中心に近付くよう形成されている。Next, the auxiliary shaft 11'115 is a hollow shaft, into which the main shaft 4 is fitted, and supports the main shaft 4 in a freely rotatable manner. Furthermore, three arcuate cam grooves 10a are formed in the cam plate 10 bolted to the end surface of the auxiliary shaft. As shown in FIG. 2, this arc-shaped cam groove 108 is formed so that as it goes counterclockwise along the cam groove 10a, it approaches the center of rotation of the cam plate 10.

The three slide tables 12 are slidably supported by the corner slides 11a. A roller 48 that engages with a cam groove 108 formed in the cam plate 10 is provided on the cam plate 10 side of the sliding table 12. As a result, when the cam plate 10 is rotated clockwise with respect to the face plate 11, the cam groove 10
The slide table 12 slides toward the center of rotation of the main shaft 4 by the roller 48 engaged with the roller 8 , and the drawing tool 16 attached to the slide table 12 also moves once toward the center of rotation of the main shaft 4 .

It is configured to move towards. Also, tube W

回転数で回転されるため、摺動台１２は摺動しない。The processing steps for this fixed tube W will be explained below. The main shaft 4 is rotated by the main drive motor 3, and the auxiliary drive motor 4
4 is stopped, the main shaft 4 and the auxiliary shaft 5 are rotated in the same direction and at the same rotation speed by the differential planetary gear device 6. Therefore, at this time, since both the cam plate 10 and the face plate 11 are rotated in the same direction and at the same rotation speed, the sliding table 12 does not slide.
次に、主軸４が回転され、しかも補助駆動モータ４４も

助軸５との間に回転差が生じる。Next, when the main shaft 4 is rotated and the auxiliary drive motor 44 is also rotated, a rotation difference is generated between the main shaft 4 and the auxiliary shaft 5 by the differential planetary gear device 6.
例えば、上記のごとく、共に右回転で、主軸４が１１０

れる。For example, as shown above, both rotations are clockwise, and the main shaft 4 is 110 degrees.
00rD, when the auxiliary shaft 5 is accelerated to 11002 rpm, a relative rotation difference occurs between the face plate 11 and the cam plate 10. This is the same as when the cam plate 10 rotates clockwise with respect to the face plate 11 and the rotation speed is 2 rpm. Therefore, the sliding table 12 engaged with the cam groove 10a of the cam plate 10 by the roller 48 is slid toward the center of rotation of the main shaft 4, and the drawing tool 16 attached to the first sliding table 12 is inserted into the pipe W. Being pushed.

Ｗから離され、絞り工具１６が元の位置に戻される。When one movement of the I-adjustment table 12 is completed, the auxiliary drive motor 44 is rotated in the reverse direction in order to return the drawing tool 16 to the position before machining. At this time, for example, as shown above, both are rotating,
The main shaft 4 is decelerated to 1100 Orp, and the auxiliary shaft 5 is decelerated to 998 Orp.
rpm, it is the same as when the cam plate 10 rotates counterclockwise with respect to the face plate 11 and the rotation speed is 2 rpm. Therefore, the sliding table 12 is driven in a direction away from the rotation center of the main shaft 4, the drawing tool 16 attached to the driving table 12 is separated from the workpiece W, and the drawing tool 16 is returned to its original position.

Further, by reciprocating the spindle device 1 by means of feeding devices (not shown), both ends of the tube W can be processed simultaneously, and the drawing tool 16 can also be pressed against the tube W while sliding. This makes it possible to easily process a tapered shape.

ない。As described above, according to the present spindle device, it is possible to slide the drawing tool 16 toward the rotation center of the spindle 4 while rotating it, and moreover, by setting the rotation speed of the auxiliary drive motor 44 to an arbitrary rotation speed. , the sliding table 12 can be suitably slid at any speed. Thereby, necking processing, cutting, etc. can be suitably performed. Furthermore, since the slide table 12 is perturbed by one movement by the cam, there is little play.

摺動台のガタが少ないという効果も奏する。Effects of the Invention As detailed above, according to the spindle device of the present invention, it is possible to slide toward the center of rotation of the spindle while rotating the gear, and moreover, one of the internal gears can be rotated arbitrarily. By rotating it several times, it is possible to slide the first moving base at an arbitrary speed. This also brings about the effect that necking, cutting, etc. can be suitably performed. Furthermore, since the transmission mechanism is a cam, there is also the effect that there is less backlash in the slide table.
