[0045] See also Figure 1 , Figure 3 and Figure 5 , the embodiment of the present application provides a multifunctional composite tool 100, which is used to be installed on a driving device (not shown) and to process different structural features of a product 300, such as a connection hole 310, a step groove 330, and a contour surface 350, under the drive of the driving device. The driving device may be a machining center, a CNC milling machine, etc., and the product 300 may be a shell of an electronic device such as a server, a laptop computer, or a mobile phone. For ease of understanding and explanation, the embodiment of the present application takes the driving device as a machining center and the product 300 as a server shell as an example, and defines the first direction as Figure 1 The Z-axis direction is shown, and the second direction is Figure 1 In the X-axis direction shown, the first direction and the second direction are perpendicular to each other. Obviously, this is not a limitation of the embodiment of the present application.

[0046] In this embodiment, the multifunctional composite tool 100 includes a tool handle 10 and a tool head 20 , and the tool handle 10 is used to connect with a driving device.

[0047] The tool head 20 includes a drill 21, a groove repairing tool 22 and a contouring tool 23. The tool handle 10, the contouring tool 23 and the drill 21 are sequentially connected along a first direction. The groove repairing tool 22 is provided at one end of the drill 21 close to the contouring tool 23 and extends along a second direction. The drill 21 is used to process the connecting hole 310 of the product 300, the contouring tool 23 is used to process the contour surface 350 of the product 300, and the groove repairing tool 22 is used to process the step groove 330 of the product 300. Here, the first direction is the extension direction of the processing axis (not shown) of the multifunctional composite tool 100.

[0048] Specifically, the tool handle 10, the contour tool 23 and the drill 21 are coaxially arranged along the first direction. When the connecting hole 310 of the product 300 needs to be processed, the drill 21 is used to drill the corresponding position of the product 300 to form the connecting hole 310 of the product 300; when the step groove 330 of the product 300 needs to be processed, the groove repair tool 22 is used to cut the corresponding position of the product 300 to form the step groove 330 of the product 300. Figure 3 and Figure 4 As shown, when processing the step groove 330 inside the mounting hole 320 of the product 300, the drill 21 is passed through the mounting hole 320, and the groove repairing tool 22 is used to cut the inner part of the product 300 near the mounting hole 320 to form the step groove 330 inside the mounting hole 320; when it is necessary to process the contour surface 350 of the product 300, the contour knife 23 is used to cut the corresponding position of the product 300 to form the contour surface 350 of the product 300, as shown in FIG. Figure 5 As shown, when processing the contour surface 350 of the assembly notch 340 of the product 300 , the contour surface 350 of the assembly notch 340 can be formed by cutting the inner wall of the assembly notch 340 with the contour knife 23 .

[0049] Of course, in some other embodiments, the grooving tool 22 can also be used to process the step grooves 330 at other positions of the product 300, such as the step grooves 330 at the entrances of blind holes (not shown) and arc grooves (not shown). The contour knife 23 can also be used to process the contour surfaces 350 at other positions of the product 300, such as the contour surfaces 350 of elliptical holes (not shown) and rounded corners (not shown). The embodiments of the present application do not make specific limitations on this.

[0050] See also Figure 1 and Figure 2In this embodiment, the drill 21 is provided with a plurality of cutting protrusions 211 extending in the first direction and arranged at intervals along the circumferential direction, and a first chip removal groove 212 is formed between two adjacent cutting protrusions 211, respectively. The slotting tool 22 is provided at one end of one of the cutting protrusions 211 close to the contour tool 23. By providing the cutting protrusions 211, it is convenient to quickly perform drilling processing on the product 300. By forming the first chip removal groove 212 between two adjacent cutting protrusions 211, it is convenient to quickly discharge the chips formed by the cutting protrusions 211 drilling the product 300. By providing the slotting tool 22 at one end of one of the cutting protrusions 211 close to the contour tool 23, the rotation radius of the slotting tool 22 can be increased, and the first chip removal groove 212 can be blocked to avoid affecting the chip removal effect of the first chip removal groove 212.

[0051] In this embodiment, each cutting protrusion 211 is arranged at an angle, and the bottom of each first chip removal groove 212 extends from the bottom of an adjacent cutting protrusion 211 to the top of another adjacent cutting protrusion 211. In this way, the structural strength of the cutting protrusion 211 can be increased, thereby facilitating a reduction in the probability of damage to the cutting protrusion 211. In addition, the inclined cutting protrusion 211 can reduce the contact area with the product 300, thereby facilitating an improvement in the efficiency of the drill 21 in drilling the product 300 to form the connecting hole 310.

[0052] In this embodiment, each cutting protrusion 211 is provided with a drilling edge 213 extending toward the adjacent first chip groove 212 at one end away from the contour cutter 23. Specifically, the drilling edge 213 is wedge-shaped, and the drilling edge 213 is inclined from the end of the drill 21 away from the contour cutter 23 toward the side wall of the cutting protrusion 211 located in the first chip groove 212. The provision of the drilling edge 213 is conducive to improving the efficiency of the drill 21 in drilling the product 300 to form the connecting hole 310.

[0053] In this embodiment, the drill bit 21 has a drill tip 214 at one end away from the contour cutter 23. By providing the drill tip 214, the connection hole 310 can be formed without pre-drilling when processing the connection hole 310, which is beneficial to improving the efficiency of the drill bit 21 in drilling the product 300 to form the connection hole 310.

[0054] In this embodiment, the inclination angle of the drill tip 214 ranges from 110 degrees to 160 degrees. When the inclination angle of the drill tip 214 is small, the stability and feeding capacity of the drill bit 21 are poor, but non-ductile materials can be processed to reduce the probability of material collapse. When the inclination angle of the drill tip 214 is large, the stability and feeding capacity of the drill bit 21 are good, and materials with good ductility can be processed and the processing efficiency can be improved. The product 300 of this embodiment is generally made of alloy material with good ductility. The preferred inclination angle of the drill tip 214 is 130 degrees and 160 degrees.

[0055] In this embodiment, the groove repairing tool 22 is block-shaped and the width of the groove repairing tool 22 is the same as the width of the adjacent cutting protrusion 211 , which is beneficial to improve the structural strength of the groove repairing tool 22 .

[0056] In this embodiment, the end of the groove repairing tool 22 away from the adjacent cutting protrusion 211 has a first groove repairing edge 221 inclined from an adjacent first chip removal groove 212 to another adjacent first chip removal groove 212, and the side of the groove repairing tool 22 close to the contouring tool 23 has a second groove repairing edge 222 inclined toward the contouring tool 23. Figure 3 and Figure 4 As shown, when processing the step groove 330 inside the mounting hole 320 of the product 300, the first groove trimming blade 221 cuts the groove wall of the step groove 330, and the second groove trimming blade 222 cuts the groove bottom of the step groove 330. In this way, by providing the first groove trimming blade 221 and the second groove trimming blade 222, it is convenient to process the step groove 330 inside the product 300, and it is beneficial to improve the efficiency of processing the step groove 330.

[0057] In some other embodiments, the end of the groove repairing tool 22 away from the adjacent cutting protrusion 211 has a first groove repairing edge 221 inclined from an adjacent first chip removal groove 212 to another adjacent first chip removal groove 212, and the side of the groove repairing tool 22 away from the contouring tool 23 has a second groove repairing edge 222 inclined toward the end of the drill 21 away from the contouring tool 23. When processing the step groove 330 outside the mounting hole 320 of the product 300, the first groove repairing edge 221 cuts the groove wall of the step groove 330, and the second groove repairing edge 222 cuts the groove bottom of the step groove 330, so as to facilitate the processing of the step groove 330 outside the product 300 and improve the efficiency of processing the step groove 330, which is not specifically limited in the embodiment of the present application.

[0058] In this embodiment, the contour knife 23 is provided with a plurality of spiral cutting edges 231 arranged at intervals along the circumferential direction, and a second chip removal groove 232 is formed between two adjacent cutting edges 231. The spiral cutting edges 231 are provided to improve the efficiency of the contour knife 23 in cutting the contour surface 350 of the product 300, and the second chip removal groove 232 is provided to facilitate the rapid discharge of the debris formed by the contour knife 23 cutting the product 300.

[0059] In this embodiment, the number of the plurality of second chip grooves 232 is the same as the number of the plurality of first chip grooves 212, and the plurality of second chip grooves 232 correspond to the plurality of first chip grooves 212 one by one, and each second chip groove 232 is connected to the corresponding first chip groove 212. In this way, the chips formed by the drill 21 drilling the product 300 are discharged sequentially through the first chip groove 212 and the second chip groove 232, and the chips formed by the contour cutter 23 cutting the contour surface 350 of the product 300 are discharged sequentially through the second chip groove 232 and the first chip groove 212.

[0060] In this embodiment, the number of cutting protrusions 211, the first chip groove 212, the cutting edge 231 and the second chip groove 232 is three. In some other embodiments, the number of cutting protrusions 211, the first chip groove 212, the cutting edge 231 and the second chip groove 232 can also be four, five, etc., and the embodiment of the present application does not specifically limit this.

[0061] In this embodiment, the rotation radius of the drill 21 is less than or equal to the rotation radius of the contour cutter 23. Preferably, the rotation radius of the drill 21 is equal to the rotation radius of the contour cutter 23, so as to facilitate the use of the multifunctional composite tool 100 for processing.

[0062] In this embodiment, along the first direction, the size of the cross section of the end of the handle 10 close to the contour knife 23 is gradually reduced to the same size as the cross section of the contour knife 23. Specifically, the handle 10 is cylindrical, and the end of the handle 10 close to the contour knife 23 is tapered. By setting the size of the cross section of the end of the handle 10 close to the contour knife 23 to gradually reduce to the same size as the cross section of the contour knife 23, the contour knife 23 can effectively avoid interference with the handle 10 when cutting the product 300. In addition, since the diameter of other parts of the handle 10 is large, it is beneficial to improve the structural strength of the multifunctional composite tool 100.

[0063] In this embodiment, the side wall of the end of the tool handle 10 facing away from the contour knife 23 has a limiting surface 11. When the tool handle 10 is connected to the driving device, the limiting surface 11 abuts against the driving device to limit the rotation of the tool handle 10 relative to the driving device, which is beneficial to improving the accuracy of the structural features of the product 300 processed by the multifunctional composite tool 100.

[0064] In this embodiment, the tool handle 10 , the drill bit 21 , the groove cutter 22 and the contour cutter 23 are integrally formed, which is beneficial to improving the overall structural strength of the multifunctional composite tool 100 .

[0065] In summary, the multifunctional composite tool 100 of the embodiment of the present application realizes the function that a set of tools can process multiple different structural features of the product 300 by setting a drill 21, a groove repair tool 22 and a contour tool 23 to process the connecting hole 310, the step groove 330 and the contour surface 350 of the product 300 respectively, thereby reducing the number of tools used when processing multiple different structural features of the product 300, thereby reducing the tool cost. In addition, since the multifunctional composite tool 100 of the present application can process multiple different structural features of the product 300, the time spent on switching tools and tool alignment when processing multiple different structural features of the product 300 is saved, thereby improving the processing efficiency of the tool.
