Secondary machining coaxial bore clamp
When the factory produces the steering rocker shaft of the BJ130 steering machine (see Figure 1), it encounters the problem of secondary turning coaxial bore. The material of the rocker shaft is 18GrMnTi, and the hardness of the carburizing and quenching is required to be HRC58-64 at the tooth portion and the journal, and φ18±0.10mm and the carbon fiber and the spline are not carburized and quenched. It is very unstable to protect the processing technology with anti-seepage coating. We use the residual carbon layer and the method of removing the carburized layer by second turning after carburizing to ensure the quality of heat treatment, but this process is machining. It is difficult to guarantee the coaxiality of φ18±0.10mm with the tooth
