Abstract

PURPOSE:To readily cut the outer surface of the neck of a wood golf club into uniform thickness relative to a through hole provided therein. CONSTITUTION:A head sole 7 is rotated about the through hole 3 of a neck 2 by rotation of a support 9 to which the head sole 7 is fixed and the outer surface of the neck 2 is cut by a cutting tool into uniform thickness relative to the through hole 3, the cutting tool moving in the direction of the axis of the through hole.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for cutting the surface of the neck of a golf club, particularly a wood club.

0002

[Prior Art] Conventionally, it has been desirable to cut the neck surface of a wood club in a golf club concentrically with the shaft insertion hole because it is necessary to connect the shaft and head in a balanced manner. However, because the head is located asymmetrically with respect to the neck, it is difficult to mechanically cut the neck to maintain a constant wall thickness, and most of the work is done by hand, taking a long time. .

0003

However, when the work is done manually, as mentioned above, the work requires a lot of effort, resulting in an increase in work time and costs. SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned drawbacks of the conventional methods and to precisely and easily cut the neck surface of a wood club using a simple means.

0004

[Means for solving the problem] To this end, the shaft insertion hole of the wood club is the axis center, and the shaft has a fixing point on the sole (bottom surface) of the opposing head, and supports multiple positions of the sole. The club is rotated together with the support rod by the rotating support body, and the outer surface of the neck of the club is cut into a fixed shape symmetrical to the axis by a cutting tool that moves in the axial direction.

[0005]

[Operation] Since the present invention has the above-mentioned configuration, when the sole of the club head is rotated while being supported by a plurality of support rods provided on the support body, the sole is rotated between the fixing point and the shaft insertion rod of the neck. The head rotates around the line that connects the two parts, and even if the head is asymmetrical to the neck, it can rotate smoothly, so the outer surface of the neck is concentric with the insertion hole (same cross-section, same wall thickness). The cutting method is simple and easy to operate.

[0006]

[Example] This will be further explained with reference to an example shown in the drawings. (1) is the head of the wood club; head (1)
A neck (2) protrudes from the upper part of the neck (2), and an insertion hole (2) for connecting the shaft, which is the gripping part of the golf club, is made to protrude from the upper part of the neck (2).
3), (2') indicates the outer surface of the neck (2). (4) is a rotating shaft that is integrated with the support shaft (5) inserted into the insertion hole (3), and is rotatably connected to the drill chuck (6) via a bearing (17).

On the other hand, the bottom surface of the head (1), the sole (7)
is on the axis of the insertion hole (3) and the sole (7
), the sole (7) passes through a sleeve (18) fixed to the support (9), and
The spring (12) attached by the spring stopper (13) presses the head (
1) Rotate. A plurality of support rods (14) are provided on the support (9) so that their lengths can be adjusted, and these support rods (14) (14)... - is abutted on the round surface (7) and rotates about the fixed shaft (10) along with the rotation of the support body (9) without changing their positional relationship. (8) is a rotating part to which the support (9) is attached; (11)
) is a support portion of the fixed shaft (10).

Separately from the golf club support portion described above, a cutting tool stand (16) is provided which can move in the axial direction of the insertion hole (3), and a cutting tool (15) is mounted on this cutting tool stand (16). The cutting tool (15) is mounted and fixed so that it can move forward and backward at right angles to the axial direction of the insertion direction (3) according to the predetermined shape of the neck (2) in the head (1).

Since the embodiment of this device has the above-mentioned configuration, a support shaft (5) supporting the neck (2) and a sole (7) are provided between the drill chuck (6) and the rotating part (8). The head (1) is centered around a fixed shaft (10) that supports the head (1), and a plurality of support rods (14) provided on the support body (9) support the head (1).
The outer surface (2') of the neck (2) supports the sole (7) of the neck (2) and rotates as the sole (7) of the neck (2) rotates.
Since the cutting tool (15) can be smoothly rotated around the neck (2), the cutting tool (15) is brought into contact with the outer surface of the neck (2), and the cutter (15) is pressed against the outer surface of the neck (2) to form the intended outer shape (for example, the wall thickness increases as it approaches the head body). By moving the cutting tool (15) forward and backward according to the shape of the long conical head, a neck with a uniform thickness in cross section can be obtained, and its accuracy can be easily improved. In addition, the sole should be properly plated after cutting.
Since the recess is formed at the contact portion of the support rod, it is not exposed as it is.

As described above. According to this invention, even a head having an asymmetrical shape with respect to the neck can be rotated around the insertion hole provided in the neck, making it easy to cut the outer surface of the neck and concentrically around the insertion hole. It has the excellent effect of ensuring precision with a simpler operation compared to conventional methods.
