Description

Technical Field

[0001] This invention relates to the field of hole-making technology for metal materials, and in particular to a cutting tool, apparatus and method for processing metal honeycomb sandwich materials. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Metallic honeycomb sandwich structures are laminated composite materials made by bonding upper and lower skins and a lightweight honeycomb core with adhesives. Honeycomb sandwich structures are commonly used in structures such as engine covers, wall panels, and soundproofing panels. To connect with other structural components, the honeycomb sandwich structure needs to be drilled.

[0004] Because the honeycomb core in a honeycomb sandwich structure has low strength and poor rigidity, it is prone to tearing during hole drilling. Therefore, current processing methods are mostly special machining or combined processes. Ultrasonic machining is the most commonly used special machining method. However, many manufacturers are limited by the lack of special equipment such as ultrasonic equipment and can only use conventional machining methods. The most common conventional machining method is the nesting drilling method, which involves first drilling a small hole and then using a nesting drill to enlarge the hole. This can effectively reduce the amount of cutting. However, during the hole drilling process, the honeycomb core is cut off in blocks, which cannot be broken up or removed in time, seriously affecting the quality of the hole. The process can only be repeated after drilling to a certain depth, retracting the tool, breaking up the chips, removing the chips, and then drilling again. Therefore, the processing efficiency is extremely low.

[0005] To break down the debris, existing technologies have explored various cutting tools for honeycomb sandwich structures, including tool holders with circumferentially arranged crushing blades and conical cutter discs. These tools use left-hand and right-hand rotations to perform staggered tooth cutting, thus breaking the debris into powder during the cutting process. However, because honeycomb sandwich structures are prone to collapse during cutting, the left-hand and right-hand rotations make the collapse problem even more likely. This results in the problem of the perimeter collapsing before the cutting process, leading to lower hole-making accuracy. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a cutting tool for processing metal honeycomb sandwich materials. The main cutting head rotates to cut the honeycomb. When a certain depth is reached, the removed honeycomb sandwich structure obstructs the revolution of the chip cutting head. At this point, the chip cutting head rotates by utilizing the mechanical transmission principle, thereby breaking up the removed honeycomb blocks without affecting the accuracy of the holes.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: A cutting tool for machining metal honeycomb sandwich materials, comprising: The substrate is capable of being connected to the power mechanism and has cavities. The tool holder is connected to the base through a transmission mechanism, allowing it to rotate relative to the base. The transmission mechanism is located in the cavity of the base, and a chip-breaking head is provided at the end of the tool holder away from the base. The main cutting head has one end detachably connected to the base body, and the other end is equipped with a sharp cutting edge that extends beyond the chipper head. The main cutting head slides through the honeycomb sandwich structure. The removed honeycomb sandwich structure obstructs the revolution of the chipper head. Under the action of the transmission mechanism, the tool holder drives the chipper head to rotate to chip the removed honeycomb sandwich structure.

[0008] As described above, in a cutting tool for processing metal honeycomb sandwich materials, the tool holder and the chip-breaking head are coaxially arranged, and the central axis of the chip-breaking head is eccentrically arranged relative to the central axis of the main cutting head.

[0009] As described above, a cutting tool for processing metal honeycomb sandwich materials includes a transmission mechanism comprising a gear and a gear ring disposed on the inner wall of the substrate. The gear meshes with the gear ring and is mounted circumferentially on the tool holder. The outer diameter of the gear is smaller than the inner diameter of the gear ring, and fasteners are fixed circumferentially on the tool holder to define the position of the gear.

[0010] As described above, in a cutting tool for processing metal honeycomb sandwich materials, the base supports a bearing, which is sleeved around the tool holder in the circumferential direction, and the tool holder is provided with a limiting part to position the bearing.

[0011] As described above, a cutting tool for processing metal honeycomb sandwich materials, wherein the main cutting head includes a tool body, the tool body is a truncated cylindrical structure, and the inclined surface of the tool body is an arc surface; One end of the blade is provided with the cutting edge to form the cutting edge end, and the other end of the blade is a flange end. The flange end of the blade is connected to the base body, and a section of the blade near the flange end is sealed to the blade shank.

[0012] As described above, in a cutting tool for processing metal honeycomb sandwich materials, the section of the tool body near the flange end is a connecting section, which is sealed to the tool shank. From the cutting edge of the tool body to the connecting section, the wall thickness of the tool body gradually increases, and the distance from the cutting edge of the tool body to the connecting section is greater than the length of the chip-breaking head.

[0013] As described above, in a cutting tool for processing metal honeycomb sandwich materials, the end of the substrate away from the main cutting head is connected to a tail rod, which is a T-shaped structure and is detachably connected to the substrate.

[0014] Secondly, the present invention also provides a cutting device for processing metal honeycomb sandwich materials, including a dust collection mechanism and a cutting tool for processing metal honeycomb sandwich materials, wherein the dust collection end of the dust collection mechanism is arranged facing the chip cutting head.

[0015] Thirdly, the present invention also provides a method for assembling a cutting tool for machining metal honeycomb sandwich materials, comprising the following: A transmission mechanism is installed at the tool holder; The tool holder passes through one end of the main cutting head, and the chip-breaking head is installed at the end of the tool holder away from the transmission mechanism; The transmission mechanism is placed inside the base body, connecting the base body to the main cutting head.

[0016] Fourthly, the present invention also provides a processing technology for metal honeycomb sandwich materials, employing the aforementioned cutting device for processing metal honeycomb sandwich materials, comprising the following: Install the base at the power mechanism; Align the cutting edge of the main cutting head with the hole in the outer layer of the honeycomb sandwich, start the power mechanism to drive a cutting tool for processing metal honeycomb sandwich materials to start rotating. Along the axial feed direction of the tool holder, the cutting edge of the main cutting head begins to cut the honeycomb sandwich structure. The removed honeycomb sandwich structure enters the middle part of the main cutting head, and the chip chipper begins to contact the removed honeycomb sandwich structure. The revolution of the chip chipper begins to be obstructed, and the revolution begins to break up part of the honeycomb sandwich structure. At the same time, due to the obstruction of revolution, the substrate begins to rotate under the drive of the transmission mechanism. The resulting rotational motion causes the chip chipper to start to break up chips. The dust extraction mechanism starts working to suck away the generated debris, keeping the holes free of clumps of honeycomb and honeycomb debris until the hole making is completed.

[0017] The beneficial effects of the present invention are as follows: 1) This invention provides a combined cutting tool, which includes a base, a tool holder, and a main cutting head. The tool holder is connected to the base through a transmission mechanism. One end of the main cutting head is provided with a cutting edge. Driven by a power mechanism, the main cutting head slides and cuts the honeycomb sandwich structure. The removed honeycomb sandwich structure obstructs the revolution of the chipping head. Under the action of the transmission mechanism, the tool holder drives the chipping head to rotate to chip the removed honeycomb sandwich structure. The cutting of the honeycomb sandwich structure is achieved by the cooperation of the main cutting head and the chipping head, forming a hole. The sliding cutting of the main cutting head avoids the problem of hole collapse in the honeycomb sandwich structure. The chipping is done by the chipping head, without the need for left-hand or right-hand rotation, ensuring cutting accuracy.

[0018] 2) The hole-making equipment provided by the present invention uses a dust collection mechanism in conjunction with a cutting tool for processing metal honeycomb sandwich materials. As the combined cutting tool for making holes in the honeycomb sandwich works, the dust collection mechanism processes the debris. In each hole making, there is no need to retract the tool and remove the debris multiple times. The cut-off block honeycomb sandwich structure can be broken into debris in time, which greatly reduces the workload of the operator and significantly improves the production efficiency.

[0026] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. As described in the background section, the existing technology has a problem that left-hand and right-hand staggered tooth cutting affects the hole-making accuracy of honeycomb sandwich structures. In order to solve the above technical problem, the present invention proposes a cutting tool for machining metal honeycomb sandwich materials.

[0028] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a cutting tool for machining metal honeycomb sandwich materials includes: The base 11 is connected to the power mechanism and has a cavity; The cutter bar 4 is connected to the base 11 through a transmission mechanism, which allows the cutter bar 4 to rotate relative to the base 11. The transmission mechanism is placed in the cavity of the base 11, and a chipping cutter head 1 is provided at the end of the cutter bar 4 away from the base 11. The main cutting head 6 has one end detachably connected to the base 11, and the other end of the main cutting head 6 is provided with a sharp cutting edge that extends beyond the chipping head 1. The main cutting head 6 slides and cuts the honeycomb sandwich structure. The cut honeycomb sandwich structure obstructs the revolution of the chipping head 1. Under the action of the transmission mechanism, the tool holder drives the chipping head 1 to rotate to chip the cut honeycomb sandwich structure.

[0029] The combined cutting tool provided in this embodiment uses the main cutting head 6 and the chipping head 1 to cut the honeycomb sandwich structure and form a hole. The main cutting head 6 slides to avoid the problem of hole collapse in the honeycomb sandwich structure, and the chipping head 1 chipps the material without the need for left-hand or right-hand rotation, thus ensuring cutting accuracy.

[0030] It should be noted that the tool holder 4 and the chipper head 1 are coaxially arranged, and the central axis of the chipper head 1 is eccentrically arranged relative to the central axis of the main cutting head 6. The reason for this arrangement is that the inner diameter of the main cutting head 6 is larger than the outer diameter of the chipper head 1, thus ensuring the working range of the chipper head 1 and achieving sufficient chipping of the honeycomb sandwich structure to be removed.

[0031] In this embodiment, the transmission mechanism includes a gear 12 and a gear ring disposed on the inner wall of the base 11. The gear 12 meshes with the gear ring and is mounted in the circumferential direction of the tool holder 4. The outer diameter of the gear 12 is smaller than the inner diameter of the gear ring. Fasteners such as nuts are fixed in the circumferential direction of the tool holder 4 to limit the position of the gear 12.

[0032] It is easy to understand that the base supports the bearing, which is sleeved circumferentially within the tool holder 4. The tool holder 4 is equipped with a limiting part to position the bearing. The bearing is engaged with the tool holder 4. Specifically, the bearing is a deep groove ball bearing 10, which is supported by the base 11. The main function of the deep groove ball bearing 10 is to allow for more flexible relative movement between the tool holder 4 and the base 11. The base 11 is the base part of this combined tool, and all major components are connected to it. The base 11 provides a cavity for gear transmission. (Refer to...) Figure 4 As shown, a gear ring is arranged circumferentially on the inner side of the base 11. The gear 12 is assembled with the tool holder 4. The gear 12 and the gear ring of the base 11 mesh to transmit power, which enables the tool holder 4 to rotate.

[0033] Specifically, the chipper head 1 is used to break up the cut honeycomb structure. The hex bolt 2 and the first washer 3 are used to fasten the chipper head 1 to the tool holder 4. The tool holder 4 is used to connect the main cutting head 6 and drive the main cutting head 6 to rotate. The tool holder 4 and the chipper head 1 are connected by the first flat key 5. The function of the first flat key 5 is to prevent relative movement between the tool holder 4 and the chipper head 1 and to transmit torque.

[0034] It should be noted that the main cutting head 6 includes a cutter body 21, which is a truncated cylindrical structure to ensure the sharpness of the cutting edge for effective sliding cutting of the honeycomb sandwich structure. This structure also facilitates the exposure of the chip-removing head 1 and promotes chip removal during operation, preventing chip accumulation within the hole. The bevel of the cutter body 21 can be an arc-shaped surface. A cutting edge is provided at one end of the cutter body 21, which is positioned circumferentially around the cutter shank 4. The cutting edge of the cutter body 21 extends beyond the chip-removing head 1. The inner diameter of the cutter body 21... The outer diameter of the main cutting head 6 is larger than that of the chip cutter head 1. The other end of the cutter body 21 is a flange end. The cutting edge of the cutter body 21 is used to cut the honeycomb sandwich structure. The flange end is used to connect with the base body 11. The flange end is equivalent to the bearing end cover and plays a role in preventing the deep groove ball bearing 10 from axially moving. The countersunk bolt 8 is used to connect and fasten the flange end of the main cutting head 6 and the base body 11. A first sealing gasket 9 is set at the countersunk bolt 8. The first sealing gasket 9 is placed between the main cutting head 6 and the base body 11 to prevent dust from entering the gear transmission cavity. In this embodiment, the tool bar 4 and the gear 12 are connected by a second flat key 13. The function of the second flat key 13 is to prevent relative movement between the tool bar 4 and the gear 12 and to transmit torque. A nut 15 is provided at the end of the tool bar 4, and a second washer 14 is placed in the circumferential direction of the tool bar 4. The second washer 14 and the nut 15 are used to lock the gear 12 onto the tool bar 4. The section of the cutter body 21 near the flange end is the connecting section 22, which is sealed to the cutter shank 4. From the cutting edge of the cutter body 21 to the connecting section 22, the wall thickness of the cutter body 21 gradually increases to ensure the sharpness of the cutting edge. The distance from the cutting edge of the cutter body 21 to the connecting section 22 is greater than the length of the chipping head 1, leaving space for the chipping process of the chipping head 1 to ensure sufficient chipping.

[0035] The end of the base 11 away from the main cutting head 6 is connected to the tail rod 18. The tail rod 18 is a T-shaped structural component and is detachably connected to the base 11. Specifically, the tail rod 18 is a T-shaped structural component. One end of the tail rod 18 is provided with a bolt hole for connection with the base 11. The second sealing gasket 16 is placed between the base 11 and the tail rod 18 to prevent dust from entering the gear transmission cavity. The flange part of the tail rod 18 contacts the end face of the base 11 and is connected by a countersunk head hex bolt 17. The countersunk head hex bolt 17 is used to connect and fasten the base 11 and the tail rod 18. refer to Figure 2 As shown, the base 11 is provided with multiple main cutting head positioning pins 19 at one end for connection with the main cutting head 6. The main cutting head positioning pins 19 are located on both sides of one of the countersunk bolts 8. The interval angle between the two main cutting head positioning pins 19 is less than 90°. There are 4 countersunk bolts 8 to ensure a reliable connection between the base and the main cutting head 6. Positioning pin holes are provided at corresponding positions on the main cutting head 6 and the base 11. The positioning pin holes cooperate with the main cutting head positioning pins 19. The setting of the main cutting head positioning pins 19 effectively prevents the main cutting head 6 and the base 11 from moving relative to each other and plays a positioning role. refer to Figure 3 As shown, a tail rod positioning pin 20 is provided at one end of the base 11 for connection with the tail rod 18. The tail rod 18 is provided with a positioning pin hole that matches the tail rod positioning pin 20. There are two tail rod positioning pins 20, which are set along the radial direction of the tail rod 18. The purpose of setting the tail rod positioning pin 20 is to prevent relative movement between the base 11 and the tail rod 18 and to play a positioning role.

[0036] The end of the cutter body 21 near the flange is sealed to the cutter shank 4. Specifically, a dustproof sealing ring 7 is provided between the cutter body 21 and the cutter shank 4 to prevent dust from entering the gear transmission cavity.

[0037] In summary, the combined cutting tool provided in this embodiment cuts the honeycomb sandwich structure by rotating the main cutting head 6. When the set depth is reached, the cut honeycomb sandwich structure obstructs the revolution of the chip cutting head. At this time, the mechanical transmission principle is used to realize the rotation of the chip cutting head 1 by the meshing of the gear and the gear ring, thereby cutting the cut honeycomb block into pieces. The overall structure is reasonably set, and the main cutting head makes room for the chips of the chip cutting head 1, avoiding chip blockage.

[0038] Example 2 This embodiment provides a cutting device for processing metal honeycomb sandwich materials, including a dust collection mechanism and a cutting tool for processing metal honeycomb sandwich materials as described in Embodiment 1. The dust collection end of the dust collection mechanism is set towards the chip removal tool head, which is just right to match the tool body of the oblique cylindrical structure. The tool body of the oblique cylindrical structure makes room to facilitate the removal of chips.

[0039] The vacuuming mechanism can be an existing vacuum cleaning mechanism.

[0040] Example 3 This embodiment provides a method for assembling cutting tools for machining metal honeycomb sandwich materials, including the following: During assembly, first press the deep groove ball bearing 10 onto the tool holder 4, install the second flat key 13 into the keyway of the tool holder 4, install the gear 12 onto the tool holder 4, put the second washer 14 around the tool holder 4, install the nut 15 and tighten it. Insert the tool holder 4 through the flange end of the main cutting head 6, which has been fitted with the dustproof seal ring 7. Insert the first flat key 5 into the keyway at the other end of the tool holder 4. Align the keyway on the chip cutting head 1 with the first flat key 5. Fit the chip cutting head 1 onto the tool holder 4. Tighten the hexagonal bolt 2, which has been fitted with the first washer 3, through the chip cutting head 1 to the end of the tool holder 4. The first sealing gasket 9 is fitted onto the flange end face of the main cutting head 6, with each assembly hole corresponding to the others; Align the locating pin hole on the base 11 with the locating pin hole at the flange end of the main cutting head 6, adjust the position of the gear 12, press the base 11 onto the outer ring of the deep groove ball bearing 10, tighten the countersunk bolt 8 (no need to tighten), press the main cutting head locating pin 19, and then tighten the countersunk bolt 8. Insert the hexagonal countersunk bolt 17 into the countersunk hole of the tail rod 18, and press the tail rod locating pin 20 into the locating pin hole of the tail rod 18; put the second sealing gasket 16 on the hexagonal countersunk bolt 17, align the four hexagonal countersunk bolts 17 with the four threaded holes of the base 11 respectively, screw on the four hexagonal countersunk bolts 17, no need to tighten, then press on the tail rod locating pin 20, and then tighten the hexagonal countersunk bolts 17.

[0041] Example 4 This embodiment discloses a processing technology for metal honeycomb sandwich materials, employing a cutting device for processing metal honeycomb sandwich materials as described in Embodiment 2, including the following: Mount the tail rod 18 of the fully assembled honeycomb sandwich hole-making combination tool onto the power source transmission mechanism (machine tool chuck, or pneumatic / electric tool chuck). Align the single-edged tip of the main cutting head 6 with the hole in the outer layer of the honeycomb sandwich (the hole in the outer layer of the sandwich, such as aramid or carbon fiber composite material, has been machined and serves as a guide hole). Start the power source, and the honeycomb sandwich hole-making combination tool begins to rotate and feeds along the axial direction of the honeycomb sandwich hole-making combination tool. The sharp single edge of the main cutting head 6 begins to cut the honeycomb. The removed honeycomb sandwich structure begins to enter the middle part of the main cutting head 6, and the chipping head 1 begins to contact the removed honeycomb sandwich structure. The revolution of the chipping head 1 is obstructed, and the revolution motion begins to break up part of the honeycomb. At the same time, due to the obstruction of revolution, the internal gear of the substrate 11 begins to drive the gear 12 to rotate, thereby causing the chipping head 1 to start to rotate. The resulting rotational motion causes the sharp micro-blades of the chipping head 1 to start to break up the chips. At the same time, the attached dust suction device begins to suck up the generated chips. Therefore, the hole is always kept free of clumps of honeycomb and honeycomb chips until the hole making is completed.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
