Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a table sliding device, and more particularly to a device for sliding a table for centering in mechanical work in the horizontal or vertical directions.

Conventionally, to move this type of table in one direction, as shown in FIG. 1, a sliding table 2 is placed on a base 1 having a sliding guide surface, and a motor 4 is moved.
By rotating the lead screw 3, the sliding table 2 was slid in the axial direction of the lead screw 3. In addition, in order to slide the table in two orthogonal directions, that is, vertically and horizontally, as shown in FIG. A first sliding table 5 having a sliding guide surface that guides in a direction perpendicular to the guiding direction of the base 1 is installed so as to slide on the guide surface of the base 1 by a lead screw 3 that rotates in conjunction with a motor 4. , the first sliding table 5 is also operated by a lead screw 3' which rotates in conjunction with the motor 4'.
An XY table was formed on which a second sliding table 6 was installed to slide on the guide surface of the sliding table 5.

In these conventional systems, in the case of one-way sliding, there are two stages, the base 1 and the table 2, and the two stages are orthogonal.
In the case of directional sliding, there is a three-stage structure consisting of the base 1, the first sliding table 5, and the second sliding table 6, and in any case, the height from the bottom of the base 1 to the top of the table increases, resulting in a decrease in rigidity. The drawback was that it required a large installation space.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a compact sliding table device with a simple structure and a reduced height from the bottom of the base to the top of the table.

In order to achieve this object, the present invention includes a base provided with open grooves or penetrating grooves, which will be described later, and a table slidably installed inside the grooves.
Furthermore, one or two pairs of table sliding means are disposed oppositely between the base and the table, so that the table can be moved in one direction or in the vertical and horizontal directions within the groove.

Further, the present invention will be explained in detail with reference to illustrated embodiments. The first embodiment is shown in FIGS. 3 and 4,
A table 12 having a rectangular cross section is installed inside a base 11 provided with an open groove G that opens only on one side (here, the top surface) so as to be slidable in the direction of arrow X (here, the horizontal direction). . And table 1
Both vertically opposing sides of 2 are sliding surfaces S ₁₂ , S′ ₁₂
These sliding surfaces and the open groove G of the base 11 are formed.
The opposing sliding surfaces S ₁₁ and ' ₁₁ of the table slide, and both bottom surfaces of the table and the base also slide. Further, a pair of table sliding means arranged opposite to each other in the lateral direction are formed so as to move the table 12 laterally in conjunction with each other. That is, as shown in the figure, 2 is inversely symmetrical.
Tapered sliders 13a, 13b
are slidably fitted between the open groove G and the sliding surfaces on both sides of the table 12, and are connected to the motors 15a and 1, respectively.
5b and screws 13, 13b screwed onto the table 11 are fixed thereto. In order to provide high rigidity to these tables and bases and to facilitate manufacturing, the table 11 is provided with dovetail grooves as shown in Fig. 4, and the sliding surfaces S ₁₁ , S ₁₂ and S ₁₁ , S' ₁₂ are truncated. It is desirable to have an equilateral triangular cross-sectional shape. Formed in this way, both table sliding means 13a, 14
When a, 15a and 13b, 14b, 15b are interlocked, the table 12 slides in the open groove G, and the taper sliders 13a, 13b slide from the positions A, B to the positions A', B' as shown in FIG. Accordingly, the table 12 slides in the direction of the arrow from position C to position C'. Of course, if the motor is rotated in the opposite direction, the table 12 will slide in the opposite direction of the arrow.

A second embodiment is shown in FIGS. 6 and 7, with a through-groove
A table 2 is mounted on a frame-shaped base 21 with G′.
2 is installed internally, and two pairs of table sliding means are arranged vertically and horizontally to form an XY table. With the same structure as above, taper sliders 23a and 23b are arranged laterally opposite each other and are partially inserted and slidably fitted into the base 21 and table 22, respectively, as shown in the figure, and the screws 24a and motor 25a and the horizontal table sliding means 23a, 24a, 25
a and similar means 23b, 24b, 25
b are provided opposite each other, and a vertical table sliding means 23 is provided.
c, 24c, 25c, 23d, 24d, and 25d are arranged to form an XY table. Its operating state is shown in () and () in Figure 8, as shown in 1.
The pair of table sliding means interlock, and the taper sliders 23a and 23b move from A to A' and from B to B', respectively, and the table 22 slides in the lateral direction of the arrow. In addition, the other table sliding means is interlocked to move the taper sliders 23c and 23d from E to E.
Moving from E' and F to F', the table 22 slides vertically from D to D'.

The next example that improves these is shown in Figures 9 and 10.
As shown in the figure, a roller-shaped roller 26 or a ball 27 is interposed between the two sliding surfaces that are in contact with each other to reduce the sliding frictional resistance. A roller 26 is provided on the one-way sliding surface, a large number of balls 27 are provided on the XY-direction sliding surface, and a retainer R is provided to maintain the spacing between the rollers. The taper slider 23 is shaped so that the table 22 does not come off from the open groove G while the table is sliding, and the example shown in FIG. 10 is easy to manufacture. In the embodiment shown in FIG. 11, a holding plate 28 having an I-shaped cross section and a coiled spring 2 are used as shown in the figure.
9 is used to press the table 22 against the base so that the table 22 does not come off from the open groove G and no sliding movement occurs.

Another example is shown in Fig. 12, and an explanatory diagram of the operation is shown in Fig. 13.
Shown in Figure. In order to place the table and base in parallel in the second embodiment, instead of the taper slider 23, four sets of fixed tapers 34 and sliding tapers 33 that slide on their tapered surfaces are used. 34 are fixed to four locations on the side surface of the table 32, and the four sliding tapers 33 are slidably connected to the inner surface of the base 31 and the fixed taper 34 via the fixed taper 34 and the feed screw 35, and the feed screw 35 It is attached to a motor 36 fixed to the sliding taper 33 so as to rotate in conjunction with the rotation of the motor shaft. Now, the first
As shown in Figure 3, move the sliding taper 33 in the direction in which the table 32 is to be slid from A.
When the sliding taper 33 is simultaneously moved from B to A' by the same amount at the same speed, the table 32 is moved from C to B'.
Slide to C′. Furthermore, in order to slide the table 32 in a direction perpendicular to this, as shown in FIG.
By simultaneously moving the sliding taper 33 in the sliding direction from D to D' and from E to E' by the same amount at the same speed, the table 32 slides from F to F'.

Furthermore, the following embodiment and its operating state diagram are shown in the 14th section.
Shown in Figures 15 and 16. This is because the sliding direction of the sliding taper 23 in the second embodiment of the present invention is perpendicular to both sliding directions of the table 22, and as shown in FIG.
A table 42 with a tapered side surface is supported within the table 1 through a taper slider 43. The taper slider 43 is attached to the side surface of the base 41 and the table 42.
The base 41 is slidable along both sides of the base 41 by a screw 44 that is connected to a motor 45 . Now, as shown in FIG. 16, if the taper slider 43 is moved from A to A' and from taper slider 43B to B' at the same time, at the same speed, and by the same amount, the table 42 will slide from C to C'. Of course, sliding the table in a direction perpendicular to this can be done in the same manner.

According to the present invention, since it is composed of only one base, one table, and two or four taper sliders, the structure is simple and the space required is small, and since the table is supported by the tapered structure, rigidity in the sliding direction is improved. It is possible to obtain a table sliding device that has advantages such as high resistance. Also, by preventing the table from separating from the base,
This sliding device has the advantage that it can be stably installed vertically.
