Description

Technical Field

[0001] This invention relates to the field of grinding technology, and in particular to a fluid grinding process. Background Technology

[0002] In traditional techniques, the surface polishing of metal accessories for smart wearables such as smartwatches, mobile phone casings, jewelry, and eyeglass frames is generally done manually. This process has many drawbacks, such as low polishing efficiency, inability to handle small surface areas, and poor stability and consistency in polishing quality, which is limited by the skill and proficiency of the operators. To achieve the required smoothness of the product surface, the processing usually involves first using a robotic arm for rough polishing, followed by fine polishing using a fluid grinding machine.

[0003] Fluid polishing machines utilize the high-speed collision between fluid abrasive and the workpiece surface to produce a grinding effect. Compared with traditional manual polishing, this represents a significant improvement. However, existing polishing machines rotate in the same direction, resulting in relatively low polishing efficiency. Polishing an irregularly shaped curved surface typically takes 1 to 6 hours. Furthermore, the polishing quality is limited and cannot meet higher surface treatment requirements. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a fluid grinding process.

[0005] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide a fluid grinding process, wherein an automated or manual grinding device and a fluid grinding device are used to process the surface of a product, the fluid grinding device including a grinding mechanism and an abrasive tank that move in opposite directions or back to back, the grinding mechanism including a second driving mechanism capable of driving the product to rotate and revolve simultaneously, the abrasive tank being used to hold the abrasive, and the process including the following steps:

[0006] S100: Place the product to be polished on the fixture and use an automated or manual polishing device to polish the surface of the product; wherein the product has an upper surface, a side surface and a lower surface, and the automated or manual polishing device polishes the upper surface, the side surface and the lower surface of the product respectively. When polishing each surface, the automated or manual polishing device is in a clockwise or counterclockwise direction.

[0007] S200: Remove the product from the fixture and place it into the fluid grinding device. Fix the product on the grinding mechanism and move the grinding mechanism and the abrasive barrel towards each other, so that the product extends into the abrasive barrel. The second drive mechanism drives the product to rotate to generate friction with the abrasive.

[0008] Furthermore, the fixture includes a base and a support portion disposed on the upper end of the base. The support portion is composed of an upper first portion and a lower second portion. The first portion matches the inner peripheral wall of the product, and the outer diameter of the second portion is larger than the outer diameter of the first portion and smaller than the outer diameter of the product. In step S100, when the product to be polished is placed on the fixture, the lower end of the product is placed on the upper end surface of the second portion, and the inner wall surface of the product is in contact with the outer wall surface of the first portion.

[0009] Furthermore, the grinding mechanism also includes a flat plate, a turntable, and a rotating shaft vertically disposed on the lower end face of the turntable for placing the product to be processed. The turntable is rotatably disposed on the flat plate, and the second driving mechanism is disposed between the turntable and the flat plate. In step S200, the product is fixed on the rotating shaft, and the grinding mechanism and the abrasive barrel move towards each other so that the product on the rotating shaft contacts the abrasive in the abrasive barrel. The second driving mechanism drives the turntable to rotate so that the rotating shaft revolves around the center of the turntable. At the same time, the second driving mechanism drives the rotating shaft to rotate so that the product rotates on its own axis while revolving around the turntable.

[0010] Furthermore, the second drive mechanism includes a first gear, a second gear, and a second motor. The first gear is fixed to the lower end face of the plate, and the second motor is located on the upper end face of the plate at a position corresponding to the axis of the first gear.

The second gear has several shafts corresponding one-to-one. Each second gear is fixed to the upper end of one rotating shaft, and each second gear meshes with the first gear. In step S200, the second motor rotates, driving the turntable to rotate. The several rotating shafts revolve around the center of the turntable, and at the same time, the rotating shafts rotate on their own axis under the cooperation of the first gear and the second gear, thereby allowing the product on the rotating shaft to fully rub against the abrasive.

[0011] Furthermore, the fluid grinding device also includes a frame, which includes an operating table, a support rod, and a top plate. The support rod is vertically disposed on the upper surface of the operating table, and the top plate is horizontally disposed on the upper end of the support rod. The abrasive barrel is disposed on the operating table, and the grinding mechanism is mounted on the support rod via a first drive assembly and moves closer to or away from the abrasive barrel.

The screw is vertically disposed between the operating table and the top plate and can rotate relative to the operating table and the top plate. The first motor is disposed on the operating table, and the output shaft of the first motor extends out and is drivenly connected to the screw. The plate is threadedly connected to the screw and slidably connected to the support rod. In step S200, the first motor drives the screw to rotate, thereby moving the plate up and down to realize the movement of the polishing mechanism, driving the product to move up and down back and forth, and polishing the product in the vertical direction.

[0013] Furthermore, the fluid grinding device also includes an air blowing assembly disposed between the grinding mechanism and the abrasive mechanism. The upper surface of the operating table is recessed downwards to form a cavity. The cavity includes a first cavity, the inner diameter of which matches the outer diameter of the abrasive barrel for placement within it. The cavity also includes a second cavity, formed by a radial outward recess from the inner wall of the first cavity. The second cavity is located at the end of the first cavity near the grinding mechanism. The air blowing assembly is disposed within the second cavity. The process further includes the following steps:

[0014] S300: The grinding mechanism moves in opposite directions from the abrasive barrel to remove the product. During the movement, the air blowing component sprays air onto the product to clean the product surface.

[0015] Furthermore, the air blowing assembly includes a plurality of fans and a third drive mechanism, wherein the plurality of fans rotate around the polishing mechanism under the drive of the third drive mechanism; in step S300, the plurality of fans rotate to perform air jet cleaning on the product.

[0016] Furthermore, the third drive mechanism includes a rotating ring, a third gear, and a fourth gear. The rotating ring is matched with the second cavity and rotatably disposed within the second cavity. A plurality of the fans are disposed on the rotating ring. The first motor is disposed within the operating table, and the drive shaft of the first motor extends upward and is connected to the screw drive. The third gear is disposed on the drive shaft of the first motor. The fourth gear is located on the same plane as the third gear and meshes with the third gear. A plurality of protruding teeth are provided on the outer circumference of the rotating ring, and the plurality of protruding teeth mesh with the fourth gear.

[0017] Furthermore, the inner peripheral wall of the rotating ring is radially recessed to form a groove for mounting the fan, and the lateral sides of the fan are rotatably connected to the lateral side walls of the groove; in step S300, the pitch angle of the fan can be changed to spray cleaning products from different angles.

[0018] Furthermore, it also includes a controller that is signal-connected to the first motor, the fan, and the second motor.

[0019] The fluid grinding device of the present invention has at least the following beneficial effects: first, a robotic arm performs rough grinding, and then the fluid grinding device performs fine grinding. The fluid grinding device can control the rotating shaft to drive the product to revolve around the center of the circle while rotating on its own axis, so that the product's movement trajectory is curved. The vibration of the abrasive barrel and the curved movement of the product can make the abrasive present a vortex state, so that the product and the abrasive have strong friction to achieve the polishing effect. Moreover, this process is dust-free polishing. After grinding, the product can be cleaned by blowing air with a blower. The fluid grinding device in this process is also equipped with an air blowing component. The blower in the air blowing component can change the pitch angle as the product moves up and down. At the same time, several blowers can rotate around the product, so that the product can be blown more thoroughly without dead angles, achieving a better cleaning effect. Attached Figure Description

[0045] A fluid grinding process of the present invention, which grinds product 1 using the aforementioned coarse grinding device 2 and fluid grinding device 3, includes the following steps:

[0046] S100: Place the product 1 to be polished on the fixture 21, and use the robot arm 22 to polish the surface of the product 1; wherein, the product 1 has an upper end surface, a side surface and a lower end surface, and the robot arm 22 polishes the upper end surface, the side surface and the lower end surface of the product 1 respectively. When polishing each surface, the robot arm 22 is in a clockwise or counterclockwise direction.

[0047] S200: Remove product 1 from fixture 21 and place it into the fluid grinding device 3. Fix product 1 on grinding mechanism 32 and move grinding mechanism 32 and abrasive barrel 34 towards each other, so that product 1 extends into abrasive barrel 34. The second drive mechanism drives product 1 to rotate to generate friction with abrasive. At the same time, the first drive mechanism 33 drives product 1 to move up and down continuously to polish product 1 in the vertical direction.

[0048] S300: The polishing mechanism 32 moves in opposite directions from the abrasive barrel 34 to remove the product 1. During the movement, the air blowing component 35 sprays air onto the product 1 to clean the surface of the product 1.

[0049] One embodiment of the fluid grinding process of the present invention operates as follows: In step S100, the product 1 to be ground (hereinafter referred to as product 1) is first placed on the fixture 21, specifically on the support portion, so that the lateral sides and the upper end of the second portion 213 provide support to the lateral sides of the product 1, while the first portion 212 supports the interior of the product 1. Please refer to... Figure 2 The robotic arm 22 is driven to move, thereby driving the polishing block 221 to polish the product 1. During polishing, the upper surface, side surface, and lower surface are polished sequentially. When polishing each surface, the robotic arm 22 drives the polishing block 221 to polish around the contour of the product 1 in a clockwise or counterclockwise direction. This three-stage polishing (top, middle, and bottom) aims to remove tool marks (left from the previous processing step) from the surface of the product 1. During the polishing process, water from an external water source flows through the water pipe 231 and the hose 232 to the robotic arm 22, cooling the polishing block 221 and the product 1, and simultaneously washing away the polishing debris. The water then falls into the receiving groove 233 and flows into the water bucket 234 through the short pipe.

[0050] In step S200, product 1 is fixed to the rotating shaft 323 by a protrusion. The first motor 332 is driven to rotate forward, which in turn drives the screw 331 to rotate forward. Under the limiting cooperation of the support rod 312 on the plate 321, the plate 321 moves downward with the rotation of the screw 331 until the rotating shaft 323 extends into the abrasive barrel 34, so that product 1 is completely buried in the abrasive in the abrasive barrel 34. The second motor 326 is started, which drives the turntable 322 to rotate. The turntable 322 drives several rotating shafts 323 to revolve around the axis of the turntable 322. At the same time, under the meshing and matching of the first gear 324 and the second gear 325, several rotating shafts 323 rotate simultaneously, which allows product 1 to have more sufficient contact with the abrasive. During polishing, the first drive mechanism 33 drives the product 1 to move up and down back and forth to polish the dead corners of the product 1 and the upper and lower surfaces of the workpiece, so as to achieve the function of polishing the product 1 without dead corners.

[0051] In step S300, product 1 comes into full contact with and rubs against the abrasive, removing the tool marks on the surface of product 1. At this point, the first motor 332 is driven to reverse, causing the screw 331 to reverse as well, moving the plate 321 upward until product 1 leaves the abrasive barrel 34. Initially, the blower 351 is tilted downward, meaning it blows air diagonally downward. As the plate 321 moves product 1 upward, it drives the metal slider 356 upward within the support rod 312 via the magnet 359. When the slider 356 moves upward, it compresses the gas located above the slider 356 inside the support rod 312, causing this gas to enter the annular airbag 358 through the air pipe 357. The annular airbag 358 inflates and protrudes downwards from the third cavity into the annular groove 3521, pressing down the rear end of the fan 351. This causes the fan 351 to gradually rotate from an angled downward opening to a horizontal position and then back to an angled upward opening. In other words, the airflow direction of the fan 351 rises as the product 1 is raised, ensuring that the airflow is always directed onto the product 1 and to different locations within it, achieving a better cleaning effect. Simultaneously, when the first motor 332 rotates, its power is transmitted to the rotating ring 352 via the third gear 353 and the fourth gear 354, causing it to rotate. The rotating ring 352 drives several fans 351 to rotate, blowing air onto the product 1 in different directions for an even better cleaning effect.

When polishing each surface, the automated or manual polishing device moves in a clockwise or counterclockwise direction. S200: Remove the product from the fixture and place it into the fluid grinding device. Fix the product on the grinding mechanism and move the grinding mechanism and the abrasive barrel towards each other so that the product extends into the abrasive barrel. The second drive mechanism drives the product to rotate to generate friction with the abrasive. S300: The grinding mechanism moves in opposite directions from the abrasive barrel to remove the product. During the movement, the first motor drives the grinding mechanism to move upward, and the grinding mechanism drives the slider to move upward via a magnet. Gas is pressed into the annular airbag through the air pipe to expand and press down on the rear end of the blower to change the pitch angle of the blower. At the same time, the first motor drives the rotating ring to rotate via the third and fourth gears, and several blowers rotate to spray air to clean the product.

2. The fluid milling process as described in claim 1, characterized in that: The fixture includes a base and a support portion located on the upper end of the base. The support portion consists of an upper first portion and a lower second portion. The first portion matches the inner peripheral wall of the product, and the outer diameter of the second portion is larger than the outer diameter of the first portion and smaller than the outer diameter of the product. In step S100, when the product to be polished is placed on the fixture, the lower end of the product is placed on the upper surface of the second portion, and the inner wall surface of the product is in contact with the outer wall surface of the first portion.

3. The fluid milling process as described in claim 1, characterized in that: The grinding mechanism also includes a flat plate, a turntable, and a rotating shaft vertically disposed on the lower end face of the turntable for placing the product to be processed. The turntable is rotatably disposed on the flat plate, and the second drive mechanism is disposed between the turntable and the flat plate. In step S200, the product is fixed on the rotating shaft, and the grinding mechanism and the abrasive barrel move towards each other so that the product on the rotating shaft contacts the abrasive in the abrasive barrel. The second drive mechanism drives the turntable to rotate so that the rotating shaft revolves around the center of the turntable. At the same time, the second drive mechanism drives the rotating shaft to rotate so that the product rotates on its own axis while revolving around the turntable.

4. The fluid milling process as described in claim 3, characterized in that: The second drive mechanism includes a first gear, a second gear, and a second motor. The first gear is fixed to the lower end face of the plate, and the second motor is located on the upper end face of the plate at a position corresponding to the axis of the first gear. The output shaft of the second motor passes downward through the plate and the first gear and is connected to a turntable. There are several rotating shafts distributed around the axis of the first gear. Each rotating shaft is rotatably connected to the turntable and passes upward through the turntable. There are several second gears corresponding one-to-one with the rotating shafts. Each second gear is fixed to the upper end of a rotating shaft, and each second gear meshes with the first gear. In step S200, the second motor rotates, driving the turntable to rotate. Several rotating shafts revolve around the center of the turntable, and at the same time, the rotating shafts rotate on their own axis under the cooperation of the first gear and the second gear, so that the product on the rotating shaft and the abrasive can fully rub against each other.

5. The fluid milling process as described in claim 4, characterized in that: The fluid grinding device also includes an operating table and a top plate. The support rod is vertically installed on the upper surface of the operating table, and the top plate is horizontally installed on the upper end of the support rod. The abrasive barrel is installed on the operating table, and the grinding mechanism is mounted on the support rod through the first drive mechanism and moves closer to or away from the abrasive barrel. The first driving mechanism also includes a screw, which is vertically positioned between the operating table and the top plate and rotates relative to the operating table and the top plate. A first motor is positioned on the operating table, with its drive shaft extending out and connected to the screw. The plate is threadedly connected to the screw and slidably connected to the support rod. In step S200, the first motor drives the screw to rotate, thereby moving the plate up and down to realize the movement of the polishing mechanism, driving the product to move up and down back and forth, and polishing the product in the vertical direction.

6. The fluid milling process as described in claim 5, characterized in that: The first motor is located inside the control panel, and its drive shaft extends upwards and is connected to the screw drive.

7. The fluid milling process as described in claim 6, characterized in that: It also includes a controller that is signal-connected to the first motor, the fan, and the second motor.
