[0002] Metal bar can refine its internal grain during heat treatment, improve the hardness and strength of material, and can effectively improve the toughness of material. Unlike the heating mode of traditional heat treatment, induction heating can fine-tune and accurately control the heating process by adjusting the current, voltage and frequency in the induction coil, so induction heating is more and more widely used in metal heat treatment. Metal bar is placed in the center of induction coil during heating process, which can make the metal bar heat more evenly and the heating effect better, so the metal bar should be positioned and clamped in the center of induction coil during induction heating process. Therefore, it is necessary to develop a metal bar induction heating positioning device.

The positioning principle of the device is to adjust the third telescopic adjusting rod to make the adjusting head touch the inner wall of the outer circle of steel pipe, and the position of the third telescopic adjusting rod can be fixed by rotating the nut, so as to realize the positioning of the center of steel pipe. This positioning device is simple to operate, but the positioning accuracy is limited by observing the position through the scale on the adjusting rod, and the positioned steel pipe cannot move axially, which is difficult to adapt to the working condition of induction heating.
