[0002] Columnar milling cutters play an important role in the field of machining. As key cutting tools, the performance and quality of their cutting edges have a decisive impact on machining efficiency and workpiece quality. Especially in the core process of milling operations, when dealing with workpieces of different materials and shapes, the existing columnar milling cutters gradually expose obvious limitations and technical problems in inconvenient blade replacement. Specifically, in the design of the existing columnar milling cutters, the cutting edges, as consumables, need to be replaced after long-term use. However, when replacing the cutting edges, the cutter head needs to be separated from the cutter body, but the existing connection method is relatively complex and the disassembly process is rather troublesome. This not only directly leads to a reduction in replacement efficiency but also increases the operation complexity, making it difficult to meet the requirements of high-efficiency and fast-paced production. More seriously, this inconvenient replacement method may also affect the machining accuracy, increase the costs and risks in the production process, and pose potential risks to the overall machining quality and efficiency.

Specific embodiments

[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] Example 1, referring to Figures 1-5 , a columnar milling cutter with a replaceable milling cutter blade, including a cutter head 1, a mounting post 3 for connecting with the cutter body is arranged on one side of the cutter head 1, hidden grooves 8 are opened at the centers of both sides of the cutter head 1, circular grooves are opened at the centers of the interiors of the two hidden grooves 8, and the interiors of the two circular grooves are communicated with each other through a through hole 9;

[0026] A mounting plate 2 is arranged inside each hidden groove 8, a central column 12 adapted to the circular groove is connected to the center of one side of the mounting plate 2, and a screw hole 11 penetrating through the central column 12 and the mounting plate 2 is opened at one end of the central column 12;

[0027] A connecting screw 15 adapted to the screw hole 11 is arranged on the side of the cutter head 1 away from the mounting post 3, and a docking column 14 is connected to one end of the connecting screw 15;

[0028] One end of the mounting post 3 is connected with a docking rod 5, a docking groove 6 adapted to the docking column 14 is opened at the center of one end of the docking rod 5, the outer ring of the end of the docking rod 5 is detachably connected with the side wall of the adjacent mounting plate 2 through a positioning plate 7, and the mounting plate 2 is bolted and fixed to the inner wall of the hidden groove 8.

[0029] This solution has the following working process:

[0030] When using this cylindrical milling cutter, first, connect the cutter head 1 to the cutter body through the mounting post 3. When the cutting edge needs to be replaced, the operator only needs to first release the detachable connection between the mounting plate 2 and the docking rod 5 through the positioning plate 7, and then loosen the bolted connection between the mounting plate 2 and the inner wall of the hidden groove 8, and take out the mounting plate 2 from the hidden groove 8. At this time, the connecting screw 15 and the docking post 14 can be exposed. Then, through a rotating operation, the connecting screw 15 is screwed out of the screw hole 11, and the old cutter head 1 can be removed from the mounting post 3 and a new cutter head can be installed. Finally, insert the new mounting plate 2 into the hidden groove 8, fix it with bolts, and then make the mounting plate 2 and the docking rod 5 in a detachable connection through the positioning plate 7 to complete the replacement of the cutting edge.

[0031] According to the above working process, it can be known that:

[0032] The efficiency of cutting edge replacement is significantly improved, the operation process is simplified, the operation complexity is reduced, making the cutting edge replacement faster and more convenient; at the same time, it better meets the production requirements of modernization and high efficiency, improves the production efficiency of machining, and reduces the production cost; in addition, by quickly replacing the cutting edge, it also helps to improve the machining quality of workpieces, reduce the rejection rate, and further enhance the production efficiency and market competitiveness of the enterprise; finally, this design also helps to extend the overall service life of the cylindrical milling cutter, and reduces the cost and time of repairing and replacing the cutter body. In summary, this design not only solves the technical problems of the existing cylindrical milling cutter, but also provides strong support for the sustainable development of the machining industry.

[0033] Example 2, refer to Figures 1-5 , the depth of the hidden groove 8 is 2 - 5 mm, and the thickness of the mounting plate 2 is the same as the depth of the hidden groove 8. Specifically, through the setting of the hidden groove 8 and the mounting plate 2, in the working process, the hidden groove 8 provides an installation space for the mounting plate 2, enabling the mounting plate 2 to be hidden inside the cutter head 1 when not in use, maintaining the cleanliness of the cutter head 1 and the integrity of the appearance. At the same time, the thickness of the mounting plate 2 is the same as the depth of the hidden groove 8, ensuring that the mounting plate 2 can be completely embedded in the hidden groove 8, further enhancing the structural strength and stability of the cutter head 1. This design achieves the effect of being both beautiful and practical.

[0034] The length of the connecting screw 15 is greater than the thickness of the cutter head 1, and a cross slot is provided at the end of the connecting screw 15. Specifically, through the setting of the connecting screw 15 and the screw hole 11, in the working process, the length of the connecting screw 15 is greater than the thickness of the cutter head 1, ensuring that the connecting screw 15 can completely pass through the cutter head 1 and be connected to the screw hole 11, providing sufficient connection strength and stability. At the same time, the cross slot provided at the end of the connecting screw 15 facilitates the operator to use tools for rotating operation, further simplifying the process of cutting edge replacement. This design achieves the effect of improving the connection strength and simplifying the operation.

[0035] On one side of the mounting plate 2 close to the central column 12, a number of limiting posts 13 are connected. A number of limiting holes 10 adapted to the limiting posts 13 are provided at the bottom of the inner cavity of the hidden groove 8. Specifically, through the arrangement of the limiting posts 13 and the limiting holes 10, in the working process, the mutual cooperation of the limiting posts 13 and the limiting holes 10 accurately positions and fixes the position of the mounting plate 2 in the hidden groove 8, preventing the mounting plate 2 from shifting or loosening during use. This design achieves the effect of improving the stability and positioning accuracy of the mounting plate 2.

[0036] A number of mounting holes 4 are provided on the outer circumference of the mounting post 3. The size of the positioning plate 7 is larger than that of the docking rod 5. Specifically, through the arrangement of the mounting holes 4 and the positioning plate 7, in the working process, the mounting holes 4 provide a mounting position for the positioning plate 7, enabling the positioning plate 7 to be firmly connected to the outer circumference of the mounting post 3. At the same time, the size of the positioning plate 7 is larger than that of the docking rod 5, ensuring that the positioning plate 7 can effectively position and fix the mounting plate 2. This design achieves the effect of enhancing the connection stability and improving the positioning accuracy.

[0037] The positioning plate 7 is made of a metal material. The shape of the docking post 14 is rectangular. Specifically, through the arrangement of the positioning plate 7 and the docking post 14, in the working process, the metal positioning plate 7 has high strength and wear resistance, and can maintain the fastening and positioning effect on the mounting plate 2 for a long time. At the same time, the shape of the docking post 14 is rectangular, matching the shape of the docking groove 6, ensuring that the docking post 14 can accurately insert into the docking groove 6 and realizing the firm connection between the docking rod 5 and the tool head 1. This design achieves the effect of improving the connection strength and stability.

[0038] In summary: When using this end mill, first, connect the cutter head 1 to the tool body through the mounting post 3. At this time, the mounting hole 4 provides a mounting position for the positioning plate 7. The positioning plate 7 can be firmly connected to the outer circle of the mounting post 3 and maintain the fastening and positioning of the mounting plate 2. When the cutting edge needs to be replaced, the operator only needs to first release the detachable connection between the mounting plate 2 and the docking rod 5 through the positioning plate 7, and then loosen the bolted connection between the mounting plate 2 and the inner wall of the hidden groove 8. Due to the mutual cooperation of the limit post 13 and the limit hole 10, the position of the mounting plate 2 in the hidden groove 8 is accurately positioned and fixed, preventing the mounting plate 2 from shifting or loosening during the loosening process, so that the mounting plate 2 can be smoothly removed from the hidden groove 8. At this time, the connecting screw 15 and the docking post 14 can be exposed. Then, through rotation operation, using the cross groove opened at the end of the connecting screw 15, the operator can conveniently use tools to screw out the connecting screw 15 from the screw hole 11, and then remove the old cutter head 1 from the mounting post 3 and replace it with a new cutter head. Finally, insert the new mounting plate 2 into the hidden groove 8 and fix it with bolts. At this time, the limit post 13 and the limit hole 10 cooperate with each other again to accurately position and fix the new mounting plate 2. Then, connect the mounting plate 2 and the docking rod 5 through the positioning plate 7 for detachable connection to complete the replacement of the cutting edge.

[0039] Advantages: The design of this new type of end mill with quickly replaceable milling cutter blades significantly improves the efficiency of cutting edge replacement, simplifies the operation process, reduces the operation complexity, and makes the cutting edge replacement faster and more convenient. Specifically, the setting of the hidden groove 8 and the mounting plate 2 not only keeps the cutter head 1 clean and the appearance intact, but also enhances the structural strength and stability of the cutter head 1; the setting of the connecting screw 15 and the screw hole 11 provides sufficient connection strength and stability, and at the same time facilitates the operator to use tools for rotation operation; the setting of the limit post 13 and the limit hole 10 improves the stability and positioning accuracy of the mounting plate 2; the setting of the mounting hole 4 and the positioning plate 7 enhances the connection stability and improves the positioning accuracy; the setting of the positioning plate 7 made of metal and the rectangular docking post 14 further improves the connection strength and stability. In summary, this design not only solves the technical problems of existing end mills, such as inconvenient cutting edge replacement, complex disassembly process, low replacement efficiency, high operation complexity, and possible impact on machining accuracy, etc., but also provides strong support for the sustainable development of the machining industry. By quickly replacing the cutting edge, it helps to improve the machining quality of workpieces, reduce the scrap rate, and further enhance the production efficiency and market competitiveness of enterprises. At the same time, this design also helps to extend the overall service life of the end mill and reduces the cost and time of repairing and replacing the tool body.
