Abstract

Provided is a router guide that comprises: a guide part that has a first through-hole and a guide surface that guides a cutting tool attachment part of a router device along the first through-hole; a maintaining part that maintains the position of the guide surface; and a positioning part that positions the guide part. The guide surface is formed such that, in a state where the maintaining part is in contact with a surface of a composite material, the distance from the surface becomes smaller as the guide surface approaches a second through-hole. The guide part is formed so as to be elastically deformable. In a case where the guide part is caused to elastically deform along the surface shape of the composite material, the maintaining part maintains the position of the guide surface with respect to the surface at a position that corresponds to the surface shape.

First claim

The invention claimed is:

1. A guide device which guides a router device, which rotates a cutting tool having an outer peripheral surface on which a cutting portion is formed and cuts a workpiece coming into contact with the cutting portion, in accordance with a surface shape of the workpiece having a curvature in at least a predetermined direction, comprising:
a guide portion which includes a first through-hole into which the cutting tool can be inserted, and a guide surface which guides an attachment portion of the router device to which the cutting tool is attached in a state where the cutting tool is inserted into the first through-hole along the first through-hole;
a holding portion which comes into contact with a surface of the workpiece and holds a position of the guide surface with respect to the surface of the workpiece; and
a positioning portion which includes a second through-hole into which a positioning pin positioned in a positioning hole formed in the workpiece is inserted and positions the guide portion at a predetermined position in a radial direction intersecting an axis in which the positioning pin extends in a state where the positioning pin is inserted into the second through-hole,
wherein the guide surface is formed such that a distance from the surface of the workpiece decreases as the guide surface approaches the second through-hole in a state where the holding portion is in contact with the surface of the workpiece,
wherein the guide portion is formed to be elastically deformable, and
wherein in a case where the guide portion is elastically deformed in accordance with the surface shape of the workpiece, the holding portion holds the position of the guide surface with respect to the surface of the workpiece at a position corresponding to the surface shape.

2. The guide device according to claim 1 ,
wherein the guide portion, the holding portion, and the positioning portion are formed as a single member formed of an elastic material.

3. The guide device according to claim 2 ,
wherein a plurality of the guide portions having the first through-hole extending in the radial direction are formed at a plurality of positions around the axis.

4. The guide device according to claim 2 ,
wherein the first through-hole is formed in a spiral shape which extends in a circumferential direction around the axis.

5. The guide device according to claim 2 ,
wherein the holding portion includes a contact portion which is formed to surround the first through-hole and comes into contact with the surface of the workpiece, and a recessed groove portion which communicates with a suction hole connected to a negative pressure source, and
wherein in a case where air in the recessed groove portion is discharged from the suction hole by the negative pressure source in a state where the contact portion is in contact with the surface of the workpiece, the guide portion is elastically deformed in accordance with the surface shape of the workpiece.

6. The guide device according to claim 1 ,
wherein the guide portion is a plate-shaped metal member, and
wherein the holding portion is a plurality of pin members which are formed to protrude from a plurality of locations on one surface of the metal member.
