This will be described with reference to the drawings.
FIG. 1 is an axial cross-sectional view along the axis of the guide rail of the present invention.
2 is a cross-sectional view taken along the line AB of FIG.
In FIG. 1, a guide table 8 that is guided by the guide rail 1 and slides, and a housing 2 that is moved by the guide rail 1 are connected by a connection plate 9 and a connection pin 7, in the direction of the connection pin 7. The relationship is clearly movable.
Next, referring to FIGS. 1 and 2, the structure and operation of the brake device of the present invention will be described. The inclined surfaces formed on the housing 2 are engraved on both inclined side surfaces 11 and 12 of the guide rail 1. Inside the housing 2 are a brake member 3, a force-increasing wedge 5 via four cylindrical rollers 4 as a force-increasing mechanism for pressing the brake member 3 against the facing surface 13 of the guide rail mounting surface, and a cylindrical roller 4. A mating member is incorporated, and a spring 6 and a release piston 10 for operating the booster wedge 5 are incorporated in the housing 2.
When exhausted from the air supply / exhaust port 14, the increasing wedge 5 is pulled in the axial direction by the spring force of the spring 6, and the brake member 3 is pressed against the surface 13 of the guide rail 1 and at the same time the inclined surfaces 11, 12 of the guide rail 1. Lift up the housing 2 at once.
At this time, the contact pressure against the guide rail 1 causes a frictional force for braking or locking.

［実施例］
ガイドテーブル８は鋼球を使用したころがりガイドであり、レール幅は２５ｍｍにおいて下記の条件で実施した結果を記す。
ハウヂング２及びブレーキ部材３の材質、ダクタイル鋳鉄。
円筒ころ４の外径、５ｍｍ。増力くさび５のくさび角、３．０度。スプリング６のスプリング力、３３０〜４７０Ｎ。解除ピストン１０の外径、５０ｍｍ。
解除空気圧、０．３５ｍＭＰａ。
以上の条件で実施した結果、ブレーキ力（ロック力）、２５００Ｎの発生及び耐久性が確認されている。
［発明の効果］
１、ガイドレール１の取り付け面の対面１３と両傾斜面１１、１２を摩擦面とすることにより、ハウヂンク２のかんごう面に反力が生じるようにでき、このことが、小型で、且つ、強力なブレーキ力を可能とする。
２、停止位置でロックする場合に、ガイドレール１に接触する面が、ガイドレールの取り付け面に直角に移動するだけとなり、このことが、ロック位置の精度を上げることに貢献する。更に、ロック時に、ハウヂング２（接続ピン７）はガイドレール１に沿ったスライド方向のみならず直角方向にもロックされてる。[Example]
The guide table 8 is a rolling guide using a steel ball, and the result of the rail width of 25 mm is shown under the following conditions.
Material of housing 2 and brake member 3, ductile cast iron.
The outer diameter of the cylindrical roller 4 is 5 mm. Boosting wedge 5 wedge angle, 3.0 degrees. Spring force of spring 6, 330-470N. The outer diameter of the release piston 10 is 50 mm.
Release air pressure, 0.35 mMPa.
As a result of carrying out under the above conditions, it has been confirmed that braking force (locking force), 2500N and durability are generated.
[The invention's effect]
1. By making the facing surface 13 of the mounting surface of the guide rail 1 and the two inclined surfaces 11 and 12 into friction surfaces, a reaction force can be generated on the engraving surface of the housing 2, which is small in size, and Enables strong braking force.
2. When locking at the stop position, the surface in contact with the guide rail 1 only moves at right angles to the mounting surface of the guide rail, which contributes to increasing the accuracy of the lock position. Further, at the time of locking, the housing 2 (connection pin 7) is locked not only in the sliding direction along the guide rail 1 but also in the perpendicular direction.
