[0002] The shaft class spare concentricity detection frock is a tool or equipment combination for accurately measuring the concentricity of shaft class spares. Its design and use are crucial to ensuring the quality and performance of shaft class spares. The concentricity detection frock usually includes multiple parts, such as a reference seat, a positioning device, a measuring instrument, etc. These parts work together to ensure the accuracy and reliability of the measurement. The specific working principle may involve placing the shaft class spare in the positioning device and then measuring its concentricity through the measuring instrument.
[0003] Currently, the concentricity detection frock faces some significant challenges. The most prominent problem is its difficulty in adapting to the positioning of shaft class spares of a wide range of sizes. This means that when different sizes of shaft class spares need to be detected, the frock may need to be adjusted or even replaced, which undoubtedly increases the complexity and cost of operation. In addition, the positioning restriction effect of the frock is often unsatisfactory without damaging the surface of the spare, which may affect the accuracy of the measurement.
