Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0043] Embodiment 1

[0044] The present embodiment provides an automatic magnetic force polishing and separating equipment, as shown in Figures 1 to 5 Figure, including: rack 1, magnetic force polishing machine 2 and magnetic force separator 3; ​​​

[0045] As shown in Figure 2 and Figure 6 , the magnetic force polishing machine 2 comprises a polishing barrel 21 and a first rotating magnetic field device 22, the first rotating magnetic field device 22 is arranged on the rack 1, the bottom of the polishing barrel 21 is arranged on the top of the first rotating magnetic field device 22, and the first rotating magnetic field device 22 is used to generate a rotating magnetic field to drive the magnetic abrasive in the polishing barrel 21 to rotate;

[0046] The magnetic force separator 3 comprises a separation barrel 31 and a second rotating magnetic field device 32, the second rotating magnetic field device 32 is arranged on the rack 1, the bottom of the separation barrel 31 is arranged on the top of the second rotating magnetic field device 32, and the second rotating magnetic field device 32 is used to generate a rotating magnetic field to drive the magnetic abrasive in the separation barrel 31 to rotate;

[0047] As shown in Figure 5 , the separation barrel 31 is provided with a separation chamber 311 and a recovery chamber 312 below the separation chamber 311, and the separation barrel 31 is provided with a filter hole allowing the magnetic abrasive in the separation chamber 311 to enter the recovery chamber 312, as shown in Figure 1 , the rack 1 is provided with a turnover device 5, and the turnover device 5 is used to overturn the polishing barrel 21, so that the workpiece and the magnetic abrasive in the polishing barrel 21 can be poured into the separation chamber 311.

[0048] The automatic magnetic force polishing and separating equipment provided in the embodiment integrates magnetic force polishing and magnetic force separation. The magnetic force polishing machine 2 generates a rotating magnetic field through the first rotating magnetic field device 22 to promote the magnetic abrasive in the polishing barrel 21 to rotate, thereby polishing the workpiece in the barrel. The magnetic force separator 3 generates a rotating magnetic field through the second rotating magnetic field device 32 to promote the magnetic abrasive in the separation barrel 31 to rotate, so that the magnetic abrasive in the separation chamber 311 is separated from the workpiece under the joint action of gravity and magnetic force and enters the recovery chamber 312 through the filter hole, thereby realizing the automatic separation of the magnetic abrasive and the workpiece after polishing. The turnover device 5 on the rack 1 overturns the polishing barrel 21, so that the workpiece and the magnetic abrasive in the polishing barrel 21 are poured into the separation chamber 311, thereby realizing the automatic process of magnetic force polishing and the separation of the magnetic abrasive and the workpiece after polishing, ensuring the stability of production efficiency and polishing quality, and being applicable to the polishing of various complex components.

[0049] The size of the filter hole must meet the requirements that the magnetic abrasive can pass through, while the polished workpiece cannot pass through, so that the polished workpiece can be screened in the separation chamber 311, and the magnetic abrasive can leak into the recovery chamber 312. The rotating magnetic field drives the magnetic abrasive in the separation chamber 311 to rotate and can exert a downward magnetic force on the magnetic abrasive, so that the magnetic abrasive can be quickly sucked into the recovery chamber 312, thereby completing the separation of the workpiece and the magnetic abrasive.

[0050] Specifically, as shown in Figure 4As shown, the first rotating magnetic field device 22 includes a turntable 41, a thrust ball bearing 42, a motor 43, and a housing 44. A permanent magnet or electromagnet is fixed on the turntable 41. The housing 44 is fixed on the frame 1. The turntable 41, the thrust ball bearing 42, and the motor 43 are arranged inside the housing 44. The motor 43 is fixedly connected to the housing 44.

The polishing barrel 21 is placed on top of the housing 44 of the first rotating magnetic field device 22.

[0051] The structure of the second rotating magnetic field device 32 is the same as that of the first rotating magnetic field device 22, and the separation barrel 31 is placed on top of the outer shell 44 of the second rotating magnetic field device 32. The rotation speed and rotation direction of the rotating magnetic field (corresponding to the speed and direction of the motor 43) are adjusted according to different polishing workpieces. Similarly, the specifications of the magnetic abrasive are also adjusted according to different polishing workpieces.

[0052] Specifically, such as Figure 4 As shown, the flipping device 5 includes a hydraulic cylinder 51 and a movable support 52. The cylinder body of the hydraulic cylinder 51 is vertically fixed on the frame 1. The piston rod end of the hydraulic cylinder 51 is fixedly connected to the movable support 52. A flipping motor 54 is fixedly mounted on the movable support 52. A connecting shaft 211 is provided on the outer periphery of the polishing barrel 21. The connecting shaft 211 is rotatably mounted on the movable support 52 through a support bearing 53. The flipping motor 54 can drive the connecting shaft 211 to rotate. In this embodiment, the output shaft of the flipping motor 54 is directly connected to the connecting shaft 211 through the support bearing 53.

[0053] In this embodiment, the support bearing 53 is mounted on the bearing seat, which is fixed to the movable bracket 52. The hydraulic cylinder 51 extends, driving the movable bracket 52 to rise, so that the polishing barrel 21 rises together with the support bearing 53 (the polishing barrel 21 is lifted from the first rotating magnetic field device 22 to ensure no interference during the flipping). The flipping motor 54 rotates, causing the polishing barrel 21 to tilt, so that the workpiece and magnetic abrasive in the polishing barrel 21 can be poured into the separation chamber 311.

[0054] Preferably, the frame 1 is constructed from aluminum profiles, such as... Figure 1 As shown, the movable bracket 52 is connected to the frame 1 via the corner bracket 8. The movable bracket 52 is fixedly connected to the corner bracket 8. The corner bracket 8 is connected to the frame 1 via bolts and a slider nut. The slider nut is set in the groove of the aluminum profile of the frame 1. The corner bracket 8 slides along the groove via the slider nut, which guides the up-and-down reciprocating movement of the movable bracket 52.

[0055] Specifically, as Figure 5 shown, a screen 7 is further arranged in the separation barrel 31, the screen 7 divides the space in the separation barrel 31 into a separation chamber 311 and a recovery chamber 312, and the screen 7 is provided with filter holes.

[0056] Preferably, a hook 71 is arranged on the outer periphery of the screen 7, which can be hung on the upper edge of the separation barrel 31 to facilitate replacement of the screen 7.

[0057] Preferably, the top of the first rotating magnetic field device 22 arranged on the rack 1 is higher than the top of the second rotating magnetic field device 32 arranged on the rack 1, so that the polishing barrel 21 is higher than the separation barrel 31, facilitating pouring of the workpiece and magnetic abrasive in the polishing barrel 21 into the separation barrel 31.

[0058] In this embodiment, as Figure 6 shown, a first support 11 and a second support 12 lower than the first support 11 are fixed on the rack 1, the first rotating magnetic field device 22 is fixed on the first support 11, and the second rotating magnetic field device 32 is fixed on the second support 12, so that the top of the first rotating magnetic field device 22 is higher than the top of the second rotating magnetic field device 32.

[0059] The automatic magnetic polishing and separation equipment disclosed in the present application has high flexibility and universality, can meet the polishing needs of most complex components, and can improve production efficiency and polishing quality.

[0060] Embodiment 2

[0061] The rotating magnetic field is located below the polishing barrel 21, the magnetic abrasive is affected by the downward magnetic force of the bottom magnetic field, and is concentratedly distributed at the bottom of the polishing barrel 21, which is easy to tightly adhere to the bottom of the polishing barrel 21 to complete polishing, which leads to the existence of polishing dead points for some large-size workpieces.

[0062] The present embodiment provides an automatic magnetic polishing and separation equipment, the main structure of the present embodiment is the same as that of embodiment 1, and the difference between the present embodiment and embodiment 1 is as follows:

[0063] In this embodiment, a plurality of magnetic strips 23 are arranged on the outer periphery of the polishing barrel 21, specifically, as Figure 2 shown, a magnetic strip 23 is pasted on the outer periphery of the polishing barrel 21, which provides upward magnetic force for the magnetic abrasive, so that the magnetic abrasive is no longer concentratedly distributed at the bottom of the polishing barrel 21, and the polishing dead point is avoided as much as possible, and the position and number of the magnetic strip 23 can be adjusted according to the size of the workpiece.

[0064] Embodiment 3

[0065] The embodiment provides an automatic magnetic polishing and separating device, and the main structure of the embodiment is the same as that of embodiment 1, and the embodiment is different from embodiment 1 in that the following point:

[0066] In the embodiment, the first ultrasonic generator 61 is fixed on the polishing barrel 21, and the second ultrasonic generator 62 is fixed on the separating barrel 31.

[0067] The polishing barrel 21 and the separating barrel 31 are filled with liquid medium, and in the embodiment, the liquid medium is alcohol. The alcohol has two effects. Firstly, it can buffer the workpiece and the magnetic abrasive poured into the barrel, so as to reduce the collision between the workpiece and the polishing barrel 21 and the separating barrel 31. Secondly, the alcohol serves as a propagation medium of ultrasonic waves, so that the magnetic abrasive can be uniformly distributed in the polishing barrel 21 under the action of ultrasonic waves, thereby improving the polishing quality of the large-size workpiece, and the residual magnetic abrasive on the surface of the workpiece can also be removed through vibration.

[0068] In actual use, when polishing, the magnetic field and the ultrasonic waves can be applied to the barrel at the same time, when separating the magnetic abrasive and the workpiece, the magnetic field and the ultrasonic waves can be applied to the barrel at the same time, or the ultrasonic waves / magnetic field can be applied first, and then the magnetic field / ultrasonic waves can be applied, and the specific application can be adjusted according to the separation effect.

[0069] According to actual polishing requirements, the outer periphery of the polishing barrel 21 can also be provided with the magnetic strip 23 described in embodiment 2.

[0070] Embodiment 4

[0071] An automatic magnetic polishing and separating method, using the automatic magnetic polishing and separating device described in embodiment 1, comprising the following steps:

[0072] S1: placing the magnetic abrasive and the workpiece to be polished in the polishing barrel 21, and starting the first rotating magnetic field device 22, the rotating magnetic field generated by the first rotating magnetic field device 22 drives the magnetic abrasive in the polishing barrel to rotate, and the workpiece to be polished is polished;

[0073] S2: after polishing, the overturning device 5 overturns the polishing barrel 21, so that the workpiece and the magnetic abrasive in the polishing barrel 21 are poured into the separating chamber 311;

[0074] S3: starting the second rotating magnetic field device 32, the rotating magnetic field generated by the second rotating magnetic field device 32 drives the magnetic abrasive in the separating barrel 31 to rotate, so that the magnetic abrasive enters the recycling chamber 312 under the action of the rotating magnetic field magnetic force and its own gravity, and the polished workpiece remains in the separating chamber 311, thereby completing the separation of the workpiece and the magnetic abrasive. The magnetic abrasive in the recycling chamber 312 can be poured back into the polishing barrel 21 for reuse.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
