When the upwardly moving quenching table 18 drives the bearing ring body 4 to move upward, when the bearing ring body 4 moves to the groove 22, the operator can only turn off the motor 11, and then the operator can continue to control the electric telescopic rod 19 to rise, so that the quenching table 18 after quenching is rotated, so that the bearing ring body 4 and the impurities generated during quenching move out of the groove 22 under the action of their own gravity and then fall on the conveying plate 23. Because the conveying plate 23 is set to an inclined shape and is provided with a mounting hole, the bearing ring body 4 falling on the conveying plate 23 The ring body 4 can slide along the conveying plate 23, and at the same time, impurities and the quenching agent carried by the bearing ring body 4 fall into the interior of the recovery box 24 from the mounting hole opened in the conveying plate 23, and the impurities are filtered by the filter net 25 inside the recovery box 24, and the quenching agent falls to the bottom of the recovery box 24 through the filter net 25, so that the impurities generated by the bearing ring body 4 can be filtered, and the quenching agent can be collected for the convenience of the operator to take.
