At the same time, through the cooperation between the trigger rod, the limit block and the pull rope, the trigger rod contacts the trigger block and rotates, so that the limit block moves backward. When the limit block does not limit the limit pressure rod, the limit pressure rod rotates, further causing the second sliding rod to move to the left, thereby clamping the cylindrical regenerated NdFeB, making it convenient for the grinding wheel to grind the top and bottom surfaces of the cylindrical regenerated NdFeB, and increasing the applicability of the device when used.

[0018] The present invention adopts a design in which a control mechanism is coordinated with a discharging device. Through the mutual coordination between the rotating block and the placement groove and the inclined groove, only one cylindrical regenerated NdFeB can enter the placement groove when the rotating block rotates, thereby increasing the stability of the device during use. When the limiting pressure rod is rotated, the rotating block is rotated, further allowing the cylindrical regenerated NdFeB in the placement groove to be automatically put between the arc-shaped clamping block and the vertical portion on the left side of the concave block, thereby increasing the convenience of the device during use.

Support legs 15 are provided on the left and right sides of the lower ends of the two device brackets 1, and the connection relationship between the two device brackets 1 and the multiple support legs 15 is a fixed connection.

[0033] Specifically, a first support block 16 is provided in the middle of the upper end of the two device brackets 1, and the connection relationship between the device bracket 1 and the first support block 16 is a fixed connection. The two first support blocks 16 are used to support two grinding wheels 17. A grinding wheel 17 is provided at one end of the two first support blocks 16 close to each other.

[0034] Furthermore, in order to clamp the cylindrical regenerated NdFeB that needs to be polished, as shown in FIG2-10, the clamping mechanism 2 includes a first mounting block 21, and the connection relationship between the chain plate of the transmission chain 13 in contact with the first mounting block 21 and the first mounting block 21 is a fixed connection. The transmission chain 13 is used to transmit multiple clamping mechanisms 2. An extension rod 22 is provided on the left side of the upper end of the first mounting block 21. The connection relationship between the extension rod 22 and the first mounting block 21 is a fixed connection. The extension rod 22 is provided on the left side of the upper end of the first mounting block 21. The rod 22 is used to support the concave block 24. The concave block 24 is provided at the upper end of the extension rod 22. The connection between the extension rod 22 and the concave block 24 is a fixed connection. The concave block 24 is used to install the mounting tube 25 and cooperate with the arc-shaped clamping block 28 to clamp the cylindrical regenerated NdFeB. The rear end of the extension rod 22 is provided with a sliding groove that is compatible with the limiting pressure rod 35 located at the bottom to prevent the extension rod 22 from limiting the limiting pressure rod 35, thereby affecting the stability of the device during operation.

[0035] Specifically, the left end of the vertical portion of the concave block 24 is provided with two mounting tubes 25, and the connection relationship between the two mounting tubes 25 and the concave block 24 is a fixed connection. A first return spring 26 is provided on the right side of the inner cavity of the mounting tube 25, and the connection relationship between the right side of the inner cavity of the mounting tube 25 and the first return spring 26 is a fixed connection. A first sliding rod 27 is provided on the left end of the first return spring 26, and the connection relationship between the first return spring 26 and the first sliding rod 27 is a fixed connection. The connection relationship between the first sliding rod 27 and the mounting tube 25 is a sliding connection. The first sliding rod 27 is connected to the first return spring 26 and the mounting tube 25 through mutual matching. The arc-shaped clamping block 28 is closed, thereby pushing the arc-shaped clamping block 28 to move to the left, further clamping the cylindrical regenerated NdFeB. A first connecting rod is connected between the two first sliding rods 27, and the connection relationship between the two first sliding rods 27 and the first connecting rod is a fixed connection. The first connecting rod is used for the connection between the two first sliding rods 27 and the installation of the second sliding rod 29. The left ends of the two first sliding rods 27 are jointly provided with an arc-shaped clamping block 28, and the connection relationship between the two first sliding rods 27 and the arc-shaped clamping block 28 is a fixed connection. The arc-shaped clamping block 28 cooperates with the vertical part of the concave block 24 on the left to clamp the cylindrical regenerated NdFeB.

[0036] Specifically, a second sliding rod 29 is provided at the upper end of the first connecting rod, and the second sliding rod 29 passes downward through the horizontal part of the concave block 24. The connection relationship between the second sliding rod 29 and the first connecting rod is a fixed connection, and the connection relationship between the second sliding rod 29 and the concave block 24 is a sliding connection. The second sliding rod 29 cooperates with the limiting pressure rod 35 to drive the first sliding rod 27 to move to the right. A trigger block 291 is provided at the rear part of the right side of the lower end of the horizontal part of the concave block 24, and the connection relationship between the trigger block 291 and the concave block 24 is a fixed connection.

[0037] Furthermore, in order to enable the second sliding rod 29 to adjust the distance between the arc-shaped clamping block 28 and the vertical portion on the left side of the concave block 24, as shown in Figure 4-10, the control mechanism 3 includes a device box 31, and the connection relationship between the device box 31 and the device bracket 1 is a fixed connection. A first through-groove 32 is provided on the right side of the front side of the inner cavity of the device box 31. The first through-groove 32 is used for the installation of the trigger rod 33. The inner cavity of the first through-groove 32 is provided with a trigger rod 33 adapted to the trigger block 291. The connection relationship between the first through-groove 32 and the trigger rod 33 is a rotational connection. The trigger rod 33 cooperates with the trigger block 291 to enable the clamping mechanism 2 to move to the left. When the first reset spring 26 is compressed to its shortest state, the trigger block 291 contacts the trigger rod 33, so that the cylindrical regenerated neodymium magnet dropped into the placement slot 47 can be clamped by the arc-shaped clamping block 29 and the concave block 24. Two second through-grooves 34 are provided on the left side of the front side of the inner cavity of the device box 31, which are adapted to the second sliding rod 29. The second through-grooves 34 are used for the installation of the limiting pressure rod 35. The two second through-grooves 34 are each provided with a limiting pressure rod 35. The connection relationship between the second through-grooves 34 and the limiting pressure rod 35 is a rotating connection.

[0038] Specifically, a second connecting rod is provided between the two limiting pressure rods 35. The two limiting pressure rods 35 are used to limit the second sliding rod 29 so that when the first mounting block 21 moves to the left, the second sliding rod 29 will not move, which is convenient for the placement of the cylindrical regenerated NdFeB. The connection relationship between the two limiting pressure rods 35 and the second connecting rod is a fixed connection. Two second support blocks 36 are provided in the inner cavity of the device box 31. The connection relationship between the two second support blocks 36 and the device box 31 is a fixed connection. The second support block 36 is used to facilitate the installation of the limit block 37 and supports the limit block 37. A limit block 37 is provided between the two second support blocks 36. The connection relationship between the limit block 37 and the two second support blocks 36 is a sliding connection. The limit block 37 is used to limit the limit pressure rod 35, so that when the trigger rod 33 is not in contact with the trigger block 291, the limit pressure rod 35 will not rotate, and further when the first installation block 21 moves to the left, the second sliding rod 29 will not move.

[0039] Specifically, a pull rope 38 is connected between the trigger rod 33 and the limit block 37, and the trigger rod 33 and the limit block 37 cooperate through the pull rope 38, so that the trigger rod 33 contacts the trigger block 291 and rotates, causing the limit block 37 to move backward. An annular spring 39 is connected between the lower limit pressure rod 35 and the front side surface of the inner cavity of the device box 31, and the annular spring 39 is located on the left side of the lower limit pressure rod 35. The connection relationship between the left annular spring 39 and the lower limit pressure rod 35 and the front side surface of the inner cavity of the device box 31 is fixedly connected. An annular spring 39 is also connected between the trigger rod 33 and the front side surface of the inner cavity of the device box 31. The connection relationship between the right annular spring 39 and the trigger rod 33 and the front side surface of the inner cavity of the device box 31 is fixedly connected. The two annular springs 39 cooperate with each other to facilitate the resetting of the trigger rod 33 and the limit pressure rod 35.

[0040] Specifically, when the clamping mechanism 2 rotates downward, when the trigger block 291 contacts the trigger rod 33 located at the bottom, the second sliding rod 29 moves to the left relative to the first mounting block 21 through the mutual cooperation between the limiting pressure rod 35 and the trigger block 291, thereby causing the polished cylindrical regenerated NdFeB to fall.

[0041] Furthermore, in order to enable the device to automatically deliver cylindrical regenerated NdFeB, as shown in Figures 6-10, the discharging device 4 includes a second mounting block 41. The connection relationship between the second mounting block 41 and the device box 31 is a fixed connection. An inclined groove 42 is provided on the upper end of the second mounting block 41, and the left side of the bottom surface of the inner cavity of the inclined groove 42 is tilted downward to facilitate the cylindrical regenerated NdFeB to enter the placement groove 47. A mounting groove 43 is provided on the left side of the bottom surface of the inner cavity of the inclined groove 42. The mounting groove 43 is used for the installation of the rotating block 44. The mounting groove 43 is a circle with a notch to facilitate the cylindrical regenerated NdFeB in the placement groove 47 to fall out. A rotating block 44 is provided in the mounting groove 43, and the connection relationship between the mounting groove 43 and the rotating block 44 is a rotating connection. A plurality of placement grooves 47 are provided in a circular array on the side away from the center at the front end of the rotating block 44. The plurality of placement grooves 47 cooperate with each other to facilitate the single placement of cylindrical regenerated NdFeB. A one-way ratchet 45 for driving the rotating block 44 is provided at the rear end of the second mounting block 41. The connection relationship between the second mounting block 41 and the one-way ratchet 45 is a rotating connection, and the connection relationship between the rotating block 44 and the output end of the one-way ratchet 45 is a fixed connection. A gear set is connected between the one-way ratchet 45 and the limiting pressure rod 35 located at the upper part.

[0042] Specifically, the discharge device 4, the arc-shaped clamping block 28 and the concave block 24 are all made of non-metallic materials to prevent the device from being adsorbed by the magnetic field of the neodymium magnet during use, thereby preventing the neodymium magnet from moving and affecting the stability of the device during use.

[0043] It should be noted that the specific installation and control methods of the sprocket 12, transmission chain 13, drive motor 14, DC motor 18, etc. in the present invention are conventional designs in the prior art and will not be elaborated in detail in the present invention.

[0044] The specific implementation method is as follows: when in use, first place the cylindrical regenerated NdFeB that needs to be processed in the inclined groove 42, and the driving motor 14 drives the sprocket 12 to rotate, thereby transmitting multiple clamping mechanisms 2. When the trigger block 291 contacts the trigger rod 33, the trigger rod 33 rotates. At the same time, the limit block 37 limits the limit pressure rod 35, so that the limit block 37 cannot rotate. Further, when the first mounting block 21 moves to the left, the second sliding rod 29 moves to the right relative to the first mounting block 21, thereby increasing the distance between the arc-shaped clamping block 28 and the vertical portion on the left side of the concave block 24, which facilitates the cylindrical regenerated NdFeB. When the trigger rod 33 is put in, the limit block 37 moves backward through the cooperation with the pull rope 38. When the limit block 37 does not limit the limit pressure rod 35, the limit pressure rod 35 rotates, further causing the second sliding rod 29 to move to the left, thereby clamping the cylindrical regenerated NdFeB. At the same time, when the limit pressure rod 35 rotates, the rotating block 44 is rotated through the gear set, further allowing the cylindrical regenerated NdFeB located in the placement groove 47 to be put between the arc-shaped clamping block 28 and the vertical part on the left side of the concave block 24, and then the two grinding wheels 17 grind the top and bottom surfaces of the cylindrical regenerated NdFeB.

[0045] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
