以下、本発明に係る制動制御機構の実施形態について、図面を参照しながら説明する。
はじめに、本発明に係る制動制御機構が適用されるリニアモータ方式の直動案内装置の装置構成について説明する。
図２は図３中Ａ−Ａで示す断面におけるリニアモータ方式の直動案内装置の要部平断面図、図３はリニアモータ方式の直動案内装置の要部側面図、図４は図２中Ｂ部を拡大した押圧機構の断面図である。 Hereinafter, an embodiment of a braking control mechanism according to the present invention will be described with reference to the drawings.
First, a device configuration of a linear motor type linear motion guide device to which a braking control mechanism according to the present invention is applied will be described.
2 is a cross-sectional plan view of the main part of the linear motor type linear motion guide apparatus in the cross section indicated by AA in FIG. 3, FIG. 3 is a side view of the main part of the linear motor type linear motion guide apparatus, and FIG. It is sectional drawing of the press mechanism which expanded the middle B part.

図２及び図３に示すように、工作機械等の産業機械におけるリニアモータ方式の直動案内装置は、機械の固定側である案内レール１０に沿って送りテーブル等の移動体１１がギブ１２と押圧機構１３を介して移動可能になっている。図示例では、移動体１１の凹部１１ａが案内レール１０の角ガイド部１０ａに下方から嵌合されて直動案内部が形成されている。このように、本発明に係る制動制御機構が適用されるリニアモータ方式の直動案内装置においては、移動体１１はリニアモータにより駆動されている。   As shown in FIGS. 2 and 3, a linear motor type linear motion guide device in an industrial machine such as a machine tool has a moving body 11 such as a feed table along a guide rail 10 which is a fixed side of the machine. It is movable via the pressing mechanism 13. In the illustrated example, the concave portion 11a of the moving body 11 is fitted to the corner guide portion 10a of the guide rail 10 from below to form a linear motion guide portion. Thus, in the linear motor type linear motion guide apparatus to which the braking control mechanism according to the present invention is applied, the moving body 11 is driven by the linear motor.

ギブ１２は、移動体１１の移動方向に押引きすることで、案内レール１０（厳密には角ガイド部１０ａ）の一方摺動面と移動体１１（厳密には凹部１１ａ）の摺動面との間の隙間（図２及び図３中のＤ部参照）を調整する周知のものであるが、本実施形態では、後述する押圧機構１３により案内レール１０（厳密には角ガイド部１０ａ）の他方摺動面に押し付けられ、図２及び図３中のＤ部において案内レール１０（厳密には角ガイド部１０ａ）の一方摺動面と移動体１１（厳密には凹部１１ａ）の摺動面とが密接されている。   The give 12 is pushed and pulled in the moving direction of the moving body 11, so that one sliding surface of the guide rail 10 (strictly, the corner guide portion 10a) and the sliding surface of the moving body 11 (strictly, the concave portion 11a) In this embodiment, the guide rail 10 (strictly, the corner guide portion 10a) is moved by a pressing mechanism 13 described later. The sliding surface of the guide rail 10 (strictly, the corner guide portion 10a) and the sliding surface of the movable body 11 (strictly, the recess 11a) are pressed against the other sliding surface and in the portion D in FIGS. And have been closely.

押圧機構１３は、図４にも示すように、移動体１１の凹部１１ａに形成された貫通孔１４に往復移動可能に収装され、その先端部がギブ１２の摺動面と反対側の面（押圧面）に押し当てられるピストン１５と、このピストン１５の背部に位置する貫通孔１４内に、配管継手１６を介して、後述する本発明に係る制動制御機構（図１参照）と接続される。   As shown also in FIG. 4, the pressing mechanism 13 is accommodated in a through hole 14 formed in the concave portion 11 a of the moving body 11 so as to be able to reciprocate, and a tip portion thereof is a surface opposite to the sliding surface of the give 12. A piston 15 pressed against the (pressing surface) and a through-hole 14 located at the back of the piston 15 are connected to a braking control mechanism (see FIG. 1) according to the present invention, which will be described later, via a pipe joint 16. The

図示例では、ギブ１２の押圧面に半球状の凹部１２ａが形成され、この凹部１２ａにピストン１５の先端部に形成した半球状の凸部１５ａを嵌合させている。なお、ピストン１５の外周面にはＯリング１７が装着されている。また、ギブ１２の押圧面には、その移動方向に所定間隔離間した複数箇所にてピストン１５が押し当てられている。
以上が本発明に係る制動制御機構が適用されるリニアモータ方式の直動案内装置の装置構成である。 In the illustrated example, a hemispherical concave portion 12 a is formed on the pressing surface of the give 12, and a hemispherical convex portion 15 a formed at the tip of the piston 15 is fitted into the concave portion 12 a. An O-ring 17 is attached to the outer peripheral surface of the piston 15. Further, the piston 15 is pressed against the pressing surface of the give 12 at a plurality of positions spaced apart by a predetermined distance in the moving direction.
The above is the apparatus configuration of the linear motor type linear motion guide apparatus to which the braking control mechanism according to the present invention is applied.

次に、本発明に係る本発明に係る制動制御機構の構成について説明する。
図１は本発明に係る制動制御機構の構成図である。なお、図１中においては、エアー源１側を上流として説明する。
図１に示すように、本発明に係る制動制御機構は、エアー源１に空気の逆流を防ぐチェック弁２を介して空気を貯えるエアータンク３が設置されている。エアータンク３の下流にはエアータンク３から流れ出る空気の圧力を調整する第１のレギュレータ４が設置されている。第１のレギュレータ４の下流には、空気圧を入力することにより油圧を出力することができるエアー・ハイドロ・ブースター５が設置されている。 Next, the configuration of the braking control mechanism according to the present invention according to the present invention will be described.
FIG. 1 is a block diagram of a braking control mechanism according to the present invention. In FIG. 1, the air source 1 side will be described as upstream.
As shown in FIG. 1, in the braking control mechanism according to the present invention, an air tank 3 for storing air is installed in an air source 1 via a check valve 2 that prevents backflow of air. A first regulator 4 for adjusting the pressure of the air flowing out from the air tank 3 is installed downstream of the air tank 3. An air hydro booster 5 that can output hydraulic pressure by inputting air pressure is installed downstream of the first regulator 4.

エアー・ハイドロ・ブースター５の下流は、ピストン１５によりギブ１２が案内レール１０に押し付けられ、移動体１１と案内レール１０が密着する程度の圧力である摺動時の油圧を伝達する摺動油圧経路と、ピストン１５によりギブ１２が案内レール１０に押し付けられて、移動体１１の運動を制動する程度の圧力である制動時の油圧を伝達する制動油圧経路とに分かれている。摺動油圧経路側のエアー・ハイドロ・ブースター５の下流には、エアー・ハイドロ・ブースター５から流れ出る油の圧力を調整する第２のレギュレータ６が設置されている。   Downstream of the air-hydro booster 5, a sliding hydraulic path that transmits a hydraulic pressure at the time of sliding, which is a pressure at which the moving body 11 and the guide rail 10 are in close contact with each other when the give 12 is pressed against the guide rail 10 by the piston 15. And the giver 12 is pressed against the guide rail 10 by the piston 15 and is divided into a braking hydraulic pressure path for transmitting a hydraulic pressure at the time of braking, which is a pressure to brake the movement of the moving body 11. A second regulator 6 that adjusts the pressure of oil flowing out of the air-hydro booster 5 is installed downstream of the air-hydro booster 5 on the sliding hydraulic path side.

第２のレギュレータ６の下流にはソレノイドバルブ７が設置されている。なお、第２のレギュレータ６により調整される圧力は、第１のレギュレータ４により調整される圧力よりも低い圧力であり、ピストン１５によりギブ１２が案内レール１０に押し付けられ、移動体１１と案内レール１０が密着する程度の圧力である。   A solenoid valve 7 is installed downstream of the second regulator 6. The pressure adjusted by the second regulator 6 is lower than the pressure adjusted by the first regulator 4, and the give 12 is pressed against the guide rail 10 by the piston 15, so that the moving body 11 and the guide rail are The pressure is such that 10 is in close contact.

また、制動油圧経路側のエアー・ハイドロ・ブースター５の下流にはソレノイドバルブ７が設置されている。そして、ソレノイドバルブ７の下流には、配管継手１６（図２参照）が接続されている。   A solenoid valve 7 is installed downstream of the air / hydro booster 5 on the brake hydraulic pressure path side. A piping joint 16 (see FIG. 2) is connected downstream of the solenoid valve 7.

ソレノイドバルブ７は、ソレノイドバルブ７に電力が供給されているときには摺動油圧経路側を配管継手１６と接続し、ソレノイドバルブ７への電力の供給が断たれたときには制動油圧経路側を配管継手１６と接続する。このため、ピストン１５には、ソレノイドバルブ７に電力が供給されているときには第２のレギュレータ６で調整した油圧が加わり、ソレノイドバルブ７への電力の供給が断たれたときには第１のレギュレータ４で調整した油圧が加わるようになっている。なお、図１においては、ソレノイドバルブ７は制動油圧経路側を配管継手１６と接続している様子を示している。   The solenoid valve 7 connects the sliding hydraulic path side to the piping joint 16 when power is supplied to the solenoid valve 7, and the braking hydraulic path side is connected to the piping joint 16 when power supply to the solenoid valve 7 is cut off. Connect with. Therefore, the hydraulic pressure adjusted by the second regulator 6 is applied to the piston 15 when power is supplied to the solenoid valve 7, and when the power supply to the solenoid valve 7 is cut off, the first regulator 4 is used. Adjusted hydraulic pressure is applied. In FIG. 1, the solenoid valve 7 shows a state in which the brake hydraulic pressure path side is connected to the pipe joint 16.

これにより、本発明に係る制動制御機構は、リニアモータへ電力が供給されると同時に、ソレノイドバルブ７が励磁され、摺動用に設定された油圧がピストン１５に供給される。そして、押圧機構１３により、ギブ１２が案内レール１０（厳密には角ガイド部１０ａ）の他方摺動面に押し付けられるので、案内レール１０（厳密には角ガイド部１０ａ）の一方摺動面と移動体１１（厳密には凹部１１ａ）の摺動面とが密接された状態で移動体１１が移動可能となり、機械精度を向上させることができる。   Thus, in the braking control mechanism according to the present invention, power is supplied to the linear motor, and at the same time, the solenoid valve 7 is excited and the hydraulic pressure set for sliding is supplied to the piston 15. Since the giving mechanism 13 is pressed against the other sliding surface of the guide rail 10 (strictly, the corner guide portion 10a) by the pressing mechanism 13, the one sliding surface of the guide rail 10 (strictly, the corner guide portion 10a) The moving body 11 can be moved in a state where the sliding surface of the moving body 11 (strictly, the recess 11a) is in close contact, and the mechanical accuracy can be improved.

また、滑りにより移動体１１（厳密には凹部１１ａ）の摺動面が摩耗しても、ギブ１２により常にかつ自動的に、案内レール１０（厳密には角ガイド部１０ａ）の一方摺動面と移動体１１（厳密には凹部１１ａ）の摺動面との密接状態が保持されるので、機械精度の長期安定化を図ることができる。加えて、摺動隙間が自動的に管理されるので、作業者等の負担を軽減することができる。   Further, even if the sliding surface of the moving body 11 (strictly, the recess 11a) is worn by sliding, the one sliding surface of the guide rail 10 (strictly, the corner guide portion 10a) is always and automatically provided by the give 12. Since the close contact state between the movable body 11 and the sliding surface of the movable body 11 (strictly, the concave portion 11a) is maintained, the mechanical accuracy can be stabilized for a long period of time. In addition, since the sliding gap is automatically managed, the burden on the operator or the like can be reduced.

また、本発明に係る制動制御機構は、工作機械の電源を落とすなどリニアモータへの電力の供給が断たれるとソレノイドバルブ７の励磁も断たれ、配管継手１６に接続される。このとき、エアー源１への電力の供給が断たれ空気の供給が断たれた場合であっても、エアータンク３に貯えられた空気によりピストン１５に油圧を供給することができる。また、第１のレギュレータ４により調整される圧力は、ピストン１５によりギブ１２が案内レール１０に押し付けられて、移動体１１の運動を制動する程度の圧力である。   Further, the brake control mechanism according to the present invention is connected to the pipe joint 16 when the power supply to the linear motor is cut off, such as when the power to the linear motor is cut off, and the solenoid valve 7 is also turned off. At this time, even if the supply of electric power to the air source 1 is cut off and the supply of air is cut off, the hydraulic pressure can be supplied to the piston 15 by the air stored in the air tank 3. Further, the pressure adjusted by the first regulator 4 is a pressure at which the give 12 is pressed against the guide rail 10 by the piston 15 and brakes the movement of the moving body 11.

これにより、制動用に設定された高圧の油圧がピストン１５に供給される。そして、押圧機構１３により、ギブ１２が案内レール１０（厳密には角ガイド部１０ａ）の他方摺動面に強く押し付けられるので、摺動抵抗が急上昇して、移動体の運動を制動することができる。   As a result, the high pressure hydraulic pressure set for braking is supplied to the piston 15. And since the give 12 is strongly pressed by the pressing mechanism 13 against the other sliding surface of the guide rail 10 (strictly, the corner guide portion 10a), the sliding resistance rapidly increases, and the movement of the moving body can be braked. it can.

なお、本実施形態に係る制動制御機構においては、空気圧と油圧とを用いているが、油圧のみを用いて制動制御機構を構成すること、又は、空気圧のみを用いて制動制御機構を構成することも可能である。   In the brake control mechanism according to the present embodiment, air pressure and hydraulic pressure are used. However, the brake control mechanism is configured using only the hydraulic pressure, or the brake control mechanism is configured using only the air pressure. Is also possible.

以上説明したように、本発明に係る制動制御機構によれば、リニアモータにより駆動されて案内レール１０上を移動する移動体１１と、移動体１１を案内レール１０に押圧する押圧機構１３からなる押圧手段と、押圧手段を油圧により駆動するエアー源１や第１のレギュレータ４等からなる油圧手段と、リニアモータへの電力の供給が断たれたときに油圧手段と押圧手段とを接続し油圧を押圧手段へ伝達させるソレノイドバルブ７からなる制御弁とを備えることにより、リニアモータへの電力の供給が断たれたときには、移動体１１の運動を制動することができる。   As described above, the braking control mechanism according to the present invention includes the moving body 11 that is driven by the linear motor and moves on the guide rail 10, and the pressing mechanism 13 that presses the moving body 11 against the guide rail 10. The hydraulic means including the pressing means, the air source 1 that drives the pressing means by hydraulic pressure, the first regulator 4 and the like, and the hydraulic means and the pressing means are connected when the power supply to the linear motor is cut off. By providing the control valve including the solenoid valve 7 that transmits the pressure to the pressing means, the movement of the moving body 11 can be braked when the supply of power to the linear motor is cut off.

また、空気圧を油圧に変換するエアー・ハイドロ・ブースター５からなる変換手段と、空気を貯えるエアータンク３からなる空気貯蔵手段とを備えることにより、エアー源１への電力の供給が断たれ空気の供給が断たれた場合であっても、エアータンク３に貯えられた空気によりピストン１５に油圧を供給することができる。   Further, by providing a conversion means comprising an air-hydro booster 5 for converting air pressure to hydraulic pressure and an air storage means comprising an air tank 3 for storing air, the supply of electric power to the air source 1 is cut off and the air Even if the supply is cut off, the hydraulic pressure can be supplied to the piston 15 by the air stored in the air tank 3.

また、押圧手段を油圧手段よりも低圧の油圧により駆動するエアー源１や第２のレギュレータ６からなる低圧油圧手段を備え、制御弁は、リニアモータへの電力の供給がなされているときに低圧油圧手段と押圧手段とを接続し低圧油圧を押圧手段へ伝達させることにより、リニアモータへの電力の供給がなされているときには、案内レール１０の一方摺動面と移動体１１の摺動面とが密接された状態で移動体１１が移動可能となり、機械精度を向上させることができる。   In addition, low pressure hydraulic means including an air source 1 and a second regulator 6 that drive the pressing means with hydraulic pressure lower than that of the hydraulic means is provided, and the control valve is low when electric power is supplied to the linear motor. When power is supplied to the linear motor by connecting the hydraulic means and the pressing means and transmitting the low pressure hydraulic pressure to the pressing means, the one sliding surface of the guide rail 10 and the sliding surface of the moving body 11 The movable body 11 can be moved in a state where the two are in close contact with each other, and the mechanical accuracy can be improved.

したがって、本願発明によれば、既存の設備を利用することで、簡易な構造により、リニアモータへの電源供給停止時の移動体１１の運動を制動することができる制動制御機構を提供することができる。   Therefore, according to the invention of the present application, it is possible to provide a braking control mechanism that can brake the movement of the moving body 11 when the power supply to the linear motor is stopped with a simple structure by using existing equipment. it can.

本発明は、例えば、リニアモータ方式の直動案内装置における制動制御機構として利用することが可能である。   The present invention can be used, for example, as a braking control mechanism in a linear motor type linear motion guide device.
