[0066] In the present application, "and / or" is only a description of the association relationship of the associated objects, which means that there can be three relationships; for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0068] In order to make the purpose, technical scheme and advantages of the present application more clear and obvious, the present application is further described in detail below in combination with the drawings and examples.

[0069] For cutting tools, in the related art, one tool bar is usually equipped with one blade, and one cutting tool corresponds to one cutting method. However, in the process of machining some parts, the inventors found that cutting tools with multiple different cutting methods are needed, especially for tubular parts, the inner surface and the outer surface of the tube often need to be machined. Therefore, different cutting tools need to be frequently replaced, and different machining processes need to be adjusted and different machine tools need to be replaced to complete the machining of the entire part, which is not only complicated and time-consuming, but also very costly.

[0070] Based on this, the inventor proposes a multifunctional cutting tool which realizes multifunctional cutting machining of different cutting types or cutting methods, especially for the same part which needs different cutting methods for machining process, realizes one tool with multiple functions, reduces the replacement of cutting tools, reduces the adjustment of machine tool process and reduces the number of machine tool changes, so as to realize the one-time forming of the same part, and the cutting tool integrates a cooling channel to realize the cooling effect of each cutter on the cutting tool in the cutting process. The cutting tool is described below in combination with multiple embodiments.

[0071] Please refer to Figures 1-2 , Figure 1 The structure of the cutting tool 10 provided by the embodiment is shown, Figure 2 The cutting tool provided by the embodiment is shown along the axial direction,

[0072] As Figure 1 and Figure 2 shown, the cutting tool 10 includes a cutting handle 100, a cutting head 200 integrally formed with the cutting handle 100, at least two mounting seats spaced apart on the cutting head 200, at least two cutter assemblies, each cutter assembly being detachably connected to the corresponding mounting seat; and a cooling channel 130 at least partially disposed in the cutting head 200, wherein the cooling channel 130 includes a branch channel with the same number of mounting seats, and each branch channel is used to deliver cooling medium to the cutting edge of the corresponding cutter assembly.

[0073] It can be understood that by spacing at least two mounting seats on the cutting head 200, each mounting seat can detachably connect a cutter assembly with different cutting machining directions. When machining the same part in different machining processes, the cutter assemblies at different positions can perform cutting motion in different axial directions, so as to realize the machining of one cutting tool with multiple cutting functions of one part, reduce the frequency of replacing cutting tools and the number of replacing machine tools, thereby reducing the machining cost, and effectively cool the cutter during machining by setting the cooling channel 130.

[0074] In order to facilitate the description of each embodiment below, an XYZ three-axis rectangular coordinate system is established, the X-axis direction along the axial direction of the cutting tool is defined, the Z-axis direction along the center axis of the positioning hole is defined, and the Y-axis direction perpendicular to the plane formed by the X-axis and the Z-axis is defined. It should be understood that the X-axis direction includes the X-axis positive direction and the X-axis negative direction, and the Y-axis direction and the Z-axis direction are the same. The coordinate system of the cutting tool 10 can be flexibly set according to actual needs. This application only gives an example and cannot be considered as a special limitation of this application.

[0075] In some embodiments, the cutting head 200 has a cutting end surface 210 intersecting the x-axis, preferably perpendicular to the x-axis, and an abutment surface 220 adjacent to the cutting end surface 210. The mounting seat can include a first mounting seat 230, a second mounting seat 240, and a third mounting seat 250. The first mounting seat 230 is a hole-type mounting seat arranged inside the cutting end surface 210 and the abutment surface 220 of the cutting head 200, and can be used to mount a bar-type cutter adapted thereto. The second mounting seat 240 and the third mounting seat 250 can be slot-type mounting seats arranged at the edges of the cutting head 200, and can be used to mount a sheet-type cutter adapted thereto.

[0076] In one example, the first mounting seat 230 is used for mounting and fixing the first cutter assembly 300, the second mounting seat 240 is used for mounting and fixing the second cutter assembly 400, and the third mounting seat 250 is used for mounting and fixing the third cutter assembly 500. The first cutter assembly 300 can be a bar-type cutter, which can be used to process the inner wall of a tubular part. The second cutter assembly 400 and the third cutter assembly 500 are sheet-type cutters, which can be mounted to the corresponding mounting seat by bolts, and can be used to process the surface shape of the part.

[0077] It should be noted that the first cutter assembly 300, the second cutter assembly 400, and the third cutter assembly 500 have different cutting processing directions. For example, the second cutter assembly 400 can be used for processing along the x-axis, and the third cutter assembly 500 can be used for processing along the y-axis. The cutting edges of the first cutter assembly 300, the second cutter assembly 400, and the third cutter assembly 500 are preferably located at the same height along the z-axis. The shape of the second mounting seat 240 and the third mounting seat 250 can be designed according to the actual need of the cutter assembly to be installed, and the specific shape is not limited here.

[0078] Meanwhile, the cutting direction of the cutter assembly also needs to be considered when designing the mounting seat. Taking the second cutter assembly 400 as an example, the cutting direction of the second cutter assembly 400 is along the x-axis. Therefore, the second mounting seat 240 can be designed to be parallel to the horizontal plane of the x-y axis. In this way, the fixing strength and rigidity of the mounting seat to the cutter assembly are improved. The mounting method of the second cutter assembly 400 and the third cutter assembly 500 can be fixed by screws, or other fixing methods, which can be selected according to actual needs.

[0079] It should be noted that the cutting edge of the first tool assembly 300 protrudes from the cutting end surface 210, and the cutting edges of the second tool assembly 400 and the third tool assembly 500 protrude from the outer contour line of the cutting head 200 projected along the central axis (i.e., the X-axis direction). In addition, more mounting seats can be arranged at the edge of the cutting head 200, and more cutting tools can be mounted correspondingly. Each cutting tool can have a different cutting direction, which can be set according to actual needs, and is not limited here.

[0080] In this way, by arranging multiple mounting seats and multiple tool assemblies on the cutting head 200, the machining of the cutting tool with multiple cutting functions is realized. The second mounting seat 240 and the third mounting seat 250 are arranged at the edge of the cutting head 200, so that the second tool assembly 400 and the third tool assembly 500 protrude from the outer contour line of the cutting head 200 projected along the central axis after being mounted. Therefore, the machining of the parts is facilitated, and the cutting directions of the third tool assembly 500 and the second tool assembly 400 are arranged staggered, thereby realizing different cutting functions.

[0081] Continuing to refer to Figures 1-2 The first mounting seat 230 can include a mounting hole 231 and a positioning hole. The mounting hole 230 is arranged on the cutting end surface 210 of the cutting head 200, and the positioning hole is arranged on the abutment surface 220 of the cutting end surface 210. One end of the positioning hole extends to communicate with the mounting hole 231.

[0082] Optionally, the mounting hole 230 can be arranged inward from the cutting end surface 210 along the central axis direction of the cutting head 200, and one end of the mounting hole 230 communicates with the partial cooling channel 130 arranged on the cutting shank 100. In this way, the machining of the mounting hole 230 and the internal cooling channel 130 of the cutting tool is facilitated, and the cooling medium can be delivered to the first tool assembly 300. The shape of the mounting hole 230 can be designed according to the shape of the first tool assembly 300, for example, it can be a circular hole, and of course it can also be a square hole.

[0083] Optionally, the positioning hole is arranged on the abutment surface 220 of the cutting end surface 210, the abutment surface 220 is preferably located above the mounting hole 230, the abutment surface 220 and the cutting end surface 210 form an angle which can be a right angle or an acute angle, preferably the abutment surface 220 and the cutting end surface 210 are perpendicular to each other, in this way, it is more convenient to arrange the positioning hole on the abutment surface 220, specifically, the first positioning hole 232 and the second positioning hole 233 are arranged on the abutment surface 220 along the Z-axis at intervals, the first positioning hole 232 and the second positioning hole 233 can be located on the same straight line along the X-axis, the first positioning hole 232 and the second positioning hole 233 are in communication with the mounting hole 230, preferably the first positioning hole 232 and the second positioning hole 233 are in perpendicular communication with the mounting hole 230, in this way, the arrangement of the first positioning hole 232 and the second positioning hole 233 facilitates the installation, fixation and disassembly of the first tool assembly 300.

[0084] Of course, it can be understood that, under the premise of meeting the requirements of fixing and facilitating disassembly and replacement of the first tool assembly 300, the positioning member and the positioning hole matched therewith can also be arranged in three, four or other numbers, the central axis of the first positioning hole 232 and the second positioning hole 233 can also not be along the Z-axis, for example, the positioning hole is arranged obliquely from the abutment surface 220 to be in communication with the mounting hole 231, and the shape of the positioning hole can be designed according to the shape of the positioning member.

[0085] Please refer to Figure 3 and Figure 4 , Figure 3 shows a structure schematic view of the cutting tool along the axial direction according to the embodiment; Figure 4 shows a structure schematic view of the rod-shaped cutter 310, the first tool assembly 300 includes the rod-shaped cutter 310, the first positioning member 320 and the second positioning member 330, the shapes of the rod-shaped cutter 310, the first positioning member 320 and the second positioning member 330 can be cylindrical, one end of the rod-shaped cutter 310 partially extends into the mounting hole 230, and then the first positioning member 320 is connected with the first positioning hole 232 and the second positioning member 330 is connected with the second positioning hole 233 to fix the rod-shaped cutter 310.

[0086] Exemplarily, the first positioning member 320 and the first positioning hole 232 can be in threaded connection, the second positioning member 330 and the second positioning hole 233 can be in threaded connection or interference fit connection, the first positioning hole 232 is closer to the cutting end face 210 than the second positioning hole 233, by tightening the first positioning member 320, the bottom surface of the first positioning member 320 is abutted to the circumferential side surface of the rod-shaped cutter 310, thereby generating a downward pressing force on the rod-shaped cutter 310, and by the arrangement of the second positioning member 330, the second positioning member 330 is abutted to the preset surface of the rod-shaped cutter 310, thereby forming interference to prevent the rod-shaped cutter 310 from rotating after installation, i.e., generating a locking force on the rod-shaped cutter 310, at the same time, the arrangement of the second positioning member 330 can also realize the positioning of the rod-shaped cutter 310, so that the cutting edge of the rod-shaped cutter 310 is at a preset fixed position after installation.

[0087] In one example, referring to Figure 5 , the overall shape of the rod-shaped cutter 310 can be columnar, wherein the rod-shaped cutter 310 is provided with a cutting edge 311 at one end head for cutting processing, and is provided with a positioning surface 312 at the other end tail for installation and fixation, the positioning surface 312 can be an inclined surface intersecting with the central axis of the rod-shaped cutter 310, the included angle α formed by the positioning surface 312 and the central axis of the rod-shaped cutter 310 ranges between 0°-90°, i.e., the value range is greater than 0 degree and less than 90°, for example, α can take values of 30°, 45° or 60°, which can be selected according to actual needs, in this way, when the positioning surface 312 is abutted to the second positioning member 330 after installation of the rod-shaped cutter 310, the relative rotation with the cutting head 200 can be more effectively prevented.

[0088] Optionally, the rod-shaped cutter 310 can be replaced, for example, when different shapes need to be processed in a tubular workpiece, the rod-shaped cutter 310 with different shaped cutting edges can be replaced in advance.

[0089] It should be noted that during the installation of the rod-shaped cutter 310, the second positioning member 330 can be installed in the second positioning hole 233 first, then the rod-shaped cutter 310 is inserted into the installation hole 231 until the positioning surface 312 at the tail of the rod-shaped cutter 310 abuts against the second positioning member 330, and the rod-shaped cutter 310 cannot be inserted further, then the first positioning member 320 is inserted into the first positioning hole 232, and the first positioning member 320 is tightened to the end abutted to the side surface of the rod-shaped cutter 310, thereby completing the installation and fixation of the rod-shaped cutter 310, wherein after the installation and fixation of the rod-shaped cutter 310, the cutting edge 311 of the rod-shaped cutter 310 needs to protrude from the cutting end face 210.

[0090] Of course, the positioning surface 312 can also not be a bevel, for example, the positioning surface 312 can be an arc surface, as long as the positioning surface 312 can cooperate with the second positioning member 330 to achieve the locking installation and fixation of the rod-shaped cutter 310.

[0091] Please refer to Figure 4 and Figure 6 , Figure 6 The structure of the rod-shaped cutter provided by the embodiment is shown in the structural schematic view, and the end of the cutting shank 100 is provided with a fastening structure 110 along the axial direction, which is used to fix the cutting tool to the corresponding machine tool. The fastening structure 110 can be a sleeve shape and is fixed by a screw or a bolt, of course, it can also be other fixing modes, and the specific connection mode can be selected according to actual needs, which is not limited here. A cooling channel 130 is arranged at one end of the fastening structure 110 along the X-axis direction, and the cooling channel 130 includes a main stem channel 131 and a branch channel 132. A water inlet 120 is arranged on the side wall of the cutting shank 100 close to the cooling channel 130, and the water inlet 120 is in communication with the cooling channel 130. The water inlet 120 is used to connect the cooling pipe outside to deliver the cooling medium to the position of each cutter assembly of the cutting tool.

[0092] It should be noted that the fastening structure 110 and the cooling channel 130 are sequentially distributed along the central axis. When the cutting tool is installed, the sleeve opening of the fastening structure 110 is blocked, so that the cooling medium flows from the water inlet 120 and flows out from each branch channel 132.

[0093] Please refer to Figure 7 and Figure 8 , Figure 7 The structure of the internal cooling channel distribution of the cutting tool provided by the embodiment is shown in the structural schematic view, Figure 8 is a partial enlarged schematic view of part A in Figure 7 For Figure 7 , it should be noted that Figure 7 retains some machining holes of the machining cooling liquid channel, and these machining holes are blocked after the machining of the cooling liquid channel is completed. That is, the structure of these machining holes cannot be considered as a special limitation to the cutting tool structure of the present application. In addition, in order to facilitate description, the direction of each arrow in the figure represents the flow direction of the cooling liquid in the cooling liquid channel.

[0094] In one example, a first inclined surface 260 and a second inclined surface 270 may be provided at the position of the cutting head 200 near the second mounting base 240 and the third mounting base 250. A first outlet 261 is provided on the first inclined surface 260, and a second outlet 271 is provided on the second inclined surface 270. The branch channel 132 includes a first branch channel 1321, a second branch channel 1322, and a third branch channel 1323. One end of the first branch channel 1321, the second branch channel 1322, and the third branch channel 1323 converges and is sealed to the main channel 131. The other end of the second branch channel 1322 extends to the first outlet 261, and the other end of the third branch channel 1323 extends to the second outlet 271.

[0095] Optionally, the first inclined surface 260 and the second inclined surface 270 can be located above the second mounting base 240 and the third mounting base 250, respectively. This facilitates the spraying of the cooling medium onto the cutting edge of the corresponding tool assembly. The position of the outlet can be determined experimentally. Specifically, the positions of the first outlet 261 and the second outlet 271 need to satisfy the following condition: when the cooling medium flows out from the outlet, it can be sprayed onto the cutting edge of the corresponding tool assembly, thereby effectively cooling the tool assembly.

[0096] It is understandable that the arrangement of the first inclined surface 260 and the second inclined surface 270 facilitates the processing of the second branch channel 1322 and the third branch channel 1323, as well as the determination of the positions of the first outlet 261 and the second outlet 271.

[0097] like Figure 3 and Figure 8 As shown, a portion of the inner wall of the mounting hole 231 is recessed along the direction away from the central axis of the mounting hole to form a first branch channel 1321. One end of the first branch channel 1321 extends to the cutting end face 210, and the other end extends to communicate with the main channel 131. Thus, after the first tool assembly 300 is installed, the first branch channel 1321 can deliver the cooling medium to the cutting edge of the first tool assembly 300.

[0098] Optionally, the first branch channel 1321 is staggered from each positioning hole. On the one hand, this facilitates the machining of the first branch channel 1321 and the positioning holes. On the other hand, it avoids blockage of the first branch channel 1321 after the positioning hole is connected to the positioning component. The end of the first branch channel 1321 near the cutting end face 210 can be located on the upper surface wall of the positioning hole. This facilitates the spraying of cooling medium to the cutting edge of the first tool assembly 300, thereby achieving effective cooling of the bar tool during the cutting process.

[0099] It can be understood that the first branch channel 1321 is integrated on the mounting hole 231, which is convenient for machining and production of the cutting tool, and the cooling medium has a better cooling effect on the first cutting tool assembly 300 when flowing out. Of course, the first branch channel 1321 can also be a small hole separately formed and communicated with the main channel 131 at one end. In this way, the cooling medium can also be delivered to the cutting edge of the first cutting tool assembly 300. The specific selection can be made according to actual needs.

[0100] Please refer to Figure 9 and Figure 10 , Figure 9 shows a structure schematic diagram of the cutting tool in a machining process provided by the embodiment, Figure 10 shows a cross-sectional schematic diagram of the cutting tool in a machining process based on Figure 9 Figure 10 Figure 9 A-A direction, the machining workpiece 20 is a tubular workpiece to be machined, and the first cutting tool assembly 300 can be used to process the inner groove 23 by extending into the lumen of the machining workpiece 20 during the machining process of the cutting tool 10. Of course, other shapes can also be processed in the lumen, and the first cutting tool assembly 300 can also be replaced by a rod-shaped tool with different cutting modes. The second cutting tool assembly 400 can cut along the a direction, for example, the end face chamfering 21 of the machining workpiece 20 can be machined based on the second cutting tool assembly 400. The third cutting tool assembly can cut along the b direction, for example, the outer groove 22 of the end face of the machining workpiece 20 can be machined based on the third cutting tool assembly 500.
