Neodymium iron boron magnets are widely used in electronic products, such as hard disks, mobile phones, earphones, and battery-powered tools, etc. At the same time, they are also used in the adsorption ends of processing equipment, and they have excellent effects in many products.

[0003] Existing magnets lack wear-resistant structures on the end faces and side surfaces, and the overall wear resistance needs to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a wear-resistant neodymium iron boron magnet that can perform wear-resistant protection on the end face and side surface, and can effectively improve the wear resistance and service life of the magnet.

[0008] Further, the end face of the wear-resistant end block is higher than the end face of the protrusion.

[0012] Further, a plurality of evenly spaced card slots are provided on the side surface of the magnet, a plurality of wear-resistant strips are fixedly connected to the edge position of the wear-resistant frame, and the wear-resistant strips are inserted inside the card slots.

[0013] By adopting the above technical solution, the position stability of the wear-resistant strip can be improved.

[0014] Furthermore, the side surface of the wear-resistant strip protrudes from the side surface of the magnet.

[0016] Furthermore, a rectangular block-shaped connecting block is installed on the end surface of the magnet, and the connecting block and the magnet are fixedly connected by a second bolt.

[0017] By adopting the above technical solution, the connection between the connecting block and the magnet can be conveniently carried out, and at the same time, the magnet can be conveniently installed on the external structure.

[0018] In summary, the beneficial technical effects of the present utility model are as follows:

At this time, the wear-resistant end block provided on the wear-resistant frame can effectively prevent the adsorbed object from directly contacting the end surface of the magnet, effectively avoiding the wear of the end surface of the magnet. At the same time, the wear-resistant frame can be conveniently replaced after long-term use, and the overall practicability is strong;

[0020] 2. The present utility model inserts a plurality of wear-resistant strips on the side surface of the magnet. The side surface of the wear-resistant strip is higher than the side surface of the magnet, so that the wear-resistant strip can be used to prevent the side surface of the magnet from being worn, further improving the service life and practicability of the magnet.

[0024] The following further details the method of the present utility model with reference to the accompanying drawings.

[0025] Refer to Figure 1, a wear-resistant neodymium iron boron magnet, comprising a magnet 1. A wear-resistant frame 3 is installed on one end face of the magnet 1. A plurality of wear-resistant end blocks 4 are integrally connected to the outer surface of the wear-resistant frame 3. A plurality of protrusions 8 are integrally connected to the end face of the magnet 1. A plurality of through grooves 5 are provided on the wear-resistant frame 3. The protrusions 8 are placed inside the through grooves 5. The end face of the wear-resistant end block 4 is higher than the end face of the protrusion 8. A plurality of connecting sections 7 are provided on the wear-resistant frame 3. Threaded holes corresponding in position are provided on the outer surfaces of the connecting sections 7 and the outer surface of the magnet 1, and a first bolt 6 is threadedly connected inside the threaded holes. Among them, the wear-resistant frame 3 can be used to cover the end face of the magnet 1. At this time, the wear-resistant end blocks 4 provided on the wear-resistant frame 3 can effectively prevent the adsorbed object from directly contacting the end face of the magnet 1, effectively preventing the end face of the magnet 1 from being worn. At the same time, the wear-resistant frame 3 can be conveniently replaced after long-term use, and the overall practicality is strong.

[0026] Refer to Figure 1 , a plurality of evenly spaced card slots 2 are provided on the side surface of the magnet 1. A plurality of wear-resistant strips 11 are fixedly connected to the edge position of the wear-resistant frame 3. The wear-resistant strips 11 are inserted into the card slots 2. The side surface of the wear-resistant strip 11 protrudes from the side surface of the magnet 1. Among them, by inserting a plurality of wear-resistant strips 11 on the side surface of the magnet 1 and the side surface of the wear-resistant strip 11 being higher than the side surface of the magnet 1, the wear-resistant strips 11 can be used to prevent the side surface of the magnet 1 from being worn, further improving the service life and practicality of the magnet 1.

[0027] Refer to Figure 2 , a rectangular block-shaped connecting block 10 is installed on the end face of the magnet 1. The connecting block 10 and the magnet 1 are fixedly connected by a second bolt 9. Among them, the connecting block 10 can be firmly installed on the end face of the magnet 1 by using the second bolt 9, and then the connecting block 10 is installed on an external base, effectively limiting and fixing the magnet 1.

[0028] Working principle: When in use, first install the wear-resistant frame 3 on the end face of the magnet 1. Since the wear-resistant strip 11 is fixedly connected to the wear-resistant frame 3, the wear-resistant strip 11 can effectively be inserted into the card slot 2. Then use the first bolt 6 to firmly fix the wear-resistant frame 3 on the end face of the magnet 1. Then fix the connecting block 10 on the other end face of the magnet 1 through the second bolt 9, and then fix the connecting block 10 to the external base. At this time, the magnet 1 can be used normally. Since the end face of the wear-resistant end block 4 is higher than the end face of the protrusion 8 and the side surface of the wear-resistant strip 11 protrudes from the side surface of the magnet 1, it can effectively prevent the adsorbed object from directly contacting the end face and side surface of the magnet 1, thereby preventing the magnet 1 from being worn.

[0029] The real-time examples of this specific real-time mode are all preferred real-time examples of the present utility model, and do not limit the protection scope of the present utility model. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
