DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is generally applied to not only a cut material having a rectangular cross section (hereinafter referred to as a rectangular material) but also a decorative long pressing material (crown molding material: attached along a corner between a ceiling and a wall). The present invention relates to a vice device for a tabletop circular saw suitable for cutting a decorative long pressing material having an attachment angle θ to a ceiling of 38 degrees to 45 degrees.

[0002]

2. Description of the Related Art A tabletop circular saw for cutting such a crown material is disclosed in US Pat. No. 4,875,399. This provides a stopper that supports the front end of the crown material on the anti-fence side, positions the stopper on the upper surface of the base when cutting the crown material, supports the crown material, and retracts the stopper from the upper surface of the base when cutting a normal rectangular material. It is like that.

[0003]

To apply the USP configuration to an existing tabletop circular saw, considerable modification is required.
There was a problem that it could not be easily applied.

An object of the present invention is to provide a vice device which can stably support a crown material and can be easily applied to an existing tabletop circular saw.

[0005]

The object of the present invention is to provide a vise holder comprising a first member fitted to a vise shaft and extending in a direction parallel to a base portion, and a second member to which a vice attachment body is attached so as to be able to advance and retreat. This is achieved by attaching the second member to the first member so that the attachment angle is variable.

[0006]

1 to 6 show an embodiment of the present invention.
This will be described with reference to FIG.

A turntable 2 is embedded in the center of the base 1 so as to be rotatable in the horizontal direction. The upper surface of the turntable 2 is flush with the upper surface of the base 1. A material to be cut such as a crown material 21 or a rectangular material 30 is placed on the upper surfaces of the base 1 and the turntable 2. In the present invention, the member on which the material to be cut is placed (the base 1 in this embodiment).
And the turntable 2) are collectively called a base part. A fence 3 that supports an end surface of the material to be cut is fixed to the upper surface of the base 1.

At the rear end of the turntable 2, a holder 5 is provided upright via a holder shaft 4, and the axis of the holder shaft 4 is positioned so as to substantially coincide with the upper surface of the turntable 2. The turntable 2 is supported by the base 1 so that the turntable 2 can be tilted left and right about the upper surface thereof. As shown in FIG. 3, a long hole 5a centering on the holder shaft 4 is formed in the back of the holder 5,
The clamp lever 6 is passed through the elongated hole 5a, and a screw portion formed at the tip of the clamp lever 6 is screwed into a screw hole formed on the back surface of the turntable 2. When the clamp lever 6 is loosened, the holder 5 inclines within the range of the elongated hole 5a with the holder shaft 4 as a fulcrum, and when the clamp lever 6 is tightened, the holder 5 becomes the turntable 2 and the clamp lever 6
It is clamped in between and fixed at any position. The long hole 5a is formed in a range in which the holder 5 can be inclined at 45 degrees left and right.

A circular saw portion 8 is supported above the holder 5 via a shaft 7 so as to be vertically swingable with respect to the upper surface of the base 1. A spring 9 for urging the circular saw 8 upward is provided between the holder 5 and the circular saw 8. The circular saw 8 includes a saw shaft 10, a saw blade 11, and a saw cover 1 that covers the upper half of the saw blade 11.
2, a gear case 13, a motor 14 for rotating and driving the saw blade 11, a motor housing 15 for housing and supporting the motor 14, a handle 16, and the like. As shown in FIG. 2, a saw shaft 10 extending in the horizontal direction is provided in the gear case 13, and a saw blade 11 is attached to a tip of the saw shaft 10 via a bolt 17. Although not shown, the motor 14 is
A power transmission mechanism such as a gear for transmitting power from the blade to the saw blade 11 is built in.

Two projections 5b shown in FIG. 2 are mounted on the front surface of the holder 5, and a stopper bolt 1
8 and 19 are screw-fitted in a right angle direction. When the clamp lever 6 is loosened and the holder 5 is inclined, the protrusion 5b engages with the head of the stopper bolt 18 or the stopper bolt 19 at a predetermined inclination angle, and sets the inclined position of the circular saw portion 8. Normally, when the holder 5 is inclined at a position of 45 degrees in the left-right direction, the stopper bolts 18 and 19
Is provided so as to be engaged with.

As is well known, a blade plate (not shown) having a groove into which the saw blade 11 penetrates is fixed on the upper surface of the turntable 2, and the lower end of the saw blade 11 is lower than the upper surface of the turntable 2 during cutting. At this time, the material penetrates into the groove of the blade plate and prevents the material to be cut from fuzzing on the finished surface.

The vise shaft 20 is inserted into an existing vise shaft mounting hole 3a provided on the back of the fence 3,
The vise shaft 20 is fixed to the fence 3 via the knob bolt 23. A hole 22 a provided in the first vise holder 22 and a vise shaft 2
The convex portion 20a of No. 0 is fitted and fixed by the knob bolt 27. The second vice holder 24 is rotatably connected to the first vice holder 22 via a shaft 28.
The shaft 28 is provided with a screw hole 28a, and a knob bolt 29 is screw-fitted. The second vice holder 24 is provided with a screw hole 24a.
A clamp screw 25 that forms a vise attachment body having a tip 6 mounted thereon is screw-fitted. The first vice holder 22 and the second vise holder 24 constitute a first member and a second member of the present invention, respectively. By loosening the knob bolt 29 and rotating the second vice holder 24 about the shaft 28, the second vice holder 24 can be set at an arbitrary position as shown in FIG. 4 or FIG. Therefore, the inclination angle shown in FIG. 4 can be arbitrarily changed in accordance with the mounting angle of the crown member 21, and the crown member 21 can be securely fixed.

A method of cutting the crown member 21 in a slanted manner in the above structure will be described with reference to FIGS. 1, 2 and 4. FIG.

First, the upper end of the crown member 21 is brought into contact with the fence 3 according to the supporting angle. Next, the knob bolt 29 is loosened and the second vice holder 24 is rotated so as to be parallel to the crown member 21, and the knob bolt 29 is tightened to fix the second vice holder 24. The clamp member 25 is advanced to the crown member 21 side, and the crown member 21 is pressed and fixed by the vice plate 26. Thereby, the crown material 21
Is fixed in a stable state. In this state, handle 1
The circular saw portion 8 is pushed down by 6, and the crown material 21 is cut by the saw blade 11.

Next, when the rectangular material 30 is cut, the second vice holder 24 may be fixed in a horizontal state as shown in FIG.

According to the above-described embodiment, the crown member 2 can be easily operated by changing the angle of the second vice holder 24.
1. A vice device capable of securely pressing the rectangular member 30 can be provided, and the vice device of the present invention can be applied without modifying an existing tabletop circular saw.

In the embodiment described above, the vice holder 22 and the vise holder 24 are provided and rotated. However, these are formed as an integral part, and the vice holder 22 and the vice holder 20 are rotated in a fitting portion with the vise shaft 20. May be
In this case, the configuration is further simplified.

[0018]

As described above, according to the present invention, a crown material and a normal rectangular material can be stably supported. Moreover, it can be easily applied to existing tabletop circular saws without modification.
