DETAILED DESCRIPTION

[0029] In order to make the purpose, advantages and features of the present invention more clear, the following Figures 1 to 6 The milling cutter and milling machine proposed in the utility model are further described in detail. It should be noted that the drawings are all in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0030] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0032] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0033] In the description of the present application specification and the appended claims, the terms “first”, “second”, etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0034] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0035] refer to Figure 1 , is a schematic diagram of the structure of a milling cutter provided in an embodiment of the present application, wherein the milling cutter 1 comprises: a cutter body 11, a blade 12 and a mounting hole 13, wherein the mounting hole 13 is used to mount the milling cutter 1 on a milling machine. The cutter body 11 may comprise a plurality of cutter edges 111, and at least one mounting groove 112 is provided on each cutter edge 111 along the length direction of the cutter edge 111, and the blade 12 may be mounted in the mounting groove 112. The cutter body 11 may be an integrally formed structure, and the blade 12 may be fixedly mounted in the mounting groove 112 by screws, bolts or other detachable mounting methods, so as to facilitate the replacement of the blade during subsequent maintenance.

[0036] from Figure 1 It can be seen that the positions of the mounting grooves 112 on any two opposite blade edges 111 are the same, and the positions of the mounting grooves 112 on any two adjacent blade edges 111 are different.

[0037] It should be noted that the two opposite blade edges 111 refer to the two blade edges 111 located on the cross-sectional diameter of the blade body 11. It can be further known that the number of blade edges 111 is an even number, and the mounting grooves 112 on the two blade edges 111 are at the same position, so that the positions of the blades 12 mounted on the two blade edges 111 are also the same, and when processing a workpiece, the cutting positions of the blades 12 on the two blade edges 111 are also the same. In other words, any groove in the groove to be processed will be cut by two blades 12 in turn, thereby shortening the processing time and improving the processing efficiency.

[0038] The positions of the mounting grooves 112 on any two adjacent blade edges 111 are different. Thus, when the blade body 11 rotates one circle, multiple parallel grooves can be processed, thereby further shortening the processing time, saving processing steps, and further improving processing efficiency and saving production costs.

[0039] In the present application embodiment, Figure 2The figure is a schematic diagram of the cross-sectional structure of a milling cutter body provided by an embodiment of the present application. The two blade edges 111 located on the cross-sectional diameter L-L' of the cutter body 11 can be regarded as a group of blade edges 111, and the groove bottom thickness of each group of blade edges 111 is the same. In this way, the cutting force of a single blade edge 111 can be reduced each time, and the rigidity requirement of the tool handle can be reduced, thereby prolonging the service life of the milling head and the tool handle.

[0040] from Figure 1 As can be seen in the figure, a chip removal groove 113 is formed between any two adjacent blade edges 111 for removing chips generated by milling.

[0041] Furthermore, the bottom thicknesses of two adjacent chip grooves 113 are different. In one embodiment, the bottom thickness difference of two adjacent chip grooves 113 is 1mm-2mm. Specifically, the bottom thickness difference of two chip grooves 113 is equal to the spacing between two adjacent mounting grooves 112 on the same blade edge 111, so that different blade edges 111 can be used to process the same workpiece without repeated tool alignment, that is, two adjacent blade edges 111 can serve as further supplementary blade edges 111 to each other, so that when the workpiece structure requires more grooves, it is not limited by the length of the blade edge 111, so that only the tool handle needs to be rotated, and other blade edges 111 can continue to process more grooves.

[0042] In the embodiment of the present application, there is no limitation on the number of the blade edges 111 , and the number can be determined based on the number of grooves to be processed, the number of mounting slots 112 on each blade edge 111 , and actual needs.

[0043] In the embodiment of the present application, the number of mounting grooves 112 on each blade edge 111 can be determined according to the number of grooves that need to be processed, and the two are positively correlated. When the number of grooves that need to be processed is large, the number of mounting grooves 112 on each blade edge 111 also increases accordingly. Conversely, when the number of grooves that need to be processed is small, the number of mounting grooves 112 on each blade edge 111 also decreases accordingly.

[0044] Furthermore, the number of mounting grooves 112 on each blade edge 111 can be determined by the following formula:

[0045]

[0046] Among them, n is the number of mounting grooves on each blade edge; S is the number of grooves to be processed; N is the number of blade edges on the blade body.

[0047] In the embodiment of the present application, the position of the mounting groove 112 on each blade edge 111 is determined according to the position of the groove to be processed on the workpiece to be processed. Specifically, the position of the mounting groove 112 corresponds to the position of the groove to be processed, thereby ensuring that the corresponding groove can be processed according to production needs.

[0048] like Figure 3a As shown in the figure, it is an example of the grooves to be processed. A total of 9 grooves need to be processed. Figure 3b Taking the milling cutter shown in as an example, in one embodiment, the first blade edge 1111, as the starting blade edge, can be used to process three grooves numbered 1, 4, and 7, and the fourth blade edge 1114 opposite thereto is also used to process the three grooves numbered 1, 4, and 7; the second blade edge 1112 can be used to process three grooves numbered 2, 5, and 8, and the fifth blade edge 1115 opposite thereto is also used to process the three grooves numbered 2, 5, and 8; the third blade edge 1113 can be used to process three grooves numbered 3, 6, and 9, and the sixth blade edge 1116 opposite thereto is also used to process the three grooves numbered 3, 6, and 9.

[0049] Correspondingly, the positions of the three installation grooves on the first blade edge 1111 and the fourth blade edge 1114 for processing the three grooves numbered 1, 4, and 7 correspond to the positions of the three grooves numbered 1, 4, and 7, thereby ensuring that the three grooves can be processed after the blade is installed.

[0050] Similarly, the positions of the three mounting grooves on the second blade edge 1112 and the fifth blade edge 1115 for processing the three grooves numbered 2, 5, and 8 correspond to the positions of the three grooves numbered 2, 5, and 8, and the positions of the three mounting grooves on the third blade edge 1113 and the sixth blade edge 1116 for processing the three grooves numbered 3, 6, and 9 correspond to the positions of the three grooves numbered 3, 6, and 9.

[0051] In another embodiment, the first blade edge 1111, as the starting blade edge, can be used to process three grooves numbered 1, 2, and 3, and the fourth blade edge 1114 opposite thereto is also used to process three grooves numbered 1, 2, and 3; the second blade edge 1112 can be used to process three grooves numbered 4, 5, and 6, and the fifth blade edge 1115 opposite thereto is also used to process three grooves numbered 4, 5, and 6; the third blade edge 1113 can be used to process three grooves numbered 7, 8, and 9, and the sixth blade edge 1116 opposite thereto is also used to process three grooves numbered 7, 8, and 9. It should be noted that this embodiment does not provide a schematic diagram, but the structure of the blade edge can be easily inferred based on the above description.

[0052] Correspondingly, the positions of the three installation grooves on the first blade edge 1111 and the fourth blade edge 1114 for processing the three grooves numbered 1, 2, and 3 correspond to the positions of the three grooves numbered 1, 2, and 3, thereby ensuring that the three grooves can be processed after the blade is installed.

[0053] Similarly, the positions of the three mounting grooves on the second blade edge 1112 and the fifth blade edge 1115 for processing the three grooves numbered 4, 5, and 6 correspond to the positions of the three grooves numbered 4, 5, and 6, and the positions of the three mounting grooves on the third blade edge 1113 and the sixth blade edge 1116 for processing the three grooves numbered 7, 8, and 9 correspond to the positions of the three grooves numbered 7, 8, and 9.

[0054] The above are only two examples of the position of the mounting groove on each blade edge. The present application does not limit other possible implementation methods. It should be noted that the position of the mounting grooves on the same group of blade edges should be consistent, and the setting of the position of the mounting grooves on each group of blade edges can ensure that all grooves that need to be processed can be processed.

[0055] In the embodiment of the present application, the distance between two adjacent installation grooves 112 located on two adjacent blade edges 111 can be determined according to the distance between the grooves to be processed by each installation groove 112. Figure 3b Taking the milling cutter shown in the figure as an example, the first blade edge 1111 is provided with three mounting grooves, namely the first mounting groove 1121, the second mounting groove 1122 and the third mounting groove 1123, and the second blade edge 1112 is also provided with three mounting grooves, namely the fourth mounting groove 1124, the fifth mounting groove 1125 and the sixth mounting groove 1126. The first blade edge 1111 and the second blade edge 1112 are two adjacent blade edges, the first mounting groove 1121 and the fourth mounting groove 1124 are two adjacent mounting grooves, and the first mounting groove 1121 is used for processing Figure 3a The groove numbered 1 shown in the figure, the fourth mounting groove 1124 is used for processing Figure 3a Then, the spacing between the first mounting groove 1121 and the fourth mounting groove 1124 should correspond to the spacing between the groove numbered 1 and the groove numbered 2.

[0056] Furthermore, the spacing between two adjacent mounting grooves 112 located on two adjacent blade edges 111 can be set to be consistent with the spacing of the grooves to be processed by each mounting groove. For example, if the spacing between the two grooves is 1mm-2mm, then the spacing between the first mounting groove 1121 and the fourth mounting groove 1124 is also 1mm-2mm. However, in actual implementation, the spacing between two adjacent mounting grooves 112 on the same blade edge 111 can be set to any reasonable distance according to the structural requirements of the workpiece to be processed.

[0057] In the embodiment of the present application, when a plurality of mounting grooves 112 are provided on each blade edge 111, the distance between two adjacent mounting grooves 112 on the same blade edge 111 can be determined according to the distance between grooves to be processed by each mounting groove. Figure 3b Taking the milling cutter shown in the figure as an example, the first blade edge 11111 is provided with three mounting grooves, namely the first mounting groove 1121, the second mounting groove 1122 and the third mounting groove 1123, wherein the first mounting groove 1121 is used for processing Figure 3a The groove numbered 1 shown in the figure, the second mounting groove 1122 is used for processing Figure 3a The groove numbered 4 shown in the figure, the third mounting groove 1123 is used for processing Figure 3a Then, the spacing between the first mounting groove 1121 and the second mounting groove 1122 should correspond to the spacing between the groove numbered 1 and the groove numbered 4, and the spacing between the second mounting groove 1122 and the third mounting groove 11223 should correspond to the spacing between the groove numbered 4 and the groove numbered 7.

[0058] like Figure 4 As shown, it is a front view of a milling cutter provided in an embodiment of the present application, wherein the dimensions D and d can be adjusted according to the requirements of the parts.

[0059] In the embodiment of the present application, the shape of the blade 12 is not specifically limited, and it can be an "L"-shaped blade or an "I"-shaped blade. However, it is more preferred that Figure 5 The figure shows a schematic diagram of the structure of a "Z" type blade. Figure 5 As can be seen in the figure, the blade 12 can be a "Z"-shaped double-edged blade, so that each blade has two cutting edges, and one blade can be reused twice, which not only saves costs but also increases the service life of a single blade.

[0060] In the embodiment of the present application, the thickness of the blade can be consistent with the width of the groove to be processed, that is, when the width of the groove to be processed is 0.5mm-1.5mm, a blade with a blade thickness of 0.5mm-1.5mm can be used. In fact, blades with blades of different thicknesses can be used according to the structural requirements of the workpiece to meet the processing requirements.

[0061] In the embodiment of the present application, the angle between two adjacent blade edges 111 can be 30°-120°. For example, the angle between two adjacent milling flutes is 30°, 45°, 60°, 90° and 120°. For example, the angle between two adjacent milling flutes is 30° and each milling flute has three blades. At this time, the number of blade edges is 360° / 30°=12, that is, there are 6 groups of blade edges. In this way, the milling cutter can process 18 grooves on the same processing surface at the same time without re-calibrating the tool.

[0062] On the other hand, Figure 6 As shown, the present application also provides a structural schematic diagram of a milling machine, including: a milling machine body 2, a transmission module 3 and a fixture 4, wherein the milling machine body 2 includes a milling head 21, a tool handle 22 and the above-mentioned milling cutter 1, the milling cutter 1 is detachably mounted on the tool handle 22, and the tool handle 22 is detachably mounted on the milling head 21. The milling machine using the above-mentioned milling cutter 1 can ensure that multiple grooves can be processed simultaneously each time, thereby saving processing procedures and processing time, improving production efficiency, and further saving production costs.

[0063] It should be noted that the above Figure 6 What is shown is only an example of a milling machine. In other embodiments of the present application, the milling machine may also have other structures, which is not limited in the present application.

[0064] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
