[0001] The utility model relates to the field of quenching machine tools, in particular to a workpiece coaxial lifting mechanism for high-frequency quenching machine tools. Background Art

[0002] Quenching technology is a metal heat treatment process that heats the metal workpiece to a certain appropriate temperature and maintains it for a period of time, and then immerses it in a quenching medium for rapid cooling. Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various tools, molds, gauges and parts that require surface wear resistance, such as gears, rollers, carburized parts, etc.

When the moving seat is in two different positions for operation, the front end of the moving seat is subjected to force, which makes it easy for the connection between the moving seat and the lifting equipment to deform, and the stability of the moving seat cannot be guaranteed.
