Description

しかし、特許文献に記載のワーク送出装置は、収納部分と筒部分とが一体であるため、例えばワークの加工に際して筒部分側に振動等が伝導されると、収納部分も振動等することになり、騒音等の他、素材7(ワーク)の収納や補給に対して悪影響を与える場合があるという問題点があった。 However, since the storage part and the cylinder part are integrated in the workpiece delivery device described in Patent Document 1 , for example, when vibration or the like is conducted to the cylinder part side during processing of the workpiece, the storage part also vibrates. In addition to noise, there is a problem that the material 7 (work) may be stored and replenished.

モータ112がワーク収容部110に並設されている。このモータ112の駆動によって回転される螺旋軸113が主軸軸線Cと平行に配置されている。この螺旋軸113に、螺軸113の回転によって螺旋軸113に沿って進退移動するナット113aが螺合されている。ナット113aは、ワーク収容部110に突設された連結部材114の先端に取り付けられている。
上記モータ112,螺旋軸113,ナット113a等によってワーク収容部駆動手段が構成され、モータ112の駆動によって、ワーク収容部110が主軸軸線Cと同方向に進退移動する。
A motor 112 is juxtaposed with the work accommodating portion 110. A helical shaft 113 rotated by driving of the motor 112 is arranged in parallel with the main axis C. This helical shaft 113, a nut 113a which moves forward and backward along the helical axis 113 by rotation of the screw-handed shaft 113 is screwed. The nut 113 a is attached to the distal end of a connecting member 114 that protrudes from the work accommodating portion 110.
The motor 112, the spiral shaft 113, the nut 113a, and the like constitute a work accommodating portion driving means, and the workpiece accommodating portion 110 moves forward and backward in the same direction as the main axis C by driving the motor 112.

[作用]
次に、図3及び図4を参照しながら、上記のワーク供給装置の作用を説明する。
図3(a)に示すように、前記のように作業位置Aでチャック220把持されたワークWは、自動旋盤によって加工される。なお本実施形態においてワーク収容部110は、作業位置AにワークWを供給した後、チャック220に把持されたワークWと、ワーク収容部110の前端との間に隙間が形成されるように僅かに後退する。加えてワーク収容部110は前記のように支持され、軸心を中心として自由に回転することがない。
このため本実施形態の自動旋盤は、ワークWを主軸2と一体的に回転させ、ワーク収容部110内で静止するワークWと非接触状態で安定して加工することができる。またワーク収容部110は、ワークWを静止状態で安定して収容することができる。
[Action]
Next, the operation of the workpiece supply device will be described with reference to FIGS. 3 and 4.
As shown in FIG. 3 (a), the workpiece W held by the chuck 220 in the working position A as described above is processed by an automatic lathe. In this embodiment, after the workpiece W is supplied to the work position A, the workpiece accommodating portion 110 is slightly so that a gap is formed between the workpiece W gripped by the chuck 220 and the front end of the workpiece accommodating portion 110. Retreat to. In addition, the workpiece accommodating portion 110 is supported as described above and does not rotate freely around the axis.
For this reason, the automatic lathe according to the present embodiment can stably process the workpiece W in a non-contact state with the workpiece W stationary in the workpiece accommodating portion 110 by rotating the workpiece W integrally with the spindle 2. Moreover, the workpiece | work accommodating part 110 can accommodate the workpiece | work W stably in a stationary state.

ワークWの加工が終了すると、図3(b)に示すように、工具TがワークWから退避し、前記のように後退したワーク収容部110が、前記のようにワークWの供給を行う位置に前進し、チャック220による加工済みのワークWの把持が解除された状態で、図3(c)に示すように、押し棒130を前方に移動させ、作業位置AにワークWを供給する。図4(a)に示すように、ワークWの供給の際、作業位置Aの加工済みのワークWは供給されるワークWによって押し出されて主軸2から脱落し、図示しないワーク回収装置等によって回収され、作業位置Aに供給されたワークWがチャック220によって把持される。その後前述のようにワーク収容部110が後退した状態で、自動旋盤によるワークWの加工が可能となる。 When the processing of the workpiece W is completed, as shown in FIG. 3B, the tool T is retracted from the workpiece W, and the workpiece accommodating portion 110 that has been retracted as described above is the position where the workpiece W is supplied as described above. In the state where the gripping of the processed workpiece W by the chuck 220 is released, the push rod 130 is moved forward to supply the workpiece W to the work position A as shown in FIG. As shown in FIG. 4 (a), when the workpiece W is supplied, the processed workpiece W at the work position A is pushed out by the supplied workpiece W, falls off the main spindle 2, and is recovered by a workpiece recovery device (not shown) or the like. Then, the workpiece W supplied to the work position A is gripped by the chuck 220. Thereafter, the workpiece W can be machined by an automatic lathe in a state in which the workpiece accommodating portion 110 is retracted as described above.
