The rotary motion unit 80 rotates the disk-shaped cutting tool 50. Therefore, the disk-shaped cutting tool 50 allows the outer surface of the cylindrical material W between the chuck 22 and the rotation support 30 to be cut. Thereby, the tooth shape of the long-sized worm can be formed on the outer surface of the cylindrical material (W).

Referring again to FIGS. 3 to 5, the long-sized worm cutting unit 40 holds the disc-shaped cutting tool 50 with respect to the cylindrical material W between the chuck 22 and the rotary support 30. It is provided with a tilting motion unit 90 for tilting motion at an angle.

The tilting movement part 90, the cutting tool support arm (axially rotating with respect to the cylindrical material (W) between the chuck 22 and the rotary support 30 in a state vertically supporting the disk-shaped cutting tool 50 ( 64), and a tilting motor (92) for axially rotating the cutting tool support arm (64).

The tilting motor 92 is built in the support 62 and rotates the cutting tool support arm 64 at a specific angle around the horizontal axis L2. Accordingly, the disk-shaped cutting tool 50 installed on the cutting tool support arm 64 can be tilted.

As a result, the disk-shaped cutting tool 50 tilted at a constant angle makes it possible to cut gear teeth having a constant angle on the outer surface of the cylindrical material W while rotating. As a result, a tooth shape of a long worm having a lead angle of a certain angle is formed on the outer surface of the cylindrical material W.

In addition, the long-sized worm cutting unit 40 includes a swing motion part 100 that swings the disk-shaped cutting tool 50 relative to the cylindrical material W between the chuck 22 and the rotating support 30. .

The swing motion part 100, to the horizontal transfer platform 72 in a state that horizontally supported the cutting tool support arm 64 and the cutting tool support arm 64 for supporting the disk-shaped cutting tool 50 It comprises a support 62 that is rotatably installed around the vertical axis (L1), and a swing motor (102) for rotating the support 62 around the vertical axis (L1).

The swing motor 102 is installed on the horizontal transfer platform 72, and rotates the support 62 around the vertical axis L1. Accordingly, the cutting tool support arm 64 horizontally installed on the support 62 and the disk-shaped cutting tool 50 installed on the cutting tool support arm 64 can swing around the vertical axis L1. do.

As a result, the disk-shaped cutting tool 50 swinging around the vertical axis L1 moves to correspond to the concave long curvature of the cylindrical material W supported between the chuck 22 and the rotating support 30. While cutting.

As a result, it is possible to form a spiral tooth on the concave long outer surface of the cylindrical material (W).

Next, a method of manufacturing a long-sleeved worm using the long-sleeve worm manufacturing apparatus according to the present invention will be described in detail with reference to FIG. 6.

First, as shown in Figure 6 (a), after fixing one end of the cylindrical material (W) to the chuck 22, and the other end is supported by the center member (C) of the rotary support 30, the chuck 22 ).

Subsequently, as shown in FIG. 6 (b), the cutting tool T is used to concave the cross section of the cylindrical material W so that the cross section decreases from both ends toward the central portion, so that the long material W1 is formed. It is possible (S10). Here, the (S10) step is preferably made in another machine tool such as a lathe.

When the cutting of the long-form material W1 is completed, as shown in FIG. 6 (c), the position of the disk-shaped cutting tool 50 of the long-form worm cutting unit 40 is forward, backward, left, and right. Adjust to align with the long-sized material (W1) (S20).

At this time, the position adjustment of the disk-shaped cutting tool 50, as shown in FIGS. 3 and 4, uses the horizontal transfer unit 72 and the vertical transfer unit 74 of the position adjustment unit 70.

And when the alignment of the disk-shaped cutting tool 50 is completed, as shown in FIG. 6 (d), the disk-shaped cutting tool 50 is swinged in the horizontal direction to move to one side of the long-form material W1 Order. That is, the disk-shaped cutting tool 50 is aligned to the position where the gear teeth start.

At this time, the disc-shaped cutting tool 50 is tilted at an angle with respect to the long material W1 (S30). That is, it is tilted at an angle corresponding to the lead angle of the tooth to be formed in the long-form material W1.

Here, the tilting operation of the disk-shaped cutting tool 50 may be performed in step S20.

When the tilting of the disk-shaped cutting tool 50 is completed, as shown in FIG. 6 (e), the chuck 22 is rotated to rotate the long-sized material W1. Then, while rotating the circular cutting tool 50, the circular cutting tool 50 is swinged in the horizontal direction (S40).

Then, while the disk-shaped cutting tool 50 moves correspondingly to the concave outer surface of the long material W1, as shown in Fig. 6 (f), the concave outer surface of the long material W1 is cut to form gear teeth. To form.

In particular, the disk-shaped cutting tool 50 rotates in response to the concave outer surface of the long-sized material W1 in a tilted state at a constant angle and swings in the horizontal direction. Accordingly, the gear teeth can be formed by only one cutting operation.

When the gear tooth cutting is completed, the long-sized worm 1 as shown in FIG. 6 (g) can be finally manufactured.

On the other hand, in the step S40, by using the position adjustment unit 70 (see FIGS. 3 and 4), the disk-shaped cutting tool 50 can be moved forward and backward with respect to the long material W1, Through, it is possible to adjust the cutting depth of the disk-shaped cutting tool 50 for the long material (W1).

In particular, by adjusting the cutting depth of the disc-shaped cutting tool 50 with respect to the long-form material W1, the depth of the teeth of the gear formed in the long-form material W1 can be adjusted.

In addition, the rotary movement unit 80, the swing movement unit 100 and the chuck driving unit (not shown) are configured to be synchronized with each other. Therefore, the rotational speed of the disk-shaped cutting tool 50, the rotational speed of the swing, and the rotational speed of the chuck 22 are synchronized with each other according to the gear structure of the worm to be manufactured.

Particularly, a long-formed worm having a specific reduction ratio by the rotational speed and swinging speed of the disk-shaped cutting tool 50 synchronized with each other according to the gear reduction ratio of the worm to be manufactured, and the rotational speed of the chuck 22 Can be precisely manufactured.

Since the rotation synchronization device itself is a known technique, detailed description thereof will be omitted.

According to the apparatus and method for manufacturing a long-sleeved worm having the above-described configuration, the long-sleeved worm is cut while the circular cutting tool 50 rotates while rotating at a predetermined angle while swinging in the horizontal direction. Due to the structure, it is possible to rapidly manufacture a high-precision long-sized worm with low cost and high efficiency, compared to the conventional method using an expensive 5-axis machine.

In particular, since the disk-shaped cutting tool 50 rotates to correspond to the concave outer surface of the long-sized material W1 and swings at the same time to form a gear tooth with only one cutting process, a high-precision long-formed worm Can be produced very quickly.

In addition, since the high-precision long-formed worm can be manufactured quickly and at low cost and with high efficiency, productivity can be greatly reduced by significantly shortening the processing time of the long-formed worm, thereby significantly reducing manufacturing cost.
