Description

Technical Field

[0001] This utility model relates to the field of magnetic polishing technology, and in particular to a magnetic polishing needle recycling production system. 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

[0016] Furthermore, in the aforementioned magnetic polishing needle recycling production system, the structure of the oscillating device includes: an oscillating frame capable of supporting the filter basket; A support shaft is provided at the upper center of the left end and the upper center of the right end of the swing frame.

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.

Therefore, they should not be construed as limitations on this utility model. Example 1

[0044] like Figure 1 , Figure 2 and Figure 4 As shown in the figure, the magnetic polishing needle recycling production system described in this embodiment includes at least one magnetic polishing machine 1. When there are two or more magnetic polishing machines 1, they are arranged sequentially from front to back. The attached figure illustrates an example with four magnetic polishing machines 1. In actual production workshops, the number of magnetic polishing machines 1 is arranged according to the needs of each factory, and no limit is placed on the number of magnetic polishing machines 1 here.

[0045] The magnetic polishing needle recycling production system described in this embodiment also includes: several filter baskets 2, such as... Figure 5 As shown, the filter basket 2 has a group of filter holes through which magnetic needles and the mixed medium can pass, but the workpiece cannot. The materials fed into the polishing barrel 8 of the magnetic polishing machine 1 include: an appropriate amount of workpiece, an appropriate amount of magnetic needle, and an appropriate amount of mixed medium, which contains water and polishing liquid. After the magnetic polishing machine 1 performs deburring and polishing operations, when the materials in the polishing barrel 8 of the polishing machine 1 are poured into the filter basket 2, the magnetic needle can pass through each filter hole in the filter hole group and fall downwards, and the mixed medium can also leak downwards through each filter hole in the filter hole group, while the workpiece remains in the filter basket 2.

[0046] Since there are a certain number of workpieces and magnetic needles, they are mixed together after deburring and polishing. Therefore, when they are poured directly into the filter basket 2, only the bottom part of the magnetic needles can fall down through the filter holes, while some magnetic needles are trapped between the workpieces. Therefore, in order to completely separate the magnetic needles from the workpieces, this embodiment is equipped with a material needle separation device 3 at each magnetic polishing machine 1.

[0047] like Figure 5 As shown, the structure of the material needle separation device 3 described in this embodiment includes: a filter box 31, an open opening at the top of the filter box 31, and a swinging device inside the filter box 31; a single filter basket 2 can be placed on the swinging device through the open opening to receive the material poured out from the polishing barrel 8 of the corresponding magnetic polishing machine 1, and the magnetic needles in the filter basket 2 are swung out and dropped into the filter box 31 by the swinging device.

[0048] like Figure 1 and Figure 4 As shown, the magnetic polishing needle recycling production system described in this embodiment also includes a frame 4, which can be a three-dimensional frame structure that includes all components to facilitate the subsequent installation of each component.

[0049] The gripping mechanism 5 is mounted on the frame 4 via a first combined sliding device assembly. The gripping mechanism 5 is used to grip and release the filter basket 2, and the first combined sliding device assembly allows the gripping mechanism 5 to move in four directions: forward, backward, up, and down. The gripping mechanism 5, in cooperation with the first combined sliding device assembly, can grip the filter basket 2 at a designated position in the preceding stage and place it into the corresponding filter box 31. The gripping mechanism 5, also in cooperation with the first combined sliding device assembly, can grip, lift, and transport the filter basket 2 from each filter box 31 to a designated position in the subsequent stage.

[0050] To facilitate automation, a front-end chain conveyor can be installed at a designated position in the upstream process, transporting empty filter baskets 2 to that position. Similarly, a rear-end chain conveyor can be installed at a designated position in the downstream process, transporting filter baskets 2 containing only workpieces to the next workstation via the rear-end chain conveyor. Since chain conveyors are a mature product, this solution utilizes a chain conveyor rather than modifying or optimizing its structure. Therefore, for simplicity, the attached diagram only schematically shows the two sets of chains 10 of the chain conveyor, with the filter baskets 2 resting on these chains 10.

[0051] When there is only one magnetic polishing machine 1, there is only one needle separator 3. The designated position of the front channel is located in front of the needle separator 3, and the designated position of the rear channel is located behind the needle separator 3.

[0052] When there are two or more magnetic polishing machines 1, the designated position of the front channel is located in front of the material needle separation device at the very front, and the designated position of the rear channel is located behind the material needle separation device at the very back.

[0053] The designated positions in the upstream process, each material needle separator 3, and the designated positions in the downstream process are all on the same straight line. Regarding this layout, as follows... Figure 1 , Figure 2 and Figure 4 As shown, the first combined sliding device group in this embodiment includes: a first linear slide module 41 and a second linear slide module 42.

[0054] The slide rails in the first linear slide module 41 are horizontally placed and fixed on the frame 1, and the slide rails in the second linear slide module 42 are vertically placed and fixed on the slider in the first linear slide module 41. The second linear slide module 42 can move forward or backward through the first linear slide module 41. The gripping mechanism 5 is fixed on the slider in the second linear slide module 42, and the gripping mechanism 5 can move upward or downward through the second linear slide module 42.

[0055] Electromagnet 6 is mounted on the frame 4 via a second combined sliding device assembly. Electromagnet 6 is connected to a circuit, and the circuit for switching the power on and off of electromagnet 6 is a mature product, so it will not be described in detail here. When electromagnet 6 is energized, it can attract magnetic needles; when electromagnet 6 is de-energized, the magnetic needles attracted to it fall off. The second combined sliding device assembly is used to move electromagnet 6 in six directions: forward, backward, left, right, up, and down. Electromagnet 6 can be moved via the second combined sliding device assembly to the filter box 31 of each needle separation device 3 and energized to generate a magnetic field that attracts the magnetic needles from the corresponding filter box 31. Electromagnet 6 can also be moved via the second combined sliding device assembly to the polishing barrel 8 of each magnetic polishing machine 1 and de-energized to cause the magnetic needles attracted to it to fall into the corresponding polishing barrel 8.

[0056] The material needle separation device 3 is positioned to the left of the corresponding magnetic polishing machine 1. The layout of the magnetic polishing machine 1 and the material needle separation device 3 is as follows: Figure 1 , Figure 2 and Figure 4 As shown, the second combined sliding device group in this embodiment includes: a third linear slide module 43, a fourth linear slide module 44, a fifth linear slide module 45, and a sixth linear slide module 46.

[0057] The slide rails in the third linear slide module 43 and the slide rails in the fourth linear slide module 44 are both placed and fixed on the frame 4 in a front-to-back horizontal direction, and the slide rails in the third linear slide module 43 and the slide rails in the fourth linear slide module 44 are parallel to each other. The slide rails in the fifth linear slide module 45 are arranged horizontally from left to right, and the left part of the slide rails in the fifth linear slide module 45 is fixed to the slider in the third linear slide module 43, while the right part of the slide rails in the fifth linear slide module 445 is fixed to the slider in the fourth linear slide module 44. This allows the third linear slide module 43 and the fourth linear slide module 44 to drive their respective sliders to move synchronously and in the same direction. At this time, the fifth linear slide module 45 can move forward or backward.

[0058] The slide rail in the sixth linear slide module 46 is vertically positioned and fixed to the slider in the fifth linear slide module 45, and the sixth linear slide module 46 can move left or right via the fifth linear slide module 45. The electromagnet 6 is fixed to the slider in the sixth linear slide module 46 via a fixing rod 61, and the electromagnet 6 can move up or down via the sixth linear slide module 46.

[0059] To facilitate better extraction of the magnetic needle from the filter box 31 by the electromagnet 6, such as Figure 9 As shown, a more preferred embodiment is that the bottom surface of the filter box 31 is an inverted triangle shape, with a lower center and higher front and rear sides, formed by a front inclined bottom surface 311 and a rear inclined bottom surface 312. This arrangement ensures that the magnetic needles falling into the filter box 31 will converge towards the center of the bottom surface of the filter box 31 along the front inclined bottom surface 311 and the rear inclined bottom surface 312, which facilitates the electromagnet 6 in attracting the magnetic needles and does not interfere with the swinging device swinging the filter basket 2.

[0060] 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 31, at least one drain pipe 313 can be provided on the front inclined bottom surface 311 or / and the rear inclined bottom surface 312. Each drain pipe 313 is normally closed and is only opened when the mixed medium needs to be discharged.

[0061] The working process of the above-mentioned magnetic polishing needle recycling production system is as follows: First, add an appropriate amount of mixed medium, an appropriate amount of workpiece, and an appropriate amount of magnetic needles to the polishing barrel 8 of each magnetic polishing machine 1, and start each magnetic polishing machine 1 to perform deburring and polishing operations on the workpiece. The feeding method can be manual or automatic, such as using a feeding trolley or automatic feeding device; there are no restrictions here. Magnetic polishing machine 1 is a mature product, and its structure and working principle will not be described in detail here.

[0062] After any magnetic polishing machine 1 completes the deburring and polishing operation on the workpiece in the polishing barrel 8, the polishing barrel 8 on the magnetic polishing machine 1 is tilted and poured into the filter basket 2 in the corresponding material needle separation device 3, and the swing device is started to screen the needles.

[0063] After all the magnetic needles in the filter basket 2 are sieved out, the first linear slide module 41 is activated, driving the second linear slide module 42 to move horizontally until the gripping mechanism 5 on the second linear slide module 42 is above the filter box 31 corresponding to the polishing machine 1; then the second linear slide module 42 is activated, driving the gripping mechanism 5 to grip the filter basket 2 downwards, and after gripping the filter basket 2, the gripping mechanism 5 is moved upwards to a specified height via the second linear slide module 42; then the first linear slide module 41 is activated, driving the second linear slide module 42 to move horizontally until the gripping mechanism 5 on the second linear slide module 42 is above the specified position in the subsequent process; then the second linear slide module 42 is activated, driving the gripping mechanism 5 to move downwards until the filter basket 2 is placed on the two sets of chains 10 of the subsequent chain conveyor, and after the gripping mechanism 5 releases the filter basket 2, it moves upwards to a specified height via the second linear slide module 42, and finally returns to the initial position of the gripping mechanism 5 via the first linear slide module 41.

[0064] After all the magnetic needles in the filter basket 2 have been sifted out and the filter basket 2 has left the corresponding filter box 31, the third linear slide module 43 and the fourth linear slide module 44 are activated, driving the fifth linear slide module 45 to move above the filter box 31; then the fifth linear slide module 45 is activated, driving the electromagnet 6 to move above the filter box 31; then the sixth linear slide module 46 is activated, driving the electromagnet 6 to move downwards and extend into the filter box 31, energizing the electromagnet 6, at which point the electromagnet 6 will attract the magnetic needles in the filter box 31; then the sixth linear slide module 46 is activated, driving the electromagnet 6 to move upwards to the specified height. Then, the fifth linear slide module is activated, moving the electromagnet 6 to above the polishing barrel 8 corresponding to the filter box 31; then, the sixth linear slide module 46 is activated, moving the electromagnet 6 downwards into the polishing barrel 8, de-energizing the electromagnet 6, causing the magnetic needle attracted to the electromagnet 6 to fall into the polishing barrel 8, and the fallen magnetic needle can then participate in the deburring and polishing operation of the next batch of workpieces; then, the sixth linear slide module 46 is activated, moving the electromagnet 6 upwards to the specified height; then, through the actions of the fifth linear slide module 45, the third linear slide module 43, and the fourth linear slide module 44, the electromagnet 6 returns to its initial position.

[0065] The aforementioned magnetic polishing needle recycling production system can automatically separate the workpiece from the magnetic needle and reuse the separated magnetic needle. It has a high degree of automation, which greatly improves production efficiency and reduces labor intensity and labor costs. Example 2

[0066] This embodiment is designed based on the structure of the filter basket 2 described in Embodiment 1, such as... Figure 5 and Figure 7 As shown, the structure of the filter basket 2 in this embodiment includes: a filter basket frame; the structure of the filter basket frame includes: a left support plate 21 and a right support plate 22; the left support plate 21 and the right support plate 22 are connected by several connecting beams 25 to form a three-dimensional frame structure.

[0067] The filter plate 26 is encapsulated on the bottom, front and rear of the three-dimensional frame structure, and the left end of the filter plate 26 is connected to the left support plate 21, and the right end of the filter plate 26 is connected to the right support plate 22; the filter hole group is composed of the filter holes on the filter plate 26.

[0068] In this embodiment, the filter plate 26 can be a single filter plate or a combination of several filter plates. The filter plates can be joined together by fixing them to the connecting beams 25.

[0069] In this embodiment, a first support rod 27 is provided at the front of the filter basket 2, and a second support rod 28 is provided at the rear of the filter basket 2. The first support rod 27 and the second support rod 28 are at the same height and are parallel to each other, and are placed horizontally in the left and right direction. This arrangement is also to facilitate the gripping by the gripping mechanism 5 and to ensure the balance of the filter basket 2 during the transportation process of the gripping mechanism 5.

[0070] like Figure 3 , Figure 10 , Figure 12 , Figure 13 and Figure 14 As shown, the gripping mechanism 5 described in this embodiment includes a mounting base 56, on which a pair of gripping claws are provided, the pair of gripping claws being located on the left and right sides of the mounting base 5 respectively.

[0071] Each gripper has the following structure: a first gripper arm 51 and a second gripper arm 53 are respectively hinged to the mounting base 56; one end of a first connecting rod 52 is hinged to a central connecting rod 55, and the other end of the first connecting rod 52 is hinged to the upper end of the first gripper arm 51, the lower end of the first gripper arm 51 being a first hook 5011 capable of hooking the first support rod 27. One end of a second connecting rod 54 is hinged to the central connecting rod 55, and the other end of the second connecting rod 54 is hinged to the upper end of the second gripper arm 53, the lower end of the second gripper arm 53 being a second hook 5031 capable of hooking the second support rod 28. A fixing plate 57 is provided on the mounting base 56, and an oblong groove 571 is formed on the fixing plate 57, the central connecting rod 55 extending into the oblong groove 571. The fixing plate 57 can be a part of the mounting base 56, or it can be fixed to the mounting base 56 by means of threaded connection, welding, etc.

[0072] The first connecting rod 52 and the second connecting rod 54 are symmetrically distributed front to back with respect to the center of the middle connecting rod 55. The first gripper arm 51 and the second gripper arm 53 are symmetrically distributed front to back with respect to the center of the middle connecting rod 55. The first hook 5011 and the second hook 5031 are symmetrically distributed front to back with respect to the center of the middle connecting rod 55.

[0073] The mounting base 56 is provided with a gripping and releasing drive mechanism that drives the middle connecting rod 55 of a pair of gripping claws to move synchronously upward in the corresponding waist-shaped long groove 571 so that the first hook 5011 and the second hook 5013 move inward synchronously or move downward synchronously so that the first hook 5011 and the second hook 5013 open outward synchronously.

[0074] like Figure 12 As shown, the structure of the gripping and releasing drive mechanism in this embodiment is as follows: a cylinder or hydraulic cylinder 58 is fixedly mounted on the mounting base 56, with the piston rod of the cylinder or hydraulic cylinder 58 facing downwards. A bottom mounting bracket 59 is fixedly mounted on the piston rod of the cylinder or hydraulic cylinder 58, and a drive rod 50 arranged horizontally to the left and right is fixedly mounted on the bottom mounting bracket 59. Two central connecting rods 55 on the pair of gripping claws are located at the left and right ends of the drive rod 50. The two central connecting rods 55 can be fixed to the left and right ends of the drive rod 50 by means of threaded connection, welding, etc., or the two central connecting rods 55 can be integrally formed with the drive rod 50.

[0075] In order to enable the pair of gripping claws to synchronously and stably grip and release the filter basket 2, this embodiment adds a first connecting rod 510, a second connecting rod 511, a third connecting rod 512 and a fourth connecting rod 513 on the basis of the above structure.

[0076] The first gripper arm 51 is hinged to the mounting base 56 via a first hinge shaft 514. The two first hinge shafts 514 on the pair of grippers are located at the left and right ends of the first connecting rod 510. The two first hinge shafts 514 can be fixed to the left and right ends of the first connecting rod 510 by means of threaded connection, welding, etc., or the two first hinge shafts 514 can be integrally formed with the first connecting rod 510.

[0077] The second gripper arm 53 is hinged to the mounting base 56 via a second hinge shaft 515. The two second hinge shafts 515 on the pair of grippers are located at the left and right ends of the second connecting rod 511. The two second hinge shafts 515 can be fixed to the left and right ends of the second connecting rod 511 by means of threaded connection, welding, etc., or the two second hinge shafts 515 can be integrally formed with the second connecting rod 511.

[0078] The first connecting rod 52 and the first gripper arm 51 are hinged together by a third hinge shaft 516. The two third hinge shafts 516 on the pair of grippers are located at the left and right ends of the third connecting rod 512. The two third hinge shafts 516 can be fixed to the left and right ends of the third connecting rod 512 by means of threaded connection, welding, etc., or the two third hinge shafts 516 can be integrally formed with the third connecting rod 512.

[0079] The second connecting rod 54 and the second gripper arm 53 are hinged together by a fourth hinge shaft 517. The two fourth hinge shafts 517 on the pair of grippers are located at the left and right ends of the fourth connecting rod 513. The two fourth hinge shafts 517 can be fixed to the left and right ends of the fourth connecting rod 513 by means of threaded connection, welding, etc., or the two fourth hinge shafts 517 can be integrally formed with the fourth connecting rod 513.

[0080] The working process of the aforementioned grabbing mechanism 5 is as follows: When it is necessary to grasp the filter basket 2, the piston rod of the cylinder or hydraulic cylinder 58 extends downward, forcing the two central connecting rods 55 to move downward in the waist-shaped groove 571. This forces the first connecting rod 52 and the second connecting rod 54 to move inward around the central connecting rod 55. During the process of the first connecting rod 52 and the second connecting rod 54 moving inward around the central connecting rod 55, the first hook 5011 and the second hook 5031 will be forced to open outward. When the first hook 5011 hooks the first support rod 27 and the second hook 5031 hooks the second support rod 28, the grasping mechanism 5 will grasp the filter basket 2. Maintaining this state will allow the extraction and transportation of the filter basket 2 to begin.

[0081] Conversely, when it is necessary to release the gripped filter basket 2, the piston rod of the cylinder or hydraulic cylinder 58 retracts upward, forcing the two central connecting rods 55 to move upward in the waist-shaped groove 571, forcing the first connecting rod 52 and the second connecting rod 54 to open outward around the central connecting rod 55. During the process of the first connecting rod 52 and the second connecting rod 54 opening outward around the central connecting rod 55, the first hook 5011 and the second hook 5031 will be forced to close inward, so that the first hook 5011 moves away from the first support rod 27 and the second hook 5031 moves away from the second support rod 28. At this time, the filter basket 2 is disengaged from the gripping mechanism 5.

[0082] The cylinder or hydraulic cylinder 58 in the gripping mechanism 5 can be controlled by a control device to extend and retract the piston rod, so as to realize automatic control of the gripping mechanism 5. In addition, the gripping mechanism 5 is flexible and reliable in operation and can smoothly grip and release the filter basket 2. Example 3

[0083] This embodiment is designed for the structure of the oscillating device in the filter basket 2 and the needle separator 3 described in Embodiment 1.

[0084] like Figure 5 and Figure 7 As shown, the structure of the filter basket 2 in this embodiment includes: a filter basket frame; the structure of the filter basket frame includes: a left support plate 21 and a right support plate 22; the left support plate 21 and the right support plate 22 are connected by several connecting beams 25 to form a three-dimensional frame structure.

[0085] The filter plate 26 is encapsulated on the bottom, front and rear of the three-dimensional frame structure, and the left end of the filter plate 26 is connected to the left support plate 21, and the right end of the filter plate 26 is connected to the right support plate 22; the filter hole group is composed of the filter holes on the filter plate 26.

[0086] In this embodiment, the filter plate 26 can be a single filter plate or it can be composed of several filter plates spliced ​​together.

[0087] like Figure 5 and Figure 6 As shown, the structure of the swing device described in this embodiment includes: a swing frame 7 that can support the filter basket 2; A support shaft is provided at the upper center of the left end and the upper center of the right end of the swing frame 7, respectively: a left support shaft 73 and a right support shaft 74. Both support shafts are placed horizontally and coaxially. The two support shafts are supported in the filter box 31 by their respective first bearing groups, thereby suspending the swing frame 7 in the filter box 31. Either support shaft is driven by the swing drive mechanism 30. Under the drive of the swing drive mechanism 30, the swing frame 7 swings back and forth without colliding with the filter box 31.

[0088] This embodiment uses the swing drive mechanism 30 driving the left support shaft 73 as an example for explanation. Figure 5 and Figure 8 As shown, the structure of the swing drive mechanism 30 is as follows: a mounting base 32 is fixedly installed on the outer wall of the filter box 31 located at the left support shaft 73, and the first drive motor is fixed on the mounting base 32; one end of the crank 33 is fixed to the motor shaft 36 of the first drive motor, the other end of the crank 33 is hinged to one end of the intermediate connecting rod 34, the other end of the intermediate connecting rod 34 is hinged to one end of the rocker arm 35, the other end of the rocker arm 35 is fixedly connected to the corresponding support shaft, and the crank 33, the intermediate connecting rod 34, and the rocker arm 35 constitute a crank-rocker mechanism.

[0089] The crank-rocker mechanism is a type of conventional four-bar linkage, so its working principle will not be elaborated here. When the first drive motor drives the crank 33 to rotate a full circle, the rocker arm 35 swings back and forth, thus achieving the purpose of making the swing frame 7 swing back and forth. During the back and forth swing of the swing frame 7, it is equivalent to swinging the filter basket 2 back and forth to remove the magnetic needles from the filter basket 2.

[0090] like Figure 5 and Figure 6 As shown, the structure of the swing frame 7 in this embodiment includes: a left swing plate 71 and a right swing plate 72; the bottom of the left swing plate 71 and the bottom of the right swing plate 72 are connected by at least two bottom support beams 75; the front part of the left swing plate 71 and the front part of the right swing plate 72 are connected by at least one front support beam 76; the rear part of the left swing plate 71 and the rear part of the right swing plate 72 are connected by at least one rear support beam 77.

[0091] A more preferred embodiment is that there are preferably two bottom support beams 75. There is preferably one front support beam 76, typically located above the front of the left swing plate 71 and the right swing plate 72. There is preferably one rear support beam 77, typically located above the rear of the left swing plate 71 and the right swing plate 72.

[0092] A more preferred embodiment is that the front support beam 76, the rear support beam 77, and the two bottom support beams 75 are symmetrically distributed on the left and right sides of the vertical center plane of the swing frame 7 that is perpendicular to the left swing plate 71.

[0093] A more preferred embodiment is that both the left swing plate 71 and the right swing plate 72 are planar frame plate structures with several hollowed-out areas.

[0094] A more preferred embodiment is that the left swing plate 71 is symmetrically distributed with respect to the center line, and the left swing plate 71 and the right swing plate 72 have the same shape, structure and size.

[0095] The above-mentioned swing device 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.

[0096] like Figure 7 , Figure 10 and Figure 11 As shown, in this embodiment, the filter basket 2 has at least two front resting parts 23 at the front and at least two rear resting parts 24 at the rear. When the filter basket 2 is placed on the swing frame 7, the bottom of the filter basket 2 rests on each bottom support beam 75, each front resting part 23 rests on the uppermost front support beam 76, and each rear resting part 24 rests on the uppermost rear support beam 77.

[0097] The front shelving section 23 and the rear shelving section 24 have the same structure, shape and size, and can be a hook-shaped structure, shelf structure, etc.

[0098] A more preferred embodiment is that the filter basket 2 is symmetrically distributed on the left and right sides relative to the vertical center plane of the filter basket 2 that is perpendicular to the left support plate 21, and is also symmetrically distributed front and back relative to the vertical center plane of the filter basket 2 that is parallel to the left support plate 21.

[0099] A more preferred embodiment is that there are two front support portions 23, distributed on the front end of the left support plate 21 and the front end of the right support plate 22. There are two rear support portions 24, distributed on the rear end of the left support plate 21 and the rear end of the right support plate 22.

[0100] 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 4

[0101] The magnetic polishing machine 1 described in this embodiment is an existing mature product, including: a housing 11 and a turntable disposed within the housing 11, with a polishing barrel 8 mounted above the housing 11 via a frame. Several first electromagnets are spaced apart on the turntable, some of which have N poles when energized, while the remaining first electromagnets have P poles. Typically, adjacent first 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 8, energizing all the first electromagnets and causing the turntable to rotate. The turntable can alternate between forward and reverse rotation. During the rotation of the turntable, the magnetic needles inside the polishing barrel 8 alternately jump under the magnetic effect, continuously impacting the workpiece. Furthermore, the jumping magnetic needles driven by the first electromagnets also drive the movement of the mixture. Through the high-frequency impact of the magnetic needles and the rotation of the mixture, the workpiece is deburred and polished.

[0102] However, due to the gravity of the workpiece itself, and the flat bottom of the polishing barrel 8, it is difficult to flip the workpiece that is attached to the bottom of the polishing barrel 8. As a result, the surface of the workpiece that is attached to the bottom of the polishing barrel 8 cannot contact the magnetic needle for deburring and polishing.

[0103] This embodiment addresses the aforementioned problems by designing the polishing bucket 8 as follows: Figure 15 As shown, a number of spaced protrusions are provided on the bottom surface of the polishing barrel 8, 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.

[0104] The protrusion can be formed by stamping. The shape of the protrusion can be hemispherical or other shapes, wherein the protrusion is preferably hemispherical.

[0105] A better option is: such as Figure 15 As shown, the protrusions on the bottom surface of the polishing barrel 8 are composed of a central protrusion 83 and several peripheral protrusions 84 of the same shape and size. The hemispherical diameter of the central protrusion 83 is larger than that of the peripheral protrusions 84, and the peripheral protrusions 84 are evenly distributed on the bottom surface of the polishing barrel 8 except for the central protrusion 83.

[0106] At this time, the concave surfaces between the protrusions on the bottom surface of the polishing barrel 8 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 8 can also be struck by the magnetic needles to perform deburring and polishing operations, further improving the deburring and polishing effect of the workpiece.

[0107] Furthermore, the polishing barrel 8 is mounted on top of the housing 11 via the frame 4 in the following manner: Figure 5 and Figure 15As shown, two tilting arms 81 are fixedly installed on the polishing barrel 8, and the two tilting arms 81 are fixedly connected to the tilting rod 91. The tilting rod 91 is supported on the frame 4 by a second bearing assembly. A second drive motor 92 is fixedly installed on the frame 4, and the motor shaft of the second drive motor 92 is fixedly connected to the tilting rod 91. Driven by the second drive motor 92, the polishing barrel 8 can tilt and pour out all the material in the polishing barrel 9 into the filter basket 2 in the corresponding filter box 31.

[0108] A better option is: such as Figure 5 and Figure 15 As shown, an extended discharge end 82 is provided at the top of the polishing barrel 8. After the polishing barrel 8 is tilted, all the material inside the polishing barrel 8 is discharged through the extended discharge end 82. The filter basket 2 in the filter box 31 corresponding to the polishing barrel 8 can receive the material discharged from the extended discharge end 82. The extended discharge end 82 facilitates the transition of material from the polishing barrel 8 to the filter basket 2 in the corresponding filter box 31, and can effectively prevent material from spilling out of the filter basket 2 during the material transition process.

[0109] 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.
