提供することを目的とする。[Detailed Description of the Invention] The present invention provides a track rail that has linear tracks on both sides, and a slide unit that straddles the track rail has a straight line opposite to the track rail track on its inner surface. In the linear motion rolling bearing, the slide unit has a raceway in the form of a shape, and the slide unit is capable of linear movement relative to the track rail via rolling elements interposed in both raceway surfaces. This relates to improvements in the mounting hole for screwing the mounting body placed and fixed onto the slide unit, and the shape of the mounting body allows for accurate and reliable screwing from either above or below the slide unit. The purpose is to provide a suitable mounting structure.

た。 As shown in FIG. 5, when attaching the attachment body 21 to the conventional slide unit 20, the upper surface of the slide unit 20 main body is surface-finished to serve as the attachment surface, and the attachment body 21 is usually attached to the required locations on the upper surface. It has a so-called top-tightening configuration in which a female thread 22 for screwing is drilled at a precise position and is used for screwing the bolt 23 from above the slide unit 20. As shown in FIG. If it is necessary to screw the mounting body 24 from below of the unit 20, insert and guide the bolt 25 from below at the required exact position, apart from the position of the female screw 22 on the main body of the slide unit 20. Guide hole 2
6 is drilled, a tightening bolt 25 is inserted into the guide hole 26 from below the slide unit 20, and the mounting body 24 is screwed. In order to tighten bolts at different positions, it is necessary to drill separate bolt holes for each bolt, and providing a rolling bearing that can be used for both top and bottom tightening increases the number of machining steps, which increases the number of machining positions. The slide unit 20 for drilling holes has become larger, and as a result, the entire mounting body including the slide unit 20 has become larger, which is contrary to the desire for compactness and light weight.

ていた。 In order to eliminate this drawback, there are two types of slide unit bodies of the same type, one with a female thread for top tightening and one with a bolt guide hole for bottom tightening. The main body of the slide unit must be manufactured in advance, which increases the amount of inventory and costs, and a solution to this problem has been desired.

As shown in FIGS. 1 and 2, mounting holes 9 as shown in FIG. 3 are bored at required positions indicated by chain lines A. A female thread 10 is formed in the upper half of the mounting hole 9, a guide cylindrical surface 11 is formed in the lower half, and the lower surface securely secures the head of a mounting bolt 15 from below around the mounting hole 19. A counterbore surface 12 is formed as a surface for adjusting the attachment. A finished mounting surface 13 on which the mounting body 8 is mounted and fixed is formed on the upper surface of the slide unit 2.

The length 1 is sufficient to reliably guide the mounting bolt 15 at an accurate position. In the illustrated example, the mounting bolt 14 has a larger diameter than the mounting bolt 15, and the guide cylinder surface 11 also serves as the pilot hole of the female thread 10, and the guide cylinder surface 11 is designed to prevent the mounting bolt 15 from sliding against the female thread 10. The inner diameter of the guide cylinder surface 11 and the outer diameter of the mounting bolt 15 fitted into the guide cylinder surface 11 are smaller than the inner diameter of the female thread 10.

の増大を防止に役立つものである。 As mentioned above, in the present invention, the upper female threaded portion and the lower bolt guide cylinder surface are formed in the same mounting hole, and the screwing between the slide unit and the mounting body placed on the slide unit is facilitated. By using mounting bolts with different bolt diameters, both top-tightening, in which the mounting bolts are tightened from above, and bottom-tightening, in which they are screwed in from below, can be used. In any case of tightening, it provides a mounting structure that allows the mounting body to be screwed in the correct position and reliably, and the slide unit has separate mounting holes for upper and lower tightening. There is no need for any special machining process, and the mounting holes can be fabricated by drilling the guide cylinder surface first, then using the guide cylinder surface as a pilot hole and machining the female thread. This is useful because the diameter and number of mounting holes can be kept to a minimum, so there is no reduction in component strength. There is no need to manufacture and store two types of slide units, which helps prevent increases in storage space and manufacturing costs.
