Since the two ends of the shaft are the overall structure of the ball head and the ball socket, the existing technology mostly uses two induction hardening equipment to quench the ends. This requires the configuration of two heat treatment equipment, which has bottlenecks in cost control, quenching quality and efficiency. In addition, there is a high dependence on the operator's experience and skills during the operation, and the phenomena of wrong quenching, repeated quenching, and missed quenching often occur, and the production efficiency is very low.

[0004] To achieve the above-mentioned purpose of the invention, the induction quenching device of the present invention includes a quenching machine, a vibration transformer, a sensor, a scanning probe, a conveying screw, a blanking trough, a heating power supply, a quenching liquid tank, an anti-error feeding device and a control system; two conveying screws are installed in the middle of the quenching machine, the head end of the conveying screw is connected to the anti-error feeding device above it, a scanning probe is arranged above the front section of the conveying screw, and sensors are arranged on both sides of the middle section. The sensor is connected to the vibration transformer and the heating power supply, a blanking trough is arranged at the tail end of the conveying screw, and the quenching liquid tank is installed below the conveying screw.

[0005] Furthermore, the vibration transformer is fixed on the upper part of the heating power supply; the vibration transformer, the sensor, the heating power supply, the quenching liquid tank, the scanning probe and the control system of the quenching machine tool are connected.

[0006] Furthermore, the inductor is a semi-open induction coil.

[0007] Furthermore, the spiral groove of the conveying screw is matched with the diameter of the push rod, and the conveying screw is driven to rotate by the motor inside the quenching machine through the gear continuously variable transmission.

[0009] When quenching the two ends of the push rod, the operator only needs to put the push rod into the error-proof feeding device, start the quenching machine and the heating system, and the push rod will automatically move along the rotating conveying screw to the sensor for continuous heating. By controlling the rotation speed of the conveying screw, the movement speed of the push rod can be controlled to ensure that the push rod is heated to the temperature required by the process; the quenching liquid control solenoid valve signal is given by the scanning probe, and the spray system of the quenching liquid tank can be controlled to spray cold.

[0013] like Figure 1 As shown, the induction quenching device of the present invention mainly includes a quenching machine tool 1 and its control system 10, a vibrator 2, a sensor 3, a scanning probe 4, a conveying screw 5, a blanking chute 6, a heating power supply 7, a quenching liquid tank 8, a protective feeding device 9, etc.

[0014] Two conveying screws 5 are installed in the middle of the quenching machine 1. The spiral groove of the conveying screw 5 is adapted to the rod diameter of the push rod, and the spiral groove is designed according to the ratio of the rod diameter of the push rod. The conveying screw 5 is driven to rotate by the motor inside the quenching machine 1 through the gear continuously variable transmission. The conveying screw 5 adopts a continuously variable transmission. When the conveying screw 5 rotates, the push rod can automatically move axially through its own gravity and the friction force of the spiral groove surface of the conveying screw 5. The head end of the conveying screw 5 is docked with the anti-error feeding device 9 above it; the ball head end and the ball socket end of the blanking port of the anti-error feeding device 9 are respectively adapted to the ball heads and ball sockets at both ends of the push rod. The anti-error feeding device 9 is fixed above the quenching machine 1. Considering the difference in the shape of the ball heads and ball sockets at both ends of the push rod, the heating current is different. The anti-error feeding device 9 mainly uses the difference in the external dimensions of the ball head end and the ball socket end to design the blanking port structure. When the push rod is placed at the wrong head, the push rod cannot be Sliding into the spiral groove of the conveying screw 5 can effectively achieve the error-proofing effect; sensors 3 are provided on both sides of the middle section of the conveying screw 5, and the sensors 3 are semi-open induction coils; the sensors 3 are connected to the oscillator 2 and the heating power supply 7, so that the ball heads and ball sockets at both ends of the push rod are heated when passing through the sensors 3, and the oscillator 2 is fixed on the upper part of the heating power supply 7; a blanking trough 6 is provided at the tail end of the conveying screw 5, and a quenching liquid tank 8 is installed below the conveying screw 5; the scanning probe 4 is installed above the front section of the conveying screw 5. When the push rod passes through the head of the scanning probe 4, the control system 10 will be triggered to control the quenching liquid in the quenching liquid tank 8. The solenoid valve of the control system 10 works, which can realize intermittent liquid spray cooling of the push rod. After the quenching liquid cools the workpiece, it can be returned to the quenching liquid tank 8 for centralized and cyclic use; the oscillator 2, the sensor 3, the scanning probe 4, the heating power supply 7, the quenching liquid tank 8 are connected to the control system 10 of the quenching machine tool 1.
