Description

Technical Field

[0001] This utility model relates to the technical field of magnetic material processing, and in particular to a magnetic material chamfering device with multi-angle adjustment. Background Technology

[0002] In the field of magnetic material processing, chamfering is a crucial process for ensuring the quality and performance of magnetic materials. After molding, magnetic materials often have burrs and flash on their edges. Without chamfering, this not only affects the accuracy of assembling the magnetic material with other components, but may also cause sharp edges to scratch operators or damage other parts during subsequent transportation and installation. Moreover, chamfered magnetic materials have a more uniform stress distribution, effectively preventing cracking and breakage caused by stress concentration during use, significantly improving the service life and reliability of magnetic material products. At the same time, it also optimizes the appearance of the magnetic material, meeting the appearance precision requirements of industrial products.

[0003] However, existing magnetic material chamfering devices have the following shortcomings in practical use: In equipment across different industries, magnetic materials often need to be tightly assembled with various components such as metal supports, plastic shells, and coil assemblies. The differences in assembly structures directly determine the required chamfering angle. For example, in the micro-motor industry, rotor magnets need to be embedded in the slots of the motor core. If the core slot opening is designed with an inclination (such as a 30-degree inclination angle), the edge of the magnet needs to be chamfered at a corresponding 30-degree angle to ensure complete fit with the inner wall of the slot during embedding, avoiding loosening or gaps. Otherwise, the magnets may shift during motor operation, causing noise, vibration, or even burnout. In the automotive sensor field, the assembly of the magnetic ring and the housing is often a "stepped nesting" structure. To adapt to the 50-degree inclination step surface of the housing, the edge of the magnetic ring needs to be chamfered at a 50-degree angle to ensure seamless connection of the contact surfaces after assembly, improving the signal detection accuracy of the sensor. If a fixed 45-degree chamfer is still used, the magnetic material and the assembled components will have problems of "sharp corner contact" or "excessive gaps," seriously affecting the overall assembly quality and operational stability of the equipment. Existing magnetic material chamfering devices on the market are typically fixed at 45 degrees, which cannot meet the needs of multi-angle chamfering of magnetic materials. In view of this, the present application proposes a multi-angle adjustable magnetic material chamfering device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-angle adjustable magnetic material chamfering device that can adapt to chamfering requirements of various angles and improve the adaptability and stability of magnetic material products during assembly.

The tensioning component is rotatably mounted on the frame, and the driving component is mounted on the frame. The grinding belt is sleeved on the tensioning component, the output shaft of the driving component, and both ends of the angled component. The tensioning component, the driving component, and the two ends of the angled component are distributed at four corners to collectively tighten the grinding belt in all directions.

[0007] Optionally, the corner component further includes a corner locking block, and an arc-shaped hole is provided on the corner plate. The corner locking block passes through the arc-shaped hole and is screwed to the telescopic block.

[0008] Optionally, the angular member further includes a top plate, which is disposed on the angular plate and located between the two angular wheels. When the push plate pushes the magnetic material to abut against the grinding belt, the grinding belt abuts against the top plate.

[0009] Optionally, the tensioning component includes a top wheel, a rocker arm, a connecting rod, a sleeve, and a tension spring. One end of the rocker arm is rotatably mounted on the frame, one end of the connecting rod is rotatably mounted on the rocker arm, the sleeve is rotatably mounted on the frame and sleeved with the connecting rod, both ends of the tension spring abut against the connecting rod and the sleeve respectively, the top wheel is rotatably mounted on the rocker arm, and the top wheel, the driving component, and the two corner wheels together support the grinding belt.

[0013] Optionally, the positioning component further includes a limiting rod screwed to the push plate, and the pushing spring pushes the push plate to slide closer to the base so that the depth of the magnetic material chamfer is adjustable.

[0018] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0022] like Figures 1 to 7As shown, in one embodiment, a multi-angle adjustable magnetic material chamfering device 1 is disposed on a workbench 10, including a frame 20, an adjustment assembly, and a positioning assembly 40. A sliding cavity 21 is provided on the frame 20. The adjustment assembly includes a telescopic block 31, a grinding belt 32, an angled component 33, a tensioning component 34, and a driving component 35. One end of the telescopic block 31 is slidably disposed within the sliding cavity 21, and the other end of the telescopic block 31 is rotatably connected to the middle of the angled component 33. The angle of the angled component 33 relative to the telescopic block 31 is adjustable. The tensioning component 34 is rotatably disposed on the frame 20, and the driving component 35 is disposed on the frame 20. The grinding belt 32 is sleeved on the output shaft of the tensioning member 34, the driving member 35 and the two ends of the angle member 33. The tensioning member 34, the driving member 35 and the two ends of the angle member 33 are distributed at the four corners to jointly support the grinding belt 32 in all directions. The driving member 35 is used to drive the grinding belt 32 to rotate. The positioning assembly 40 includes a base 41, a slide 42, a push plate 43 and a push spring 44. The base 41 and the slide 42 are both set on the worktable 10. The push plate 43 is slidably set on the slide 42. The two ends of the push spring 44 abut against the slide 42 and the push plate 43 respectively. The push plate 43 is used to push the magnetic material 50 close to the grinding belt 32.

[0023] It should be noted that a sliding cavity 21 is provided in the middle of the frame 20 along the transverse direction. One end of the telescopic block 31 is adjustablely slidable within the sliding cavity 21, while the other end of the telescopic block 31 extends out relative to the sliding cavity 21. The angular member 33 tends to have an equilateral triangle structure, with its obtuse angle rotatably connected to the end of the telescopic block 31 away from the sliding cavity 21, allowing the two acute angles of the angular member 33 to swing around the telescopic block 31 as the center, and the angle of rotation of the angular member 33 relative to the telescopic block 31 is adjustable. One end of the tensioning member 34 is rotatably connected to the upper end of the frame 20, allowing the tensioning member 34 to swing relative to the frame 20. The driving member 35 is a motor. The structure includes a drive component 35 mounted on the frame 20, positioned below the tensioning component 34, with the tensioning component 34, drive component 35, and the two acute-angled ends of the angled component 33 arranged in a four-corner configuration. Furthermore, the grinding belt 32 is a sanding belt structure, fitted onto the output shafts of the tensioning component 34 and drive component 35, and the two acute-angled ends of the angled component 33. When the telescopic block 31 slides away from the sliding cavity 21 to move the angled component 33 away from the frame 20, and simultaneously the tensioning component 34 rotates away from the angled component 33, the output shafts of the tensioning component 34 and drive component 35, and the two acute-angled ends of the angled component 33 work together to tighten the grinding belt 32 in all directions, resulting in a taut grinding belt 32. For ease of description, viewed from a frontal perspective, the obtuse angle of the angular component 33 is rotatably connected to the end of the telescopic block 31 away from the sliding cavity 21, while the two acute angles of the angular component 33 are both located on the side away from the sliding cavity 21 at the obtuse angle position, and the two acute angle positions are distributed vertically. At this time, the part of the grinding belt 32 passing through the two acute angle positions will be perpendicular to the surface of the worktable 10. When the angle between the angular component 33 and the telescopic block 31 is any angle, the angle between the plane of the part of the grinding belt 32 fitted on the angular component 33 between the two acute angle positions and the surface of the worktable 10 can form any angle. In this way, the magnetic material 50 placed on the surface of the worktable 10 can be ground at any angle, thereby meeting the multi-angle chamfering processing requirements of the magnetic material 50, and thus improving the adaptability and stability of the magnetic material 50 product during assembly.

[0024] It should be noted that the workbench 10 is provided with a first table surface 100 and a second table surface 101. The height of the second table surface 101 is higher than that of the first table surface 100, and is consistent with the height of the telescopic block 31 located on the frame 20. The frame 20 is set on the first table surface 100, and the base 41 is set on the second table surface 101. Furthermore, the positioning component 40 also includes two side blocks 45, which are respectively set on opposite sides of the base 41, and both side blocks 45 are perpendicular to the surface of the grinding belt 32. The two side blocks 45 have an L-shaped structure, so that the two side blocks 45 form two slot structures on both sides of the base 41. The slide 42 includes a horizontal block and two slide rods. The horizontal block is set on the second table surface 101, and one end of each of the two slide rods is set at both ends of the horizontal block, while the other end of each slide rod is fixedly connected to the end face of the base 41 away from the grinding belt 32. The push plate 43 slides on the two slide rods, so that the push plate 43 slides on the two slide rods. Plate 43 can slide relative to the slide rod to approach or move away from the base 41; two push springs 44 are provided, each sleeved on the two slide rods, and the two ends of the two push springs 44 abut against the horizontal block and the push plate 43 respectively, so that the two push springs 44 can push the push plate 43 closer to the base 41 at the same time, thereby allowing the push plate 43 to push the two sides of the magnetic material 50 to slide through the two slots respectively, to prevent the magnetic material 50 from tilting upward and detaching from the base 41 during the grinding process, so that the magnetic material 50 can extend from the end of the base 41 away from the push plate 43 under the limitation of the two slots and abut against the grinding belt 32, so that the grinding belt 32 can perform chamfering on the magnetic material 50.

[0025] like Figures 1 to 2 , Figure 5 As shown, in one embodiment, the angular member 33 includes an angular plate 330 and two angular wheels 331. The middle part of the angular plate 330 is rotatably connected to the telescopic block 31 with adjustable angle. The two angular wheels 331 are respectively rotatably disposed at both ends of the angular plate 330. The two angular wheels 331, together with the tensioning member 34 and the driving member 35, support the grinding belt 32.

[0026] It should be noted that the angle plate 330 tends to have an equilateral triangular structure. The obtuse angle of the angle plate 330 is rotatably connected to the side of the telescopic block 31 away from the sliding cavity 21, while the two corner wheels 331 are rotatably connected to the acute angle of the angle plate 330 respectively. There are two angle plates 330, which together clamp the two corner wheels 331 and the telescopic block 31 to form a triangular double-layer structure, thereby increasing the stability of the angled component 33. Furthermore, the two corner wheels 331 are distributed at the four corners with the tensioning component 34 and the driving component 35 to tighten the grinding belt 32 in all directions.

[0027] like Figures 1 to 2 , Figure 5As shown, in one embodiment, the corner member 33 further includes a corner locking block 332. An arc-shaped hole 3300 is provided on the corner plate 330, and the corner locking block 332 passes through the arc-shaped hole 3300 and is screwed to the telescopic block 31.

[0028] It should be noted that an arc-shaped hole 3300 is provided at the outer obtuse angle position of the angle plate 330; the angle locking block 332 is a hand-tightening nut structure, and the angle locking block 332 passes through the arc-shaped hole 3300 and is screwed onto the telescopic block 31. Thus, when the angle locking block 332 is loosened, the angle plate 330 can rotate to any angle relative to the telescopic block 31; when the angle locking block 332 is tightened, the angle plate 330 cannot rotate relative to the telescopic block 31, thereby fixing the angle of rotation of the angle plate 330 relative to the telescopic block 31. This makes the angle of the portion of the grinding belt 32 located between the two angle wheels 331 adjustable. Specifically, for ease of description, the two corner wheels 331 are defined as the upper corner wheel and the lower corner wheel, respectively. When the straight line connecting the axis of the upper corner wheel and the axis of the lower corner wheel is vertical, the surface of the grinding belt 32 located between the upper and lower corner wheels is perpendicular to the second table 101. When the corner plate 330 rotates counterclockwise relative to the telescopic block 31, the upper corner wheel rotates closer to the top of the second table 101, and the lower corner wheel rotates away from the bottom of the second table 101, so that the surface of the grinding belt 32 located between the upper and lower corner wheels forms an angle with the second table 101. Thus, when the magnetic material 50 is placed on the base 41, the grinding belt 32 can bevel the edges of the magnetic material 50 and can perform processing at various angles.

[0029] like Figures 1 to 2 , Figure 5 As shown, in one embodiment, the angular member 33 further includes a top plate 333, which is disposed on the corner plate 330 and is located between the two corner wheels 331. When the push plate 43 pushes the magnetic material 50 to abut against the grinding belt 32, the grinding belt 32 abuts against the top plate 333.

[0030] It should be noted that the top plate 333 is connected to the side of the two corner plates 330 near the telescopic block 31 on both sides. The length of the top plate 333 is close to the interval between the two corner wheels 331, and the top plate 333 is close to the inner side of the grinding belt 32. Since the grinding belt 32 has a certain tension, when the push plate 43 pushes the magnetic material 50 out of the base 41 and abuts against the outer side of the grinding belt 32, the magnetic material 50 will push the grinding belt 32 in a V-shaped indentation towards the corner plate 330 with the two corner wheels 331 as the fulcrum. Once the contact position between the grinding belt 32 and the magnetic material 50 is V-shaped, the grinding belt 32 will wrap around the end of the magnetic material 50, thus making it impossible to achieve the chamfering process. Therefore, the top plate 333 is located on the side of the grinding belt 32 away from the base 41. When the magnetic material 50 pushes the grinding belt 32, the top plate 333 can push the grinding belt 32 to maintain a flat shape and abut against the magnetic material 50, thereby ensuring the chamfer angle.

[0031] like Figures 1 to 4 As shown, in one embodiment, the tensioning member 34 includes a top wheel 340, a rocker arm 341, a connecting rod 342, a sleeve 343, and a tension spring 345. One end of the rocker arm 341 is rotatably mounted on the frame 20, one end of the connecting rod 342 is rotatably mounted on the rocker arm 341, the sleeve 343 is rotatably mounted on the frame 20, and the sleeve 343 is sleeved with the connecting rod 342. Both ends of the tension spring 345 abut against the connecting rod 342 and the sleeve 343, respectively. The top wheel 340 is rotatably mounted on the rocker arm 341. The top wheel 340, the driving member 35, and the two corner wheels 331 together support the grinding belt 32.

[0032] It should be noted that one end of the swing rod 341 is rotatably mounted on the upper end of the frame 20, one end of the connecting rod 342 is rotatably connected to the end of the swing rod 341 away from the frame 20, and one end of the sleeve 343 is rotatably mounted on the side of the frame 20 near the corner plate 330. The end of the sleeve 343 away from the frame 20 is sleeved with the end of the connecting rod 342 away from the swing rod 341, so that when the swing rod 341 rotates relative to the frame 20, the swing rod 341 drives the connecting rod 342 to slide coaxially within the sleeve 343; further... Furthermore, a locking platform is provided on the end of the connecting rod 342 near the swing rod 341, and a locking platform is also provided on the end of the sleeve 343 near the frame 20. The two ends of the tension spring 345 abut against the two locking platforms respectively, so that the tension spring 345 pushes the connecting rod 342 to drive the swing rod 341 to swing clockwise relative to the frame 20. Further, the top wheel 340 is rotatably disposed in the middle of the swing rod 341, and the circumferential surface of the top wheel 340 protrudes from the side of the swing rod 341 away from the frame 20. Further, a pulley is provided on the output shaft of the drive member 35, and the grinding belt 32 is sleeved on the pulley, the two corner pulleys 331 and the top wheel 340. In this way, the tension spring 345 can push the connecting rod 342, so that the swing rod 341 drives the top wheel 340 to keep pushing the grinding belt 32 upward at all times, thereby keeping the grinding belt 32 under tension. Furthermore, a swing arm 341, a connecting rod 342, a sleeve 343 and a tension spring 345 are respectively provided on both sides of the frame 20, and the two swing arms 341 are rotatably connected to a top wheel 340, so that the top wheel 340 can push the grinding belt 32 more stably.

[0033] like Figures 1 to 3 As shown, in one embodiment, the adjustment assembly further includes a sliding block 36, which is screwed onto the frame 20 and is used to press against the telescopic block 31.

[0034] It should be noted that the frame 20 has a transverse sliding cavity 21, one end of which is open and faces the end of the corner piece 33. Furthermore, the sliding lock block 36 is a hand-tightening nut structure, with one end of the sliding lock block 36 passing through the frame 20 and extending into the sliding cavity 21 to abut against the telescopic block 31. Thus, when the telescopic block 31 causes the corner piece 33 to extend relative to the frame 20 to any position, tightening the sliding lock block 36 secures the telescopic block 31, preventing it from sliding relative to the sliding cavity 21. This allows the position of the telescopic block 31 causing the corner piece 33 to extend relative to the frame 20 to be adjustable.

[0035] It should be noted that, for example, when chamfering is required for long magnetic materials 50 / short magnetic materials 50, the telescopic block 31 can be used to move the angular part 33 away from / near the frame 20, thereby moving the grinding belt 32 closer to / away from the second table surface 101. In this way, chamfering processing of magnetic materials 50 of different lengths can be satisfied.

[0036] like Figures 1 to 4 As shown, in one embodiment, the adjustment assembly further includes a screw 37, which is screwed onto the frame 20, and one end of the screw 37 extends into the sliding cavity 21 and is rotatably connected to the telescopic block 31.

[0037] It should be noted that a handwheel 370 is provided on the end of the screw 37 away from the telescopic block 31, allowing the operator to rotate the handwheel 370 to rotate the screw 37 relative to the frame 20, thereby causing the screw 37 to slide the telescopic block 31 within the slide cavity 21. Furthermore, since the screw 37 and the frame 20 are connected by a screw thread, mechanical clearance is unavoidable. Therefore, when the screw 37 extends the telescopic block 31 relative to the slide cavity 21 to bring the grinding belt 32 into contact with the magnetic material 50, the magnetic material 50 will push the grinding belt 32 back, affecting the chamfering accuracy. Thus, after the screw 37 adjusts the distance between the grinding belt 32 and the second table surface 101 via the telescopic block 31, tightening the sliding lock block 36 to press the telescopic block 31 perpendicularly prevents it from sliding, thus fixing the distance between the grinding belt 32 and the second table surface 101 and improving the chamfering accuracy.

[0038] like Figures 6 to 7 As shown, in one embodiment, the positioning component 40 further includes a limiting rod 46, which is screwed onto the push plate 43. The push spring 44 pushes the push plate 43 close to the base 41 so that the depth of the chamfer of the magnetic material 50 is adjustable.

[0039] It should be noted that the limiting rod 46 is a screw structure and is screwed onto the push plate 43. One end of the limiting rod 46 extends relative to the side of the push plate 43 closest to the base 41. Thus, when the push spring 44 pushes the push plate 43 to move the magnetic material 50 closer to the grinding belt 32, it also moves the limiting rod 46 closer to the base 41. Since the limiting rod 46 extends relative to the side of the push plate 43 closest to the base 41, when the push plate 43 approaches the base 41, the limiting rod 46 abuts against the base 41 first, thus preventing the push plate 43 from approaching the base 41. The limiting rod 46 is screwed onto the push plate 43, making the distance it extends relative to the side of the push plate 43 closest to the base 41 adjustable, thereby making the distance by which the push plate 43 pushes the magnetic material 50 from the other end of the base 41 adjustable. The specific operation is as follows: First, loosen the sliding lock block 36, then rotate the screw 37 to drive the angled part 33 closer to the second table surface 101, and then tighten the sliding lock block 36 to fix the gap between the angled part 33 and the second table surface 101. Then loosen the angle lock block 332 to adjust the angle between the polishing belt 32 and the second table surface 101, and then tighten the angle lock block 332 to fix it. Place the magnetic material 50 on the base 41 and make contact with the push plate 43. In this way, when the operator releases his hand, the push plate 43 pushes the magnetic material 50 through the slot and makes contact with the inclined polishing belt 32. Under the push of the push spring 44, the magnetic material 50 continuously abuts against the grinding belt 32, so that one corner of the magnetic material 50 is gradually ground off by the grinding belt 32. At the same time, when the push spring 44 pushes the limiting rod 46 screwed on the push plate 43 to abut against the base 41, the part of the magnetic material 50 that is ground off by the grinding belt 32 is exactly the depth of chamfering required. Thus, by rotating and adjusting the length of the limiting rod 46 extending relative to the push plate 43, the depth of chamfering of the magnetic material 50 can be adjusted.
