[0002] At present, when the surface of neodymium iron boron rare earth blanks is treated, grinding is required to reduce its surface roughness. During the existing surface grinding process of neodymium iron boron rare earth blanks, iron filings are likely to fly in the grinding environment, which is likely to cause scratches to the operators, and the flying iron filings and waste are not convenient for recycling, resulting in waste of iron filings resources.

[0003] Therefore, there is a processing device for neodymium iron boron rare earth with the patent number CN214054638U. However, while solving the above problems, this device has the following defects. For example, it cannot effectively grind the two end faces of the product. After one end face of the product is ground, it is necessary to manually flip and adjust the product by workers before the other end face can be ground. This undoubtedly increases the labor intensity and reduces the processing efficiency. Summary of the Invention

Specific embodiments

[0021] The following is a further specific description of the technical solution of the present invention through embodiments and in conjunction with the attached Figures 1-3 drawings.

[0022] A grinding device for neodymium iron boron processing, including a box body 1 with a switch door 2 provided on the side wall:

[0023] On both sides inside the box body 1, a clamping mechanism 3 is provided. A support mechanism 4 is provided inside the box body 1 below two groups of the clamping mechanisms 3, and a grinding mechanism 5 is provided at the top inside the box body 1 directly above the support mechanism 4;

[0024] The clamping mechanism 3 includes a clamping plate 31. A cross bar 32 penetrating the side wall of the box body 1 is provided on the back of the clamping plate 31, and a sleeve 17 for the cross bar 32 to pass through is provided on the side wall of the box body 1. A motor I 33 connected to the cross bar 32 is provided outside the box body 1. The motor I 33 is provided on a mounting seat 34, and the mounting seat 34 is driven by an electric push rod I 35;

[0025] The support mechanism 4 includes a support plate 42 driven by an electric push rod II 41. A cylinder 43 sleeved on the electric push rod II 41 is provided at the bottom of the support plate 42;

[0026] The grinding mechanism 5 includes a mounting plate 52 driven by a hydraulic rod 51. A motor II 53 is provided on the mounting plate 52, and a grinding seat 54 located below the mounting plate 52 is provided on the output shaft of the motor II 53. A protective cylinder 55 in the shape of a frustum and inverted is provided at the top edge of the mounting plate 52;

[0027] A base 6 is provided at the bottom inside the box body 1. An aggregate chute 7 is provided in a ring shape around the top of the base 6. The aggregate chute 7 has a structure with a larger upper part and a smaller lower part, and a fan 8 and an electromagnet 9 are also provided inside the aggregate chute 7. The fan 8 is provided at the top opening of the aggregate chute 7, the electromagnet 9 is provided at the bottom inside the aggregate chute 7, and an air outlet pipe 10 communicating with the aggregate chute 7 is also provided on the bottom side wall of the box body 1. A dust removal cloth bag 11 is fixed on the air outlet pipe 10.

[0028] In this embodiment, rectangular frames 12 for accommodating the corresponding motor I33 and electric push rod I35 are arranged on both sides of the box body 1. The dust removal cloth bag 11 is located within the openings of the corresponding rectangular frames 12. On the inner top wall of the rectangular frame 12, a chute 13 with an isosceles trapezoidal cross-section is arranged along its length direction. The upper end of the chute 13 communicates with the opening inside the rectangular frame 12. A slider 14 adapted to the chute 13 is arranged within the chute 13, and the slider 14 is connected to the mounting seat 34 through a vertical rod 15.

[0029] By the way of hanging the slider 14 through the chute 13, the slider 14 fixes the mounting seat 34 and the motor I33 through the vertical rod 15, thereby sharing the extrusion force caused by the above components on the electric push rod I35.

[0030] As Figure 2 shown, a groove for accommodating the electric push rod II41 is arranged on the top of the base 6. A card slot 16 for accommodating the bottom end of the protective cylinder 43 is arranged in a circle around the top end surface of the base 6.

[0031] As Figure 1 、 2 、Figure 3 shows that the blank is placed on the support plate 42 through the opening and closing door 2 and supported and fixed by it. The electric push rod I35 drives the mounting seat 34 to drive the motor I33 to drive the cross bar 32 to move within the sleeve 17, so as to drive the clamping plate 31 to move towards the blank, achieving the purpose of clamping and fixing the blank by the left and right groups of clamping plates 31. At this time, both the upper and lower ends of the blank extend to the upper and lower sides of the clamping plate 31;

[0032] Then, the hydraulic rod 51 drives the mounting plate 52 to drive the motor II53 and the grinding seat 54 to move downwards to contact the top end surface of the blank at this time. At the same time, the motor II53 drives the grinding seat 54 to perform grinding work on the top end surface of the blank. When it is necessary to grind the other end surface of the blank, the electric push rod II41 drives the support plate 42 to move downwards. The support plate 42 drives the cylinder 43 to move downwards within the card slot 16, while the grinding seat 54 moves upwards and resets. Then, by driving the cross bar 32 by the motor I33 to drive the clamping plate 31 to rotate, the blank clamped and fixed by the two groups of clamping plates 31 can be rotated by 180 degrees. During this process, the downward-moved support plate 42 and the reset grinding seat 54 will not obstruct the rotating blank. Then, the support plate 42 moves upwards to support the blank, and the grinding seat 54 moves downwards to perform grinding work on the top end surface of the blank at this time, thus achieving the purpose of grinding the two end surfaces of the product;

[0033] In the above process, since the output shafts of the motor I33 and the electric push rod I35 are both located outside the box body 1, the output shaft of the electric push rod II41 is covered by the cylinder 43, and the output shaft of the hydraulic rod 51 is blocked by the protective cylinder 55, so that the debris generated by grinding will not contact the output shafts of the above-mentioned devices. Then, the problem that the output shafts of the above components are worn under the influence of sputtered debris and the sealing performance is damaged during their retraction process will not occur.

[0034] During the grinding process, the blower 8 works to suck the dust diffused in the box body 1, forcing the dust to flow downward. The sputtered particles will be adsorbed by the electromagnet 9 for collection, preventing them from entering the air outlet pipe 10 and the dust removal bag 11 together with the gas and dust. At this time, the dust is filtered by the dust removal bag 11, and the gas is discharged. While realizing the collection and treatment of the debris obtained by grinding, the gas can also be filtered. Finally, the electromagnet 9 is powered off to facilitate the removal of the debris it adsorbs.

[0035] The above has described the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
