Description

TECHNICAL FIELD The present invention relates to a saw cutting jig that can cut a material to be cut with high accuracy at a desired cutting surface.

Skilled technology is required to cut a material such as wood with a saw at the intended cutting surface.If a person who is not an expert cuts it, the blade will shake when pushing and pulling the saw. , A highly accurate cut surface cannot be obtained.

In Patent Documents 1 and 2, in order to prevent such blurring of the saw blade, a saw is attached to the side surface (blade surface) of a saw using a magnet on a guide plate having a surface substantially parallel to the cutting surface. A cutting jig is described (see Patent Documents 1 and 2).

JP, 2004-114666, A JP, 2007-83698, A

However, in the jigs for saw cutting described in Patent Documents 1 and 2, since the material to be cut such as wood and resin material is fixed manually, the material to be cut shifts while cutting with a saw, It becomes difficult to form a highly accurate cut surface.
Further, in the saw cutting jigs described in Patent Documents 1 and 2, depending on the size of the material to be cut and the like, while cutting and advancing, a portion of the saw blade surface that is not attracted to the guide plate by the magnet Many of them occur and the movement of the blade surface of the saw shakes. As a result, it becomes difficult to form a highly accurate cut surface.

Therefore, it is an object of the present invention to provide a saw cutting jig capable of cutting a material to be cut with high accuracy at a desired cutting surface.

The present invention, a first fixing member having a first guide surface for moving the blade of the saw along the cutting surface of the material to be cut,
A second fixing member having a second guide surface for moving the blade of the saw along the cutting surface,
A first magnet that is embedded in the first fixing member and that attracts the saw blade surface to the first guide surface;
A second magnet embedded in the second fixing member, which attracts the blade surface of the saw to the second guide surface,
A saw cutting jig, wherein the material to be cut is sandwiched by the first fixing member and the second fixing member.

ADVANTAGE OF THE INVENTION According to this invention, the jig for saw cutting which can cut|disconnect a to-be-cut material highly accurately in a desired cut surface can be provided.

It is a perspective view showing the state where the screw type clamp of the jig for saw cutting concerning a first embodiment was loosened. It is a perspective view showing the state where the screw type clamp of the jig for saw cutting concerning a first embodiment was tightened. It is a perspective view from the guide surface side of the jig for saw cutting concerning a second embodiment. It is a perspective view from the opposite side to the guide surface of the jig for saw cutting concerning a second embodiment. It is a figure which shows the use condition of the jig for saw cutting which concerns on 1st embodiment. It is a figure which shows the use condition of the jig for saw cutting which concerns on 2nd embodiment.

The saw cutting jig according to the present invention will be described in detail.
A saw cutting jig according to the present invention includes a first fixing member having a first guide surface for moving a saw blade along a cutting surface of a material to be cut, and a saw blade moving along the cutting surface. A second fixing member having a second guide surface, a first magnet embedded in the first fixing member, which attracts the saw blade surface to the first guide surface, and a second fixing member embedded in the second fixing member. A second magnet that attracts the saw blade surface to the second guide surface, and the material to be cut is sandwiched by the first fixing member and the second fixing member.

By having such characteristics, it is possible to prevent the blade surface of the saw from shaking when the material to be cut such as wood or resin material is being cut by the saw. Especially when cutting a material with a large amount of cutting, the magnet is arranged on the fixed member even if the cutting is carried out, so that the saw blade is attracted to each guide surface by the magnet. It does not come off. As a result, the material to be cut can be cut with high accuracy at a desired cut surface. Further, since the saw blade is attracted to each guide surface, the material to be cut can be cut with a small force. Further, since the blade surface of the saw can be prevented from shaking, the sawing operation can be safely performed. Further, the sawing operation can be performed without relying on the visual sense.

<First embodiment>
Hereinafter, a first embodiment of the saw cutting jig of the present invention will be described.

The width of the third guide surface 43 is preferably 10 mm or more and 40 mm or less, and more preferably 15 mm or more and 30 mm or less. If the width is too small, it may be difficult to sufficiently attract the blade surface of the saw depending on the strength of the third magnet 34 described later. Further, if the width is too large, the cutting distance of the saw blade becomes short depending on the length of the saw blade, which makes the sawing operation difficult.
Further, the support member 4 has a third magnet 34 inside which the third guide surface 43 attracts the saw blade surface.
