Induction quenching machine tool with double-frequency heating power source

The invention relates to the technical field of quenching machine tools, and discloses an induction quenching machine tool with a double-frequency heating power source. The induction quenching machinetool comprises a workbox. A first motor is fixedly mounted on the top of the side face of the workbox, a fixing box is arranged on the top of an inner cavity of the workbox, and an output shaft of the first motor is fixedly sleeved with a lead screw located in the fixing box. According to the induction quenching machine tool with the double-frequency heating power source, two sets of draught fansare started, smoke dust generated when a workpiece is heated and quenched is absorbed through an air flue, the smoke dust generated during quenching is purified through a smoke dust purification device connected with air outflow pipes of the two sets of draught fans, meanwhile, one set of draught fan can be driven to extract cold air from the external environment, the cold air is conveyed into the workbox through the air
