Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic polishing technology, and in particular to a magnetic polishing needle separation device. Background Technology
[0002] The working principle of magnetic polishing is to guide the magnetic needle in the container to impact the workpiece at high frequency in a mixed medium (containing water and polishing liquid) through a high-speed rotating magnetic field, so as to achieve the purpose of removing burrs, polishing, and cleaning. It is suitable for deburring and polishing workpieces such as non-magnetic metals such as gold, silver, copper, aluminum, zinc, iron, and stainless steel, as well as non-metallic workpieces such as hard plastics.
[0003] Magnetic polishing offers advantages such as uniform polishing, smooth workpiece surfaces, excellent visual effects, enhanced workpiece surface quality, and low operating costs. It can be used to process irregular workpieces, internal holes, dead corners, and small gaps in structures such as holes or tubes, without damaging the workpiece surface or affecting its precision. It is particularly suitable for workpieces with complex shapes, multiple holes and gaps, and precise dimensions, enabling comprehensive and uniform polishing. It is widely used in fields such as handicrafts, hardware, medical, aerospace, automotive manufacturing, precision instruments, and electronic communications.
[0004] A magnetic polishing machine utilizing magnetic polishing technology comprises a housing and a turntable housed within the housing. A polishing barrel is mounted above the housing via a frame. Several electromagnets are spaced apart on the turntable, some of which have north (N) poles when energized, while the others have south (P) poles. Typically, adjacent electromagnets have different poles. A mixture of water and polishing fluid, a suitable amount of workpiece, and a suitable amount of unipolar magnetic needles are added to the polishing barrel. All electromagnets are energized, causing the turntable to rotate, alternating between forward and reverse directions. During rotation, the magnetic needles within the polishing barrel alternately jump under magnetic induction, continuously impacting the workpiece. Furthermore, the jumping needles, driven by the electromagnets, also move the mixed medium. Through the high-frequency impact of the magnetic needles and the rotation of the mixed medium, the workpiece is deburred and polished.
[0005] After the deburring and polishing operation is completed, the polishing bucket is tilted and emptied, and all the material inside is poured into a container. Then, the workpieces are manually sorted to separate them from the magnetic needles. Manual sorting has disadvantages such as low work efficiency, high labor intensity, and high labor costs. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a magnetic polishing needle separation device that can automatically separate the workpiece from the magnetic needle. Using this device can greatly improve production efficiency and reduce labor intensity and labor costs.
[0007] To address the problems of low work efficiency, high labor intensity, and high labor cost in current methods of separating workpieces from magnetic needles in polishing barrels, this solution designs a swing frame structure that automatically separates magnetic needles from workpieces through a swing screening method, greatly improving work efficiency and reducing labor intensity and labor costs.
[0008] The technical solution adopted by this utility model is: the magnetic polishing needle separation device includes: a filter box and a filter basket; The filter basket has a filter hole group that allows the magnetic needle and fluid medium inside the basket to leak out of the filter basket while the workpiece inside the basket remains inside the filter basket; the filter hole group is composed of several filter holes. An opening is provided at the top of the filter box, and a swinging device is provided inside the filter box. The filter basket can be placed on the swinging device through the opening, and the magnetic needles in the filter basket will be spun out and fall into the filter box by the swinging device.

[0009] Furthermore, in the aforementioned magnetic polishing needle separation device, the structure of the oscillating device includes: an oscillating frame capable of supporting the filter basket; The swing frame has a support shaft at each of its front and rear ends, and the two support shafts are coaxial. The two support shafts are supported in the filter box by their respective first bearing groups, thereby suspending the swing frame in the filter box. Each support shaft is driven by a swing drive mechanism; under the drive of the swing drive mechanism, the swing frame swings back and forth.
[0010] Furthermore, in the aforementioned magnetic polishing needle separation device, the structure of the swing frame includes: a front swing plate and a rear swing plate; the bottom of the front swing plate and the bottom of the rear swing plate are connected by at least two bottom support beams; the left part of the front swing plate and the left part of the rear swing plate are connected by at least one left support beam; the right part of the front swing plate and the right part of the rear swing plate are connected by at least one right support beam. The filter basket has at least two left-side resting parts on the left side and at least two right-side resting parts on the right side. When the filter basket is placed on the swing frame, the bottom of the filter basket rests on each bottom support beam, each left-side resting part rests on the uppermost left support beam, and each right-side resting part rests on the uppermost right support beam.
[0011] Furthermore, in the aforementioned magnetic polishing needle separation device, both the front swing plate and the rear swing plate are planar frame plate structures with several hollowed-out areas.
[0012] Furthermore, in the aforementioned magnetic polishing needle separation device, the structure of the swing drive mechanism is as follows: a mounting base is fixedly installed on the outer wall of the filter box located at any one of the support shafts, and a first drive motor is fixed on the mounting base; one end of the crank is fixed to the motor shaft of the first drive motor, the other end of the crank is hinged to one end of the connecting rod, the other end of the connecting rod is hinged to one end of the rocker arm, and the other end of the rocker arm is fixedly connected to the corresponding support shaft, and the crank, connecting rod, and rocker arm constitute a crank-rocker mechanism.
[0013] Furthermore, in the aforementioned magnetic polishing needle separation device, the bottom surface of the filter box is an inverted triangle shape consisting of a left inclined bottom surface and a right inclined bottom surface, with a lower center and higher sides.
[0014] Furthermore, in the aforementioned magnetic polishing needle separation device, the filter basket structure includes: a filter basket frame; the empty areas on the sides and bottom of the filter basket frame are closed by a filter screen plate, and the filter hole group is composed of filter holes on the filter screen plate. In this case, only the filter holes on the entire filter basket frame allow the magnetic needle and fluid medium to pass through. The size of each filter hole is smaller than the size of the workpiece, therefore the workpiece can only remain inside the filter basket.
[0015] Furthermore, in the aforementioned magnetic polishing needle separation device, the structure of the filter basket frame includes: a front support plate and a rear support plate; the front support plate and the rear support plate are connected by several connecting beams to form a three-dimensional frame structure; the filter screen is encapsulated on the bottom, left and right sides of the three-dimensional frame structure.
[0016] Furthermore, in the aforementioned magnetic polishing needle separation device, a magnetic polishing machine is also installed outside the filter box; two tilting arms are fixedly installed on the polishing barrel of the magnetic polishing machine, and the two tilting arms are fixedly connected to a tilting rod. The tilting rod is supported on the frame by a second bearing assembly, and a second drive motor is fixedly installed on the frame. The motor shaft of the second drive motor is fixedly connected to the tilting rod; under the drive of the second drive motor, the polishing barrel can be tilted and poured into the filter basket inside the filter box; The bottom surface of the polishing barrel has several spaced protrusions, and the concave surfaces between each protrusion can allow at least one magnetic needle to pass through.
[0017] Furthermore, in the aforementioned magnetic polishing needle separation device, the protrusion is hemispherical in shape.
[0018] Furthermore, in the aforementioned magnetic polishing needle separation device, the protrusions on the bottom surface of the polishing barrel are composed of a central protrusion and several peripheral protrusions of the same shape and size. The hemispherical diameter of the central protrusion is larger than that of the peripheral protrusions, and the peripheral protrusions are evenly distributed on the bottom surface of the polishing barrel except for the central protrusion.
[0019] Furthermore, in the aforementioned magnetic polishing needle separation device, an extended discharge end is provided at the top of the polishing barrel. After the polishing barrel is tilted over, all the material inside the polishing barrel is discharged through the extended discharge end, and the filter basket in the filter box can receive the material discharged from the extended discharge end.
[0020] The beneficial effects of this utility model are: ① The magnetic polishing needle separation equipment described in this solution can automatically separate the workpiece from the magnetic needle, with good separation effect and high degree of automation, which greatly improves production efficiency and reduces labor intensity and labor costs; ② The overall structure of the swing frame and filter basket described in this solution is lightweight, and the overall center of gravity is in the middle position, which is well balanced. During the swinging of the screen needle, the workpiece in the filter basket will not be thrown out of the filter basket, and the filter basket will not tip over; ③ The concave surfaces between the protrusions on the bottom surface of the polishing barrel can allow the magnetic needles to enter. The entering magnetic needles can hit the bottom surface of the workpiece, giving the workpiece a chance to flip over. The flipped workpiece can also be hit by the magnetic needles. Therefore, the surface of the workpiece attached to the bottom of the polishing barrel can also be hit by the magnetic needles for deburring and polishing, which further improves the deburring and polishing effect of the workpiece, makes the deburring and polishing of the workpiece surface more uniform, and improves the surface quality of the workpiece.

Therefore, they should not be construed as limitations on this utility model. Example 1
[0041] like Figure 1 As shown, the magnetic polishing needle separation device in this embodiment includes: a filter box 1 and a filter basket 2.
[0042] The filter basket 2 has a filter hole group. The function of the filter hole group is that when the material containing the workpiece, magnetic needle and mixed medium is poured into the filter basket 2, the magnetic needle in the basket can be leaked out of the filter basket 2 through the filter hole group, while the workpiece in the basket is left in the filter basket 2, and the mixed medium can also be leaked out of the filter basket 2 through the filter hole group.
[0043] An opening is provided at the top of the filter box 1, and a swinging device is provided inside the filter box 1. The filter basket 2 can be placed on the swinging device through the opening and the magnetic needles in the filter basket 2 can be spun out by the swinging device. The spun magnetic needles fall into the filter box 1.
[0044] like Figure 4 , Figure 5 and Figure 6 As shown, the structure of the swing device described in this embodiment includes a swing frame 3 that can support the filter basket 2.
[0045] The swing frame 3 has a support shaft at each end, defined as a front support shaft 33 and a rear support shaft 34, which are coaxial. The two support shafts are supported in the filter box 1 by their respective first bearing assemblies, thereby suspending the swing frame 3 in the filter box 1.
[0046] Each support shaft is driven by the swing drive mechanism 4; under the drive of the swing drive mechanism 4, the swing frame 3 swings back and forth left and right without hitting the filter box 1.
[0047] like Figure 4 , Figure 7 and Figure 8 As shown, in this embodiment, the structure of the swing drive mechanism 4 is as follows: a mounting base 41 is fixedly installed on the outer wall of the filter box 1 located at any one of the support shafts, and the first drive motor is fixed on the mounting base 41; one end of the crank 42 is fixed to the motor shaft 45 of the first drive motor, the other end of the crank 42 is hinged to one end of the connecting rod 43, the other end of the connecting rod 43 is hinged to one end of the rocker arm 44, and the other end of the rocker arm 44 is fixedly connected to the corresponding support shaft. The crank 42, the connecting rod 43, and the rocker arm 44 constitute a crank-rocker mechanism. The crank-rocker mechanism is a type of conventional four-bar linkage, so the working principle of the crank-rocker mechanism will not be elaborated here. When the first drive motor drives the crank 42 to rotate a full circle, the rocker arm 44 swings back and forth, thus achieving the purpose of swinging the swing frame 3 back and forth. During the back and forth swinging of the swing frame 3, it is equivalent to sieving the filter basket 2, thereby sieving the magnetic needles out of the filter basket 2.
[0048] The magnetic polishing needle separation equipment with the above structure can automatically separate the workpiece from the magnetic needle, with good separation effect and high degree of automation, which greatly improves production efficiency and reduces labor intensity and labor costs.
[0049] A better option is: such as Figure 5 As shown, the bottom surface of the filter box 1 is designed as an inverted triangle shape with a low center and high sides, formed by the left inclined bottom surface 11 and the right inclined bottom surface 12. This makes it easier for the magnetic needles to concentrate in the middle of the bottom surface of the filter box 1, which facilitates the subsequent collection of the magnetic needles. For example, when collecting the magnetic needles in the filter box 1 by attracting the magnetic needles with a magnet, the magnet only needs to be inserted into the middle of the bottom surface of the filter box 1.
[0050] In addition, in order to facilitate the discharge of the mixed medium (which is a fluid containing clean water, polishing liquid, and impurities generated during the deburring and polishing process) in the filter box 1, at least one drain pipe 13 can be provided on the left inclined bottom surface 11 or / and the right inclined bottom surface 12. Each drain pipe 13 is normally closed and is only opened when the mixed medium needs to be discharged. Example 2
[0051] like Figure 1 As shown, the magnetic polishing needle separation device in this embodiment includes: a filter box 1 and a filter basket 2.
[0052] The filter basket 2 has a filter hole group. The function of the filter hole group is that when the material containing the workpiece, magnetic needle and mixed medium is poured into the filter basket 2, the magnetic needle in the basket can be leaked out of the filter basket 2 through the filter hole group, while the workpiece in the basket is left in the filter basket 2, and the mixed medium can also be leaked out of the filter basket 2 through the filter hole group.
[0053] An opening is provided at the top of the filter box 1, and a swinging device is provided inside the filter box 1. The filter basket 2 can be placed on the swinging device through the opening and the magnetic needles in the filter basket 2 can be spun out by the swinging device. The spun magnetic needles fall into the filter box 1.
[0054] like Figure 4 , Figure 5 and Figure 6 As shown, the structure of the swing device described in this embodiment includes a swing frame 3 that can support the filter basket 2.
[0055] The swing frame 3 has a support shaft at each end, defined as a front support shaft 33 and a rear support shaft 34, which are coaxial. The two support shafts are supported in the filter box 1 by their respective first bearing assemblies, thereby suspending the swing frame 3 in the filter box 1.
[0056] Each support shaft is driven by the swing drive mechanism 4; under the drive of the swing drive mechanism 4, the swing frame 3 swings back and forth left and right without hitting the filter box 1.
[0057] like Figure 6 As shown, the structure of the swing frame 3 in this embodiment includes: a front swing plate 31 and a rear swing plate 32; the bottom of the front swing plate 31 and the bottom of the rear swing plate 32 are connected by at least two bottom support beams 35; the left part of the front swing plate 31 and the left part of the rear swing plate 32 are connected by at least one left support beam 36; the right part of the front swing plate 31 and the right part of the rear swing plate 32 are connected by at least one right support beam 37.
[0058] A more preferred embodiment is that there are preferably two bottom support beams 35. There is preferably one left support beam 36, typically located to the upper left of the front swing plate 31 and the rear swing plate 32. There is preferably one right support beam 37, typically located to the upper right of the front swing plate 31 and the rear swing plate 32.
[0059] A more preferred embodiment is that the left support beam 36, the right support beam 37, and the two bottom support beams 35 are symmetrically distributed on the vertical center plane of the swing frame 3 that is perpendicular to the front swing plate 31.
[0060] A more preferred embodiment is that both the front swing plate 31 and the rear swing plate 32 are planar frame plate structures with several hollowed-out areas.
[0061] A more preferred embodiment is that the front swing plate 31 is symmetrically distributed with respect to the center line, and the front swing plate 31 and the rear swing plate 32 have the same shape, structure and size.
[0062] The swing frame 3 described above has a lightweight overall structure and a central center of gravity, which is well-balanced and conducive to the stability of left and right swinging. During the swinging of the screen needle, the workpiece in the filter basket 2 will not be thrown out of the filter basket 2.
[0063] like Figure 2 and Figure 3 As shown, in this embodiment, the filter basket 2 has at least two left resting parts 23 on the left side and at least two right resting parts 24 on the right side; when the filter basket 2 is placed on the swing frame 3, the bottom of the filter basket 2 rests on each bottom support beam 35, each left resting part 23 rests on the uppermost left support beam 36, and each right resting part 24 rests on the uppermost right support beam 37.
[0064] The left and right shelf sections 23 and 24 are identical in structure, shape and size, and can be hook-shaped, shelf-like, etc.
[0065] like Figure 1 , Figure 2 and Figure 3 As shown, the structure of the filter basket 2 in this embodiment includes: a filter basket frame; the empty areas on the sides and bottom of the filter basket frame are closed by a filter screen plate 26, and the filter hole group is composed of each filter hole on the filter screen plate 26.
[0066] In this embodiment, the filter basket frame structure includes a front support plate 21 and a rear support plate 22. The front support plate 21 and the rear support plate 22 are connected by several connecting beams 25 to form a three-dimensional frame structure. A filter screen plate 26 is encapsulated on the bottom, left, and right sides of the three-dimensional frame structure. At this time, only the filter holes on the filter screen plate 26 are empty areas on the entire filter basket 2. Under the swing of the swing device, the needle can only leak downward through the filter holes and out of the filter basket 2, so the workpiece will still remain in the filter basket 2, thus achieving the purpose of needle separation.
[0067] A more preferred embodiment is that the filter basket 2 is symmetrically distributed from left to right relative to the vertical center plane of the filter basket 2 that is perpendicular to the front support plate 21, and is also symmetrically distributed from front to back relative to the vertical center plane of the filter basket 2 that is parallel to the front support plate 21.
[0068] A more preferred embodiment is that there are two left-side resting portions 23, located on the left end of the front support plate 21 and the left end of the rear support plate 22. There are also two right-side resting portions 24, located on the right end of the front support plate 21 and the right end of the rear support plate 22.
[0069] The filter basket 2 described above has a lightweight overall structure and a central center of gravity, resulting in good balance. When used in conjunction with the swing device, it exhibits excellent stability when swinging left and right, preventing tipping over. Example 3
[0070] like Figure 1 As shown, the magnetic polishing needle separation device in this embodiment includes: a filter box 1 and a filter basket 2.
[0071] The filter basket 2 has a filter hole group. The function of the filter hole group is that when the material containing the workpiece, magnetic needle and mixed medium is poured into the filter basket 2, the magnetic needle in the basket can be leaked out of the filter basket 2 through the filter hole group, while the workpiece in the basket is left in the filter basket 2, and the mixed medium can also be leaked out of the filter basket 2 through the filter hole group.
[0072] An opening is provided at the top of the filter box 1, and a swinging device is provided inside the filter box 1. The filter basket 2 can be placed on the swinging device through the opening and the magnetic needles in the filter basket 2 can be spun out by the swinging device. The spun magnetic needles fall into the filter box 1.
[0073] like Figure 4 , Figure 5 and Figure 6 As shown, the structure of the swing device described in this embodiment includes a swing frame 3 that can support the filter basket 2.
[0074] The swing frame 3 has a support shaft at each end, defined as a front support shaft 33 and a rear support shaft 34, which are coaxial. The two support shafts are supported in the filter box 1 by their respective first bearing assemblies, thereby suspending the swing frame 3 in the filter box 1.
[0075] Each support shaft is driven by the swing drive mechanism 4; under the drive of the swing drive mechanism 4, the swing frame 3 swings back and forth left and right without hitting the filter box 1.
[0076] like Figure 9 As shown, a magnetic polishing machine 5 is also installed outside the filter box 1. In this embodiment, the magnetic polishing machine 5 is an existing mature product, comprising: a housing 51 and a turntable disposed within the housing 51. A polishing barrel 6 is mounted above the housing 5 via a frame. Several electromagnets are spaced apart on the turntable, some of which have N poles when energized, while the others have P poles. Typically, adjacent electromagnets have different poles. A mixture of water and polishing fluid, a suitable amount of workpiece, and a suitable amount of magnetic needles (unipolar magnetic needles) are added to the polishing barrel 6. All electromagnets are energized, and the turntable rotates, alternating between forward and reverse rotation. During the rotation of the turntable, the magnetic needles inside the polishing barrel 6 alternately jump under the magnetic effect, continuously impacting the workpiece. Furthermore, the jumping magnetic needles driven by the electromagnets also drive the movement of the mixture. The high-frequency impact of the magnetic needles and the rotation of the mixture perform deburring and polishing operations on the workpiece.
[0077] However, due to the gravity of the workpiece itself, and the flat bottom of the polishing barrel 6, it is difficult to flip the workpiece that is attached to the bottom of the polishing barrel 6. As a result, the surface of the workpiece that is attached to the bottom of the polishing barrel 6 cannot contact the magnetic needle for deburring and polishing.
[0078] This embodiment addresses the aforementioned problems by designing the polishing bucket 6 as follows: Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, a number of spaced protrusions are provided on the bottom surface of the polishing barrel 6, and the concave surfaces between each protrusion are large enough for at least one magnetic needle to pass through. The diameter of a single magnetic needle is typically 0.2-0.5 mm.
[0079] The protrusion can be formed by stamping. The shape of the protrusion can be hemispherical or other shapes, wherein the protrusion is preferably hemispherical.
[0080] A more preferred embodiment is that the protrusions on the bottom surface of the polishing barrel 6 are composed of a central protrusion 63 and several peripheral protrusions 64 of the same shape and size. The hemispherical diameter of the central protrusion 63 is larger than that of the peripheral protrusions 64, and the peripheral protrusions 64 are evenly distributed on the bottom surface of the polishing barrel 6 except for the central protrusion 63.
[0081] At this time, the concave surfaces between the protrusions on the bottom surface of the polishing barrel 6 allow the magnetic needles to enter. The entering magnetic needles can then strike the bottom surface of the workpiece, giving the workpiece a chance to flip over. The flipped workpiece can also be struck by the magnetic needles, so the surface of the workpiece that is attached to the bottom of the polishing barrel 6 can also be struck by the magnetic needles to perform deburring and polishing operations, further improving the deburring and polishing effect of the workpiece.
[0082] Furthermore, the polishing bucket 6 is mounted on top of the housing 5 via a frame as follows: Figure 9 and Figure 10 As shown, two tilting arms 61 are fixedly mounted on the polishing barrel 6, and the two tilting arms 61 are fixedly connected to a tilting rod 71. The tilting rod 71 is supported on the frame by a second bearing assembly, and the frame can be a frame structure. A second drive motor 72 is fixedly mounted on the frame, and the motor shaft of the second drive motor 72 is fixedly connected to the tilting rod 71. Driven by the second drive motor 72, the polishing barrel 6 can tilt and pour out all the material in the polishing barrel 6 into the filter basket 2 in the filter box 1.
[0083] A better option is: such as Figure 9 and Figure 10 As shown, an extended discharge end 62 is provided at the top of the polishing barrel 6. After the polishing barrel 6 is tilted, all the material inside the polishing barrel 6 is discharged through the extended discharge end 62, and the filter basket 2 in the filter box 1 can receive the material discharged from the extended discharge end 62. The extended discharge end 62 facilitates the transition of material from the polishing barrel 6 to the filter basket 2 in the filter box 1, and can effectively prevent the phenomenon of material spilling out of the filter basket 2 during the material transition process.
[0084] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
