And slide bar 4 above holder 3 as base 1
Is held parallel to the upper surface of the slide bar and slidably in the front-rear direction, and the rotary blade holder 5 is connected to the front end of the slide bar 4.
And the hinge shaft 7 is inserted in parallel with the upper surface of the base 1,
Rotary blade part 10 with hinge shaft 7 as axis and base 1
The rotary blade portion 10 is provided with a rotary blade 13, a motor 12 for driving the rotary blade 13 to rotate, a switch 15 for driving the motor 12, and a handle 14.

When cutting the work 16, as shown in FIG. 6, the work 16 is supported on the upper surface of the base 1 and the side of the fence 2 fixed to the base 1, and the rotary blade 10 is kept at the upper limit position. Slide bar 4 forward (handle 14 side)
After pushing down the handle 14 to give a cut,
As shown in FIG. 7, while the rotary blade 10 is being pushed down, the rotary blade 10 is pushed to the far side (the holder 3 side) with the handle 14.
Cut while sliding.

[0005]

In the above-mentioned conventional apparatus, the rotary blade portion 1 is formed on a plane parallel to the upper surface of the base 1.
If the rotary blade 13 is inclined with respect to the front / rear sliding direction, the cutting resistance of the slide cutting process increases, or the cutting is performed obliquely with respect to the sliding direction. There was a problem that had to be done.

An object of the present invention is to provide a mechanism capable of adjusting the angle of a rotary blade with respect to the sliding direction of the rotary blade in the front-rear direction.

[0007]

The object of the present invention is to provide a base on which an object to be cut is placed on an upper surface, a holder provided behind the base, a slide bar held slidably above and below the holder. A rotary blade holder disposed at the front end of the slide bar, and a hinge shaft inserted through and supported by the rotary blade holder, and placed parallel to the upper surface of the base;
In a rotary tabletop cutting machine having a rotary blade portion that is supported swingably up and down with the hinge shaft as a support shaft, and a motor that drives a rotary blade provided in the rotary blade portion, the hinge shaft is disposed on an upper surface of a base. This is achieved by pivotally supporting a pin provided on the rotary blade holder so that it can be adjusted and moved in parallel and in the front-rear direction, and can be fixed at the adjusted position.

[0008]

1 to 5 show an embodiment of the present invention.
It will be described based on.

In FIG. 1, a work material 1 is provided on an upper surface of a base 1.
The fence 2 supporting 6 is fixed. The holder 3 is connected to the rear end of the base 1. Two through holes (not shown) parallel to the upper surface of the base 1 are formed above the holder 3, and a slide holding member (not shown) is provided in the through hole. The two slide bars 4 are respectively inserted.

The slide bar 4 is slid parallel to the upper surface of the base 1 and back and forth by the slide holding member. A rotary blade holder 5 is provided at the front end of the slide bar 4, and a support 6 for preventing the slide bar 4 from coming off is provided at the rear end.

As shown in FIGS. 2 and 3, elongated holes 5a and 5b are provided at both ends of the rotary blade holder 5 in the sliding direction of the slide bar 4, and hinge shafts 7 are provided in the elongated holes 5a and 5b. It is inserted. One end of the hinge shaft 7 is rotatably supported by a pin 8 penetrating above and below the long hole 5b of the rotary blade holder 5, and the other end is in the front-rear direction of the other long hole 5a of the rotary blade holder 5. It is held or fixed by a set screw 9 (fixing means) fitted with a screw. The rotary blade portion 10 is supported by a hinge shaft 7 so as to be vertically swingable with respect to the upper surface of the base 1, and is urged upward by a spring 11.

The rotary blade unit 10 includes a motor 12, a rotary blade 13 such as a saw blade, a handle 14 for pushing down the rotary blade unit 10, and a switch 15 for driving the motor 12.

In the above configuration, when the push screw 9 screwed into the rotary blade holder 5 is moved in a direction away from the hinge shaft 7 as shown in FIG. One can rotate parallel to the upper surface. By rotating the hinge shaft 7, the slide bar 4
Then, the push screw 9 is brought into contact with the hinge shaft 7 to fix the hinge shaft 7 as shown in FIG. In this state, the direction in which the rotary blade 10 slides and the rotary blade 13 are kept parallel.

When cutting a wide work material, the work material 16 is pressed against the surface of the fence 2 and is fixed. Then, the work material 16 is pulled forward by the handle 14, and the rotary blade holder 5, the support 6, the slide bar 4 and The rotary blade unit 10 moves forward integrally. Next, when the switch 15 is pressed, the motor 12 is driven to rotate the rotary blade 13. After the handle 14 is depressed to give a cut, the cutting is performed while sliding the rotary blade 10 backward.

[0015]

According to the present invention, the hinge shaft can be rotated, adjusted and moved to a predetermined position and fixed, so that the sliding direction of the sliding member and the rotary blade can be adjusted without depending on the processing accuracy of the parts. Can be held in parallel, so that processing can be facilitated and inexpensive parts can be provided.
