JPS585042B2 - 3D centering table - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a centering table that can arbitrarily adjust each three-dimensional inclination angle.

It is often desired to perform a predetermined scribing operation on a three-dimensional surface with an extremely complex shape.

For example, a shoe mold used in shoe manufacturing is a suitable example.

As is well known, the dimensional regulations for shoes usually have restrictions on the direction of the scribing lines that serve as the standard for dimensions, but when attempting to draw scribing lines on the surface of a shoe last that comply with these constraints, Even if this was done using a conventional two-dimensional centering table, the repetition would be extremely complicated;
Moreover, the results obtained were of low precision, making it impossible to achieve satisfactory results.

The object of the present invention is to provide a centering table that can perform various three-dimensional operations on solid objects with high efficiency, extremely simply, and with high accuracy, including the above-mentioned cases. It was done for a purpose.

The structure of the three-dimensional centering table according to the present invention will be explained with reference to the drawings showing the embodiments. In FIG.
1 is a plywood board, approximately at the center of which the horizontal axis
Tilting about the horizontal axis X is supported.

The base plate 3 is provided with a pair of bearings 2, 2 for supporting the horizontal axis (visible) allows tilting movement around it to be supported.

The bolts 8.8 have a length that passes through screw holes drilled in staggered positions on the base plate 1 so that their tips reach the base plate 3, and the screwing length of the bolts 8,8 By adjusting the angle, it functions as a jacking device for arbitrarily adjusting the inclination angle of the base plate 1 on the base plate 3.

The base plate 5 has a shape that combines two orthogonal surfaces, that is, a horizontal surface and a vertical surface, and the portion that constitutes the horizontal surface is provided with bearings 4, 4 for supporting the horizontal axes Y, Y, and the vertical surface The parts constituting the are provided with vertical axes Z and Z, and the base plate 5
can be assembled so as to be tiltable about the vertical axis Z, Z.

9.9 (only one is visible in the diagram) is the base plate 3
It is provided in a staggered arrangement position on the top, and its tip is connected to the base plate 5.
It reaches the upper surface of the bolts 8, 8, and functions as a jacking device for setting the base plate 3 at an arbitrary inclination angle with respect to the base plate 5, similarly to the bolts 8,8.

The base plate 7 has a shape in which two orthogonal vertical surfaces are combined, and is provided with bearing parts 6, 6 for supporting the vertical axes Z, Z.

The inclination angle of the base plate 5 with respect to the base plate 7 can be arbitrarily adjusted by adjusting the screwing length of the bolts 10, 10 as a jacking device, as in the case of each of the bolts described above.

In the above explanation, the terms horizontal or vertical force were used in the direction of the orthogonal planes and the directions of each axis constituting each of the base plate 5 and the base plate 7, but these expressions both apply to the first This merely represents the directional relationship in the state shown in the figure, that is, the state in which the smooth surface 5a of the base plate 5 is left standing as the ground surface.
It goes without saying that the above expression does not necessarily apply if the ground plane is left standing with a or 7b as the ground plane.

Now, in Fig. 1, for the shaft pattern A shown by the dashed-dotted line screwed onto the top surface of the base plate 1, a line parallel to the line connecting the center of the toe of the sole and the center of the heel is drawn on its surface. When you are trying to make a score line, or when you are trying to make a line parallel to the vertical line B on the back of the wooden shaft pattern A on its surface, press each base plate 1, 3゜5 of this device, respectively. It is clear that the inclination angle can be adjusted by means of bolts disposed on the surface, and the above-mentioned markings can be easily performed using a dosing can.

As described above, according to the three-dimensional centering table of the present invention, work such as marking in three-dimensional directions on a three-dimensional object can be performed with high efficiency, extremely simply, and with high precision. , exhibiting unprecedented effects.

Note that FIG. 2 shows a different embodiment, and in the example shown, the bearing part 2
This shows an example in which the aspect of the bearing portion 4 is different from the example in FIG. 1, but the principle and other configurations are not different from the example in FIG.
