BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a router used for processing wooden dishes and the like.

[0002]

2. Description of the Related Art A wood milling machine called a router, which is provided with a vertical rotary spindle above a table that can be moved up and down, and a cutter is attached to the lower end of the rotary spindle to cut wood on the table, has been widely known. Since this router has a structure in which the table and rotating main shaft cannot move horizontally, it is necessary to move the work on the table to process the wood, and the operator should bring his hand close to the cutter that rotates at high speed. There was a problem that it was dangerous because it had to be done.

[0003]

The present invention has been completed to solve the above-mentioned conventional problems and provide a router capable of safely processing wood.

[0004]

SUMMARY OF THE INVENTION The present invention, which has been made to solve the above-mentioned problems, provides a rotary spindle equipped with a cutter above a table that can be moved up and down , and mounts a bracket on the upper surface of a corner portion of the table. through height adjustably secure the arms extending parallel to the machining position and the table surface,
An annular protector surrounding the cutter lowered to the processing position is attached to the tip of the arm.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. In FIGS. 1 and 2, 1 is a table that can be raised and lowered by operating a foot-operated pedal or the like, 2 is a fixed head provided above the table 1, and 3 is vertically supported by the head 2. The rotating spindle 4, which is rotated at high speed, has a chuck 5 at the lower end of the rotating spindle 3.
It is a milling type cutter fixed by.

In the present invention, the arm 7 is fixed to the bracket 6 on the upper surface of the table 1. The arm 7 is an elongated member extending parallel to the table surface, and is attached to the longitudinal slot 8 of the bracket 6 so that the height can be adjusted to some extent. An annular protector 9 is attached to the tip of the arm 7.

As shown in the drawing, the ring-shaped protector 9 is at the processing position.
It is a wooden piece having a size surrounding the lowered cutter 4, and has a structure in which the cutter 4 can process a work through a through hole 10 in the center thereof. It goes without saying that the protector 9 can also be replaced depending on the type of the cutter 4.

[0008]

In the router of the present invention thus constructed, the table 1 is lowered and a work piece of wood is placed on the upper surface of the table 1, and the work piece is positioned on the table 1 immediately below the cutter 4 and then placed on the table. It is the same as the conventional router that 1 is raised and a wooden plate or the like is processed by the rotating cutter 4. However, in the present invention, since the protector 9 is attached to the tip of the arm 7 at the processing position, when the table 1 is raised , the fingers should not be in the processing position.
To reliably prevent the insert on the axis of KazuSatoshi cutter 4
The cutter 4 that has reached the processing position will hurt your fingers.
You won't get kicked. The cutter 4 is that Do and be in contact with the workpiece through a central through hole 10 of the protection 9
However , at this time, the periphery of the cutter 4 is processed while being completely protected by the protector 9 . Therefore, in the router of the present invention, even when the work is moved by the worker's hand, there is no risk of the worker's hand touching the rotating cutter 4, and the wood pieces scattered from the cutter 4 hit the worker's hand. Without any work, you can work safely.

The protector 9 is located on the corner of the table 1.
Since it is fixed to the end of the arm 7 extending parallel to the table surface via the bracket 6 in a height adjustable manner ,
Since the height can be changed according to the thickness of the work, there is no obstacle when moving the work on the table 1,
Further, since the protector 9 can be raised and lowered simultaneously with the table 1, the gap between the protector 9 and the table 1 is always kept constant, and the work can be freely moved. Also, protector 9 is always in the processing position.
Therefore, before processing, lower the cutter 4 once to the processing position.
There is no need to make arrangements.

[0010]

As described in detail above, in the router of the present invention, an arm extending parallel to the table surface is fixed to the upper surface of the table, and the tip of this arm is used to move the cutter down to the processing position . By attaching a ring-shaped protector that surrounds the circumference , the fingers enter the processing position and the fingers are damaged.
In addition, there is an advantage in that it is possible to accurately prevent the operator's fingers from touching the cutter that rotates at high speed during processing, and to eliminate the risk of working . Therefore, the present invention is of great practical value as it solves the problems of the conventional router.
