Description

本発明は切削液を噴射する噴射装置と工作機械に関する。   The present invention relates to an injection device and a machine tool for injecting a cutting fluid.

工作機械は加工時に機内において切粉の堆積を防ぐ為に切削液を流す必要がある。工作機械は機内に切削液を供給する供給管を備える。供給管はノズルを備える。供給管に流れる切削液はノズルから噴射する。ノズルの向きは手動で変更できるが、切削液を局所的にしか噴射できない。切削液を広範囲に噴射するには、工作機械はノズルの本数を増やして大量の切削液を流す必要があった。切削液を吐出するポンプの容量は大きくなり消費電力も増大する。特許文献１が開示する切削液噴霧システムは、ノズルをロボットの先端に取り付け、該ノズルの姿勢及び位置を制御して液体の到達位置及び該到達位置における吹き付け角度を調整して切粉の除去作業を行う。   A machine tool needs to flow cutting fluid in order to prevent chip accumulation in the machine during processing. The machine tool includes a supply pipe for supplying cutting fluid into the machine. The supply pipe includes a nozzle. The cutting fluid flowing into the supply pipe is ejected from the nozzle. The direction of the nozzle can be changed manually, but the cutting fluid can only be sprayed locally. In order to inject the cutting fluid over a wide range, the machine tool needs to increase the number of nozzles and flow a large amount of cutting fluid. The capacity of the pump that discharges the cutting fluid increases and the power consumption also increases. The cutting fluid spraying system disclosed in Patent Document 1 has a nozzle attached to the tip of a robot and controls the posture and position of the nozzle to adjust the liquid arrival position and the spray angle at the arrival position to remove chips. I do.

特開平１０−１１８８８４号公報Japanese Patent Laid-Open No. 10-118884

特許文献１に記載の切削液噴霧システムは、ノズルを取り付けたロボットを駆動しなければならないので、工作機械の消費電力が増大するという問題点があった。工作機械は、切削液を広範囲に噴射する場合、ノズルの向きを頻繁に変える必要があるので、ロボットのモータに過大な負荷がかかる可能性があった。   The cutting fluid spraying system described in Patent Document 1 has a problem that the power consumption of the machine tool increases because the robot to which the nozzle is attached has to be driven. When a machine tool sprays cutting fluid over a wide range, it is necessary to frequently change the direction of the nozzle, so that an excessive load may be applied to the motor of the robot.

本発明の目的は、電力を使わずに、切削液を噴射する向きを変えることができる噴射装置と工作機械を提供することである。   The objective of this invention is providing the injection device and machine tool which can change the direction which injects cutting fluid, without using electric power.

本発明の請求項１に係る発明の噴射装置は、切削液を噴射する噴射部と、前記噴射部を回動可能に支持する支持機構と、前記切削液を前記噴射部に供給する供給管と、前記供給管が前記噴射部に供給する前記切削液の流れを、前記噴射部を回動する動力に変換する変換機構とを備える。   An injection device according to a first aspect of the present invention includes an injection unit that injects a cutting fluid, a support mechanism that rotatably supports the injection unit, and a supply pipe that supplies the cutting fluid to the injection unit. And a conversion mechanism for converting the flow of the cutting fluid supplied to the injection unit by the supply pipe into power for rotating the injection unit.

請求項１に係る発明の噴射装置では、変換機構は切削液の流れを噴射部を回動する動力に変換できる。故に噴射装置は、電力を消費することなく、噴射部の切削液を噴射する向きを変えることができる。切削液の流れという自然エネルギーを利用するので、環境衛生的にも好ましい。噴射装置は切削液を噴射する向きを変えることができるので、広範囲に切削液を噴射できる。故に噴射装置は複数台分の噴射範囲を一台で補うことができるので、噴射装置の設置台数の削減、噴射装置の設備コストの削減、切削液の流量の削減等が可能である。   In the injection device according to the first aspect of the present invention, the conversion mechanism can convert the flow of the cutting fluid into power for rotating the injection unit. Therefore, the injection device can change the direction in which the cutting fluid of the injection unit is injected without consuming electric power. Since natural energy called the flow of the cutting fluid is used, it is preferable from the viewpoint of environmental hygiene. Since the spraying device can change the direction in which the cutting fluid is sprayed, the cutting fluid can be sprayed over a wide range. Therefore, since the injection device can compensate the injection range for a plurality of devices, it is possible to reduce the number of installed injection devices, reduce the equipment cost of the injection devices, reduce the flow rate of the cutting fluid, and the like.

請求項２に係る発明の噴射装置は、請求項１に記載の発明の構成に加え、前記変換機構は、前記供給管に設け、前記供給管が供給する前記切削液の流れを回転力に変換する回転力変換部と、前記回転力変換部が変換した前記回転力を、前記噴射部を回動する前記動力に変換する動力変換部とを備える。回転力変換部が切削液の流れを回転力に変換するので、切削液の流れという自然エネルギーを、噴射部を回動する動力として利用することが容易となる。   According to a second aspect of the invention, in addition to the configuration of the first aspect of the invention, the conversion mechanism is provided in the supply pipe and converts the flow of the cutting fluid supplied by the supply pipe into a rotational force. And a power conversion unit that converts the rotational force converted by the rotational force conversion unit into the power that rotates the injection unit. Since the rotational force conversion unit converts the flow of the cutting fluid into the rotational force, it becomes easy to use natural energy called the flow of the cutting fluid as power for rotating the injection unit.

請求項３に係る発明の噴射装置は、請求項２に記載の発明の構成に加え、前記回転力変換部は、前記供給管が前記噴射部に供給する前記切削液を流入及び流出する密閉状の容器と、前記容器内に設け、前記容器内に流れる前記切削液を受けて回転する羽根車と、前記容器外に設け、前記羽根車と共に回転する回転板とを備え、前記動力変換部は、前記回転板の回転力を前記動力に変換するカム機構を備える。切削液を密閉状の容器内に流入及び流出することによって、切削液を漏らすことなく、羽根車を回転することができる。故に回転力変換部は、切削液の流れをそのまま羽根車の回転に利用できる。羽根車は容器外に設けた回転板を回転する。故に回転板は切削液の影響を受けずに回転できる。動力変換部はカム機構を用いることで、電力を消費せずに、回転板の回転力を噴射部を回動する動力に変換できる。   According to a third aspect of the present invention, in addition to the configuration of the second aspect of the present invention, the rotational force converting portion is a sealed shape in which the cutting fluid supplied from the supply pipe to the jetting portion flows in and out.

And a cam mechanism for converting the rotational force of the rotating plate into the power. By flowing the cutting fluid into and out of the sealed container, the impeller can be rotated without leaking the cutting fluid. Therefore, the rotational force converter can use the flow of the cutting fluid as it is for the rotation of the impeller. The impeller rotates a rotating plate provided outside the container. Therefore, the rotating plate can rotate without being affected by the cutting fluid. By using a cam mechanism, the power conversion unit can convert the rotational force of the rotating plate into power for rotating the injection unit without consuming electric power.

The machine tool 1 includes a base 2, a spindle mechanism (not shown), a table mechanism (not shown), a protective cover 3, and the like. The base unit 2 is a base of the machine tool 1. The spindle mechanism rotates the spindle on which the tool is mounted and is movable in the Z-axis direction. The table moving mechanism is provided on the upper part of the base part 2. The table moving mechanism can move a table (not shown) in the X-axis direction and the Y-axis direction. The table supports the workpiece on the upper surface. The machine tool 1 cuts the workpiece by controlling the spindle mechanism and the table moving mechanism. A substantially rectangular parallelepiped protective cover 3 is provided on the upper part of the base 2. The protective cover 3 covers the spindle mechanism and the table mechanism, and prevents dust and cutting fluid from splashing around.

The base portion 25 includes a fixed plate 26, an impeller housing portion 27, a shaft support portion 35, and a shaft support portion 37. The fixing plate 26 has a substantially rectangular shape having a predetermined thickness and a length in one direction. The fixing plate 26 is fixed to the inner surface (see FIG. 2) of the left side wall 5 of the protective cover 3. The fixed plate 26 includes a support surface 26A. The impeller accommodating portion 27 is provided in a cylindrical shape on the support surface 26A. The impeller accommodating portion 27 includes an inflow portion 29 in the upper left portion and an outflow portion 31 in the lower left portion. The inflow portion 29 protrudes upward in a rectangular shape and includes an inflow hole 30 in the center. The outflow portion 31 protrudes in a rectangular shape obliquely to the left and has an outflow port 32 in the center. The cylindrical shaft support portion 35 is provided at the inner center of the impeller housing portion 27 on the support surface 26A.

The cylindrical shaft support portion 37 is provided at the lower end side of the support surface 26A and at the center in the left-right direction. The shaft support portion 37 rotatably supports a nozzle support portion 60 (see FIG. 7) which will be described later.

図６を参照し、羽根車４０を説明する。羽根車４０は回転軸４１と複数の羽根４２を備える。複数の羽根４２は矩形状且つ回転軸４１を中心に放射状に配置する。羽根４２の枚数は一例として１２枚である。羽根車４０はベース部２５の羽根車収容部２７内に収容する。回転軸４１の一端部は軸支部３５の穴部３５Ａ（図５参照）に遊挿する。羽根車４０を収容した羽根車収容部２７は蓋部３８（図４，図７参照）で塞いで密閉する。蓋部３８は略円形状の板であって中心に貫通穴（図示略）を備える。回転軸４１の他端部は貫通穴から前方に突出する（図７参照）。故に羽根車４０は羽根車収容部２７内で回転可能となる。羽根車収容部２７は内側を切削液で満たす。羽根車４０の羽根４２は流入穴３０の直下に位置する。故に流入穴３０から流入する切削液は羽根４２を押し下げる。羽根車４０は正面視反時計回りに回転する（図８参照）。   The impeller 40 will be described with reference to FIG. The impeller 40 includes a rotating shaft 41 and a plurality of blades 42. The plurality of blades 42 are arranged in a rectangular shape and radially about the rotation shaft 41. The number of blades 42 is 12 as an example. The impeller 40 is accommodated in the impeller accommodating portion 27 of the base portion 25.

The lid portion 38 is a substantially circular plate and includes a through hole (not shown) at the center. The other end of the rotating shaft 41 protrudes forward from the through hole (see FIG. 7). Therefore, the impeller 40 can rotate in the impeller accommodating portion 27. The impeller accommodating portion 27 fills the inside with cutting fluid. The blades 42 of the impeller 40 are located directly below the inflow hole 30. Therefore, the cutting fluid flowing from the inflow hole 30 pushes down the blade 42. The impeller 40 rotates counterclockwise when viewed from the front (see FIG. 8).

図７を参照し、回転板５０を説明する。回転板５０は略円形状の板である。回転板５０は中心に筒状の被軸支部５２を備える。回転板５０は被軸支部５２の穴部（図示略）に蓋部３８の貫通穴から前方に突出する回転軸４１の他端部を挿入して固定する。故に回転板５０は羽根車４０と一体的に回転する。回転板５０は表面５０Ａにおいて被軸支部５２から径方向外側に離れる位置にガイド部５５を備える。表面５０Ａは蓋部３８に対向する面とは反対側の面である。円柱状のガイド部５５は縮径する棒状のガイド軸５６を先端側に備える。   The rotating plate 50 will be described with reference to FIG. The rotating plate 50 is a substantially circular plate. The rotating plate 50 includes a cylindrical supported portion 52 at the center. The rotating plate 50 is fixed by inserting the other end portion of the rotating shaft 41 protruding forward from the through hole of the lid portion 38 into a hole portion (not shown) of the shaft support portion 52. Therefore, the rotating plate 50 rotates integrally with the impeller 40. The rotary plate 50 includes a guide portion 55 at a position away from the pivot support portion 52 radially outward on the surface 50A. The surface 50 </ b> A is a surface opposite to the surface facing the lid portion 38.

The nozzle support portion 60 has a bottomed cylindrical shape with one end opened. The nozzle support portion 60 includes a cylindrical body 61, a bottom wall 62, an inflow portion 63, and a shaft portion 66. The cylindrical body 61 includes two supply holes 68 at the lower part of the outer surface. The bottom wall 62 closes the open end of the cylindrical body 61 on the base portion 25 side. The inflow part 63 is provided in the upper part of the cylinder 61, and protrudes in a rectangular shape upward. The inflow portion 63 has an inflow hole 64 in the center. The cylindrical inflow port 65 is inserted and fixed to the inflow hole 64 from above. The shaft 66 is cylindrical and is provided at the center of the inner surface of the bottom wall 62. The bottom wall 62 includes a support shaft (not shown) at the center of the outer surface. The support shaft is coaxial with the shaft portion 66, and is loosely inserted into a hole 37 </ b> A (see FIG. 6) of the shaft support portion 37 of the base portion 25. Therefore, the nozzle support portion 60 can rotate around the shaft support portion 37.

図３，図８を参照し、リンク部材７０を説明する。図３に示す如く、リンク部材７０は幅の細い長方形状の板部材であり上下方向に配置する。リンク部材７０は下端部に基端部７１を備える。基端部７１は正面視円形状且つノズル支持部６０の筒体６１の開口端形状に対応する。基端部７１は中心部に貫通穴（図示略）を備える。基端部７１は筒体６１の開口端を塞ぐように配置する。基端部７１の貫通穴はノズル支持部６０の軸部６６の穴部６６Ａ（図７参照）の位置に対応する。固定具８０は貫通穴と穴部６６Ａとに挿入しリンク部材７０をノズル支持部６０に固定する。基端部７１はノズル支持部６０と共に一体して回転する。   The link member 70 will be described with reference to FIGS. As shown in FIG. 3, the link member 70 is a narrow rectangular plate member and is arranged in the vertical direction. The link member 70 includes a proximal end portion 71 at the lower end portion. The base end portion 71 has a circular shape when viewed from the front and corresponds to the opening end shape of the cylindrical body 61 of the nozzle support portion 60. The base end portion 71 includes a through hole (not shown) at the center. The base end portion 71 is disposed so as to close the open end of the cylindrical body 61. The through hole of the base end portion 71 corresponds to the position of the hole portion 66 </ b> A (see FIG. 7) of the shaft portion 66 of the nozzle support portion 60. The fixing tool 80 is inserted into the through hole and the hole portion 66 </ b> A to fix the link member 70 to the nozzle support portion 60. The base end portion 71 rotates together with the nozzle support portion 60.

図８に示す如く、リンク部材７０は基端部７１とは反対側の遊端部７２にガイド溝７５を備える。ガイド溝７５は遊端部７２近傍から長手方向略中央位置まで延設する。ガイド溝７５は互いに対向する一対の内側面７５Ａ，７５Ｂを備える。内側面７５Ａは羽根車４０の中心から離れる側の面（正面視右側の面）である。内側面７５Ｂは羽根車４０の中心に近い方の面（正面視左側の面）である。回転板５０のガイド軸５６はガイド溝７５に挿入する。図３，図４に示す如く、ガイド軸５６はガイド溝７５から前方に突出する先端部に被係止部５７を取り付ける。被係止部５７はガイド溝７５の幅よりも大きい円形状の板部材である。被係止部５７はガイド軸５６がガイド溝７５から抜けるのを防止する。   As shown in FIG. 8, the link member 70 includes a guide groove 75 in the free end portion 72 on the side opposite to the base end portion 71. The guide groove 75 extends from the vicinity of the free end portion 72 to a substantially central position in the longitudinal direction. The guide groove 75 includes a pair of inner side surfaces 75A and 75B that face each other. The inner side surface 75A is a surface away from the center of the impeller 40 (a surface on the right side when viewed from the front). The inner side surface 75B is a surface closer to the center of the impeller 40 (a surface on the left side when viewed from the front). The guide shaft 56 of the rotating plate 50 is inserted into the guide groove 75. As shown in FIGS. 3 and 4, the guide shaft 56 has a locked portion 57 attached to a tip portion protruding forward from the guide groove 75. The locked portion 57 is a circular plate member that is larger than the width of the guide groove 75. The locked portion 57 prevents the guide shaft 56 from coming out of the guide groove 75.

図３を参照し、噴射ノズル９１を説明する。噴射ノズル９１はノズル支持部６０の筒体６１に設けた二つの供給穴６８（図７参照）に対応する位置に設ける。噴射ノズル９１は可動部９２を備える。噴射ノズル９１は可動部９２を手動で屈曲することにより切削液を噴射する向きを自由に変更できる。図７に示す如く、切削液は流入口６５からノズル支持部６０の筒体６１内に流入し二つの供給穴６８から噴射ノズル９１（図３参照）に流れ、先端部から噴射する。   The injection nozzle 91 will be described with reference to FIG. The injection nozzle 91 is provided at a position corresponding to two supply holes 68 (see FIG. 7) provided in the cylindrical body 61 of the nozzle support portion 60. The injection nozzle 91 includes a movable part 92. The spray nozzle 91 can freely change the direction in which the cutting fluid is sprayed by manually bending the movable portion 92. As shown in FIG. 7, the cutting fluid flows into the cylindrical body 61 of the nozzle support portion 60 from the inlet 65, flows from the two supply holes 68 to the injection nozzle 91 (see FIG. 3), and is injected from the tip portion.

図８を参照し、第一流入管１７と第二流入管１８を説明する。第一流入管１７は切削液供給管１０（図２参照）に設けた流出穴（図示略）と、ベース部２５の羽根車収容部２７に設けた流入穴３０との間に取り付ける。第二流入管１８はベース部２５の羽根車収容部２７に設けた流出口３２と、ノズル支持部６０に設けた流入口６５との間に取り付ける。第一流入管１７と第二流入管１８は可撓性を有する材質（例えば樹脂やゴム等）で形成するのが好ましい。   The first inlet pipe 17 and the second inlet pipe 18 will be described with reference to FIG. The first inflow pipe 17 is attached between an outflow hole (not shown) provided in the cutting fluid supply pipe 10 (see FIG. 2) and an inflow hole 30 provided in the impeller housing portion 27 of the base portion 25. The second inflow pipe 18 is attached between the outflow port 32 provided in the impeller housing portion 27 of the base portion 25 and the inflow port 65 provided in the nozzle support portion 60. The first inflow pipe 17 and the second inflow pipe 18 are preferably formed of a flexible material (for example, resin or rubber).

図２，図８，図９を参照し、噴射装置２１の動作を説明する。図示外のポンプは切削液を吐出する。図２に示す如く、切削液は継ぎ手１５を介して保護カバー３内の切削液供給管１０に流れ、流出穴（図示略）から噴射装置２１の第一流入管１７に流れる。図８に示す如く、切削液は第一流入管１７を介して流入穴３０から羽根車収容部２７内部に流入する。羽根車収容部２７は内部を切削液で満たす。流入穴３０から流入した切削液は羽根車収容部２７内を通過し流出口３２から流出する。   The operation of the injection device 21 will be described with reference to FIGS. A pump (not shown) discharges cutting fluid. As shown in FIG. 2, the cutting fluid flows to the cutting fluid supply pipe 10 in the protective cover 3 through the joint 15, and flows from the outflow hole (not shown) to the first inflow pipe 17 of the injection device 21. As shown in FIG. 8, the cutting fluid flows into the impeller accommodating portion 27 from the inflow hole 30 through the first inflow pipe 17. The impeller accommodating portion 27 fills the interior with a cutting fluid. The cutting fluid flowing in from the inflow hole 30 passes through the impeller housing portion 27 and flows out from the outflow port 32.

羽根車４０は羽根車収容部２７内を通過する切削液の流れによって正面視反時計回りに回転する。即ち羽根車４０は切削液の流れを回転力に変換する。回転板５０は羽根車４０と一体して回転する。回転板５０に設けたガイド部５５は回転板５０の回転に伴って被軸支部５２を中心に正面視反時計回りに回動する。ガイド部５５は被軸支部５２を中心に回動する。ガイド部５５のガイド軸５６はリンク部材７０のガイド溝７５において内側面７５Ａ、７５Ｂを交互に繰り返し摺動する。ガイド軸５６が図８の状態から反時計回りに回動して右方から左方に移動する場合、ガイド軸５６は内側面７５Ｂに摺動しながら左方に付勢する。図９に示す如く、リンク部材７０の遊端部７２は基端部７１を中心に右方から左方に揺動する。基端部７１とノズル支持部６０はベース部２５の軸支部３７（図７参照）を中心に反時計回りに回転する。故に噴射ノズル９１の先端部は右方に揺動する。   The impeller 40 rotates counterclockwise when viewed from the front by the flow of the cutting fluid passing through the impeller accommodating portion 27. That is, the impeller 40 converts the flow of the cutting fluid into a rotational force. The rotating plate 50 rotates integrally with the impeller 40. The guide portion 55 provided on the rotating plate 50 rotates counterclockwise when viewed from the front with the pivotal support portion 52 as a center as the rotating plate 50 rotates. The guide part 55 rotates around the pivoted support part 52. The guide shaft 56 of the guide portion 55 slides alternately and repeatedly on the inner side surfaces 75A and 75B in the guide groove 75 of the link member 70. When the guide shaft 56 rotates counterclockwise from the state of FIG. 8 and moves from the right to the left, the guide shaft 56 is urged to the left while sliding on the inner surface 75B. As shown in FIG. 9, the free end 72 of the link member 70 swings from the right to the left around the base end 71. The base end portion 71 and the nozzle support portion 60 rotate counterclockwise around the shaft support portion 37 (see FIG. 7) of the base portion 25. Therefore, the tip of the injection nozzle 91 swings to the right.

次いで、ガイド軸５６が図９の状態から反時計回りに回動して左方から右方に移動する場合、ガイド軸５６は内側面７５Ａに摺動しながら右方に付勢する。図８に示す如く、リンク部材７０の遊端部７２は基端部７１を中心に左方から右方に揺動する。基端部７１とノズル支持部６０はベース部２５の軸支部３７を中心に時計回りに回転する。故に噴射ノズル９１の先端部は左方に揺動する。上述のように、回転板５０とリンク部材７０はカムを構成することで、羽根車４０の回転力をノズル支持部６０及び噴射ノズル９１の揺動動作に変換できる。   Next, when the guide shaft 56 rotates counterclockwise from the state of FIG. 9 and moves from the left to the right, the guide shaft 56 is urged to the right while sliding on the inner surface 75A. As shown in FIG. 8, the free end 72 of the link member 70 swings from the left to the right around the base end 71. The base end portion 71 and the nozzle support portion 60 rotate clockwise about the shaft support portion 37 of the base portion 25. Therefore, the tip of the injection nozzle 91 swings to the left. As described above, the rotating plate 50 and the link member 70 constitute a cam, so that the rotational force of the impeller 40 can be converted into the swing operation of the nozzle support portion 60 and the injection nozzle 91.

図８に示す如く、羽根車収容部２７の流出口３２から流出した切削液は第二流入管１８を流れ、流入口６５からノズル支持部６０内に流入する。ノズル支持部６０は内部を切削液で満たす。ノズル支持部６０内部の切削液は二つの供給穴６８から噴射ノズル９１内に流れる。噴射ノズル９１は切削液を噴射する。上述の通り、切削液が羽根車収容部２７内を流れ、羽根車４０が回転する間、噴射ノズル９１は左右に繰り返し揺動する。故に噴射ノズル９１は広範囲に切削液を噴射できる。故に噴射装置２１は少ない台数で、保護カバー３の内側下部及び基台部２上部に付着又は堆積する切粉を広範囲において洗い流すことができる。噴射装置２１は電力を消費しないので工作機械１の電力消費を節約できる。   As shown in FIG. 8, the cutting fluid flowing out from the outlet 32 of the impeller accommodating portion 27 flows through the second inlet pipe 18 and flows into the nozzle support portion 60 from the inlet 65. The nozzle support portion 60 fills the interior with a cutting fluid. The cutting fluid inside the nozzle support portion 60 flows into the injection nozzle 91 from the two supply holes 68. The spray nozzle 91 sprays cutting fluid. As described above, while the cutting fluid flows through the impeller accommodating portion 27 and the impeller 40 rotates, the injection nozzle 91 repeatedly swings left and right. Therefore, the injection nozzle 91 can inject the cutting fluid over a wide range. Therefore, the number of the injection devices 21 is small, and the chips adhering to or depositing on the inner lower part of the protective cover 3 and the upper part of the base part 2 can be washed out in a wide range. Since the injection device 21 does not consume power, the power consumption of the machine tool 1 can be saved.

以上説明したように、本実施形態の工作機械１は保護カバー３内に噴射装置２１を備える。噴射装置２１は切削液を噴射する装置である。噴射装置２１は切削液の流れを噴射ノズル９１を揺動する揺動力に変換できる。切削液は保護カバー３内の切削液供給管１０に流れ、噴射装置２１の第一流入管１７に流れる。切削液は第一流入管１７を介して流入穴３０から羽根車収容部２７の内部に流入する。羽根車収容部２７は内部を切削液で満たす。流入穴３０から流入した切削液は羽根車収容部２７内を通過し、流出口３２から流出する。羽根車４０は羽根車収容部２７内の切削液の流れによって正面視反時計回りに回転する。   As described above, the machine tool 1 according to this embodiment includes the injection device 21 in the protective cover 3. The spray device 21 is a device that sprays cutting fluid. The spray device 21 can convert the flow of the cutting fluid into a swinging force that swings the spray nozzle 91. The cutting fluid flows to the cutting fluid supply pipe 10 in the protective cover 3 and flows to the first inflow pipe 17 of the injection device 21. The cutting fluid flows into the impeller housing portion 27 from the inflow hole 30 through the first inflow pipe 17. The impeller accommodating portion 27 fills the interior with a cutting fluid. The cutting fluid flowing in from the inflow hole 30 passes through the impeller housing portion 27 and flows out from the outflow port 32. The impeller 40 rotates counterclockwise when viewed from the front by the flow of the cutting fluid in the impeller accommodating portion 27.

回転板５０は羽根車４０と一体して回転する。回転板５０に設けたガイド部５５は回転板５０の回転に伴って被軸支部５２を中心に正面視反時計回りに回動する。回動するガイド部５５はリンク部材７０のガイド溝７５において内側面７５Ａ、７５Ｂを交互に繰り返し摺動し左右に付勢する。リンク部材７０の遊端部７２は基端部７１を中心に左右に揺動する。基端部７１とノズル支持部６０はベース部２５の軸支部３７を中心に時計回り及び反時計回りに交互に回転する。噴射ノズル９１は所定角度の範囲で揺動する。   The rotating plate 50 rotates integrally with the impeller 40. The guide portion 55 provided on the rotating plate 50 rotates counterclockwise when viewed from the front with the pivotal support portion 52 as a center as the rotating plate 50 rotates. The rotating guide portion 55 slides alternately on the inner side surfaces 75A and 75B in the guide groove 75 of the link member 70 and urges it to the left and right. The free end portion 72 of the link member 70 swings left and right around the base end portion 71. The base end portion 71 and the nozzle support portion 60 rotate alternately clockwise and counterclockwise around the shaft support portion 37 of the base portion 25. The injection nozzle 91 swings within a predetermined angle range.

故に噴射装置２１は電力を消費することなく、噴射ノズル９１の切削液を噴射する向きを変えることができる。噴射装置２１は切削液の流れを利用するので余分な動力源を必要としない。噴射装置２１は噴射ノズル９１を揺動するので広範囲に切削液を噴射できる。故に噴射装置２１は複数台分の噴射範囲を一台で補うことができるので、工作機械１は噴射装置２１の設置台数の削減、噴射装置２１の設備コストの削減、切削液の流量の削減等が可能である。   Therefore, the injection device 21 can change the direction in which the cutting fluid of the injection nozzle 91 is injected without consuming electric power. Since the injection device 21 uses the flow of the cutting fluid, no extra power source is required. Since the injection device 21 swings the injection nozzle 91, the cutting fluid can be injected over a wide range. Therefore, since the injection device 21 can compensate the injection range for a plurality of units, the machine tool 1 can reduce the number of installation of the injection devices 21, reduce the equipment cost of the injection devices 21, reduce the flow rate of the cutting fluid, etc. Is possible.

上記実施形態では更に、切削液は密閉状の羽根車収容部２７内に流入する。羽根車４０は切削液を外部に漏らすことなく回転できる。故に噴射装置２１は切削液の流れを羽根車４０の回転に直接利用できる。羽根車４０は羽根車収容部２７外に設けた回転板５０を回転する。噴射装置２１は回転板５０のガイド軸５６とリンク部材７０を用いることで、電力を消費せずに回転板５０の回転力を噴射ノズル９１を揺動する揺動力に変換できる。   Further, in the above embodiment, the cutting fluid flows into the sealed impeller accommodating portion 27. The impeller 40 can rotate without leaking the cutting fluid to the outside. Therefore, the injection device 21 can directly use the flow of the cutting fluid to rotate the impeller 40. The impeller 40 rotates a rotating plate 50 provided outside the impeller accommodating portion 27. By using the guide shaft 56 and the link member 70 of the rotating plate 50, the injection device 21 can convert the rotational force of the rotating plate 50 into a swinging force that swings the spray nozzle 91 without consuming electric power.

上記実施形態では更に、ガイド軸５６は回転板５０の回転中心から径方向外側に離間する位置に設ける。ガイド軸５６は回転板５０の回転によって回転中心に対して左右両側に大きく移動する。リンク部材７０の遊端部７２は基端部７１に対して広範囲に大きく揺動する。故に基端部７１とノズル支持部６０の回転角度は大きくなるので、噴射ノズル９１はより広範囲に揺動できる。   In the above embodiment, the guide shaft 56 is further provided at a position spaced radially outward from the rotation center of the rotating plate 50. The guide shaft 56 moves greatly to the left and right sides with respect to the center of rotation as the rotating plate 50 rotates. The free end portion 72 of the link member 70 swings greatly over a wide range with respect to the base end portion 71. Therefore, since the rotation angle of the base end part 71 and the nozzle support part 60 becomes large, the injection nozzle 91 can swing in a wider range.

上記実施形態では更に、切削液は第一流入管１７を介して噴射装置２１の羽根車収容部２７内に流入する。切削液は第二流入管１８を介してノズル支持部６０内に流入し噴射ノズル９１から噴射する。故に噴射装置２１は噴射ノズル９１から噴射する切削液の勢いを保持できる。   Further, in the above embodiment, the cutting fluid flows into the impeller accommodating portion 27 of the injection device 21 via the first inflow pipe 17. The cutting fluid flows into the nozzle support portion 60 through the second inflow pipe 18 and is sprayed from the spray nozzle 91. Therefore, the spray device 21 can maintain the momentum of the cutting fluid sprayed from the spray nozzle 91.

図１０，図１１を参照し、変形例の噴射装置１２１について説明する。図１０に示す如く、噴射装置１２１は切削液供給管１０の下部に設ける。切削液供給管１０は下部に円形状の設置穴１４を備える。ベアリング１５０は設置穴１４に装着する。   With reference to FIG. 10, FIG. 11, the injection apparatus 121 of a modification is demonstrated. As shown in FIG. 10, the injection device 121 is provided in the lower portion of the cutting fluid supply pipe 10. The cutting fluid supply pipe 10 is provided with a circular installation hole 14 at the bottom. The bearing 150 is installed in the installation hole 14.

噴射装置１２１は羽根部１２２とノズル本体部１２３を備える。羽根部１２２は噴射装置１２１の上側、ノズル本体部１２３は下側に位置する。羽根部１２２は半円形状の４枚の羽根１３１〜１３４を備える。羽根１３１〜１３４は平面視十字の方向に夫々配置する。羽根部１２２は頂点に流入口１３６を備える。羽根部１２２は中心軸に沿って流路１３７を備える。流入口１３６は流路１３７に連通する。なお流入口１３６は頂点に限定せず、位置を変更してもよい。   The injection device 121 includes a blade part 122 and a nozzle body part 123. The blade part 122 is located above the injection device 121 and the nozzle body part 123 is located below. The blade portion 122 includes four semicircular blades 131 to 134. The blades 131 to 134 are arranged in the direction of the cross in plan view. The blade portion 122 includes an inlet 136 at the apex. The wing | blade part 122 is provided with the flow path 137 along the central axis. The inlet 136 communicates with the flow path 137. The inlet 136 is not limited to the apex, and the position may be changed.

ノズル本体部１２３は円柱状である。リング状のベアリング１５０はノズル本体部１２３に当接して回転可能に支持する。故に噴射装置１２１全体は回転可能となる。ノズル本体部１２３は先端側（下部側）に噴射ノズル部１４５を備える。噴射ノズル部１４５は先端側に向けて縮径する。噴射ノズル部１４５は可動式である。噴射ノズル部１４５の先端部は外方に屈曲する。屈曲角度は自由に変更できる。ノズル本体部１２３は内部に流路１４１を備える。流路１４１は噴射ノズル部１４５の先端部を貫通し且つ流路１３７と連通する。   The nozzle body 123 is cylindrical. The ring-shaped bearing 150 abuts on the nozzle main body 123 and supports it rotatably. Therefore, the entire injection device 121 can be rotated. The nozzle body 123 includes an injection nozzle 145 on the tip side (lower side). The injection nozzle portion 145 is reduced in diameter toward the tip side. The injection nozzle unit 145 is movable. The tip of the injection nozzle portion 145 is bent outward. The bending angle can be changed freely. The nozzle main body 123 includes a flow channel 141 inside. The channel 141 passes through the tip of the injection nozzle portion 145 and communicates with the channel 137.

噴射装置１２１の動作について説明する。図１０，図１１に示す如く、切削液は切削液供給管１０を流れる。羽根１３１〜１３４は切削液の流れを受けるので、噴射装置１２１はベアリング１５０を介して回転する。上述の通り、噴射ノズル部１４５は外方に屈曲しているので、回転することによって先端が揺動する。故に噴射装置１２１は切削液を広範囲に噴射できる。噴射ノズル部１４５の屈曲角度を大きくすれば、切削液をより広範囲に噴射できる。本変形例も上記実施形態と同様に電力を消費せずに切削液を噴射する向きを変えることができる。   The operation of the injection device 121 will be described. As shown in FIGS. 10 and 11, the cutting fluid flows through the cutting fluid supply pipe 10. Since the blades 131 to 134 receive the flow of the cutting fluid, the injection device 121 rotates via the bearing 150. As described above, since the injection nozzle portion 145 is bent outward, the tip is swung by rotation. Therefore, the injection device 121 can inject the cutting fluid over a wide range. If the bending angle of the injection nozzle portion 145 is increased, the cutting fluid can be injected over a wider range. In this modified example as well, the direction in which the cutting fluid is sprayed can be changed without consuming electric power, as in the above embodiment.

上記実施形態は、上記変形例以外にも種々の変更が可能である。保護カバー３は左側壁５内面上部に切削液供給管１０を備えるが、他の側壁内面に設けてもよい。切削液供給管１０は略水平方向に配置するが、向きは縦方向でもよく向きは限定しない。   The above embodiment can be variously modified in addition to the above modification. The protective cover 3 includes the cutting fluid supply pipe 10 on the inner surface of the left side wall 5, but may be provided on the inner surface of the other side wall. The cutting fluid supply pipe 10 is arranged in a substantially horizontal direction, but the direction may be a vertical direction and the direction is not limited.

上記実施形態は、羽根車４０を正面視反時計回りに回転するが、羽根車収容部２７における流入穴３０と流出口３２の位置を変えることによって回転方向を逆にしてもよい。   In the above embodiment, the impeller 40 rotates counterclockwise when viewed from the front, but the rotation direction may be reversed by changing the positions of the inlet hole 30 and the outlet port 32 in the impeller accommodating portion 27.

上記実施形態では、ノズル支持部６０をベース部２５の軸支部３７に軸支しているが、ノズル支持部６０をベース部２５の固定板２６に直接軸支する構造であってもよい。   In the above embodiment, the nozzle support portion 60 is pivotally supported by the shaft support portion 37 of the base portion 25, but the nozzle support portion 60 may be directly pivotally supported by the fixing plate 26 of the base portion 25.
