台の改良に関する。[Detailed description of the invention] The present invention relates to an improvement of the track base of a linear motion bearing, that is, a linear sliding bearing unit, which is incorporated into the sliding part of general industrial machinery such as the XY axis automatic exchange device of machine tools such as machining centers and NC machines. .
従来の軌道台は、第１図に示す如く上部平坦面

（実開昭50−66057号公報参照）
上部軌道台の底面取付面に逃げ７を形成する理
由は研削仕上げ面積をより少なくすることによつ
てコスト低減ができるとともに、両側面との直角
度を出し易すくなるからである。 As shown in Fig. 1, the conventional track base has an upper flat surface 1 and a bottom mounting surface 2 that are parallel to each other, and load ball grooves 3 and 4 that guide and support bearings via balls are formed at required locations. Both lower side surfaces 5 and 6 are formed at right angles, reliefs 7 are formed in the axial direction at required locations on the bottom mounting surface 2, and the upper flat surface and the bottom mounting surface are connected at required intervals. A penetrating mounting hole 8 is formed.
(Refer to Japanese Utility Model Application Publication No. 50-66057) The reason for forming the relief 7 on the bottom mounting surface of the upper track is to reduce the cost by reducing the grinding area and to reduce the perpendicularity with both sides. This is because it becomes easier to take out.
ところが、該軌道台を工作機械等のベツドの所
要個所に複数本のボルトを介して取付けるさい、
取付孔８（D0）が取付部２（H0）より小さいた
め、ボルトの締めつけ具合によつては相手取付面
に完全に締結されている部分と不完全に締結され
ている部分が生じ軌道台が上記ベツドと平行に取
付けができない。 However, when attaching the track to the required location on the bed of a machine tool, etc. via multiple bolts,
Since the mounting hole 8 (D 0 ) is smaller than the mounting part 2 (H 0 ), depending on the tightening condition of the bolt, some parts may be completely fastened to the mating mounting surface and some parts may be incompletely fastened to the other mounting surface. The stand cannot be installed parallel to the bed above.
また、ボルトの締め付け力をアツプしてもボル
トの伸び度合と軌道台の曲り度合により締付力に
より締付力に差が生じ、軌道台が上記ベツドと平
行に取付けることができない欠点を有する。 Further, even if the tightening force of the bolt is increased, there is a difference in the tightening force depending on the degree of elongation of the bolt and the degree of curvature of the way, and there is a drawback that the way way cannot be installed parallel to the bed.
本考案の技術的課題は工作機械等に軌道台を取
付けるさいに軌道台の撓みを防ぐとゝもにボルト
の締付け力の大小に関係なく、相手部材に確実に
締結することにある。 The technical problem of the present invention is to prevent the wayway from deflecting when it is attached to a machine tool, etc., and to securely fasten it to a mating member regardless of the magnitude of the tightening force of the bolt.
上記技術的課題を解決する本考案の構成、すな
わち技術的手段は次の通りである。 The configuration of the present invention, that is, the technical means for solving the above technical problems, is as follows.
上部平坦面と底面取付面が軸方向平行に形成さ

る。 In a track base in which an upper flat surface and a bottom mounting surface are formed parallel to each other in the axial direction, and load ball raceway grooves are formed parallel to the axis and two grooves on each side, the bottom mounting surface is provided with relief. This is a track base for linear sliding bearings, which is formed on both sides of the mounting surface with the center of the mounting surface having a width equal to or smaller than the bolt hole.

ボルト孔Ｄの口径に等しいかあるいはそれより
やゝ小さいため、取付け相手部材との単位面積当

に一致することができる加圧機能を有する。 The above technical means provides the following effects. When the bolt is tightened, the width H of the central mounting surface is equal to or slightly smaller than the diameter of the bolt hole D, so the contact surface pressure per unit area with the mating member increases, making it difficult to connect to the flat mating member. With pressurization function that can be perfectly matched.
従つて、軌道台の底面取付面と平行に形成され
