Abstract

PURPOSE:To permit the fixation of a table free from chattering by installing track rails, slide members, table, track rail fixing members, in a slide table device for machining equipment. CONSTITUTION:A pair of rails 4 having an H-shaped section are fixed onto a frame 13, and further a track rail 3 is fixed onto the rail 4, and a slide plate 2 fixed onto the track rail 3 through a slide unit 5 is shifted in the direction of arrow A by a feeding screw 11 and the nut of a nut holder 12 by turning a handle 9 in the direction of arrow C. When the slide plate 2 reaches a prescribed position, handles 7 installed onto the both sides of the slide plate 2 are turned in the direction of arrow B, and a plate 6 in the lower part is lowered by a screw, and pushes the upper surface of the track rail 3, and the slide plate 2 is pushed up and a hook 8 is hooked with the groove on the H- shaped rail, and the track rail 3 is pressed by the plate 6, and the slide plate 2 is fixed, and the fixation free from chattering is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a slide table device used in machining equipment and the like.

2. Description of the Related Art In the past, many techniques relating to slide table devices have been invented, and an example of a conventional table device will be described with reference to FIG. A pair of track rails 3 parallel to each other are provided on the frame 15, and the table 2 is slid onto the track rails 3 by a slide unit 5.
is provided. In other words, the table 2 is configured to move in a direction parallel to the track rail 3, that is, in the direction of arrow E. A nut holder 12 is provided on the back side of the table 2. Further, a feed screw 11 screwed into the nut of the nut holder 12 is rotatably attached to the frame 15 via a block 17, and a handle 9 for turning in the direction of arrow C is provided at the end of the feed screw 11. Also,
A lock handle 16 is attached to the block 17 to lock the feed screw 11 from rotating. By rotating the handle 9 in the direction of the arrow C as shown in the above configuration, the nut holder 12 and the plate 2 or the slide unit 5 move in the direction of the arrow E along the track rail 3, and the lock handle is rotated at an arbitrary position. 16 in the direction of arrow F and fixing the feed screw 11, the table 2 can be fixed.

Problems to be Solved by the Invention However, in the conventional configuration as described above, the feed screw 11 is locked so as not to rotate in order to fix the table 2, so when the table 2 is fixed, the feed screw 11
The table 2 had backlash due to the gap between the nut and the nut of the nut holder 12. Also, since the fixing device can only be provided at one location for each feed screw,
When there is only one number 1 and the width of the table is wide, a problem arises in that the wobbling becomes large. Accordingly, the present invention provides a slide table device that allows the table to play loosely when fixed.

Means for solving the problems and the technical means of the present invention for solving the above problems are a track rail, a slide member that moves along the track rail, a table provided on the slide member, and a table provided on the table. It consists of a fixed member that is provided and presses down the track rail.

Effect: With the above means, the table and the rail are connected to each other by the fixing member, so the table can be fixed without rattling.

Embodiment FIG. 1 is an overall perspective view of an embodiment of the slide table device of the present invention, and FIG. 2 is an enlarged sectional view of the main parts of this embodiment. In the figure, 13 is a frame, and frame 13
A pair of rails 4 having an FI-shaped cross section are fixed on the top in parallel. A pair of track rails 3 are each fixed to the upper part of the pair of rails 4, and a slide plate 2 is mounted on the track rail 3 via a slide unit 5 so as to slide in the direction indicated by the arrow. A nut holder 12 is fixed to the back surface of the slide plate 2, and a feed screw 11 is screwed into the slot of the nut holder 12. A handle 9 is provided at the end of the feed screw 11 and is attached to a block 10 that rotatably supports the feed screw 11 on a frame 13.

A pair of hooks 8 are provided on the back surface of the slide plate 2 for one of the rails 4, and the tip of the hook 8 is
It is arranged so as to fit into the groove of the rail 4 of the mold. A screw with a /'% handle 7 at the tip is screwed into the slide plate 2, and a plate 6 is attached to the bottom of the screw attached to the handle 7 to rotate the handle 7 in the direction of arrow B. As a result, the plate 6 descends in the direction of the arrow and presses down on the upper surface of the track rail 3.

Next, the operation of this embodiment will be described. First of all 1nd dollar 9
When turned in the direction of arrow C, the feed screw 11 rotates, the nut of the nut holder 12 is driven, and the slide plate 2 moves along the pair of track rails 3 in the direction of arrow A. When the slide plate 2 reaches the target position, the handles 7 are rotated in the directions of arrows B. Then, the screw at the bottom of the handle 7 screwed into the slide plate 2 causes the plate 6 to descend in the direction of the arrow and press against the top surface of the track rail 3. Then, the slide plate 2 is pushed upward due to the reaction of this pressing force. Here, two seven-piece hooks 8 are placed in the grooves of the H-shaped rail 4 on the back surface of the slide plate 2, so the tips of the hooks 8 are caught in the upper part of the grooves of the rail 4. Therefore, the upper surface 14 of the tip of the hook 8 and the surface of the groove of the rail 4 come into pressure contact, and the upper surface of the track rail 3 and the plate 6 come into pressure contact, and the slide plate 2
becomes fixed.

Effects of the Invention As described above, the present invention provides an H-shaped rail, a hook whose tip is inserted into the groove of the rail, and a handle for holding down the top surface of the track rail, thereby fixing it to the slide table rail. There is no play after fixing, and fixing means can be provided regardless of the number of feed screws.
