Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: a milling cutter step grinding mechanism, including the main body 1 of the step grinding equipment; in order to avoid the safety risk of manual grinding, a fixing device 2 is provided on the main body 1 of the step grinding equipment, a grinding device 3 is provided on the main body 1 of the step grinding equipment, a fixed installation box 4 is installed on the main body 1 of the step grinding equipment, and a milling cutter bar stock 5 is installed on the fixed installation box 4. The raw material is fixed by the fixing device 2 and ground by the grinding device 3;

[0023] In order to achieve the function of not requiring manual holding, the fixing device 2 includes a first rotating wheel 207, the first rotating wheel 207 is installed on one side of the fixed installation box 4, a second rotating wheel 208 is installed on one side of the first rotating wheel 207, first rotating shafts 209 are installed on both the first rotating wheel 207 and the second rotating wheel 208, a first gear 211 is installed on the first rotating shaft 209, a second rotating shaft 210 is installed below the first rotating shaft 209, a second gear 212 is installed on the second rotating shaft 210, the first gear 211 meshes with the second gear 212, one end of the second rotating shaft 210 on one side is installed with a rotating motor 216, a first pulley 213 is installed on the second rotating shaft 210 on the side of the rotating motor 216, a second pulley 214 is installed on the second rotating shaft 210 on the other side, the same belt 215 is installed on the first pulley 213 and the second pulley 214, a limit fixing block 201 is installed on the side of the fixed installation box 4 away from the first rotating wheel 207, a limit shaft 200 is installed in the limit fixing block 201, a locking bolt 202 is installed on the limit shaft 200, a groove is opened on the fixed installation box 4, the milling cutter bar stock 5 is installed in the groove, an upper fixing wheel 203 is installed on the milling cutter bar stock 5, a pressure rod mounting seat 204 is installed on the upper fixing wheel 203, a fixing wheel connecting seat 206 is installed on the fixed installation box 4, a fixed wheel pressure rod 205 is rotatably installed on the fixing wheel connecting seat 206, the fixed wheel pressure rod 205 is connected to the pressure rod mounting seat 204, place the milling cutter bar stock 5 in the groove on the fixed installation box 4, adjust the position of the limit shaft 200 in the limit fixing block 201 so that the end face of the limit shaft 200 abuts against the tail end of the milling cutter bar stock 5, and then tighten the locking bolt 202. When the locking bolt 202 is tightened, the limit shaft 200 is limited, so that the milling cutter bar stock 5 can be limited by the limit shaft 200 to prevent the milling cutter bar stock 5 from moving backward during grinding. The milling cutter bar stock 5 is supported by the first rotating wheel 207 and the second rotating wheel 208. The rotating motor 216 drives the second rotating shaft 210 on one side to rotate. When the second rotating shaft 210 on one side rotates, the first gear 211 is driven to rotate by the second gear 212 on the same side. The first gear 211 drives the first rotating shaft 209 and the first rotating wheel 207 to rotate. When the second rotating shaft 210 connected to the rotating motor 216 rotates, the first rotating wheel 207 is driven to rotate. The first rotating wheel 207 drives the second rotating wheel 208 to rotate through the belt 215. The second rotating wheel 208 drives the second rotating shaft 210 to rotate. The second rotating shaft 210 drives the second gear 212 on its same side to rotate. The second gear 212 drives the first gear 211 above to rotate. When the first gear 211 rotates, the second rotating wheel 208 is driven to rotate through the first rotating shaft 209. Thus, when the first rotating wheel 207 and the second rotating wheel 208 rotate, the milling cutter bar stock 5 is driven to rotate. When grinding, press down the fixed wheel pressure rod 205 so that the upper fixed wheel 203 is stuck on the milling cutter bar stock 5. Thus, the milling cutter bar stock 5 is supported by the first rotating wheel 207, the second rotating wheel 208 and the upper fixed wheel 203, and grinding does not require manual holding.When the grinding machine installation box 301 moves on the first electric slide rail 300, the left and right positions of the pressure rod mounting seat 204 can be adjusted.

[0024] The working principle is as follows: Place the milling cutter bar stock 5 in the groove on the fixed installation box 4, adjust the position of the limit shaft 200 in the limit fixing block 201 so that the end face of the limit shaft 200 abuts against the tail end of the milling cutter bar stock 5, and then tighten the locking bolt 202. When the locking bolt 202 is tightened, it limits the limit shaft 200, so that the limit shaft 200 can be used to limit the milling cutter bar stock 5 to prevent the milling cutter bar stock 5 from moving backward during grinding. Support the milling cutter bar stock 5 through the first rotating wheel 207 and the second rotating wheel 208. Drive the second rotating shaft 210 on one side to rotate through the rotating motor 216. When the second rotating shaft 210 on one side rotates, drive the first gear 211 to rotate through the second gear 212 on the same side. The first gear 211 drives the first rotating shaft 209 and the first rotating wheel 207 to rotate. When the second rotating shaft 210 connected to the rotating motor 216 rotates, it drives the first rotating wheel 207 to rotate. The first rotating wheel 207 drives the second rotating wheel 208 to rotate through the belt 215. The second rotating wheel 208 drives the second rotating shaft 210 to rotate. The second rotating shaft 210 drives the second gear 212 on its same side to rotate. The second gear 212 drives the first gear 211 above to rotate. When the first gear 211 rotates, it drives the second rotating wheel 208 to rotate through the first rotating shaft 209. Thus, when the first rotating wheel 207 and the second rotating wheel 208 rotate, they drive the milling cutter bar stock 5 to rotate. When grinding, press down the fixed wheel pressure rod 205 so that the upper fixed wheel 203 is stuck on the milling cutter bar stock 5. Thus, use the first rotating wheel 207, the second rotating wheel 208 and the upper fixed wheel 203 to support the milling cutter bar stock 5, eliminating the need for manual holding during grinding. When the grinding machine installation box 301 moves on the first electric slide rail 300, the left and right positions of the pressure rod mounting seat 204 can be adjusted. When the grinding machine mounting plate 303 moves on the second electric slide rail 302, the front and back positions of the grinding machine 304 can be adjusted, so that the milling cutter bar stock 5 can be ground with a step difference. The setting of the protective cover 305 can block the grinding wheel and the debris during grinding, increasing the safety during grinding.

[0025] Example 2: As Figures 1-4, in order to achieve the function of safe step grinding, the grinding device 3 includes a first electric slide rail 300, which is installed on the main body 1 of the step grinding equipment. A grinding machine installation box 301 is slidably installed on the first electric slide rail 300. A second electric slide rail 302 is installed on the grinding machine installation box 301. A grinding machine installation plate 303 is slidably installed on the second electric slide rail 302. A grinding machine 304 is installed on the grinding machine installation plate 303. A protective cover 305 is installed above the grinding machine 304. The protective cover 305 is connected to one side of the grinding machine installation plate 303. When the grinding machine installation plate 303 moves on the second electric slide rail 302, the front and rear positions of the grinding machine 304 can be adjusted, so that the step grinding of the milling cutter bar 5 can be carried out. The setting of the protective cover 305 can block the grinding wheel and the debris during grinding, increasing the safety during grinding. The remaining features are the same as those in Embodiment 1.
