Accordingly, the high-speed cutting machine capable of adjusting the horizontal angle according to the present invention having the configuration as described above may be easily rotated between the cutting head and the work table by selectively rotating the cutting head in the horizontal direction, thereby easily cutting the workpiece. In this regard, the series of usage relationships and their interactions are as follows.

Figure 3a and 3b is a cross-sectional view showing the operating state of the high-speed cutting machine capable of adjusting the horizontal angle according to the first embodiment of the present invention, Figure 4 is a high-speed cutting machine capable of adjusting the horizontal angle according to the first embodiment of the present invention Is a side view showing the state of use.

3 and 4, first, the workpiece of the small size is placed on the work table while holding the handle (H) and hinged the cutting head 20 in the vertical direction to rotate the cutting blade (C) to rotate the workpiece Cut.

On the other hand, in the case of a large workpiece that can not be placed on the worktable 10, the workpiece is placed on one side of the worktable 10 and rotates the cutting head 20 in the horizontal direction by using the handle (H). As such, when the handle H is rotated in the horizontal direction, the rotation shaft 143 and the angle adjuster 145 installed / fixed to the lower portion of the support bracket 141 rotate together with each other. At this time, the projection 144 of the angle adjuster 145 is initially located at the four corners of the installed leaf spring 149, and the rotation shaft 143 is rotated at the same time along the inner surface of the leaf spring 149. Rotate Here, in order to rotate the cutting head 20 in the horizontal direction, a force that is stronger than the elastic force of the leaf spring 149 is required, and the angle adjustor 145 rotated by such a strong force is the leaf spring 149 Each time the rotary head is rotated at an angle of 90 ° by the elastic force of the cutting head 20 to be rotated in the horizontal direction can be selectively adjusted at 90 ° angle.

In addition, when cutting the workpiece installed higher than the high speed cutter of the present invention, the work table 10 is positioned on the lift (R) to move up and down and then lift the work table 10 by using the fixing means 150 ( Fix to R). That is, when operating the switch (S) installed on the upper portion of the work table 10 to energize the coil, a magnetic field is generated in the electromagnet 152, the work table 10 is fixed to the ground of the lift (R). Thus, the high speed cutter is raised to the height of a workpiece | work in the state which fixed the worktable 10 to the lift R. Thereafter, the cutting head 20 is rotated in a horizontal direction so that the cutting head 20 protrudes to the outside of the work table 10, and the cutting head 20 is then cut.

Cutting work was possible, and the cutting machine was prevented from falling during the cutting work.

Hereinafter, with reference to the drawings will be described in detail a high-speed cutting machine capable of adjusting the horizontal angle according to a second embodiment of the present invention.

5a and 5b is a perspective view and a side configuration diagram showing a high-speed cutting machine capable of adjusting the horizontal angle according to a second embodiment of the present invention.

Here, the configuration of the cutting head, the rotating part and the work table is the same as the configuration of the high-speed cutting machine capable of adjusting the horizontal angle according to the first embodiment of the present invention. Therefore, the same configuration represents the same reference numerals, and description thereof will be omitted.

As shown in Figures 5a and 5b, the horizontal cutting machine is a high-speed cutting machine is a worktable 10 for fixing / supporting the workpiece; A cutting head 20 hinged to the work table 10 to cut a work piece; Driving unit 30 for providing a rotational force to the cutting blade (C) of the cutting head 20; It consists of a horizontal rotating unit 140 for rotating the cutting head 20 in the worktable 10 in the horizontal direction and a fixing means 150 for fixing / supporting the worktable 10 to the ground.

Here, the fixing means 150 is composed of an auxiliary support 251 and a support 253.

The auxiliary support 251 is hinged so that one side thereof is hinged in a horizontal direction on both sides of the work table 10, the support 253 is bolted to the other bottom. Accordingly, it is possible to adjust the height of the upper and lower through the rotation and reverse rotation of the support 253.

Thus, looking at a series of use relations and the corresponding interaction of the high-speed cutter capable of adjusting the horizontal direction according to the second embodiment of the present invention made as described above are as follows.

In the case of a workpiece having a large weight that cannot be placed on the workbench 10 during the cutting work, the cutting head 20 is rotated in the horizontal direction to perform the cutting work. In this case, the center of the pressing force of the high speed cutter is the workbench 10. The high speed cutter falls during the cutting operation while moving outward.

High-speed cutting machine capable of adjusting the horizontal angle according to the second embodiment of the present invention is to prevent such a phenomenon, when the cutting head 20 is rotated in the horizontal direction, the hinge is coupled to both sides of the work table (10) After the auxiliary pedestal 251 is hinged to protrude to one side of the workbench, the support 253 is rotated and reversely rotated to adjust the height of the ground. Accordingly, the auxiliary support 251 extends the length of the work table 10 to enable more stable cutting work.

The high-speed cutting machine capable of adjusting the horizontal angle of the present invention has a cutting head having a separate rotating part between a cutting head having a rotating cutting blade and a work table for fixing / supporting a work to perform a cutting operation. By selectively rotating in the horizontal direction on the workbench, there is an effect that it is easy to cut not only the limited size workpiece located on the workbench, but also the work placed outside the workbench and the structure higher than the height of the high speed cutter.

In addition, by installing a separate fixing means for preventing the high-speed cutter to collapse when pressurized to perform the cutting operation, the high-speed cutter is firmly fixed / supported from the ground to perform the cutting operation safely There is.
