この考案の一実施例を図１および図２に基づき説明する。 図１は、この実施例のワーク仮置装置２を装備した旋盤１の要部を示す正面図 である。旋盤１のベッド３上には主軸４と心押台５とが対向して配置されており 、主軸４にはワークＷの一端を把持するチャック６が設けられている。心押台５ には、ワークＷの他端の中心を押圧する心押軸７が上記チャック６に向けて進退 自在に設けられ、内蔵の油圧シリンダによって進退駆動される。 An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view showing a main part of a lathe 1 equipped with a work temporary placement device 2 of this embodiment. A spindle 4 and a tailstock 5 are arranged on the bed 3 of the lathe 1 so as to face each other, and the spindle 4 is provided with a chuck 6 for gripping one end of the work W. A tailstock shaft 7 for pressing the center of the other end of the work W is provided on the tailstock 5 so as to be movable back and forth toward the chuck 6, and is driven forward and backward by a built-in hydraulic cylinder.
【０００８】 心押台５には、ワーク仮置装置２を構成するワーク仮置台８が揺動自在に設け られている。このワーク仮置台８は、主軸４と心押軸７との間にワークＷを配置 するための台であって、チャック６と心押軸７の間に配置した台本体９から心押 台５側に延びるアーム10の基端部が支軸11によって心押台５に揺動自在に支持さ れている。すなわち、台本体９がチャック６と心押軸７の間から回動して下側に 退避できる。台本体９の上面には、上端にワーク載架用Ｖ字溝を有する複数の支 持ブロック12が突設されている。The tailstock 5 is provided with a work temporary placement table 8 that constitutes the work temporary placement device 2 so as to be swingable. The work temporary placing table 8 is a table for arranging the work W between the spindle 4 and the tailstock shaft 7, and includes a base body 9 arranged between the chuck 6 and the tailstock shaft 7 to the tailstock 5. A base end portion of an arm 10 extending toward the side is swingably supported by a tailstock 5 by a support shaft 11. That is, the base body 9 can be rotated from between the chuck 6 and the tailstock shaft 7 and retracted downward. On the upper surface of the table body 9, a plurality of support blocks 12 having a V-shaped groove for mounting a work on the upper end are provided in a protruding manner.
【０００９】 また、心押台５には、ワーク仮置台８を上昇付勢する復帰ばね13が設けられ、 下降操作用のカム15の下面に押当てることにより、その台本体９を主軸４に対応 する高さに規制している。Further, the tailstock 5 is provided with a return spring 13 for urging the work temporary placing table 8 upward, and by pushing it against the lower surface of the cam 15 for lowering operation, the table main body 9 is attached to the spindle 4. It is regulated to the corresponding height.
【００１０】 カム15は心押軸７に設けられ、ワーク仮置台８のアーム10には、心押軸７の前 進に伴って上記カム15に係合しワーク仮置台８を下降させるカムフォロワ16が設 けられている。また、心押台５の本体部には、ワーク仮置台８の台本体９上に落 下堆積する切粉を排除するエアノズル17が台本体９上に向けて配置されている。The cam 15 is provided on the tailstock shaft 7, and the arm 10 of the workpiece temporary placing base 8 is provided with a cam follower 16 that engages with the cam 15 as the tailstock shaft 7 moves forward and lowers the workpiece temporary placing base 8. Is set up. In addition, an air nozzle 17 that removes chips that fall and accumulate on the table body 9 of the workpiece temporary placement table 8 is arranged on the table body 9 in the body part of the tailstock 5.
【００１１】 上記構成の動作を図２を参照して、以下に説明する。図１に示すように、心押 台５の心押軸７が後退位置にある状態で、心押軸７のカム15とワーク仮置台８側 のカムフォロワ16とは係合解除の状態にあり、ワーク仮置台８はその台本体９が 主軸４のチャック６に対応する高さとなる位置まで復帰ばね13によって上昇付勢 されている。The operation of the above configuration will be described below with reference to FIG. As shown in FIG. 1, when the tailstock shaft 7 of the tailstock 5 is in the retracted position, the cam 15 of the tailstock shaft 7 and the cam follower 16 on the workpiece temporary placement base 8 side are in the disengaged state, The workpiece temporary placing table 8 is biased upward by a return spring 13 to a position where the table body 9 has a height corresponding to the chuck 6 of the spindle 4.
【００１２】 この状態のもとで、図示しないワーク供給装置によりワーク仮置台８の支持ブ ロック12上にワークＷが載架される。次に、心押台５の心押軸７が、内蔵のシリ ンダの駆動により図２（Ａ）に示すように主軸４のチャック６に向けて前進する と、これに伴って心押軸７と一体のカム15がワーク仮置台８側のカムフォロワ16 に近づく。In this state, the work W is placed on the support block 12 of the work temporary placement table 8 by a work supply device (not shown). Next, when the tailstock shaft 7 of the tailstock 5 advances toward the chuck 6 of the main shaft 4 as shown in FIG. 2 (A) by the drive of the built-in cylinder, the tailstock shaft 7 is accompanied by this. The cam 15, which is integrated with, approaches the cam follower 16 on the side of the workpiece temporary placing table 8.
【００１３】 前進する心押軸７に押されるワークＷの一端が装着予定位置まで主軸４のチャ ック６に挿入されると心押軸７の前進は停止させられ、ワークＷの一端がチャッ ク６に把持される一方、ワークＷの他端が心押軸７に押圧される。このとき、心 押軸７と一体のカム15は、図２（Ｂ）に示すようにワーク仮置台８側のカムフォ ロワ16に係合する。その結果、ワーク仮置台８は復帰ばね13の上昇付勢力に抗し て下側に回動し、台本体９がワーク支持位置からワークＷの加工の妨げにならな い位置まで退避する。When one end of the work W pushed by the moving tailstock shaft 7 is inserted into the chuck 6 of the main shaft 4 up to the expected mounting position, the movement of the tailstock shaft 7 is stopped and one end of the work W is chucked. The other end of the work W is pressed by the tailstock shaft 7 while being gripped by the hook 6. At this time, the cam 15 integrated with the tailstock shaft 7 engages with the cam follower 16 on the workpiece temporary placing table 8 side, as shown in FIG. 2 (B). As a result, the workpiece temporary placing table 8 rotates downward against the upward biasing force of the return spring 13, and the table body 9 retracts from the workpiece supporting position to a position where it does not hinder the machining of the workpiece W.
【００１４】 主軸４のチャック６と心押軸７とで支持されたワークＷは、この状態で加工さ れる。加工が完了すると、心押軸７は元の位置まで後退してワークＷに対する押 圧が解除される。これに伴って、カム15とカムフォロワ16との係合が解かれ、ワ ーク仮置台８はワークＷを支持する高さ位置まで上昇復帰する。ついで、加工済 みワークＷは図示しないワーク供給装置により旋盤１から排出される。The work W supported by the chuck 6 of the main shaft 4 and the tailstock shaft 7 is processed in this state. When the machining is completed, the tailstock shaft 7 retracts to the original position and the pressing force on the work W is released. Along with this, the engagement between the cam 15 and the cam follower 16 is released, and the work temporary placing table 8 is returned to the height position for supporting the work W. Next, the processed work W is discharged from the lathe 1 by a work supply device (not shown).
【００１５】 加工によりワーク仮置台８の台本体９上に落下堆積する切粉は、適宜、エアノ ズル17から吹き付けられるエアによって排除される。その結果、台本体９の支持 ブロック12上には、切粉などに妨げられることなく常に適正にワークＷが載架さ れる。The chips that fall and accumulate on the table body 9 of the workpiece temporary placement table 8 during processing are appropriately removed by the air blown from the air nozzle 17. As a result, the work W is always properly mounted on the support block 12 of the base body 9 without being obstructed by chips and the like.
【００１６】 なお、上記実施例では、復帰ばね13を復帰用部材としてワーク仮置台８を上昇 付勢する構成について示したが、この他に復帰用部材として、バランスウエイト や空気圧ばねを用いてもよい。 また、上記実施例では、ワーク仮置台８を支軸11を支点にして下側に揺動退避 できるように構成したが、ワーク仮置台８を垂直に昇降させる構成としてもよい 。In the above embodiment, the return spring 13 is used as the return member to urge the work temporary placement table 8 to rise, but in addition to this, a balance weight or a pneumatic spring may be used as the return member. Good. Further, in the above-described embodiment, the work temporary placement table 8 is configured to be swingable and retractable downward with the support shaft 11 as a fulcrum, but the work temporary placement table 8 may be vertically moved up and down.
