[0003] The current industry of big machine crankshaft blank axial dimension detection still mainly uses manual hand-held gauge detection. In the actual operation process, the operator needs to complete the workpiece fixing and size measurement tasks at the same time. Due to the lack of standardized fixing tooling, manual fixing of workpieces cannot establish a stable and unified detection reference, so that the measurement results fluctuate greatly each time, and the measurement repeatability cannot be guaranteed. In addition, long-term high-intensity synchronous workpiece fixing and size measurement operation is easy to cause visual fatigue and hand shaking of the operator, resulting in frequent human measurement errors such as reading deviation and gauge placement angle deviation during the measurement process. More worth noting is that this detection mode highly dependent on manual operation not only consumes a lot of human resources, but also its detection efficiency is far lower than the high-efficiency demand of modern manufacturing industry for mass production. In the rapid development of intelligent manufacturing, the traditional manual detection method has been difficult to meet the detection requirements of high precision, high efficiency and high adaptability, and innovative detection technology and method are needed to break through the existing detection bottleneck and promote the big machine crankshaft blank manufacturing to automation and intelligence.
