Crankshaft heat treatment quenching device

Abstract

The utility model discloses a crankshaft heat treatment quenching device which comprises a quenching box, the outer wall of the right side of the quenching box is fixedly connected with a fixing plate, the side wall of the fixing plate is fixedly connected with a motor, the output end of the motor is fixedly connected with a first belt pulley, and the other end of the first belt pulley is fixedly connected with a clamping mechanism for clamping a crankshaft. The clamping mechanism is located in the quenching box, a second belt pulley is arranged below the first belt pulley, a belt is arranged between the first belt pulley and the second belt pulley in a transmission mode, the side wall of the second belt pulley is rotationally connected with the outer wall of the right side of the quenching box, and the other end of the second belt pulley is fixedly connected with a stirring assembly for stirring cooling liquid. By arranging the quenching box, the motor and the clamping mechanism, direct taking-out is facilitated, operation is easy, and the machining efficiency is improved; through the first belt pulley, the second belt pulley, the stirring assembly, the belt, the water pump, the water pumping pipe, the cold water circulating pump and the water conveying pipe, the temperature of cooling liquid is kept uniform, cold water circulation is guaranteed, and quenching efficiency is improved.
