Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone processing machine used for cutting a stone along an arbitrary surface.

[0002]

2. Description of the Related Art Among conventional stone processing machines, the cutting blade head has 9 heads.
Although there is a type in which the cutting direction can be changed by rotating it in the 0 degree direction, the center of rotation of the cutting blade is at a position different from the axis of the turning spindle.

[0003]

When making an anvil having a complicated curved surface, it is necessary to change the relative position and the relative angle between the cutting edge and the stone material in various ways. It is general that a model product is created and the model product is copied and processed. It is an object of the present invention to provide a stone material processing machine which does not rely on such copying, that is, which enables direct processing.

[0004]

In order to achieve the above object, according to the present invention, a cutting edge rotatably driven through a main shaft has a rotating surface at the tip of a swivel support shaft which is freely driven around a shaft center. It is characterized in that it is arranged so as to include the shaft core and its rotation center is located on the coaxial core. This cutting edge is designed so that it can be driven and displaced in the directions of the three orthogonal axes, and a carriage that can be driven and displaced in a fixed direction is provided at a location facing the cutting blade, and the carriage has a power around a fixed axis. It is preferable to provide a swingable tilting table and a stone fixing table that can be driven to rotate around a fixed axis on the table.

[0005]

[Operation] Even if the turning spindle is swung as necessary to displace the cutting edge, the cutting edge is displaced so as to rotate around the axis of the swivel spindle as the center of rotation and its center position is not displaced. This reduces the operation of each part of the machine at the time of positioning, and allows relatively easy positioning at any position. That is, the position control of the cutting edge is simplified, and the curved surface cutting of the cutting object can be performed without causing unnecessary movement. Further, by appropriately displacing the cutting blade and the stone on the stone fixing table appropriately by the electronic control device, it is possible to rationally manufacture any annealed product by the copying process or not, and in addition to the specific process. The product can be processed extremely easily.

It will be processed quickly. The input information to the electronic control device may be numerical control information processed by a computer, or copying information previously obtained by another copying device. In the machining of a stone material of a turning material, the cutting blade 36 is frequently swung and displaced in its direction by turning of the turning support shaft 25 depending on the shape of the turning work. The rotation center c of the cutting blade 36 does not move at all due to the rotation displacement around the core g.

When manufacturing an anvil having a spherical hole r as shown in FIG. 5A, the stone fixing table 5 is used.
On the upper surface of the stone material w on 7, the cutting blade 36 rotated by the main shaft motor 33 is rotated around the rotation support shaft 25 and the motor 19 is rotated to gradually move the upper and lower saddles 18 downward. Further, when manufacturing an anvil having a spiral groove s on the outer surface as shown in FIG. 2B, the stone w on the stone fixing table 57 is tilted as shown in FIG. In addition, the rotation surface of the cutting blade 36 is directed so as to intersect with the direction of the spiral groove s, and then the stone fixing table 57 is rotated by the rotation of the motor 59 while the cutting blade 36 and the stone material w are appropriately displaced relative to each other. Be seen.

As described above, according to the present invention, since the cutting edge can be driven and displaced in the directions of the three orthogonal axes, it becomes possible to quickly and easily process a stone object or a stone material having a complicated shape. In addition, since it does not require a model as in the copying method, it greatly contributes to reduction of manufacturing cost and improvement of work performance.
