Technical Field

[0001] The invention relates to the technical field of soft magnetic body processing, in particular to a soft magnetic body grinding and turning device. Background Art

[0002] Soft magnetic materials are easy to be magnetized, and after being magnetized, the magnetism is easy to disappear. They are also easy to demagnetize by knocking and heating. They are widely used in electrical equipment and electronic equipment (such as electromagnetic cranes). The most widely used soft magnetic material is iron silicon alloy (silicon steel sheet), which is used in electromagnets, electromagnetic relays, transformers and motor cores, as well as various soft ferrites. With the continuous advancement of science and technology, the demand for soft ferrite materials is also increasing, and the performance requirements are also constantly improving.

[0003] In the grinding process of soft ferrite cores, most of them require grinding the bottom of the soft ferrite core. The existing processing technology usually requires grinding the bottom first and then grinding the surface, and turning the surface with a customized stainless steel plate in the middle. After turning it over, it needs to be clamped again, which is inefficient and inconvenient to use. Therefore, a soft magnetic grinding and turning device with high working efficiency and easy use is needed. Summary of the invention

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] like Figure 1 As shown, a soft magnetic body grinding and turning device comprises a grinding platform 2, which is arranged on a grinding machine 1. A motor 15 is installed on the top of the grinding machine 1, and a first pulley 16 is installed on the movable shaft end of the motor 15. A gearbox 19 is also provided on the grinding machine 1, and a second pulley 18 is provided on the gearbox 19. A belt 17 is connected between the first pulley 16 and the second pulley 18. A grinding head 14 is installed on the output end of the gearbox 19, and the motor 15 rotates the grinding head 14 through the belt 17, the pulley and the gearbox 19.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, brackets 8 are provided on both sides of the grinding platform 2, and the brackets 8 maintain a certain horizontal distance from the grinding platform 2. Hydraulic cylinders 4 and racks 9 are installed on the two brackets 8. Hydraulic cylinder support seat 3 and hydraulic cylinder stabilizing frame 13 are fixed on the bracket 8. The hydraulic cylinder 4 is fixed on the hydraulic cylinder support seat 3. The hydraulic cylinder stabilizing frame 13 is used to stabilize the hydraulic cylinder 4 so that it is fixed more firmly. The movable axis of the hydraulic cylinder 4 is parallel to the rack 9. Cylinder fixing plates 7 are also provided on both sides of the grinding platform 2. Cylinders 11 are installed on the cylinder fixing plates 7. Clamps 12 are installed on the movable axis of the cylinder 11. Clamps 12 are provided with notches, which are suitable for clamping the soft magnetic body 10 to be polished. Clamps 12 and cylinders 11 are both installed in the center. Rubber pads are fixed on clamps 12, which are suitable for buffering impact force and increasing friction. The notch of clamps 12 is located in the middle of clamps 12. A gear shaft 6 is welded and fixed on one side of the cylinder fixing plate 7 away from the cylinder 11, and a gear 5 is embedded on the outside of the gear shaft 6. A key 22 is arranged on the outside of the gear shaft 6, and a key slot 23 is arranged inside the gear 5, and the key 22 is embedded inside the key slot 23. When the gear 5 rotates, the gear shaft 6 and the cylinder fixing plate 7 are driven to rotate, and at the same time, the cylinder fixing plate 7 drives the cylinder 11 and the soft magnetic body 10 to be polished to flip. The gear 5 is meshed with the rack 9, and the gear shaft 6 is hinged to the movable shaft end of the hydraulic cylinder 4. Specifically, an annular groove 20 is arranged on the outside of the gear shaft 6, and a collar 21 is embedded inside the annular groove 20. The collar 21 is radially movably connected with the annular groove 20, and the movable shaft end of the hydraulic cylinder 4 is fixed to the collar 21. The stroke of the hydraulic cylinder 4 is half of the circumference of the gear 5, which is suitable for the gear 5 to rotate 180° when the movable shaft of the hydraulic cylinder 4 is fully extended.

[0022] like Figure 1 , Figure 2 , Figure 3As shown, when the movable shaft of the hydraulic cylinder 4 is fully retracted, the cylinder fixing plate 7 is placed horizontally on the grinding platform 2. When the movable shafts of the two hydraulic cylinders 4 are synchronously extended outward, the gear 5 is pushed to move to the left. Since the rack 9 is meshed with the gear 5, the gear 5 rotates clockwise while moving to the left. While the gear 5 rotates, it drives the gear shaft 6, the cylinder fixing plate 7, the cylinder 11, and the soft magnetic body 10 to be grinded to flip. The hydraulic cylinder is used here instead of the air cylinder mainly because the extension speed of the movable shaft of the cylinder is difficult to control, and the extension speed of the movable shaft of the hydraulic cylinder can be adjusted to a slower speed, so that the soft magnetic body 10 to be grinded slowly flips. Since the stroke of the hydraulic cylinder 4 is half the circumference of the gear 5, when the movable shaft of the hydraulic cylinder 4 is fully extended, the gear 5 rotates half a circle, which is 180°, and the soft magnetic body 10 to be grinded is completely flipped. The distance between the fixed point of the gear shaft 6 and the fixed plate 7 and the midpoint perpendicular line of the fixed plate 7 is one-fourth of the circumference of the gear 5, that is, when the gear shaft 6 moves to the midpoint perpendicular line of the fixed plate 7 when it is placed horizontally, the gear 5 rotates 90 degrees, and the fixed plate 7 is perpendicular to the horizontal plane. When the movable shaft of the hydraulic cylinder 4 is fully extended, the gear 5 rotates 180 degrees, and the left and right positions of the fixed plate 7 and the soft magnetic body 10 to be polished remain unchanged when the soft magnetic body 10 to be polished is turned over. There is no need to readjust the position of the grinding head 14, nor is there any need to re-clamp. The grinding efficiency is improved.

[0023] When using the soft magnetic body grinding and turning device, after the grinding head 14 finishes processing one side, the grinding head 14 rises, and the movable shaft of the hydraulic cylinder 4 extends outward synchronously, pushing the gear 5 to move to the left. Since the rack 9 is meshed with the gear 5, the gear 5 rotates clockwise while moving to the left. The gear 5 rotates while driving the gear shaft 6, the cylinder fixed plate 7, the cylinder 11, and the soft magnetic body 10 to be ground to turn over. When the movable shaft of the hydraulic cylinder 4 is fully extended, the gear 5 rotates 180°, and the left and right positions of the fixed plate 7 and the soft magnetic body 10 to be ground remain unchanged when the soft magnetic body 10 to be ground completes the turning. At this time, there is no need to readjust the position of the grinding head 14 or to re-clamp it. The grinding head 14 descends and starts to grind the other side, thereby improving the grinding efficiency. The soft magnetic body grinding and turning device has high working efficiency and is easy to use.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
