Abstract

A press-fitting jig for a closure cap which is configured to press-fit a closure cap into a bolt mounting hole formed in a track rail of a guide device. The press-fitting jig is mounted to a moving block, which is assembled to the track rail through intermediation of a plurality of rolling elements and is configured to move on the track rail. The press-fitting jig includes: a finishing surface which is brought into slide contact with an upper surface of the track rail having the bolt mounting hole opened therein; and a guide surface, which is formed adjacent to the finishing surface and forms a wedge-shaped space with the track rail in a longitudinal direction of the track rail, the guide surface being configured to push the closure cap temporarily placed in the bolt mounting hole into the bolt mounting hole along with movement of the moving block.

First claim

The invention claimed is:

1. A press-fitting jig for a closure cap, the press-fitting jig being configured to press-fit a closure cap into a bolt mounting hole formed in a track rail of a guide device,
the press-fitting jig being mounted to a moving block, which is assembled to the track rail through intermediation of a plurality of rolling elements, and is configured to move on the track rail,
the press-fitting jig comprising:
a finishing surface which is brought into slide contact with an upper surface of the track rail having the bolt mounting hole opened therein; and
a guide surface, which is formed adjacent to the finishing surface and is inclined along a longitudinal direction of the track rail to form a wedge-shaped space with the track rail, the guide surface being configured to push the closure cap temporarily placed in the bolt mounting hole into the bolt mounting hole along with movement of the moving block,
wherein the guide surface is formed into a recessed curved surface shape along a width direction of the track rail,
wherein a sectional shape of the wedge-shaped space along the width direction of the track rail is an arch shape, and
wherein a size of the arch shape of the sectional shape of the wedge-shaped space is gradually reduced from an end surface of the press-fitting jig both in a width direction of the track rail and in a longitudinal direction of the track rail.

2. The press-fitting jig for a closure cap according to claim 1 , wherein the press-fitting jig is mounted to the moving block with a holding plate fixed to a mounting surface for mounting a movable body to the moving block.

3. A press-fitting jig for a closure cap, the press-fitting jig being configured to press-fit a closure cap into a bolt mounting hole formed in a track rail of a guide device,
the press-fitting jig being mounted to a moving block, which is assembled to the track rail through intermediation of a plurality of rolling elements, and is configured to move on the track rail,
the press-fitting jig comprising:
a finishing surface which is brought into slide contact with an upper surface of the track rail having the bolt mounting hole opened therein; and
a guide surface, which is formed adjacent to the finishing surface and is inclined along a longitudinal direction of the track rail to form a wedge-shaped space with the track rail, the guide surface being configured to push the closure cap temporarily placed in the bolt mounting hole into the bolt mounting hole along with movement of the moving block,
wherein the guide surface has a pair of pressing flat surfaces inclined with respect to the finishing surface,
wherein a sectional shape of the wedge-shaped space along a width direction of the track rail is a triangular shape, and
wherein a size of the triangular shape of the sectional shape of the wedge-shaped space is gradually reduced from an end surface of the press-fitting jig both in a width direction of the track rail and in a longitudinal direction of the track rail.

4. The press-fitting jig for a closure cap according to claim 3 , wherein the press-fitting jig is mounted to the moving block with a holding plate fixed to a mounting surface for mounting a movable body to the moving block.
