Description

本発明は被切削物を切削するための切削装置に関する。   The present invention relates to a cutting device for cutting a workpiece.

切削装置は工作機械に取着され、例えば工作機械の回転動力により回転し、被切削物を切削する。被切削物を平面的に切削する切削装置は、円形外周部の複数の周方向位置に刃体取付面を有し、円筒形をなす刃体保持具と、前切刃及び横切刃を有し前記刃体取付面の夫々にボルトにより着脱可能に取付けられる刃体とを備える(例えば、非特許文献1参照)。このように構成された切削装置は、刃体の夫々の刃先位置が決められた状態で刃体の夫々が固定されている。この位置決めは、刃体保持具の径方向位置及び回転中心方向位置が決められている。

The cutting device is attached to the machine tool, and is rotated by, for example, the rotational power of the machine tool to cut the workpiece. A cutting device for cutting a workpiece in a planar manner has a blade mounting surface at a plurality of circumferential positions on a circular outer peripheral portion, and has a cylindrical blade holder, a front cutting blade and a side cutting blade. And a blade body that is detachably attached to each of the blade body attachment surfaces by a bolt (see Non-Patent Document 1, for example). In the cutting apparatus configured as described above, each of the blade bodies is fixed in a state where the position of each blade edge of the blade body is determined. In this positioning, the radial position and the rotational center direction position of the blade holder are determined.
Moreover, when cutting a to-be-cut object, each blade body cuts in order with rotation of a cutting device.

ところで、非特許文献1のように構成された切削装置が被切削物を切削する場合、切削装置の回転にともない各刃体が順に切削を行うが、刃体の刃先の摩耗量は夫々の刃体により異なるため、例えば一つの刃体の前切刃及び横切刃の摩耗量が他の刃体の前切刃及び横切刃の摩耗量に比べて多く、削れなくなったとき、削れる刃体数が減少し、この減少した刃体数の刃体により切削されるため、一回転当たりの切削効率が悪くなり、許容される単位時間内に切削することができなくなる。   By the way, when the cutting device configured as in Non-Patent Document 1 cuts an object to be cut, each blade body sequentially cuts along with the rotation of the cutting device. For example, the amount of wear on the front and side cutting blades of one blade is larger than the amount of wear on the front and side cutting blades of other blades, and the blade can be cut when it cannot be cut. Since the number is reduced and cutting is performed by the blades having the reduced number of blades, the cutting efficiency per one rotation is deteriorated and the cutting cannot be performed within an allowable unit time.

ところが、従来の切削装置は、刃体の、刃体保持具の径方向位置及び回転中心方向位置を調整することができないように構成されているため、許容される単位時間内に切削することができなくなったとき、切削装置を工作機械から取外し、全ての刃体を研磨して夫々の刃先の、刃体保持具の径方向位置及び回転中心方向位置が等しくなるように補修する必要があり、この補修作業に時間と労力とを必要とし、また、補修期間中は切削作業を行うことができず、代替用の新たな切削装置が必要であり、改善策が要望されていた。   However, since the conventional cutting device is configured so that the radial position and the rotation center direction position of the blade holder cannot be adjusted, the cutting can be performed within an allowable unit time. When it is no longer possible, it is necessary to remove the cutting device from the machine tool, grind all the blade bodies, and repair each blade edge so that the radial position and the rotation center direction position of the blade holder are equal. This repair work requires time and labor. Further, the cutting work cannot be performed during the repair period, and a new cutting device for replacement is necessary, and an improvement measure has been demanded.

本発明は斯かる事情に鑑みてなされたものであり、主たる目的は刃体を刃体保持具の回転中心方向へ移動可能とし、該刃体及び刃体取付面の一方に傾斜面を設け、該傾斜面に接触する傾斜面を有し、且つ刃体及び刃体取付面の間に回転中心の方向へ移動可能に調整体を配置することにより刃体の、刃体保持具の径方向位置及び回転中心方向位置を調整することができる切削装置を提供することにある。   The present invention has been made in view of such circumstances, the main purpose is to be able to move the blade body toward the center of rotation of the blade body holder, provided an inclined surface on one of the blade body and the blade body mounting surface, A radial position of the blade body holder of the blade body by disposing an adjustment body that has an inclined surface that contacts the inclined surface and is movable in the direction of the rotation center between the blade body and the blade body mounting surface. And it is providing the cutting device which can adjust a rotation center direction position.

また、他の目的は刃体及び調整体を回転中心の方向へ個別に移動させる第1及び第2の操作体を刃体保持具に設けることにより、刃体の径方向位置及び回転中心方向位置を簡易に且つ正確に調整することができる切削装置を提供することにある。   Another object is to provide the blade body holder with first and second operating bodies that individually move the blade body and the adjustment body in the direction of the rotation center, thereby providing a radial position and a rotation center direction position of the blade body. It is providing the cutting device which can adjust easily and correctly.

また、他の目的は刃体取付面に臨む凸壁を設け、該凸壁及び刃体取付面の夫々に螺子孔を設け、これら螺子孔に螺着するボルトにより調整体及び刃体の位置調整と、刃体の固定とを行うことができる切削装置を提供することにある。   Another object is to provide a convex wall facing the blade body mounting surface, provide screw holes in each of the convex wall and the blade body mounting surface, and adjust the position of the adjusting body and the blade body by bolts screwed into these screw holes. Another object of the present invention is to provide a cutting apparatus capable of fixing the blade body.

第1発明に係る切削装置は、円形外周部の複数の周方向位置に刃体取付面を有し、且つ工作機械に回転を可能に取着される刃体保持具と、前記刃体取付面に着脱可能に取付けられる刃体とを備える切削装置において、前記刃体は前記刃体保持具の回転中心の方向へ移動が可能であり、該刃体及び前記刃体取付面の一方は第1の傾斜面を有しており、該第1の傾斜面に接触する第2の傾斜面を有し、且つ前記刃体及び刃体取付面の間に前記回転中心の方向へ移動可能に配置され前記刃体の位置を調整する調整体を備え、該調整体及び前記刃体を固定する固定具を備えることを特徴とする。   A cutting device according to a first aspect of the present invention includes a blade holder that has a blade attachment surface at a plurality of circumferential positions on a circular outer peripheral portion and is rotatably attached to a machine tool, and the blade attachment surface.

Thereafter, the adjustment state can be maintained by operating the fixing bolt.

第1発明によれば、許容される単位時間内に切削することができなくなったときにおいても、削れなくなった刃体に対応する操作体を操作することにより、削れなくなった刃体だけの、刃体保持具の径方向位置及び回転中心方向位置を調整することができ、補修作業に必要な時間及び労力を軽減でき、補修費用を低減できるとともに、補修期間を短縮できる。   According to the first invention, even when it becomes impossible to cut within the permissible unit time, by operating the operating body corresponding to the blade that can no longer be cut, only the blade that can no longer be cut can be obtained. The radial position and the rotation center direction position of the body holder can be adjusted, time and labor required for repair work can be reduced, repair costs can be reduced, and the repair period can be shortened.

第2発明によれば、第1及び第2の操作体を操作することにより刃体の、刃体保持具の径方向位置及び回転中心方向位置を簡易に且つ正確に調整することができる。   According to the second invention, the radial position and the rotational center direction position of the blade holder can be easily and accurately adjusted by operating the first and second operating bodies.

Further, the adjusting body 3 passes through the second inclined surface 31 and corresponds to the first screw hole 14, and extends from one end in the longitudinal direction to one of the long holes 32, and the second screw. A fourth screw hole 33 corresponding to the hole 15 is provided.

以上のように構成された切削装置は、刃体保持具1の刃体取付面11に調整体3が載置され、該調整体3に刃体2が載置され、第1及び第2の傾斜面21,31が接触している。この状態で刃体2の長孔22,22から調整体3の長孔32,32に固定具としての第3のボルト6,6が挿通され、該ボルト6,6が第1の螺子孔14,14に螺着される。また、第2及び第4の螺子孔15,33に操作体としての第1のボルト4が螺着され、さらに第3の螺子孔16に操作体としての第2のボルト5が螺着され、該ボルト5の先端が刃体2の端面に当接している。   In the cutting apparatus configured as described above, the adjustment body 3 is placed on the blade body mounting surface 11 of the blade body holder 1, the blade body 2 is placed on the adjustment body 3, and the first and second The inclined surfaces 21 and 31 are in contact. In this state, third bolts 6, 6 as fixtures are inserted from the long holes 22, 22 of the blade body 2 into the long holes 32, 32 of the adjustment body 3, and the bolts 6, 6 are inserted into the first screw holes 14. , 14. In addition, the first bolt 4 as the operating body is screwed into the second and fourth screw holes 15 and 33, and the second bolt 5 as the operating body is screwed into the third screw hole 16, The tip of the bolt 5 is in contact with the end surface of the blade body 2.

第2及び第4の螺子孔15,33に螺着された第1のボルト4を一方向に回すと、調整体3が回転中心Oの一方へ移動し、刃体2を刃体保持具1の径方向Xの外側(図3の下方)へ位置調整することができる。また、第3の螺子孔16に螺着された第2のボルト5を一方向に回すと、刃体2が回転中心Oの一方(図3の左方)へ移動し、回転中心方向位置を調整することができる。尚、凸壁12と刃体2及び調整体3との間に隙間を発生させている場合は、第1のボルト4を他方向に回すと、調整体3を回転中心Oの他方へ移動させ、刃体2を径方向Xの内側へ位置調整することができ、また、第2のボルト5を他方向に回すと、第2のボルト5の先端及び刃体2間に隙間が発生し、該隙間の範囲で刃体2を回転中心方向の他方へ移動させ、回転中心方向位置を調整することができる。   When the first bolt 4 screwed into the second and fourth screw holes 15 and 33 is turned in one direction, the adjusting body 3 moves to one of the rotation centers O, and the blade body 2 is moved to the blade body holder 1. The position can be adjusted to the outside in the radial direction X (downward in FIG. 3). When the second bolt 5 screwed into the third screw hole 16 is turned in one direction, the blade body 2 moves to one of the rotation centers O (leftward in FIG. 3), and the position in the rotation center direction is set. Can be adjusted. When a gap is generated between the convex wall 12 and the blade body 2 and the adjustment body 3, turning the first bolt 4 in the other direction causes the adjustment body 3 to move to the other of the rotation centers O. The blade body 2 can be adjusted in position in the radial direction X, and when the second bolt 5 is turned in the other direction, a gap is generated between the tip of the second bolt 5 and the blade body 2, The blade body 2 can be moved to the other direction of the rotation center within the range of the gap, and the position of the rotation center direction can be adjusted.

従って、例えば一つの刃体2が削れなくなり、一回転当たりの切削効率が悪くなり、許容される単位時間内に切削することができなくなったとき、この一つの刃体2に対応する第1及び第2のボルト4,5を回し操作することにより、削れなくなっている刃体2の、刃体保持具1の回転中心方向位置、及び径方向位置を簡易に、且つ正確に調整することができ、補修作業に必要な時間及び労力を軽減でき、補修費用を低減できるとともに、補修期間を短縮できる。   Therefore, for example, when one blade body 2 cannot be cut, the cutting efficiency per one rotation is deteriorated, and cutting cannot be performed within an allowable unit time, the first and second blades 2 corresponding to the one blade body 2 are cut. By turning and operating the second bolts 4 and 5, the rotational center direction position and the radial direction position of the blade body holder 1 of the blade body 2 that cannot be shaved can be easily and accurately adjusted. The time and labor required for the repair work can be reduced, the repair cost can be reduced, and the repair period can be shortened.

尚、工作機械への取着は、刃体保持具1の貫通孔1aに工作機械の回転軸が嵌入され、該回転軸の先端にボルトを螺着することにより実行することができる。   The attachment to the machine tool can be performed by inserting the rotating shaft of the machine tool into the through hole 1a of the blade holder 1 and screwing a bolt to the tip of the rotating shaft.
