Description

[Detailed Description of the Invention] The present invention particularly relates to a three-dimensional marking and measuring device that has an improved surface plate and a sliding table that can slide on the surface plate.

Various types of three-dimensional marking and measuring devices for measuring the size of workpieces are already known, ranging from large ones to small ones. A member having a linear guide groove or a similar guide groove is provided, and a sliding table supporting the measuring rod is fitted into the guide grooves, so that the sliding table can be moved appropriately along the guide groove. It is composed of

However, although the sliding mechanism of this slide table is easily slid in the direction of the guide groove, it must be completely prevented from moving in the direction perpendicular to the guide groove, that is, from lateral vibration. This type of conventional product has a complicated structure, and therefore the number of parts and members increases.
There were drawbacks such as increased labor costs and increased costs.

The present invention was made to eliminate such drawbacks.
The present invention has developed a mechanism that can accurately and easily move the sliding table in one direction on the surface plate with an extremely simple structure.

That is, to describe the present invention in detail, it includes a surface plate, a sliding table that slides on the surface plate, a vertical rod that stands upright on the sliding table, and a vertical rod that is horizontally supported by the vertical rod via a holder. In a three-dimensional marking and measuring device having a horizontal rod with a scriber at its tip, convex rails having vertical surfaces on both sides in the longitudinal direction are fixed to the surface plate, and a convex rail having vertical surfaces on both sides in the longitudinal direction is fixed to the surface plate. A pair of guide rolls that roll in contact with vertical surfaces on both sides of the convex rail and an adjustment mechanism for finely adjusting the sliding table are provided, and the adjusting mechanism is configured to adjust the sliding rod to the sliding table. It consists of a base member connected through the rail and a tightening screw for fastening the base member to the rail.

Therefore, according to the present invention, it is possible to linearly reciprocate the sliding table on the surface plate with an extremely simple mechanism, and the sliding table can be slightly moved or fixed as necessary, which has practical benefits. There are many things.

The present invention will be described in detail below based on embodiments shown in the drawings.

Reference numeral 1 designates a surface plate, and a rail 2 having a rectangular cross section and having vertical surfaces 2' on both sides protrudes from the surface plate 1.

Reference numeral 3 denotes a sliding table that can slide on the surface plate, and sliding rollers 4 that are joined to the surface plate are provided on both sides of the bottom surface of the sliding table 3.

Furthermore, the center of the bottom surface of the slide table 3 is formed into a recess 3' that can avoid the rail 2, and within this recess 3' are a pair of horizontal rollers that are joined to both vertical surfaces 2' of the rail 2. 5 is held by a support shaft 6.

As this support shaft 6 is an eccentric shaft as is clear from FIG. 2, by appropriately rotating the eccentric shaft 6, the gap between the opposing rollers 5 and 5 can be freely adjusted. As a result, the pressing force between the rail side surface 2' and the roller 5, that is, the gap between the roller 5 and the rail can be adjusted as appropriate.

7 is a screw for fixing the eccentric shaft 6 to the sliding table 3.

Reference numeral 8 designates a fine movement adjuster for the sliding table 3, which has a recess 9 into which the rail 2 is loosely fitted, and is connected to the sliding table 3 by a threaded rod 10. It consists of a base member 11, a tightening rod 12 that passes through the recess 9 provided in the base member 11 at right angles, and a nut 12' that engages with the screw rod 12. ′
By tightening the threaded rod 12, the inner surface of the recess 9 and the rail side surface 2' are pressed together, and the fine adjustment mechanism
is fixed to the rail 2 and the sliding base is accordingly fixed, and if the rod 10 is rotated when the adjuster 8 is fixed, it will slide due to the action of the spring interposed in the screw 7. This causes the table 3 to move slightly.

13 is a vertical rod supported vertically on the sliding table 3; 14;
is a horizontal rod held horizontally by the vertical rod 13 via a holder 15;

16 is a scriber attached to the tip of the horizontal rod 14
It is.

The present embodiment is constructed as described above, and the surface plate 1 is provided with a rectangular rail 2, and the slide table 3 is connected to the vertical side surface of the rail 2, which runs on the surface plate. Since the slide table 3 is provided with a pair of rollers 5, the slide table 3 can linearly slide along the rail 2, and each roller 5 is supported by an eccentric shaft 6. Therefore, the gap between the roller and the rail can be eliminated by the eccentric shaft, and highly accurate linear sliding can be achieved while preventing lateral vibration.

Further, the sliding table 3 can be fixed at a desired position by the fine movement adjuster 8, and if necessary, the sliding table 3 can be finely moved by the spring action interposed in the screw 7, and the mechanism is relatively simple. This has the advantage that a highly accurate three-dimensional scribing and measuring device can be obtained.
