Abstract
A tool head is provided that can easily correct the shape of a tooth surface. Slot holes are formed in a main head body, that tilt either distally or proximately to the central axis of rotation (CAR) of the main head body. Concave tooth surface blades for cutting concave tooth surfaces are installed in the slot holes that tilt distally, and convex tooth surface blades for cutting convex tooth surfaces are formed in the slot holes that tilt proximately. By changing the amount that the concave or convex tooth surface blades protrude, the cutting portions of the concave or convex tooth surface blades are moved in either distal or proximate directions. By changing the distance from the CAR to the cutting portions in this manner, it is possible to correct the shape of the concave or convex tooth surfaces of a bevel gear.
Claims15
A tool head for cutting bevel gears, comprising:
- a disk shaped main head body in which a plurality of installation holes that are tilted in a distal or proximate direction from a central axis of rotation (CAR) of said main head body are formed along a circumferential direction of the main head body;
- blades that are installed in said installation holes such that they can freely move outwardly and inwardly through said installation holes, having cutting portions on the tip end thereof that protrude from one end surface of said main head body;
- and
- fastening mechanisms that are provided on said main head body and fasten said blades to said main head body such that said blades protrude a discretionary amount;
- wherein
- by changing the amount that said blades protrude, the distance from said CAR of said main head body to said cutting portions is changed.
A tool head for cutting bevel gears, comprising:
- a disk shaped main head body in which installation holes having a first reference surface and second reference surface in one corner thereof are formed in a thickness direction of said main head body;
- blades having a base section that is inserted in the installation holes of said main head body, and cutting portions that are continuous with said base sections and that protrude from one end surface of said main head body;
- and
- fastening mechanisms that are installed in said main head body and fasten said blades by pressing the base sections of said blades against said first reference surfaces and said second reference surfaces;
- wherein
- said first reference surfaces and said second reference surfaces are formed in a direction such that they receive a cutting load acting on said blades.
A tool head for cutting bevel gears, comprising:
- a disk shaped main head body in which installation holes each having a first reference surface and a second reference surface are formed in a thickness direction thereof;
- blades having base sections that are inserted into the installation holes of said main head body, and cutting portions that are continuous with the base sections and that protrude from one end surface of said main head body;
- and
- fastening mechanisms that are provided in the installation holes of said main head body, and that fasten said blades by pressing the base section of said blades against the first reference surfaces and the second reference surfaces of said installation holes;
- wherein
- said blades are located distally from a CAR of said main head body than said fastening mechanisms, and
- said fastening mechanisms are located proximately to the CAR of said main head body than said blades.
