Block Based on CMM

Abstract:

Connecting rod is often in high speed movement as one of the main parts of automobile engine. It’s shape error and accuracy of the hole or the plane will directly influence the working performance and the service life of engine. So the production has very strict requirements on the shape error. Connecting rod standard gauge block, as a standard part of manufacturing connecting rod, it’s manufacturing accuracy is higher, and the measurement and calibration of error directly affects the machining efficiency and the precision of the connecting rod. CMM develops so fast that constantly pounding all kinds of special measuring equipment. In the contact, a digital measurement is carried out for the key dimension and the space shape error of connecting rod standard gauge block. so data processing of the measuring results has been obtained, then reconstructed geometry elements of the plane and round hole ,etc., and got the required shape error by the contact CMM, it provides the basis for improving machining precision of the connecting rod.
