ある。In this product, a table (slider) and a bed (guide rail) each made of a thin steel plate having a substantially U-shaped cross section are superposed so that their bottom faces face each other with the bed facing outward, and they face each other in the longitudinal direction of the overlapped portion. A circulator having an infinite circulation path through which the rolling elements infinitely circulate through each of the raceway grooves is fixed in the table, and a large number of rolling elements are provided in the infinite circulation path of the circulator. In a linear motion rolling bearing (miniature linear guide device) in which the table and the bed are slidably fitted to each other via the rolling elements. There is no raceway groove, and a projecting portion having a mounting portion with another member is formed.

形が及ばず、従って精度の狂いは防止できる。With this, for example, even if the protrusion is deformed when a fastening member such as a bolt is attached to the mounting portion and tightened and the bed is fixed to another member, the deformation does not extend to the side surface of the bed having the raceway groove. You can prevent the accuracy from going wrong.

問題点があった。However, in the above-mentioned conventional miniature linear guide device, since the mounting portion for the other member is formed by forming the projecting portion that extends the both ends in the longitudinal direction of the table or bed, the total length of the bed (guide rail) is reduced. Since the length of the desired track groove is longer than the desired total length, there is a problem that it becomes difficult to use when there is no mounting space for mounting in a small precision device such as a robot or an information device.

た。The present invention to achieve the above-mentioned object is to provide a guide rail having a U-shaped cross section with axial rolling element rolling grooves formed on both inner surfaces thereof, and a U-shaped cross section having a bottom surface facing the guide rail. A slider having a rolling element rolling groove formed on its outer surface, which is loosely fitted together and faces the rolling element rolling groove of the guide rail, a rolling element rolling groove of the guide rail, and a rolling element rolling of the slider. In a miniature linear guide device including a number of rolling elements that are fitted into a rolling element raceway groove formed by a groove and roll with the movement of the slider, a bottom center portion at both end portions of the bottom surface of the guide rail. Leaving both sides, the both sides are cut out in the axial direction from the ends to form a mounting surface isolated from both side surfaces, a mounting hole is provided at the center of the mounting surface, and a guide rail is provided at the base of the mounting surface. To other parts To form a kick for preventing deformation perforation of time.

けスペースが少なくて済む。Fastening members such as bolts are inserted into the mounting holes of the mounting surface formed on the bottom surfaces of both ends of the guide rail, and fixed to the mounting surface. In that case, the mounting surface is completely separated from the side surface of the guide rail by the notch, and the deformation of the mounting surface is absorbed by the deformation preventing holes of the base, and the deformation by the fastening member does not extend to the guide rail track portion. Absent. Therefore, the phenomenon that the movement accuracy of the slider is lowered before and after mounting does not occur. Further, since the mounting surface does not protrude from the end of the guide rail, the mounting space is small.

済む。Fastening members such as bolts are inserted into the mounting holes 4 of the mounting surface 2 formed at both ends of the guide rail 1 and fastened to the mounting surface of another member. In that case, the mounting surface 2 is completely separated from the side surfaces 1b, 1c of the guide rail by the notch 3, and the deformation of the mounting surface 2 is absorbed by the deformation preventing perforations 5 in the base. Therefore, even if the mounting surface 2 is deformed due to the tightening of the fastening member, the deformation does not reach the portions of the guide rails 1A and 1B. That is, the phenomenon that the side surfaces 1a and 1b are pulled inward due to the bending of the bottom surface 1a of the guide rail 1 does not occur. Therefore, the parallelism of the both side surfaces can be strictly maintained, and the movement accuracy of the slider 9 does not decrease before and after mounting. Further, since the mounting surface 2 does not project from the end portion of the guide rail 1 as in the conventional case, the mounting space can be reduced.

るように循環する。Thus, when the guide rail 1 is attached to another member and the slider 2 is moved rearward in the axial direction, the guide rail 1
The ball B inserted in the raceway groove 12 provided between the slider 9 and the slider 9 rolls as the slider 9 moves, and moves in the direction opposite to the moving direction of the slider 9. The protrusions 28a, 28b of the ball guide member 20 are provided at the end of the race member 10.
The direction is changed by the end portions 29a and 29b having an acute angle, the U-turn is made along the curved ball passages 26a and 26b, and the curved ball passage 2 on the opposite side is passed through the ball circulation passage 27.
It makes a U-turn again by 6a and 26b and circulates back to the track groove 12.

長い長穴とした点が第１の実施例とは異なっている。In this embodiment, in forming the mounting surface 2 at the end of the guide rail 1, the notch 3 does not affect the rail side surfaces 1b and 1c, and only the bottom surface 1a is notched. This is different from the first embodiment in that the perforation 5 for preventing deformation formed in the base portion of 2 is an elongated hole which is long in the axial direction.
このように固定装置を構成すると、案内レールの側面１
ｂ，１ｃの端部の剛性が大きくなるという利点がある。When the fixing device is configured in this way, the side surface 1 of the guide rail is
There is an advantage that the rigidity of the ends of b and 1c is increased.

ガイド装置に対しても適用可能である。In addition, the slider is assembled inside the guide rail, and the rolling elements are designed to infinitely circulate in the raceway and the circulation path.However, the slider is mounted on the outside of the guide rail and assembled on both sides. The rolling elements in the raceway groove can also be applied to a miniature linear guide device configured to be held by a retainer without being infinitely circulated.

果がある。As described above, according to the present invention, the mounting portions at both end portions of the guide rail are retracted from the rail end instead of being the protruding portions extending in the longitudinal direction from the rail end, and the rail side surface has a notch. It was formed so as to be isolated through. Therefore, the total length of the guide rail is not longer than the required total track length, and there is an effect that a small mounting space is sufficient.

ニアチュアリニアガイド装置の固定装置。1. A guide rail having a U-shaped cross section and having axially formed rolling element rolling grooves formed on both inner side surfaces, and a guide rail formed in a U-shaped cross section and having a bottom face facing each other and being loosely fitted. And a slider having an outer surface formed with a rolling element rolling groove facing the rolling element rolling groove of the guide rail, a rolling element rolling groove of the guide rail, and a rolling element rolling groove of the slider. In a miniature linear guide device including a large number of rolling elements that are fitted into a rolling element raceway groove that rolls with the movement of the slider, both end portions of the bottom surface of the guide rail are left with a bottom center portion. A side is axially cut away from the end to form a mounting surface that is isolated from both sides, a mounting hole is provided in the center of the mounting surface, and a guide rail is provided at the base of the mounting surface for other members. Prevents deformation when installing Fixing device of miniature linear guide device, characterized in that the formation of the perforation.
