[0033] A circle of circular holes 8 is formed on the outer edge of the top of the rotating disk 3, and a lifting material loading assembly 7 is installed inside each circular hole 8, and the workpiece is placed on the lifting material loading assembly 7;

[0034] A rotating material assembly 9 for driving the lifting material loading assembly 7 to lift and rotate is installed on one side of the top of the chassis 1 .

[0035] According to an automatic turntable of a high-frequency quenching machine tool in an embodiment of the utility model, a driving motor 94 drives the squeezing roller 96 to rotate, so that the second round block B74 sandwiched between the squeezing rollers 96 on both sides rotates, and then drives the rotating sleeve 71 and the first round block A73 to rotate, so that the workpiece located on the top of the first round block A73 rotates, and the electric telescopic rod B92 continues to extend, and the limiting column 98 moves upward against the movable column 72, so that the workpiece moves upward and enters the inner cavity of the high-frequency coil 6 for heating, so that the workpiece is in a rotating state while being heated by the high-frequency coil 6.
