できなかつた。 Conventionally, there has been known a restraining device for a rotating guide bush which is configured to connect a main shaft and a guide bush so as to transmit the rotation of the main shaft to the guide bush. There is. What is disclosed in this publication is that a guide groove parallel to the center line of the spindle is formed on the outer circumferential surface of the presser nut of the collector chuck of the main spindle, and a guide groove is formed on the inner surface of a cylindrical member fixed to a sleeve holding the guide bush, so that the guide bush slides in the guide groove. The rotation of the main shaft is transmitted to the guide bush by the engagement between the guide groove and the engagement member. This device was developed for turning long, slender round members, and can be used without any problems for cutting materials with a circular cross section. However, the present inventor has found that this device is extremely inconvenient for materials with cross-sections of different diameters, such as hexagonal or square cross-sections. That is, in the case of materials with different diameter cross-sections, the cross-sectional shape of the main shaft's collector chuck and guide bush is the same as that of the materials with different diameter cross-sections,
These angular positions (hereinafter referred to as phases) must match accurately, but conventional devices cannot adjust this phase and cannot be used for materials with cross-sections of different diameters.

いる。 A guide tube 10 is attached to the sleeve 8 holding the guide bush 6. The guide tube 10 is attached concentrically to the centerline of the main shaft 1 and has a cylindrical wall 11 surrounding the chuck nut 5.
Two guide grooves 12 (see FIG. 2) and two working windows 13 are formed in this cylindrical wall 11, which are parallel to the center line of the main shaft. A key 14 is provided between the guide tube 10 and the sleeve 8 to regulate the angle at which they are attached and to ensure rotational transmission. On the other hand, a rotating plate 15 is attached to the front surface of the chuck nut 5 with screws 16. As shown in FIG. 2, the turning plate 15 has a pair of claws 17, each of which extends into the guide groove 12 of the cylindrical wall 11. As shown in FIG. Thus, the turning plate 15 transmits rotation to the guide cylinder 10 by the pawl 17 and the guide groove 12, but is movable in the axial direction with respect to the guide cylinder. Turning board 1
5 further has an arc-shaped elongated hole 18 through which a screw 16 is passed, so that the mounting angle of the turn plate 15 with respect to the chuck nut 5 can be adjusted.

むことにより行われる。 Next, the operation of the above device will be explained. As shown in FIG. 1, when the rod-shaped material 2 is gripped by the collection chuck 3 and inserted into the guide bush 6, the main shaft 1 is rotated. 14, it is transmitted to the guide bush 6 via the sleeve 8, and the guide bush 6 rotates in synchronization with the material 2. At the same time, when the main shaft 1 is advanced, the pawl 17 of the turning plate 15
slides within the guide groove 12. In this way, only the rotation of the main shaft 1 is transmitted to the guide bush 6, and the guide bush is rotationally driven in synchronization with the main shaft 1 and the material 2. By the way, in order to attach the materials 2 having different diameter cross sections to the collection chuck 3 and the guide bush 6 of the main shaft 1, it is necessary that the phases of the two be accurately matched. For this purpose, it is necessary to accurately align the phases of all the members interposed between the collector chuck 3 and the guide bush 6. However, since the main shaft 1 and the chuck nut 5 are connected by threaded engagement, it is practically impossible to attach the chuck nut 5 to the main shaft 1 in a predetermined phase. Therefore, in the present invention, the mounting angle, that is, the phase, of the rotary plate 15 relative to the chuck nut 5 can be adjusted. This phase alignment adjustment is performed when changing from a round bar material to a square material. That is, the collector chuck 3 and guide bush 6 are selected that match the cross-sectional shape of the square material, and these are attached to predetermined locations. A square material is passed through the collector chuck 3 and the guide bush 6, and the chuck nut 5 is attached to the main shaft 1, and the guide tube 10 is attached to the sleeve 8 with a key 14, with the phases of the two matched. Next, the main shaft 1 is advanced, and with the pawl 17 of the turning plate 15 fitted into the guide groove 12, a tool is inserted through the work window 13 to tighten the screw 1.
6 connects the turning plate 15 to the chuck nut 5. Also, when making fine adjustments to the phase, use the spindle 1
1 to the right from the position shown in FIG. This is done by tightening 16 again.

る。 As explained above, in the present invention, the pawl 17 of the turning plate 15 fixed to the chuck nut is configured to slide within the guide groove of the guide tube fixed to the sleeve holding the guide bush, so that it moves in the direction of the center line. Only the rotation of the main shaft 1 that rotates while rotating can be transmitted to the guide bush. Moreover,
The mounting angle of the chuck nut and turning plate can be adjusted, so the phase of the collet chuck and guide bush can be precisely aligned.
It can be used well for materials with different diameter cross sections.
