Method and apparatus for measuring face angle
A method ( 250 ) and apparatus ( 20 ) for measuring the face angle of a golf club ( 300 ), golf club head ( 302 ) or face component ( 304 ) of a golf club head is disclosed herein. The method ( 250 ) and apparatus ( 20 ) use a non-contact displacement measuring assembly ( 24 ) to determine the face angle. The method ( 250 ) and apparatus ( 20 ) is utilized with right-handed and left handed golf clubs ( 300 ), golf club heads ( 302 ) and face components ( 304 ). The apparatus ( 20 ) generally includes a base assembly ( 22 ), a non-contact displacement measuring assembly ( 24 ), a shaft center sensor assembly ( 26 ), a base plate assembly ( 28 ), a lie adjustment assembly ( 30 ) and a shaft support assembly ( 32 ).
1. A method for measuring the face angle of a golf club, a golf club head or a face component, the method comprising:
orienting the golf club, the golf club head or the face component on a base plate of an apparatus;
aligning a face center locating device with a center point of a face of the golf club, golf club head or the face component; and
determining the face angle of the golf club, golf club head or face component by measuring the distance of a plurality of non-contact displacement measuring devices, at least two of the plurality of non-contact displacement measuring devices positioned on opposite sides of the face center locating device.
2. The method according to claim 1 wherein the face center locating device and the plurality of non-contact displacement measuring devices are lasers.
3. A method for measuring the face angle of a golf club, the method comprising:
placing a golf club head of the golf club on a base plate of an apparatus;
placing a shaft of the golf club in a shaft support assembly;
aligning the shaft with a lie angle of a golf club on a lie scale plate of the apparatus;
centering the shaft of the golf club within a shaft center sensor assembly of the apparatus;
aligning a face center locating device with a center point of a face of the golf club; and
determining the face angle of the golf club by measuring the distance of a plurality of non-contact displacement measuring devices, at least two of the plurality of non-contact displacement measuring devices positioned on opposite sides of the face center locating device.
4. The method according to claim 3 wherein the face center locating device and the plurality of non-contact displacement measuring devices are lasers.
5. The method according to claim 3 wherein the golf club head of the golf club is placed on a tacky surface of the base plate.
6. The method according to claim 3 wherein centering the shaft within the shaft center sensor assembly comprises moving the base plate forward, rearward and laterally.
7. The method according to claim 3 wherein aligning the face center locating device comprises moving a non-contact displacement measuring assembly vertically and horizontally relative to the base plate.
8. A method for measuring the face angle of a golf club head, the method comprising:
attaching a mandrel to golf club head, the mandrel simulating a shaft for the golf club head;
placing the golf club head on a smooth surface of a base plate of an apparatus;
placing the mandrel attached to the golf club in a shaft support assembly;
aligning the mandrel with a lie angle for the golf club head on a lie scale plate of the apparatus;
centering the mandrel attached to the golf club head within a shaft center sensor assembly of the apparatus;
aligning a face center locating device with a center point of a face of the golf club head; and
determining the face angle of the golf club head by measuring the distance of a plurality of non-contact displacement measuring devices, at least two of the plurality of non-contact displacement measuring devices positioned on opposite sides of the face center locating device.
9. A method for measuring the face angle of a face component of a golf club head, the method comprising:
attaching a mandrel to face component, the mandrel simulating a shaft for the golf club head;
placing the face component on a smooth surface of a base plate of an apparatus;
placing the mandrel attached to the face component in a shaft support assembly;
aligning the mandrel with a lie angle for the golf club head on a lie scale plate of the apparatus;
centering the mandrel attached to the face component within a shaft center censor assembly of the apparatus;
aligning a face center locating device with a center point of a face of the golf club head; and
determining the face angle of the face component by measuring the distance of a plurality of non-contact displacement measuring devices, at least two of the plurality of non-contact displacement measuring devices positioned on opposite sides of the face center locating device.
