[0002] Wind power equipment is equipment that uses wind energy to generate electricity or wind power. Wind power technology and equipment are an important part of the wind power industry and also the foundation and guarantee for its development. Wind power equipment generally requires milling during production and processing. In the existing technology, large milling cutter discs are generally used in the milling process of wind power equipment. Milling cutter discs are cutting tools used to mill the plane of workpieces in the machining process. Because they are larger than ordinary milling cutters and are shaped like discs, they are called milling cutter discs.

[0003] However, traditional milling cutter heads typically have the corresponding cutting edges mounted on the surface of the toothed edge according to the requirements, and then the cutter head is rotated by the cutter holder to perform milling on wind power equipment.

[0035] Please see Figures 1-10 This invention provides a technical solution: a large milling cutter head for milling wind turbine equipment, comprising: a milling shank 1, a fixed seat 2 on the lower surface of the milling shank 1, a insert plate 3 on the lower surface of the fixed seat 2, a threaded groove 4 on the surface of the insert plate 3, and locking blocks 5 on both sides of the lower surface of the fixed seat 2; a insert post 6, a threaded post 7 on the upper surface of the insert post 6, and a cross-shaped insert block 8 on the side of the lower end of the insert post 6; a milling cutter head 11, a groove 12 on the upper surface of the milling cutter head 11, locking grooves 13 on both sides of the groove 12, a screw seat 14 on the side of the milling cutter head 11, a locking screw 15 inside the screw seat 14, and a limiting plate 16 inside the milling cutter head 11, the surface of the limiting plate 16 having a... The limiting groove 17 and the limiting plate 16 are provided with a paddle 18 on the side. The outer end of the paddle 18 is provided with a locking hole 19. The milling cutter plate 11 is provided with a paddle groove 20 on the side. The lower surface of the milling cutter plate 11 is provided with a receiving seat 21. The receiving seat 21 is provided with a receiving groove 22 on the side. The receiving groove 22 is provided with a moving block 23. The rear end of the upper surface of the moving block 23 is provided with a limiting post 24. The front end of the lower surface of the moving block 23 is provided with a driven shaft 25. The end of the moving block 23 is provided with a milling tooth 26. The surface of the milling tooth 26 is provided with a cutting blade 27. The lower surface of the receiving seat 21 is provided with a pressing plate 28. The outer side of the surface of the pressing plate 28 is provided with a pressing groove 29. The upper surface of the pressing plate 28 is provided with a rotating shaft 35. The surface of the pressing plate 28 is provided with a cross hole 30.

[0036] When milling wind turbine equipment using the milling cutter head 11, first insert the insert plate 3 and the retaining block 5 into the plate groove 12 and retaining groove 13 respectively. Then, insert the threaded post 7 into the threaded groove 4 and insert the cross insert 8 into the cross hole 30. Rotate and screw the threaded post 7 into the threaded groove 4. At the same time, the cross insert 8 will drive the pressure plate 28 to rotate. The pressure plate 28 drives the milling teeth 26 at the end of the driven shaft 25 and the moving block 23 to extend through the pressure groove 29. At this time, the cutting tool 27 can be fixed to the surface of the milling teeth 26 with screws, and the milling cutter head 11 can be driven by the milling shank 1 to mill the wind turbine equipment. This installation and operation method is convenient and quick. When the milling cutter head 11 is needed for machining, the milling teeth 26 can extend synchronously during the installation of the milling cutter head 11. When the milling cutter head 11 is disassembled, the milling teeth 26 can be synchronously retracted into the milling cutter head 11 for storage. This reduces the possibility of the milling teeth 26 being bumped and damaged when the milling cutter head 11 is idle, thereby improving the service life of the milling cutter head 11. It also solves the problem that the teeth of traditional milling cutter heads are always exposed and may be damaged by bumping. This allows large milling cutter heads to have a longer service life. Example

[0037] Please see Figures 1-10 Based on Embodiment 1, in order to allow the milling teeth 26 to extend when the milling cutter disc 11 is installed, a fixing seat 2 is fixedly connected to the lower surface of the milling shank 1, a insert plate 3 is fixedly connected to the lower surface of the fixing seat 2, the threaded groove 4 on the surface of the insert plate 3 is columnar, a locking block 5 is fixedly connected to both sides of the lower surface of the fixing seat 2, a threaded post 7 is fixedly connected to the upper surface of the insert post 6, the threaded post 7 is threadedly connected to the threaded groove 4, a cross-shaped insert block 8 is fixedly connected to the side of the lower end of the insert post 6, the disc groove 12 on the upper surface of the milling cutter disc 11 is circular, the locking groove 13 on both sides of the disc groove 12 is block-shaped, a screw seat 14 is fixedly connected to the side of the milling cutter disc 11, a locking screw 15 is threadedly connected to the screw seat 14, a limiting disc 16 is rotatably connected to the milling cutter disc 11, the limiting groove 17 on the surface of the limiting disc 16 is plate-shaped, and a lever 18 is fixedly connected to... On the side of the limiting plate 16, the clamping hole 19 at the outer end of the surface of the paddle 18 is in the shape of a circular plate. The receiving seat 21 is fixedly connected to the lower surface of the milling cutter disc 11. The receiving groove 22 on the side of the receiving seat 21 is in the shape of a plate. The moving block 23 is slidably connected to the receiving groove 22. The limiting post 24 is fixedly connected to the rear end of the upper surface of the moving block 23. The limiting post 24 is slidably connected to the lower surface of the milling cutter disc 11. The driven shaft 25 is fixedly connected to the front end of the lower surface of the moving block 23. The milling tooth 26 is fixedly connected to the end of the moving block 23. The cutting blade 27 is fixedly connected to the surface of the milling tooth 26 by screws. The pressing plate 28 is rotatably connected to the receiving seat 21 through the rotating shaft 35. The rotating shaft 35 is fixedly connected to the upper surface of the pressing plate 28. The pressing groove 29 on the outer side of the surface of the pressing plate 28 is in the shape of a plate. The cross hole 30 on the surface of the pressing plate 28 is in the shape of a column.

[0038] When installing the milling cutter disc 11 onto the milling shank 1, first insert the insert plate 3 and the retaining block 5 into the disc groove 12 and retaining groove 13 respectively. Then, insert the threaded post 7 on the upper surface of the insert post 6 into the threaded groove 4, and insert the cross insert block 8 into the cross hole 30. Next, rotate and screw the threaded post 7 into the threaded groove 4. At the same time, the cross insert block 8 will rotate with the threaded post 7 and drive the pressure plate 28 to rotate. The pressure plate 28 drives the driven shaft 25 and the moving block 23 to move outward from the receiving groove 22 in the receiving seat 21 through the pressure groove 29, until the milling teeth 26 are fully extended to the outside of the milling cutter disc 11. Finally, the cutting insert 27 can be fixed to the surface of the milling teeth 26 with screws. This installation and operation method is convenient and quick. During the installation of the milling cutter disc 11, the milling teeth 26 can extend synchronously. When the milling cutter disc 11 is disassembled, the milling teeth 26 can be... Simultaneously, the milling cutter head 11 is stored inside, reducing the chance of the milling teeth 26 being bumped and damaged when the milling cutter head 11 is idle, thereby improving the service life of the milling cutter head 11. After the milling cutter head 11 is installed at the end of the milling shank 1, the lever 18 is moved to make the limiting plate 16 rotate with the lever 18 inside the milling cutter head 11. When the lever 18 moves to the bottom of the screw seat 14 in the lever groove 20, the limiting groove 17 on the surface of the limiting plate 16 locks the limiting post 24. Then, the clamping screw 15 is screwed into the screw seat 14 and the lower end of the clamping screw 15 is inserted into the clamping hole 19, so that the moving block 23 and the milling teeth 26 cannot move inward. This solves the problem that the teeth of the traditional milling cutter head are always exposed and may be damaged by bumping, which can make the large milling cutter head have a longer service life. Example

[0039] Please see Figures 1-10 Based on Embodiment 2, in order to allow chips to fall into the milling cutter disc 11 during milling, a chuck 9 is provided. The side of the chuck 9 is provided with an insertion hole 10 and a shield 31. The lower surface of the shield 31 is provided with a mounting base 32.

[0040] The shield 31 is fitted onto the outer surface of the pressure plate 28, while the milling teeth 26 are exposed through the slots on the surface of the shield 31. At this time, the mounting base 32 is fitted onto the outer surface of the chuck 9. The shield 31 can prevent the milling teeth 26 from loosening and shaking during machining, and can also prevent the chips generated during milling from falling into the receiving base 21. It also solves the problem that the teeth of traditional milling cutter heads are always exposed, which may lead to damage from impacts. This can give large milling cutter heads a longer service life. Example

[0041] Please see Figures 1-10In order to fix the shield 31 on the milling cutter disc 11, in addition to the third embodiment, a cylindrical insertion hole 10 is provided on the side of the clip 9. The mounting base 32 is fixedly connected to the lower surface of the shield 31. An insertion strip 33 is provided inside the side of the mounting base 32. A spring 34 is sleeved on the surface of the insertion strip 33. The insertion strip 33 is slidably connected to the side of the mounting base 32. One end of the spring 34 is fixedly connected to the side of the mounting base 32, and the other end of the spring 34 is fixedly connected to the outer end of the insertion strip 33.

[0042] When fixing the shield 31 to the milling cutter head 11, first pull the insert 33 inside the mounting base 32 outward and align the insert 33 with the insertion hole 10 on the side of the chuck 9. Then release the insert 33. Under the action of the spring 34, the insert 33 is inserted into the insertion hole 10, thereby installing the shield 31 on the outer surface of the milling cutter head 11. This solves the problem that the teeth of traditional milling cutter heads are always exposed and may be damaged by impact. It can give large milling cutter heads a longer service life. Example

[0043] Please see Figures 1-10 Based on Embodiment 4, this embodiment also provides a method for using a large milling cutter head for milling wind power equipment:

[0044] When milling wind power equipment using milling cutter disc 11, first insert disc 3 and clamping block 5 into disc groove 12 and clamping groove 13 respectively;

[0045] Next, insert the threaded post 7 into the threaded groove 4 and insert the cross-shaped insert 8 into the cross hole 30. Rotate the threaded post 7 into the threaded groove 4. At the same time, the cross-shaped insert 8 will drive the pressure plate 28 to rotate. The pressure plate 28 drives the driven shaft 25 and the milling teeth 26 at the end of the moving block 23 to extend through the pressure groove 29.

[0046] At this point, the blade 27 can be fixed to the surface of the milling tooth 26 with screws, and the milling cutter 11 can be driven by the milling shank 1 to mill the wind power equipment. This installation and operation method is convenient and quick.

[0047] When the milling cutter 11 is needed for machining operations, the milling teeth 26 can extend synchronously during the installation of the milling cutter 11. When the milling cutter 11 is disassembled, the milling teeth 26 can be synchronously retracted into the milling cutter 11 for storage, which reduces the chance of the milling teeth 26 being bumped and damaged when the milling cutter 11 is idle, thereby improving the service life of the milling cutter 11.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
