Description

Technical Field

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

[0002] In the golf ball manufacturing process, removing or finely finishing the parting line (mold line) on the ball's surface caused by the mold parting surface is a crucial post-processing step. Residual mold lines not only affect the ball's aesthetics but also significantly impair its aerodynamic performance during flight, leading to unstable flight paths, reduced distances, and directly impacting the player's experience and performance.

[0003] Traditional methods of processing mold lines often rely on manual hand-held grinding of the ball on a belt sander or grinding wheel, or the use of simple rotating jigs. These methods have significant drawbacks: First, manual operation makes it difficult to ensure stable positioning of the ball during the grinding process. Hand tremors or uneven force can easily cause the ball to deflect or vibrate, resulting in uneven grinding, over-grinding, or localized missed areas, leading to poor product consistency and a high scrap rate. Second, manual operation is inefficient and labor-intensive, making it difficult to meet the needs of large-scale production. Third, while simple jigs can fix the ball, they often lack stable and controllable holding force and make it difficult to precisely control the movement trajectory of the grinding tool relative to the mold line, resulting in unstable processing accuracy and difficulty in improving yield.

[0004] Therefore, designing a specialized device that can quickly, stably, and accurately clamp golf balls and effectively suppress ball displacement and vibration during the grinding process, thereby ensuring high precision, high efficiency, and good consistency in die grinding, has become a key technical problem that urgently needs to be solved to improve the manufacturing quality and production efficiency of golf balls. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a single-layer golf ball edge grinding machine. Through a rotating ball support and pressure seat, a stable and controllable bidirectional rotating clamp is formed under the action of a pressure drive, directly solving the problems of ball shaking, deflection, and uneven force application caused by manual operation or simple clamps. The rotary drive drives the rotating ball support, pressure seat, and ball to rotate at a uniform speed. Combined with a sliding edge grinding mechanism located at the processing gap, it performs precise trajectory grinding of the mold line, completely eliminating uneven grinding, over-grinding, or under-grinding phenomena. This significantly improves processing accuracy, efficiency, and product consistency, and reduces the scrap rate.

[0042] The present invention will now be described in detail with reference to the accompanying drawings.

[0043] like Figures 1 to 3 As shown, the present invention provides a single-layer golf ball edge grinding machine, comprising a frame 1, a rotating ball bearing seat 2, a rotating drive 3, a ball pressing seat 4, a pressing drive 5, and an edge grinding mechanism 6.

[0044] The rotating ball support 2 is rotatably mounted on the frame 1 to support and rotate the golf ball. By supporting the golf ball with the rotating ball support 2, the golf ball rotates around its own axis. This ensures that the golf ball's grooves are fully exposed and pass through the grinding station at a uniform speed, guaranteeing uniform grinding of the grooves in the circumferential direction.

[0045] The rotary actuator 3 is fixed to the frame 1 and is used to drive the rotary ball bearing seat 2 to rotate; the rotary actuator 3 drives the rotary ball bearing seat 2 to rotate stably. Providing stable and controllable rotational motion for the ball is the basis for achieving uniform grinding. The rotary actuator 3 is a motor.

[0046] The pressure ball seat 4 is rotatably positioned directly above the rotary ball bearing seat 2; by being positioned directly above the rotary ball bearing seat 2, the pressure ball seat 4 applies pressure to the upper surface of the ball. Together with the rotary ball bearing seat 2, it forms an upper and lower clamping mechanism, fixing the position of the ball and suppressing runout and deflection during processing.

[0047] The holding actuator 5 is mounted on the frame 1 and is used to drive the ball-holding seat 4 to hold the golf ball on the swivel bearing seat 2; the holding actuator 5 drives the ball-holding seat 4 to apply a holding force to the golf ball. This provides a stable and controllable holding force, ensuring the ball is reliably fixed during processing and avoiding vibration or displacement caused by uneven force application. The holding actuator 5 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0048] Both the rotating ball bearing seat 2 and the pressure ball seat 4 are rotatably configured, allowing the ball to rotate smoothly while pressing it, thus avoiding the ball from getting stuck or its surface damaged due to high frictional resistance.

[0049] A machining gap 7 is left between the rotating ball bearing seat 2 and the pressure ball seat 4; the machining gap 7 provides the necessary operating space for the grinding mechanism 6 to approach and grind the equatorial surface of the ball (the location of the mold line), while limiting the displacement of the ball in the vertical direction.

[0050] The edge grinding mechanism 6 is slidably mounted on one side of the rotating ball bearing seat 2 and is used to grind the mold lines of the golf ball within the processing gap 7. The edge grinding mechanism 6 can move along a set trajectory, allowing it to precisely feed or adjust its position along the ball's mold line trajectory, achieving precise and controllable grinding of the mold lines.

[0051] The working process of this single-layer golf ball edge grinding machine is as follows:

[0052] Clamping and positioning: Place the golf ball on the swivel bearing seat 2. The clamping driver 5 drives the pressure seat 4 to move downward, stably clamping the golf ball between the swivel bearing seat 2 and the pressure seat 4. Both the swivel bearing seat 2 and the pressure seat 4 are rotatably configured to ensure that the ball is firmly clamped while being able to rotate freely, and the equator (mold line position) of the ball is located in the machining gap 7 between the swivel bearing seat 2 and the pressure seat 4.

[0053] Ball rotation: The rotary driver 3 is activated, driving the rotary ball bearing seat 2 to rotate at a constant speed, which in turn causes the clamped golf ball and the ball bearing seat 4 to rotate around the central axis of the golf ball.

[0054] Mold line grinding: The grinding mechanism 6, located on one side of the rotating ball bearing seat 2, precisely aligns with and contacts the mold line of the rotating golf ball (located within the processing gap 7) by sliding adjustment. As the ball rotates at a uniform speed, the mold line on the entire circumference of the golf ball is ground uniformly in sequence.

[0055] Processing complete: After the mold line grinding meets the requirements, the grinding mechanism 6 retracts, the rotary driver 3 stops rotating, the holding driver 5 drives the ball pressing seat 4 to rise and release the ball, and the processed golf ball is taken out.

[0056] like Figures 1 to 3 As shown, in this embodiment, a lifting cylinder 21 and a lifting driver 22 are provided on the outer side of the rotating ball bearing seat 2.

[0057] The inner diameter of the lifting cylinder 21 is smaller than the diameter of the golf ball. The lifting cylinder 21 is located outside the rotating ball bearing seat 2 and slides along the axis of the rotating ball bearing seat 2. When the lifting cylinder 21 is raised, it is used to position the golf ball on the rotating ball bearing seat 2. When the lifting cylinder 21 is lowered, it is used to expose the machining clearance 7. When the lifting cylinder 21 is raised, it acts as a positioning guide sleeve, and when it is lowered, it is disengaged. When the ball is placed, the raised lifting cylinder 21 restricts the radial movement of the ball, ensuring that the ball is accurately positioned at the center of the rotating ball bearing seat 2 and avoiding manual placement deviation. After it is lowered, the machining clearance 7 is fully exposed, providing unobstructed grinding space for the edge grinding mechanism 6.

[0058] The lifting actuator 22 is used to drive the lifting cylinder 21 to rise and fall. This enables the position switching of the lifting cylinder 21 (raising the positioning ball -> lowering to expose the machining gap 7), improving clamping and positioning accuracy and efficiency. The lifting actuator 22 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0059] like Figure 1 and Figure 2 As shown, in this embodiment, the frame 1 is equipped with a protective cover 11 corresponding to the ball-pressing seat 4. The ball-pressing seat 4 is separated from the golf ball and concealed within the protective cover 11. This effectively isolates the rotating or lifting ball-pressing seat 4, preventing operators from accidentally contacting moving parts and reducing the risk of workplace injuries. It also prevents the ball-pressing seat 4 from being exposed to the external environment or damaged by accidental collisions when not in operation, thus improving the durability of the equipment.

[0060] like Figure 3 As shown, the edge grinding mechanism 6 in this embodiment includes a translation driver 61, a rotation driver 62, and a grinding disc 63;

[0061] A translation actuator 61 is mounted on the frame 1 and is used to drive the rotary actuator 62 to move closer to or away from the processing gap 7. The translation actuator 61 drives the entire edge grinding mechanism 6 to move linearly along the direction closer to or away from the processing gap 7. It precisely controls the radial feed depth of the grinding disc 63 relative to the rotating golf ball's groove, ensuring controllable grinding amount, avoiding over-grinding or under-grinding, and enabling quick avoidance for easy ball loading and unloading. The translation actuator 61 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0062] A rotary driver 62 is mounted on a translational driver 61 and is used to drive the grinding disc 63 to rotate. By driving the grinding disc 63 to rotate at high speed, the rotary driver 62 provides stable grinding power to the grinding disc 63, achieving efficient and continuous grinding and significantly improving grinding efficiency. The rotary driver 62 is an electric motor.

[0063] The grinding disc 63 is provided with a grinding surface 631 in the circumference, which is used to grind the circumference of the golf ball. The circumferential grinding surface 631 can form a full circumferential contact with the circumference (equatorial circumference) of the rotating ball, ensuring that all points on the circumference of the circumference receive a uniform grinding effect and eliminating missed grinding or local insufficient grinding.

[0064] like Figure 3 As shown, a dust collection hood 8 is provided on one side of the grinding disc 63 in this embodiment. The dust collection hood 8 is closely adjacent to the grinding area. During the grinding process of the grinding disc 63, the dust and debris splashed are captured in real time, suppressing the spread of dust from the source, effectively keeping the working environment clean, avoiding dust pollution of equipment or affecting the processing line of sight, and ensuring the health and safety of the operators.

[0065] like Figure 3 As shown, the dust hood 8 in this embodiment includes a base box 81, a dust collection pipe 82, and a suction pipe 83;

[0066] The base box 81 is located below the grinding disc 63. A dust collection pipe 82 is connected to one side of the base box 81, and a suction pipe 83 is connected to the side of the dust collection pipe 82 furthest from the base box 81. This creates a dust channel by connecting one side of the dust collection pipe 82 to the base box 81 and the other side to the suction pipe 83. Through the three-stage synergy of the base box 81 receiving the dust at its source, the dust collection pipe 82 guiding and converging the dust, and the suction pipe 83 drawing in dust under negative pressure, efficient and centralized collection and removal of grinding dust is achieved. This completely solves the problems of dust pollution, obstruction of processing visibility, and harm to operator health, ensuring a clean and safe working environment.

[0067] In actual use, the suction pipe 83 is connected to an external negative pressure device, enabling the suction pipe 83 to have a negative pressure suction function.

[0068] like Figure 2 As shown, a ball-blowing nozzle 23 is provided on one side of the rotating ball bearing seat 2 in this embodiment;

[0069] The ball-blowing nozzle 23 is connected to an external compressor and is used to blow away the golf ball placed on the rotating ball bearing seat 2. High-speed airflow is generated using compressed air. After processing, when the ball bearing seat 4 rises to release the golf ball, the airflow from the ball-blowing nozzle 23 acts directly on the surface of the ball, quickly and automatically blowing the ball away from the rotating ball bearing seat 2 without manual contact, achieving efficient unloading.

[0070] like Figure 1 As shown, the frame 1 in this embodiment is equipped with a protective light grid 12 to prevent foreign objects from entering the processing gap 7. The infrared beam emitted / received by the protective light grid 12 forms one or more invisible optical barriers around the processing gap 7. When an operator's limbs, tools, or other foreign objects accidentally enter the processing gap 7 area and block the beam, the light grid immediately triggers an emergency shutdown of the equipment (such as stopping the rotation drive 3 and the edge grinding mechanism 6), completely eliminating the risk of personnel injury or equipment collision.

[0071] like Figure 3 As shown, both the rotating ball bearing seat 2 and the ball pressing seat 4 in this embodiment include a ball fixing groove 24 that conforms to the surface of the golf ball. By increasing the contact area and matching the curvature of the ball surface through the ball fixing groove 24, the clamping stability is significantly improved, effectively limiting the radial movement or circumferential slippage of the ball during rotation or grinding, and ensuring precise alignment of the rotation axis.

[0072] The ball-fixing groove 24 is provided with a ball-exposing perforation 25 that allows the golf ball to be exposed outside the ball-fixing groove 24. The ball-exposing perforation 25 allows the golf ball to be fully inserted into the ball-fixing groove and fitted into the ball-fixing groove 24.

[0073] 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.
