Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drilling position setting device for a stationary woodworking drill for making a hole in the wood mouth surface.

[0002]

2. Description of the Related Art As a means for joining timbers, steel pipe joints are widely used in addition to conventional tenon joints. As shown in FIGS. 7 and 8, the steel pipe 31 is inserted into a hole 32 formed in a depth into which a half of the length of the steel pipe 31 is inserted at the center of the mouth end 30a of the one wood 30.
Hole 33 opened from the side of 0 and hole 31 formed in the steel pipe 31
Align with a, insert the bolt 34 there and insert the nut 35
And the steel pipe 31 is fixed to the wood 30. Moreover, the mortise 3 corresponding to the outer diameter of the steel pipe 31 is provided on the upper surface of the other wood 36.
7, a steel pipe 31 half-projected from the mouth end 30a of the wood 30 is inserted into this hole 37, a hole 38 opened from the side of the wood 36 and a hole 31b formed in the steel pipe 31 are aligned, and a bolt 39 is inserted therein. Is inserted and the nut 40 is tightened to join the timbers 30 and 36 to each other.

Among the above-mentioned joints, in order to make a hole 32 in the center of the mouth 30a of the wood 30, conventionally, a vertical and horizontal scribe line indicating the drilling position is drawn on the knuckle, and an electric drill is placed at the center of the scribe line. Measure the height of the wood using a stationary woodworking drill equipped with a vise device that fixes the wood to the base by drilling together the tips of the wood, or 1/2 position of the height. Was calculated to calculate the center position of the wood, and a drill unit was moved up and down to match the value to match the center of the wood for drilling.

[0004]

In the conventional method, in order to determine the hole position, it is necessary to draw a marking line, measure the height of the wood, and calculate the center position of the wood. It takes a lot of work, and if the calculation is incorrect, the hole position will shift,
There was a problem of wasting wood.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a stationary drill for woodworking in which the center position of the height of the wood can be set easily and accurately and the labor can be saved. Is.

[0006]

The above-mentioned object is aimed at a vise device for fixing lumber at one end on a base, and a slide frame provided with a drill unit movable up and down by a vertical moving means at the other end toward the vise device. In a movable woodworking stationary drill, a scale having a scale scale of 1/2 is erected on the slide frame, and the drill unit is provided with an indicator for indicating the scale.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view showing an embodiment of the present invention,
2 is a plan view of FIG. 1, FIG. 3 is a left side view of FIG. 1, FIG. 4 is an enlarged view of part A of FIG. 1, FIG. 5 is a front view showing a state where wood is fixed in FIG. 1, and FIG. It is a front view which shows the drilling operation in 1.

In the figure, a support 2 is fixed to the upper surface of a base 1, and a pair of guide rails 3 are fixed to the support 2 in the horizontal direction as viewed in FIG. A vise device 4 is fixed to one end of the guide rail 3. The vice device 4 has
By fixing the pair of guide bars 5 in the front-back direction as viewed from FIG.
A feed screw 6 is mounted between the guide bars 5, and threads 6a, 6a are formed on the left and right of the outer circumference of the feed screw 6 toward the center of each other. Vise plates 7 and 7 are screw-fitted to the screw threads 6a and 6a, respectively.
Guide bars 5 and 5 are inserted in the guide bar. A vise adjusting handle 8 for adjusting the opening of the vise plates 7, 7 is attached to one end of the feed screw 6, and when the vise adjusting handle 8 is rotated, the vise plates 7, 7 approach or leave each other via the feed screw 6. Move to. The centers of the vise plates 7 and 7 coincide with the center of the drill described later. A mounting surface 4 for the wood 30 is provided near the left end of the vise device 4.
A scale 9 having a scale scale 1/1 with a set to 0 is set up.

A slide frame 10 is fitted near the left end of the guide rail 3 so as to be movable in the left-right direction in FIG. 1, and one end of a left-right moving lever 11 extending obliquely upward in the base 1 is pivotally supported to form a left-right moving lever 11. A link 12 connects the slide frames 10 with each other. When the left-right movement lever 11 is moved left and right in FIG. 1, the slide frame 10 moves in the left-right direction via the link 12 with the guide rail 3 as a guide.

As shown in FIG. 3, the slide frame 10
Columns 13 and 13 are erected on the column, and a bridge 14 that connects the columns 13 and 13 to each other is fixed to the upper end of the column 13, and a drill 15 that horizontally protrudes in parallel with the guide rail 3 toward the vise device 4 is attached to the lower end of the column 13. , A drill unit 16 incorporating a motor (not shown) for rotating the drill 15 is attached.

The vertical moving means of the drill unit 16 will be described. A feed screw 17 located between the columns 13 and 13 penetrates the bridge 14, and a vertical movement handle 18 is fixed to one end of the bridge 14. When the vertical movement handle 18 is rotated, the feed screw 17 is used to rotate the drill unit 1.
6 goes up or down.

A scale 19 having a graduation scale of 1/2 is erected at a suitable position where it does not interfere with the vertical movement of the drill unit 16, and an indicator 20 indicating the scale 19 is attached at a suitable position of the drill unit 16.

In the above structure, the wood surface 30 of the wood 30
A method of forming the hole 32 in the center of a will be described. First,
The end of the wooden piece 30 is placed on the mounting surface 4a of the vise device 4, and the vise adjusting handle 8 is rotated to move the vise plates 7 and 7 toward each other to hold the wooden piece 30. Further, when the wooden piece 30 is fixed, the center of the drill 15 in the width direction of the wooden piece 30 is aligned with each other, so that the position adjustment of the wooden piece 30 in the width direction becomes unnecessary.

Next, the height of the wooden piece 30 is measured with the scale 9. For example, if the height of the wooden piece 30 is 90 mm, as shown in FIG. 5, the vertical movement handle 18 is turned to move the drill unit 16 up and down, and the position of the indicator 20 is changed to the scale indicating “90” on the scale 19. If combined, the center of the wood 30 in the height direction, that is, the height of the wood 30 is 45 m.
The center of the drill 15 is set at the position m.

By moving the left / right moving lever 11 to the right, as shown in FIG.
The drill unit 16 moves to the right with the guide rails 3, 3 as guides through the slide frame 10,
Press a drill 15 into a to make a hole.

[0016]

According to the present invention, since the scale graduation scale for setting the drill center position on the slide frame is halved,
The drill center can be easily and accurately aligned with the center of the wood height direction without calculating the center of the wood height direction. In addition, a scale with a scale of 1/1 is erected on the vise device, the height of the wood is measured using this scale, and the center position of the drill on the slide frame is determined according to the measured value. The drill position can be easily adjusted to the center position of the wood height without the need.
