Abstract

(57) [Summary] [Purpose] To make it possible to perform rough cutting work prior to engraving efficiently and safely using a widely used electric saw. [Structure] A jig for cutting is configured to be attached to the surface side of the base of an electric saw, and this jig forms a groove that exposes part of the saw blade to the outer peripheral surface, and the center of this groove is the base. It is formed as a curved surface that is higher in the front-back and left-right directions.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 When engraving on a large piece of wood, use an electric saw that is commonly used for roughing work prior to engraving, and use a cutting jig that can be easily attached to and detached from the electric saw for efficient and safe roughing. Providing to facilitate roughing work by carvers and carpenters.

[Prior art]

 Electric saws are often used in homes and carpenters for cutting wood or carving grooves. As a blade used for an electric saw, a circular saw blade for cutting or a groove cutting blade for cutting a groove is used. On the other hand, when engraving on large wood, a hatchet or large chisel (only) is used, but the cutting efficiency is not good. On the other hand, as the blade of the electric saw, a circular saw blade or a grooving blade is used as described above, but the electric saw is moved only in the rotational centrifugal direction of the saw blade or the cutting material is moved to perform cutting. is there.

By the way, when cutting wood using a rough circular saw blade, since the cutting blade portion formed on the side edge of the blade can efficiently cut the wood, hold the electric saw in your hand and cut the blade shallowly. By moving the electric saw against the rotating centrifugal direction of, we are able to experience good cutting. However, this method has an electric saw in the middle, is not stable and is extremely dangerous, and is the most cutting tool to be excluded.

[0004]

[Problems to be solved by the device]

 Therefore, the present invention uses an electric saw with good cutting efficiency and a relatively rough circular saw blade to perform rough cutting prior to large-scale engraving.It is configured integrally with the electric saw and supports the saw section. The structure is such that a special jig is attached to the surface (working surface) of the existing base to dramatically improve the rough cutting work.

[0005]

[Means for Solving the Problems]

 This cutting jig is configured to be attached to the surface side of the base that supports the electric saw, and forms a groove that exposes part of the saw blade, and the central part of this groove is sequentially from the front and back and left and right directions of the base. It is a highly curved surface.

【Example】

 The present invention will be described in detail below with reference to the drawings. The drawings show an example of a specific embodiment of the present invention applied to an electric saw shown as an example, and the present invention is not limited to the illustrated examples. Alternatively, within the scope of the description described below, the same operation can be performed even if a part of the design is changed or a part of the configuration is changed. FIG. 1 (partially cutaway side view), FIG. 2 (right side partially cutaway front view of FIG. 1) and FIG. 3 (bottom view of FIG. 2) show an example of an electric saw 1 using the cutting jig of the present invention. A commonly used electric saw is a sturdy card with a pivot seat 3 provided on the front side of the base 2 (right side in the drawing) and a support rod 3a pivotally supported on the rear side of the base. 4 is fixed. The guard 4 and the body portion 4a are integrally or combined and connected, and these are fixed by attaching the grip portion 5 and the motor portion 5a to an integrally formed combined body.

A drive shaft for attaching a saw blade is arranged at the center of the card 4, and a saw blade 6 is attached to the drive shaft. The angle of the saw blade 6 with respect to the lower surface of the base 2 is adjusted and fixed by the tightening screw 3c, and the length of the saw blade 6 protruding from the base 2 is adjusted by the tightening screw 3b. The present invention uses such an electric saw to perform rough cutting prior to large-sized wood carving. This rough cutting allows the electric saw to move in any direction and tilt freely while protruding from the base 2. The cutting is performed by using the front edge of the blade 6.

In order to perform such cutting, the number of saw blades protruding from the base 2 is made small and the electric saw can be moved and cut laterally (in the paper surface penetrating direction in FIG. 1, left and right direction in FIG. 2), Since the lower surface of the base 2 is a flat surface, only the surface can be cut. Therefore, in the present invention, as shown in the figure, a jig 7 is attached to the surface side of the base 2 supporting the electric saw 1 to enable rough cutting.

As shown in FIG. 4 (conceptual drawing), the jig 7 has a mounting surface that substantially coincides with the surface of the base 2, and mounting portions 7b and 7c are formed before and after the mounting surface. Each of them is formed with a screw hole to be attached to the base 2. Then, the groove 7a is formed so as to correspond to the saw blade 6. Further, the jig 7 is a circular curved surface having a tip portion at which the saw blade 6 projects as shown in the figure, and the circular curved surface is a curved surface as shown in FIGS. 1 and 2. In the figure, this curved surface is shown with different curvatures on the left and right sides of the saw blade 6, but this is because the saw blade 6 is away from the center of the base 2, and the base 2 may be changed or If the jig 7 is configured so that the mounting surface of the jig 7 is not aligned with the lower surface of the base 2, the left and right circular curved surfaces can be the same. You may comprise so that the groove 7a which projects a blade may be formed. Reference numeral 8 shown in FIGS. 1 and 2 denotes a door cover which is provided if necessary, and is provided on the card 4 via a hinge 8a to prevent scattering of cutting pieces.

On the other hand, as the jig 7, as shown in FIG. 4, a light metal casting product is recommended, and it is recommended that it is hollow and lightweight, but it may be formed in a solid shape to form the groove 7 deeply. May be molded from hard wood or a hard synthetic resin material having abrasion resistance. When mounting to the base 2, the mounting parts 7b and 7c are not formed as shown in the figure, but a concave portion and a screw hole formed subsequently to the curved surface are provided in a part of the curved surface and the base 2 is mounted. You may.

[Effect of device]

 In the present invention, since such a jig 7 is attached to the electric saw, the amount of protrusion of the saw blade 6 is adjusted to determine the rough cutting size, and the electric saw 1 is set in the free direction and at a free angle in FIG. By being able to move, roughing work prior to engraving can be performed extremely efficiently. In addition, since the electric saw can be cut while being pressed against the engraving material, there is little danger and it can be used even by an amateur.
