Description

Technical Field

[0001] This utility model relates to the technical field of magnetic grinding devices, and in particular to a magnetic grinding device. Background Technology

[0002] A magnetic abrasive device is a device used to polish workpieces. It uses a magnetic field to carry the polishing needle and the workpiece in a container at a high frequency of rotation. The polishing needle polishes the workpiece to remove burrs and dirt.

[0003] Existing magnetic grinding devices can only drive the grinding needle to rotate, and the tumbling and throwing generated when the grinding needle moves is minimal, resulting in low grinding efficiency.

[0004] Existing magnetic grinding devices do not have the function of recycling grinding needles. After use, the grinding needles in the container need to be manually removed for recycling, which is cumbersome. Utility Model Content

[0005] The purpose of this invention is to solve the problems of insufficient tumbling and throwing of the grinding needle during the movement of the grinding needle in the existing magnetic grinding device, and the inconvenience of grinding needle retrieval, and to propose a magnetic grinding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A magnetic grinding device includes a housing, an industrial computer, and a collection basket. The housing includes an inner support plate. A mounting base is fixedly installed at the center of the housing. A limit ring is provided on one side of the mounting base. The bottom of the limit ring is fixedly connected to the surface of the housing. A container is inserted into the limit ring. A magnetic field generating component is provided inside the housing corresponding to the limit ring. A recycling component is provided inside the mounting base. The collection basket is placed on the surface of the housing corresponding to the recycling component. The industrial computer is fixedly installed on one side of the surface of the housing.

[0008] Preferably, the magnetic field generating component includes a partition plate with a through hole in the center. The bottom of the partition plate is fixedly connected to the surface of the inner support plate. A conductive slip ring is fixedly connected to the surface of the partition plate. A turntable is provided on the top of the conductive slip ring. Multiple bar electromagnets are fixedly connected to the surface of the turntable. A rotating rod is fixedly connected to the bottom of the turntable. The bottom of the rotating rod passes through the conductive slip ring, the partition plate, and the inner support plate and is rotatably connected to a stirring motor.

[0009] Preferably, the input end of the conductive slip ring is electrically connected to the industrial control computer, and the output end of the conductive slip ring passes through the turntable and is electrically connected to the bar electromagnet.

[0010] Preferably, the bar electromagnet is symmetrical about the center of the turntable.

[0011] Preferably, the recycling assembly includes a bearing and a rotating motor. The bearing is located inside the mounting base and is rotatably connected to a rotating shaft. A gear ring is fixedly connected to the outer wall of the rotating shaft. A mounting plate is fixedly connected to the top of the rotating shaft. An electric pusher cylinder is fixedly connected to the top of one end of the mounting plate. A cylindrical electromagnet is fixedly connected to the output end of the electric pusher cylinder through the mounting plate.

[0012] Preferably, the rotating motor is located on one side of the rotating shaft, and the output end of the rotating motor is rotatably connected to a drive gear, which meshes with a gear ring.

[0013] Preferably, the input terminals of the rotary motor, electric push cylinder, and cylindrical electromagnet are electrically connected to the industrial control computer.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Under the combined action of the magnetic field generating component and the recovery component, during grinding, the electric pusher cylinder extends and drives the cylindrical electromagnet to descend until it enters the container. The industrial control computer energizes the bar electromagnet to generate a magnetic field, which drives the turntable and the bar electromagnet to rotate through the stirring motor. The bar electromagnet drives the grinding needles in the container to rotate. At this time, the cylindrical electromagnet is intermittently energized. The magnetic force of the cylindrical electromagnet attracts the grinding needles during their rotation, making the movement of the grinding needles more complex and increasing the tumbling and throwing of the grinding needles, thereby improving the grinding efficiency.

[0016] 2. This utility model, by setting up a recycling component, uses an industrial control computer to simultaneously de-energize the bar electromagnet and increase the current flowing to the cylindrical electromagnet. The grinding needle is attracted to the outer wall of the cylindrical electromagnet by magnetic force. After attraction, the electric push rod retracts, causing the cylindrical electromagnet to carry the grinding needle away. A rotating motor drives the rotating shaft to rotate, which in turn moves the mounting plate and the cylindrical electromagnet to above the collection basket. After the electric push rod extends, the power to the cylindrical electromagnet is de-energized by the industrial control computer. At this time, the grinding needle falls into the collection basket under the action of gravity, thus realizing the function of automatically recycling the grinding needle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4 A magnetic grinding device includes a housing 1, an industrial control computer 2, and a collection basket 3. The housing 1 includes an inner support plate 4. A mounting base 5 is fixedly installed at the center of the housing 1. A limit ring 6 is provided on one side of the mounting base 5. The bottom of the limit ring 6 is fixedly connected to the surface of the housing 1. A container 7 is inserted into the limit ring 6. A magnetic field generating component is provided inside the housing 1 corresponding to the limit ring 6. A recycling component is provided inside the mounting base 5. The collection basket 3 is placed on the surface of the housing 1 corresponding to the recycling component. The industrial control computer 2 is fixedly installed on one side of the surface of the housing 1.

[0024] It should be noted that before use, the workpiece to be ground, the grinding needle, and the additives need to be placed in the container 7.

[0025] Furthermore, the magnetic field generating component includes a partition 8, with a through hole 9 at the center of the partition 8. The bottom of the partition 8 is fixedly connected to the surface of the inner support plate 4. A conductive slip ring 10 is fixedly connected to the surface of the partition 8. A turntable 11 is provided on the top of the conductive slip ring 10. Multiple bar electromagnets 12 are fixedly connected to the surface of the turntable 11. A rotating rod 13 is fixedly connected to the bottom of the turntable 11. The bottom of the rotating rod 13 passes through the conductive slip ring 10, the partition 8, and the inner support plate 4 and is rotatably connected to a stirring motor 14. The input end of the conductive slip ring 10 is electrically connected to the industrial control computer 2. The output end of the conductive slip ring 10 passes through the turntable 11 and is electrically connected to the bar electromagnets 12. The bar electromagnets 12 rotate symmetrically around the center of the turntable 11.

[0026] A further advantage of the above is that by setting the conductive slip ring 10, the bar electromagnet 12 can be energized during rotation, thereby stopping the bar electromagnet 12 from adsorbing the grinding needle when the work is finished, so as to support the operation of the recycling component.

[0027] Furthermore, the recycling assembly includes a bearing 15 and a rotating motor 16. The bearing 15 is located inside the mounting base 5 and is rotatably connected to a rotating shaft 17. A gear ring 18 is fixedly connected to the outer wall of the rotating shaft 17, and a mounting plate 19 is fixedly connected to the top of the rotating shaft 17. An electric pusher cylinder 20 is fixedly connected to the top of one end of the mounting plate 19. A cylindrical electromagnet 21 is fixedly connected to the output end of the electric pusher cylinder 20 through the mounting plate 19. The rotating motor 16 is located on one side of the rotating shaft 17, and a drive gear 22 is rotatably connected to the output end of the rotating motor 16. The drive gear 22 meshes with the gear ring 18. The input ends of the rotating motor 16, the electric pusher cylinder 20, and the cylindrical electromagnet 21 are electrically connected to the industrial control computer 2.

[0028] The further advantage of the above is that, during grinding, the industrial control computer 2 intermittently energizes the cylindrical electromagnet 21. The magnetic force of the cylindrical electromagnet 21 attracts the grinding needle during its rotation, making the movement of the grinding needle more complex. After grinding is completed, the cylindrical electromagnet 21 attracts the grinding needle. After attraction, the electric push rod retracts, causing the cylindrical electromagnet 21 to carry the grinding needle away. The rotating motor 16 drives the cylindrical electromagnet 21 to rotate above the collection basket 3, and then the industrial control computer 2 cuts off the power. At this time, the grinding needle falls into the collection basket 3 under the action of gravity, realizing the function of automatically recovering the grinding needle.

[0029] In use, the workpiece to be ground, the grinding needle, and the additive are placed in the container 7. The equipment is started by the industrial control computer 2, and the electric push cylinder 20 extends to drive the cylindrical electromagnet 21 to descend. When the cylindrical electromagnet 21 descends into the container 7, the industrial control computer 2 energizes the bar electromagnet 12 to generate a magnetic field. The stirring motor 14 drives the turntable 11 and the bar electromagnet 12 to rotate. The bar electromagnet 12 drives the grinding needle in the container 7 to rotate. At this time, the cylindrical electromagnet 21 is intermittently energized. The magnetic force of the cylindrical electromagnet 21 attracts the grinding needle during the rotation of the grinding needle, making the movement state of the grinding needle more complex and increasing the flipping and throwing of the grinding needle during movement, thereby improving the grinding efficiency.

[0030] After grinding is completed, the industrial control computer 2 cuts off the power to the bar electromagnet 12 while increasing the current to the cylindrical electromagnet 21. The grinding needle is attracted to the outer wall of the cylindrical electromagnet 21 by magnetic force. After attraction, the electric push rod retracts, causing the cylindrical electromagnet 21 to carry the grinding needle away. The rotating motor 16 drives the rotating shaft 17 to rotate. The rotating shaft 17 moves the mounting plate 19 and the cylindrical electromagnet 21 above the collection basket 3. Then the electric push rod extends and moves the cylindrical electromagnet 21 closer to the collection basket 3 to prevent the grinding needle from being damaged by falling. Finally, the industrial control computer 2 cuts off the power to the cylindrical electromagnet 21. At this time, the grinding needle falls into the collection basket 3 under the action of gravity, realizing the function of automatically recovering the grinding needle.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
