Description

TECHNICAL FIELD

[0001] The present application belongs to the field of mechanical processing, and particularly relates to a blade and a tool. BACKGROUND

[0002] The square shoulder milling blade used in the mechanical processing industry does not have a down-drilling function. When down-drilling of a workpiece is required, an additional drill bit is usually prepared, and the milling cutter is replaced with the drill bit to achieve down-drilling. However, during the tool replacement process, time is required for tool replacement, and the tool setting operation needs to be performed again, which leads to problems such as increased tool cost, prolonged processing time, and poor processing precision.

[0003] At present, the tool with milling and drilling functions cannot perform planar milling processing on the workpiece, and the milling function is not accurate. The patent with the publication number CN118905295A proposes a composite tool applied to deep-sea pipeline cutting operation. The tool has the functions of drilling, milling, and chamfering. The tool comprises a drill bit, an end mill, a tapper, and a shank. The front part of the tool is the drill bit, which is used for drilling through the pipeline. The middle part of the tool is the wavy blade end mill, which is used for cutting off the pipeline. The wavy blade end mill has wavy blade teeth, which can effectively cut the pipeline, reduce the milling force during milling, improve the milling stability, and have good chip dividing capacity. The tail part of the tool is composed of the tapper, which is used for chamfering the pipeline after cutting off the pipeline. The shank is the connecting part of the tool, which is used for connecting with the machine tool. The compact and integrated structure of the entire tool effectively combines the drill bit, the end mill, and the tapper together, saves the tool replacement time during pipeline maintenance, simplifies the process steps, and effectively improves the operation efficiency and cutting quality.

[0004] The tool mentioned in the above patent can only be used to drill the pipeline and then mill the wall of the pipeline, and cannot complete the milling of a plane. CONTENT OF THE UTILITY MODEL

It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0037] Based on this, the application provides a blade and a tool. First, the blade provided by the embodiments of the application is introduced below.

[0038] Figure 1 A structural schematic diagram of the blade provided by an embodiment of the application is shown, Figure 2 Another structural schematic diagram of the blade provided by an embodiment of the application is shown, Figure 3 Still another structural schematic diagram of the blade provided by an embodiment of the application is shown, Figure 4 Still another structural schematic diagram of the blade provided by an embodiment of the application is shown. As Figures 1-4 shown, the blade can include the following structure:

[0039] The blade 100 includes a plurality of blade bodies 110, each blade body 110 is connected to each other and is arranged symmetrically about a central axis;

[0040] The inner surface of the blade body 110 is inclined to the outer surface of the blade body 110 to form a drilling processing edge 111 at the intersection of the bottom surface and the inner surface of the blade body 110, and the inner surface is inclined to the outer surface to form a milling processing edge 112 at the intersection of the side surface and the inner surface of the blade body 110, the edge of the drilling processing edge 111 is arranged in a horizontal direction, and the edge of the milling processing edge 112 is arranged in a vertical direction, the horizontal direction and the vertical direction are perpendicular to each other.

[0041] The blade 100 can be clamped by a mechanical arm through a tool bar, and then drilling, milling and other operations are performed on the workpiece. In the process of drilling the blade 100 by the mechanical arm, the first surface that contacts the workpiece is the bottom surface of the blade body 110, and in the process of milling, the surface that contacts the workpiece is the side surface of the blade body 110. In the blade body 110, the surface close to the plurality of blades 100 is the inner surface of the blade body 110, and the surface opposite to the inner surface is the outer surface of the blade body 110.

[0042] The inner surface of the blade body 110 is inclined to the outer surface, so that the edge of the inner surface of the blade body 110 can form an edge for cutting the workpiece. Specifically, the edge formed at the intersection of the bottom surface and the inner surface is the drilling processing edge 111, and the edge formed at the intersection of the side surface and the inner surface is the milling processing edge 112.

[0043] Since the number of the cutter bodies 110 is multiple, the drilling machining edges 111 are located at the bottom of the cutter bodies 110, and the edge parts are arranged in the horizontal direction, and the multiple cutter blades 100 are arranged in the central axis symmetry around the central axis (cutter bar) of the mechanical arm, the multiple drilling machining edges 111 are also arranged in the central axis symmetry, therefore, when the mechanical arm operates the cutter blade 100 to rotate, the multiple drilling machining edges 111 will also rotate around the central axis, so that the drilling machining edges 111 can cut into the workpiece and gradually form a hole, and the horizontal arrangement of the drilling machining edges 111 makes the bottom of the hole formed after drilling more flat, which is beneficial to maintaining the consistency of the hole diameter and the accuracy of the depth during the drilling process. Moreover, since the multiple cutter bodies 110 are arranged in the central axis symmetry, the drilling machining edges 111 can maintain balance during the rotation process, ensuring the stability and accuracy of the drilling process.

[0044] The milling machining edges 112 are located at the side surface of the cutter body 110, and the edge parts are arranged in the vertical direction. When the cutter blade 100 rotates and moves along the surface of the workpiece, the milling machining edges 112 can mill the workpiece material to realize the milling function, and the vertical arrangement of the edge parts of the milling machining edges 112 also makes the milling of the workpiece surface more flat; by outwardly inclining the inner surface of the cutter body 110, the milling machining edges 112 can better adapt to the workpiece surface during the milling process, improving the milling efficiency and processing quality. Preferably, the rotation direction of the central axis is consistent with the inclination direction of the inner surface, so that the milling machining edges 112 can better cut into the surface of the workpiece. Thus, the cutter blade 100 includes multiple cutter bodies 110, each of which can mill and drill the workpiece, thereby improving the efficiency of the cutter blade 100 in milling and drilling.

[0045] In the present application, the vertical direction refers to the direction in which the cutter contacts the workpiece for drilling, and the horizontal direction is perpendicular to the vertical direction.

[0046] In an example, the drilling machining edge 111 comprises a first segment drilling machining edge 111a and a second segment drilling machining edge 111b connected with each other, the first segment drilling machining edge 111a is connected with the milling machining edge 112, and in the vertical direction, the second segment drilling machining edge 111b is arranged to be inclined away from the bottom surface of the tool body 110. Specifically, by arranging the drilling machining edge 111 into two first segment drilling machining edges 111a and second segment drilling machining edges 111b connected with each other, and in the vertical direction, the second segment drilling machining edge 111b is arranged to be inclined away from the bottom surface of the tool body 110, so that in the process of contacting the workpiece to complete drilling by the first segment drilling machining edge 111a, in the vertical direction, the second segment drilling machining edge 111b and the surface of the workpiece form a gap, so that the debris generated in the drilling process can be discharged from the second segment drilling machining edge 111b, thereby reducing the possibility of debris adhering to the surface of the workpiece, reducing the probability of processing precision decline and workpiece surface quality deterioration, and timely removing debris can reduce the friction between the drilling machining edge 111 and the debris, reduce the wear rate of the milling machining edge 112, thereby prolonging the service life of the tool body 110, etc.

[0047] Specifically, in an example, in the horizontal direction, the second segment drilling machining edge 111b is arranged to be inclined away from the inner surface. Similarly, in the horizontal direction, the second segment drilling machining edge 111b is arranged to be inclined away from the inner surface, so that the second segment drilling machining edge 111b forms a gap with the surface of the workpiece in the horizontal direction and the vertical direction, thereby facilitating the discharge of debris, thereby better reducing the friction between the drilling machining edge 111 and the debris, reducing the wear rate of the milling machining edge 112, thereby prolonging the service life of the tool body 110, etc.

[0048] More specifically, each first segment drilling machining edge 111a is arranged to be staggered, and by arranging the first segment drilling machining edges 111a in the plurality of tool bodies 110 to be staggered, the possibility of interference between the first segment drilling machining edges 111a in each tool body 110 can be reduced, facilitating the tool body 110 to process the workpiece.

[0049] Figure 4 Another structural schematic diagram of the insert provided by an embodiment of the present application is shown, as Figure 4As shown, in an example, the rear face of the milling processing edge 112 comprises a first milling rear face 112a and a second milling rear face 112b connected to each other, the first milling rear face 112a and the second milling rear face 112b form a first obtuse angle, and the first milling rear face 112a and the inner face are connected. The rear face refers to the face that interacts with and is opposite to the processed surface on the workpiece, specifically, the rear face of the milling processing edge 112 is provided as two first milling rear faces 112a and second milling rear faces 112b connected to each other, and since a first obtuse angle is formed between the first milling rear face 112a and the second milling rear face 112b, so that during the milling operation of the workpiece by the milling processing edge 112, the chips can be discharged at the second milling processing surface, reducing the possibility of chips adhering to the surface of the workpiece, reducing the probability of processing precision decline and workpiece surface quality deterioration, and timely removing the chips can reduce the friction between the milling processing edge 112 and the chips, reduce the wear rate of the milling processing edge 112, thereby prolonging the service life of the tool body 110, etc.

[0050] Optionally, in an example, the tool body 110 is provided with a fixed hole 113 penetrating the inner face and the outer face. By providing the fixed hole 113 penetrating the inner face and the outer face of the tool body 110, the tool bar can fix a plurality of tool bodies 110 through the fixed hole 113, thereby improving the stability of the tool blade 100 when processing the workpiece.

[0051] Optionally, in an example, the outer face of the tool body 110 is provided with a cooling groove 114. By providing the cooling groove 114 on the outer face of the tool body 110, the cooling liquid can flow along the cooling groove 114 to the drilling processing edge 111 and the milling processing edge 112,

[0052] Embodiment 2:

[0053] The number of tool bodies 110 is two, and the fixed holes 113 of the two tool bodies 110 are concentrically arranged; the fixing member sequentially penetrates the fixed holes 113 of each tool body 110, and respectively connects the inner faces of the two tool bodies 110 to each other. By concentrically arranging the fixed holes 113 of the two tool bodies 110, the tool bar and the tool blade 100 can be fixed together by sequentially penetrating the two fixed holes 113 with the fixing member, thereby realizing the operation of the tool blade 100 by the mechanical arm.

[0054] In an example, the two tool bodies 110 are integrally arranged. By integrally arranging the two tool bodies 110, the structural strength of the tool body 110 is improved, and the service life of the tool body 110 is prolonged.
