特にその機構が簡単であり且つ操作を迅速確実に
なし得ることを特徴とする。[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a rotary chuck mechanism that can hold and rotate a soft material such as straw so that it approximates the center line of rotation of the rotary chuck as much as possible.
In particular, the mechanism is simple and can be operated quickly and reliably.
従来の技術

穴に挿入された処理物を固定する構成である。Conventional technology Conventionally, typical rotary chucks that hold the workpiece on the rotation center line of the chuck body are those used in machine tools such as lathes, and these rotary chucks have a cylindrical shape A hole is formed in the center of the main body along the rotation center line, and a plurality of clamping claws are provided that move centripetally in synchronization along a plane perpendicular to the rotation center line from the center of the hole, and The clamping claws are moved by rotating a clamping claw operating shaft on the circumferential surface of the cylindrical body using a separate handle, thereby fixing the object to be processed inserted into the hole.

がある。 In addition, as shown in Fig. 5, other types of rotary chucks that the inventor has conventionally used in order to fix the soft processed material on the rotational center line of the chuck body are A cut 32 of an arbitrary width and arbitrary depth is made in the peripheral wall of the rotating cylindrical body 31 in a direction perpendicular to the length direction of the rotating cylindrical body 31, and a blocking plate for pressing the soft material to be processed is fitted into the cut 32. There is one in which a soft processed material inserted into a hole in the cylindrical body 31 is fixed.
考案が解決しようとする問題点
しかしながら、上記した旋盤等に使用される回
転チヤツクにあつては、軟質処理物を固定するに
は余りにも構造複雑で重厚に過ぎ、且つチヤツク
操作に時間がかかり非能率的であるという不便が
ある。Problems to be Solved by the Invention However, the rotary chucks used in the above-mentioned lathes, etc., have a structure that is too complex and heavy for fixing soft objects, and chuck operation is time-consuming and difficult. It has the disadvantage of being efficient.
一方、細径の回転円筒体を使用した回転チヤツ

さに強度上からの限界があつて一定深さよりも深
く出来ないため軟質処理物の量が少なくなれば遮
断板がそれを穴内の周壁に押圧できなくなつて軟
質処理物の固定が困難になる等の不都合がある。 On the other hand, in the case of a rotary chuck that uses a small-diameter rotating cylindrical body, it is possible to fix the soft processed material in a fixed position, but the soft processed material inserted into the hole of the rotating cylindrical body is blocked by the blocking plate inside the hole. Because it is pressed flat against the peripheral wall of the rotating cylinder, it is difficult to fix it accurately at the center of rotation, and there is a limit to the cutting depth of the rotating cylindrical body from the viewpoint of strength, so it cannot be deeper than a certain depth. If the amount of the soft material to be treated decreases, the blocking plate will not be able to press it against the peripheral wall of the hole, making it difficult to fix the soft material.
本考案は上記不具合点を解消するために、藁等

回転体３の回転中心線と略一致するようにする。 That is, as shown in FIGS. 2 and 3, a rotary body 3 supported so as to be able to rotate at a fixed position is provided with a support shaft 5 that moves together with the rotating body 3, and a plurality of shafts with the support shaft 5 as the center of rotation are provided. Soft material holding arms 4, 4
are arranged in a crisscross pattern, and the soft processing object holding arms 4,
On one side of 4 are formed clamping parts 8, 8, and on the other side are clamping part opening/closing arms 6, 6 which are pivotally connected to the rotary drive shaft 7 so that one side can transmit rotation. The clamping parts 8, 8 are provided with a cylinder 20 which is pivotally mounted so that the rotation of the rotary drive shaft 7 is transmitted to the clamping parts 8, 8, and further displaces the rotary drive shaft 7, and which is brought into a clamping state by the displacement of the rotary drive shaft 7. The position of the rotating body 3 is made to substantially coincide with the center line of rotation of the rotating body 3.

８，８は軟質処理物を開放する。Operation The cylinder 20 causes the rotary drive shaft 7 to rotate to the rotating body 3.
When displaced in the direction, the distance between the rotational drive shaft 7 and the support shaft 5 is reduced, and the clamping part opening/closing arms 6, 6 and the soft processing material clamping arms 4, 4 are bent into a pantograph shape at their pivot points. . As a result, the intersecting angles of the soft object holding arms 4, 4 are widened, and the holding parts 8, 8 release the soft object.

が速やかに行われる。 Conversely, when the rotary drive shaft 7 is displaced in the direction opposite to the rotating body by the cylinder 20, the clamping parts 8, 8 clamp the soft processed material. The clamping force of the soft material clamping arms 4, 4 is proportional to the force with which the cylinder 20 displaces the rotary drive shaft 7, and can be freely adjusted by appropriately changing the pressure of the working fluid (for example, air, oil, etc.) in the cylinder 20. be done. Furthermore, unlike the clamping force produced by screws or the like, a constant clamping force is always exerted as long as the pressure of the working fluid acts on the cylinder 20 even if the soft object is deformed. In addition, driving by the cylinder 20 allows the clamping parts 8, 8 to be opened and closed more quickly than by screws.

回転中心に近接するように変化するのみである。 Furthermore, the rotation of the rotary drive shaft 7 is transmitted to the soft processing material holding arms 4, 4, the rotary body 3, etc. through the holding part opening/closing arms 6, 6, and the rotation is transmitted to the holding parts 8, 8 at the end.
Rotate 8. These clamping parts 8, 8 rotate approximately in alignment with the rotation center position of the rotating body 3 under the state in which the soft processing material is clamped, and even if the soft processing material is flattened by the clamping parts 8, 8, the soft processing material clamping arm Even if the intersection angle of 4 and 4 becomes smaller, the soft processed material only moves closer to the center of rotation of the rotating body 3.

Since the center of the soft object is approximately aligned with the center and the clamping force is obtained by the displacement force of the rotary drive shaft of the cylinder, even if the soft material to be processed becomes flattened in the clamping section, the center of rotation will not separate from the center of rotation of the rotary chuck, and the center of rotation will not separate from the center of rotation of the rotary chuck. The soft material to be processed is always clamped with a constant clamping force as long as the working fluid at a constant pressure is acting within the cylinder, which has the effect of reliably preventing problems such as the soft material spinning in the clamping section. .
