置に関するものである。[Detailed description of the invention] [Industrial application field] The present invention is a linear guide device consisting of a rail and a sliding body that slides on the rail, and in particular aims to reduce the weight of the sliding body and improve responsiveness. The present invention relates to a linear guide device.

て従来から材質には一般に鋼が用いられている。[Prior Art] As shown in FIG. 9, a linear guide device generally includes a long rail 10 and a saddle-shaped sliding body 14 that is slidably placed on the long rail 10 through rolling of balls 12. (Although not shown, an end cap is fixed to the end surface of the sliding body 14.) Conventionally, the rail 10 and the sliding body 14, which constitute the main parts of the linear guide device, are generally made of steel in consideration of load capacity and rigidity.

実用化されていない。 However, in many linear guide devices used in information equipment, the sliding body is required to have a long response even though it has a light load.In the conventional linear guide device, the sliding body 14 is heavy, so The inertia becomes large, and a large force is required to drive and stop the sliding body 14, which adversely affects the sliding speed and positioning accuracy of the sliding body. This corresponds to the sliding body 14 required for linear guide devices in recent years.
This method does not meet the demands for high precision and high speed positioning. There are also known examples in which sliding bodies are made of synthetic resin to make them lighter (for example, in JP-A-59
-208217), the conventional one had a complicated structure.
A simple and inexpensive linear guide device in which the ball rolling portion of the sliding body is highly wear resistant and rigid enough not to deform when a load is applied has not yet been put into practical use.

目的としてなされたものである。 The present invention aims to eliminate the drawbacks of the above conventional examples, namely, to reduce the weight of the sliding body by making it from synthetic resin, to sufficiently increase the wear resistance of the rolling parts and the rigidity of the entire sliding body, and to improve the structure. The purpose of this invention is to provide a linear guide device that can be easily manufactured at low cost.

A reinforcing member made of a steel plate in which a moving groove was formed was attached, and this reinforcing member formed a ball rolling groove. In this way, the weight of the sliding body can be halved compared to the conventional one, and the inertia can be reduced, allowing highly accurate positioning and high-speed sliding.

and a connecting portion 34 that connects the two, and has a saddle shape. Epoxy concrete contains approximately 30% carbon fiber to improve its strength. A ball return hole 36 is drilled through the sleeve portion 32 in the longitudinal direction, and a recess 38 with a semicircular cross section (larger than the ball diameter) is provided on the inner surface of the sleeve portion 32 along its entire length. It is formed as follows.
A reinforcing member 70 (FIG. 6), which will be described later, is attached to the recess 38. Bolt holes 39 for bolts for attaching the end caps 50a, 50b to the sliding body 30 are drilled at the ends of the sleeve portion 32, and bolt holes 39 for attaching the sliding body 30 to a moving table (not shown) are provided on the upper surface of the sleeve portion 32. A bolt hole 42 is drilled for the purpose.

The radius of the groove is slightly larger than the radius of the ball, and the inner diameter surface of the groove forms the ball rolling groove 72. To attach the reinforcing member 70 to the sliding body 30, a positioning protrusion and a coupling protrusion are formed on the lower surface of the sliding body connecting part 34, the positioning protrusion is engaged with the notch 78, and the coupling protrusion is circularly inserted. All you have to do is fit it into the hole 76 and crush its tip. Further, as shown in FIG. 8, instead of the circular hole 76, a cylindrical raised part 84 whose diameter gradually decreases is used.
It is also possible to prepare a reinforcing member 86 in which a reinforcing member 86 is formed, and insert a coupling protrusion formed on the lower surface of the sliding body connecting part 34 into this raised part 84, and heat caulk or ultrasonically weld the tip end thereof. .

る。 The sliding body 30 is slidably attached to the rail 20 via balls 66 filled between the ball rolling grooves 22 and 72 (which may be semicircular or gothic arch shaped). Ball return hole 36 of sliding body 30
Balls 66 are also filled in the ball circulation groove 54 of the end cap 50 (see FIG. 2).
When a driving force is applied to the moving table and the sliding body 30 moves in either direction on the rail 20, the balls 66 between the ball rolling grooves 22 and 72 are removed from the ball circulation groove as the sliding body 30 slides. The ball reaches the ball return hole 36, moves inside the ball return hole 36 in the opposite direction to that described above, and returns from the ball circulation groove 54 to the ball rolling grooves 22 and 72. In addition,
The linear guide device of this embodiment is suitably used for a carriage of a computer disk device and for guiding a movable part by parallel movement of a measuring or measuring instrument.

れるのである。 In this embodiment, since the sliding body 30 is made of a strong synthetic resin structure, it is much lighter and has a smaller inertia than when it is made of metal. Therefore, the sliding body 30 can be slid quickly with a relatively small force, and similarly, the sliding body 30 can be stopped with a small force and positioned with high accuracy. Moreover, since the reinforcing member 70 made of a steel plate is fixed to the ball rolling portion, there is no fear that the ball rolling groove 72 will wear out. Since the reinforcing member 70 is provided with a notch 78, positioning can be performed correctly and the balls 66 can circulate smoothly. In addition, the above advantages can be obtained with almost no changes to the configuration of the conventional linear guide device, without adding any unnecessary members or unnecessarily complicating the structure.

For example, the shape and number of ball rolling grooves, the cross-sectional shapes of rails and sliding bodies can be changed, It can be improved.

Therefore, the reinforcing member does not rotate and come into contact with the rail, and when preload is applied to the ball, the springiness of the reinforcing member can be used, so the preload is stabilized. Therefore, it is possible to slide the sliding body at high speed and position it with high precision, and this effect can be achieved without impairing the rigidity of the sliding body or the wear resistance of the ball rolling groove. be.
