Description

Technical Field

[0001] This utility model relates to the field of magnetic steel processing equipment, specifically a double-sided edge grinding device for magnetic steel. Background Technology

[0002] Magnets are generally used in motors. Magnets are square in shape and have a certain curvature. Before being installed in the motor, magnets need to be processed. One of the processing steps is to grind the edges and corners to make them chamfered.

[0003] Cylindrical magnets are required in precision motors and sensors. During the production of cylindrical magnets, both ends of the magnets need to be ground. Burrs on the ends of the cylindrical magnets will cause uneven magnetic field distribution, resulting in poor magnetic field perpendicularity when used in precision motors and sensors. To address this, we propose a double-sided edge grinding device for magnets. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a double-sided edge grinding device for magnets, including a base plate 1 and a magnet body 5. A C-shaped plate 2 is fixedly installed in the middle of the upper end of the base plate 1. A magnet clamping and rotating mechanism 3 is provided in the middle of the lower end of the C-shaped plate 2. Movable grinding mechanisms 4 are provided on both sides of the inner end of the C-shaped plate 2. The magnet clamping and rotating mechanism 3 includes a rotating ring 31. Multiple sets of circumferentially distributed magnet clamping components 33 are provided on the inner wall of the rotating ring 31. The magnet clamping components 33 are used to perform circumferential clamping action on magnet bodies 5 with different outer diameters. The magnet clamping and rotating mechanism 3 is used to perform direct rotation action on the magnet body 5. The movable grinding mechanism 4 is used to perform grinding action on both ends of the magnet body 5.

[0022] In this embodiment, the magnetic clamping and rotating mechanism 3 also includes a stepper motor 36. The C-shaped plate 2 is fixedly installed at one end of the stepper motor 36 near the C-shaped plate 2. A rotating shaft 37 is fixedly installed at the output end of the stepper motor 36. A small gear 38 is fixedly installed at the middle of the outer end of the rotating shaft 37. An external gear ring 39 is meshed with the upper end of the small gear 38. A rotating ring 31 is fixedly installed on the surface of the external gear ring 39 and the rotating ring 31 passes through the external gear ring 39. Annular grooves 32 are provided on both sides of the rotating ring 31.

[0023] Specifically, when it is necessary to rotate the clamped magnet body 5, the stepper motor 36 can be started. The output of the stepper motor 36 drives the rotating shaft 37 to rotate. The rotating shaft 37 drives the pinion 38 to rotate. The pinion 38 drives the external gear ring 39 to rotate. The external gear ring 39 drives the rotating ring 31 to rotate. The rotating ring 31 drives the multiple magnet clamping components 33 and the magnet body 5 to rotate directly.

[0024] In this embodiment, the movable grinding mechanism 4 includes an L-shaped fixed plate 41. Two L-shaped fixed plates 41 are fixedly mounted with a second electric push rod 42 at one end close to each other. A grinding plate 43 is fixedly mounted at the output end of the second electric push rod 42.

[0025] Specifically, the second electric push rod 42 can be started by moving the grinding mechanism 4. At this time, the grinding plate 43 at the output end of the second electric push rod 42 moves towards the magnet body 5. When the inner end of the grinding plate 43 comes into contact with the outer end of the magnet body 5, the power supply to the second electric push rod 42 can be stopped.

[0026] In this embodiment, the magnetic clamping assembly 33 includes a first electric push rod 331, and a clamping arc plate 332 is fixedly installed at the output end of each first electric push rod 331.

[0027] Specifically, the first electric push rod 331 can be activated by the magnetic steel clamping assembly 33. At this time, the output end of the first electric push rod 331 drives the clamping arc plate 332 to move inward, and the inner wall of the multiple clamping arc plates 332 abuts against the outer end of the cylindrical magnet.

[0028] In this embodiment, each annular groove 32 is slidably connected to a guide post 34 on its inner wall. Each of the two guide posts 34 is fixedly installed with a contact strip 35 at one end away from each other. A C-shaped plate 2 is fixedly installed on the upper end of the contact strip 35.

[0029] Specifically, during the rotation of the rotating ring 31, the guide post 34 slides within the ring groove 32.

[0030] In this embodiment, the outer end of the rotating shaft 37 passes through the right side of the C-shaped plate 2, and the end of the rotating shaft 37 away from the stepper motor 36 is rotatably connected to the C-shaped plate 2 through a bearing.

[0031] Specifically, ensure that the rotating shaft 37 does not interfere with the C-shaped plate 2 during rotation.

[0032] In this embodiment, multiple sets of magnetic clamping assemblies 33 abut against the magnetic body 5, and two grinding plates 43 abut against the magnetic body 5 at one end.

[0033] Specifically, this ensures that the grinding plate 43 can smoothly perform the grinding action on the end face of the magnet body 5.

[0034] Working principle: First, multiple sets of magnet clamping assemblies 33 clamp magnet bodies 5 of different outer diameters in a centered manner. At this time, the first electric push rod 331 can be activated. The output end of the first electric push rod 331 drives the clamping arc plate 332 to move inward. The inner walls of the multiple clamping arc plates 332 abut against the outer ends of the cylindrical magnets. Next, the second electric push rod 42 is activated. At this time, the grinding plate 43 at the output end of the second electric push rod 42 moves towards the magnet body 5. When the grinding plate 43 moves inward... After the end of the magnet body 5 comes into contact with the outer end, the power supply to the second electric push rod 42 can be stopped. Finally, the stepper motor 36 is started. At this time, the output end of the stepper motor 36 drives the rotating shaft 37 to rotate. At this time, the rotating shaft 37 drives the pinion 38 to rotate. At this time, the pinion 38 drives the outer gear ring 39 to rotate. At this time, the outer gear ring 39 drives the rotating ring 31 to rotate. At this time, the rotating ring 31 drives the multiple magnet clamping components 33 and the magnet body 5 to rotate directly.
