Description

Technical Field

[0001] This utility model relates to the technical field of neodymium iron boron processing equipment, and in particular to a rotary feeding structure for neodymium iron boron rods. Background Technology

[0002] Neodymium iron boron (NdFeB) magnets, currently the most powerful permanent magnet material, are widely used in new energy vehicles, wind power generation, consumer electronics, medical devices, and high-end manufacturing. In the processing of NdFeB products, rod stock is a common primary form, typically requiring automated feeding equipment to orderly transport it to subsequent processes such as cutting, grinding, or magnetization. To achieve efficient continuous production, vibratory feeders or pusher-type feeders are commonly used in industry for the directional arrangement and feeding of NdFeB rod stock. These types of equipment are relatively mature in processing small or standard-sized rod stock and can meet the needs of automated production on a certain scale, serving as key auxiliary devices in magnetic material processing production lines.

[0003] In the manufacturing process of NdFeB permanent magnet materials, the rods typically undergo multiple grinding processes to meet subsequent assembly or usage requirements. After grinding the outer diameter (side surface) of the rod, high-precision surface grinding is required on both end faces to ensure that key dimensions such as end face parallelism and surface roughness meet process standards. Since end face grinding requires the workpiece to be precisely clamped and stabilized axially, existing processing equipment usually requires a separate clamping mechanism to perform a series of actions such as positioning, clamping, grinding, and releasing the rod, making efficient continuous operation difficult. Furthermore, the clamping mechanism often requires specialized fixtures, which are not only complex to change and adjust but also have high maintenance costs. Therefore, we propose a rotary feeding structure for NdFeB rods to solve these problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a rotary feeding structure for neodymium iron boron rods, which realizes continuous feeding, precise positioning and continuous connection with the grinding process.

[0005] A rotary feeding structure for NdFeB rods includes a base plate, a support frame, and a feeding hopper. The support frame is fixedly connected to one side of the base plate, and an inclined feeding hopper is fixedly mounted on the top of the support frame. A pair of fixing rings are symmetrically fixed to one side of the discharge end of the feeding hopper, and the top of each fixing ring has a grinding groove. The structure also includes mounting columns and a feeding wheel. Mounting columns are symmetrically fixed to both sides of the base plate, and a feeding wheel rotatably rotates between the mounting columns. The feeding wheel is used to transfer NdFeB rods from the feeding hopper. The feeding wheel includes a mounting shaft, an outer wheel plate, and an inner wheel plate. A mounting shaft is rotatably mounted between the mounting columns on one side via bearings. Two symmetrical outer wheel plates are fixedly connected at intervals on the mounting shaft. An inner wheel plate is provided on the shaft body located between the two outer wheel plates. The outer wheel plates and the inner wheel plates have uniformly spaced grooves on their circumferences. A mounting frame is fixedly mounted on one side of the mounting column, and a motor is fixedly mounted on the mounting frame. The output shaft of the motor is connected to the mounting shaft. A pusher frame for adjusting the position of the inner wheel plate is provided on the side of the feeding wheel away from the motor. A drive component for driving the pusher frame is provided on the mounting column on the other side.

[0006] In a preferred embodiment of this utility model, the pushing frame includes a guide rod, a sliding frame, a ring, and a connecting rod. A guide rod is fixedly connected to the outer wall of one side of the outer wheel plate, and a sliding frame is slidably connected to the guide rod. An arc groove with the same center as the mounting shaft is eccentrically opened on both sides of the outer wheel plate. An inner wheel rod is eccentrically fixedly arranged on the inner wheel plate. A sliding groove is opened on the side of the sliding frame near the inner wheel rod. The inner wheel rod passes through the arc groove and extends into the sliding groove of the sliding frame. A ring is slidably arranged on the mounting shaft, and a connecting rod is hinged between the ring and the sliding frame.

[0007] In a preferred embodiment of the present invention, the driving component includes an electric push rod and a driving block. The electric push rod is fixedly mounted on the mounting column on the side away from the motor. The driving block is connected to the piston rod of the electric push rod. The ring and the driving block are rotatably connected.

[0008] In a preferred embodiment of this utility model, a support wheel block is fixedly provided on the inner side of the two outer wheel plates. The support wheel block is provided with grooves that are uniformly spaced around the circumference and are consistent with the outer wheel plates. The support wheel block is located between the outer wheel plate and the inner wheel plate. The support wheel block is used to support the neodymium iron boron rod material transferred on the outer wheel plate and the inner wheel plate.

[0009] In a preferred embodiment of this utility model, an arc-shaped limiting plate is fixedly provided on the side of the fixing ring away from the feed hopper. The limiting plate is used to limit the NdFeB rod material in the groove of the inner wheel plate, so as to prevent the NdFeB rod material that has been processed on the feeding wheel from slipping out of the groove in advance.

[0010] In a preferred embodiment of this utility model, a discharge hopper is provided at the bottom of the fixing ring at an angle downwards. The discharge hopper is located below the limiting plate. The neodymium iron boron rod material processed on the feeding wheel will fall into the discharge hopper, slide out along the inclined surface of the discharge hopper, and complete the discharge.

[0011] The beneficial effects are: 1. This utility model uses a rotary structure to clamp and transport NdFeB rods one by one to the grinding groove of the fixed ring, so that the two ends of the rods can be continuously aligned with the grinding station during the feeding and conveying process, without the need for additional clamping mechanisms to cooperate with clamping, thereby simplifying the structure of the processing equipment and effectively supporting the efficient processing of NdFeB rods.

[0012] 2. This utility model utilizes a pusher frame and a drive component to control the inner wheel plate to rotate relative to the outer wheel plate, causing the groove to misalign and thus clamping the bar stock. After processing, the inner wheel plate is reset to align the groove, automatically releasing the NdFeB bar stock, thus realizing an automated clamping and release process.

[0020] A rotary feeding structure for NdFeB rods, such as Figures 1-5 As shown, the device includes a base plate 1, a support 2, and a feeding hopper 3. The support 2 is fixedly connected to one side of the base plate 1, and the inclined feeding hopper 3 is fixedly installed on the top of the support 2. The feeding end of the feeding hopper 3 connects to the conveying equipment for NdFeB rods 100. A pair of fixing rings 4 are symmetrically fixed on one side of the discharge end of the feeding hopper 3. The top of the fixing rings 4 has a grinding groove, and a horizontally movable grinding device can be installed at the grinding grooves on both sides of the fixing rings 4. The device also includes mounting columns 5 and a feeding wheel 6. Mounting columns 5 are symmetrically fixed on both sides of the base plate 1, and a feeding wheel 6 is rotatably mounted between the mounting columns 5. The feeding wheel 6 is used to transfer the NdFeB rods 100 from the feeding hopper 3. The feeding wheel 6 includes a mounting shaft 61, an outer wheel plate 62, and... An inner wheel plate 63 is mounted on a mounting shaft 61 via a bearing 51 between the two mounting columns 5. Two symmetrical outer wheel plates 62 are fixedly connected to the mounting shaft 61 at intervals. The outer wheel plates 62 slide against the adjacent fixing rings 4. An inner wheel plate 63 is provided on the shaft between the two outer wheel plates 62 on the mounting shaft 61. The outer wheel plates 62 and the inner wheel plates 63 are evenly spaced with consistent grooves on their circumference. A mounting frame 71 is fixedly provided on one side of the mounting column 5. A motor 7 is fixedly installed on the mounting frame 71. The output shaft of the motor 7 is connected to the mounting shaft 61. A pusher 8 for adjusting the position of the inner wheel plate 63 is provided on the side of the feeding wheel 6 away from the motor 7. A drive component 9 for driving the pusher 8 is provided on the other side of the mounting column 5.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the pusher frame 8 includes a guide rod 81, a sliding frame 82, a ring 83, and a connecting rod 84. The guide rod 81 is fixedly connected to the outer wall of one side of the outer wheel plate 62, and the sliding frame 82 is slidably connected to the guide rod 81. Both outer wheel plates 62 are eccentrically provided with arc grooves 621 concentric with the mounting shaft 61. An inner wheel rod 631 is eccentrically fixed on the inner wheel plate 63. The sliding frame 82 is provided with a sliding groove 821 on the side near the inner wheel rod 631. The inner wheel rod 631 passes through the arc groove 621 and extends into the sliding groove 821 of the sliding frame 82. The ring 83 is slidably provided on the mounting shaft 61, and a connecting rod 84 is hinged between the ring 83 and the sliding frame 82.

[0022] like Figures 1-3As shown, the drive unit 9 includes an electric push rod 91 and a drive block 92. The electric push rod 91 is fixedly installed on the mounting post 5 on the side away from the motor 7. The drive block 92 is connected to the piston rod of the electric push rod 91. The ring 83 and the drive block 92 are rotatably connected.

[0023] like Figures 2-4 As shown, support wheel blocks 64 are fixedly installed on the inner side of the two outer wheel plates 62. The support wheel blocks 64 are evenly spaced around the circumference with grooves that are consistent with the outer wheel plates 62. The support wheel blocks 64 are located between the outer wheel plates 62 and the inner wheel plates 63. The support wheel blocks 64 and the inner wheel plates 63 are slidably attached. The support wheel blocks 64 are used to support the neodymium iron boron rods 100 transferred on the outer wheel plates 62 and the inner wheel plates 63.

[0024] like Figure 3 and Figure 5 As shown, an arc-shaped limiting plate 10 is fixedly installed on the side of the fixing ring 4 away from the feed hopper 3. An air-blowing chip removal device can be connected to the side of the fixing ring 4 closest to the limiting plate 10. The limiting plate 10 is used to limit the NdFeB rod 100 in the groove of the inner wheel plate 63, so as to prevent the NdFeB rod 100 that has been processed on the feeding wheel 6 from slipping out of the groove in advance.

[0025] like Figure 1 and Figure 5 As shown, the bottom of the fixed ring 4 is inclined downward and has a discharge hopper 11. The discharge hopper 11 is located below the limiting plate 10. The neodymium iron boron rod 100 processed on the feeding wheel 6 will fall into the discharge hopper 11, slide out along the inclined surface of the discharge hopper 11 and complete the discharge.

[0026] When grinding is required on both ends of the NdFeB rod 100, the motor 7 is started first. The motor 7 drives the mounting shaft 61, which in turn causes the entire feeding wheel 6 to rotate intermittently. This causes the grooves on the outer wheel plate 62, inner wheel plate 63, and support wheel block 64 to align intermittently with the grinding grooves on the top of the fixing ring 4. The conveying equipment connected to the feeding end of the feeding hopper 3 neatly feeds the NdFeB rod 100 into the feeding hopper 3. Under the action of gravity, the NdFeB rod 100 in the feeding hopper 3 rolls down the slope. When the intermittently rotating feeding wheel 6 stops, a single NdFeB rod 100 will roll precisely into the outer wheel plate 62, inner wheel plate 63, and support wheel block 64. In the slot formed by the grooves on plate 63 and support wheel block 64, motor 7 drives the feeding wheel 6 to rotate through an angle and then pauses intermittently. This cycle repeats, and the neodymium iron boron rod 100 is carried by the groove of the feeding wheel 6 and gradually conveyed upward from the feed hopper 3. During this process, the fixing ring 4 slides against the outer edge of the outer wheel plate 62, which plays an auxiliary limiting role. When the groove of the feeding wheel 6 carrying the neodymium iron boron rod 100 is transferred to the top of the fixing ring 4 and aligned with the grinding groove, motor 7 shuts off intermittently, and the feeding wheel 6 stops precisely. At this time, the neodymium iron boron rod 100 reaches the preset processing position of the grinding equipment.

[0027] When the neodymium iron boron bar 100, which is loaded in the groove of the feeding wheel 6, aligns with the grinding groove at the top of the fixing ring 4, the piston rod of the electric push rod 91 extends, pushing the drive block 92 to slide along the axial direction of the mounting shaft 61. The drive block 92 drives the rotating ring 83 to move. The ring 83 pushes the sliding frame 82 to slide along the guide rod 81 through the connecting rod 84. The movement of the sliding frame 82 causes the sliding groove 821 on it to press against the inner wheel rod 631. Since the inner wheel rod 631 passes through the arc groove 621 on the outer wheel plate 62, under the forced guidance of the arc groove 621, the movement of the inner wheel rod 631 is converted into rotation, thereby driving the inner wheel plate 63 relative to the fixed outer wheel plate 62 and the support wheel. When block 64 rotates, the groove on the inner wheel plate 63 is misaligned with the grooves on the outer wheel plate 62 and the support wheel block 64, clamping the NdFeB rod 100 in the grooves of the support wheel block 64 from both sides, providing stable processing conditions for the external grinding equipment. Subsequently, the grinding end of the grinding equipment simultaneously extends from the grinding grooves of the fixing rings 4 on both sides and grinds both ends of the NdFeB rod 100. After the NdFeB rod 100 is processed, the piston rod of the electric push rod 91 retracts, pulling the drive block 92 to reset. Through the transmission of the ring 83 and the connecting rod 84, the sliding frame 82 is pulled back, and the inner wheel rod 631 moves in the opposite direction under the guidance of the arc groove 621, driving the inner wheel... Plate 63 rotates in the reverse direction to reset, so that the groove of the inner wheel plate 63 is fully aligned with the grooves of the outer wheel plate 62 and the support wheel block 64 again, thereby releasing the clamping of the NdFeB rod 100. Then, the motor 7 starts intermittently again, and the feeding wheel 6 continues to rotate, so that the NdFeB rod 100 in the next groove of the feeding wheel 6 is switched to the grinding position. At this time, one NdFeB rod 100 in the feed hopper 3 continues to roll into the aligned groove of the feeding wheel 6. Then, the electric push rod 91 similarly triggers the inner wheel plate 63, so that all the NdFeB rods 100 in the grooves of the feeding wheel 6 are clamped again, and then the NdFeB rod 100 in the current processing position is ground by the grinding equipment. At this time, the previously polished NdFeB rod 100 is blown clean by an external air-blowing chip removal device to remove the polishing debris from its surface. This process is repeated to continuously feed and polish the NdFeB rod 100. When the polished NdFeB rod 100 on the feeding roller 6 is transferred to the lower half position near the discharge hopper 11, the arc-shaped limiting plate 10 ensures that the NdFeB rod 100 will not slip out of the groove of the feeding roller 6 in advance. The limiting plate 10 can guide the NdFeB rod 100 into the discharge hopper 11. The NdFeB rod 100 finally slides out along the inclined surface of the discharge hopper 11, thus continuously completing the feeding and processing of the NdFeB rod 100.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
