Next, the motor 169 is supported to the housing 110 to rotate the bolt rod 167.

The horizontal transfer member 160 is configured such that the bolt rod 167 is rotated by the rotation of the motor 169, the bolt rod 167 will be rotated in place since both ends are supported by the bearing 168, The coupled nut 166 and the moving plate 164 attached to the nut 166 are not connected to the second guide rail 162 via the second guide clip 163, and thus, may not be rotated and may slide stably. .

"A" and "B" of Figure 7 is a schematic perspective view showing the operation of the mounting member and the vertical lifting member according to an embodiment of the present invention.

First, referring to "A", the support plate 142 of the mounting member 140 is attached to the bolt rod 155 of the vertical elevating member 150. The first guide clip 154 of the vertical elevating member 150 and the first guide rail 148 of the mounting member 140 are coupled to each other.

Now, referring to "I", the rotating body 153 coupled to the belt 156 by the rotation of the motor 158 of the vertical elevating member 150 starts to rotate in place, and the rotating body 153 It can be seen that the bolt rod 155 is screwed to the) and the mounting member 140 attached thereto are raised.

That is, the bolt rod 155 is attached to the support plate 142 of the mounting member 140, the mounting member 140 to the first guide clip 154 via the first guide rail 148. Since it is coupled to the rotating body 153 is to be rotated without being rotated.

On the other hand, the mounting member 140 is coupled to the first guide clip 154 may be raised more stably by the first guide rail 148 is raised to guide.

In addition, when the motor 158 of the vertical lifting member 150 is rotated in reverse, the bolt rod 155 and the mounting member 140 which have been raised will be lowered at the same time.

"A" and "B" of Figure 8 is a schematic perspective view showing the operation of the vertical elevating member and the horizontal conveying member according to an embodiment of the present invention.

First, referring to "a", the support plate 151 of the vertical elevating member 150 is attached to the upper surface of the movable plate 164 of the horizontal conveying member 160. Of course, since the cutting hole 165 is formed in the movable plate 164, the bolt rod 155 of the vertical elevating member 150 may extend downward. Of course, since the mounting hole 114 is formed in the housing 110 in which the horizontal transfer member 160 and the vertical lifting member 150 are to be mounted, there is no interference in the installation and operation of the bolt rod 155. .

Now, referring to "I", the bolt rod 167 starts to rotate in place by the rotation of the motor 169 of the horizontal transfer member 160, the nut is coupled to the bolt rod 167 It can be seen that 166 and the moving plate 164 attached to the nut 166 and the vertical lifting means 150 attached to the moving plate 164 simultaneously slide forward. That is, even though the bolt rod 167 is rotated, the nut 166 and the movable plate 164, which are screwed thereto, are coupled to the second guide rail 162 via the second guide clip 163. It will not rotate with the rod 167 and will slide forward.

In addition, when the motor 169 of the horizontal conveying member 160 is rotated in reverse, it is natural that the nut 166, the moving plate 164, and the vertical elevating member 150, which have been slid forward, will slide back again. .

Here, although not shown, the mounting member 140 attached to the bolt rod 155 of the vertical elevating member 150 also has the nut 166 and the movable plate 164 and the vertical elevating of the horizontal conveying member 160. It is too obvious to slide with the member 150.

9 is a schematic longitudinal cross-sectional view showing the entire operation of the gear tooth high frequency heat treatment apparatus of the ring gear according to the preferred embodiment of the present invention.

First, referring to "A", the heating / cooling means 120 is mounted on the upper end of the frame 112 of the housing 110, and the ring gear mounting means 130 is installed on the upper plate of the housing 110. . Of course, the heating / cooling means 120 is connected to the high frequency generator 118 and the cooling water supply 119 provided in the housing 110, respectively, although not shown by a schematic longitudinal section, the ring gear mounting means 130 is Three mounting holes 114 formed in the upper plate of the housing 110 are respectively installed.

First, the operator rotates the motor 169 of the horizontal conveying member 160, which is the ring gear mounting means 130, to vertically raise and lower the bearing gear 170 so as to settle it according to the diameter of the ring gear 200 to be heated. The member 150 and the mounting member 140 are slid back and forth to match the diameter gap. Thereafter, the operator places the ring gear 200 on the first rotation roller 146 of the mounting member 140, and the second rotation roller 147 faces the outer surface to prevent the ring gear 200 from falling off. Will be supported.

Now, referring to "I", the ring gear 200 is heated / cooled means 120 to heat-treat the ring gear 200 placed in the first rotation roller 146 of the mounting member 140. The motor 158 of the vertical elevating member 150 is rotated to be adjacent to the bolt rod 155 and the mounting member 140 attached thereto is raised.

At this time, the ring gear 200 and the body 122 of the heating / cooling means 120 may be heated to be the same horizontally, but heat treatment may be performed by dividing the ring gear 200 into two parts, the lower surface and the upper surface. something to do.

Thus, the rising operation is stopped after the upper surface of the ring gear 200 is raised to be adjacent to the high frequency generator 124 of the heating / cooling means 120. Then, the operator rotates the motor 144 of the mounting member 140 through the control unit 170 to rotate the ring gear 200 placed in the first rotation roller 146 in the rotation direction, and at the same time generate high frequency The unit 124 causes the high frequency to be emitted.

Subsequently, referring to "C", after a predetermined time elapses, the operator further rotates the motor 158 of the vertical elevating member 150 in the same direction through the control unit 170 to lower the surface of the ring gear 200. It is positioned to be adjacent to the high frequency generator 124 to radiate high frequency to heat-treat the lower surface. Then, after a predetermined time elapses, the operator rotates the motor 158 of the vertical elevating member 150 in the reverse direction to heat-treat the upper surface of the ring gear 200 again. The heat treatment is performed while repeatedly raising and lowering 200).

Now, when the heat treatment is completed, the operation of the high frequency generator 124 is stopped, the ring gear 200 is positioned adjacent to the coolant spray pipe 126, and then the coolant spray pipe 126 is sprayed with the coolant to be heated. The part is cooled down.

Then, the operator stops the operation of the motor 144 of the mounting member 140, and rotates the motor 158 of the vertical lifting member 150 in the reverse direction to lower the bolt rod 155 and the mounting member 140. And you're done.

Of course, it is too obvious that such a work progress may be set in advance in the controller 170 and may be sequentially performed by the operator's start signal.

According to the gear tooth high frequency heat treatment apparatus 100 of the ring gear of the present invention operated as described above, since the distance can be adjusted by the sliding operation of the horizontal conveying member 160, the mounting member 140 is a ring gear having various sizes Of course, since the mounting member 140 rotates the ring gear 200 and moves up and down by the operation of the vertical lifting member 150, the heat treatment may be performed by placing the heat sink 200 therein. Heat treatment is possible, which can greatly improve work efficiency.
