[0001] This utility model relates to the field of fermentation equipment technology, specifically to a permanent magnet grinding device. Background Technology

[0002] Magnets are objects that can generate magnetic fields, attracting magnetic materials such as iron, nickel, and cobalt. In the magnet manufacturing process, to obtain precise dimensions and improve performance, roughly machined magnets require further finishing processes, namely, grinding and machining of their external dimensions to meet specific requirements.

[0003] A prior art magnetic polishing device, such as the utility model patent document with authorization announcement number "CN220921786U" and patent name "A magnetic surface chamfering and polishing device", discloses a magnetic polishing device including a table, a mounting platform installed on the top surface of the table, a set of slides provided on the top of the mounting platform, a sliding block installed in the slides, a first electric cylinder installed on one side of the mounting platform, the output end of the first electric cylinder passing through the mounting platform and connected to the sliding block, a chamfering mechanism installed on the top of the sliding block, a cavity provided on the surface of the mounting platform, a fixing block installed in the middle of the cavity, a clamp installed on the top of the fixing block, and a centering mechanism installed inside the cavity.

[0004] The aforementioned patent document describes the grinding operation of the two ends of the magnet using two chamfering mechanisms. When the operator needs to grind the outer wall of the magnet, the grinding operation must be performed using other equipment. This results in the operator having to clamp and position the magnet multiple times when grinding the magnet, which reduces production efficiency. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by proposing a permanent magnet grinding device. This device solves the technical problem mentioned in the background art, where the existing grinding device grinds both ends of the magnet through two chamfering mechanisms. When the operator needs to grind the outer wall of the magnet, other equipment is required for the grinding operation, resulting in the operator having to clamp and position the magnet multiple times during the grinding process, which reduces production efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A permanent magnet grinding device includes a worktable with two first grinding rollers rotatably mounted on it for grinding the outer wall of the permanent magnet, the axes of which are parallel to each other.

A support frame is provided on the worktable, and a plurality of rollers are slidably mounted on the support frame for pushing the permanent magnet and abutting against the two first grinding rollers. Two third grinding rollers are slidably mounted on the support frame for grinding both ends of the permanent magnet.

[0008] Working principle:

[0009] First, the operator places the magnet to be polished between two first polishing rollers. Then, the operator moves the rollers vertically downwards until several rollers come into contact with the outer surface of the magnet. Next, the operator starts the two first polishing rollers to rotate, using the friction between the rollers and the magnet to polish the outer wall. Then, the operator moves the second polishing roller to the hole in the magnet to polish the inner wall. Finally, the operator simultaneously moves two third polishing rollers towards both ends of the magnet, polishing the ends of the magnet, thus completing the polishing operation on multiple surfaces of the magnet.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, a first grinding roller and a roller are provided. The rotation of the first grinding roller and the cooperation of the roller can make the magnet to be ground rotate between the three and the magnet axis is parallel to the axes of the three.

[0012] Secondly, a second grinding roller is provided, which can be inserted into the hole along the axis of the magnet to grind the inner wall of the magnet when the magnet rotates.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example:

[0020] like Figure 1 and Figure 2 As shown, a permanent magnet grinding device includes a worktable 1. Two feed plates 29 inclined towards two first grinding rollers 2 are fixed on the worktable 1. An inclined partition plate 30 is provided between the two feed plates 29. A third hydraulic cylinder 31 for driving the partition plate 30 to move vertically is fixed on the worktable 1. In the initial state, the permanent magnet workpiece passes sequentially through the feed plate 29 away from the first grinding roller 2, the partition plate 30, and the feed plate 29 close to the first grinding roller 2. The third hydraulic cylinder 31 drives the partition plate 30 to move vertically, which pushes the magnet on the partition plate 30 to the feed plate 29 close to the first grinding roller 2 and slides it onto the two first grinding rollers 2.

[0021] like Figure 1 and Figure 2 and Figure 3 As shown, a support frame 5 is provided on the workbench 1. Several rollers 6 are slidably provided on the support frame 5 for pushing the permanent magnet and abutting against the two first grinding rollers 2. A second hydraulic cylinder 25 is fixed on the support frame 5, and the extension end of the second hydraulic cylinder 25 faces the workbench 1. A fixed plate 26 is fixed on the extension end of the second hydraulic cylinder 25. Several rollers 6 are all provided on the fixed plate 26. When the magnet is located between the two first grinding rollers 2, the fixed plate 26 and rollers 6 are driven by the second hydraulic cylinder 25 to move toward the magnet and abut against the outer wall of the magnet.

[0022] like Figure 1 and Figure 2As shown, two first grinding rollers 2 for grinding the outer wall of permanent magnets are rotatably mounted on the worktable 1, and the axes of the two first grinding rollers 2 are parallel to each other. A slide rail 8 is fixed on the worktable 1. One of the first grinding rollers 2 is fixed on the worktable 1 through a bearing seat, and the other first grinding roller 2 is slidably mounted on the slide rail 8 through a bearing seat. A first motor 9 is fixed on the worktable 1. A first sprocket 10 is fixed on one of the first grinding rollers 2 away from the slide rail 8 and on the output end of the first motor 9. A first chain 11 is fitted around the outer ring of the two first sprockets 10. The motor drives the sprockets and the chain, and the first grinding rollers 2 fixed on the worktable 1 rotate accordingly. Thus, the magnet rotates due to friction under the contact of the two first grinding rollers 2 and the roller 6, and the first grinding rollers 2 can grind the outer wall of the magnet.

[0023] like Figure 1 and Figure 2 As shown, a movable stage 3 is slidably mounted on the worktable 1. A second grinding roller 4 for grinding the inner wall of the permanent magnet is rotatably mounted on the movable stage 3, and the axis of the second grinding roller 4 is parallel to the axes of the two first grinding rollers 2. A first guide rail 12 is fixedly mounted on the worktable 1, and the movable stage 3 is slidably mounted on the first guide rail 12. A first electric push rod 13 is fixedly mounted on the worktable 1, and the telescopic end of the first electric push rod 13 is fixedly connected to the movable stage 3. The first electric push rod 13 can drive the movable stage 3 to move on the first guide rail 12, thereby changing the position of the movable stage 3 and driving the second grinding roller 4 to move towards the magnet. A second guide rail 14 is fixedly mounted on the movable stage 3, and a lifting mechanism is slidably mounted on the second guide rail 14. A first hydraulic cylinder 16 for vertically moving the lifting platform 15 is fixed on the platform 15 and the movable platform 3. The first hydraulic cylinder 16 can drive the lifting platform 15 to move vertically, so that the second grinding roller 4 on the lifting platform 15 can be in close contact with the inner wall of the magnet. It should be noted that the diameter of the end of the second grinding roller 4 is smaller than the diameter of the inner wall of the magnet. The second grinding roller 4 is rotatably mounted on the lifting platform 15. A second motor 17 is fixed on the lifting platform 15. A second sprocket 18 is fixed at both the output end of the second motor 17 and the end of the second grinding roller 4. A second chain 19 is sleeved on the two second sprockets 18. The second motor 17 and the cooperation of the sprockets and chains can drive the second grinding roller 4 to perform grinding operation on the inner wall of the magnet.

[0024] like Figure 1 and Figure 2 and Figure 3As shown, two third grinding rollers 7 for grinding the ends of the permanent magnet are slidably mounted on the support frame 5. A bidirectional screw 20 is mounted on the support frame 5, and a guide rod 21 is fixedly mounted on the support frame 5. Moving plates 22 are threadedly connected to the two threaded sections of the bidirectional screw 20. Both moving plates 22 are slidably connected to the guide rod 21. A drive motor 23 for driving the bidirectional screw 20 is fixedly mounted on the support frame 5. The two third grinding rollers 7 are rotatably mounted on the two moving plates 22 respectively. A third motor 24 for driving the two third grinding rollers 7 to rotate is fixedly mounted on the two moving plates 22 respectively. The bidirectional screw 20 drives the moving plates 22 on the two threaded sections to move closer to the magnet ends under the action of the guide rod 21. The third grinding rollers 7 can be driven to rotate by the third motor 24. It should be noted that the two third grinding rollers 7 rotate in opposite directions when grinding the magnet ends.

[0025] like Figure 1 and Figure 2 As shown, a discharge channel 27 is provided inside the workbench 1. The inlet end of the discharge channel 27 is located below the two first grinding rollers 2, and the outlet end of the discharge channel 27 is connected to the outside. A second electric push rod 28 is fixed on the workbench 1 and is used to drive the first grinding rollers 2 on the slide rail 8 to move. After the magnet between the two first grinding rollers 2 is finished, the operator starts the second hydraulic cylinder 25 to drive the roller 6 away from the magnet, and then starts the second electric push rod 28. The second electric push rod 28 drives one of the first grinding rollers 2 to move on the slide rail 8. When the distance between the two first grinding rollers 2 is greater than the diameter of the magnet, the magnet can fall into the discharge channel 27 and be discharged to the outside.

[0026] Working principle:

[0027] The magnet slides onto the partition plate 30 through the feed plate 29 on one side. When the magnet needs to be polished, the third oil cylinder 31 drives the partition plate 30 to rise. The partition plate 30 lifts the magnet vertically. When the upper surface of the partition plate 30 is horizontal with the feed plate 29 on the side near the worktable 1, the magnet slides through the feed plate 29 between the two first polishing rollers 2.

[0028] Then, the second cylinder 25 drives the fixed plate 26 to press down, so that the roller 6 abuts against the upper surface of the workpiece and forms a three-point clamp with the first grinding roller 2. The first motor 9 drives one of the first grinding rollers 2 to rotate through the sprocket and chain. Under the action of friction, the magnet rotates between the two first grinding rollers 2 and the roller 6, so that the two first grinding rollers 2 can perform grinding operation on the outer wall of the magnet.

[0029] Then the operator starts the first electric push rod 13, which pushes the moving table 3 along the first guide rail 12 toward the magnet and extends into the inner wall of the magnet. Then the first hydraulic cylinder 16 drives the lifting table 15 to move and adjust the distance between the second grinding roller 4 and the inner wall of the magnet. The second motor 17 drives the second grinding roller 4 to rotate through the sprocket and chain, so that the second grinding roller 4 can perform grinding operation on the inner wall of the magnet.

[0030] The operator then starts the drive motor 23, which drives the bidirectional screw 20 to rotate, causing the moving plates 22 on the two threaded sections of the bidirectional screw 20 to move towards each other along the guide rod 21 and make the third grinding roller 7 abut against the end face of the magnet. The third motor 24 drives the third grinding roller 7 to grind both ends of the workpiece.

[0031] After the magnet is polished, the operator starts the second electric push rod 28, which drives one of the first polishing rollers 2 to move on the slide rail 8. When the distance between the two first polishing rollers 2 is greater than the diameter of the magnet, the magnet falls into the discharge channel 27 above the worktable 1, and the polished magnet is discharged to the outside through the discharge channel 27.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
