Description

Technical Field

[0001] The present invention belongs to the technical field of air-gap opening, and particularly relates to a semi-automatic air-gap opening device for circular magnetic core products and an implementation method thereof. Background Art

[0002] The main reason for the instability of the core inductance is that the initial permeability of the soft ferrite core changes due to environmental influences, and it will be affected by environmental factors such as temperature, humidity, time, etc. When an air gap is opened in the core, the initial permeability of the material drops to the effective permeability, and all instability factors are improved. There are many material grades and complex geometric shapes of ferrite cores. Generally, there is a central column in the core structure, and an air gap can be opened by grinding the central column.

[0003] In a new emerging field, the shape of the magnetic core is circular, and there is a circular ring in the middle that needs to be ground to open an air gap (the shaded part in the attachment Figure 10 ). If the traditional engraving machine is used to complete this processing method, the efficiency is extremely low, which cannot meet the growing mass production demand, and the reference plane used is incorrect, so it is impossible to well guarantee the air-gap accuracy of the product, and the core inductance will also be relatively unstable.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1

[0043] Please refer to Figures 1-11 , the present invention provides the following technical solutions: A semi-automatic air gap opening device for circular magnetic core products, including a table board 1, a grinding mechanism 2 is connected above the table board 1, a grinding wheel 9 is connected to the output end of the grinding mechanism 2, a limiting mechanism 3 corresponding to the grinding wheel 9 is connected to the grinding mechanism 2, a feeding mechanism 4 is arranged on one side of the grinding mechanism 2, a floating mechanism 5 is connected to the slider of the feeding mechanism 4, the product 8 is fixed on the floating mechanism 5, and the grinding mechanism 2, the limiting mechanism 3, the feeding mechanism 4 and the floating mechanism 5 form an air gap opening structure. In this embodiment, two air gap opening structures are installed on the table board 1.

[0044] Furthermore, the grinding mechanism 2 includes a motor base 21 and a motor 22. Among them, the motor base 21 is installed above the table board 1, the motor 22 is connected to the motor base 21, the grinding wheel 9 is connected to the output end of the motor 22, and the motor 22 is of a cylindrical structure.

[0045] By adopting the above technical solutions, the grinding wheel 9 is driven by the motor 22 to rotate, and the product 8 is subjected to grinding and air gap opening operations.

[0046] Furthermore, the limiting mechanism 3 includes a fixture cylinder 31, a retaining ring 32 and a substrate 33. Among them, the fixture cylinder 31 is sleeved on the circumference of the motor 22, and one side of the fixture cylinder 31 away from the motor base 21 is connected to the substrate 33 through the retaining ring 32.

[0047] By adopting the above technical solutions, the feeding depth of the product 8 is limited by the substrate 33, and the relative position between the substrate 33 and the grinding wheel 9 is adjusted, so that the depth of the air gap can be controlled.

[0048] Furthermore, the feeding mechanism 4 includes a rodless cylinder 41 and a speed stabilizer 42. Among them, the rodless cylinder 41 and the speed stabilizer 42 are respectively fixed above the table board 1, and the speed stabilizer 42 is located on one side of the rodless cylinder 41.

[0049] By adopting the above technical solutions, the rodless cylinder 41 provides power for the feeding of the product 8, and the speed stabilizer 42 slows down the feeding speed.

[0050] Further, the floating mechanism 5 includes a floating mechanism mounting seat 51, a middle turntable 53, a coupling 54, and a product mounting plate 55. Among them, the floating mechanism mounting seat 51 is fixed on the slider of the rodless cylinder 41. One side of the floating mechanism mounting seat 51 is connected to the middle turntable 53. The product mounting plate 55 is connected to the middle turntable 53 through the coupling 54. The product mounting plate 55 is a magnetic component, and a limiting block 59 is connected to the product mounting plate 55.

The limiting block 59 is stuck in the notch of the product 8, which can prevent the product 8 from rotating together with the grinding wheel 9 during grinding.

[0052] Further, a buffer baffle 52 corresponding to the speed stabilizer 42 is connected to one side of the floating mechanism mounting seat 51 away from the speed stabilizer 42.

[0053] By adopting the above technical solution, the speed stabilizer 42 is triggered by the buffer baffle 52. When the buffer baffle 52 touches the end of the speed stabilizer 42, the advancing speed of the rodless cylinder 41 can be made very slow.

[0056] Further, the implementation method of the semi-automatic air gap opening device for the circular magnetic core product of the present invention includes the following steps:

[0057] (1). During use, adjust the position of the fixture cylinder 31, and then place the product 8 inside the product mounting plate 55, so that the notch on the product 8 is stuck on the limiting block 59, and the product 8 and the product mounting plate 55 are magnetically adsorbed and fixed;

[0058] (2). During operation, the motor 22 drives the grinding wheel 9 to rotate, and the rodless cylinder 41 drives the floating mechanism 5 to quickly move towards the side of the grinding mechanism 2. When the buffer baffle 52 contacts the end of the speed stabilizer 42, the feeding speed of the floating mechanism 5 is slowed down;

[0059] (3). When the product 8 contacts the grinding wheel 9, the grinding wheel 9 grinds the product 8 to open the air gap. At this time, under the action of the contact between the product 8 and the grinding wheel 9, the spring 57 will be compressed for buffering. After grinding in place, the rodless cylinder 41 retracts;

[0060] (4). The substrate 33 limits the feeding depth of the product 8, and by adjusting the relative position between the substrate 33 and the grinding wheel 9, the adjustment of the opening air gap depth is achieved;

[0061] (5). The shield 6 prevents the sewage generated during grinding from splashing outwards, and the sewage guide plate 7 discharges the sewage outside the device.

[0062] In this embodiment, the model of the motor 22 is SQD80 - 0.8C - 40K, sold by Zhenyu Machinery Co., Ltd.; the model of the rodless cylinder 41 is RMT25X150S, sold by AirTAC (China) Co., Ltd.; the model of the speed stabilizer 42 is HR15, sold by Taiwan Seiko Co., Ltd.; the model of the coupling 54 is φ44*50, sold by Huazhen Machinery Co., Ltd.

[0063] Embodiment 2

[0064] The difference between this embodiment and Embodiment 1 is that: further, a shield 6 is connected above the platen 1 corresponding to the position of the limiting mechanism 3, a sewage guide plate 7 corresponding to the shield 6 is connected to the bottom of the platen 1, and the bottom of the shield 6 is communicated with the sewage guide plate 7.

[0065] By adopting the above technical solution, the shield 6 can prevent the water used for cooling and lubrication from splashing out during the grinding process, and the sewage guide plate 7 can discharge the sewage outside the device.
