Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core processing, and more specifically, to a device for removing burrs from the surface of a magnetic core. Background Art

[0002] A magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristics of low loss. Nickel-zinc ferrite has extremely high impedance and low magnetic permeability of less than a few hundred. Magnetic cores are mainly used in coils and transformers of various electronic equipment. Common toroidal magnetic cores need to be deburred during the processing process.

[0003] The common deburring process of annular cores on the market is that the burrs of annular cores are generally on the inner and outer surfaces. Therefore, the existing deburring method generally sets up two sets of equipment, one set is used to remove the burrs on the inner ring of the core, and then moves to another set of equipment to remove the burrs on the outer ring of the core. In the process of processing annular cores, the existing equipment is cumbersome to operate, and two sets of equipment and two sets of operators are required for processing, which is inefficient.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a magnetic core surface deburring device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a device for deburring the surface of a magnetic core.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: the magnetic core surface deburring equipment comprises a machine table, a processing hole for placing the magnetic core for deburring is opened at the center position inside the machine table, and a fixed plate is arranged on the top of the machine table, a support plate supporting the motor is horizontally slidably connected inside the fixed plate, and the motor is symmetrically installed on both sides of the top of the support plate, a sleeve for deburring the outer ring of the magnetic core is installed at the power output end of the motor on one side of the top of the support plate, and a grinding roller for deburring the inner ring of the magnetic core is installed at the power output end of the motor on the other side of the top of the support plate.

[0007] In this solution, a linkage shaft is arranged at the center position inside the sleeve and a bearing connected to a pressure ring is installed at the end of the linkage shaft. The end of the linkage shaft is connected to the end of the sleeve outer sleeve. A connecting rod is installed in the inner sleeve of the bearing and a pressure ring is arranged at the end of the connecting rod for fixing the position of the magnetic core to be processed. When deburring the outer ring of the magnetic core, the pressure ring can be attached to the upper surface of the magnetic core to fix the position of the magnetic core. A grinding ring for deburring the outer periphery of the magnetic core is installed on the inner wall of the sleeve end.

[0008] In this embodiment, cylinders are installed on both sides of the machine and the power output ends of the cylinders pass through the interior of the machine and extend to the inside of the processing hole. The power output ends of the cylinders are provided with arc-shaped clamping rings for clamping the outer periphery of the magnetic core to be processed, and the arc-shaped clamping rings are stacked on both sides of the processing hole, so that when the inner ring of the magnetic core is deburred, the arc-shaped clamping rings can fix the position of the magnetic core from the outer periphery of the magnetic core under the action of the cylinder power.

[0009] It should be noted that lifting cylinders are installed at the four corners of the top of the machine and are connected to the fixed plate through the lifting cylinders. The power output end of the lifting cylinder is connected to the bottom of the fixed plate, so that the vertical height adjustment of the fixed plate and the motor assembly can be achieved by controlling the lifting and lowering of the power end of the lifting cylinder.

[0010] Furthermore, both sides of the fixed plate are provided with sliding grooves in the horizontal direction, and both sides of the surface of the support plate are provided with sliding blocks inserted into the sliding grooves, and both ends of the support plate are fixedly connected with end plates for limiting the displacement amplitude of the support plate.

[0011] Wherein, a rubber ring is bonded to the end of the surface of the pressure ring away from the connecting rod and adhered to the upper surface of the magnetic core to fix its position.

[0012] Preferably, a curved rubber pad is bonded to the surface of the curved clamp ring on one side facing the center of the processing hole and is adhered to the outer periphery of the magnetic core through the curved rubber pad.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The processing hole set in the center of the machine is used to place the annular magnetic core to be processed. The support plate can be slid horizontally through the slide groove inside the fixed plate to drive the adjustment of the motor position on the support plate surface. The motor power output end is respectively equipped with a sleeve for deburring the outer ring of the magnetic core and a grinding roller for deburring the inner core of the magnetic core. During the processing operation, the position of the support plate can be adjusted first so that the bottom of the motor on one side of the sleeve is aligned with the processing hole position, and the grinding ring inside the sleeve is used to deburr the corresponding position of the outer ring surface of the magnetic ring. After the outer ring processing is completed, the fixed plate is raised and the support plate is slid along the fixed plate so that the grinding roller at the power end of the motor on the other side is aligned with the processing hole position. The fixed plate is controlled to move down until the grinding roller is inserted into the center of the magnetic ring. The grinding roller can be used to deburr the inner ring of the magnetic ring. Quick switching on the same equipment can meet the deburring operations at different positions of the inner and outer rings of the annular magnetic core, greatly improving the processing efficiency and reducing the processing time.

[0015] 2. The lifting cylinder is used to control the vertical height adjustment of the fixed plate and then drive the height adjustment of the motor power end. When the deburring equipment enters the processing hole, the adjacent deburring equipment on the unworked side simultaneously enters the hole on the side of the processing hole, which does not affect the processing operation. When processing the outer periphery of the annular magnetic core, the sleeve is pressed down until the rubber ring at the bottom of the pressure ring is pressed to the surface of the magnetic core. At this time, the grinding ring is inserted into the outer periphery of the magnetic core. When the sleeve rotates, the grinding ring rotates synchronously to perform deburring processing. The bearing plays a connecting role. At the same time, due to the friction between the pressure ring and the magnetic core, its position can be kept fixed, and the position of the magnetic core is fixed by the pressure ring.

[0016] 3. When deburring the inner ring of the magnetic core, control the operation of the cylinder, and its power end drives the arc clamp ring to move toward the center of the processing hole until the arc rubber pads on the surface of the arc clamp ring fit to the two sides of the surface of the magnetic core. The arc clamp ring and the arc rubber pads can be used to fix the position of the magnetic core, making it convenient for the grinding roller to process the inner ring of the magnetic core.
