[0040] Combination Figure 1 and Figure 2 This invention provides a magnetic grinding machine, including a grinding box 1, multiple abrasive bins 12, a magnetic rotating component 2, and a guide rail assembly 3;

[0041] The grinding box 1 has a grinding groove 11 inside, which is used to place the non-magnetic workpiece to be ground;

[0042] Multiple abrasive chambers 12 are located on the side of the grinding box 1 and are interconnected with the grinding tank 11. The multiple abrasive chambers 12 are separated from the grinding tank 11 by an electrically controlled chamber door. The multiple abrasive chambers 12 are used to hold different types of magnetic abrasives 13.

[0043] The magnetic rotating component 2 is located at the bottom of the grinding box 1 and is used to drive the corresponding magnetic abrasive 13 to move in the grinding tank 11;

[0044] The guide rail assembly 3 is located at the bottom of the grinding box 1, and the magnetic rotating component 2 is mounted on the guide rail assembly 3. The guide rail assembly 3 is used to drive the magnetic rotating component 2 to move at the bottom of the grinding box 1.

[0045] In this embodiment, the grinding box 1 can be rectangular, and the grinding groove 11 inside serves as the grinding space for grinding non-magnetic workpieces; multiple abrasive chambers 12 are protruding outward on the inner walls of opposite sides of the grinding box 1, and the multiple abrasive chambers 12 can be integrally set with the grinding box 1, and the multiple abrasive chambers 12 on the inner walls of opposite sides of the grinding box 1 can be symmetrically distributed; each abrasive chamber 12 is interconnected with the grinding groove 11 by setting an electrically controlled chamber door. The magnetic rotating component 2 can attract the magnetic abrasive 13 inside the grinding box 1 at the bottom of the grinding box 1. The magnetic rotating component 2 can be moved by the guide rail assembly 3, thereby moving the magnetic abrasive 13 inside the grinding box 1. This allows for the selection and use of different types of magnetic abrasive 13 in multiple abrasive chambers 12. The magnetic rotating component 2 is a rotatable magnetic structure. When grinding a workpiece, the magnetic rotating component 2 rotates at the bottom of the grinding box 1 and generates a magnetic field. The magnetic abrasive 13 in the grinding tank 11 moves at high speed under the drive of the magnetic field and generates relative motion with the non-magnetic workpiece in the grinding tank 11, thereby achieving the purpose of grinding the workpiece.

[0046] In this embodiment, multiple abrasive bins 12 that communicate with the grinding tank 11 are set on the grinding box 1 to place different types of magnetic abrasives 13. The magnetic rotating component 2 is moved at any position on the bottom of the grinding box 1 by the guide rail assembly 3. This allows for the movement, recycling, and switching of different types of magnetic abrasives 13, which has the advantages of simple recycling and switching process and high work efficiency.

[0047] In some specific embodiments, combined with Figure 3 and Figure 4 Four abrasive chambers 12 can be provided on each of the opposite inner walls of the grinding box 1. Each of the four abrasive chambers 12 on the inner walls of the two sides is used to hold four different types of magnetic abrasives 13. The same type of magnetic abrasive 13 in two opposite abrasive chambers 12 can be used in different proportions to improve the selectivity of the magnetic abrasive 13. It should be understood that the number of abrasive chambers 12 can be adjusted according to the actual required quantity of the magnetic abrasive 13.

[0048] In some specific embodiments, the magnetic abrasive 13 is a magnetically conductive steel needle, which can be one of four types with diameters of 0.6mm, 0.8mm, 1.0mm, and 1.2mm.

[0049] In some specific embodiments, the entire magnetic polishing machine can be mounted on a base, such as a base mounted on... Figure 2 The side of the grinding box 1 is mounted on the top of the housing 4, and the guide rail assembly 3 can be mounted on the inner wall of the housing 4 or the bottom of the grinding box 1.

[0050] In one embodiment, the magnetic grinding machine further includes a pressure sensor 14 and a solenoid valve 15 disposed at the bottom of each abrasive chamber 12: the solenoid valve 15 is used to provide magnetic attraction force to magnetically fix the magnetic abrasive 13 in the abrasive chamber 12, and the pressure sensor 14 is used to detect the gravity signal at the bottom of the abrasive chamber 12.

[0051] In this embodiment, when the solenoid valve 15 is energized, it can generate a magnetic attraction force on the magnetic abrasive 13 in the abrasive chamber 12 and hold the magnetic abrasive 13 in place, thus ensuring that the magnetic abrasive 13 remains stable in the abrasive chamber 12; when the solenoid valve 15 is de-energized, the magnetic attraction force on the magnetic abrasive 13 in the abrasive chamber 12 disappears and the magnetic abrasive 13 is released.

[0052] Based on this, it is understandable that when it is necessary to recycle the currently used abrasive, the guide rail assembly 3 drives the magnetic rotating component 2 to move the currently used magnetic abrasive 13 to the corresponding abrasive bin 12, the corresponding solenoid valve 15 is energized and attracts the currently used magnetic abrasive, and then the corresponding electrically controlled bin door is closed, thus completing the recycling of the currently used magnetic abrasive 13.

[0053] It is understandable that when it is necessary to switch abrasives, the electrically controlled compartment door corresponding to the magnetic abrasive 13 to be used is opened, the guide rail assembly 3 drives the magnetic rotating part 2 to move to the abrasive compartment 12 corresponding to the magnetic abrasive 13 to be used, the corresponding solenoid valve 15 is de-energized and releases the magnetic abrasive 13 to be used, and the magnetic rotating part 2 then attracts the magnetic abrasive 13 to be used. Then, the guide rail assembly 3 drives the magnetic rotating part 2 to move the grinding tank 11, thereby moving the magnetic abrasive 13 to be used to the grinding tank 11. After the corresponding electrically controlled compartment door is closed, the abrasive switching is completed.

[0054] In this embodiment, when the solenoid valve 15 is energized and attracts the magnetic abrasive 13 in the abrasive bin 12, pressure is generated at the bottom of the abrasive bin 12. At this time, the pressure sensor 14 can detect a gravity signal. When the magnetic abrasive 13 in the abrasive bin 12 is moved out by the magnetic rotating part 2, the pressure sensor 14 can detect no gravity signal. That is, the usage status of the magnetic abrasive 13 in the abrasive bin 12 can be detected by the pressure sensor 14 at the bottom of each abrasive bin 12.

[0055] In some embodiments of the magnetic rotating component 2, the magnetic rotating component 2 includes a fixed motor 21 and a magnetic pole 22; the fixed motor 21 is mounted on the guide rail assembly 3; the magnetic pole 22 is mounted on the rotating shaft of the fixed motor 21 and corresponds to the bottom of the grinding chamber 1. By driving the magnetic pole 22 to rotate through the fixed motor 21, a magnetic field is generated at the bottom of the grinding tank 11 and acts on the magnetic abrasive 13, thereby causing relative motion between the magnetic abrasive 13 and the non-magnetic workpiece within the grinding tank 11 and achieving the purpose of grinding the workpiece.

[0056] The guide rail assembly 3 is described in detail below:

[0057] In some embodiments of the guide rail assembly 3, the guide rail assembly 3 includes a first guide rail assembly 3 and a second guide rail assembly 3; the first guide rail assembly 3 and the second guide rail assembly 3 are arranged vertically and alternately upwards along the height direction; the second guide rail assembly 3 is mounted on the first guide rail assembly 3, and the first guide rail assembly 3 is used to drive the second guide rail assembly 3 to move along the length direction of the first guide rail assembly 3; the magnetic rotating component 2 is disposed on the second guide rail assembly 3, and the second guide rail assembly 3 is used to drive the magnetic rotating component 2 to move along the length direction of the second guide rail assembly 3.

[0058] In this embodiment, the length direction of the first guide rail assembly 3 can be parallel to the length direction of the grinding box 1, and the length direction of the second guide rail assembly 3 can be parallel to the width direction of the grinding box 1. The first guide rail assembly 3 can drive the second guide rail assembly 3 to move along the length of the grinding box 1, that is, it can drive the magnetic rotating component 2 to move along the length of the grinding box 1. The second guide rail assembly 3 can drive the magnetic rotating component 2 to move along the length direction of the second guide rail assembly 3, that is, it can drive the magnetic rotating component 2 to move along the width direction of the grinding box 1. In this way, the magnetic rotating component 2 can be moved to any position at the bottom of the grinding box 1, thereby enabling the operation of moving, recycling and switching the magnetic abrasive 13 in any abrasive bin 12 at the bottom of the grinding box 1.

[0059] In some embodiments of the first guide rail assembly 3, the first guide rail assembly 3 includes a first track 31, a first rack 32, and a first motor 33; the first track 31 is disposed at the bottom of the grinding box 1; the first rack 32 is sleeved on the first track 31 and can be driven along the length direction of the first track 31; the first motor 33 is disposed at one end of the first track 31, and the shaft of the first motor 33 is meshed with the first rack 32 through a gear; the second guide rail assembly 3 is connected to the first rack 32.

[0060] In this embodiment, the two ends of the first track 31 can be fixedly installed on the inner walls of opposite sides of the housing 4 (or fixed to the bottom of the grinding box 1). The first rack 32 is sleeved on the first track 31. The first motor 33 is fixed to the end of the first track 31 (or fixed to the inner wall of the housing 4). After the shaft of the first motor 33 is connected to the first rack 32 through gear meshing, the corresponding gear is driven to rotate through the shaft of the first motor 33, so that the first rack 32 moves along the length direction of the first track 31, thereby causing the second guide rail assembly 3 to move along the length direction of the first track 31, that is, the magnetic rotating part 2 moves along the length direction of the first track 31.

[0061] In some embodiments of the second guide rail assembly 3, the second guide rail assembly 3 includes a second rail 34, a second rack 35, and a second motor 36; the second rail 34 is connected to the first rack 32; the second rack 35 is sleeved on the second rail 34 and can be driven along the length direction of the second rail 34; the second motor 36 is disposed at one end of the second rail 34, and the shaft of the second motor 36 is meshed with the second rack 35 through a gear; the magnetic rotating element 2 is mounted on the second rack 35.

[0062] In this embodiment, the two ends of the second track 34 can be fixedly installed on the inner walls of opposite sides of the housing 4 (or fixed to the bottom of the grinding box 1). The second rack 35 is sleeved on the second track 34. The second motor 36 is fixed to the end of the second track 34 (or fixed to the inner wall of the housing 4). After the shaft of the second motor 36 is connected to the second rack 35 through gear meshing, the shaft of the second motor 36 drives the corresponding gear to rotate, so that the second rack 35 moves along the length direction of the second track 34, thereby causing the magnetic rotating component 2 installed on the second rack 35 to move along the length direction of the second track 34.

[0070] S507, the control guide rail assembly 3 drives the magnetic rotating part 2 to move to the bottom of the abrasive bin 12 corresponding to the magnetic abrasive to be switched 13 for suction operation, and controls the corresponding electronically controlled bin door to open so as to move the suction magnetic abrasive to be switched 13 to the grinding tank 11 for grinding work.

[0071] Please continue reading. Figure 6 In one embodiment, step S506 includes:

[0072] S601, Control the guide rail assembly 3 to drive the magnetic rotating component 2 to move so as to attract the current magnetic abrasive 13 into the corresponding abrasive bin 12;

[0073] S602, control the solenoid valve 15 at the bottom of the corresponding abrasive chamber 12 to be energized and attract the current magnetic abrasive 13;

[0074] S603. When the pressure sensor 14 at the bottom of the corresponding abrasive bin 12 detects a gravity signal, the corresponding electrically controlled bin door is closed to complete the current magnetic abrasive 13 recycling operation.

[0075] Please continue reading. Figure 7 In one embodiment, step S507 includes:

[0076] S701, the control guide rail assembly 3 drives the magnetic rotating part 2 to move to the bottom of the abrasive chamber 12 corresponding to the magnetic abrasive 13 to be switched;

[0077] S702, De-energize the solenoid valve 15 at the bottom of the corresponding abrasive chamber 12, and open the corresponding electrically controlled chamber door;

[0078] S703, The magnetic abrasive 13 to be switched is attracted by the magnetic rotating part 2 and moved out to the grinding tank 11 for grinding;

[0079] S704. When the pressure sensor 14 at the bottom of the corresponding abrasive chamber 12 detects a zero-gravity signal, the corresponding electrically controlled chamber door is closed.

[0080] Based on the above method embodiments, in order to facilitate the introduction of the method for switching abrasives, this embodiment takes the four types of magnetic abrasives 13 mentioned above as examples, and names them as magnetic abrasive M1, magnetic abrasive M2, magnetic abrasive M3 and magnetic abrasive M4 respectively; the corresponding abrasive chambers 12 are abrasive chamber X1, abrasive chamber X2, abrasive chamber X3 and abrasive chamber X4 respectively.

[0081] Specifically, taking the example of the user selecting magnetic abrasive 13 to be switched to magnetic abrasive M1:

[0082] First, in response to the user-selected magnetic abrasive M1, it is determined whether the pressure sensor 14 at the bottom of the abrasive chamber X1 corresponding to magnetic abrasive M1 detects a zero-gravity signal. If a zero-gravity signal is detected, it means that the current magnetic abrasive 13 used in the grinding tank 11 is the selected magnetic abrasive M1, and the abrasive switching process does not need to be initiated and ends. If the pressure sensor 14 at the bottom of the abrasive chamber X1 detects a gravity signal, the current grinding operation is stopped and the abrasive chamber 12 (assumed to be abrasive chamber X2) with a zero-gravity signal is identified as the pressure sensor 14, that is, the current grinding operation uses magnetic abrasive M2.

[0083] Then, the electrically controlled door of the abrasive chamber X2 is opened, and the magnetic rotating part 2 is moved to the bottom of the abrasive chamber X2 by the guide rail assembly 3, which drives the magnetic abrasive M2 to be recycled into the abrasive chamber X2. The solenoid valve 15 at the bottom of the abrasive chamber X2 is energized to attract the magnetic abrasive M2. After the pressure sensor 14 at the bottom of the abrasive chamber X2 detects the gravity signal, the electrically controlled door of the abrasive chamber X2 is closed, completing the recycling of the magnetic abrasive M2.

[0084] Finally, the electrically controlled door of the abrasive chamber X1 is opened, the solenoid valve 15 at the bottom of the abrasive chamber X1 is de-energized and the magnetic abrasive M1 is released; then the magnetic rotating part 2 is moved to the bottom of the abrasive chamber X1 by the guide rail assembly 3, the magnetic rotating part 2 attracts the magnetic abrasive M1, and then the magnetic rotating part 2 is moved to the grinding tank 11 by the guide rail assembly 3, that is, the magnetic abrasive M1 is moved into the grinding tank 11. At this time, the pressure sensor 14 at the bottom of the abrasive chamber X1 detects the zero gravity signal and controls the electrically controlled door of the abrasive chamber X1 to close, completing the switching of the magnetic abrasive M1.

[0085] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
