Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: A milling cutter with a chip removal groove at the end, such as... Figure 1 - Figure 5 As shown, the device includes a milling cutter body 1, a guide groove 201 that runs through the middle of the cutter teeth of the milling cutter body 1, and an outer isolation plate 3 installed on opposite sides of the milling cutter body 1. An inner isolation plate 2 is provided between the outer isolation plate 3 and the milling cutter body 1, and the inner isolation plate 2 is smaller than the outer isolation plate 3. Several rubber strips 6 are provided on the same plane as the outer isolation plate 3. The rubber strips 6 are evenly located around the inner isolation plate 2, and the rubber strips 6 are rotatably installed between the outer isolation plate 3 and the milling cutter body 1.

[0027] Firstly, the opening of the guide groove 201 in the middle of the milling cutter body 1 allows the debris generated at its end edge to flow out without affecting the normal cutting of the device. Furthermore, the cutter teeth between two adjacent guide grooves 201 are set to a normal state, providing sufficient flow space for the debris and effectively preventing debris accumulation, ensuring stable and continuous chip removal. Secondly, based on the constraint of the outer isolation disc 3 and the milling cutter body 1, and the active movement of the rubber belt 6 following the overall device, the milling cutter body 1, the inner isolation disc 2, and the outer isolation disc 3, under the centripetal force generated by the rotation of the device, keep the rubber belt 6 in a taut state, blocking and cleaning the debris flowing towards both ends of the milling cutter body 1, preventing it from entering the device connection and affecting the device's rotation efficiency. Thus, with the chip removal at the edge of the inner isolation disc 2 and the chip removal by the two ends of the rubber belt 6, the milling cutter body 1 has multi-angle sufficient chip removal performance, improving the long-term stability of the device's operation.

[0028] like Figure 1 - Figure 5 As shown, a central positioning hole 15 for positioning and guidance is provided through the middle of the milling cutter body 1. Several inner threaded grooves 4 are provided on both sides of the milling cutter body 1, and the central positioning hole 15 is located in the middle of several inner threaded grooves 4.

[0029] Both the outer isolation plate 3 and the inner isolation plate 2 have side positioning holes 14 through the middle, and the outer side of the inner isolation plate 2 has several outer threaded grooves 5, which are opened on the side surface of the outer isolation plate 3 near the milling cutter body 1.

[0030] The side positioning holes 14 on both sides are connected to the center positioning hole 15, and the inner thread grooves 4 on both sides and the outer thread grooves 5 on both sides are located in corresponding positions.

[0031] With the simultaneous positioning and fastening of the side positioning holes 14 and the central positioning hole 15, the accuracy during installation and use is ensured. At the same time, based on the isolation of the inner plate 2 itself, the debris can flow through the space between the milling cutter body 1 and the outer plate 3, and the flow of debris is limited to ensure reliable debris cleaning. Meanwhile, the combined use of the outer threaded grooves 5 and the inner threaded grooves 4 on both sides ensures the stability of the installation position of the central rubber belt 6 and improves its operational accuracy.

[0032] Example 2: A milling cutter with a chip removal groove at the end, such as... Figure 1 - Figure 5 As shown, a ring cylinder 7 is inserted into the middle of the rubber belt 6, and isolation rings 13 for limiting are installed on opposite sides of the ring cylinder 7. A support rod 8 is inserted through the middle of the isolation outer disc 3 and the isolation rings 13.

[0033] The support rod 8 is equipped with fastening bolts 9 at both ends. One end of the fastening bolt 9 is threaded with a fastening nut 12 on the outside, and the fastening bolt 9 on this side is threaded with the inner wall of the inner thread groove 4.

[0034] The other end of the fastening bolt 9 is threadedly connected to an adjusting nut 10 and a fastening threaded sleeve 11, and the fastening threaded sleeve 11 is threadedly connected to the inner wall of the outer threaded groove 5.

[0035] When installing and using the rubber belt 6, first rotate the fastening nut 12 to the outside of the fastening bolt 9, then connect and fix the fastening bolt 9 to the inner threaded groove 4, then rotate the fastening nut 12 to further limit the position between the fastening bolt 9 and the inner threaded groove 4, then rotate the adjusting nut 10 and the fastening threaded sleeve 11 to connect them to the fastening bolt 9 on the other side, then insert the fastening threaded sleeve 11 into the outer threaded groove 5, then rotate the adjusting nut 10 again to tighten the fastening threaded sleeve 11, the fastening bolt 9, and the outer threaded groove 5. Based on the rotational support of the ring cylinder 7 for the rubber belt 6, the rotational support of the support rod 8 for the ring cylinder 7, and the limiting of the adjusting nuts 10 and the fastening nut 12 on both sides by the isolation rings 13 on both sides, the rubber belt 6 can rotate accurately and stably under the positioning of the components on both sides.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
