[0002] A magnetic grinder is a device that uses a magnetic field to drive a grinding medium to perform precision processing on the surface of a workpiece.

[0027] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Example: Figure 1 - Figure 6 As shown, a chip adsorption device for manufacturing mechanical parts includes a shell 1, a avoidance shell 2 is fixedly installed on the rear side of the shell 1, a first electromagnet 5 is arranged inside the avoidance shell 2, a displacement mechanism is provided between the avoidance shell 2 and the shell 1, and the displacement mechanism is installed on the first electromagnet 5, a fixing frame 17 is fixedly connected to the inside of the shell 1, a grid plate 18 is fixedly connected to the inner side of the fixing frame 17, and a foam 10 is provided on the upper end surface of the grid plate 18, a telescopic electric cylinder 11 is fixedly installed on the bottom of the shell 1, and the output end of the telescopic electric cylinder 11 is arranged inside the shell 1, a second electromagnet 12 is installed on the output end of the telescopic electric cylinder 11, and the second electromagnet 12 is arranged below the grid plate 18, the magnetic poles of the opposite surfaces of the first electromagnet 5 and the second electromagnet 12 are opposite, and there is a certain distance between the avoidance shell 2 and the grid plate 18, and the surface of the second electromagnet 12 is provided with a detachable skin, and after the magnetic grinding needle falls on the skin, the skin can be removed to facilitate the blanking of the magnetic grinding needle;

[0029] The magnetic grinding needle after the initial screening is spread flat on the foam 10, and the telescopic electric cylinder 11 works to make the second electromagnet 12 abut against the lower end surface of the grid plate 18. Then the first electromagnet 5 is moved out of the avoidance housing 2 under the action of the displacement mechanism, so that the first electromagnet 5, the grid plate 18 and the second electromagnet 12 are in the same straight line. The first electromagnet 5 and the second electromagnet 12 are energized at the same time, so that a vertical magnetic field is formed between the first electromagnet 5 and the second electromagnet 12. At this time, the magnetic grinding needle is erected by the action of the magnetic field, and the erected magnetic grinding needle is attracted by the second electromagnet 12, so that the magnetic grinding needle passes through the foam 10 and contacts the second electromagnet 12. Then the telescopic electric cylinder 11 contracts to make the second electromagnet 12 move downward until the magnetic grinding needle passes through the foam 10. At this time, the iron filings on the surface of the magnetic grinding needle remain above the foam 10, so that the magnetic grinding needle is separated from the iron filings, and cleaning the iron filings is more convenient.

[0030] For further reference, Figure 3 and Figure 4 Material rollers 9 are installed on the left and right sides of the interior of the shell 1, and a motor is installed at the front end of the material roller 9. The material rollers 9 rotate synchronously. The foam 10 is a coil, and the two ends of the foam 10 are respectively wound on the two material rollers 9. Elastic sealing edges are provided on the front and back sides of the foam 10. The foam 10 in the form of a coil is put back and forth on the two material rollers 9, which can transport iron filings and replace the foam 10, reducing the frequency of replacing the foam 10 and making it more convenient to use.

[0031] Preferably, Figure 3 and Figure 4 , pressure rollers 13 are provided on the left and right sides above the foam 10, and the front and rear ends of the pressure roller 13 are installed with a first telescopic cylinder 14, and the first telescopic cylinder 14 is fixedly connected to the inside of the shell 1, and the axis of the material roller 9 is slightly higher than the grid plate 18. The first telescopic cylinder 14 works to push the pressure roller 13 downward, and the pressure roller 13 acts on the foam 10 and attaches the foam 10 to the grid plate 18. It can also make the foam 10 spread out flat, avoiding the magnetic grinding needles laid on the foam 10 from gathering together, affecting the grinding needles from standing up.

[0032] Specifically, refer to Figure 1 and Figure 3 The displacement mechanism includes a pair of threaded rods 6, which are rotatably installed inside the outer shell 1, and the rear end of the threaded rods 6 extends to the inside of the avoidance shell 2. The pair of threaded rods 6 are respectively threadedly connected to the left and right sides of the first electromagnet 5. A motor is installed at the front end of the threaded rods 6. The motor drives the threaded rods 6 to rotate, and drives the first electromagnet 5 to move through the threads, so that the first electromagnet 5 can be retracted into the avoidance shell 2 to avoid affecting the flattening of the magnetic grinding needle on the foam 10.

[0033] Specifically, such as Figure 1 、 Figure 2 and Figure 3The scraper 8 scrapes the iron filings from the conveyor belt 4 and falls into the material box 7, which is automatically discharged, making it more convenient to use.

[0034] Further, such as Figure 1 、 Figure 3 and Figure 6 The front bottom of the shell 1 is provided with an opening 3, the top of the telescopic electric cylinder 11 is fixedly connected to a supporting plate 24, and the top of the supporting plate 24 is provided with a slide groove 25. The inside of the slide groove 25 is slidably connected to a slider, and the slider is fixedly connected to the bottom end of the second electromagnet 12, and the top rear side of the supporting plate 24 is fixedly connected to a perforated plate 26. The rear end of the second electromagnet 12 is fixedly connected to an expansion rod 27, and the expansion rod 27 passes through the perforated plate 26. The second electromagnet 12 slides and presses on the supporting plate 24. After the telescopic electric cylinder 11 contracts and the second electromagnet 12 coincides with the opening 3, the second electromagnet 12 can be pulled out of the shell 1, so that the magnetic grinding needle on the second electromagnet 12 is moved out of the shell 1, which facilitates the unloading of the magnetic grinding needle. The second electromagnet 12 is inserted into the perforated plate 26 through the expansion rod 27 to fix the second electromagnet 12 on the supporting plate 24.

[0035] Further, such as Figure 4 and Figure 5 As shown, two guide rails 19 are fixedly installed at the bottom of the shell 1, and two movable blocks 21 are slidably connected to the outer sides of the two guide rails 19. The two movable blocks 21 on the same guide rail 19 are symmetrically arranged, and the top of the movable block 21 is hinged with a support rod 20, and the top of the support rod 20 is hinged with the supporting plate 24. The top of the movable block 21 is fixedly connected with a contact plate 22, and a spring 23 is installed on the side of the contact plate 22 facing the inner wall of the shell 1, and the spring 23 is fixedly connected to the inner wall of the shell 1. In the process of the supporting plate 24 moving up and down, the movable block 21 slides along the guide rail 19, so that the supporting plate 24 moves up and down more smoothly. In the process of the supporting plate 24 moving up and down, the movable block 21 will always be affected by the spring 23 when moving along the guide rail 19, so that the movable block 21 can move smoothly and keep the supporting plate 24 in a horizontal state as much as possible.

[0036] Further, such as Figure 3 and Figure 4 As shown, a pressing frame 15 is provided inside the shell 1, and a second telescopic cylinder 16 is provided on the front and rear sides of the pressing frame 15, and the second telescopic cylinder 16 is fixedly connected to the inside of the shell 1, and the cross-sectional shape of the pressing frame 15 is L-shaped. The lower end face of the pressing frame 15 is opposite to the fixed frame 17. After the foam 10 is covered on the grid plate 18, the second telescopic cylinder 16 works to push the pressing frame 15 toward the grid plate 18, and the pressing frame 15 cooperates with the fixed frame 17 to compact the edge position of the foam 10, so that the foam 10 fits tightly on the upper surface of the grid plate 18, so that the magnetic grinding needle can be better spread out, and the edge position of the top of the fixed frame 17 is provided with an outwardly inclined inclined surface, and the inner side of the bottom end of the pressing frame 15 is provided with a downwardly inclined inclined surface. After the pressing frame 15 and the fixed frame 17 are fitted with each other, the two inclined surfaces act on the edge position of the foam 10, which can stretch the foam 10 outward, so that the foam 10 can be better unfolded.

[0037] Working principle: The coiled foam 10 is wound on one of the material rollers 9, and the other end of the foam 10 is fixed to the other material roller 9. The tension of the foam 10 between the two material rollers 9 is adjusted. Then the first telescopic cylinder 14 and the second telescopic cylinder 16 are operated in sequence to push the pressing roller 13 and the pressing frame 15 downwards. The pressing roller 13 makes the foam 10 flat on the grid plate 18. The pressing frame 15 makes the foam 10 further open and fit tightly on the top of the grid plate 18. Then, the magnetic grinding needles after the initial screening are spread as flatly as possible on the foam 10.

[0038] The telescopic electric cylinder 11 works to make the second electromagnet 12 abut against the lower end surface of the grid plate 18, and the motor drives the threaded rod 6 to rotate. The rotating threaded rod 6 drives the first electromagnet 5 to move out of the avoidance housing 2 through the thread, keeping the first electromagnet 5, the grid plate 18 and the second electromagnet 12 in the same straight line. The first electromagnet 5 and the second electromagnet 12 are energized at the same time, so that a vertical magnetic field is formed between the first electromagnet 5 and the second electromagnet 12. At this time, the magnetic grinding needle is erected by the magnetic field, and the erected magnetic grinding needle is attracted by the second electromagnet 12, so that the bottom of the magnetic grinding needle passes through the foam 10 and contacts the upper end surface of the second electromagnet 12. After the magnetic grinding needle passes through the foam 10, the first electromagnet 5 is de-energized;

[0039] Then the telescopic cylinder 11 contracts, and the second electromagnet 12 moves downward. The descending second electromagnet 12 drags the magnetic grinding needle downward until the magnetic grinding needle passes through the foam 10. During the process of the magnetic grinding needle passing through the foam 10, iron filings are left on the foam 10 because the foam 10 and the surface of the magnetic grinding needle adhere to each other. As the telescopic cylinder 11 contracts, the magnetic grinding needle completely passes through the foam 10, and the second electromagnet 12 coincides with the opening 3.

[0040] Pull the second electromagnet 12 outward from the opening 3. The second electromagnet 12 moves outward along the slide groove 25 on the support plate 24, and the expansion rod 27 is pulled out of the perforated plate 26 until the magnetic grinding needle moves out of the housing 1. The magnetic grinding needle is manually removed. After removal, the second electromagnet 12 is reset.

[0041] The iron filings left on the foam 10 are retracted by the first telescopic cylinder 14 and the second telescopic cylinder 16, causing the pressing roller 13 and the pressing frame 15 to move upward. At this time, the motor drives the material rollers 9 to rotate, causing the foam 10 to be transferred from one material roller 9 to another. During the winding process of the foam 10, the iron filings on the foam 10 fall onto the conveyor belt 4 under the action of gravity and magnetic force, and then the conveyor belt 4 absorbs the iron filings and moves them out of the housing 1;

[0042] After the iron chips move out of the shell 1, they come into contact with the scraper 8, which is attached to the lower end surface of the conveyor belt 4. As the conveyor belt 4 rotates, the iron chips are concentrated on the scraper 8. As the iron chips accumulate, they eventually fall into the material box 7 along the scraper 8, completing the collection of the iron chips. At this time, the new foam 10 replaces the used foam 10, and the next round of iron chip separation operation can be carried out.

[0043] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
