Description

Technical Field

[0001] This utility model relates to the field of grinding disc technology, specifically a high-concentration wear-resistant alloy grinding disc. Background Technology

[0002] Grinding discs are widely used in the processing of industrial products, mainly for grinding and polishing. They are used extensively in everything from automobile, ship, and aerospace manufacturing to the grinding of jade, shoe heels, stainless steel products, and furniture.

[0003] Traditional grinding discs are mostly of one-piece structure, so they will wear out after prolonged use. When a single part of the grinding disc is damaged, the entire grinding disc body needs to be replaced, which increases the replacement cost and the overall cost of using the grinding disc. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-concentration wear-resistant alloy grinding disc, which solves the problem mentioned in the background art that most traditional grinding discs are of a single-piece structure. Therefore, after prolonged use, the grinding disc will wear out. When a single part of the grinding disc is damaged, the entire grinding disc body needs to be replaced, which increases the replacement cost and the overall cost of using the grinding disc.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-concentration wear-resistant alloy grinding disc, comprising a grinding disc body, a mounting groove formed on one end face of the grinding disc body, a mounting block fixedly mounted on the other end of the grinding disc body, two mounting holes formed on both the mounting block and the grinding disc body, a positioning groove formed above the mounting holes formed on the grinding disc body, a base plate provided at the bottom of the grinding disc body, a positioning post fixedly mounted on the upper end of the base plate, the positioning post penetrating to the mounting holes, a threaded hole formed in the positioning post, and a positioning bolt provided in the threaded hole.

[0006] Using the above technical solution, after removing the positioning bolts from the positioning posts, the operator removes the substrate from the grinding disc body, thereby removing the constraints between the several grinding disc bodies. Then, the mounting block of the damaged grinding disc body is removed from the mounting groove in another grinding disc body. The operator then inserts the mounting block from the new grinding disc body into the mounting groove in another grinding disc body. After that, the operator inserts the positioning posts into the mounting holes, and then installs the positioning bolts into the threaded holes in the positioning posts, thereby fixing the grinding disc bodies together. Therefore, when the grinding disc body is excessively worn, only the excessively worn grinding disc needs to be replaced.

[0007] Preferably, the grinding disc body has a plurality of first grinding grooves near the outer end and a plurality of second grinding grooves near the inner end.

[0008] By adopting the above technical solution, the first and second grinding grooves set on the grinding disc body can make the material stay in them when grinding the item, thereby ensuring the grinding effect.

[0009] Preferably, the mounting holes on the mounting block and the mounting holes on the grinding disc body are positioned correspondingly, and the diameters of the mounting holes on the mounting block and the mounting holes on the grinding disc body are equal.

[0010] By adopting the above technical solution, the diameter of the mounting hole on the mounting block is equal to the diameter of the mounting hole on the grinding disc body, so that the positioning post can be inserted into it in a better way, thereby fixing the grinding disc body.

[0011] Preferably, the diameter of the positioning post on the substrate is equal to the diameter of the mounting hole on the mounting block and the grinding disc body, and the threaded hole in the positioning post and the positioning bolt mesh with each other.

[0012] By adopting the above technical solution, the positioning bolts are installed into the threaded holes on the positioning column, thereby stabilizing the splicing between the grinding disc bodies and preventing them from falling off.

[0013] Preferably, the grinding disc body is made of high-chromium alloy.

[0014] By adopting the above technical solution, the grinding disc body is made of high-chromium alloy, which improves the hardness and wear resistance of the grinding disc body, thus significantly extending its service life.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This high-concentration wear-resistant alloy grinding disc is designed to be fixed by removing the positioning bolts from the positioning posts and then removing the base plate from the grinding disc body. This process removes the constraints between the grinding disc bodies. Next, the mounting block of the damaged grinding disc body is removed from the mounting groove of another grinding disc body. Then, the mounting block of the new grinding disc body is inserted into the mounting groove of another grinding disc body. Finally, the positioning posts are inserted into the mounting holes, and the positioning bolts are installed into the threaded holes within the positioning posts. This allows the grinding disc bodies to be fixed together by the positioning bolts. Therefore, when the grinding disc body becomes excessively worn, only the excessively worn grinding disc needs to be replaced.

[0017] 2. This high-concentration wear-resistant alloy grinding disc stabilizes the splicing between the grinding disc bodies by inserting positioning posts on the substrate. Then, positioning bolts are installed into the threaded holes on the positioning posts, further stabilizing the splicing between the grinding disc bodies and preventing them from falling off. Furthermore, the grinding disc body is made of high-chromium alloy, which significantly improves its hardness and wear resistance, thus extending its service life. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Referring to Figures 1-4, a high-concentration wear-resistant alloy grinding disc is described. One end face of the grinding disc body 1 has a mounting groove 2. A mounting block 3 is fixedly mounted at the other end of the grinding disc body 1. Both the mounting block 3 and the grinding disc body 1 have two mounting holes 4. A positioning groove 5 is formed above the mounting holes 4 on the grinding disc body 1. A base plate 6 is provided at the bottom of the grinding disc body 1. A positioning post 7 is fixedly mounted at the upper end of the base plate 6, penetrating to the mounting holes 4. The positioning post 7 has a threaded hole 8, and a positioning bolt 9 is provided in the threaded hole 8. The mounting hole 4 on the mounting block 3 and the mounting hole 4 on the grinding disc body 1 are positioned correspondingly. The diameter of the mounting hole 4 on the mounting block 3 and the diameter of the mounting hole 4 on the grinding disc body 1 are equal. The diameter of the positioning post 7 on the substrate 6 is equal to the diameter of the mounting hole 4 on the mounting block 3 and the grinding disc body 1. The threaded hole 8 and the positioning bolt 9 in the positioning post 7 are engaged with each other.

[0026] Working principle: When a single grinding disc is damaged and needs to be replaced, the operator removes the grinding disc body 1, then removes the positioning bolt 9 from the positioning post 7, and then removes the base plate 6 from the grinding disc body 1, thus removing the constraint between the several grinding disc bodies 1. After the base plate 6 is removed, the operator removes the mounting block 3 of the damaged grinding disc body 1 from the mounting groove 2 in another grinding disc body 1, thus allowing the operator to disassemble the damaged grinding disc body 1 individually. Then, the operator inserts the mounting block 3 from the new grinding disc body 1 into the mounting groove 2 in another grinding disc body 1. Next, the operator inserts the positioning post 7 into the mounting hole 4, so that the positioning post 7 passes through the grinding disc body 1 and the mounting block 3. Finally, the positioning bolt 9 is installed into the threaded hole 8 in the positioning post 7, thus fixing the grinding disc bodies 1 together. Therefore, when the grinding disc body 1 is excessively worn, only the excessively worn grinding disc needs to be replaced, instead of replacing the entire grinding disc, thus significantly reducing costs.

[0027] Example 2:

[0028] Referring to Figures 1-4, a high-concentration wear-resistant alloy grinding disc is described. The grinding disc body 1 has multiple first grinding grooves 10 near its outer end and multiple second grinding grooves 11 near its inner end. The mounting holes 4 on the mounting block 3 correspond to the mounting holes 4 on the grinding disc body 1, and their diameters are equal. The diameter of the positioning pins 7 on the substrate 6 is equal to the diameters of the mounting holes 4 on the mounting block 3 and the grinding disc body 1. The threaded holes 8 and positioning bolts 9 inside the positioning pins 7 mesh with each other. The grinding disc body 1 is made of high-chromium alloy.

[0029] Working principle: The first grinding groove 10 and the second grinding groove 11 set on the grinding disc body 1 allow the material to remain inside during grinding, thus ensuring a better grinding effect. Since the diameter of the mounting block 3 is equal to the diameter of the positioning post 7, after the mounting block 3 is inserted into the mounting hole 4, the operator inserts the positioning post 7 on the base plate 6 into it, thereby stabilizing the splicing between the grinding disc bodies 1. Then, the positioning bolt 9 is installed into the threaded hole 8 on the positioning post 7, thereby stabilizing the splicing between the grinding disc bodies 1 and preventing them from falling off. The grinding disc body 1 is made of high chromium alloy, which improves the hardness and wear resistance of the grinding disc body 1, thus improving its service life.
