Description

Technical Field

[0001] The present invention relates to the technical field of milling cutter discs, and particularly to a milling cutter disc with combined arc meshing teeth. Background Art

[0002] The main function of a milling cutter disc is to cut off a certain thickness of the surface of a metal material through rotational motion and feeding motion, so as to form the required shape, size and surface quality. Different types of blades or tools can be selected according to the processing requirements of the milling cutter disc, such as face mills, end mills, T-slot mills and meshing tooth mills, etc., to achieve processing of different shapes.

[0003] However, since the direction of the blade of the meshing tooth mill is fixed, when machining different products, different meshing tooth milling cutter discs need to be replaced to machine the products. And after the meshing tooth milling cutter disc is fixed on the lathe shaft, it is not very easy to disassemble. Because after being fixed, in order to prevent the meshing tooth milling cutter disc from shifting or falling off during rotation, extremely serious safety accidents will occur, resulting in very troublesome disassembly of the meshing tooth milling cutter disc. Therefore, a milling cutter disc with combined arc meshing teeth is needed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a milling cutter disc with combined arc meshing teeth to solve the disadvantages existing in the prior art.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: A milling cutter disc with combined arc meshing teeth, including a lathe mechanism, on the outer surface of which a milling cutter disc mechanism is arranged.

One side of the first slider is fixedly connected to a first arc-shaped telescopic rod, and the other end of the first arc-shaped telescopic rod is fixedly connected to one side inner wall of the first arc-shaped groove. The top of the first slider is fixedly connected to the bottom of the fixed disk.

[0007] As a preferred embodiment, a first arc-shaped spring is arranged on the outer surface of the first arc-shaped telescopic rod. One end of the first arc-shaped spring is fixedly connected to one side of the first slider, and the other end of the first arc-shaped spring is fixedly connected to one side inner wall of the first arc-shaped groove.

[0008] As a preferred embodiment, two second arc-shaped grooves are formed in the bottom of the second support plate. A second slider is slidably connected to the inner wall of the second arc-shaped groove. One side of the second slider is fixedly connected to a second arc-shaped telescopic rod, and the other end of the second arc-shaped telescopic rod is fixedly connected to one side inner wall of the second arc-shaped groove. The bottom of the second slider is fixedly connected to the top of the fixed disk.

[0009] As a preferred embodiment, a second arc-shaped spring is arranged on the outer surface of the second arc-shaped telescopic rod. One end of the second arc-shaped spring is fixedly connected to one side of the second slider, and the other end of the second arc-shaped spring is fixedly connected to one side inner wall of the second arc-shaped groove.

[0010] As a preferred embodiment, the lathe mechanism includes a shaft rod fixed to the output end of the lathe. A fixed tube is slidably connected to the outer surface of the shaft rod, and the outer surface of the fixed tube is fixedly connected to the inner wall of the branch pipe.

[0011] As a preferred embodiment, a curved surface block is fixedly connected to the inner wall of the fixed tube. A curved surface groove adapted to the curved surface block is formed in the outer surface of the shaft rod. A chute is formed at one end of the shaft rod, and one end of the chute communicates with the curved surface groove. The outer surface of the curved surface block is slidably connected to the inner wall of the curved surface groove, and the outer surface of the curved surface block is slidably connected to the inner wall of the chute.

[0012] As a preferred embodiment, a slide hole is formed in one side of the fixed tube, and one end of the slide hole penetrates into the interior of the shaft rod. An arc-shaped plate is fixedly connected to the outer surface of the fixed tube. A threaded hole is formed in one side of the arc-shaped plate, and one end of the threaded hole communicates with the slide hole. A bolt is threadedly connected to the inner wall of the threaded hole, and the outer surface of the bolt is slidably connected to the inner wall of the slide hole.

[0013] As a preferred embodiment, a threaded groove is formed in the outer surface of the shaft rod, and a groove is formed at one end of the fixed tube. A nut is slidably connected to the inner wall of the groove, and the inner wall of the nut is threadedly connected to the outer surface of the threaded groove.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0015] 1) The present invention limits the blade through the rotating groove and the rotating rod, enabling the blade to rotate in the relevant direction along the inner wall of the rotating groove. Then, the blade is limited by the first support plate and the second support plate. The first card slots and the second card slots opened on the first support plate and the second support plate can accommodate the blade. Thus, when the blade rotates, it can slide into the inside of the first card slot or the second card slot. After the blade enters the inside of the first card slot, by rotating the second support plate, the bottom of the second support plate contacts the top of the blade, so that the second support plate can limit the blade. At the same time, the blade can also be limited by the first card slot. Furthermore, the blade cannot rotate. At this time, the blade faces outward. Also, when the blade enters the inside of the second card slot, rotate the first support plate so that the top of the first support plate contacts the bottom of the blade. At this time, the blade can be limited and fixed through the second card slot opened on the first support plate and the second support plate. At this time, the direction of the blade is upward. Furthermore, the direction of the blade can be adjusted. After the first card slot is separated from the blade, the first arc spring provides elastic potential energy, which can push the first support plate to rotate so that the top of the first support plate contacts the bottom of the blade. At the same time, the first arc spring can also prevent the first support plate from rotating easily. Also, when the milling cutter disc mechanism rotates, when the rotation speed is extremely high, it will not cause the first card slot to align with the rotating groove, thereby preventing the blade from rotating. At the same time, the second support plate will cause the second arc-shaped telescopic rod to contract, and then the elastic potential energy of the second arc spring will increase. When the second card slot is separated from the blade, the elastic potential energy provided by the second arc spring can push the second support plate to rotate so that the bottom of the second support plate contacts the top of the blade. At the same time, the second arc spring can also fix the second support plate. When the milling cutter disc mechanism rotates rapidly, it will not cause the second card slot on the second support plate to align with the rotating groove, so that the blade cannot rotate.

[0016] 2) The present invention aligns the sliding groove on the shaft rod with the curved surface block, then inserts the shaft rod deeply so that the curved surface block enters the inside of the curved surface groove along the sliding groove. Then, due to the curved surface setting of the curved surface groove, the shaft rod rotates to one end of the curved surface groove. Then, the shaft rod is fixed. At this time, the bolt can pass through the threaded hole and be threadedly rotated and fixed into the inside of the shaft rod. At this time, the shaft rod is fixed inside the fixed tube, and then it is fixed again through the nut. Furthermore, the structure between the shaft rod and the fixed tube is more stable, increasing the structural stability of the equipment. Description of the Drawings

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment, as Figures 1-6As shown in the figure, the present invention provides a technical solution: a milling cutter head with combined arc meshing teeth, including a lathe mechanism 1. A milling cutter head mechanism 2 is arranged on the outer surface of the lathe mechanism 1. The milling cutter head mechanism 2 includes a branch pipe 21. A fixed disk 22 is fixedly connected to the outer surface of the branch pipe 21. A plurality of rotating grooves 23 are formed on the outer surface of the fixed disk 22. A blade 24 is rotatably arranged on the outer surface of the rotating groove 23. A rotating hole 26 is formed on one side of the blade 24. A rotating rod 25 is rotatably connected to the inner wall of the rotating groove 23. The outer surface of the rotating rod 25 is fixedly connected to the inner wall of the rotating hole 26. The outer surface of the branch pipe 21 is provided with a first support plate 27 and a second support plate 28. A fixing hole is formed at the bottom of the first support plate 27. One end of the fixing hole fixedly penetrates through to the top of the second support plate 28. The first support plate 27 is rotatably connected to the outer surface of the branch pipe 21 through the fixing hole. The second support plate 28 is rotatably connected to the outer surface of the branch pipe 21 through the fixing hole. A plurality of first clamping grooves 29 adapted to the rotating grooves 23 are formed on the top of the first support plate 27. A plurality of second clamping grooves 210 adapted to the rotating grooves 23 are formed on the outer surface of the second support plate 28. The outer surface of the blade 24 is slidably connected to the inner wall of the first clamping groove 29. The outer surface of the blade 24 is slidably connected to the inner wall of the second clamping groove 210.

[0030] Through the above embodiments, the blade 24 is limited by the rotating groove 23 and the rotating rod 25, so that the blade 24 can rotate in the relevant direction on the inner wall of the rotating groove 23. Then, the blade 24 is limited by the first support plate 27 and the second support plate 28. The first clamping grooves 29 and the second clamping grooves 210 formed on the first support plate 27 and the second support plate 28 can accommodate the blade 24. Thus, when the blade 24 rotates, it can slide into the inside of the first clamping groove 29 or the second clamping groove 210. After the blade 24 enters the inside of the first clamping groove 29, by rotating the second support plate 28, the bottom of the second support plate 28 contacts the top of the blade 24, so that the blade 24 can be limited by the second support plate 28. At the same time, the blade 24 can also be limited by the first clamping groove 29. Furthermore, the blade 24 cannot rotate. At this time, the blade 24 faces outward. At the same time, after the blade 24 enters the inside of the second clamping groove 210, rotate the first support plate 27 so that the top of the first support plate 27 contacts the bottom of the blade 24. At this time, the blade 24 can be limited and fixed by the second clamping groove 210 formed on the first support plate 27 and the second support plate 28. At this time, the direction of the blade 24 is upward. Furthermore, the direction of the blade 24 can be adjusted.

[0031] Two first arc-shaped grooves 211 are formed on the top of the first support plate 27. A first slider 212 is slidably connected to the inner wall of the first arc-shaped groove 211. A first arc-shaped telescopic rod 213 is fixedly connected to one side of the first slider 212. The other end of the first arc-shaped telescopic rod 213 is fixedly connected to one side inner wall of the first arc-shaped groove 211. The top of the first slider 212 is fixedly connected to the bottom of the fixed disk 22.

[0032] Wherein, a first arc-shaped telescopic rod 213 is provided with a first arc-shaped spring 214 on its outer surface. One end of the first arc-shaped spring 214 is fixedly connected to one side of the first slider 212, and the other end of the first arc-shaped spring 214 is fixedly connected to one side inner wall of the first arc-shaped groove 211;

[0033] Furthermore, two second arc-shaped grooves 215 are formed at the bottom of the second support plate 28. A second slider 216 is slidably connected to the inner wall of the second arc-shaped groove 215. One side of the second slider 216 is fixedly connected to a second arc-shaped telescopic rod 217. The other end of the second arc-shaped telescopic rod 217 is fixedly connected to one side inner wall of the second arc-shaped groove 215. The bottom of the second slider 216 is fixedly connected to the top of the fixed disk 22;

[0034] Wherein, a second arc-shaped spring 218 is provided on the outer surface of the second arc-shaped telescopic rod 217. One end of the second arc-shaped spring 218 is fixedly connected to one side of the second slider 216, and the other end of the second arc-shaped spring 218 is fixedly connected to one side inner wall of the second arc-shaped groove 215;

[0035] Through the above embodiments, the first support plate 27 and the second support plate 28 are stable with each other through the fixing holes and the structure of the branch pipe 21. Then, the first arc-shaped groove 211 and the second arc-shaped groove 215 are fixed to the fixed disk 22 through the first slider 212 and the second slider 216. At this time, the first support plate 27 and the second support plate 28 can be made to adhere to the fixed disk 22 as much as possible. At the same time, the first arc-shaped telescopic rod 213 and the first arc-shaped spring 214 provide elastic potential energy. In the application, when the first clamping groove 29 is separated from the blade 24, the elastic potential energy provided by the first arc-shaped spring 214 can push the first support plate 27 to rotate, so that the top of the first support plate 27 contacts the bottom of the blade 24. At the same time, the first arc-shaped spring 214 can also prevent the first support plate 27 from rotating easily. At the same time, when the milling cutter head mechanism 2 rotates, when the rotation speed is extremely high, it will not cause the first clamping groove 29 to align with the rotating groove 23, so as to prevent the blade 24 from rotating. At the same time, the second support plate 28 will cause the second arc-shaped telescopic rod 217 to contract, and then the elastic potential energy of the second arc-shaped spring 218 will increase. When the second clamping groove 210 is separated from the blade 24, the elastic potential energy provided by the second arc-shaped spring 218 can push the second support plate 28 to rotate, so that the bottom of the second support plate 28 contacts the top of the blade 24. At the same time, the second arc-shaped spring 218 can also fix the second support plate 28. When the milling cutter head mechanism 2 rotates rapidly, it will not cause the second clamping groove 210 on the second support plate 28 to align with the rotating groove 23, so that the blade 24 cannot rotate;

[0036] The lathe mechanism 1 includes a shaft rod 12 fixed to the output end of the lathe. A fixed pipe 11 is slidably connected to the outer surface of the shaft rod 12. The outer surface of the fixed pipe 11 is fixedly connected to the inner wall of the branch pipe 21;

[0037] Further, a curved surface block 13 is fixedly connected to the inner wall of the fixed pipe 11. A curved surface groove 14 adapted to the curved surface block 13 is formed on the outer surface of the shaft rod 12. A chute 15 is formed at one end of the shaft rod 12. One end of the chute 15 communicates with the curved surface groove 14. The outer surface of the curved surface block 13 is slidably connected to the inner wall of the curved surface groove 14, and the outer surface of the curved surface block 13 is slidably connected to the inner wall of the chute 15;

[0038] Further, a sliding hole 110 is formed on one side of the fixed pipe 11. One end of the sliding hole 110 penetrates into the interior of the shaft rod 12. An arc-shaped plate 18 is fixedly connected to the outer surface of the fixed pipe 11. A threaded hole 19 is formed on one side of the arc-shaped plate 18. One end of the threaded hole 19 communicates with the sliding hole 110. A bolt 111 is threadedly connected to the inner wall of the threaded hole 19, and the outer surface of the bolt 111 is slidably connected to the inner wall of the sliding hole 110;

[0039] Further, a threaded groove 16 is formed on the outer surface of the shaft rod 12. A groove 112 is formed at one end of the fixed pipe 11. A nut 17 is slidably connected to the inner wall of the groove 112, and the inner wall of the nut 17 is threadedly connected to the outer surface of the threaded groove 16;

[0040] In the above embodiment, during use, the chute 15 on the shaft rod 12 is aligned with the curved surface block 13, and then the shaft rod 12 is inserted deeply so that the curved surface block 13 enters the interior of the curved surface groove 14 along the chute 15. Then, through the curved surface setting of the curved surface groove 14, the shaft rod 12 is rotated to one end of the curved surface groove 14. Then, the shaft rod 12 is fixed. At this time, the bolt 111 can pass through the threaded hole 19 and is threadedly rotated and fixed into the interior of the shaft rod 12. At this time, the shaft rod 12 is fixed inside the fixed pipe 11, and then it is fixed again by the nut 17. Furthermore, the structure between the shaft rod 12 and the fixed pipe 11 can be made more stable, increasing the structural stability of the device.

[0041] Working principle: As Figures 1-6As shown, during use, the direction of the blade 24 is adjusted according to different requirements. When the blade 24 needs to face outward, the blade 24 is inserted into the first card slot 29. Specifically, the first support plate 27 can be rotated to align the first card slot 29 on the first support plate 27 with the rotating slot 23. Then, the blade 24 can be rotated to separate from the second card slot 210. After that, all the remaining blades 24 are rotated into the first card slot 29. After the second card slot 210 is separated from the blade 24, the elastic potential energy provided by the second arc spring 218 can push the second support plate 28 to rotate, so that the bottom of the second support plate 28 contacts the top of the blade 24. At the same time, the second arc spring 218 can also fix the second support plate 28. When the milling cutter head mechanism 2 rotates rapidly, it will not cause the second card slot 210 on the second support plate 28 to align with the rotating slot 23, so that the blade 24 cannot rotate. And through the contact between the bottom of the second support plate 28 and the top of the blade 24, the blade 24 can be limited by the second support plate 28. At the same time, the blade 24 can also be limited by the first card slot 29. Thus, the blade 24 cannot rotate. At this time, the blade 24 faces outward and is fixed. When the blade 24 needs to face upward, the blade 24 is inserted into the second card slot 210. Specifically, the second support plate 28 is rotated to align the second card slot 210 with the rotating slot 23. Then, the blade 24 is rotated to separate from the first card slot 29. After that, all the remaining blades 24 are rotated into the second card slot 210. After the first card slot 29 is separated from the blade 24, the elastic potential energy provided by the first arc spring 214 can push the first support plate 27 to rotate, so that the top of the first support plate 27 contacts the bottom of the blade 24. At the same time, the first arc spring 214 can also prevent the first support plate 27 from rotating easily. At the same time, when the milling cutter head mechanism 2 rotates, when the rotation speed is extremely high, it will not cause the first card slot 29 to align with the rotating slot 23, so as to prevent the blade 24 from rotating. At this time, the top of the first support plate 27 contacts the bottom of the blade 24. The blade 24 can be limited and fixed through the second card slot 210 opened on the first support plate 27 and the second support plate 28. At this time, the direction of the blade 24 faces upward and is fixed. Thus, the direction of the blade 24 can be adjusted.

[0042] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
