DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mortise cutting auxiliary stand which can accurately perform mortise cutting in a mortise cutting machine for wood or the like.

[0002]

2. Description of the Related Art In a conventionally proposed mortise cutting auxiliary stand, a roller receiver is provided laterally on the upper end of a column,
A roller is axially supported in parallel with the roller receiver.

[0003]

In the conventional mortise cutting auxiliary stand of the conventional mortise cutting machine, wood is placed on the roller receiver to perform mortise cutting toward the mortise cutting machine. In this case, since the roller bridge is horizontal, it is difficult to standardize the mortise due to the left and right movement of the wood, and the person who operates the wood always pays close attention to the movement of the wood on the roller. There are issues of labor and effort that must be made.

Therefore, the present invention has an object to prevent the shaking of the wood when the mortise is cut, and further, the mortise cutting is accurately performed and standardized, and the time and labor are saved. The purpose is to provide a mortise cutting assist stand.

[0005]

In order to achieve the above-mentioned object, the mortise cutting auxiliary stand of the present invention has two elastic rollers arranged at right angles in a rotatable mounting tool at the upper end of a column. It is rotatably supported on the mounting part.

[0006]

[Function] The square timber is placed on the roller of the mortise cutting auxiliary stand configured as described above and slidably contacted with the vertical roller on the side surface, and the tip of the square timber is directed in the direction of the mortise cutting machine,
When sticking out due to transfer of rollers ▲ Mortice ▼ By cutting machine ▲
Mortise is cut.

When the mortise on the opposite side of the timber is to be cut, the attachment of the auxiliary mortise-cutting stand should be turned along with the timber, and the timber should be trimmed in the same manner as the above operation. You can

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

In the embodiment shown in FIGS. 1 and 2, columns are planted on the base 1. The support pillar is divided into two parts vertically, and the upper support pillar 2b is inserted into the lower support pillar 2a so as to be vertically expandable and contractable, and fixed by the lever 3 attached to the side surface of the lower support pillar 2a. At the upper end of the upper strut 2b, recesses 5a and 5b are provided on the left and right outer surfaces of the fixture 4 so that the fixture 4 can rotate, and the support 7 of the upper strut 2b is provided in the recesses 5a and 5b. The projections 6a and 6b on the left and right inner surfaces of the are fitted and slid.

In order to rotate the fixture 4, as shown in FIG.
It is also conceivable to project 16b and insert the projections 16a and 16b into the recesses 17a and 17b provided on the left and right side surfaces of the upper end of the upper support column 2b and slide them.

The mounting member 4 has both ends bent inward to form mounting portions 8a and 8c. Insert holes 9a and 9d are provided in the inner surfaces of the mounting portions 8a and 8c, respectively.
Attachment portions 8b are formed at one end of the fixture 4 on the inner surface at a position on a horizontal line and at the other end at an inner surface at a position on a vertical line, and insertion holes 9b, 9c are formed on the upper surface and side surfaces of the attachment 8b.
Is provided. Insert the shaft portion 11a of the elastic roller 10 into the insertion hole 9a.
Then, the shaft 11b is inserted vertically into the insertion hole 9b, the shaft 13a of the elastic roller 12 is inserted horizontally into the insertion hole 9c, and the shaft 13b is inserted horizontally into the insertion hole 9d.
0 and 12 are formed to be rotatable at right angles. The attachment 4 is preferably arc-shaped.

The stopper 14 fixes the position of the fixture 4.

In the embodiment of the present invention, recesses are provided on the left and right outer surfaces of the fixture so that the fixture can rotate, and the projections on the left and right inner surfaces of the support portion of the upper column are provided in the recesses. As an example, let it be slid by inserting it, and projecting protrusions on both inner sides of the hollow fixture and inserting the protrusions into the recesses on the left and right side surfaces of the upper end of the upper strut to slide. As described above, the present invention is not limited to this, and it suffices that the fixture can rotate.

[0014]

Since the present invention is constructed as described above, it has the following effects.

Since the mortise cutting auxiliary stand is small, it can be moved freely and easily.

Since the elastic roller is pivotally supported in the fixture at right angles, the movement of the square members is light, and since they are also arranged at right angles, they can be moved straight by the rolling of both rollers and there is no misalignment in position.

Since there is no need to always hold the timber, it is possible to save labor and time.

ほ Mortise 切 り Can be cut accurately.
