Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a guard for preventing wood chips from scattering on a tabletop circular saw, which is equipped with an attachment for cutting the cut end of a rafter diagonally.

[Background of the idea]

In a hipped roof, there is a distributed daruki that connects to the corner tree. As shown in Fig. 6, the joint between the corner wood and the distributed dartboard is a cut that has slopes both upward and downward θ and both left and right α of the butt end, and cannot be processed using a tabletop circular saw alone. For this reason, I use a tabletop circular saw with a vise for wood processing.

At this time, as shown in Figure 1, in order to fix the material at a position away from the table of the tabletop circular saw,
When cutting, the piece of wood on the cut-off side fell onto the table, and the piece of wood that fell on the circular saw side came into contact with the circular saw, causing the piece of wood to get caught up in the circular saw and fly off, causing injuries. .

[Purpose of invention]

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks and improve safety when processing distributed wood by preventing falling pieces of wood from getting caught in the saw blade. .

[Summary of the idea]

This invention focuses on the fact that the cut-off piece of wood does not fall toward the circular saw, and installs a guard with an inclined tip near the circular saw on the material cutting side of the circular saw. The saw was designed to prevent wood chips from scattering.

[Example of idea]

An embodiment of the present invention will be described using FIGS. 1 to 6.

The table 1 is provided with a sliding part 1', a turntable 2 is rotatably fitted into the sliding part 1', and a hinge 3 is fixed to the turntable 2 with bolts 4. The hinge 3 has a handle 5 for fixing the rotation of the turntable 2, and a motor portion 6 is slidably supported on the hinge 3 via a hinge shaft 7. The motor part 6 includes a circular saw 8 and a handle 9 for swinging the circular saw 8.
is installed. Further, a fixed vise is fixed to the table 1.

Next, the rafter processing vise section will be explained.
The base 11 is fixed to a fixed vise 10 with thumbscrews 12, and a sub-base 13 is pivotally supported to be able to swing freely using the base 11 as a fulcrum.
5 is installed. Knob 16 is sub-bass 1
This is to fix the swinging of No. 3. The knob 17 has the role of finely adjusting the rocking of the sub-base 13 and the role of preventing the sub-base 13 from falling.

Further, a card 18 is fixed onto the turntable 2 with screws 19.

In the above configuration, the turntable 2 is rotated according to the required inclination of the cutting surface, and the sub-base 1 is
After setting the swing angle of 3, the material 20 is fixed to the sub-base 13 with the vice plate 15.

The angle of this turntable 2 and the sub base 1
By performing the swinging step 3, the cut end of the distributed dartboard has slopes both upward and downward θ and left and right α.

Further, the other end of the distributed dartboard is cut vertically, and in this case, the turntable 2 performs the vertical cutting without changing the angle.

At this time, the guard 18 is attached to the cut-off side of the material 20. In FIG. 2, part A of the material 20 is fixed to the sub-base 14, and part B shows the cut-off side.

Next, the handle 9 is lowered to cut. The cut off piece of wood 21 hits the guard 18 as shown by the arrow in FIG. 5 and falls onto the turntable 2. Since the upper part of the guard 18 is sloped, the piece of wood 21 does not remain on the guard 18.

In addition, the vise device shown by the dashed line in FIGS. 2 and 3 is installed on the right side of the tabletop circular saw. At this time, the guard 18 is attached to the opposite side of the turntable 2 by loosening the screw 19. It can be moved and fixed.

[Effect of idea]

As described above, according to the present invention, a guard with an inclined tip is provided on the turntable to prevent cut-off pieces of wood from coming into contact with the circular saw.
It is possible to prevent the cut pieces of wood from coming into contact with the circular saw, it is possible to prevent the pieces of wood from getting caught up in the circular saw and being scattered, and it is possible to improve safety during the distribution barrel wood processing operation.

[Brief explanation of the drawing]

Fig. 1 is a side view of a tabletop circular saw equipped with a guard to prevent wood chips from scattering, showing an embodiment of the present invention; Fig. 2 is a front view of Fig. 1; Fig. 3 is a plan view of Fig. 1;
The motor and hinge part of the tabletop circular saw part are omitted in Figures 3 and 3. ) Figure 4 is a perspective view of the turntable rotated for processing the distributed dartboard, Figure 5 is an enlarged view of the guard section, and Figure 6 shows the end of the distributed dartboard. , α, θ
It has both slopes, and in FIG. 6, a shows a plan view and b shows a front view. In the figure, 1 is a table, 8 is a circular saw, 18
is a guard, 19 is a screw, and 20 is a material.
