[0050] Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0051] Please refer to Figure 1 and Figure 2 The present invention provides a cutting tool comprising: a crushing blade body 1 and a cutting body 2. The first end of the crushing blade body 1 is used to connect to a variable amplitude rod 4. The second end of the crushing blade body 1 has a first positioning surface 11 and a first mating surface 12. The cutting body 2 has a second mating surface 22 that mates with a second positioning surface 21 and a first mating surface 12. At least a portion of the first positioning surface 11 and the second positioning surface 21 are in contact with each other and both are inclined relative to the axial direction of the crushing blade body 1.
[0052] Please refer to Figures 3-6 Since the first positioning surface 11 and the second positioning surface 21 are inclined, and in combination with the first mating surface 12 and the second mating surface 22, the radial movement of the crushing blade 1 and the cutting body 2 is restricted in the radial direction, thereby achieving radial positioning between the crushing blade 1 and the cutting body 2, ensuring their coaxiality, ensuring assembly accuracy, and ensuring precise tool positioning, thus improving the processing quality of aramid paper honeycomb.
[0053] In addition, the cutting body 2 can cut the aramid paper honeycomb material, and the crushing blade 1 can crush the aramid paper honeycomb, reducing the risk of tearing, tearing, and chipping of the aramid paper honeycomb material and leaving the cut waste on the workpiece, thereby improving the processing quality of aramid paper honeycomb.
[0054] The cutting body 2 and the crushing blade 1 are made of cemented carbide or high-speed steel.
[0055] Specifically, the angles between the first positioning surface 11 and the second positioning surface 21 and the plane perpendicular to the axial direction of the crusher body 1 range from 10° to 40°. Within this range, there is sufficient radial restraint between the crusher body 1 and the cutting body 2, thereby ensuring the coaxiality between the crusher body 1 and the cutting body 2.
[0056] The first end of the crusher body 1 has a third positioning surface 13 and a third mating surface 14, both used to cooperate with the amplitude transformer 4. The flatness range of the third positioning surface 13 is 0 to 0.007 mm. The third positioning surface 13 is used to cooperate with the amplitude transformer 4 to position the relative position between the crusher body 1 and the amplitude transformer 4. The limitation on the flatness of the third positioning surface 13 can also ensure the assembly accuracy between the crusher body 1 and the amplitude transformer 4, thereby ensuring the assembly accuracy of the crusher body 1 and the cutting body 2 and reducing the axial displacement of the tool.
[0057] One of the crushing blade body 1 and the cutting body 2 is provided with a first insertion part 23, and the other is provided with a first insertion hole part 15. The first insertion part 23 is inserted into the first insertion hole part 15. A first mating surface 12 is formed on one of the first insertion part 23 and the first insertion hole part 15, and a second mating surface 22 is formed on the other.
[0058] The first end of the crusher body 1 is provided with a second insertion hole for insertion into the second insertion part on the amplitude rod 4, or the first end of the crusher body 1 is provided with a second insertion part 16 for insertion into the second insertion hole 45 on the amplitude rod 4. The inner circumferential surface of the second insertion hole on the crusher body 1 or the outer circumferential surface of the second insertion part 16 on the crusher body 1 is the third mating surface 14.
[0059] In this embodiment, the first insertion part 23 is disposed on the cutting body 2, and the first insertion hole part 15 is disposed on the crushing blade body 1. The first insertion part 23 is cylindrical, and the first insertion hole part 15 is a hole corresponding to the first insertion part 23. The second mating surface 22 is the outer peripheral surface of the first insertion part 23, and the first mating surface 12 is the inner wall of the hole of the first insertion hole part 15. The tolerance of the first insertion part 23 is -0.005mm to -0.014mm, and the tolerance of the first insertion hole part 15 is 0 to 0.015mm. By improving the tolerance, the assembly accuracy of the crushing blade body 1 and the cutting body 2 can be ensured, achieving an assembly accuracy of coaxiality within ±0.03mm, thereby improving the processing quality of aramid paper honeycomb.
[0060] In other embodiments, the first end of the crusher body 1 is provided with a second insertion portion, and the amplitude transformer 4 is provided with a second insertion hole portion; or the first end of the crusher body 1 is provided with a second insertion hole portion, and the amplitude transformer 4 is provided with a second insertion portion. The second insertion portion is inserted into the second insertion hole portion, and the outer peripheral surface of the second insertion portion mates with the inner peripheral surface of the second insertion hole portion, that is, the outer peripheral surface of the second insertion portion is a third mating surface, and the inner peripheral surface of the second insertion hole portion is a fourth mating surface. The tolerance of the outer diameter of the second insertion portion is -0.005mm to -0.014mm, and the tolerance of the inner diameter of the second insertion hole portion is 0 to 0.015mm. In one embodiment, the first end of the crusher body 1 is provided with a mating portion protruding from the end face of the first end. The mating portion is the second insertion portion, and the outer diameter of the second insertion portion is smaller than the outer diameter of the end face. At least part of the end face is a third positioning plane, so that the crusher body 1 can be inserted into the amplitude transformer 4, so that the crusher body 1 can be positioned and mated with the amplitude transformer 4. The specific mating is described in the following content and will not be repeated here. The two ends of the crushing blade 1 are provided with the same fitting tolerance as the amplitude rod 4 and the cutting body 2. The two ends of the crushing blade 1 are also provided with positioning surfaces that respectively cooperate with the amplitude rod 4 and the cutting body 2, thereby ensuring the coaxiality among the amplitude rod 4, the crushing blade 1 and the cutting body 2, and can efficiently improve the transmission of ultrasonic vibration, so that the amplitude can be effectively transmitted to the cutting body 2.
[0061] The crusher body 1 is equipped with a hollow structure 17. The hollow structure 17 extends through the first and second ends of the crusher body 1, which can reduce the weight of the tool, reduce ultrasonic transmission loss, and increase transmission efficiency, so that the ultrasonic waves of the amplitude rod 4 can be efficiently transmitted to the cutting body 2 and the crusher body 1.
[0062] The wall thickness of the crushing blade 1 at the hollow structure 17 is t mm, and the outer diameter of the crushing blade 1 at the hollow structure 17 is D mm, satisfying: t=D / 10, and 2.5≤t≤3. This design allows the crushing blade 1 to meet its own strength requirements while reducing ultrasonic transmission loss and improving transmission efficiency.
[0063] The wall thickness t1 of the section of the crusher body 1 near the cutting body 2 can also be set to be less than the wall thickness t2 of the section away from the cutting body 2. The wall thickness t1 of the section of the crusher body 1 near the cutting body 2 ranges from 2.5mm to 3mm, and the thickness t1 and diameter D of this section satisfy t1 = D / 10. The wall thickness t2 of the section of the crusher body 1 away from the cutting body 2 ranges from 4mm to 5mm, and the crusher body 1 is provided with cutting edges in both sections.
[0064] In this embodiment, the cutting body 2 is a circular blade. The maximum outer diameter of the cutting body 2 is greater than the maximum outer diameter of the crushing blade body 1, and the difference between the two ranges from 0.5mm to 2mm.
[0065] With this structure, the cutting body 2 can smoothly cut the aramid paper honeycomb material. Furthermore, the inclined setting of the second positioning surface 21 on the cutting body 2 can also limit the crushing blade 1. The crushing blade 1 breaks the aramid paper honeycomb material. Under the combined action of the crushing blade 1 and the cutting body 2, the processing efficiency and processing quality of the aramid paper honeycomb are improved.
[0066] The cutting body 2 has a first clearance 25 at the end opposite to the crushing blade 1. A groove 18 is provided on the circumferential surface of the crushing blade 1, and several spirally extending cutting blades are provided on the groove wall of the groove 18. A chip-breaking groove 19 is provided between adjacent cutting blades. Several chip-breaking grooves 19 are provided on a plane surrounding and perpendicular to the axial direction on the crushing blade 1, dividing the cutting blades into several cutting teeth. The second end has a second clearance 48 connecting the first positioning surface 11 and the first mating surface 12. The diameter of the second clearance 48 is larger than the diameter of the first mating surface 12. Because the second positioning surface 21 and the second mating surface 22 of the disc-shaped cutting body 2 have an arc-shaped corner at their connection, the second clearance 48 can prevent interference between the crushing blade 1 and the corner, allowing the crushing blade 1 and the cutting body 2 to be smoothly assembled and connected.
[0067] The first clearance section 25 is equivalent to the structure of the cutting body 2 being recessed inward, which can avoid the surface of the aramid paper honeycomb.
[0068] The blade groove 18 can guide the waste material out of the machine, and the chip breaking groove 19 can cut the aramid paper honeycomb material in the axial direction of the crushing blade 1 and crush it into small pieces, not powder, so that the waste material can be discharged.
[0069] Multiple cutter grooves 18 are provided and evenly arranged on the circumference of the crushing cutter body 1. The cutter grooves 18 are spiral in shape and the spiral angle ranges from 20° to 50°. The groove depth of the cutter grooves 18 ranges from 1.7mm to 9mm. In this embodiment, 25 cutter grooves 18 are provided.
[0070] On a plane perpendicular to the axial direction of the breaker body 1, there are 19 sets of chip breaking grooves on each cutting edge, and the 19 sets of chip breaking grooves surround the breaker body 1. The groove depth of the chip breaking groove 19 ranges from 0.2mm to 1.8mm, the groove width of the chip breaking groove 19 ranges from 0.3mm to 1.5mm, and the interval between two adjacent chip breaking grooves 19 on the same cutting edge ranges from 0.5mm to 2.0mm.
[0071] With this structure, multiple sets of chip-breaking grooves 19 are set up, and the relevant dimensions of the chip-breaking grooves 19 are defined to improve the efficiency of crushing aramid paper honeycomb materials and also improve the efficiency of waste discharge.
[0072] Please refer to Figure 2 and Figure 7 The cutting tool also includes a connector 3, which is used to connect the cutting body 2 and the amplitude rod 4. The cutting body 2 is provided with a first mounting hole 24, which penetrates the cutting body 2 axially. The crushing blade 1 is provided with a hollow structure 17, and the connector 3 passes through the first mounting hole 24 and the hollow structure 17.
[0073] In this embodiment, the connector 3 is a bolt. The connector 3 installs the cutter on the amplitude rod 4, that is, the connector 3 fixes the cutting body 2 on the amplitude rod 4, and at the same time the cutting body 2 presses the crushing blade 1 against the amplitude rod 4.
[0074] The connector 3 passes through the first mounting hole 24 and through the hollow structure 17 of the crusher body 1. The axial direction of the connector 3 is parallel to the axial direction of the crusher body 1. The diameter of the portion of the connector 3 that passes through the hollow structure 17 is smaller than the inner diameter of the hollow structure 17, so that the rear end face of the cutting body 2, the outer peripheral surface of the connector 3, and the inner peripheral surface of the crusher body 1 form a vibration-damping cavity, which together with the amplitude transformer 4 forms a vibration-damping cavity. This not only reduces the weight of the crusher body 1, achieving effective weight reduction, but also avoids the waste of vibration energy, so as to effectively transmit the amplitude to the cutting body.
[0075] Please refer to Figure 1 and Figure 8 This embodiment also provides an ultrasonic processing device, including the aforementioned cutting tool and amplitude transformer 4. The ultrasonic processing device ensures assembly accuracy, precise tool positioning, and improves the processing quality of aramid paper honeycomb.
[0076] The amplitude rod 4, the crushing blade 1, and the cutting body 2 are arranged sequentially along the axial direction of the crushing blade 1. The cutting body 2 is connected to the amplitude rod 4, and the cutting body 2 and the amplitude rod 4 respectively abut against the two ends of the crushing blade 1. The amplitude rod 4 has a fourth positioning surface 41 that cooperates with the third positioning surface 13 and a fourth mating surface 42 that cooperates with the third mating surface 14.
[0077] The third positioning surface 13 and the fourth positioning surface 41 abut against each other, which is the relative position between the positioning amplitude rod 4 and the crushing blade body 1.
[0078] The crusher body 1 is provided with a second insertion part 16, and the amplitude rod 4 is provided with a second slot part 45. The second insertion part 16 is inserted into the second slot part 45. A third mating surface 14 is formed on the second insertion part 16, and a fourth mating surface 42 is formed on the second slot part 45.
[0079] In this embodiment, the second insertion part 16 is cylindrical, and the second insertion hole part 45 is a hole corresponding to the second insertion part 16. The third mating surface 14 is the outer peripheral surface of the second insertion part 16, and the fourth mating surface 42 is the inner wall of the hole in the second insertion hole part 45. The outer diameter tolerance of the second insertion part 16 is -0.005mm to -0.014mm, and the inner diameter tolerance of the second insertion hole part 45 is 0 to 0.015mm. By limiting the tolerances, the assembly accuracy of the crusher body 1 and the amplitude transformer 4 can be ensured, thereby improving the processing quality of the aramid paper honeycomb.
[0080] The amplitude rod 4 is provided with a second mounting hole 47 at one end facing the crusher body 1. The connector 3 passes through the first mounting hole 24 of the cutter body 2 and the hollow structure 17 of the crusher body 1, and is connected in the second mounting hole 47 to connect the amplitude rod 4 and the cutter body 2. At the same time, the amplitude rod 4 and the cutter body 2 abut against both ends of the crusher body 1.
[0081] The amplitude rod 4 includes a clamping section 49, an intermediate section 50 and a chip removal section 43 arranged in sequence. The clamping section 49 is located away from the end of the crusher body 1 and is used to connect the transducer.
[0082] The end of the amplitude rod 4 facing the crusher body 1 is the chip removal section 43. The outer circumferential surface of the middle section 50 of the amplitude rod 4 is provided with multiple evenly arranged spiral grooves 44. The spiral grooves 44 extend from the middle section 50 to the chip removal section 43, and the length of the chip removal section 43 is greater than 10mm. The outer diameter of the chip removal section 43 is smaller than the outer diameter of the middle section 50.
[0083] The spiral groove 44 allows a portion of the axial vibration transmitted to the amplitude rod 4 to be converted into torsional vibration, forming a composite vibration. During processing, a micro-fracture layer is generated at the material cut. Combined with the crushing cutter body 1 of the hollow structure 17, it reduces cutting resistance and temperature, reduces tool wear, and increases tool life. The vibration amplitude is larger, the milling force is stable, the material removal rate is high, and the milling quality is good. It can improve defects such as tearing, cell deformation, and burrs during the processing of aramid paper honeycomb materials.
[0084] The length of the spiral groove 44 is set to 20mm to 30mm, the pitch is 120mm, and the groove width is 3.8mm to 4.2mm. The outer diameter of the amplitude rod 4 at the bottom of the spiral groove 44 is 11mm to 13mm. In this embodiment, six spiral grooves 44 are evenly arranged.
[0085] The clamping section 49 of the amplitude rod 4 facing away from the crusher body 1 is also provided with a flat part 46, which is a plane. The flat part 46 is a mating surface used to lock the amplitude rod 4.
[0086] Furthermore, the amplitude transformer 4 is configured in three sections. In the direction from the amplitude transformer 4 to the crusher body 1, the first section, a clamping section 49, is used to connect the transducer and to provide a flat section 46. The second section, also a clamping section 49, is provided with a spiral groove 44. The first and second sections can be constructed with cylinders of different diameters, and a transition arc is provided between them. The third section is a chip removal section 43. The second and third sections can also be constructed with cylinders of different diameters, and a 45° angle transition is provided between them. In one embodiment, the outer diameter of the chip removal section 43 is smaller than the outer diameter of the intermediate section 50 to facilitate chip discharge from the chip removal section 43.
[0087] This embodiment also provides a machine tool, including a drive device and the ultrasonic processing equipment described above. The drive device is connected to and drives the ultrasonic processing equipment, and provides kinetic energy to the ultrasonic processing equipment. By setting up the ultrasonic processing equipment, assembly accuracy and tool positioning can be ensured, thereby improving the processing quality of aramid paper honeycomb.
