Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a ruler for positioning a saw blade of a circular saw type tenon remover and a marking line of wood.

[Conventional technology]

A conventional positioning ruler for a tenon remover will be described with reference to FIG.

Conventionally, wood (veneer plywood) has been used as the positioning ruler 10 of this type of tenon remover. The ruler 10 was attached to both inner sides of the vise plate 6, and the ruler 10 was used to hold wood. As for the alignment of the sharp line showing the cutting line on the wood and the horizontal saw blade 4, the tip of the ruler 10 is cut off, so the material of the ruler 10 is considered to be a machinable material, and veneer plywood has been used until now. It had been.

[Problems to be solved by the device]

When using a conventional mortise remover for a long time,
There arise problems such as misalignment of the core of the saw blade with the wood, misalignment of the horizontal saw blade 4 and the marking line.

This is because the ruler 10 is made of wood, and is damaged due to long-term use and deterioration due to corrosion. Due to the different consumption of the pair of left and right rulers 10, the wood and the horizontal saw blade 4 are misaligned with each other, and the tips of the ruler 10 are corroded to cause misalignment.

The purpose of the present invention is to eliminate the above-mentioned disadvantages of the prior art,
It is to prevent the positioning ruler from aging and maintain the positioning accuracy for a long time.

[Means for solving the problem]

According to the present invention, a resin ruler is fitted to the saw blade side of a pair of vise plates for sandwiching wood in a vise device, and is slidably and fixedly attached to the saw blade side.

[Action]

In the above configuration, first, in a state where the ruler is slightly moved from the position of the horizontal saw blade, the tip of the ruler is cut off by the horizontal saw blade to align the horizontal saw blade and the ruler.

Further, when the position of the horizontal saw blade is changed by polishing the edge of the vertical saw blade or the like, the position can be easily adjusted by slightly removing the ruler and cutting it off again.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a side view of a mortise picking machine showing an embodiment of the present invention, FIG. 2 is a plan view showing a vise device, and FIG. 3 is A- of FIG.
It is A sectional drawing.

In the figure, a vise device for holding a wooden piece 12 is provided at one end on a base 1, and a column 2 is vertically provided at the other end. The column 2 is fitted with a pair of orthogonal vertical saw blades 3 and horizontal saw blades 4 which are orthogonal to each other, and the cutting head 5 is vertically moved by an elevator device (not shown) to perform mortise processing. The vise device includes a pair of left and right vise plates 6,
A screw rod 7, which is screwed into the vise plate 6 with forward and reverse screws,
It is composed of a guide bar 8 for guiding sliding of the vice plate 6 and a handle 9 for rotating the screw rod 7.

The vise plate 6 is formed with a concave shape in a part of the holding surface of the wooden piece 12 on the side of the horizontal saw blade 4, and a ruler 10 made of plastic is fitted in the concave portion so that it can be moved back and forth toward the side of the horizontal saw blade 4. Mounting, a long hole is formed on the side surface of the vise plate 6, a knob bolt 11 is inserted into this long hole, and the ruler 10 is screw-fitted. The ruler 10 is fixed at an arbitrary position by tightening the knob bolt 11. The wood 12 holding surface of the ruler 10 and the vise plate 6 should be the same or slightly depressed from the ruler 10.

In the above configuration, the knob bolt 11 is loosened, and the ruler 10 is slightly moved from the position of the horizontal saw blade 4, and the tip of the ruler 10 is cut off by the horizontal saw blade 4 to remove the horizontal saw blade 4 and the ruler 10. Align.

Also, if the position of the horizontal saw blade 4 changes due to grinding of the vertical saw blade 3 or the like, loosen the knob bolt 11 and slightly expose the ruler 10 to the side of the horizontal saw blade, and then cut it off again for easy alignment. . In addition, since the ruler 10 surface is the same or slightly dented with respect to the vise plate 6 surface, the wood 12 is tightened on the vise plate 6 surface so that the wood 12 can be securely and accurately fixed, and the change of the ruler affects the positioning accuracy. I tried not to extend it.

[Effect of device]

According to the present invention, by embedding a resin ruler in the vise surface, it is possible to fix wood accurately and surely during long-term use, and it is possible to prevent misalignment due to deterioration of the ruler.
