Description

本考案は、CNC旋盤加工機械の主軸及び副主軸の構造に関するものである。 The present invention relates to the structure of a spindle and a sub-spindle of a CNC lathe processing machine.

図1及び図2を参照する。図1及び図2に示すように、機械1により加工を行う際、ワークピース(workpiece)10を機械1の管クランプ11内で挟持し、キャップ(cap)12により管クランプ11を締め付けてワークピース10を固定し、軸棒を旋回させてワークピース10(図示せず)を旋回させ、ドリル(drill)13に接触させて切削作業を行う。 See FIGS. 1 and 2. As shown in FIGS. 1 and 2, when machining is performed by the machine 1, the work piece (work piece) 10 is sandwiched in the pipe clamp 11 of the machine 1, and the pipe clamp 11 is tightened by the cap (cap) 12 to tighten the workpiece. 10 is fixed, the shaft rod is swiveled to swivel the workpiece 10 (not shown), and the work piece 10 (not shown) is brought into contact with the drill 13 to perform cutting work.

しかし、図2及び図3に示すように、ワークピース10を切削して生じた切削屑100又は油泥が管クランプ11の隙間又はワークピース10内からキャップ12内に浸入し、キャップ12内に切削屑100又は油泥が一定量溜まると、ワークピース10の挟持に偏差が生じ、加工品に公差が生じて精度が下がり、加工品に不良品が生じた場合、加工品を一括で廃棄して改めて製造しなければならなくなり、メーカーにとって不都合であった。 However, as shown in FIGS. 2 and 3, the cutting chips 100 or oil mud generated by cutting the workpiece 10 infiltrate into the cap 12 from the gap of the pipe clamp 11 or the inside of the workpiece 10 and cut into the cap 12. When a certain amount of waste 100 or oil mud accumulates, a deviation occurs in the sandwiching of the workpiece 10, a tolerance occurs in the processed product, and the accuracy decreases. If a defective product occurs in the processed product, the processed product is discarded in a batch and renewed. It had to be manufactured, which was inconvenient for the manufacturer.

そのため、図3に示すように、キャップ12内に残留した切削屑100及び油泥の問題を改善するために、加工業者は、ワークピース10に生じた切削屑100の量に応じ、長年の経験に基づいてキャップ12を洗浄する時間を判断し、ワークピース10に問題が生じることを防いでいたが、キャップ12を取り出す毎に、機械の作業を一時的に止めなければならない上、手間をかけて清掃作業を行い、ワークピース10の品質をチェックしなければならず、全体の加工効率に悪影響を与えることがあった。 Therefore, as shown in FIG. 3, in order to improve the problem of the cutting chips 100 remaining in the cap 12 and the oil mud, the processor has many years of experience depending on the amount of the cutting chips 100 generated in the workpiece 10. Based on this, the time to clean the cap 12 was determined to prevent problems with the workpiece 10, but every time the cap 12 was taken out, the work of the machine had to be temporarily stopped and it took time and effort. Cleaning work had to be performed and the quality of the workpiece 10 had to be checked, which could adversely affect the overall processing efficiency.

本考案の目的は、切削屑及び油泥がキャップ内に残留することを防いで動作性能を維持する、CNC旋盤加工機械の主軸及び副主軸の構造を提供することにある。 An object of the present invention is to provide a spindle and sub-spindle structure of a CNC lathe processing machine that prevents cutting chips and oil mud from remaining in a cap and maintains operating performance.

かくして、本考案の要旨は、次の(1)に記載の通りのものである。

以下、図面により、本考案を具体的に説明する。もっとも、本考案は、かかる図面により限定されるものではない。 Hereinafter, the present invention will be specifically described with reference to the drawings. However, the present invention is not limited to such drawings.

図4を参照する。図4は、本考案の一実施形態に係るCNC旋盤加工機械の機械を示す斜視図である。図4に示すように、本考案の一実施形態に係るCNC旋盤加工機械の機械2は、少なくとも軸体21、軸管22、管クランプ23及びキャップ24にドリル25を組み合わせて構成される。軸体21は、軸棒を有し、軸管22が軸棒内に嵌入され(従来技術であるためここでは詳しく述べない)、軸管22内にはばね221が設けられ(図5を参照する)、ワークピース20を押動させると、管クランプ23が軸管22に挿入される。管クランプ23の環状縁部には、ワークピース20を挟持する溝部231が形成される。管クランプ23は、キャップ24により締め付けられる。キャップ24の外周縁には、複数の貫通孔241が形成されている。 See FIG. FIG. 4 is a perspective view showing a machine of a CNC lathe processing machine according to an embodiment of the present invention. As shown in FIG. 4, the machine 2 of the CNC lathe processing machine according to the embodiment of the present invention is configured by combining at least a shaft body 21, a shaft pipe 22, a pipe clamp 23, and a cap 24 with a drill 25. The shaft body 21 has a shaft rod, the shaft pipe 22 is fitted in the shaft rod (not described in detail here because it is a prior art), and a spring 221 is provided in the shaft pipe 22 (see FIG. 5). When the workpiece 20 is pushed, the tube clamp 23 is inserted into the shaft tube 22. A groove portion 231 for sandwiching the work piece 20 is formed at the annular edge portion of the tube clamp 23. The tube clamp 23 is tightened by the cap 24. A plurality of through holes 241 are formed on the outer peripheral edge of the cap 24.

実際に組立てる際、図5及び図6に示すように、管クランプ23を軸管22内に挿入するとき、ワークピース20を管クランプ23内に挿入し(図8を参照する)、キャップ24に管クランプ23を挿通させて軸管22に締め付け、ワークピース20を軸管22内で挟持する。 During actual assembly, as shown in FIGS. 5 and 6, when the tube clamp 23 is inserted into the shaft tube 22, the workpiece 20 is inserted into the tube clamp 23 (see FIG. 8) and into the cap 24. The tube clamp 23 is inserted and tightened to the shaft tube 22, and the workpiece 20 is sandwiched in the shaft tube 22.

図7を参照する。図7に示すように、キャップ24の外周縁の貫通孔241は、好ましくは放射線状に配置された傾斜孔2410である。キャップ24内の切削屑200及び油泥は、傾斜孔2410を介して遠心力がかかる方向で内から外方へ向かって振り飛ばされる(図8を参照する)。 See FIG. 7. As shown in FIG. 7, the through hole 241 on the outer peripheral edge of the cap 24 is preferably an inclined hole 2410 arranged radially. The cutting chips 200 and oil mud in the cap 24 are shaken from the inside to the outside in the direction in which centrifugal force is applied through the inclined holes 2410 (see FIG. 8).

実際に加工を行うときは、図8及び図9に示すように、まず、ワークピース20を管クランプ23内に挿設させ、キャップ24によりワークピース20を締め付け、管クランプ23によりワークピース20を挟持して切削作業を行う。続いて、軸体21を旋回させて軸管22を旋回させると、管クランプ23が一緒に旋回してワークピース20が旋回する。また、ワークピース20に接触されるドリル25の角度を調整すると、必要な寸法及び形状に切削することができる。ワークピース20を切削すると、切削屑200及び油泥が生じる。管クランプ23が旋回すると、切削屑200及び油泥が管クランプ23の隙間又はワークピース20内からキャップ24内に滑り落ち、軸体21の旋回により発生した遠心力によりキャップ24内に溜まった切削屑200及び油泥が傾斜孔2410を介して振り飛ばされるため、キャップ24内に切削屑200及び油泥が残留することを防ぎ、切削屑200及び油泥により管クランプ23の挟持力に悪影響を与えることを防ぐこともできる。そのため、ワークピース20の切削精度が高まり、ワークピース20の収率が大幅に向上する。 When actually processing, as shown in FIGS. 8 and 9, first, the workpiece 20 is inserted into the tube clamp 23, the workpiece 20 is tightened by the cap 24, and the workpiece 20 is fastened by the tube clamp 23. Clamp and perform cutting work. Subsequently, when the shaft body 21 is swiveled to swivel the shaft pipe 22, the pipe clamp 23 is swiveled together and the workpiece 20 is swiveled. Further, by adjusting the angle of the drill 25 in contact with the work piece 20, it is possible to cut into a required size and shape. Cutting the workpiece 20 produces cutting chips 200 and oil mud. When the pipe clamp 23 turns, the cutting chips 200 and oil mud slide down into the cap 24 from the gap of the pipe clamp 23 or the work piece 20, and the cutting chips accumulated in the cap 24 due to the centrifugal force generated by the turning of the shaft body 21. Since the 200 and the oil mud are shaken off through the inclined hole 2410, the cutting chips 200 and the oil mud are prevented from remaining in the cap 24, and the cutting chips 200 and the oil mud are prevented from adversely affecting the holding force of the pipe clamp 23. You can also do it. Therefore, the cutting accuracy of the workpiece 20 is improved, and the yield of the workpiece 20 is significantly improved.

上述したことから分かるように、本考案のCNC旋盤加工機械の主軸及び副主軸の構造は、その全体構成を変更せず、キャップの外周縁に複数の貫通孔を形成し、軸体の旋回により生じた遠心力により、キャップ内の切削屑及び油泥を振り飛ばし、切削屑及び油泥がキャップ内に残留していた問題を改善することができる。本考案は、改良点が簡素であるが、実際の加工作業では大きな助けとなり、装置の清掃時間を減らすことができる上、完成品の収率を高めることもできる。 As can be seen from the above, the structure of the spindle and the sub-spindle of the CNC lathe processing machine of the present invention does not change the overall configuration, but a plurality of through holes are formed on the outer peripheral edge of the cap, and the shaft body is swiveled. The generated centrifugal force can shake off the cutting chips and oil mud in the cap, and can improve the problem that the cutting chips and oil mud remain in the cap. Although the improvement of the present invention is simple, it is a great help in the actual processing work, the cleaning time of the device can be reduced, and the yield of the finished product can be increased.
