Description

この発明は、主軸台および心押台にワークを脱着する際に、ワークを仮受するワーク仮受装置に関する。   The present invention relates to a workpiece temporary receiving device that temporarily receives a workpiece when the workpiece is attached to or detached from a spindle stock and a tailstock.

この種の装置としては、定位置に位置させられている主軸台と、主軸台に対し接近・離隔する方向に移動自在である心押台とを備えている工作機械において、ワークがまたがって載置される第１仮受台および第２仮受台を備えており、第１仮受台は、主軸台に固定されており、第２仮受台は、心押台に固定されているものが知られている（例えば、特許文献１、特許文献２参照。）。   This type of device is a machine tool equipped with a headstock positioned at a fixed position and a tailstock that is movable in a direction approaching and separating from the headstock. A first temporary holder and a second temporary holder, the first temporary holder being fixed to the headstock, and the second temporary holder being fixed to the tailstock Is known (see, for example, Patent Document 1 and Patent Document 2).

上記装置では、主軸台および心押台にワークを脱着するに際し、ワークの大きさに対応して心押台が移動させられ、心押台とともに第２仮受台が移動させられる。そのため、ワークが第２仮受台と擦れ合って、ワークに傷を付けてしまうことがある。さらに、ワークに外径の異なる段が付いていると、ワークと第２仮受台が引っ掛かって衝突してしまう等の問題点があった。
特開平５−１６００３号公報 実用新案登録第２５２８７４４号公報 In the above apparatus, when the workpiece is attached to or detached from the spindle stock and the tailstock, the tailstock is moved in accordance with the size of the workpiece, and the second temporary support is moved together with the tailstock. For this reason, the work may be rubbed against the second temporary holder and the work may be damaged. Further, when the workpiece has steps with different outer diameters, there has been a problem that the workpiece and the second provisional stand are caught and collide.
Japanese Patent Laid-Open No. 5-16003 Utility Model Registration No. 2528744

この発明の目的は、ワークに傷付ける心配の無いワーク仮受装置を提供することにある。   An object of the present invention is to provide a workpiece provisional receiving device that does not cause damage to the workpiece.

この発明によるワーク仮受装置は、定位置に位置させられている主軸台と、主軸台に対し接近・離隔する方向に移動自在である心押台とを備えている工作機械において、ワークがまたがって載置される第１仮受台および第２仮受台を備えており、第１仮受台は、機械フレームまたは主軸台に固定されており、心押台に、これを長さ方向に移動自在に支持ロッドが支持されており、支持ロッドは、心押台から主軸台側に突出させられた支持部を有しており、支持部に、第２仮受台が固定されており、支持ロッドを長さ方向に位置調節自在に規制するストッパを備えているものである。   A workpiece temporary receiving device according to the present invention is a machine tool including a headstock positioned at a fixed position and a tailstock that is movable in a direction approaching and separating from the headstock. The first temporary holder and the second temporary holder, which are fixed to the machine frame or the spindle stock, are placed on the tailstock in the length direction. A support rod is supported movably, the support rod has a support portion that protrudes from the tailstock toward the headstock, and the second temporary support is fixed to the support portion. A stopper that restricts the position of the support rod in the length direction is provided.

この発明によるワーク仮受装置では、ワークの脱着に際し、心押台を移動させても、支持ロッドはストッパによって移動を規制されるため、支持ロッドとともに第２仮受台は定位置に留められる。したがつて、ワークが第２仮受台と擦れ合ったりして傷付けられる恐れが無い。   In the workpiece temporary receiving apparatus according to the present invention, even when the tailstock is moved when the workpiece is attached or detached, the movement of the support rod is restricted by the stopper, so that the second temporary holding table is held at a fixed position together with the support rod. Therefore, there is no fear that the work is rubbed against the second temporary holder and damaged.

この発明によれば、ワークに傷付ける心配の無いワーク仮受装置が提供される。   According to the present invention, there is provided a workpiece provisional device that does not cause any damage to the workpiece.

この発明の実施の形態を図面を参照しながらつぎに説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１および図２を参照すると、主軸台11および心押台12が相対するにように配備されている。主軸台11および心押台12は、ともに、Ｚ軸方向（図１および図２の左右方向）にのびた軸線を有している。   1 and 2, the headstock 11 and the tailstock 12 are arranged so as to face each other. Both the headstock 11 and the tailstock 12 have an axis extending in the Z-axis direction (the left-right direction in FIGS. 1 and 2).

主軸台11は、定位置に位置させられている。心押台12は、Ｚ軸方向に互いに平行にのびた一対の水平ガイドレール21にまたがって移動自在に支持されている（図３）。両ガイドレール21の間には、これと平行にのびたねじ棒22が設けられている。ねじ棒22には、心押台12と一体化された雌ねじ体23がねじ合わされている。ねじ棒22の一端部にはモータ24の出力軸が連結されている。   The head stock 11 is positioned at a fixed position. The tailstock 12 is supported movably across a pair of horizontal guide rails 21 extending parallel to each other in the Z-axis direction (FIG. 3). Between the two guide rails 21, a threaded rod 22 extending in parallel therewith is provided. A female screw body 23 integrated with the tailstock 12 is screwed onto the screw rod 22. The output shaft of the motor 24 is connected to one end of the screw rod 22.

モータ24の駆動により、ねじ棒22が正逆回転されられ、これにより、雌ねじ体23とともに心押台12が主軸台11に対し接近・離隔させられる。   By driving the motor 24, the screw rod 22 is rotated forward and backward, whereby the tailstock 12 together with the internal thread body 23 is moved toward and away from the headstock 11.

主軸台11の、心押台12と相対する面には、水平固定バー31が心押台12に向かって突出させられている。固定バー31には可動バー32がＺ軸方向に移動自在に支持されている。可動バー32には、Ｚ軸方向にのびた水平長孔33が形成されている。長孔33を通して調整ねじ34が固定バー31にねじ込まれている。可動バー32には第１仮受台35が固定されている。   A horizontal fixing bar 31 is protruded toward the tailstock 12 on the surface of the headstock 11 facing the tailstock 12. A movable bar 32 is supported on the fixed bar 31 so as to be movable in the Z-axis direction. The movable bar 32 is formed with a horizontal long hole 33 extending in the Z-axis direction. An adjusting screw 34 is screwed into the fixing bar 31 through the long hole 33. A first temporary holder 35 is fixed to the movable bar 32.

心押台12の高さの中程には、Ｚ軸方向に互いに平行にのびた一対の水平長ガイド孔41が形成されている。各長ガイド孔41には支持ロッド42が貫通させられている。支持ロッド42外面および長ガイド孔41周面間にはブッシュ43が介在させられている。各支持ロッド42は、対応する長ガイド孔41から主軸台11側に突出させられた支持部44を有している。両支持ロッド42の支持部44には第２仮受台45がまたがって支持ロッド42の長さ方向に摺動自在に支持されている。第２仮受台45には止めねじ46がねじ込まれている。   In the middle of the height of the tailstock 12, a pair of horizontally long guide holes 41 extending in parallel with each other in the Z-axis direction is formed. A support rod 42 is passed through each long guide hole 41. A bush 43 is interposed between the outer surface of the support rod 42 and the peripheral surface of the long guide hole 41. Each support rod 42 has a support portion 44 that protrudes from the corresponding long guide hole 41 to the headstock 11 side. A second temporary support 45 is supported by the support portions 44 of both support rods 42 so as to be slidable in the length direction of the support rods 42. A set screw 46 is screwed into the second temporary holder 45.

止めねじ46の先端部を支持部44外面に押圧させるように止めねじ46をねじ込むことによって、支持部44に第２仮受台45が固定され、この状態から、止めねじ46を第２仮受台45から抜け出るように緩めることによって、支持部44に対し第２仮受台45が移動自在となる。   By screwing the set screw 46 so that the tip of the set screw 46 is pressed against the outer surface of the support portion 44, the second temporary support base 45 is fixed to the support portion 44. From this state, the set screw 46 is received by the second temporary support. By loosening the base 45 so as to come out, the second temporary support 45 can be moved with respect to the support portion 44.

心押台12を挟んで支持ロッド42の支持部44と反対側の端部にストッパ51が備えられている。ストッパ51は、機械フレーム52から立ち上がっている垂直スタンド状のものである。ストッパ51の上端部には両支持ロッド42を摺動自在に貫通させた水平短ガイド孔53が形成されている。短ガイド孔53の周囲に止めねじ54がねじ込まれている。   A stopper 51 is provided at the end of the support rod 42 opposite to the support portion 44 with the tailstock 12 interposed therebetween. The stopper 51 has a vertical stand shape that rises from the machine frame 52. At the upper end of the stopper 51, a horizontal short guide hole 53 is formed through which both support rods 42 are slidably penetrated. A set screw 54 is screwed around the short guide hole 53.

止めねじ54をねじ込んでその先端部で支持ロッド42の外面を押圧すると、支持ロッド42の長さ方向の移動が規制され、止めねじ54を緩めると、支持ロッド42の長さ方向の移動が自由となる。   When the set screw 54 is screwed in and the outer surface of the support rod 42 is pressed at the tip, the movement of the support rod 42 in the length direction is restricted, and when the set screw 54 is loosened, the support rod 42 is free to move in the length direction. It becomes.

第１仮受台35および第２仮受台45にまたがって丸棒状ワークＷが載置されている。ワークＷの長さに対応して、第２仮受台45を移動させることによって第１仮受台35および第２仮受台45の間隔が調整される。ワークＷの載置に際しては、心押台12は、ワークＷから遠ざけられている。第１仮受台35および第２仮受台45にワークＷが載置されると、心押台12を主軸台11に対し接近させる方向に移動させて、主軸台11および心押台12によってワークＷを保持し、この状態で、ワークＷの加工が行われる。   A round bar-shaped workpiece W is placed across the first temporary support base 35 and the second temporary support base 45. The distance between the first temporary holder 35 and the second temporary holder 45 is adjusted by moving the second temporary holder 45 in accordance with the length of the workpiece W. When placing the workpiece W, the tailstock 12 is kept away from the workpiece W. When the workpiece W is placed on the first temporary holder 35 and the second temporary holder 45, the tailstock 12 is moved in a direction to approach the spindle stock 11, and the spindle stock 11 and the tailstock 12 The workpiece W is held, and the workpiece W is processed in this state.
