Description

Technical Field

[0001] This utility model belongs to the field of golf club manufacturing technology, and in particular relates to a fixing clamp for golf club manufacturing. Background Technology

[0002] In golf club manufacturing, which includes the club and the clubhead attached to the club end, the welding process requires the clubhead to be stably fixed to a fixture. Current technology commonly uses a three-point positioning fixture based on the clubhead's outer contour. However, this method has inherent drawbacks: due to manufacturing tolerances in the pre-machined welding positions of the clubhead, and the rigidity of the contour positioning structure, it cannot adaptively compensate for hole position deviations. This directly leads to the weld point deviating from the preset position during welding, resulting in defective products. This not only reduces the product yield but also slows down the production line due to rework adjustments, severely impacting production efficiency and quality consistency. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of this utility model is to provide a fixing fixture for golf club production, so as to solve the technical problem that the existing rigid positioning fixtures for the outer contour of the club head in the production process cannot compensate for the manufacturing tolerance of the welding holes, resulting in weld point misalignment and increased defect rate.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution provided in this application is as follows:

[0007] A fixing fixture for golf club manufacturing includes: a mounting base with a fixing groove on its top surface; a bar magnet embedded in the fixing groove with its first end exposed, the bar magnet being used to attract a golf club head placed on the mounting base with a round hole; and a positioning pin vertically passing through the first end of the bar magnet and inserted into the round hole of the golf club head.

[0008] When fixing the ball head, the initial axial positioning is achieved by pre-aligning the positioning pin with the ball head's circular hole. Then, the ball head is attached to the mounting base and fixed by magnets. Afterward, the operator or robot can flexibly adjust the horizontal position of the ball head under the continuous action of magnetic force, directly compensating for the welding hole position deviation caused by the production process, ensuring that the welding hole is accurately aligned with the equipment welding point, reducing the welding defect rate caused by positioning errors. At the same time, this open structure eliminates the dependence of traditional contour positioning on the ball head's shape, allowing ball heads of different brands and models to be stably clamped, significantly improving versatility. In addition, the magnetic fixing method eliminates the mechanical clamping step, improving the efficiency of ball head loading and unloading.

[0009] In some embodiments, the mounting base is L-shaped and includes a horizontal portion and a vertical portion. A fixing groove is formed on the horizontal portion, and a clearance space is formed between the horizontal portion and the vertical portion for the ball head to be placed and adsorbed.

[0010] The L-shaped mounting bracket provides a stable placement area for the ball head by providing clearance space. The vertical part naturally restricts the lateral displacement of the ball head, while the horizontal part ensures that the magnetic surface is flat, thereby improving positioning reliability and simplifying the clamping process.

[0011] In some embodiments, a magnetic flux hole penetrating the horizontal portion is provided at the bottom of the fixing groove.

[0012] The magnetic flux hole weakens the shielding effect of the mounting base on the magnetic field, allowing the magnetic force of the bar magnet to be transmitted to the ball head more efficiently, ensuring adsorption stability, and is especially suitable for ball heads with uneven surfaces or heavy weight.

[0013] In some embodiments, it further includes: a first locking knob, which is threadedly connected to the mounting base and has one end extending into the fixing groove to abut against the bar magnet.

[0014] The first locking knob can quickly lock or replace the bar magnet, preventing positioning failure caused by magnet loosening after long-term use, extending the fixture's lifespan and reducing maintenance costs.

[0015] In some embodiments, it further includes: a second locking knob, which is threadedly connected to the bar magnet and corresponding to the positioning pin, one end of which extends into the bar magnet and abuts against the positioning pin.

[0016] In addition to locking the positioning pin, the second locking knob also allows for individual adjustment of the positioning pin's extension height, flexibly adapting to ball-head holes of different depths and further expanding the clamp's compatibility.

[0017] In some embodiments, there are two fixing slots arranged in parallel, each fixing slot is provided with a strip magnet, and there are two positioning pins, each positioning pin passing through the first end of the strip magnet.

[0018] The dual magnet and dual positioning pin structure not only improves the adsorption stability of large ball heads, but also automatically corrects the horizontal angle deviation of the ball head through two-point positioning, avoiding the deflection problem caused by single-point force. At the same time, it can also adsorb the ball head onto the mounting base in any left or right direction, making operation convenient.

[0019] In some embodiments, the upper end of the vertical portion of the mounting base is higher than the horizontal portion to form a limiting step, and the limiting step abuts against the second end of the bar magnet placed in the fixing groove.

[0020] The limiting step prevents the bar magnet from sliding in the mounting groove, thus preventing magnet misalignment caused by frequent assembly and disassembly, and ensuring long-term alignment between the positioning pin and the ball head hole.

[0021] In some embodiments, a locking hole is provided through the vertical portion of the mounting base.

[0022] The locking hole supports the bolts to be fixed to the production line table, solving the problem of fixture displacement caused by welding vibration, and at the same time facilitating quick disassembly and assembly and layout adjustment of the production line. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0033] This utility model provides a fixing fixture for golf club production, mainly including a mounting base 1, a bar magnet 2, and a positioning pin 3. The mounting base 1 is made of metal (preferably aluminum alloy to reduce weight), and its top surface is machined with a rectangular fixing groove 11, approximately 15mm deep. The bar magnet 2 is embedded in the fixing groove 11, with its top extending out of the groove 11; the magnet uses neodymium iron boron permanent magnet material, with a magnetic field strength of not less than 3000 Gauss. The lower end of the positioning pin 3 has a conical structure, vertically penetrating the first end of the bar magnet 2, and is inserted into the pre-machined circular hole 601 in the ball head 6 for initial positioning. During operation, first align the circular hole 601 of the ball head 6 with the positioning pin 3, then move the ball head 6 towards the bar magnet 2 until it is attracted and fixed. At this time, the lower end of the positioning pin 3 is inserted into the circular hole 601. The horizontal position of the ball head 6 can be adjusted by rotating (fine-tuning) the positioning pin 3 around its axis to compensate for hole position tolerances.

[0034] Specifically, the pre-machined circular hole 601 of the ball head 6 is formed in other processes and serves as the positioning reference for the fixed fixture.

[0035] Setting the lower end of the positioning pin 3 into a tapered structure facilitates its quick and accurate insertion into the round hole 601.

[0036] Furthermore, the mounting base 1 is designed as an L-shaped integral cast structure, comprising a horizontal part 12 and a vertical part 13. The horizontal part 12 is approximately 50 mm wide, and the fixing groove 11 is formed on its surface; the vertical part 13 is approximately 60 mm high, and is vertically welded to the horizontal part 12 or integrally formed. A 90° clearance space 14 is formed at the connection between the two.

[0037] Specifically, a circular magnetic flux hole 111 with a diameter of approximately 8 mm is opened at the bottom of the fixing groove 11, which penetrates the bottom surface of the horizontal part 12. By reducing the metal shielding area, the magnetic lines of force are more concentrated and penetrate to the ball head 6. Tests have shown that this design increases the adsorption force by approximately 40%, and is particularly suitable for titanium alloy ball heads 6 weighing over 200g.

[0038] Based on this, a first locking knob 4 is added. This knob is an internal hex bolt (made of stainless steel), which is screwed horizontally into the side of the mounting base 1 and threaded to the side wall of the fixing groove 11. The end of the knob presses against the side of the bar magnet 2 to prevent the magnet from shifting during vibration. Preferably, a nylon anti-loosening washer is added to the end of the knob.

[0039] It is worth noting that a threaded hole is provided on the side of the bar magnet 2, and the second locking knob 5 is screwed into this hole. The top of this knob abuts against the side of the positioning pin 3, and the extension height of the positioning pin 3 is controlled by the depth of screwing (adjustment range 5-10mm). This design can accommodate ball heads 6 with different depths of the round hole 601, such as shallow hole type (3mm deep) or deep hole type (8mm deep).

[0040] Preferably, two parallel fixing slots 11 are arranged, with a spacing matching the width of the standard ball head 6 (approximately 80mm). Each slot contains a strip magnet 2, and the number of positioning pins 3 is increased to two accordingly. The magnet layout supports bidirectional placement of the ball head 6 (e.g., left and right). Figure 4 and Figure 5 (As shown), this shortens the loading and unloading time.

[0041] To prevent axial slippage of the magnet, a limiting step 131 with a height of approximately 2mm is machined at the upper end of the vertical part 13. This step intersects perpendicularly with the top surface of the horizontal part 12. After the bar magnet 2 is embedded in the fixing groove 11, its second end (tail end) is tightly attached to the side of the step. In this way, even if the ball head 6 is frequently replaced, the position of the magnet remains stable, ensuring that the coaxiality error between the positioning pin 3 and the circular hole 601 of the ball head 6 is ≤0.1mm.

[0042] Finally, two locking holes 132 with a diameter of 10mm are provided on the vertical part 13. The locking holes 132 penetrate the front and rear surfaces of the vertical part 13, and the fixture is fixed to the welding table by M8 bolts. Preferably, the table surface has a pre-embedded T-slot nut, but a vacuum suction cup fixing method can also be used to adapt to non-metallic table surfaces.

[0043] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
