Description

Technical Field

[0001] This utility model relates to the field of steel ball production technology, and more specifically, to a grinding device for steel ball production. Background Technology

[0002] In the existing steel ball production process, the grinding process is a key step in improving the surface precision and smoothness of the steel balls, which directly affects the performance and lifespan of the steel balls. However, the grinding equipment currently available on the market for steel ball production still has many technical defects in practical applications, making it difficult to meet the needs of efficient, precise and environmentally friendly production. First, traditional clamping structures often use rigid clamps, making it difficult to precisely control the clamping force. This can easily lead to indentations on the surface of the steel ball due to excessive clamping, or slippage and displacement of the steel ball during grinding due to excessive clamping, thus affecting the grinding accuracy. At the same time, it is impossible to flexibly adjust the angle of the steel ball according to the grinding requirements. For grinding the curved surface of the steel ball, multiple stops are required to adjust the clamping position, which is not only cumbersome to operate, but also prone to uneven grinding due to repeated positioning errors. Secondly, the grinding head of traditional grinding devices is usually fixed in position, making it difficult to adjust its position precisely according to the diameter of the steel ball or the different grinding areas. When fine grinding is required on different curved surfaces or specific areas of the steel ball, it is often necessary to replace different grinding components or adjust the overall structure of the device. This operation is complicated and time-consuming, which seriously restricts production efficiency. In addition, if the large amount of metal shavings generated during the grinding process are not cleaned in time, they will not only adhere to the surface of the grinding head and steel ball, affecting the grinding effect, but will also spread into the working environment, posing a threat to the health of operators and increasing the difficulty of subsequent equipment maintenance. Finally, traditional devices rely heavily on manual operation. After grinding, operators need to manually remove the steel balls from the clamping mechanism and put them into the storage container. This is not only labor-intensive, but also may cause the steel balls to become stained or suffer secondary damage due to manual contact. Especially for high-precision steel balls, manual storage can easily introduce impurities that affect their performance. Utility Model Content

[0006] The present invention is further configured such that the storage component includes a robotic arm and a robotic gripper, the robotic arm is located on one side of the center of the workbench, and the robotic gripper is located at the output end of the robotic arm, which can automatically remove the polished steel ball from the gripper without manual operation, thus reducing labor intensity.

[0007] The present invention is further configured such that symmetrical hooks are provided on the side wall of the workbench, and a storage box is provided at the hook.

[0008] The present invention is further configured such that an auxiliary frame is provided at one end of the workbench, and a camera is provided on the auxiliary frame, so that the operator can observe the grinding of the steel balls, detect abnormalities in time and make adjustments.

[0009] The present invention is further provided that the surface of the electric grinding disc is provided with a detachable grinding wheel, which is fixedly connected to the electric grinding disc by bolts, so as to adapt to different grinding needs and reduce replacement costs and time.

[0010] The present invention is further provided with a rubber pad on the inner side wall of the clamping claw, and the surface of the rubber pad is provided with anti-slip texture, which can increase the friction with the steel ball and prevent the steel ball from slipping and shifting during the grinding process.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a grinding device for steel ball production, which has the following beneficial effects: 1. From the perspective of the clamping and rotation of the steel ball, the symmetrically arranged support plates provide stable support for the rotating rod. The first motor drives the rotating rod to rotate the clamping claw, which can realize the multi-angle rotation of the steel ball. This facilitates the electric grinding disc to grind the steel ball in all directions, avoiding the problem of incomplete grinding caused by the fixed angle of the steel ball in traditional devices. The clamping claw is stable and reliable during rotation, ensuring that the steel ball will not deviate during grinding, thus providing a foundation for precise grinding.

[0012] 2. The cylinder on the support frame can drive the connecting plate to move up and down, thereby adjusting the height of the electric grinding disc to accommodate steel balls of different sizes; the electric push rod can push the electric grinding disc to move horizontally, making it easy to align with different grinding parts of the steel ball. This adjustable structure enables the device to meet the grinding needs of various specifications of steel balls without the need for frequent equipment replacement or complex structural adjustments, thus improving the versatility and efficiency of the equipment.

[0013] 3. The robotic arm can move flexibly, and its output end can accurately remove the polished steel balls from the gripper. The entire process requires no manual intervention, which not only reduces the labor intensity of operators, but also avoids surface contamination or damage that may be caused by manual contact with the steel balls, ensuring the surface quality of the steel balls. The hooks on the side wall of the workbench work with the storage box to provide a convenient storage space for the steel balls. The detachable connection between the storage box and the hook makes it easier to put in and take out the storage box and clean it, making the production site more tidy and orderly, and improving the efficiency of subsequent sorting and retrieval of steel balls.

[0014] 4. The dust extraction component plays an important role in the grinding process. It can promptly remove the metal shavings generated during grinding, preventing them from adhering to the surface of the steel balls or the electric grinding disc and affecting the grinding effect. It also prevents the shavings from spreading in the working environment, protecting the health of the operators, reducing wear and tear on the equipment, lowering the difficulty of equipment maintenance, and extending the service life of the equipment.

[0020] Please see Figure 1-5 A grinding device for steel ball production includes a workbench 1. A support box 2 is provided on one side of the upper end of the workbench 1. Symmetrical support plates 3 are provided on one side of the support box 2. Rotating rods 4 are provided on the inner side of each support plate 3. Clamping claws 5 are provided on one side of each rotating rod 4. A first motor 6 is provided on the outer side of the support plate 3. The other end of the rotating rods 4 is connected to the output end of the first motor 6. A support frame 7 is provided on the other side of the upper wall of the workbench 1. A cylinder 8 is provided at the center of the upper end of the support frame 7. A connecting plate 9 is provided at the lower end of the cylinder 8. An electric push rod 10 is provided at the lower end of the connecting plate 9. An electric grinding disc 11 is provided at one end of the electric push rod 10. A dust collection component is provided at the center of the upper wall of the workbench 1. A storage component is provided on one side of the workbench 1.

[0021] The storage assembly includes a robotic arm 16 and a robotic gripper 17. The robotic arm 16 is located on one side of the center of the workbench 1, and the robotic gripper 17 is located at the output end of the robotic arm 16.

[0022] The workbench 1 has symmetrical hooks 18 on its side wall, and a storage box 19 is provided at each hook 18. The storage box 19 is detachably connected to the hook 18.

[0023] The surface of the electric grinding disc 11 is provided with a detachable grinding wheel, which is fixedly connected to the electric grinding disc 11 by bolts.

[0024] In this embodiment, after the device is started, the steel ball is first clamped and fixed. The operator places the steel ball to be ground between two symmetrical clamping claws 5. The device starts the clamping program, and the clamping claws 5 close towards the center under the action of the drive mechanism until the steel ball is firmly clamped. At this time, the symmetrically arranged support plates 3 provide stable support for the rotating rod 4, ensuring a stable clamping state and laying the foundation for subsequent grinding. Next, the grinding stage begins. According to the size of the steel ball and the grinding requirements, the cylinder 8 on the support frame 7 is activated. The cylinder 8 pushes the connecting plate 9 to move up and down, thereby driving the electric push rod 10 and the electric grinding disc 11 to adjust their height so that they are aligned with the steel ball. Once the grinding position is matched and the height is adjusted, the electric push rod 10 is activated, pushing the electric grinding disc 11 to move horizontally until the grinding wheel on the surface of the electric grinding disc 11 is in contact with the part of the steel ball that needs to be ground. Then, the electric grinding disc 11 starts to rotate and grind the steel ball. During the grinding process, the first motor 6 is activated, driving the rotating rod 4 to drive the clamping claw 5 and the steel ball to rotate slowly, so that all surfaces of the steel ball can contact the grinding wheel, achieving all-round, no-dead-angle grinding. If it is necessary to adjust the grinding position, the horizontal position of the electric grinding disc 11 can be finely adjusted again by the electric push rod 10 to ensure that every part of the steel ball is precisely ground.

[0025] More specifically, during the grinding process, the dust extraction component at the center of the workbench 1 is activated simultaneously to promptly remove metal shavings generated during grinding, preventing shavings from adhering to the surface of the steel balls or the grinding wheel and affecting the grinding effect. This also keeps the working environment clean. Once the steel balls are ground, the electric grinding disc 11 stops rotating, the electric push rod 10 drives it to reset, and the cylinder 8 also drives the entire grinding mechanism to rise away from the steel balls. At this time, the gripper 5 releases the steel balls, and the storage component on one side of the workbench 1 begins to work. The robotic arm 16 is activated, driving the robotic claw 17 to move above the steel balls. The robotic claw 17 closes and clamps the ground steel balls. Then, the robotic arm 16 adjusts its position and transfers the steel balls to the storage box 19 on the side wall of the workbench 1. The robotic claw 17 releases, and the steel balls fall into the storage box 19 for storage. If it is necessary to store steel balls of different sizes separately, this can be achieved by changing different storage boxes 19. The detachable connection between the storage box 19 and the hook 18 makes the replacement process convenient and efficient.

[0026] Please see Figures 1-5As one embodiment of the vacuuming assembly: the vacuuming assembly includes an auxiliary plate 12, a control plate 13, a rotating shaft, and a vacuum cleaner 14. The auxiliary plate 12 connects the support box 2 and the upper end of the support frame 7. The control plates 13 are symmetrically arranged at the lower end of the auxiliary plate 12. The rotating shaft is between the two control plates 13. A connecting rod is provided on one side of the rotating shaft. The input end of the vacuum cleaner 14 is connected to the connecting rod. A second motor 15 is provided on the outer wall of one of the control plates 13. The rotating shaft is connected to the output end of the second motor 15.

[0027] Specifically, the auxiliary plate 12 connects the support box 2 and the upper end of the support frame 7. After the second motor 15 starts, it drives the rotating shaft between the two control plates 13 to rotate. The connecting rod on one side of the rotating shaft rotates accordingly, thereby driving the input end of the vacuum cleaner 14 to adjust the angle synchronously. This allows the input end of the vacuum cleaner 14 to accurately align with the grinding contact point between the steel ball and the grinding wheel. As the steel ball rotates and the grinding disc moves, the second motor 15 can adjust the rotation angle of the rotating shaft in real time, so that the input end of the vacuum cleaner 14 always follows the grinding area, efficiently sucking up the generated metal debris and avoiding debris accumulation that affects the grinding effect or pollutes the environment. The vacuum cleaner 14 is a common and mature technology on the market, and will not be elaborated on in this article.

[0028] Please see Figures 1-5 As one embodiment of the camera 21: an auxiliary frame 20 is provided at one end of the workbench 1, and the camera 21 is provided on the auxiliary frame 20.

[0029] Specifically, camera 21 will take pictures of the polished steel ball to record its final state, so as to compare it with the initial state and evaluate the polishing effect. At the same time, it can also supervise the transfer process of robotic arm 16 and robotic claw 17 to ensure that the steel ball is accurately placed into storage box 19.

[0030] Please see Figures 1-5 As one embodiment of the rubber pad: the inner wall of the clamping claw 5 is provided with a rubber pad, and the surface of the rubber pad is provided with anti-slip texture.

[0031] Specifically, the anti-slip texture on the surface of the rubber pad increases the friction between it and the steel ball, which can effectively prevent the steel ball from slipping or shifting in the clamping claw 5 even when the steel ball is rotating or subjected to a grinding force, ensuring a firm clamping.

[0032] In summary, when using the overall equipment: After the device is started, the steel ball is clamped and fixed. The operator places the steel ball to be polished between two symmetrical clamping claws 5. The clamping claws 5 close together in the middle under the action of the drive mechanism. Since the inner wall of the clamping claws 5 is equipped with a rubber pad and the surface of the rubber pad has anti-slip texture, the softness of the rubber pad allows it to deform slightly with the shape of the steel ball and fit tightly against the surface of the steel ball, avoiding indentation caused by rigid contact. The support plate 3 provides stable support for the rotating rod 4 to ensure stable clamping. At this time, the camera 21 on the auxiliary frame 20 at one end of the worktable 1 is activated to capture the initial state of the steel ball and the clamping position in real time, so as to keep a record of the polishing effect comparison.

[0033] After entering the grinding stage, according to the specifications of the steel balls, the cylinder 8 at the upper end of the support frame 7 drives the connecting plate 9 to move up and down through air pressure extension and retraction, adjusting the height of the electric grinding disc 11. After the height is adjusted to the correct position, the electric push rod 10 at the lower end of the connecting plate 9 is energized and extends, pushing the electric grinding disc 11 to move horizontally to the part of the steel ball to be ground. Subsequently, the grinding wheel on the surface of the electric grinding disc 11 rotates at high speed under the drive of the motor. The friction between the grinding wheel and the surface of the steel ball removes burrs and imperfections from the surface of the steel ball, achieving the grinding effect. At the same time, the first motor 6 on the outer side of the support plate 3 starts, and its output end drives the rotating rod 4 to rotate, thereby causing the steel ball held by the clamping claw 5 to rotate synchronously. By using the rotational power transmission of the motor, the steel ball can rotate 360 ​​degrees in all directions, ensuring that the grinding wheel can grind most of the area of ​​the steel ball.

[0034] During this process, the dust collection component on the workbench 1 simultaneously activates the auxiliary plate 12 to connect the support box 2 and the support frame 7, providing a stable installation base for the control board 13 and the rotating shaft; the second motor 15 drives the rotating shaft to rotate, and through the connecting rod, it drives the input end of the vacuum cleaner 14 to adjust the angle, always aligning it with the grinding area. Based on the principle of negative pressure, the suction force generated by the vacuum cleaner 14 sucks in the metal debris generated during grinding, avoiding the debris from affecting the grinding accuracy and working environment.

[0035] After most of the steel ball has been ground, if the initially clamped part is not ground because it did not contact the grinding wheel, the operator can manually turn off the device, remove the steel ball from the clamping jaw 5, then readjust the position of the steel ball, with the unground initially clamped part facing outwards, and put it back into the clamping jaw 5 to fix it. Repeat the above grinding process to ensure that the entire surface of the steel ball is evenly ground by manual supplementary grinding.

[0036] After all grinding is completed, the electric grinding disc 11 stops rotating, the electric push rod 10 retracts to reset, and the cylinder 8 also drives the grinding mechanism to rise away from the steel ball. The gripper 5 releases, the storage component on one side of the worktable 1 is activated, and the robotic arm 16 adjusts its position through multi-joint rotation. The robotic claw 17 at the output end of the robotic arm 16 closes under drive, transferring the steel ball from the gripper 5 to the storage box 19 on the side wall of the worktable 1. After the robotic claw 17 releases, the steel ball falls into the storage box 19. The storage box 19 is detachably connected to the worktable 1 via the hook 18 for easy removal of the steel ball later. Throughout the process, the camera 21 continuously monitors and records the grinding and transfer details to ensure precise operation. The grinding wheel on the surface of the electric grinding disc 11 is fixed by bolts. When the grinding wheel is worn or needs to be replaced with a different grit, the bolts can be loosened for replacement. The detachability of the threaded connection ensures the continuous use of the device.

[0037] In all the solutions mentioned above, the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although the embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents. In all the solutions mentioned above, the operation of electrical components is controlled by a controller. Since the devices matched with the controllers are common devices, their control principles and circuit connections are existing, well-known, and mature technologies. Therefore, their electrical connection relationships and specific circuit structures will not be elaborated here.
