ーブル等の直線運動部分の案内に用いられる直線
運動軸受の軌道台の取付構造に関する。[Detailed Description of the Invention] Industrial Application Field This invention relates to a mounting structure for a track base of a linear motion bearing used for guiding a linear motion part such as a table of a machine tool or a positioning table.

ような方式が用いられていた。Prior art and its problems Linear motion bearings usually have the following characteristics, as shown in FIG.
A bearing body 2 is provided so as to straddle the track 1, and a ball (not shown) is endlessly circulated between the two to guide linear motion.
Conventionally, the method shown in FIGS. 4 to 7 has been used to attach the track 1 to a mounting base such as the bed of a machine tool.

けるようにしたテーパーギブ方式である。 In FIG. 4, the track 1 is inserted into a groove 3' provided in the mounting base 3, and is fixed by pressing it from the side with a push screw 4. In the case shown in FIG.
This is a method in which the track 1 is placed on a step 3'' provided on the mounting base 3, and a push plate 6 is pressed from the side via a screw 5. The one shown in Fig. 6 is a track 1 inserted into the groove 3. This is a taper give system in which the track 1 is pressed by tightening a tapered push plate 7 with bolts 8.

As shown in FIG. 7, the push plate 7' is fixed to the mounting base 3 with a pin 8', and
It was based on a method in which the track base 1 was attached to the base and the dowel pins 9 were press-fitted and fixed.
この場合、テーブル、ベツド等相手側の取付け
基準面、取付面を高精度に加工し、正しく組付け

高い精度を出すことは困難であるという問題があ
つた。また、取付けも部品点数が多く面倒であつ
た。 In this case, a high degree of accuracy is required on the mounting surface because stable functionality can only be obtained by processing the mounting reference surface and mounting surface of the mating side such as the table or bed with high precision and assembling it correctly. Despite this, the pressing force of the wayway (which is usually deformed due to heat treatment, etc.) acts only partially, so the deformation of the wayway is not completely corrected.
The problem was that it was difficult to achieve high accuracy. Furthermore, installation was troublesome due to the large number of parts.

えるようにしたものである。Means and Effects for Solving Problems This device forcibly fits into both side walls of a concave or convex portion provided on the mounting base, and only one of the two planes of different heights formed on the mounting base. By using a mounting structure in which a convex portion or a concave portion for fitting is provided on the track base so as to be in planar contact with the base plate, the track base can be mounted to the base easily and with high precision.

By simply tightening the bolts after fitting the two together, deformation of the track is corrected as a result of the forced fit, allowing for highly accurate installation.
実施例
以下、本考案の実施例を添付図面に基づいて説
明すると、
第１図に示したものは、軌道台１０側に凸部１
１を、取付台３０側に凹部３１を設けたものであ
つて、この場合、軌道台１０の凸部１１の高さは
取付台３０の凹部３１の深さよりも短くなつてい
るので、取付台と軌道台とは、軌道台１０の左右
両端部において互いに平面接触するようになる。
この接触の関係は、中央部と端部とを逆の関係に
してもよいことは勿論である。軌道台１０に設け

ができるので、この標準化されたものに従つてそ
の対応する幅及び深さの凹部を取付台に加工する
だけで簡単に軌道台を取付台に取付けることがで
きるようになる。Embodiment Hereinafter, an embodiment of the present invention will be explained based on the attached drawings.The embodiment shown in FIG.
1 has a recess 31 on the side of the mounting base 30. In this case, the height of the protrusion 11 of the track 10 is shorter than the depth of the recess 31 of the mounting base 30, so the mounting base and the track base come into plane contact with each other at both left and right end portions of the track base 10.
Of course, this contact relationship between the center portion and the end portions may be reversed. Since the width and height of the convex portion 11 provided on the track base 10 can be standardized, it is easy to simply process a concave portion of the corresponding width and depth into the mounting base according to the standardized values. The track base can now be attached to the mounting base.
軌道台１０の凸部１１を取付台３０に設けた凹
部３１の両側壁に強制的に嵌め合せたのち、ボル
ト４０によつて固定する。その結果、軌道台１０
は、熱処理等の変形があつても、取付台３０の凹
部３１の両側壁によつて矯正されて、高精度の取
付けを行うことができる。 After the protrusion 11 of the track base 10 is forcibly fitted into both side walls of the recess 31 provided in the mounting base 30, it is fixed with bolts 40. As a result, orbital platform 10
Even if deformation occurs due to heat treatment or the like, it is corrected by the both side walls of the recess 31 of the mounting base 30, so that highly accurate mounting can be performed.
次に第２図に示したものは、軌道台１０′側に
凹部１１′を、取付台３０′側に凸部３１′を設け
たものであつて、この図に示すものにおいては、
取付台３０′側の凸部３１′の高さが軌道台１０′
側の凹部１１′の深さよりも大きくなつているの
で、両者は中央部において平面接触し、両端部に
おいては離れている関係になる。この接触関係
も、第１図の場合と同様に逆にしてもよいことは
勿論である。第１図の場合と同様に、両者は嵌め
合わせたのちボルト４０′によつて固定する。な
お、軌道台又は取付台に設けられる凸部又は凹部
は必ずしも長手方向に切れ目のない連続形状であ
る必要はない。 Next, the one shown in FIG. 2 has a recess 11' on the track 10' side and a convex part 31' on the mounting base 30' side.
The height of the protrusion 31' on the mounting base 30' side is the same as the track base 10'.
Since the depth is greater than the depth of the side recess 11', the two are in planar contact at the center and are separated at both ends. Of course, this contact relationship may also be reversed as in the case of FIG. As in the case of FIG. 1, the two are fitted together and then fixed with bolts 40'. Note that the convex portions or concave portions provided on the track base or the mounting base do not necessarily have to have a continuous shape without any breaks in the longitudinal direction.
考案の効果
本考案は、以上のように構成したものであるか
ら、軌道台の取付台に対する位置決めを嵌め合い
によつて容易に行うことができるとともに、軌道
台を取付台に強制嵌め合いすることにより、軌道
台は取付台の精度にならつて位置決めの精度を出
し易いという特徴がある。Effects of the invention Since the present invention is constructed as described above, it is possible to easily position the track base with respect to the mounting base by fitting it together, and it is also possible to forcibly fit the track base to the mounting base. Therefore, the track base is characterized in that it can easily achieve positioning accuracy comparable to that of the mounting base.
さらに、取付台と軌道台とを凸部と凹部の形成
の結果としてできる高さの異なる２つの平面の一
方のみで平面接触するようにしたことから、水平
方向の相互の接触面積を少なくして接触面の精度
が出し易くなつて高精度の取付けが可能であると
ともに、取付台の接触面の垂直方向真直度を出し
て、軌道台の垂直方向真直度に転写することがで
きる。そして、従来の取付け方式に比べれば、加
工コストも安くなる効果がある。 Furthermore, since the mounting base and the track base are in plane contact only on one of the two planes with different heights that are created as a result of the formation of the convex part and the concave part, the mutual contact area in the horizontal direction is reduced. This makes it easier to improve the accuracy of the contact surface, allowing for high-precision installation, and also allows the vertical straightness of the contact surface of the mount to be improved and transferred to the vertical straightness of the track base. Furthermore, compared to conventional mounting methods, processing costs are also reduced.
