Technical Field

This machine tool is different from conventional mechanical transmission or hydraulic transmission, and is mainly designed for high-frequency, dual-frequency, supersonic frequency, and medium-frequency quenching. It has high positioning accuracy and adopts CNC programming to adjust the quenching depth by changing the rotation speed and movement speed of the workpiece according to different outer diameters during quenching.

[0004] When shaft parts pass through the induction coil, they will be subjected to high-temperature heat treatment.

[0032] Working principle: the control host 1 is based on the CNC system and uses the PLC controller to realize the automatic program control of the machine tool. It is already one of the well-known technologies in the prior art, so it will not be described in detail in this case. The crossbeam 2 is used to carry the loading and unloading mechanism 3 and the temperature control mechanism 4. In the loading and unloading mechanism 3, the electric push rod can be controlled to move up and down, thereby driving the installation frame 1 35 and the installation frame 2 36 to move, so that the groove can be opened to remove the conductor block 43 therefrom, and the actual size of the current shaft part 15 can be matched to replace the coil frame 41 with a suitable inner diameter, and the suitable coil frame 41 is inserted into the corresponding groove through the conductor block 43.

The hydraulic rod 7 is driven down by the support arm 6, and the crossbeam 2 is driven down, so that the induction coil 42 located at the bottom is preheated first through the outer wall of the shaft part 15, and the induction coil 42 located at the top is followed by The outer wall of the preheated shaft part 15 is heated. At the same time, the rotating motor works to drive the rotating shaft 13 to drive the turntable 14 to rotate, and drives the clamped shaft part 15 to rotate at a uniform speed, so that each surface of the part can be evenly heated. The anti-sliding block 10 maintains the stability of synchronous clamping by rotating. When the beam 2 drops to the base 11, the heating of the shaft part 15 is completed. At this time, the linear motor 5 resets upward to drive the beam 2 to rise. At the same time, the pump draws water from the nozzle on the water spray pipe 37 to spray the shaft part 15 for rapid cooling.
