Description

Technical Field

[0001] The utility model relates to the technical field of iron core grinding, in particular to a microcrystalline iron core grinding device. Background Art

[0002] Microcrystalline iron core is a magnetic material composed of microcrystalline grains with high magnetic permeability and good soft magnetic properties. In electrical equipment, microcrystalline iron core is often used as the core material of transformers, inductors and electromagnets because it can provide higher magnetic flux density and energy efficiency at a lower material cost. Microcrystalline iron core grinding device is a professional equipment used for grinding microcrystalline iron cores. It is suitable for industries such as electricity and electronics. This device processes microcrystalline iron cores through a high-speed rotating grinding head, improving their surface finish and dimensional accuracy, making the product performance more stable.

[0003] A Chinese patent provides an ultra-fine crystal iron core grinding device with a recovery structure, with publication number CN218488109U, comprising an installation box, a grinding motor installed above the installation box, a grinding disc connected to the output end of the grinding motor, an installation shell installed on the lower surface inside the installation box, an exhaust fan placed on the right side of the installation box, a mounting plate provided at the front end of the installation shell, a filter baffle placed inside the installation plate, connecting blocks provided at both ends of the installation plate, and a feed port connected to the upper end of the installation box.

[0004] The above-mentioned device is equipped with an exhaust fan, which, in cooperation with the feed port, enables the exhaust fan to draw the powder generated during grinding into the installation shell and collect the powder. However, when the device is in use, when the grinding disc grinds the microcrystalline iron core, the contact surface between the two will generate extremely high temperature. The accumulation of a large amount of heat will cause thermal deformation of the microcrystalline iron core, and tiny abrasive particles will adhere to the surface of the iron core. Utility Model Content

[0005] The main purpose of the present invention is to provide a microcrystalline iron core grinding device, which can effectively solve the technical problem in the background technology that the contact surface between the grinding wheel and the microcrystalline iron core will generate extremely high temperature, and a large amount of heat will accumulate, causing thermal deformation of the microcrystalline iron core.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A microcrystalline iron core grinding device includes a collecting cylinder, a positioning block is fixedly installed at the rear part of the collecting cylinder, a cross limit block is provided on the inner wall of the positioning block, a fixing cylinder is fixedly installed on the top of the cross limit block, sliding grooves are provided on the left and right outer walls of the cross limit block, sliding blocks are slidably connected to the inner walls of the two sliding grooves, and connecting blocks are fixedly installed at the far ends of the two sliding blocks.

[0008] As a further solution of the present invention, the adjacent surfaces of the two connecting blocks are rotatably connected with connecting shafts, the adjacent ends of the two connecting shafts are fixedly installed with support frames, the four corners of the support frames are threadedly connected with screws, and one end of the screw is fixedly installed with an extrusion block.

[0009] As a further solution of the present invention, a water tank is fixedly installed on the top of the fixed cylinder, a connecting pipe is fixedly installed on one side outer wall of the water tank, and a connecting ring is fixedly installed on one end of the connecting pipe.

[0010] As a further solution of the present invention, four nozzles are fixedly mounted on the inner wall of the connecting ring, and the nozzles penetrate the outer wall of the fixed cylinder near the bottom.

[0011] As a further solution of the present invention, a hydraulic rod is fixedly mounted on the inner wall of the fixed cylinder, a motor is fixedly mounted on the output end of the hydraulic rod, and a grinding disc is fixedly mounted on the output end of the motor.

[0012] As a further solution of the present invention, two small fans are fixedly mounted on the outer wall of the collecting tube, and air outlet pipes are fixedly mounted on adjacent surfaces of the two small fans, and the air outlet pipes pass through the outer wall of the collecting tube near the top.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1) During the grinding process, the nozzle of the microcrystalline iron core grinding device sprays coolant onto the surface of the grinding disc and the microcrystalline iron core, which helps to reduce the temperature, reduce heat accumulation, reduce thermal deformation of the microcrystalline iron core, and avoid affecting the size and precision of the iron core. In addition, the wind generated by the small fan is blown to the bottom of the microcrystalline iron core through the air outlet pipe. While being able to cool down, it removes tiny abrasive particles attached to the surface of the iron core, which affects subsequent processing and performance and falls into the collection tube.

[0015] 2) The microcrystalline iron core grinding device, after grinding one side of the microcrystalline iron core, moves the fixed cylinder upward. During the movement, the clamping part will gradually move to the bottom of the cross limit block. At this time, the support frame can be flipped over to swap the position of the ground side with the unground side. After swapping the positions, the cross limit block is reset and grinding is performed again. The staff does not need to remove the installed and fixed microcrystalline iron core to grind both sides of the microcrystalline iron core, and the grinding process is in a relatively closed state. The dust and debris generated by the grinding are not easy to fly out and affect the staff. BRIEF DESCRIPTION OF THE DRAWINGS
