1. Field of the invention
The present disclosure relates to a fixture for welding a golf club head, particularly a fixture for welding fabrication of a golf club head which reduces costs of mold making, simplifies the manufacturing process, and is economical of expenditures of manufacturing golf club heads.
2. Description of the prior art
A golfer has to use golf clubs with distinct materials and structures for tee-off or putt, particularly tee-off which requires a golf club head hitting golf balls with strong power. Accordingly, specific sheet metal should be welded on the hitting surface of a golf club head in a special welding process.
Considering conditions of conventional fixtures for manufacture of golf club heads such as high manufacturing cost and low speed of clamping a golf club head, the patent applicant developed a fixture for welding fabrication of a golf club head after years of research.
The present disclosure is to provide a fixture for welding fabrication of a golf club head which depends on a single fixture to position and weld different types of golf club heads with specific sizes.
To this end, a fixture for welding fabrication of a golf club head comprises a first fixing support, a second fixing support, a first moveable support and a second moveable support, all of which are installed on a platform: the first fixing support and the second fixing support are perpendicular to each other; the first moveable support and the first fixing support are parallel to each other; the second moveable support and the second fixing support are parallel to each other; the first fixing support comprises a first clamping part; the second fixing support comprises a second clamping part; the first moveable support comprises a first stroke unit and a third clamping part; the second moveable support comprises a second stroke unit and a fourth clamping part.
On a golf club head, a hitting surface to be welded should face up and is placed on the platform so that the peripheral surface of the golf club head contacts the first clamping part and the second clamping part. Next, the first stroke unit and the second stroke unit are used in driving the third clamping part to move toward the first clamping part and driving the fourth clamping part to move toward the second clamping part, respectively. As such, the golf club head is held among the first clamping part, the second clamping part, the third clamping part and the fourth clamping part and free from movement toward another side, which is opposite to the hitting surface being welded, by means of a fifth clamping part so that the hitting surface is welded on the golf club head.
Referring to
The second fixing support 3 and the first fixing support 2 are adjacent to each other; the first moveable support 4 and the first fixing support 2 are opposite to each other; the second moveable support 5 and the second fixing support 3 are opposite to each other; the first clamping part 22 is arranged on a plane of the first fixing support 2 opposite to the first moveable support 4; the third clamping part 42 is arranged on a plane of the first moveable support 4 opposite to the first fixing support 2 and corresponds to the first clamping part 22; the second clamping part 31 is arranged on a plane of the second fixing support 3 opposite to the second moveable support 5; the fourth clamping part 52 is arranged on a plane of the second moveable support 5 opposite to the second fixing support 3 and corresponds to the second clamping part 31; the first stroke unit 41 is used in driving the third clamping part 42 to move toward the first fixing support 2; the first stroke unit 41 and the third clamping part 42 are provided with a resilient cushion unit (not shown in figures) in between; the second stroke unit 51 is used in driving the fourth clamping part 52 to move toward the second fixing support 3; the first clamping part 22 and the third clamping part 42 comprises a V-shaped groove 221 and a V-shaped groove 421, respectively.
Moreover, the first moveable support 4 is provided with a first displacement structure 43 by which the first moveable support 4 is adjusted in distance between the first moveable support 4 and the first fixing support 2; the second moveable support 5 is provided with a second displacement structure 53 by which the second moveable support 5 is adjusted in distance between the second moveable support 5 and the second fixing support 2.
Referring to
Next, the first stroke unit 41 should drive the third clamping part 42 to move toward the first fixing support 2, allowing both opposite ends on the golf club head 6 to be held by the V-shaped groove 221 on the first clamping part 22 and the V-shaped groove 421 on the third clamping part 42; the second stroke unit 51 should drive the fourth clamping part 52 to move toward the second fixing support 3, allowing the periphery of the golf club head 6 to be securely held by the first clamping part 22, the second clamping part 31, the third clamping part 42 and the fourth clamping part 52. Moreover, the golf club head 6 simultaneously held by the first clamping part 22, the second clamping part 31, the third clamping part 42 and the fourth clamping part 52 is grasped, positioned, and not shaken along the periphery in four directions perpendicular to one another because the first fixing support 2 and the first moveable support 4 in a fixture for welding fabrication of a golf club head are perpendicular to the second fixing support 3 and the second moveable support 5, respectively. As such, a robot for automated welding of the golf club head 6 can be positioned in place. Because the reverse side opposite to the welded hitting surface on the golf club head 6 is inserted into the V-shaped groove 111 on the fifth clamping part 11, the golf club head is free from movement toward the reverse side which is opposite to the welded hitting surface, securely held in a fixture for welding fabrication of a golf club head, and easily operated without repositioning and adjusting the position of the golf club head by a welding machine operator.
Additionally, each of the V-shaped groove 111 on the fifth clamping part 11, the V-shaped groove 221 on the first clamping part 22 and the V-shaped groove 421 on the third clamping part 42 in a fixture for welding fabrication of a golf club head is designed as a component with the groove tapered outside-in which facilitates a golf club head 6 with a distinct size to be securely grasped and welded in a fixture for welding fabrication of a golf club head. When the golf club head 6 is held in a fixture for welding fabrication of a golf club head, residual clamping force is absorbed by a resilient cushion unit between the first stroke unit 41 and the third clamping part 42 because of the first stroke unit 41 driving the third clamping part 42 to move toward the first fixing support 2 and grasp the golf club head 6 in the V-shaped groove 221 of the first clamping part 22 as well as in the V-shaped groove 421 of the third clamping part 42; moreover, residual clamping force is also absorbed by the resilient cushions 33 between the second clamping part 31 and the second fixing support 3 when the second stroke unit 51 drives the fourth clamping part 52 to move toward the second fixing support 4 and grasp the golf club head 6 between the second clamping part 31 and the fourth clamping part 52. As such, the golf club head 6 is free from surface abrasion. A surface of the golf club head 6, which relies on adjustable lengths of the fastening parts 522 forming a triangular arrangement on the fourth clamping part 52, will contact the corresponding fourth clamping part 52; a reverse surface of the golf club head 6, which relies on the resilient cushions 33 on the second clamping parts 31 adapted to a cambered surface, will contact the three corresponding second clamping parts 31 by means of the three resilient cushions 33 for good stability.
In a fixture for welding fabrication of a golf club head, the third clamping part 42 (the fourth clamping part 52) driven by the first stroke unit 41 (the second stroke unit 51) has a limited stroke. Accordingly, a fixture for welding fabrication of a golf club head can be further applied to various golf club heads distinct from one another in size because a distance between the first moveable support 4 and the first fixing support 2 and a distance between the second moveable support 5 and the second fixing support 3 are adjusted by the first displacement structure 43 and the second displacement structure 532, respectively.
It can be seen from above descriptions that a technically innovative fixture for welding fabrication of a golf club head with effects and advantages over conventional fixtures for welding golf clubs meets patentability including novelty and non-obviousness.
Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
