Description

Technical Field

[0001] This utility model relates to the field of golf ball manufacturing technology, and in particular to a multi-layer golf ball edge trimming and grinding machine. Background Technology

[0002] In golf ball manufacturing, the mold lines on the ball's surface are tiny protrusions formed by mold parting. These must be precisely removed and smoothed in post-processing to optimize the ball's flight stability, rolling performance, and durability.

[0003] Traditional processing methods typically rely on separate edge trimming and grinding processes. Golf balls require initial trimming of the mold lines on a separate edge trimming machine, followed by secondary grinding on a grinding machine. This process involves multiple manual clamping and position adjustments. This results in a lengthy and inefficient production process, and repeated clamping can introduce positioning errors, leading to uneven mold line processing, surface damage, or quality fluctuations.

[0004] Furthermore, the rotary drive mechanisms of existing equipment are often simple and rudimentary, making it difficult to guarantee the stability and concentricity of the ball's rotation. This is especially problematic during high-speed machining, where vibrations can easily occur, affecting accuracy. At the same time, insufficient automation and reliance on manual operation not only increase labor intensity and costs but also limit the consistency and scalability of production scale.

[0005] Therefore, the key technical problem that the industry urgently needs to solve is to develop a highly efficient integrated equipment that can automatically complete the continuous processing of edge trimming and grinding in one setting, in order to overcome the defects of low production efficiency, poor processing accuracy and inconsistent quality.

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-layer golf ball edge trimming and grinding machine. This machine uses a rotating ball-fixing assembly to clamp and drive the golf ball to rotate, precisely revealing the golf ball's mold line within the processing gap. This solves the positioning error problem caused by repeated clamping in traditional processes. The edge trimming mechanism cuts the golf ball's mold line within the processing gap, while the edge grinding mechanism grinds the cut area of ​​the golf ball. Continuous processing is completed on a single machine, avoiding the inefficiency of switching between multiple machines in traditional methods. The entire process operates stably under the support of the machine frame, ensuring uniform and consistent processing of the golf ball's mold line and eliminating quality fluctuations caused by manual intervention.

[0047] The present invention will now be described in detail with reference to the accompanying drawings.

[0048] like Figures 1 to 4 As shown, the present invention provides a multi-layer golf ball edge trimming and grinding machine, comprising a frame 1, a rotating ball-fixing assembly 2, an edge trimming mechanism 3, and an edge grinding mechanism 4.

[0049] The rotating ball-fixing assembly 2 is rotatably mounted on the frame 1 to clamp the golf ball and drive it to rotate along its own axis; the rotating ball-fixing assembly 2 is provided with a machining gap 5 that exposes the golf ball's mold line; this achieves reliable fixing and rotation drive of the golf ball, and exposes the mold line area through the machining gap 5 for processing.

[0050] The edge-cutting mechanism 3 is slidably disposed on one side of the rotating ball-fixing assembly 2 and is used to cut the mold lines of the golf ball within the processing gap 5; the edge-cutting mechanism 3 cuts away the mold lines exposed in the processing gap 5.

[0051] The edge grinding mechanism 4 is slidably disposed on the other side of the rotating ball-fixing assembly 2, and is used to grind the crease lines of the golf ball after cutting within the processing gap 5. By grinding the crease line area exposed in the processing gap 5 and after cutting through the edge grinding mechanism 4, the surface quality of the golf ball is improved.

[0052] The working process of this multi-layer golf ball edge trimming and grinding machine is as follows:

[0053] Fixing and Rotation: The golf ball to be processed is placed in the rotating ball-fixing assembly 2 and clamped in place. The rotating ball-fixing assembly 2 rotates on the frame 1, driving the golf ball to rotate stably along its own axis.

[0054] Exposed mold lines: During rotation, the mold lines (mold parting line protrusions) of the golf ball are always exposed in the specially designed machining gap 5 of the rotating ball-fixing assembly 2.

[0055] Cutting the mold line: The edge trimming mechanism 3 moves to the processing position on one side of the rotating ball assembly 2 and cuts the mold line that rotates with the ball within the processing gap 5 to remove the main protrusions of the mold line.

[0056] Grinding the mold lines: The grinding mechanism 4 moves to the processing position on the other side of the rotating ball-fixing assembly 2 and grinds the remaining mold lines in the processing gap 5 to achieve surface finishing of the golf ball.

[0057] The entire process is supported by the frame 1, and the ball is driven to rotate continuously by the rotating ball fixing assembly 2. With the sliding positioning and processing of the edge cutting mechanism 3 and the edge grinding mechanism 4, the cutting and grinding of the golf ball pattern is completed efficiently and continuously in a single clamping.

[0058] like Figure 2 As shown, the rotating ball-holding assembly 2 in this embodiment includes a rotating ball bearing seat 21, a rotating driver 22, a ball-pressing seat 23, and a pressing driver 24. The rotating driver 22 is a motor, and the pressing driver 24 is an electric cylinder or a pneumatic cylinder.

[0059] The rotating ball support 21 is rotatably mounted on the frame 1 to support and drive the golf ball to rotate; the rotating ball support 21 provides stable support and directly transmits the rotational motion to the golf ball.

[0060] The rotary actuator 22 is fixed to the frame 1 and is used to drive the rotary ball bearing seat 21 to rotate; it provides power to the rotary ball bearing seat 21 to realize the active rotation drive of the golf ball.

[0061] The ball bearing seat 23 is rotatably positioned directly above the rotating ball bearing seat 21; the ball bearing seat 23 and the rotating ball bearing seat 21 cooperate to form a clamping space.

[0062] The pressure drive 24 is mounted on the frame 1 and is used to drive the ball presser 23 to press the golf ball onto the swivel bearing seat 21; the pressure drive 24 provides downward pressure to ensure that the golf ball is firmly clamped between the swivel bearing seat 21 and the ball presser 23.

[0063] The machining gap 5 is located between the rotating ball bearing seat 21 and the ball pressing seat 23. The machining gap 5 is naturally formed when the golf ball is clamped, and the golf ball mold line is exposed through the machining gap 5 for machining.

[0064] The rotary ball bearing seat 21 is driven to rotate by the rotary driver 22, and the pressing seat 23 is driven to press down by the pressing driver 24. The golf ball is stably clamped between the rotary ball bearing seat 21 and the pressing seat 23 and rotates together with the rotary ball bearing seat 21. The machining gap 5 formed between the rotary ball bearing seat 21 and the pressing seat 23 precisely exposes the mold line area of ​​the golf ball to be processed.

[0065] like Figure 2 As shown, in this embodiment, a lifting cylinder 25 and a lifting driver 26 are provided on the outer side of the rotating ball bearing seat 21; wherein, the lifting driver 26 is a linear motor or a cylinder.

[0066] The inner diameter of the lifting cylinder 25 is smaller than the diameter of the golf ball. The lifting cylinder 25 is located outside the rotating ball bearing seat 21 and slides along the axis of the rotating ball bearing seat 21. When the lifting cylinder 25 is raised, it is used to position the golf ball on the rotating ball bearing seat 21. When the lifting cylinder 25 is lowered, it exposes the machining gap 5. When the lifting cylinder 25 is raised, it uses its own inner diameter to restrict the golf ball, achieving precise positioning. When the lifting cylinder 25 is lowered, it moves away to fully expose the machining gap 5 located between the rotating ball bearing seat 21 and the pressure seat 23. This facilitates the processing of the mold lines of the golf ball within the machining gap 5.

[0067] The lifting actuator 26 is used to drive the lifting cylinder 25 to rise and fall. The lifting actuator 26 provides power to the lifting cylinder 25, enabling it to rise, position the golf ball, and descend, thus achieving precise motion control to expose the machining gap 5. This provides unobstructed operating space for subsequent edge trimming and grinding processes.

[0068] like Figure 2 As shown, in this embodiment, the frame 1 is equipped with a protective cover 11 corresponding to the ball-pressing seat 23. The ball-pressing seat 23 is separated from the golf ball and housed within the protective cover 11. The protective cover 11 provides a space for the ball-pressing seat 23 when it is not in use (when separated from the ball), preventing the ball-pressing seat 23 from being exposed to the external environment and causing interference or damage. This ensures that the ball-pressing seat 23 is effectively stored and protected when not in use, preventing external factors from affecting its positional accuracy or causing accidental collisions, while also keeping the work area clean.

[0069] like Figure 3 As shown, the edge trimming mechanism 3 in this embodiment includes a cutting tool 31, a tool holder 32, and a cutting driver 33; wherein, the cutting driver 33 is a linear motor or a cylinder.

[0070] The cutting tool 31 is fixed to the tool holder 32 and moves with the displacement of the tool holder 32; the tool holder 32 drives the cutting tool 31 to achieve precise displacement, so that the cutting tool 31 can directly perform the cutting operation on the golf ball pattern within the machining gap 5.

[0071] The tool holder 32 is slidably connected to the frame 1 and is used to support the tool 31. It provides a mounting base for the tool 31 and allows for adjustment of the overall position of the tool 31 through sliding.

[0072] The cutting driver 33 drives the tool holder 32 to move closer to or further away from the machining gap 5. The cutting driver 33 provides power to the tool holder 32 and controls the tool 31 to enter the machining gap 5 for cutting or to withdraw from the gap to stop machining.

[0073] In use, the cutting driver 33 drives the tool holder 32 to slide along the frame 1, which in turn drives the tool 31 fixed thereon to move synchronously. This allows the tool 31 to precisely approach the machining gap 5 to cut the exposed golf ball pattern, or move away from the gap to avoid the ball. This ensures that the cutting process is controllable and the operation is flexible.

[0074] like Figure 3 As shown, in this embodiment, the blade holder 32 has mounting grooves 321 on both sides, and pressure rollers 322 are rolled within the mounting grooves 321. Friction cone surfaces 323 are provided on opposite sides of the two pressure rollers 322. The friction cone surfaces 323 contact the surface of the golf ball, causing it to rotate passively with the ball, thus providing a limiting effect. The friction cone surfaces 323 provide a contact surface adapted to the curved surface of the golf ball, ensuring stable contact and follow-up rotation.

[0075] The friction cone surface 323 of the pressure roller 322 contacts the golf ball and rotates with the rotating golf ball to prevent the cutter 31 from over-cutting the golf ball.

[0076] When the tool holder 32 moves the tool 31 close to the machining clearance 5 for cutting, the pressure rollers 322, which are located in the mounting grooves 321 on both sides of the tool holder 32, simultaneously abut against the surface of the rotating golf ball through their own friction cone surfaces 323. The pressure rollers 322 rotate with the golf ball, forming a physical limit to prevent the tool 31 from over-cutting the golf ball due to excessive feed depth, thus ensuring machining accuracy and the integrity of the ball.

[0077] like Figure 3 As shown, the tool holder 32 in this embodiment is provided with a chip removal groove 324, and the tool 31 is provided with a cutting part 311, which is exposed in the chip removal groove 324.

[0078] In use, the chip removal groove 324 provided by the tool holder 32 provides a path for the chips generated during the cutting process; at the same time, the cutting part 311 of the tool 31 is precisely exposed in the chip removal groove 324, ensuring that the cutting operation is carried out directly in the chip removal space, so that the chips fall into the groove immediately and are guided away from the processing area, preventing the accumulation of chips from interfering with the cutting process or damaging the surface of the ball.

[0079] like Figure 3As shown, the cutting tool 31 in this embodiment is equipped with a micrometer 34, which is fixed to the tool holder 32 and abuts against the cutting tool 31. The micrometer 34 is used to adjust the position of the cutting part 311 within the chip removal groove 324. The micrometer 34 is fixedly mounted on the tool holder 32 and transmits displacement through mechanical contact with the cutting tool 31. By operating the micrometer 34 for fine-tuning, the displacement of the connected cutting tool 31 can be precisely controlled, thereby adjusting the position of the cutting part 311 within the chip removal groove 324. This achieves precise control of the cutting depth and ensures machining accuracy.

[0080] like Figure 4 As shown, the edge grinding mechanism 4 in this embodiment includes a movable plate 41, a sanding belt 42, an edge grinding driver 43, and a translation driver 44; wherein, the edge grinding driver 43 is a motor, and the translation driver 44 is a linear motor or a cylinder.

[0081] The movable plate 41 is slidably connected to the frame 1. The movable plate 41 is provided with a drive wheel and a winding wheel, and the sanding belt 42 is set between the drive wheel and the winding wheel.

[0082] The edge grinding driver 43 is used to drive the drive wheel to rotate;

[0083] Translation driver 44 is used to drive movable plate 41 to move closer to or away from machining gap 5.

[0084] The translation driver 44 drives the movable plate 41 to slide along the frame 1, causing the abrasive belt 42, which is sleeved between the drive wheel and the winding wheel, to move closer to or away from the processing gap 5. At the same time, the edge grinding driver 43 drives the drive wheel to rotate, causing the abrasive belt 42 to circulate and grind the golf ball pattern lines within the processing gap 5. This achieves precise control of the grinding position and start / stop.

[0085] like Figure 4 As shown, the frame 1 in this embodiment is provided with a protective light grid 12 to prevent foreign objects from entering the processing gap 5. By providing the protective light grid 12 on the frame 1, the protective light grid 12 prevents external foreign objects from entering the processing gap 5 area, ensuring the safety and cleanliness of the processing process.

[0086] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
