Description
本発明は、ＣＮＣ旋盤の技術分野に関し、具体的には、ＣＮＣ旋盤のバイトの同時多重操作機構であり、これにより同一時点に複数のバイトを使用することができ、効果的に加工精度を高め、加工時間およびバイトの不足を減少させる。 TECHNICAL FIELD The present invention relates to the technical field of CNC lathes, and more specifically, to a simultaneous multiple operation mechanism for CNC lathe tools, which allows multiple tools to be used at the same time, effectively increasing machining accuracy. , to reduce machining time and lack of tools.
近年、ＣＮＣ旋盤産業は急速に発展している。コンピュータ制御を用いる旋盤機器は、モータおよびその関連する対応部品を必要とする。モータは一定の体積を有し、現在の技術では克服することができないため、ＣＮＣ旋盤を設計するとき、このことに制限される。加工するとき、同一時間に使用することができるバイトの数および加工速度は従来のカム式機器より遅い。しかし、従来のカム式機器自体は、カムによって各機構および刃物台を動かすため、加工するとき、経験のある作業者が本体を操作する必要がある。また該機器は成形バイトを必要とし、ＣＮＣ旋盤が市販の使い捨てバイトを使用して、簡単に操作することができるのとは異なる。該機器は加工精度が安定せず、精確にバイトの摩耗補正をすることができない。これは両者の矛盾する点である。 In recent years, the CNC lathe industry has developed rapidly. Lathe machines that use computer control require motors and their associated counterparts. This limits us when designing a CNC lathe because the motor has a fixed volume which cannot be overcome with current technology. When machining, the number of bites that can be used at the same time and the machining speed are slower than conventional cam-type machines. However, the conventional cam-type equipment itself requires an experienced operator to operate the main body during processing because each mechanism and tool post are moved by the cam. Also, the instrument requires a shaped bit, unlike a CNC lathe, which uses a commercially available disposable bit and can be easily operated. The machine does not have stable machining accuracy and cannot accurately compensate for wear of the cutting tool. This is a point of contradiction between the two.
さらに、くし刃型刃物台のＣＮＣ旋盤は、加工のたびに、くし刃型刃物台上に複数のバイトを装着することができる。しかし、加工するとき、複数のバイトで同一時点に加工することができず、各バイトは相互に待つ必要がある。従来のカム式機器は機器の主軸上方に３つの刃物台を有し、各刃物台は１つのバイトを有する。各刃物台は上下に移動することしかできず、各刃物台は相互に待つ必要がある。このほか、該機器の主軸前方に２つのバイトを有する刃物台を１つ有するが、この刃物台は前進、後退して、内孔を開ける動作を行うことしかできない。この機器のすべての作動はカムによるため、機器のバイト調整は経験を有する作業者による指導が必要である。 Furthermore, the gang tool post CNC lathe can mount a plurality of tools on the gang tool post each time machining is performed. However, when processing, multiple bytes cannot be processed at the same time, and each byte must wait for each other. A conventional cam-type instrument has three turrets above the spindle of the instrument, each turret having one bit. Each turret can only move up and down, each turret must wait for each other. In addition, there is one tool rest with two cutting tools in front of the main shaft of the machine, but this tool rest can only move forward and backward to open a bore. Since all actuation of this device is cam driven, tool bite adjustment must be supervised by an experienced operator.
前記問題を解決するため、発明者は以前に中華民国実用新案出願番号第１０２２１８１２１号の「ＣＮＣ旋盤の複数バイトの同時機構」を開発している。これは、複数バイトが同時に異なる寸法の外径加工を行うことができ、主軸方向の内径加工を行うこともできる。これにより、同一時点に少なくとも２つのバイトを使用することができ、バイトの数が増加するだけでなく、加工時間を短縮することができる。それ以外にも、バイトを交換する時間を節約することができ、実用性が向上する。しかし、本発明者はこれに満足せず、効率および実用性をさらに向上させるために、積極的に開発を行っている。 In order to solve the above problems, the inventor has previously developed a "simultaneous mechanism for multiple bites of a CNC lathe" of ROC Utility Model Application No. 102218121 . This allows a plurality of cutting tools to simultaneously perform outer diameter machining of different dimensions, and can also perform inner diameter machining in the direction of the spindle. This allows at least two bits to be used at the same time, which not only increases the number of bits but also reduces machining time. In addition, it can save the time to replace the bite and improve the practicality. However, the inventors are not satisfied with this, and are actively conducting development to further improve efficiency and practicality.
このことを考慮して、本発明者は既存の不足部分について深く検討し、さらに本発明者の関連製品の開発に長く従事した経験により、積極的に解決方法を追求し、研究および発展のために努力を続け、最終的にＣＮＣ旋盤のバイトの同時多重操作機構を初めて作製することに成功した。これにより、バイトをさらに増加し、加工効率を上昇させる効果を達成する。 In view of this, the present inventor has made a deep examination of the existing shortcomings, and furthermore, based on the present inventor's long experience in developing related products, actively pursues solutions, and for research and development. , and finally succeeded in creating the simultaneous multiple operation mechanism for CNC lathe tools for the first time. As a result, the number of bites is further increased, and the effect of increasing the machining efficiency is achieved.
したがって、本発明の主な目的は、ＣＮＣ旋盤のバイトの同時多重操作機構を提供することであり、ＣＮＣ旋盤が複数のバイトを有することができ、また同時に加工することができ、効果的に加工効率および実用性を上昇させることができる。 Therefore, the main object of the present invention is to provide a simultaneous multiple operation mechanism for CNC lathe tools, so that the CNC lathe can have multiple tools and can process simultaneously, effectively Efficiency and utility can be increased.
本発明のもう１つの主な目的は、ＣＮＣ旋盤のバイトの同時多重操作機構を提供することであり、これによりＣＮＣ旋盤は複数のバイトを使用して同時加工することができ、バイトの数を大幅に増加させるだけでなく、加工時間およびバイトを交換する時間を短縮することができる。 Another main object of the present invention is to provide a mechanism for simultaneously multiplexing the bits of a CNC lathe, so that the CNC lathe can use multiple bits for simultaneous machining, and the number of bits can be reduced to Not only is it greatly increased, but the machining time and the time to change the cutting tool can be shortened.

本発明のＣＮＣ旋盤のバイトの同時多重操作機構を実際に応用するとき、図３、図４および図５に示すように、操作上、主軸台（１１）の上方に３つの２軸方向主軸２刃物台（２０）を有し、各２軸方向主軸２刃物台（２０）はＺ軸駆動セット（２２）を利用して動かす。各該２軸方向主軸２刃物台（２０）は、Ｙ軸スクリュ（２６）によって駆動される第１、２バイトセット（３０、３５）をそれぞれ有する。Ｙ軸スクリュ（２６）が右、左ネジ部分（２６１、２６２）を有することにより、各バイトは外径（Ｚ軸、Ｙ軸方向）加工を行うことができる。このほか、各２軸方向主軸２刃物台（２０）は第１、２バイトセット（３０、３５）を配置することができるが、右、左ネジ部分（２６１、２６２）を有するＹ軸スクリュ（２６）の設計を利用し、第１、２バイトセット（３０、３５）は相互に干渉しない。第１バイトセット（３０）が上昇するとき、第２バイトセット（３５）は同時に下降することができ、反対に、第１バイトセット（３０）が下降するとき、第２バイトセット（３５）は同時に上昇することができる。本発明の２軸方向主軸２刃物台（２０）は６つのバイト（３３、３８）を有し、多重操作の同時加工を行う目的を形成する。 When the simultaneous multiple operation mechanism of the CNC lathe tool of the present invention is applied in practice, as shown in FIGS. It has a turret (20) and each biaxial spindle 2 turret (20) is moved using a Z-axis drive set (22). Each said dual spindle dual tool post (20) has first and second bit sets (30, 35) respectively driven by Y-axis screws (26). Since the Y-axis screw (26) has right and left threaded portions (261, 262), each bit can perform outer diameter (Z-axis, Y-axis direction) processing. In addition, each biaxial direction spindle 2 turret (20) can be arranged with 1st and 2nd bit sets (30, 35), Y-axis screw ( 26), the first and second byte sets (30, 35) do not interfere with each other. When the first set of bytes (30) rises, the second set of bytes (35) can fall at the same time; can rise at the same time.

前記構造設計および動作の説明により、以下のことがわかる。本発明のＣＮＣ旋盤のバイトの同時多重操作機構は、主軸台（１１）前方の２軸方向くし刃型刃物台（４０）が保持されており、この２軸方向くし刃型刃物台（４０）は外径、内径の旋削および穴あけ（Ｚ軸方向およびＸ軸方向）加工を行うことができる。さらに、主軸台（１１）上方の３つの２軸方向主軸２刃物台（２０）の設計により、各該２軸方向主軸２刃物台（２０）のバイト（３３、３８）間は互いに干渉しない。したがって、同一時点に主軸軸心（１２）の被加工物方向に加工を行うことができ、各２軸方向主軸２刃物台（２０）は異なる寸法の外径加工を行うことができる。同一時間に２軸方向くし刃型刃物台（４０）も主軸軸心（１２）方向に外径、内径の旋削および穴あけ加工を行うことができ、ＣＮＣ旋盤は同一時点に複数のバイト（３３、３８）を使用することができる。加工時間を短縮するだけでなく、バイトの不足を解決する機構である。本機構はコンピュータ制御であるため、操作が容易であるだけでなく、コンピュータ上でバイトの摩耗補正を精確に行い、加工精度を上昇させることができる。本機構は、市販の使い捨てバイトおよび成型バイトを使用することができる。したがって、バイト（３３、３８）の数を増加するだけでなく、加工時間およびバイトを交換する時間を大幅に短縮することができ、加工効率を効果的に上昇させ、実用性が増加する。付加価値を上昇させることができ、経済的効果、利益をさらに上昇させることができる。 From the structural design and operational description above, the following can be seen. The simultaneous multiple operation mechanism for the tool of the CNC lathe of the present invention holds a biaxial gang tool post (40) in front of the headstock (11). can perform OD, ID turning and drilling (Z and X directions). Furthermore, due to the design of the three 2-axis spindle 2-turrets (20) above the headstock (11), the bites (33, 38) of each 2-axis spindle 2-turrets (20) do not interfere with each other. Therefore, machining can be performed in the direction of the work piece along the spindle axis (12) at the same time, and each of the two-axis direction spindle and two tool rests (20) can perform outside diameter machining of different dimensions. The two-axis gang type tool post (40) can also perform turning and drilling of the outer diameter and inner diameter in the direction of the spindle axis (12) at the same time, and the CNC lathe can operate multiple tools (33, 38) can be used. This mechanism not only shortens the machining time, but also solves the shortage of cutting tools. Since this mechanism is computer-controlled, it is not only easy to operate, but it also enables accurate correction of cutting tool wear on the computer to improve machining accuracy. The mechanism can use commercially available disposable and molded bites. Therefore, not only can the number of cutting tools (33, 38) be increased, but also the machining time and the cutting tool replacement time can be greatly reduced, effectively increasing the machining efficiency and increasing the practicability. Added value can be increased, and economic effects and profits can be further increased.
