Description

Technical Field

[0001] The invention belongs to the technical field of magnetic polishing equipment, and in particular relates to a magnetic polishing device for hardware parts. Background Art

[0002] The magnetic polishing machine is a highly efficient and environmentally friendly metal surface treatment equipment. It uses a high-speed rotating magnet to drive the abrasive (magnetic needle) to rotate, and uses the grinding effect of the magnetic needle and the workpiece to remove the microscopic protrusions and depressions on the surface of the processed material. It is a mechanical device, eliminates the oxide scale on the metal surface, improves the brightness of the metal surface, and removes scratches and other defects on the metal surface.

[0003] During magnetic polishing, not only abrasives (magnetic needles) but also water and brighteners need to be added to the grinding container. After grinding is completed, the abrasives (magnetic needles), workpieces, and water in the grinding container need to be poured out together, and then the abrasives (magnetic needles), workpieces, and water are separated from each other. The abrasives (magnetic needles) can be put back into the grinding container for reuse.

[0004] The turntable magnetic polishing device can continuously perform magnetic polishing on the workpiece when used with a feeder, saving manpower and improving production efficiency. However, the magnetic field of the current turntable magnetic polishing device is a horizontally rotating magnetic field, so that the abrasive (magnetic needle) can only polish the workpiece along the horizontal rotation under the action of the magnetic field. The polishing direction is relatively single, and it takes a long time to achieve the polishing requirements of the workpiece, resulting in low processing efficiency. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a magnetic polishing device for hardware parts, which at least partially solves the above problems.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a magnetic polishing device for hardware parts, including a machine table, a plurality of polishing barrels rotating circumferentially along the central axis of the machine table are arranged on the table top of the machine table, and a discharge port for discharging materials is arranged on one side of the machine table: A plurality of permanent magnetic discs are arranged below the tabletop of the machine and are distributed along the rotating path of the polishing barrel. The permanent magnetic discs are arranged to be rotatable and used to drive the magnetic needle in the polishing barrel to rotate horizontally. The polishing barrel is configured as a tubular shell with openings at both ends, the bottom open end of the polishing barrel is provided with a bottom cover that can be opened and closed, and the top open end of the polishing barrel is provided with a top cover that can be opened and closed; The top cover is provided with a plurality of circumferentially distributed electromagnets, which can exert a longitudinal magnetic attraction force on the horizontally rotating magnetic needle, so that the horizontally rotating magnetic needle flow produces longitudinal fluctuations.

[0007] Furthermore, both ends of the polishing barrel are provided with a flip cover mechanism for respectively controlling the opening and closing of the bottom cover and the top cover; The flip cover mechanism located at the bottom end of the polishing barrel can control the bottom cover to open, so that the material in the polishing barrel can be discharged from the bottom opening of the polishing barrel; The flip cover mechanism located at the top of the polishing barrel can control the top cover to open, and materials are added into the polishing barrel through the top opening of the polishing barrel.

[0008] Further, the flip cover mechanism includes a support ear, a connecting plate and an electric push rod, the support ear is fixed to one side of the polishing barrel, the connecting plate is hinged on the support ear, one end of the electric push rod is movably connected to the polishing barrel, and the other end of the electric push rod is connected to the connecting plate; The support ear close to the bottom cover is connected to the bottom cover, and the support ear close to the top cover is connected to the top cover.

[0009] Furthermore, a flip motor is provided on one side of the polishing barrel, and an output end of the flip motor is connected to a side wall of the polishing barrel; Before the polishing barrel opens the bottom cover to unload materials, the flip motor drives the polishing barrel and flips the two ends of the polishing barrel, so that the magnetic needle inside the polishing barrel is adsorbed on the top cover by the electromagnet.

[0010] Furthermore, a turntable is provided at the center of the machine, a driving motor for driving the turntable to rotate is provided under the table top of the machine, connecting frames corresponding to the number of polishing barrels are fixed on the turntable, and the flip motor is fixed on the connecting frame.

[0011] Furthermore, the top cover is provided with a plurality of drainage holes.

[0015] Furthermore, sealing rings are provided at the upper and lower opening ends of the polishing barrel.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: 1. An openable and closable top cover is set above the polishing barrel, and an electromagnet is set on the top cover. During the polishing process, the electromagnet is started, and the magnetic field generated by the electromagnet is used to apply a longitudinal magnetic attraction to the horizontally rotating magnetic needle, so that the horizontally rotating magnetic needle flow can produce longitudinal fluctuations. At this time, the magnetic needle flowing in the polishing barrel has multiple flow directions, which can rub the parts in multiple directions, thereby improving the polishing efficiency.

[0017] 2.

Then the polishing barrel will be flipped again, and the bottom cover will be opened for discharging. At this time, the non-magnetic parts are discharged, and the magnetic needle is adsorbed on the top cover by the electromagnet, completing the separation of the magnetic needle and the parts. When discharging, the magnetic needle will not be discharged together with the abrasive and parts. The operator does not need to separate the parts and the magnetic needle, and there is no need to re-add the magnetic needle to the polishing barrel. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0023] like Figure 1 and Figure 2 As shown, the present invention proposes a magnetic polishing device for hardware parts, including a machine platform 1, a permanent magnetic disc 11, a polishing barrel 2, a bottom cover 21, a top cover 22 and an electromagnet 23.

[0024] There are multiple polishing barrels 2, which rotate circumferentially along the central axis of the machine table 1. A plurality of permanent magnetic disks 11 distributed along the rotation path of the polishing barrel 2 are provided under the table top of the machine table 1. The permanent magnetic disk 11 can rotate around its own axis to generate a horizontally rotating magnetic field. The multiple circumferentially rotating polishing barrels 2 move along the distribution path of the permanent magnetic disk 11, and the polishing barrels 2 correspond to the permanent magnetic disk 11 one by one. The rotating permanent magnetic disk 11 drives the magnetic needle inside the polishing barrel 2 to rotate, and the surface of the part is polished by utilizing the friction between the magnetic needle and the part.

[0025] Furthermore, the diameter of the permanent magnetic disc 11 is larger than the diameter of the polishing barrel 2 , so that the magnetic field generated by the permanent magnetic disc 11 can completely cover the polishing barrel 2 , so that the magnetic needle in the polishing barrel 2 can be fully driven to rotate by the magnetic field.

[0026] In a specific embodiment, a motor bracket 13 is provided under the machine 1, and a plurality of disk motors 12 corresponding to the number of permanent magnet disks 11 are connected to the motor bracket 13. The output end of the disk motor 12 is connected to the permanent magnet disk 11, and the permanent magnet disk 11 is driven to rotate by the disk motor 12, so that a horizontally rotating magnetic field is formed above the machine 1. When the polishing barrel 2 moves to the magnetic field area, the magnetic needle inside the polishing barrel 2 is driven to rotate by the magnetic field, and the surface of the part is polished by the friction between the magnetic needle and the part.

[0027] The polishing barrel 2 is configured as a tubular shell with openings at both ends. The bottom open end of the polishing barrel 2 is provided with a bottom cover 21 that can be opened and closed, and the top open end of the polishing barrel 2 is provided with a top cover 22 that can be opened and closed. During the polishing process, the top cover 22 and the bottom cover 21 are both in a closed state, so that the openings at both ends of the polishing barrel 2 are sealed to prevent the rotating magnetic needle and abrasive from splashing outward.

[0028] In an optional embodiment, sealing rings are provided at both the upper and lower opening ends of the polishing barrel 2, which can improve the sealing performance of the bottom cover 21 and the top cover 22 when they are closed, thereby preventing leakage of the abrasive.

[0029] Furthermore, a discharge port 101 for discharging materials is provided on one side of the machine 1. When the polishing barrel 2 moves to the discharge port 101, the bottom cover 21 can be opened to discharge the materials in the polishing barrel 2 (such as Figure 5 As shown), after the material is discharged, the bottom cover 21 is closed again.

[0030] It should be noted that by setting a feeding mechanism on one side of the machine 1, when the polishing barrel 2 is discharged and moved back to the table of the machine 1 from the discharge port 101, the top cover 22 is opened and the feeding mechanism is used to add materials (such as Figure 6 As shown), after the feeding is completed, the top cover 22 is closed, and the polishing barrel 2 continues to rotate along the center circumference of the machine table 1 to polish the parts.

[0031] Combination Figure 1 As shown, both ends of the polishing barrel 2 are provided with a flip cover mechanism 3 for respectively controlling the opening and closing of the bottom cover 21 and the top cover 22; The flip cover mechanism 3 located at the bottom end of the polishing barrel 2 can control the bottom cover 21 to open, so that the material in the polishing barrel 2 is discharged from the bottom opening of the polishing barrel 2. The flip cover mechanism 3 located at the top end of the polishing barrel 2 can control the top cover 22 to open, and add material into the polishing barrel 2 through the top opening of the polishing barrel 2.

[0032] Combination Figure 3As shown, the flip mechanism 3 includes a support ear 31, a connecting plate 32 and an electric push rod 33. The support ear 31 is fixed on one side of the polishing barrel 2. The connecting plate 32 is hinged on the support ear 31 through a rotating shaft. One end of the electric push rod 33 is movably connected to the polishing barrel 2 through a hinge. The other end of the electric push rod 33 is connected to the connecting plate 32 through a rotating shaft. The support ear 31 close to the bottom cover 21 is connected to the bottom cover 21, and the support ear 31 close to the top cover 22 is connected to the top cover 22.

[0033] The electric push rod 33 can drive the connecting plate 32 to swing on the support ear 31. Since the bottom cover 21 and the top cover 22 are connected to the connecting plate 32 at corresponding positions, when the connecting plate 32 swings, the bottom cover 21 and the top cover 22 connected to the connecting plate 32 can swing, thereby realizing the opening and closing action.

[0034] In this way, the top cover 22 is opened by using the flip cover mechanism 3 at the corresponding position, the parts to be polished, the magnetic needles and the abrasives are added into the polishing barrel 2, and then the top cover 22 is closed, and the polishing barrel 2 moves along the distribution path of the permanent magnetic disc 11, and the polishing barrel 2 corresponds to the permanent magnetic disc 11 one by one. The rotating permanent magnetic disc 11 can drive the magnetic needles in the polishing barrel 2 to rotate, and the surface of the parts is polished by using the friction between the magnetic needles and the parts. When the polishing barrel 2 rotates one circle and moves to the discharge port 101, the bottom cover 21 is opened by using the flip cover mechanism 3 at the corresponding position, so that the materials in the polishing barrel 2 are discharged (such as Figure 5 As shown), after the material is discharged, the bottom cover 21 is closed again, and then the top cover 22 is opened, and the parts to be polished, the magnetic needles and the abrasive are added into the polishing barrel 2. The above steps are repeated for multiple polishing barrels 2, and the workpieces can be polished continuously. When used in conjunction with an automatic feeder, automatic loading, polishing and discharge of parts can be realized.

[0035] Combination Figure 3 , Figure 7 and Figure 8 As shown, the top cover 22 is provided with a plurality of circumferentially distributed electromagnets 23. When the electromagnets 23 are started, a plurality of magnetic fields distributed along the rotation direction of the magnetic needle are generated above the polishing barrel 2. The magnetic field generated by the electromagnets 23 exerts a longitudinal magnetic attraction on the horizontally rotating magnetic needle, causing the horizontally rotating magnetic needle flow to produce longitudinal fluctuations (such as Figure 8 As shown), at this time, the magnetic needle in the polishing barrel 2 can not only rotate and flow in the horizontal direction, but also flow in the longitudinal direction, rubbing the parts in multiple directions to improve the polishing efficiency.

[0036] In this way, during the polishing process, the electromagnet 23 is started, and the magnetic field generated by the electromagnet 23 is used to apply a longitudinal magnetic attraction to the horizontally rotating magnetic needle, so that the horizontally rotating magnetic needle flow can produce longitudinal fluctuations. At this time, the magnetic needle flowing in the polishing barrel 2 has multiple flow directions, which can rub the parts in multiple directions, thereby improving the polishing efficiency.

[0037] Combination Figure 3 and Figure 4 As shown, a flip motor 5 is provided on one side of the polishing barrel 2, and the output end of the flip motor 5 is connected to the side wall of the polishing barrel 2, and the flip motor 5 can drive both ends of the polishing barrel 2 to flip; In this way, when the polishing barrel 2 rotates to the discharge port 101 and before the bottom cover 21 is opened, the polishing barrel 2 is first driven by the flip motor 5 to flip the two ends of the polishing barrel 2. At this time, the material at the bottom of the polishing barrel 2 will fall on the top cover 22. Since the top cover 22 is provided with an electromagnet 23, the magnetic needle inside the polishing barrel 2 is adsorbed on the top cover 22 by the magnetic field of the electromagnet 23. Then the polishing barrel 2 is flipped again, and the top cover 22 is placed above the polishing barrel 2 again, and the bottom cover 21 is placed below the polishing barrel 2. At this time, the abrasive and non-magnetic parts fall on the bottom cover 21, and then the bottom cover 21 is opened, and the non-magnetic parts and abrasive are discharged. After the discharge, the bottom cover 21 is closed. After the bottom cover 21 is closed, the power supply of the electromagnet 23 is cut off. At this time, the magnetic needle falls into the polishing barrel 2 again. Therefore, when discharging, the electromagnet 23 on the top cover 22 can be used to separate the magnetic needle separately and keep it in the polishing barrel 2. The magnetic needle will not be discharged together with the abrasive and parts. The operator does not need to separate the parts and the magnetic needle, and there is no need to add the magnetic needle to the polishing barrel 2 again.

[0038] Furthermore, a plurality of drainage holes 221 are provided on the top cover 22. When the polishing barrel 2 is flipped, the abrasive in the polishing barrel 2 can be discharged from the drainage holes 221, thereby preventing the flow of abrasive from exerting an impact force on the magnetic needle and causing the magnetic needle to fall off when the polishing barrel 2 is flipped, thereby improving the stability of the electromagnet 23 in adsorbing the magnetic needle.

[0039] In this way, when the polishing barrel 2 rotates to the discharge port 101, the polishing barrel 2 is first driven by the flip motor 5 to flip the two ends of the polishing barrel 2. At this time, the abrasive can be discharged through the leaking hole 221, and the magnetic needle is adsorbed on the top cover 22 by the electromagnet 23. Then the polishing barrel 2 is flipped again, the top cover 22 is placed above the polishing barrel 2 again, and the bottom cover 21 is placed below the polishing barrel 2. The bottom cover 21 is opened, and the non-magnetic parts are discharged. After the parts are discharged, the bottom cover 21 is closed. After the bottom cover 21 is closed, the power supply of the electromagnet 23 is cut off. At this time, the magnetic needle falls into the polishing barrel 2 again. When discharging, the magnetic needle will not be discharged together with the abrasive and parts. The operator does not need to separate the parts and the magnetic needle, and there is no need to re-add the magnetic needle to the polishing barrel 2.

[0040] Furthermore, a filter screen 24 for filtering is provided in the water leakage hole 221 , so that the abrasive can be discharged through the filter screen 24 , while the magnetic needle and the workpiece are blocked by the filter screen 24 , thereby preventing the magnetic needle from being discharged from the water leakage hole 221 .

[0041] Combination Figure 1 and Figure 2 As shown, a turntable 6 is provided at the center of the machine 1, and a driving motor 7 for driving the turntable 6 to rotate is provided under the table top of the machine 1. Connecting frames 4 corresponding to the number of polishing barrels 2 are fixed on the turntable 6, and a flip motor 5 is fixed on the connecting frame 4.

[0042] The turntable 6 is driven to rotate by the driving motor 7 , and the turntable 6 drives the connecting frame 4 to rotate synchronously. Since the polishing barrel 2 is connected to the flip motor 5 on the connecting frame 4 , the connecting frame 4 drives the polishing barrel 2 to rotate through the flip motor 5 .

[0043] The working principle of the present invention is as follows: the driving motor 7 drives the turntable 6 to rotate, and the turntable 6 drives the connecting frame 4 to rotate synchronously. Since the polishing barrel 2 is connected to the flip motor 5 on the connecting frame 4, the connecting frame 4 drives the polishing barrel 2 to rotate through the flip motor 5, and the permanent magnetic disc 11 is driven to rotate through the magnetic disk motor 12, so that a horizontally rotating magnetic field is formed above the machine table 1, and the top cover 22 is opened by using the flip cover mechanism 3 at the corresponding position, and the parts to be polished, the magnetic needle and the abrasive are added into the polishing barrel 2, and then the top cover 22 is closed, and the polishing barrel 2 moves along the distribution path of the permanent magnetic disc 11, and the polishing barrel 2 corresponds to the permanent magnetic disc 11 one by one. The rotating permanent magnetic disc 11 can drive the magnetic needle in the polishing barrel 2 to rotate, and the friction between the magnetic needle and the parts is used to polish the surface of the parts; During the polishing process, the electromagnet 23 is started, and the magnetic field generated by the electromagnet 23 is used to apply a longitudinal magnetic attraction to the horizontally rotating magnetic needle, so that the horizontally rotating magnetic needle flow can produce longitudinal fluctuations. At this time, the magnetic needle flowing in the polishing barrel 2 has multiple flow directions, which can rub the parts in multiple directions, thereby improving the polishing efficiency; When the polishing barrel 2 rotates one circle and moves to the discharge port 101, the polishing barrel 2 is first driven by the flip motor 5 to flip the two ends of the polishing barrel 2. At this time, the abrasive can be discharged through the leaking hole 221, and the magnetic needle is adsorbed on the top cover 22 by the electromagnet 23. Then the polishing barrel 2 is flipped again, the top cover 22 is placed above the polishing barrel 2 again, and the bottom cover 21 is placed below the polishing barrel 2. The bottom cover 21 is opened, and the non-magnetic parts are discharged. After the parts are discharged, the bottom cover 21 is closed. After the bottom cover 21 is closed, the power supply of the electromagnet 23 is cut off. At this time, the magnetic needle falls into the polishing barrel 2 again. When discharging, the magnetic needle will not be discharged together with the abrasive and the parts. The operator does not need to separate the parts and the magnetic needle, and there is no need to add the magnetic needle to the polishing barrel 2 again. Then open the top cover 22, add the parts to be polished and the abrasive into the polishing barrel 2, and repeat the above steps for multiple polishing barrels 2, so that the workpiece can be polished continuously, and used in conjunction with the automatic loader to realize automatic loading, polishing and discharging of parts.

[0044] In summary of the above embodiments: by arranging an openable and closable top cover 22 above the polishing barrel 2, and arranging an electromagnet 23 on the top cover 22, during the polishing process, the electromagnet 23 is started, and the magnetic field generated by the electromagnet 23 is used to apply a longitudinal magnetic attraction to the horizontally rotating magnetic needle, so that the horizontally rotating magnetic needle flow can generate longitudinal fluctuations. At this time, the magnetic needle flowing in the polishing barrel 2 has multiple flow directions, and can rub the parts in multiple directions, thereby improving the polishing efficiency; By setting the flip motor 5, when the polishing barrel 2 is discharged, the flip motor 5 is used to drive the two ends of the polishing barrel 2 to flip, and the magnetic needle can be adsorbed on the top cover 22 by the electromagnet 23, and then the polishing barrel 2 is flipped again, and the bottom cover 21 is opened to discharge. At this time, the non-magnetic parts are discharged, and the magnetic needle is adsorbed on the top cover 22 by the electromagnet 23, completing the separation of the magnetic needle and the parts. When discharging, the magnetic needle will not be discharged together with the abrasive and the parts. The operator does not need to separate the parts and the magnetic needle, and there is no need to re-add the magnetic needle to the polishing barrel 2.
