[0002] In modern society, milling heads are tools whose center of rotation can be angled with the center of rotation of the spindle to machine workpieces. Originally from Europe, they are now widely used in various fields of machining, such as aerospace, automotive, and mold making, and their production has attracted widespread attention.

[0003] Currently, when changing milling cutters or milling discs on traditional milling machines, it is necessary to replace the sleeve connected to the spindle according to the size of the milling cutter or chuck. Although the drill chuck is adjustable, the adjustment range is small and cannot fully match all the milling cutter sizes that the drill machine can use. At present, it is quite troublesome to remove the sleeve from the milling machine. It is necessary to first loosen the screw on the top of the milling machine to separate the screw from the sleeve, and then knock the screw to make the sleeve fall off. Such operation steps are cumbersome.

[0004] To address the above issues, we have developed a multi-axis linkage universal milling head device. Utility Model Content

[0005] This utility model discloses a multi-axis linkage universal milling head device, which aims to solve the technical problems in the background art.

Arc-shaped blocks are provided on both sides of the main body, and arc-shaped grooves are provided inside the arc-shaped blocks.

[0008] The two ends of the arc-shaped groove are not at the same height, and the width of the arc surface of the arc-shaped groove is set to gradually decrease. In the arc-shaped groove, the width of the lower part is greater than the width of the higher part.

[0009] In a preferred embodiment, a limiting ring is slidably connected to the outer side of the main body, and two limiting blocks are symmetrically fixedly connected inside the limiting ring. The bottom of the limiting block is set as an arc surface to cooperate with the arc groove, and the locking direction of the limiting ring is opposite to the locking direction of the external thread.

[0010] In a preferred embodiment, the body is connected to a nut via an external thread.

[0011] In a preferred embodiment, the rear end of the body is connected to an installation cone handle.

[0012] In a preferred embodiment, a replacement core is movably placed inside the mounting hole. The replacement core has an internal tooth structure and a second slot that penetrates through the replacement core.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0025] This utility model discloses a multi-axis linkage universal milling head device.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a multi-axis linkage universal milling head device includes a main body 1 and a milling cutter 16. The middle part of the main body 1 is provided with an external thread 2. The main body 1 is provided with a first slot 3, which is a through structure that penetrates the main body 1. The front end of the main body 1 is provided with a mounting hole 4. Arc-shaped blocks 5 are provided on both sides of the main body 1, and arc-shaped grooves 6 are provided inside the arc-shaped blocks 5.

[0027] The two ends of the arc groove 6 are not at the same height, and the width of the arc surface of the arc groove 6 is set to gradually decrease. In the arc groove 6, the width of the lower part is greater than the width of the higher part.

[0028] In this embodiment, the external thread 2 is set to prevent it from falling off by means of a threaded connection. At the same time, the arc block 5 is also tightened by applying pressure from the outside to ensure the stability of the device. It should be noted that the rotation of the limiting ring 7 is opposite to the rotation of the external thread 2.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in a preferred embodiment, a limiting ring 7 is slidably connected to the outer side of the main body 1, and two limiting blocks 8 are symmetrically fixedly connected inside the limiting ring 7. The bottom of the limiting block 8 is set as an arc surface to cooperate with the arc groove 6, and the locking direction of the limiting ring 7 is opposite to the locking direction of the external thread 2.

[0030] In this embodiment: After the inner core is installed, the limiting ring 7 is rotated so that the bottom of the limiting block 8 inside it moves in frictional contact with the arc surface of the arc groove 6, moving from the high width position to the low width position, and gradually tightening it to achieve the purpose of clamping the inner core.

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, the body 1 is connected to a nut 10 via an external thread 2.

[0032] In this embodiment, the nut 10 is used to connect the main body 1 to ensure its stability and prevent it from falling off.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, the rear end of the main body 1 is connected to a mounting cone shank 11.

[0034] In this embodiment, the mounting cone shank 11 is connected to the rear end of the main body 1. The two work together to reduce vibration during processing and ensure transmission efficiency and processing accuracy.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a replacement core 12 is movably placed inside the mounting hole 4. The replacement core 12 has an internal tooth structure inside and a second slot 13 is formed on the replacement core 12. The second slot 13 has a through structure that penetrates the replacement core 12.

[0036] In this embodiment, after rotating the limiting ring 7, a toothed structure inside the replacement core 12 is used to prevent the objects inside from shaking, thus maintaining stability.

[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in a preferred embodiment, a second replacement core 14 is movably placed inside the first replacement core 12. The second replacement core 14 is provided with external teeth that cooperate with the first replacement core 12. A third slot 15 is provided on the second replacement core 14, and the third slot 15 has a through structure that penetrates the second replacement core 14.

[0038] In this embodiment, the internal teeth inside the first replacement core 12 and the external teeth outside the second replacement core 14 cooperate with each other and restrict each other's movement by rotating, so as to achieve the purpose of tightening.

[0039] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, the milling cutter 16 is movably connected inside the mounting hole 4, the primary replacement core 12, and the secondary replacement core 14.

[0040] In this embodiment, since the milling cutter 16 is movably connected to the mounting hole 4, the first replacement core 12 and the second replacement core 14 are tightly fitted together. When it is desired to replace the milling head inner core, different sizes of milling cutters 16 can be adapted, and the structure is stable and will not shake.

[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, the outer side of the limiting ring 7 is provided with a hole 9 for inserting or removing the force-adding rod.

[0042] In this embodiment, the device is locked by inserting the force-adding rod into hole 9 and rotating the force-adding rod.

[0043] Working principle: When you want to replace the milling head inner core, first rotate the nut 10 to move it away from the main body 1 by means of threaded connection, so that it can be loosened up and down. Then rotate the limiting block 8 inside the limiting ring 7 in the opposite direction to move it away from the arc groove 6, and quickly remove and replace the milling head inner core.

[0044] After replacement, rotate the limiting ring 7 so that the limiting block 8 inside it re-engages with the arc groove 6, and then rotate the nut 10 in the opposite direction to quickly fix the mounting hole 4, the first replacement core 12 and the second replacement core 14.

[0045] Then, by inserting the force-applying rod into hole 9 and rotating the force-applying rod, the device can be locked a second time. This installation and disassembly method can significantly improve production efficiency compared to the sleeve structure of traditional milling machines and can meet different production needs.

[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
