Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core production, and more specifically, to a magnetic core processing fixture. Background Art

[0002] A magnetic core is a sintered magnetic metal oxide composed of a mixture of various iron oxides. Ferrite cores are used in coils and transformers of various electronic devices. During the processing of the magnetic core, a fixing fixture is often required to fix the magnetic core for subsequent processing.

[0003] Common core clamps are mostly composed of a whole platform and clamping blocks driven by lead screws at both ends. When in use, the lead screws are turned to make the clamping blocks move closer to the middle to clamp and fix the core. When using a grinder to grind smaller mini cores, they are usually arranged in multiple rows and columns and grinded together to improve grinding efficiency, so that the grinder can grind multiple cores arranged in a column in a single run.

[0004] However, in actual use, the clamps clamp from both sides, and the clamping force is transmitted from the outside to the inside. The magnetic cores distributed at the outer edge of the array are subject to a larger clamping force, while the magnetic cores distributed inside the array are subject to a smaller clamping force. The clamping force is unevenly distributed. Therefore, the adjustment of the clamping tightness depends on the proficiency of the workers. In addition, the arrangement of multiple cores requires the operator to place the cores one by one and then manually align them row by row, which increases the time for deployment and placement before clamping the cores.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a magnetic core processing fixture. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a magnetic core processing fixture.

[0008] Preferably, sliding columns are provided at both ends of the partition, and the sliding columns are movably inserted into adjustment slots provided on the adjustment frame, and a limit plate is provided at the outer end of the sliding column.

[0009] Preferably, both ends of the connecting plate are slidably connected in the sliding column, and the top of the limiting plate is provided with a plug hole for the lifting rod to extend out of the limiting plate to connect with the pull ring outside.

[0010] Preferably, the height of the strong magnetic sheet is equal to the distance from the inner wall of the slide post to the bottom of the partition, so that when the strong magnetic sheet is adsorbed on the surface of the moving platform, the connecting plate can press the slide post downward to fix the partition.

[0011] Preferably, a buckle plate is buckled at the end of the adjustment frame to facilitate opening the adjustment slot to increase or decrease the number of partitions.

[0012] Preferably, the adjustment frame is bonded and fixed with a strong magnetic column through an embedded groove opened at the bottom, and the strong magnetic column has strong magnetism and can be adsorbed and fixed on the surface of the moving platform.

[0013] Preferably, the outer diameter of the limiting plate is larger than the inner diameter of the adjusting groove to prevent the sliding column from falling off the adjusting groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, a plurality of partitions with strong magnetic sheets installed inside are arranged on the movable table of the grinder and inserted into the magnetic core array at intervals, so that the partitions can be flexibly moved and adjusted on the movable table, and the spacing can be adjusted according to the size of the magnetic core to balance the clamping force inside and outside the magnetic core array. It does not need to rely on the proficiency of the workers, which improves the speed of using the device.

[0016] 2.

In addition, the partition can be pushed to align each column of the magnetic core distribution without manual alignment one by one, which reduces the time for deploying and placing the magnetic core before clamping.

[0024] like Figure 1-5 As shown, a magnetic core processing fixture comprises a movable table 1 for movable grinding on a grinding bed and a partition 2 for arranging the magnetic cores and achieving a clamping effect. A strong magnetic column 10 is bonded and fixed to an adjustment frame 8 through an embedded groove 9 opened at the bottom. The strong magnetic column 10 has strong magnetism and can be adsorbed and fixed on the surface of the movable table 1.

[0025] Determine the distance between the adjustment frames 8 at both ends according to the length of the magnetic core queue, and place the strong magnetic column 10 of the adjustment frame 8 downward on the mobile platform 1. The magnetic core force of the strong magnetic column 10 will firmly fix the adjustment frame 8 on the mobile platform 1.

[0026] The end of the adjustment frame 8 is buckled with a buckle plate 11, which is convenient for opening the adjustment slot 7 to increase or decrease the number of the partitions 2;

[0027] Open the pinch plate 11, add a partition plate 2 by inserting the sliding posts 5 at both ends into the adjustment frame 8, and place the magnetic core to be ground in the space surrounded by the two adjustment frames 8 and the partition plate 2;

[0028] The partition 2 is a hollow shell structure with an opening downward, and a strong magnetic sheet 4 is slidably connected inside the partition 2. The strong magnetic sheet 4 has strong magnetism and can be adsorbed and fixed on the surface of the moving platform 1. A connecting plate 3 is arranged on the side of the strong magnetic sheet 4 away from the moving platform 1. A pull ring 13 is arranged on the surface of the connecting plate 3 through a lifting rod 12 for pulling the strong magnetic sheet 4 up;

[0029] Both ends of the partition 2 are provided with sliding posts 5, which are movably inserted into the adjustment slots 7 provided on the adjustment frame 8, and a limit plate 6 is provided at the outer end of the sliding post 5;

[0030] The two ends of the connecting plate 3 are slidably connected in the sliding column 5, and the top of the limiting plate 6 is provided with a plug hole 14 for the lifting rod 12 to extend out of the limiting plate 6 to connect the pull ring 13;

[0031] Pull the pull rings 13 at both ends upward, the pull rings 13 pull the connecting plate 3 through the lifting rings 13, and the connecting plate 3 drives the strong magnetic sheet 4 to rise. At this time, the bottom of the strong magnetic sheet 4 is at a certain distance from the bottom of the partition 2, so that the strong magnetic sheet 4 leaves the adsorption range of the mobile platform, so that the partition 2 can be easily driven to move on the mobile platform 1;

[0032] The partition 2 is pushed to move toward the previous partition 2. During the process, the adjustment frame 8 fixes the previous partition 2 from both ends. Both ends of the pushed partition 2 are limited by the adjustment frame 8 to keep it moving straight forward. The magnetic core queue is pushed to align. Pushing the partition 2 can align each column of the magnetic core distribution without manual alignment one by one, which reduces the time for deployment and placement of the magnetic core clamping.

[0033] The outer diameter of the limit plate 6 is larger than the inner diameter of the adjustment groove 7 to prevent the slide column 5 from falling off the adjustment groove 7;

[0034] When the partition 2 can no longer be pushed forward, the pull ring 13 is released, and the strong magnetic sheet 4 falls down and is adsorbed on the moving platform 1 by magnetic attraction, so that the partition 2 is fixed on the moving platform 1, and the partitions 2 on both sides clamp the magnetic core;

[0035] The height of the strong magnetic sheet 4 is equal to the distance from the inner wall of the slide post 5 to the bottom of the partition 2, so that when the strong magnetic sheet 4 is adsorbed on the surface of the moving platform 1, the connecting plate 3 can press the slide post 5 downward to fix the partition 2;

[0036] By analogy, the number of baffles 2 is continuously added to the adjustment frame 8, and finally the effect of aligning the magnetic core queues in rows and clamping them from both sides is achieved. The baffles 2 arranged at intervals in the magnetic core queues evenly disperse the clamping force, and the clamping action can be easily completed without relying on the proficiency of the operator;

[0037] Therefore, a plurality of partitions 2 with strong magnetic sheets 4 installed inside are arranged on the movable table 1 of the grinder, and are inserted in the magnetic core array at intervals, so that the partitions 2 can be flexibly moved and adjusted in position on the movable table 1, and the spacing can be adjusted according to the size of the magnetic cores to balance the clamping force inside and outside the magnetic core array. This does not need to rely on the proficiency of the workers in operation, thereby improving the speed of getting started with the device.

[0038] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
