| 英文摘要: |
| The work aims to improve the production and processing accuracy of grinding ball screws for machine tools and enhance the accuracy retention and service life of ball screws for machine tools. The induction hardening hardness and effective quenching layer depth of ball screw blanks were confirmed according to different specifications of grinding screws used in machine tools. Commonly used grinding ball screw materials 4150 and GCr15 were used for sensor structure design research and finite element software COMSOL was adopted for electromagnetic simulation to concentrate the magnetic field of the sensor on the surface of the workpiece. The sensors were designed for the same specifications of 4150 and GCr15 materials for surface induction hardening and the differences in induction hardening between the two different materials were studied. By using the designed sensor for quenching process experimental research, it was found that two types of ball screws with the same hardening layer depth required different quenching processes. The induction hardening process of 4150 and GCr15 rod materials is studied. The research results can provide a theoretical basis of the sensor design for producing ball screws of different materials, improve the quenching accuracy of ball screw blanks, and contribute to enhancing the production accuracy and accuracy retention of grinding screws for machine tools. |
