Description

この発明は、工作機械のワーク加工領域で発生する切粉や切削油が機械の機構領域に侵入するのを防止するための隔壁の構造に関するもので、特に隔壁の垂直面に沿って移動する部材の移動通路に沿って当該隔壁に設けられる開口を閉鎖する保護カバーの構造に特徴がある隔壁構造に関するものである。 The present invention relates to the structure of a partition wall for preventing chips and cutting oil generated in the work area of a machine tool from entering the mechanical area of the machine tool, and in particular, a member moving along a vertical surface of the partition wall. It relates to a partition wall structure characterized by a structure of a protective cover that closes an opening provided in the partition wall along the moving passage of the above.

工作機械でワークを加工する際には、加工部に切削油が供給され、加工部から切粉が飛散する。飛散した切削油や切粉が機械の機構領域に配置される歯車、送りねじ、ガイド溝などに付着して機械が損傷するのを防ぐために、ワークの加工を行う加工領域と機械を動作させるための装置を配置した機構領域とを区画する隔壁、保護カバー、開閉扉などが設けられる。 When machining a workpiece with a machine tool, cutting oil is supplied to the machined part, and chips are scattered from the machined part. To operate the machine and the machining area where the workpiece is machined in order to prevent the scattered cutting oil and chips from adhering to the gears, feed screws, guide grooves, etc. located in the mechanical area of the machine and damaging the machine. A partition wall, a protective cover, an opening / closing door, etc. are provided to partition the mechanism area in which the device is arranged.

例えば、タレット旋盤において、図４に示すように、主軸軸線と直交する鉛直面を備えた隔壁１１側に主軸チャック５とタレットヘッド４とを配置した場合、主軸チャック５やタレットヘッドの割出装置３が隔壁１１を貫通して設けられることになる。そして、ワークを加工する際にタレットヘッド４、従って当該タレットヘッドを割出回転する割出装置３は、主軸軸線ａに近接及び離隔する方向に移動するので、隔壁１１には、その移動を許容するための開口８が設けられ、この開口を閉鎖するための保護カバーが設けられる。 For example, in a turret lathe, as shown in FIG. 4, when the spindle chuck 5 and the turret head 4 are arranged on the partition wall 11 side having a vertical plane orthogonal to the spindle axis, the spindle chuck 5 and the turret head indexing device 3 will be provided so as to penetrate the partition wall 11. Then, when the workpiece is machined, the turret head 4, and therefore the indexing device 3 for indexing and rotating the turret head, moves in the direction of approaching and separating from the spindle axis a, so that the partition wall 11 is allowed to move. An opening 8 is provided to close the opening, and a protective cover is provided to close the opening.

割出装置３が主軸軸線ａ側に移動したときに、反主軸軸線側に生ずる開口は、その周縁に密着して滑り移動する１枚の滑り板３４で閉鎖することができる。しかし、割出装置の主軸軸線側にある開口は、１枚の滑り板で閉鎖すると割出装置３が主軸軸線ａ側に移動したときに主軸チャック５と当該滑り板とが干渉するので、伸縮可能なカバー（伸縮カバー）で閉鎖する必要がある。この伸縮構造として、割出装置３の移動方向に短いストロークで滑り移動可能に摺接する羽板３３の多数枚を積重した構造の伸縮カバー３０が多く用いられている。 When the indexing device 3 moves to the spindle axis a side, the opening generated on the anti-spindle axis side can be closed by a single sliding plate 34 that slides in close contact with the peripheral edge thereof. However, if the opening on the spindle axis side of the indexing device is closed by one sliding plate, the spindle chuck 5 and the sliding plate interfere with each other when the indexing device 3 moves to the spindle axis a side, so that the opening can be expanded and contracted. Must be closed with a possible cover (expandable cover). As this telescopic structure, a telescopic cover 30 having a structure in which a large number of blade plates 33 that are slidably and slidably in contact with each other in the moving direction of the indexing device 3 are stacked is often used.

このような構造の伸縮カバーにおいて、旋盤がスラント形の、すなわち上面７を斜めにしたベッド６を備えた旋盤の場合には、割出装置３がベッド上面７と平行に斜めに移動ｓするので、伸縮カバー３０も斜め方向に伸縮するように設けなければならない。積層した複数枚の羽板３３からなる伸縮カバー３０は、互いに摺接する羽板相互の密着状態を保つために、その移動方向に延在する、例えば断面コの字形のガイド溝３８（３８ａ、３８ｂ）を備えたガイド材３７で案内する必要がある。ガイド溝３８は、積層された羽板３３の両端を案内するように設けるのが望ましい。 In the telescopic cover having such a structure, when the lathe is slant-shaped, that is, the lathe is provided with the bed 6 having the upper surface 7 slanted, the indexing device 3 moves diagonally in parallel with the bed upper surface 7. The telescopic cover 30 must also be provided so as to expand and contract in an oblique direction. The telescopic cover 30 composed of a plurality of laminated wing plates 33 extends in the moving direction in order to maintain a close contact state between the wing plates that are in sliding contact with each other, for example, a guide groove 38 (38a, 38b) having a U-shaped cross section. It is necessary to guide with the guide material 37 provided with). It is desirable that the guide groove 38 is provided so as to guide both ends of the laminated wing plates 33.

上記のような構造の伸縮カバーの羽板３３は、移動部材、すなわち上記の例では割出装置３に連動して移動するため、割出装置３が後退（主軸軸線から離れる）したときに、ガイド溝３８の先端側、すなわち主軸チャック５側に後退した羽板の厚さに相当する分の隙間が生ずる。主軸軸線ａの上方に配置された刃物台については、このようなガイド溝を備えた伸縮カバーを設けたとしても、上記隙間に切削油や切粉が入り込む確率は少ないし、もし、入り込んだとしても、重力又は主軸軸線側である下方に移動する羽板によって押し出されるので、問題は生じない。 Since the blade 33 of the telescopic cover having the above structure moves in conjunction with the moving member, that is, the indexing device 3 in the above example, when the indexing device 3 retracts (away from the spindle axis), it moves. A gap corresponding to the thickness of the wing plate retracted to the tip end side of the guide groove 38, that is, to the spindle chuck 5 side is generated. For the tool post located above the spindle axis a, even if a telescopic cover provided with such a guide groove is provided, there is little probability that cutting oil or chips will enter the gap, and if it does, However, there is no problem because it is pushed out by gravity or a wing plate that moves downward on the spindle axis side.

しかし、主軸軸線ａの下方に配置された刃物台について、上記のような伸縮カバー３０を設けると、その下側のガイド溝３８ｂの隙間に入り込んだ切削油や切粉は、羽板３３が積層されている側に留まることになり、割出装置３が移動するごとに、これに伴って移動する羽板に押されて繰り返しガイド溝３８ｂ内を移動し、羽板やガイド材に損傷を与える。すなわちガイド溝３８ｂに入り込んだ切粉は、ガイド溝３８ｂ内から排出されることがなく、いつまでも留まって羽板３３と共にガイド溝３８ｂ内を移動し、伸縮カバー３０を損傷させるという問題が起こる。 However, if the expansion / contraction cover 30 as described above is provided for the tool post arranged below the spindle axis a, the cutting oil and chips that have entered the gap of the guide groove 38b on the lower side thereof are laminated with the blade plate 33. Every time the indexing device 3 moves, it is pushed by the moving wing plate and repeatedly moves in the guide groove 38b, damaging the wing plate and the guide material. .. That is, the chips that have entered the guide groove 38b are not discharged from the guide groove 38b, but stay indefinitely and move in the guide groove 38b together with the wing plate 33, causing a problem that the telescopic cover 30 is damaged.

上記の問題を避けるために、下側のガイド材を設けないで、上側のガイド溝３８ａのみで羽板３３を案内することも試みられている。しかし、そのような構造の場合には、ガイド溝を設けていない側で羽板３３相互を密着させる力が作用しないので、羽板の移動動作が不安定になったり、羽板相互の隙間に切削油や細かい切粉が入り込んだりして、羽板３３の滑り動作が不安定になったり、羽板３３が損傷するという問題が発生した。 In order to avoid the above problem, it is also attempted to guide the wing plate 33 only by the upper guide groove 38a without providing the lower guide material. However, in the case of such a structure, since the force that brings the blades 33 into close contact with each other does not act on the side where the guide groove is not provided, the movement of the blades becomes unstable or the gap between the blades becomes small. There has been a problem that the sliding operation of the wing plate 33 becomes unstable or the wing plate 33 is damaged due to the entry of cutting oil and fine chips.

この発明は、上記のような問題を解決するためになされたもので、工作機械の加工領域と機構領域とを区画する隔壁を貫通して斜めに移動する傾斜移動部材の移動通路となる開口を遮蔽するための伸縮カバーを備え、当該伸縮カバーが積層された複数枚の羽板を備えている隔壁構造において、羽板の伸縮動作を不安定にすることがなく、かつ落下してくる切削油や切粉によって損傷することのない隔壁構造を提供することを課題としている。 The present invention has been made to solve the above-mentioned problems, and provides an opening that serves as a moving passage for an inclined moving member that moves diagonally through a partition wall that separates a machining area and a mechanical area of a machine tool. In a partition structure having a telescopic cover for shielding and a plurality of wing plates on which the telescopic covers are laminated, the cutting oil that falls without destabilizing the telescopic operation of the wing plates. An object of the present invention is to provide a partition structure that is not damaged by chips or chips.

この発明は、隔壁１１を貫通する傾斜移動部材３の当該移動を妨げないために設けられる開口８を閉鎖する保護カバー１を、水平方向に滑り移動するすべり板（水平移動板）２１と鉛直方向に伸縮する伸縮カバー１０とで形成する隔壁構造を提供することにより、上記課題を解決したものである。 In the present invention, the protective cover 1 for closing the opening 8 provided so as not to hinder the movement of the inclined moving member 3 penetrating the partition wall 11 is slidably moved in the horizontal direction with the sliding plate (horizontal moving plate) 21 in the vertical direction. The above problem is solved by providing a partition wall structure formed by the telescopic cover 10 that expands and contracts.

すなわちこの発明の隔壁構造は、ワークを加工する加工領域と主軸駆動装置や刃物台駆動装置などが配置されている機構領域とを区画する隔壁１１であって、当該隔壁を貫通して斜めに移動する、例えば工具ヘッド４の割出装置などの傾斜移動部材３の当該斜めの移動を許容するために隔壁に設けられる開口８を閉鎖する伸縮カバーを備えた隔壁の構造に関し、前記開口８が、傾斜移動部材３の斜めの移動に伴う水平方向の移動と連動する水平移動板２１と、この水平移動板を案内する鉛直移動部材１２と、この鉛直移動部材と固定の隔壁１１との間に鉛直方向に滑り移動自在に積層された複数枚の羽板１３と、隔壁１１に固定されて複数枚の羽板１３の両端部を案内する鉛直方向のガイド溝１８とを備えている隔壁構造である。 That is, the partition wall structure of the present invention is a partition wall 11 that divides a processing area for processing a work and a mechanism area in which a spindle drive device, a tool post drive device, and the like are arranged, and moves diagonally through the partition wall. With respect to the structure of the partition wall provided with a telescopic cover for closing the opening 8 provided in the partition wall in order to allow the oblique movement of the tilting moving member 3 such as the indexing device of the tool head 4, the opening 8 comprises. A horizontal moving plate 21 that interlocks with the horizontal movement of the inclined moving member 3 due to an oblique movement, a vertical moving member 12 that guides the horizontal moving plate, and a vertical movement member between the vertical moving member and the fixed partition wall 11. It is a partition wall structure including a plurality of blade plates 13 that are laminated so as to be slidably movable in a direction, and a vertical guide groove 18 that is fixed to the partition wall 11 and guides both ends of the plurality of blade plates 13. ..

複数枚の羽板１３のそれぞれの一方又は両方の端部に鉛直方向下方に伸びる案内縁１４を設け、この案内縁１４がガイド溝１８で案内されるようにすれば、羽板１３の振れ動きを防止することができ、羽板１３のより円滑な移動が可能になる。また、複数枚の羽板１３のそれぞれの両端部を直角に屈曲した屈曲部１５、１６とし、積重された羽板１３が屈曲部１５、１６においても積重されて互いに摺接しかつガイド溝１８で案内される構造とすることで、伸縮カバー１０の剛性を高くできると共に移動動作をより安定にすることができる。 If a guide edge 14 extending downward in the vertical direction is provided at one or both ends of each of the plurality of wing plates 13 and the guide edge 14 is guided by the guide groove 18, the wing plate 13 swings. Can be prevented, and the wing plate 13 can be moved more smoothly. Further, both ends of the plurality of blade plates 13 are bent at right angles to form bent portions 15 and 16, and the stacked blade plates 13 are also stacked at the bent portions 15 and 16 so as to be in sliding contact with each other and a guide groove. By adopting the structure guided by 18, the rigidity of the telescopic cover 10 can be increased and the moving operation can be made more stable.

この発明によれば、隔壁１１を貫通する部材３の斜めの移動を鉛直移動と水平移動に分解し、伸縮カバー１０の羽板１３を鉛直方向に移動させることにより、羽板１３の両端をガイド溝１８で案内することができ、羽板１３の安定な移動動作を実現でき、かつガイド溝１８内への切削油や切粉の侵入による羽板１３やガイド材１７の損傷を防止できる。 According to the present invention, the diagonal movement of the member 3 penetrating the partition wall 11 is decomposed into vertical movement and horizontal movement, and the wing plate 13 of the telescopic cover 10 is moved in the vertical direction to guide both ends of the wing plate 13. It can be guided by the groove 18, a stable moving operation of the blade plate 13 can be realized, and damage to the blade plate 13 and the guide material 17 due to the intrusion of cutting oil and chips into the guide groove 18 can be prevented.

すなわちこの発明により、伸縮カバーの動作方向が鉛直であることから、切粉のガイド溝への侵入及び堆積が防止され、伸縮カバー１０の動作が安定すると共に、羽板１３やガイド材１７の損傷を防止できる効果がある。 That is, according to the present invention, since the operating direction of the telescopic cover is vertical, invasion and accumulation of chips in the guide groove are prevented, the operation of the telescopic cover 10 is stabilized, and the wing plate 13 and the guide material 17 are damaged. Has the effect of preventing.

更に、傾斜移動部材３の斜めの移動ストロークに対する伸縮カバー１０の鉛直方向のストロークが短くなり、羽板１３の枚数を少なくでき、伸縮カバー１０の動作剛性も高くできるという効果がある。 Further, the vertical stroke of the telescopic cover 10 with respect to the diagonal movement stroke of the tilting moving member 3 is shortened, the number of blade plates 13 can be reduced, and the operating rigidity of the telescopic cover 10 can be increased.

以下、実施例を示す図面を参照して、この発明を更に説明する。図１は、主軸チャック５及び割出装置３が貫通している隔壁１１を加工領域側から主軸軸線ａ方向に見た図で、割出装置３に取り付けられているタレットヘッド４が想像線で示されている。 Hereinafter, the present invention will be further described with reference to the drawings showing examples. FIG. 1 is a view of the partition wall 11 through which the spindle chuck 5 and the indexing device 3 penetrate from the machining area side in the direction of the spindle axis a, and the turret head 4 attached to the indexing device 3 is an imaginary line. It is shown.

割出装置３のケーシングの先端（加工領域側の端部）には、鉛直移動部材１２の開口９の周囲に摺接して滑り移動する水平移動板２１が固定されている。開口９の水平方向の長さは、隔壁の開口８の水平方向の長さと等しい。水平移動板２１は、鉛直移動部材１２に設けた水平ガイド２２で水平方向に自由移動自在に案内されている。 A horizontal moving plate 21 that slides and slides around the opening 9 of the vertical moving member 12 is fixed to the tip of the casing of the indexing device 3 (the end on the processing region side). The horizontal length of the opening 9 is equal to the horizontal length of the opening 8 of the bulkhead. The horizontal moving plate 21 is guided by a horizontal guide 22 provided on the vertically moving member 12 so as to be freely movable in the horizontal direction.

鉛直移動部材１２は、隔壁の開口８の鉛直方向の長さと等しいストロークで鉛直方向に自由移動自在で、この鉛直移動部材１２の主軸軸線ａ側に鉛直方向に伸縮する伸縮カバー１０が設けられている。鉛直移動部材１２の反主軸軸線側には、開口８の下側の周面に摺接する１枚の板材からなる滑り板２４が固定されている。 The vertical moving member 12 can freely move in the vertical direction with a stroke equal to the length of the opening 8 of the partition wall in the vertical direction, and a telescopic cover 10 that expands and contracts in the vertical direction is provided on the spindle axis a side of the vertical moving member 12. There is. On the anti-spindle axis side of the vertically moving member 12, a sliding plate 24 made of a single plate material that is in sliding contact with the peripheral surface below the opening 8 is fixed.

図２及び図３は、伸縮カバー１０の詳細構造を示した斜視図である。図３は、割出装置が主軸チャック側に移動した状態を示し、図２は、割出装置が反主軸チャック側に移動した状態を示している。図２及び図３は、羽板１３を案内する手前側のガイド材を省略した状態で示している。 2 and 3 are perspective views showing the detailed structure of the telescopic cover 10. FIG. 3 shows a state in which the indexing device is moved to the spindle chuck side, and FIG. 2 shows a state in which the indexing device is moved to the anti-spindle chuck side. 2 and 3 show a state in which the guide material on the front side for guiding the blade plate 13 is omitted.

伸縮カバー１０は、互いに摺動自在に積重された複数枚の羽板１３を備えている。各羽板１３の一方の端部は、羽板１３の移動方向に伸びる案内縁１４を備えている。案内縁１４の側縁と羽板の他方の端部は、直角に屈曲された屈曲部１５、１６となっている。複数枚の羽板１３は、その移動方向の寸法がすべて等しく、案内縁１４の長さが最も短い羽板が鉛直移動部材１２に固定され、案内縁１４の最も長い羽板１３ａが隔壁１１に固定されている。案内縁１４の最も短い羽板１３ｂと最も長い羽板１３ａとの間の羽板１３の案内縁１４の長さは、等しい寸法差で順次長くなっている。 The telescopic cover 10 includes a plurality of blade plates 13 slidably stacked on each other. One end of each wing plate 13 is provided with a guide edge 14 extending in the moving direction of the wing plate 13. The side edge of the guide edge 14 and the other end of the wing plate are bent portions 15 and 16 that are bent at right angles. The plurality of wing plates 13 have the same dimensions in the moving direction, the wing plate having the shortest guide edge 14 length is fixed to the vertical moving member 12, and the longest wing plate 13a of the guide edge 14 is attached to the partition wall 11. It is fixed. The length of the guide edge 14 of the wing plate 13 between the shortest wing plate 13b of the guide edge 14 and the longest wing plate 13a is sequentially increased by the same dimensional difference.

複数枚の羽板１３は、案内縁１４の短い羽板がそれより長い案内縁を持つ羽板の内側に順次嵌り込むようにして積重されている。羽板両端の屈曲部１５、１６の高さは、積重したときにその頂辺１５ａ、１６ａが同一高さとなるようにしてあり、この屈曲部が隔壁１１に固定した断面コの字形ないし逆Ｌ形のガイド材１７によって形成される断面コの字形のガイド溝１８に案内されて鉛直方向に自由移動可能となっている。案内縁１４の最も短い羽板１３ａを除く他の羽板の前縁部と案内縁１４の後端部には、その内側に納まっている羽板のストロークを規制する突起（図では各羽板の裏側になるため、示されていない。）が設けられている。 The plurality of blade plates 13 are stacked so that the short blade plates of the guide edges 14 are sequentially fitted inside the blade plates having the longer guide edges. The heights of the bent portions 15 and 16 at both ends of the wing plate are set so that the top portions 15a and 16a are at the same height when stacked, and the bent portions are fixed to the partition wall 11 and have a U-shaped cross section or an inverted shape. It is guided by a guide groove 18 having a U-shaped cross section formed by the L-shaped guide material 17 and can freely move in the vertical direction. The leading edge of the other blades except the shortest blade 13a of the guide edge 14 and the rear end of the guide edge 14 have protrusions (in the figure, each blade) that regulate the stroke of the blades contained therein. (Not shown) is provided because it is on the back side of.

次に図１を参照して、割出装置３が主軸軸線ａ側に向けて進出及び後退するときの伸縮カバーの動作について説明する。割出装置３が主軸軸線ａに接近する方向に動くと、その移動に伴って水平移動板２１が図１で左方向に動き、伸縮カバー１０が縮退する。一方、割出装置３が主軸軸線ａから離れる方向に移動すると、水平移動板２１が図１で右方向に動き、伸縮カバー１０が鉛直方向に伸長する。すなわち、この発明の保護カバー１の機能は、割出装置３の斜め方向の移動ｓによって水平移動板２１の水平方向の移動ｈと、伸縮カバー１０の鉛直方向ｖの伸縮動作の合成によって実現される。 Next, with reference to FIG. 1, the operation of the telescopic cover when the indexing device 3 advances and retracts toward the spindle axis a side will be described. When the indexing device 3 moves in the direction approaching the spindle axis a, the horizontal moving plate 21 moves to the left in FIG. 1 along with the movement, and the telescopic cover 10 retracts. On the other hand, when the indexing device 3 moves away from the spindle axis a, the horizontal moving plate 21 moves to the right in FIG. 1 and the telescopic cover 10 extends in the vertical direction. That is, the function of the protective cover 1 of the present invention is realized by combining the horizontal movement h of the horizontal moving plate 21 and the vertical movement v of the telescopic cover 10 by the diagonal movement s of the indexing device 3. To.

従って、伸縮カバー１０の羽板１３を案内するガイド溝１８は、鉛直方向となり、ガイド溝内に落ち込んだ切削油や切粉は、鉛直移動部材１２が上下動する間に当該ガイド溝から脱落して、羽板に損傷を与えることがない。そして、積重された羽板のそれぞれは、その両端がガイド溝１８によって案内されて個々の羽板が搖動したり浮き上がったりすることがなくなり、羽板の動きが不安定になったり、積重した羽板の間に切粉が侵入して堆積する問題も解消される。 Therefore, the guide groove 18 that guides the blade plate 13 of the telescopic cover 10 is in the vertical direction, and the cutting oil and chips that have fallen into the guide groove fall out of the guide groove while the vertically moving member 12 moves up and down. Therefore, it does not damage the wing plate. At both ends of each of the stacked wing plates, the guide grooves 18 guide the individual wing plates so that the individual wing plates do not move or rise, and the movement of the wing plates becomes unstable or stacked. The problem of chips invading and accumulating between the sidings is also solved.

すなわち、この発明は、工作機械の加工領域を区画している隔壁１１を貫通する傾斜移動部材の通路に形成される当該隔壁の開口を両端をガイド溝に案内されて鉛直方向に伸縮する複数枚の羽板１３を備えた伸縮カバー１０と水平方向に自由移動する水平移動板２１とによって閉鎖したことを特徴とするもので、伸縮カバー１０の羽板１３を案内するガイド溝３８に侵入した切削油や切粉によって伸縮カバー１０が損傷するのを防止し、かつ伸縮カバーの羽板１３の案内を安定かつ確実に行うことができるようにしたものである。 That is, in the present invention, a plurality of sheets of the partition wall formed in the passage of the inclined moving member penetrating the partition wall 11 that divides the machining area of the machine tool are vertically expanded and contracted by being guided by guide grooves at both ends. It is characterized in that it is closed by the telescopic cover 10 provided with the wing plate 13 and the horizontal moving plate 21 that freely moves in the horizontal direction, and is cut into the guide groove 38 that guides the wing plate 13 of the telescopic cover 10. This is intended to prevent the telescopic cover 10 from being damaged by oil or chips, and to stably and reliably guide the wing plate 13 of the telescopic cover.
