Abstract
A golf club testing machine includes a swing arm mechanism, an upper section supporting the swing arm mechanism, a barrel section supporting the upper section in a manner such that the upper section is adjustable at a forwardly inclined angle, a base section supporting the barrel section in a manner such that the barrel section is rotatable in a horizontal plane at a constant height, and a hit assisting mechanism rotating the barrel section in a horizontal plane in unison with the swing arm mechanism.
Claims10
A golf club testing machine, including a first arm rotated by a servomotor, the first arm comprising:
- a swing arm mechanism including a second arm having a holder structure of a golf club, the second arm being rotated in unison with the first arm by a motor different from the servomotor,
- an upper section supporting the swing arm mechanism,
- a barrel section supporting the upper section in a manner such that the upper section is adjustable at a forwardly inclined angle,
- a base section supporting the barrel section in a manner such that the barrel section is rotatable in a horizontal plane at a constant height relative to the base section, and
- a hit assisting mechanism rotating the barrel section in a horizontal plane in unison with the swing arm mechanism.

- a base section supporting the barrel section in a manner such that the barrel section is rotatable in a horizontal plane at a constant height,
- a hit assisting mechanism rotating the barrel section in a horizontal plane in unison with the swing arm mechanism,
- a cylindrical body arranged on the second arm of the swing arm mechanism and having at the center thereof an insertion hole receiving a grip of a golf club,
- first and second chuck different in structure from each other and arranged at two locations respectively along the longitudinal direction of the cylindrical body,
- an external screw arranged on an outer circumference of the cylindrical body on an entry side of the grip insertion hole, and
- a tapered hole arranged on an inner circumference of the cylindrical body on the entry side of the grip insertion hole and tapered to a rear end of the grip insertion hole,
- wherein the first chuck includes a plurality of split collet members, each collet member having a tapered outer curved surface at the same inclination as the inclination of the tapered hole and having an inner arc curved surface tightly in contact with the external surface of the grip, and
- a cap nut screwed around the external screw and causing the collet members into the tapered hole.
