Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an attachment for supporting a material to be cut when cutting a wide material or a long material using a tabletop circular saw.

[Background of the idea]

The prior art will be explained with reference to FIGS. 6 and 7.

The cutting range of the material to be cut by the saw blade 8 is the exposed portion of the saw blade 8 exposed from the lower end of the saw cover 7. Therefore, normally, the workpiece is supported by the upper surface of the base 1 and the workpiece support surface 9a of the fixed fence 9, and the lowering range of the saw blade 8 is limited, so the cutting width and height of the workpiece are limited. There were limits to this.

However, in order to cut a workpiece that is wider or taller than usual within the cuttable range of the saw blade 8, the following method has conventionally been used.

A wide material to be cut as shown in Figure 6 (hereinafter referred to as
When cutting a wide material 12), use a backing plate 13 so that the wide material 12 is located at a position where no uncut parts are left after cutting, place the wide material 12 on the top surface of the backing plate 13, and cut. was.

However, there is also the inconvenience that when the main body is brought to a work site, the backing plate 13 must also be brought in.

In addition, when cutting a tall material to be cut as shown in FIG. 7 (hereinafter referred to as the vertical material 15),
The vertically long material 15 was supported on the side surface of the backing plate 13 for cutting.

However, when performing angle cutting by rotating the rotary table 2 during vertical cutting, the dimension from the fixed fence 9 to the contact point between the outer periphery of the saw blade 8 and the top surface of the rotary table 2 changes, so the width of the backing plate 13 changes. Several types were needed.

[Purpose of invention]

The present invention eliminates the above-mentioned conventional drawbacks and simplifies the cutting work by making it possible to cut wide or long materials without using a backing plate.

[Structure of the idea]

In the present invention, a movable fence consisting of bars parallel to the upper surface of the base and a plate having a plane perpendicular to the upper surface of the base is movably attached to a bolt erected at the rear of the fixed fence, and by tightening the bolt, the movable fence is The position of the fence is fixed, and the material to be cut can be supported on the top and side surfaces of the movable fence.

[Example of idea]

An embodiment of the present invention will be described using FIGS. 1 to 5. FIG. 1 is a side view of a table-top circular saw showing an embodiment of the present invention, and FIG. 2 is a top view of FIG. 1.

In the figure, a recess is formed in the center of the base 1, and the rotary table 2 is rotatable in the horizontal direction in the recess.
Further, the rotary table 2 is buried so that the upper surface thereof is flush with the upper surface of the base 1. rotary table 2
A holder 3 is provided at the bottom, and the rear of the holder 3 stands upright. A fixed handle 4 for fixing rotation of the rotary table 2 is screwed into the front end of the holder 3. A circular saw portion 14 is pivotally supported at the upper end of the holder 3 so as to be slidable vertically toward the upper surface of the base 1 via a shaft 5. The circular saw part 14 includes a saw blade 8, a saw cover 7 that covers the upper half of the saw blade 8, and a cutting handle 6 that pushes down the circular saw part 14. A fixed fence 9 for supporting the material to be cut is provided on the upper surface of the base 1, and a movable fence 10 is attached to bolts 11 erected at the rear of the fixed fence 9.

FIG. 3 is a sectional view taken along the line -- in FIG. 2. Third
In the figure, the movable fence 10 consists of bars 10a arranged parallel to the upper surface of the base 1, and a plate 10b provided at the tip of the bar 10a and having a plane perpendicular to the upper surface of the base 1, with a long hole 10c in the axial direction of the bar 10a. It is formed. The movable fence 10 moves in the front-back direction by loosely fitting the bolt 11 into the elongated hole 10c. The movable fence 10 is fixed in position by tightening bolts 11.

In the above configuration, when cutting the wide material 12 shown in FIG. , perform cutting work with the saw blade 8.

When cutting the vertically long material 15 shown in FIG.
is moved and fixed, and the vertically elongated material 15 is abutted against the side surface of the plate 10b to perform the cutting operation.

[Effect of idea]

According to the present invention, since a movable fence that can be moved back and forth is provided in addition to the fixed fence, the cutting position of the material to be cut can be variably set, eliminating the need for several types of backing plates to match the cutting conditions as in the past. , it is possible to cut wide and vertical materials using only the main body.

Furthermore, the inconvenience of having to bring in a patch plate when bringing the main body to the site can be eliminated.
