The auxiliary rotation shaft 341 is elongated in the horizontal direction in the form of a cylinder having a predetermined diameter. As shown in the figure, the left end of the auxiliary rotary shaft 341 is supported by being coupled by the main rotary shaft 332 and the bolt, the left end of the auxiliary rotary shaft 341 is tapered the diameter decreases toward the left Is formed in the form, to facilitate the coupling with the main shaft 332.

In detail, when viewed from the drawing, the right side surface of the main rotating shaft 332 is formed to have a substantially "⊂" shape, the surface formed to be recessed toward the left side is formed to reduce the cross-sectional area toward the left side. That is, the recessed surface is tapered while having a predetermined slope.

In addition, the left end of the auxiliary rotary shaft 341 is tapered to protrude to the left to have a shape corresponding to the recessed portion formed on the right side of the main rotary shaft 332.

As such, the left end of the auxiliary rotary shaft 341 is inserted into the right side of the main rotary shaft 332 having a shape corresponding to each other, and the center of rotation of the main rotary shaft 332 and the auxiliary rotary shaft 341 according to the inclination thereof. It can be located on this virtual same line.

When the left end of the auxiliary rotary shaft 341 is inserted into the right side of the main rotary shaft 332, the fastening bolt penetrating the auxiliary rotary shaft 341 in the left and right directions is fastened with the main rotary shaft 332. The auxiliary rotation shaft 341 is coupled.

The auxiliary bearing part 342 is positioned outside the auxiliary rotary shaft 341. The auxiliary bearing part 342 has a configuration including an auxiliary bearing 343 supporting the auxiliary rotating shaft 341 and a bearing housing 344 in which the auxiliary bearing 343 is accommodated.

The auxiliary bearing 343 may be any type of bearing capable of supporting the auxiliary rotating shaft 341. In the embodiment of the present invention will be described for example a tapered roller bearing having a certain degree of inclination.

The bearing housing 344 is formed to have a cylindrical shape having a predetermined internal space in the horizontal direction, and the auxiliary rotation shaft 341 penetrates the horizontal space in the internal space.

An auxiliary bearing 343 supporting the auxiliary rotating shaft 341 is positioned between the inner surface of the bearing housing 344 and the auxiliary rotating shaft 341. The auxiliary rotation shaft 341 is supported by the auxiliary bearing 343 while rotating.

An outer housing 345 surrounding the bearing housing 344 is mounted outside the bearing housing 344. The auxiliary housing 345 is formed long in the horizontal direction in the form of a cylinder having a predetermined internal space.

In this case, a space is formed between the bearing housing 344 and the auxiliary housing 345, and a fluid supplied at a constant pressure is filled in the space. The fluid is supplied at a constant pressure from the fluid supply unit 40, which will be described later, and configured such that oil or air such as hydraulic oil or pressure oil can be used.

Of course, a configuration using a fluid other than pressure oil or air may be possible. However, a configuration in which a fluid capable of withstanding strong pressure and weight will be used will be preferable. In the embodiment of the present invention, a configuration in which working oil is used will be described as an example.

The fluid supply unit 40 includes a fluid tank 41 for storing the fluid, a cylinder 42 for pressurizing the fluid supplied from the fluid tank 41 to a predetermined pressure, and the cylinder 42. And a fluid guide part 43 for guiding the fluid pressurized by the cutting unit 30.

In the embodiment of the present invention will be described by way of example a configuration in which the fluid pressurized by the fluid supply unit 40 is pressurized by pneumatic pressure and then by hydraulic pressure. Of course, a configuration that is pressurized by either pneumatic or hydraulic may be possible.

The fluid contained in the fluid tank 41 is pressurized by pneumatic pressure, the fluid moved to the cylinder 42 has a configuration that is pressurized by hydraulic pressure.

The fluid tank 41 is equipped with a pneumatic cylinder 411 to pressurize the fluid contained in the inner space of the fluid tank 41 at a pressure of approximately 5kg / ㎠ by air. The fluid pressurized by the pneumatic cylinder 411 flows to the cylinder 42.

The fluid flowing into the cylinder 42 is pressurized by hydraulic pressure in the inner space of the cylinder 42. At this time, the pressure for pressurizing the fluid is approximately 80㎏ / ㎠, the fluid pressurized at a pressure of approximately 80㎏ / ㎠ flows into the internal space of the cutting unit 30, in detail the auxiliary rotating part 34 The bearing housing 344 is supported at a constant pressure in all directions.

As such, while supporting the bearing housing 344 at a constant pressure in all directions, the rotation center of the auxiliary rotation shaft 341 and the rotation center of the main rotation shaft 332 are located on the same virtual straight line. .

Specifically, when the auxiliary rotating part 34 is separated from the main rotating part 33 and then recombined, the auxiliary rotating part 34 is supported by the fluid having a constant pressure in all directions.

In other words, after replacing the auxiliary rotary part 34 with the main rotating shaft 332 by removing the auxiliary rotating part 34 to replace, repair, or repair the cutting tool 335, the cutting tool 335 may be replaced or repaired. When the repair is completed, the cutting tool 335 is mounted on the main shaft 332.

When the cutting tool 335 is mounted on the main rotating shaft 332, the auxiliary rotating shaft 341 is coupled to the main rotating shaft 332. At this time, the auxiliary rotation shaft 341 is supported by a constant pressure along the outer circumferential surface by the fluid of high pressure, so that the rotation center of the main rotation shaft 332 and the rotation center of the auxiliary rotation shaft 341 lie on the same line.

Since the rotation center of the main rotation shaft 332 and the rotation center of the auxiliary rotation shaft 341 lie on the same line, the main rotation shaft 332 has a certain rotation center and has an advantage of rotating.

The outer surface of the auxiliary housing 345 is formed with a fluid inlet 347 that provides a passage for the fluid supplied from the fluid supply unit 40 flows into the inner space of the auxiliary housing 345.

The fluid inlet 347 is formed in a shape that the internal space is empty while having a predetermined diameter. One end portion of the fluid inlet 347 communicates with a space between the bearing housing 344 and the auxiliary housing 345, and the other end portion is connected to the fluid supply unit 40.

Referring to Figure 5, the space between the bearing housing 344 and the auxiliary housing 345 is equipped with a plurality of airtight member 346 to prevent the external leakage of the fluid supplied. The airtight member 346 is well formed to withstand high pressure, and formed of a material having excellent strength.

The fluid flow part 348 for the flow of the fluid is formed on the outer surface of the bearing housing 344 adjacent to the airtight member 346 positioned in the longitudinal center portion of the bearing housing 344.

The fluid flow part 348 is to allow the fluid flowing through the fluid inlet 347 to flow through the entire space between the bearing housing 344 and the auxiliary housing 345.

Specifically, the longitudinal flow of the bearing housing 344 of the fluid introduced through the fluid inlet 347 by the hermetic member 346 located in the longitudinal center portion of the bearing housing 344 Are interfering.

The fluid flow part 348 is formed on the outer surface of the bearing housing 344 so that the fluid introduced therein is not interfered by the airtight member 346 and flows in the longitudinal direction of the bearing housing 344. do.

The fluid flow part 348 forms a hole in the outer surface of the bearing housing 344 to the left and right of the airtight member 346, and forms a passage for communicating the hole so that the fluid flow part 348 is formed. Is formed.

Of course, the fluid flow portion 348 may be configured to be recessed toward the center portion of the bearing housing 344 in the form of a groove rather than a hole. In the embodiment of the present invention to look at the configuration in which the airtight member 346 is mounted to the left, middle, right three, for example, the fluid flow portion 348 is a configuration that is processed in the form of a hole, for example Let's look at it.

That is, in the space between the bearing housing 344 and the sub-housing 345, the airtight member 346 is located at the left side of the sub-bearing part 342, and at the central part of the sub-bearing part 342. The hermetic member 346 is located, and is configured such that another hermetic member 346 is located at the right side of the auxiliary bearing part 342.

In addition, the fluid flow part 348 is formed only at a lower portion of the airtight member 346 positioned at the central portion in the longitudinal direction of the bearing housing 344. This is because the airtight members 346 respectively mounted on the left and right portions of the bearing housing 344 are mounted to prevent leakage of the fluid, so that the formation of the fluid flow portion 348 is unnecessary.

The space between the bearing housing 344 and the auxiliary housing 345 by the fluid flow unit 348 is configured to allow the flow of the fluid as a whole.

On the other hand, when the fluid is entirely filled in the space between the bearing housing 344 and the auxiliary housing 345, the fluid has a pressure of approximately 80kg / ㎠ while the bearing housing 344 in the entire circumferential direction Will be supported.

In the embodiment of the present invention has been described for example the configuration in which the fluid supports the bearing housing 344 while having a pressure of 80 ㎏ / ㎠, which is according to the overall size or rotational force of the auxiliary rotating part 34, etc. It can be adjusted and used properly.

According to the multi-leaf stone cutting machine according to the present invention, the rotational center of the main rotary shaft and the auxiliary rotary shaft is located on the same line by the pressure of the fluid, the main rotary shaft is configured to rotate with a constant rotation center.

The main rotary shaft has the advantage that the cutting tool mounted on the main rotary shaft has the same height to rotate the rotary motion with a constant rotation center, the stone is cut constantly.

In addition, corrosion is prevented by preventing the penetration of moisture by the fluid supporting the auxiliary rotating shaft, and the fluid absorbs the vibration of the auxiliary rotating part, and thus, the damage and the noise of the auxiliary rotating part due to the vibration are prevented.

Due to these various advantages and advantages, the multi-leaf stone cutting machine according to the present invention will have great applicability not only in the stone processing industry but also in various industries related to the stone cutting machine.
