Abstract

In a method for supporting a linear brake, the top plate (31) of the linear brake (30) is mounted to a support body (20) with damper bodies (27, 28) therebetween, the support body (20) being movable on a guide rail (60). A gap for permitting the deformation of the linear brake (30) during clamping is present between the support body (20) and the linear brake (30). A pair of beams (54) are connected to the support body (20) so that the beams (54) are arranged between clamp sections (33) and the guide rail (60) when the support body (20) is disposed on the guide rail (60). The rigidity of the beams (54) in the direction of clamping of the clamping sections (33) is lower than that of the beams (54) in the direction of extension of the guide rail (60).

Description

リニアブレーキの支持方法、リニアブレーキ組付体及びリニアブレーキアダプタLinear brake support method, linear brake assembly and linear brake adapter
　本発明は、リニアブレーキの支持方法、リニアブレーキ組付体及びリニアブレーキアダプタに関するものである。 The present invention relates to a method for supporting a linear brake, a linear brake assembly, and a linear brake adapter.
　工作機械や液晶・半導体製造装置では、ワークを載置するテーブルを高精度かつ高剛性で位置保持する必要がある。それを実現するための部品の一つに、ガイドレールと併用されるリニアブレーキ（特許文献１、特許文献２参照）がある。リニアブレーキは、駆動されるテーブルに取付けられて、任意の位置でガイドレールをクランプすることで、テーブルとガイドレールとの間に弾性的な結合を発生することが可能である。 In machine tools and liquid crystal / semiconductor manufacturing equipment, it is necessary to hold the table on which the workpiece is placed with high accuracy and high rigidity. One of the parts for realizing this is a linear brake (see Patent Document 1 and Patent Document 2) used in combination with a guide rail. The linear brake is attached to the driven table, and can clamp the guide rail at an arbitrary position to generate an elastic coupling between the table and the guide rail.
　テーブルを直線移動させるボールネジを用いた一軸アクチュエータでは、リニアブレーキによるテーブルの駆動軸方向の弾性的な結合の強さ、すなわち位置保持剛性は、一般的に、ボールネジに結合されたサーボモータによる位置保持剛性に比べて高い。そのため、リニアブレーキの使用によって、負荷時の位置ずれや振動が抑制され、これにより加工の高精度化や高速化を実現することができる。 In a single-axis actuator using a ball screw that moves the table linearly, the strength of elastic coupling in the drive axis direction of the table by the linear brake, that is, the position holding rigidity is generally held by a servo motor connected to the ball screw. Higher than rigidity. For this reason, the use of the linear brake suppresses displacement and vibration at the time of loading, thereby realizing high processing accuracy and high speed.

　リニアブレーキの技術的課題として、クランプした瞬間の位置ずれがある。すなわち、リニアブレーキがガイドレールをクランプした瞬間に、テーブルの駆動軸方向と該テーブルに対して垂直な方向とに、それぞれ数μｍの変位が発生することが経験的に知られている。この変位の主な原因は、リニアブレーキを構成する部品の移動や変形、及びリニアブレーキが生じるクランプ力によるテーブルの変形である。 ¡A technical problem with linear brakes is the misalignment at the moment of clamping. That is, it is empirically known that displacement of several μm occurs in the drive axis direction of the table and the direction perpendicular to the table at the moment when the linear brake clamps the guide rail. The main cause of this displacement is the movement and deformation of the parts constituting the linear brake, and the deformation of the table due to the clamping force generated by the linear brake.
　本発明の目的は、クランプ時のリニアブレーキ及びそれを構成する部品の変形や移動によるテーブルの変形や移動を軽減することにある。 An object of the present invention is to reduce the deformation and movement of the table due to the deformation and movement of the linear brake and the parts constituting the linear brake at the time of clamping.
　本発明のリニアブレーキの支持方法において、リニアブレーキは天板と、該天板によって連結された一対の側部と、前記一対の側部内に相互に対向するように設けられた、ガイドレールをクランプするための一対のクランプ部とを有する。前記方法は：前記リニアブレーキの前記天板を、前記ガイドレール上をガイドレールの延出方向に移動可能な支持体に、緩衝体を介して取付ける工程であって、前記支持体と前記リニアブレーキとの間に、クランプ時の前記リニアブレーキの変形を許容する間隙が存在するように取付ける工程と；前記支持体に一対の梁を連結する工程であって、前記一対の梁は、前記支持体が前記ガイドレール上に配置されたときに各梁が各クランプ部と前記ガイドレールとの間に配置されるように連結され、前記一対のクランプ部のクランプ方向における各梁の剛性は、前記ガイドレールの延出方向における各梁の剛性よりも小さい工程とを有する。 In the linear brake support method of the present invention, the linear brake clamps a top plate, a pair of side portions connected by the top plate, and a guide rail provided to face each other in the pair of side portions. And a pair of clamp parts. The method is a step of attaching the top plate of the linear brake to a support body movable on the guide rail in the extending direction of the guide rail via a buffer body, the support body and the linear brake.

　以下、本発明のリニアブレーキの支持方法、リニアブレーキ組付体及びリニアブレーキアダプタの実施形態について、図１～図６を参照して説明する。
　図１、図２に示すように、リニアブレーキ組付体１０は、テーブル２０、リニアブレーキ３０、一対のスライダ４０、及びリニアブレーキアダプタ５０を有する。 Embodiments of a linear brake support method, a linear brake assembly, and a linear brake adapter according to the present invention will be described below with reference to FIGS.
As shown in FIGS. 1 and 2, the linear brake assembly 10 includes a table 20, a linear brake 30, a pair of sliders 40, and a linear brake adapter 50.
　テーブル２０は長手方向を有する平板状であり、該長手方向におけるテーブル２０の両端の下面に、一対のスライダ４０が上面から挿通された複数のボルト２１により、締付け固定されている。テーブル２０は、図示しないボールネジ機構により、一軸方向（後述するガイドレール６０の延出方向）に移動可能となっている。 The table 20 is a flat plate having a longitudinal direction, and a pair of sliders 40 are fastened and fixed to the lower surfaces of both ends of the table 20 in the longitudinal direction by a plurality of bolts 21 inserted from the upper surface. The table 20 is movable in one axial direction (extending direction of a guide rail 60 described later) by a ball screw mechanism (not shown).
　リニアブレーキ組付体１０が乗るガイドレール６０は、頭部６２、底部６４、及びそれらよりも幅の狭い中間部６６を有するＩ形断面を有する。各スライダ４０は、ガイドレール６０のＩ形断面に合致した形状の嵌合溝４２を有しており、該嵌合溝４２がガイドレール６０の頭部６２及び中間部６６に嵌合した状態でガイドレール６０の長手方向に沿って移動自在になっている。 The guide rail 60 on which the linear brake assembly 10 is mounted has an I-shaped cross section having a head portion 62, a bottom portion 64, and an intermediate portion 66 narrower than them. Each slider 40 has a fitting groove 42 having a shape matching the I-shaped cross section of the guide rail 60, and the fitting groove 42 is fitted to the head portion 62 and the intermediate portion 66 of the guide rail 60. The guide rail 60 is movable along the longitudinal direction.
　図４、図５に示すように、テーブル２０の下面の長手方向中央部には、リニアブレーキ３０が取付けられている。
　詳説すると、テーブル２０の上面の長手方向中央部には、段２３付きの取付孔２２が複数個設けられている。取付孔２２は、段２３の上方の大径部２２ａと、段２３の下方に順に配置された中径部２２ｂ、第１小径部２２ｃ、及び第２小径部２２ｄとを有する。中径部２２ｂと第１小径部２２ｃとの間、及び第１小径部２２ｃと第２小径部２２ｄとの間には、それぞれ、第１Ｏリング座２５及び第２Ｏリング座２６が設けられている。 As shown in FIGS. 4 and 5, a linear brake 30 is attached to the central portion in the longitudinal direction of the lower surface of the table 20.
More specifically, a plurality of attachment holes 22 with steps 23 are provided in the longitudinal center of the upper surface of the table 20. The mounting hole 22 includes a large diameter portion 22 a above the step 23, and a medium diameter portion 22 b, a first small diameter portion 22 c, and a second small diameter portion 22 d that are sequentially disposed below the step 23. A first O-ring seat 25 and a second O-ring seat 26 are provided between the middle-diameter portion 22b and the first small-diameter portion 22c and between the first small-diameter portion 22c and the second small-diameter portion 22d, respectively. .
　図２に示すように、リニアブレーキ３０は、天板３１と、天板３１によって連結された一対の側部３２とにより、Ｕ字状に形成されている。天板３１には、テーブル２０の取付孔２２に対応する位置に複数のネジ孔３１ａが穿設されている。 As shown in FIG. 2, the linear brake 30 is formed in a U shape by a top plate 31 and a pair of side portions 32 connected by the top plate 31. A plurality of screw holes 31 a are formed in the top plate 31 at positions corresponding to the mounting holes 22 of the table 20.
　図４、図５に示すように、テーブル２０の取付孔２２には、テーブル２０の上面から取付ボルト２４が挿通され、リニアブレーキ３０のネジ孔３１ａに螺着されている。また、第１Ｏリング座２５及び第２Ｏリング座２６にはＯリング２７、２８が配置されている。 4 and 5, the mounting bolts 24 are inserted into the mounting holes 22 of the table 20 from the upper surface of the table 20 and screwed into the screw holes 31 a of the linear brake 30. Further, O- rings 27 and 28 are arranged on the first O-ring seat 25 and the second O-ring seat 26.
　取付ボルト２４の頭部は、段２３に接触しないようにＯリング２７に係止される。さらに、取付ボルト２４の頭部は大径部２２ａの内周面に接触しないように、大径部２２ａよりも小径となっている。図５に示すように、テーブル２０の下面とリニアブレーキ３０の上面とは、互いに接触しないように第２Ｏリング２８によって距離Ｌだけ離間されている。 The head of the mounting bolt 24 is locked to the O-ring 27 so as not to contact the step 23. Furthermore, the head of the mounting bolt 24 has a smaller diameter than the large diameter portion 22a so as not to contact the inner peripheral surface of the large diameter portion 22a. As shown in FIG. 5, the lower surface of the table 20 and the upper surface of the linear brake 30 are separated by a distance L by the second O-ring 28 so as not to contact each other.
　この離間距離Ｌは、後述するリニアブレーキ３０のクランプ部３３がガイドレール６０等をクランプしたときの反力に起因するリニアブレーキ３０の両側部３２の反り上がりが、テーブル２０の下面によって干渉されないような距離、すなわち、リニアブレーキ３０の変形を許容する距離に設定されている。 The separation distance L is set so that the warping of both side portions 32 of the linear brake 30 caused by the reaction force when the clamp portion 33 of the linear brake 30 described later clamps the guide rail 60 or the like is not interfered by the lower surface of the table 20. This distance is set to a distance that allows the linear brake 30 to be deformed.
　上記のようにして、リニアブレーキ３０とテーブル２０との間にＯリング２７、２８を緩衝体として介在させることにより、リニアブレーキ３０は支持体としてのテーブル２０から弾性的に吊下げられている。 As described above, the O- rings 27 and 28 are interposed as a buffer between the linear brake 30 and the table 20, so that the linear brake 30 is elastically suspended from the table 20 as a support.
　図５に示すように、リニアブレーキ３０の各側部３２にはクランプ部３３が設けられている。
　クランプ部３３は、公知の空圧式、油圧式、或いは、モータ等により回転されるカム式等のいずれでもよく、また、ノーマルオープンタイプ、ノーマルクローズタイプのいずれでもよい。本実施形態のクランプ部３３は、空圧式のノーマルオープンタイプである。 As shown in FIG. 5, a clamp portion 33 is provided on each side portion 32 of the linear brake 30.
The clamp portion 33 may be any of a known pneumatic type, hydraulic type, cam type rotated by a motor, or the like, and may be either a normal open type or a normal close type. The clamp part 33 of this embodiment is a pneumatic-type normally open type.
　図５に示すように、各クランプ部３３は、互いに対向する位置にブレーキシュー３４を備えている。各クランプ部３３がクランプ方向に作動すると、側部３２からのブレーキシュー３４の突出量が増大して、両側部３２間にあるガイドレール６０の頭部６２を、後述するリニアブレーキアダプタ５０の梁５４を介してクランプする。 As shown in FIG. 5, each clamp part 33 is equipped with the brake shoe 34 in the position which mutually opposes. When each clamp part 33 is operated in the clamping direction, the amount of protrusion of the brake shoe 34 from the side part 32 increases, and the head 62 of the guide rail 60 between the side parts 32 moves to the beam of the linear brake adapter 50 described later. Clamp through 54.
　図２、図３に示すように、リニアブレーキアダプタ５０は、一対の取付体５１と、両取付体５１間に平行に延びて両取付体５１を連結する一対の梁５４とを有する。取付体５１は立方体の形状を有し、下部には、ガイドレール６０の頭部６２の幅よりも広い幅を有する嵌合溝５２が形成されている。図６に示すように、取付体５１は、上面に複数のネジ孔５３を有する。テーブル２０の上面から挿通された取付ボルト２９がネジ孔５３に螺着されることにより、取付体５１はテーブル２０に取付け固定されている。嵌合溝５２は、ガイドレール６０の頭部６２に遊びを以て嵌合している。 2 and 3, the linear brake adapter 50 includes a pair of attachment bodies 51 and a pair of beams 54 that extend in parallel between the attachment bodies 51 and connect the attachment bodies 51. The attachment body 51 has a cubic shape, and a fitting groove 52 having a width wider than the width of the head 62 of the guide rail 60 is formed in the lower part. As shown in FIG. 6, the attachment body 51 has a plurality of screw holes 53 on the upper surface. The mounting body 51 is fixedly attached to the table 20 by screwing the mounting bolts 29 inserted from the upper surface of the table 20 into the screw holes 53. The fitting groove 52 is fitted to the head 62 of the guide rail 60 with play.
　両梁５４の離間距離は、ガイドレール６０の頭部６２の幅よりも若干長い。そして、図５に示すように、各梁５４は、各ブレーキシュー３４とガイドレール６０の頭部６２との間に配置されている。 The separation distance between both beams 54 is slightly longer than the width of the head 62 of the guide rail 60. As shown in FIG. 5, each beam 54 is disposed between each brake shoe 34 and the head 62 of the guide rail 60.
　クランプ部３３のクランプ方向における各梁５４の剛性は、ガイドレール６０の延出方向における各梁５４の剛性よりも小さい。ここで、ガイドレール６０の延出方向は、各梁５４の延出方向と同じであり、クランプ部３３のクランプ方向は、一対の梁５４の対向方向と同じである。すなわち、各梁５４の延出方向における剛性は、該延出方向と直交する一対の梁５４の対向方向における剛性よりも大きい。また、各梁５４の外面のブレーキシュー３４と対向する位置に突部５４ｂが形成され、突部５４ｂの反対側の各梁５４の内面には、突部５４ａが形成されている。 The rigidity of each beam 54 in the clamping direction of the clamp part 33 is smaller than the rigidity of each beam 54 in the extending direction of the guide rail 60. Here, the extending direction of the guide rail 60 is the same as the extending direction of each beam 54, and the clamping direction of the clamp part 33 is the same as the facing direction of the pair of beams 54. That is, the rigidity in the extending direction of each beam 54 is greater than the rigidity in the facing direction of the pair of beams 54 orthogonal to the extending direction. Further, a protrusion 54b is formed at a position facing the brake shoe 34 on the outer surface of each beam 54, and a protrusion 54a is formed on the inner surface of each beam 54 opposite to the protrusion 54b.
　一対の梁５４は、ガイドレール６０の延出方向（図５では紙面と直交する方向）に延びる中心軸Ｏを含む仮想鉛直面Ｅ（図５では上下方向に延びる仮想平面）に対して面対称の形状であることが好ましい。また、一対の梁５４は、上記仮想鉛直面Ｅに対して面対称に配置されていることが好ましい。 The pair of beams 54 are plane-symmetric with respect to a virtual vertical plane E (a virtual plane extending in the vertical direction in FIG. 5) including a central axis O extending in the extending direction of the guide rail 60 (a direction orthogonal to the paper surface in FIG. 5). It is preferable that it is the shape of this. In addition, the pair of beams 54 is preferably arranged in plane symmetry with respect to the virtual vertical plane E.
　各梁５４の延出方向における中間部を挟んだ両側は、該中間部を通りかつ上記仮想鉛直面Ｅと直交する仮想平面に対して面対称の形状であることが好ましく、かつ、上記仮想平面に対して面対称に配置されていることが好ましい。上記のように各梁５４が形成され配置されていることにより、一対の梁５４同士の剛性の良好なバランスが得られる。 It is preferable that both sides of the intermediate portion in the extending direction of each beam 54 have a symmetrical shape with respect to a virtual plane passing through the intermediate portion and orthogonal to the virtual vertical plane E, and the virtual plane It is preferable to arrange | position symmetrically with respect to. Since each beam 54 is formed and arranged as described above, a good balance of rigidity between the pair of beams 54 can be obtained.
　クランプ部３３がクランプ方向に作動していないときは、梁５４の突部５４ａはガイドレール６０の頭部６２から離間しており、かつ突部５４ｂはブレーキシュー３４に常時当接している。クランプ部３３がクランプ方向に作動した際には、梁５４の突部５４ｂがブレーキシュー３４によりクランプ方向に押圧されて、突部５４ａがガイドレール６０の頭部６２をクランプする。 When the clamp portion 33 is not operating in the clamping direction, the projection 54a of the beam 54 is separated from the head 62 of the guide rail 60, and the projection 54b is always in contact with the brake shoe 34. When the clamp portion 33 operates in the clamping direction, the projection 54 b of the beam 54 is pressed in the clamping direction by the brake shoe 34, and the projection 54 a clamps the head 62 of the guide rail 60.
　（実施形態の作用）
　上記実施形態の作用について説明する。
　本実施形態では、図示しないボールネジ機構により、テーブル２０がガイドレール６０の延出方向に移動中は、リニアブレーキ３０はアンクランプ状態である。テーブル２０が停止した後に、リニアブレーキ３０の両クランプ部３３がクランプ動作する。図５に示すように、両クランプ部３３が作動すると、各ブレーキシュー３４が、各梁５４の突部５４ｂをクランプ方向に押圧するため、突部５４ａがガイドレール６０の頭部６２をクランプする。 (Operation of the embodiment)
The operation of the above embodiment will be described.
In the present embodiment, the linear brake 30 is in an unclamped state while the table 20 is moving in the extending direction of the guide rail 60 by a ball screw mechanism (not shown). After the table 20 is stopped, both the clamp portions 33 of the linear brake 30 are clamped. As shown in FIG. 5, when both the clamp portions 33 are operated, each brake shoe 34 presses the projection 54 b of each beam 54 in the clamping direction, so that the projection 54 a clamps the head 62 of the guide rail 60. .
　リニアブレーキ３０のクランプ部３３が、梁５４を介してガイドレール６０をクランプしたときの反力により、リニアブレーキ３０の両側部３２が上方へ反る。テーブル２０の下面と両側部３２の上面との間に離間距離Ｌが存在するため、この両側部３２の反り上がりがテーブル２０の下面によって干渉されることはない。 The both side portions 32 of the linear brake 30 warp upward by the reaction force when the clamp portion 33 of the linear brake 30 clamps the guide rail 60 via the beam 54. Since there is a separation distance L between the lower surface of the table 20 and the upper surfaces of the both side portions 32, the warping of the both side portions 32 is not interfered by the lower surface of the table 20.
　また、リニアブレーキ３０が緩衝体であるＯリング２７、２８を介してテーブル２０に支持されているため、リニアブレーキ３０のテーブル２０による拘束力は、テーブル２０との直接接触を介して支持されている場合に比して小さい。このため、リニアブレーキ３０はテーブル２０に対しては、Ｏリング２７、２８が許容する範囲で移動してクランプを完了する。この移動には、テーブル２０の一軸移動方向（ガイドレール６０の延出方向）の移動も含まれる。 Further, since the linear brake 30 is supported by the table 20 via the O- rings 27 and 28 which are buffer bodies, the restraining force of the linear brake 30 by the table 20 is supported through direct contact with the table 20. Smaller than the case. Therefore, the linear brake 30 moves relative to the table 20 within the range allowed by the O- rings 27 and 28 to complete the clamping. This movement includes movement in the uniaxial movement direction of the table 20 (extension direction of the guide rail 60).
　緩衝体（本実施形態ではＯリング２７、２８）を介したことによるテーブル２０の一軸移動方向（ガイドレール６０の延出方向）の剛性の低下は、ガイドレール６０とリニアブレーキ３０との間に配置されている梁５４によって補われる。すなわち、梁５４は、テーブル２０の一軸移動方向において大きな剛性を有しているため、前述のテーブル２０の一軸移動方向の剛性の低下を補う。また、クランプ部３３のクランプ方向における梁５４の剛性はガイドレール６０の延出方向における剛性よりも小さいため、梁５４はクランプ方向（クランプ力が作用する方向）に容易に変形する。 The reduction in rigidity in the uniaxial movement direction of the table 20 (the direction in which the guide rail 60 extends) due to the buffer (in this embodiment, the O-rings 27 and 28) is caused between the guide rail 60 and the linear brake 30. It is supplemented by the arranged beam 54. That is, since the beam 54 has a large rigidity in the uniaxial movement direction of the table 20, the above-described decrease in the rigidity of the table 20 in the uniaxial movement direction is compensated. Further, since the rigidity of the beam 54 in the clamping direction of the clamp portion 33 is smaller than the rigidity in the extending direction of the guide rail 60, the beam 54 is easily deformed in the clamping direction (direction in which the clamping force acts).
　この結果、梁５４を介してガイドレール６０をクランプ部３３にてクランプすることにより、リニアブレーキ及びそれを構成する部品の変形や移動によるテーブルの変形や移動を軽減でき、また、テーブルの位置保持剛性を高くすることができる。 As a result, the guide rail 60 is clamped by the clamp portion 33 via the beam 54, so that the deformation and movement of the table due to the deformation and movement of the linear brake and the components constituting the linear brake can be reduced, and the position of the table can be maintained. The rigidity can be increased.
　さらに、梁５４を介してクランプ部３３がガイドレール６０をクランプした時に、緩衝体を介してテーブル２０に伝わる力は、緩衝体であるＯリング２７、２８の形状及び材質によって調整することができる。この調整によって、クランプ部３３がガイドレール６０をクランプしたときの一軸方向の移動をさらに抑制することができる。 Further, when the clamp portion 33 clamps the guide rail 60 via the beam 54, the force transmitted to the table 20 via the buffer body can be adjusted by the shape and material of the O- rings 27 and 28 that are buffer bodies. . By this adjustment, the movement in the uniaxial direction when the clamp portion 33 clamps the guide rail 60 can be further suppressed.
　本実施形態から把握できる本発明の特徴及びその効果を以下に記載する。
　（１）本発明のリニアブレーキの支持方法では、ガイドレール６０上をガイドレール６０の延出方向に移動可能な支持体２０に、リニアブレーキ３０の天板３１が、緩衝体２７、２８を介して取付けられる。支持体２０とリニアブレーキ３０との間には、クランプ時のリニアブレーキ３０の変形を許容する間隙が存在する。また、支持体２０には一対の梁５４が連結される。一対の梁５４は、支持体２０がガイドレール６０上に配置されたときに各梁５４が各クランプ部３３とガイドレール６０との間に配置されるように連結される。クランプ部３３のクランプ方向における各梁５４の剛性は、ガイドレール６０の延出方向における各梁５４の剛性よりも小さい。 The features and effects of the present invention that can be understood from the present embodiment will be described below.
(1) In the linear brake support method of the present invention, the top plate 31 of the linear brake 30 is interposed via the buffer bodies 27 and 28 on the support body 20 movable on the guide rail 60 in the extending direction of the guide rail 60. Installed. There is a gap between the support 20 and the linear brake 30 that allows deformation of the linear brake 30 during clamping. A pair of beams 54 are connected to the support 20. The pair of beams 54 are connected such that each beam 54 is disposed between each clamp portion 33 and the guide rail 60 when the support 20 is disposed on the guide rail 60. The rigidity of each beam 54 in the clamping direction of the clamp portion 33 is smaller than the rigidity of each beam 54 in the extending direction of the guide rail 60.
　この方法によれば、クランプ時のリニアブレーキ及びそれを構成する部品の変形や移動によるテーブルの変形や移動を軽減できる。
　（２）本発明のリニアブレーキ組付体１０は、天板３１と、天板３１によって連結された一対の側部３２と、一対の側部３２内に相互に対向するように設けられた、ガイドレール６０をクランプするための一対のクランプ部３３とを有するリニアブレーキ３０と、リニアブレーキ３０の天板３１を緩衝体２７、２８を介して支持する支持体２０であって、ガイドレール６０上をガイドレール６０の延出方向に移動可能な支持体２０と、支持体２０に連結され、リニアブレーキ３０の一対の側部３２の間に平行に延びる一対の梁５４とを有する。支持体２０とリニアブレーキ３０との間には、一対のクランプ部３３によるガイドレール６０のクランプ時のリニアブレーキ３０の変形を許容する間隙が存在する。一対の梁５４は、一対のクランプ部３３がガイドレール６０をクランプする際に、ガイドレール６０と各クランプ部３３との間に各梁５４が挟み込まれるように配置されている。クランプ部３３のクランプ方向における各梁５４の剛性は、クランプ方向と直交するガイドレール６０の延出方向における各梁５４の剛性よりも小さい。 According to this method, it is possible to reduce the deformation and movement of the table due to the deformation and movement of the linear brake and the parts constituting the linear brake at the time of clamping.
(2) The linear brake assembly 10 of the present invention is provided so as to face each other in the top plate 31, the pair of side portions 32 connected by the top plate 31, and the pair of side portions 32. A linear brake 30 having a pair of clamp portions 33 for clamping the guide rail 60, and a support body 20 that supports the top plate 31 of the linear brake 30 via buffer bodies 27, 28, The support 20 is movable in the extending direction of the guide rail 60, and the pair of beams 54 connected to the support 20 and extending in parallel between the pair of side portions 32 of the linear brake 30. Between the support 20 and the linear brake 30, there is a gap that allows deformation of the linear brake 30 when the guide rail 60 is clamped by the pair of clamp portions 33. The pair of beams 54 are arranged such that each beam 54 is sandwiched between the guide rail 60 and each clamp portion 33 when the pair of clamp portions 33 clamp the guide rail 60. The rigidity of each beam 54 in the clamping direction of the clamp part 33 is smaller than the rigidity of each beam 54 in the extending direction of the guide rail 60 orthogonal to the clamping direction.
　このリニアブレーキ組付体１０は、上記リニアブレーキの支持方法に直接使用することができ、したがって上記方法の効果を得ることができる。
　（３）上記リニアブレーキ組付体１０は、一対の梁５４によって連結されているとともに支持体２０に固定された一対の取付体５１をさらに備えることが好ましい。この構成によれば、リニアブレーキ組付体１０の製造時に、一対の取付体５１を支持体２０に取付けることにより、一対の梁５４を同時に配置することができる。 The linear brake assembly 10 can be used directly in the method of supporting the linear brake, and therefore the effect of the method can be obtained.
(3) It is preferable that the linear brake assembly 10 further includes a pair of attachment bodies 51 that are connected to each other by a pair of beams 54 and fixed to the support body 20. According to this configuration, the pair of beams 54 can be simultaneously disposed by attaching the pair of attachment bodies 51 to the support body 20 when the linear brake assembly 10 is manufactured.
