The setting of the spring 31 can prevent the workpiece from expanding during heating and causing damage to the limiting part;

[0028] As an embodiment of the present invention, a profiler 20 and a robot arm 21 are arranged above the mounting table 1. An induction heating module 22 is installed at the other end of the robot arm 21. It is a method of heating conductive materials such as metal materials. It is mainly used for metal heat processing, heat treatment, welding and melting. As the name implies, induction heating uses electromagnetic induction to generate current inside the heated material, relying on the energy of these eddy currents to achieve the purpose of heating. The basic components of the induction heating system include an induction coil, an AC power supply and a workpiece. Depending on the heating object, the coil can be made into different shapes. The coil is connected to a power supply, which provides an alternating current to the coil. The alternating current flowing through the coil generates an alternating magnetic field passing through the workpiece. The magnetic field causes the workpiece to generate eddy currents for heating. By using the profiler 20, the shape of the workpiece can be measured and recorded, and the geometric shape data can be imported into the computer for modeling. The Deform software is used to conduct an initial exploration of the high-frequency quenching process parameters, and the process parameters are imported into the robot arm 21 module. This process is all carried out in the processor;

The rotating mechanism includes a first mounting frame 6 installed on the right side of the right vertical plate 3, and a first motor 7 is installed on the first mounting frame 6.

The moving mechanism includes a second mounting frame 14 fixedly connected to the right side of the mounting platform 1, and a second motor 15 is installed on the second mounting frame 14. The second motor 15 is a servo motor that can change the rotation direction. The servo motor can control the speed and has very accurate position accuracy. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has an electromechanical time. The electric motor 15 has the characteristics of small constant and high linearity, and can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. The output shaft of the second motor 15 extends into the slide slot 16 and is fixedly connected with a threaded rod 17. The left end of the threaded rod 17 is slidably connected with the left inner wall of the slide slot 16. The threaded rod 17 is threadedly connected with a slider 18. A cavity 24 is provided in the slider 18. The inner bottom of the cavity 24 is rotatably connected with a second rotating shaft 25. The upper end of the second rotating shaft 25 extends to the outside and is fixedly connected with a connecting strip 19. The front and rear sides of the connecting strip 19 are fixedly connected with the profilometer 20 and the robot arm 21 respectively.

[0032] As an embodiment of the present invention, a second electric telescopic rod 26 is fixedly connected to the left inner wall of the cavity 24 , a rack 27 is fixedly connected to the telescopic end of the second electric telescopic rod 26 , and a gear 28 meshing with the rack 27 is fixedly connected to the second rotating shaft 25 .

[0033] In the present invention, when in use, the workpiece to be processed is placed between the first limit plate 23 and the second limit plate 30, and the first electric telescopic rod 8 is started to push the second connecting plate 29 and the second limit plate 30 to move rightward, and the workpiece is clamped and limited by the second limit plate 30 and the first limit plate 23;

[0034] After the limit is completed, the profiler 20, the second motor 15 and the first motor 7 are started. After the first motor 7 is started, the two first rotating shafts 4 will rotate synchronously through the cooperation of the first pulley 9, the second pulley and the transmission belt 10. The synchronous rotation of the two first rotating shafts 4 will rotate the workpiece, and the start of the second motor 15 will rotate the threaded rod 17, thereby driving the slider 18 to move left.

The staff starts the first motor 7 to rotate again, and starts the robotic arm 21, the induction heating module 22 and the second motor 15 at the same time. When the robotic arm 21 moves to the left, the induction heating module 22 moves back and forth to quench the rotating workpiece surface, thereby achieving a quenching effect on the entire workpiece surface.
