Description

Technical Field

[0001] This invention relates to the field of aerospace material processing technology, specifically to a high-efficiency ultrasonic six-axis machining center. Background Technology

[0002] Aerospace materials, especially carbon fiber reinforced composites, aramid honeycomb structures, and G10 insulation sheets, have become key basic materials for modern aerospace vehicle manufacturing due to their superior specific strength, corrosion resistance, and lightweight advantages. In the manufacturing process of aircraft fuselage skin, wing components, and internal structural parts, these materials often need to be cut into complex geometric shapes. Because aerospace materials are composed of high-strength fibers and resin matrices, their processing not only places extremely high demands on the six-axis linkage precision of machine tools but also faces severe challenges in dust control.

[0003] Traditional aerospace material processing machine tools are mostly modified from general metal cutting equipment, which presents significant technical bottlenecks. First, traditional machine tools lack a fully enclosed dustproof design specifically for the characteristics of composite materials. The processing chamber often suffers from insufficient negative pressure or turbulent airflow, resulting in a large amount of fine dust splashing and spreading into the workshop environment with the cutting fluid, making it difficult to achieve truly dust-free operation. Second, traditional cooling methods often use large amounts of cutting fluid spraying, which not only results in waste liquid containing high concentrations of harmful dust, making subsequent solid-liquid separation difficult and polluting the environment, but also causes residual moisture on the workpiece surface due to the excessively thick liquid film, requiring an additional drying process. Traditional cutting tools rely solely on mechanical cutting edges for physical cutting, which can easily produce a pulling effect when facing high-strength fibers, resulting in obvious burrs, delamination, and fiber pull-out at the cut edges, seriously affecting the smoothness and finish of the finished product surface.

[0004] While existing ultrasonic six-axis machining centers have introduced ultrasonic vibration-assisted cutting technology, effectively reducing cutting forces and improving cut quality, they still have shortcomings in terms of continuous, dust-free, and microscopic surface modification of aerospace materials. Existing dust control systems mostly focus on simple lateral suction or partial coverage, lacking a fully enclosed laminar flow air curtain protection mechanism. They cannot effectively use positive pressure air curtains to suppress the outward diffusion of dust while thoroughly collecting fine dust settling under the conveyor belt and in the gaps, leading to easy accumulation of liquid and dust at the bottom of the equipment, affecting the stability and cleanliness of continuous production. On the other hand, existing ultrasonic equipment usually only directly couples high-frequency vibration energy to the tool itself, failing to make full use of special liquid media as energy transfer carriers. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency ultrasonic six-axis machining center with advantages such as fully enclosed laminar flow air curtain dust prevention, solving the problem of environmental pollution caused by the difficulty in completely controlling fine dust in the processing of aerospace composite materials.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency ultrasonic six-axis machining center, comprising a support frame, a PU conveyor table fixed on the upper surface of the support frame, a crossbeam fixed on the upper surface of the PU conveyor table, a cutting area provided on the upper side of the crossbeam, a dustproof processing mechanism for fully enclosing the cutting area provided on the upper side of the PU conveyor table, and an auxiliary mechanism for improving the surface flatness of the workpiece provided on the upper side of the PU conveyor table and to the right of the dustproof processing mechanism; The dustproof processing mechanism includes a sealing frame fixed to the upper side of the PU conveyor platform. A wind box is fixed at the center of the upper surface of the sealing frame. A fan A is fixed to the front side of the wind box and on the upper surface of the sealing frame. Two symmetrical hollow plates are fixed to the inner top wall of the sealing frame. An air duct is formed in each of the two hollow plates from top to bottom. An air curtain gun A is fixed on the left and right sides of the two hollow plates near their bottom surfaces. The air curtain gun A is connected to the air duct through a pipe. Support rods are fixed on the left and right sides of the upper surface of the wind box. The top of the two support rods is fixed with the same horizontal pipe. The horizontal pipe is connected to the two hollow plates and fixed with vertical pipes. At the same time, the air inlet and air outlet of the fan A are connected to the wind box and the horizontal pipe through pipes.

[0007] Furthermore, the cutting area includes a support beam, a five-axis ultrasonic cutting head, and an electrical cabinet, wherein the electrical cabinet is located on the front side of the support frame and includes a power module, a servo control system, a motion control system, and an ultrasonic generator.

[0008] Furthermore, the dustproof processing mechanism also includes a dustproof net fixed between the inner walls of the four sides of the air box. A hanging pipe with one end penetrating through and extending into the sealing frame is fixedly connected to both sides of the lower surface of the air box. The other end of the hanging pipe is connected to a side suction pipe, and multiple suction heads are connected to the outer sides of the two side suction pipes.

[0009] Furthermore, the dustproof processing mechanism also includes electric push rods fixed on the left and right sides of the upper surface of the sealing frame. One end of the output shaft of each of the two electric push rods passes through and extends into the sealing frame and is fixed with a connecting rod. The bottom end of the connecting rod is rotatably connected to a rubber wheel via a rotating shaft.

[0010] Furthermore, workpiece monitoring heads are fixed on both the left and right sides of the sealing frame, and workpiece inlets and workpiece outlets are respectively opened on the left and right sides of the sealing frame and below the workpiece monitoring heads.

[0011] Furthermore, the auxiliary mechanism includes a liquid tank fixed to the support beam, a water pump fixed to the front of the liquid tank, and the interior of the liquid tank filled with deionized water, surfactants, and corrosion inhibitors. Multiple mounting rods arranged in a ring array are also fixed to the support beam. The bottom ends of the multiple mounting rods are fixed to the same annular tube that encloses the ultrasonic cutting five-axis head. Multiple atomizing nozzles are fixedly connected to the lower surface of the annular tube. The water inlet of the water pump is connected to the liquid tank via a pipe, and the water outlet of the water pump is fixedly connected to an outlet pipe, with the other end of the outlet pipe connected to the annular tube.

[0012] Furthermore, the auxiliary mechanism also includes a side frame fixed on the PU conveying platform and located on the right side of the sealing frame. A hollow rod is rotatably connected inside the side frame via a bearing. A hot air box is fixed on the upper surface of the side frame, and a motor is fixed on the upper surface of the side frame. The motor and the hollow rod are connected by a belt drive.

[0013] Furthermore, the hot air box is a rectangular prism with a hollow interior and a missing right side. Inside the hot air box, a filter screen and a heating wire are fixed from right to left. A fan B is fixed on the upper surface of the hot air box. The air inlet and air outlet of the fan B are respectively connected to an air inlet pipe and an air outlet pipe, and the other end of the air inlet pipe is connected and fixed to the left side of the hot air box.

[0014] Furthermore, the auxiliary mechanism also includes air curtain guns B fixed to the inner walls of the left and right sides of the side frame, support rods fixed to the left and right sides of the upper surface of the hot air box, and the same connecting pipe A fixed to the top of the two support rods. The connecting pipe A is connected to the two air curtain guns B respectively by connecting pipe B. The air outlet pipe of the fan B is connected to the connecting pipe A and the hollow rod respectively, and the connection with the hollow rod is rotatably connected by a sealed bearing.

[0015] Furthermore, multiple equidistantly distributed hot air heads are fixed to the outer side of the hollow rod. The hot air output from the hot air box is driven by the fan B and then transported to the air curtain gun B through the connecting pipe A and the connecting pipe B to form a laminar air curtain covering the upper surface of the PU conveyor table and the workpiece outlet.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This high-efficiency ultrasonic six-axis machining center, through the synergistic effect of the dustproof processing mechanism, utilizes fan A to drive airflow through the hollow plate, air duct, and air curtain gun A to form a positive pressure laminar flow air curtain surrounding the cutting area, effectively blocking the outward diffusion of fine dust. At the same time, in conjunction with the hanging pipe, side suction pipe, and suction head, it performs strong negative pressure suction of the settled dust inside the sealing frame and under the PU conveyor table, achieving dual control of dust source suppression and end collection. In addition, the rubber wheel driven by the electric push rod can dynamically seal the gap between the sealing frame and the workpiece, further eliminating the risk of leakage and ensuring that the workshop environment reaches a true dust-free standard, avoiding the dust flying problem caused by airflow turbulence in traditional equipment.

[0017] 2. This high-efficiency ultrasonic six-axis machining center utilizes a water pump to precisely spray a mixture of deionized water, surfactant, and corrosion inhibitor onto the cutting area through atomizing nozzles. The cavitation effect of the liquid medium assists ultrasonic vibration, further reducing cutting force and smoothing burrs and fiber delamination at the microscopic level, achieving a mirror-like smoothness improvement. Subsequently, a motor drives a hollow rod to rotate, which, combined with heating from the heating wire in the hot air chamber and hot air generated by fan B, forms a hot air curtain covering the workpiece outlet through connecting pipe B and the hot air outlet. This instantly evaporates residual liquid film and prevents secondary oxidation. This process eliminates the need for traditional large-volume cutting fluid spraying and complex subsequent solid-liquid separation treatment, protecting the environment while ensuring high efficiency with immediate workpiece drying.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 This embodiment of a high-efficiency ultrasonic six-axis machining center includes a support frame 1, a PU conveyor table 2 fixed on the upper surface of the support frame 1, a crossbeam 3 fixed on the upper surface of the PU conveyor table 2, a cutting area 4 on the upper side of the crossbeam 3, a dustproof processing mechanism 5 for fully enclosed processing of the cutting area 4 on the upper side of the PU conveyor table 2, and an auxiliary mechanism 6 for improving the surface flatness of the processed parts on the upper side of the PU conveyor table 2 and to the right of the dustproof processing mechanism 5. The dustproof processing mechanism 5 includes a sealing frame 501 fixed to the upper side of the PU conveyor table 2. A wind box 502 is fixed at the center of the upper surface of the sealing frame 501. A fan A503 is fixed to the front side of the wind box 502 and located on the upper surface of the sealing frame 501. Two symmetrical hollow plates 504 are fixed to the inner top wall of the sealing frame 501. An air duct 505 is formed in each of the two hollow plates 504 from top to bottom. The left and right sides of the two hollow plates 504 are close to their bottom surfaces. Air curtain guns A506 are fixed at each location. Air curtain guns A506 are connected to air ducts 505 via pipes. Support rods 507 are fixed on both sides of the upper surface of air box 502. The top of the two support rods 507 is fixed with the same horizontal pipe 508. The horizontal pipe 508 is connected to the two hollow plates 504 and fixed with vertical pipes 509. At the same time, the air inlet and outlet of fan A503 are connected to the air box 502 and the horizontal pipe 508 via pipes.

[0022] It should be noted that by constructing a dustproof processing mechanism 5 consisting of a sealing frame 501, an air box 502, a fan A503, a hollow plate 504, and an air curtain gun A506, and utilizing the interconnected structure of the support rod 507, the horizontal pipe 508, and the vertical pipe 509 to form an efficient airflow circulation, a fully enclosed positive pressure laminar flow air curtain protection is achieved in the cutting area 4. This effectively confines dust within the enclosed space and prevents it from spreading outward, fundamentally solving the environmental pollution problem caused by the disorderly flying of dust in traditional open processing.

[0023] The cutting area 4 includes a support beam, an ultrasonic five-axis cutting head, and an electrical cabinet. The electrical cabinet is located on the front side of the support frame 1 and includes a power module, a servo control system, a motion control system, and an ultrasonic generator.

[0024] It should be noted that cutting zone 4 includes an ultrasonic cutting five-axis head and an integrated electrical cabinet containing a power module, servo control system, motion control system and ultrasonic generator. Through the combination of high-precision six-axis linkage and ultrasonic high-frequency vibration technology, the cutting force during the cutting of high-strength aerospace composite materials is significantly reduced, effectively avoiding material delamination and fiber pull-out, thereby greatly improving the processing accuracy and cut quality of complex geometric workpieces.

[0025] The dustproof processing mechanism 5 also includes a dustproof net 510 fixed between the four inner walls of the air box 502. The left and right sides of the lower surface of the air box 502 are each fixedly connected to a hanging pipe 511 that extends through and into the sealing frame 501. The other end of the hanging pipe 511 is connected to a side suction pipe 512. Multiple suction heads 513 are connected to the outside of the two side suction pipes 512.

[0026] It should be noted that a dustproof net 510, a hanging pipe 511, a side suction pipe 512, and multiple suction heads 513 have been added to the dustproof processing mechanism 5, forming a dual dust removal system of "top positive pressure blocking + bottom negative pressure suction". This system can powerfully collect the fine dust that settles inside the sealing frame 501 and in the gaps of the PU conveyor table 2, completely eliminating the hidden dangers of dust and liquid accumulation at the bottom of the equipment, and ensuring the cleanliness and stability of the equipment operation during continuous production.

[0027] The dustproof processing mechanism 5 also includes electric push rods 514 fixed on the left and right sides of the upper surface of the sealing frame 501. One end of the output shaft of each of the two electric push rods 514 passes through and extends into the sealing frame 501 and is fixed with a connecting rod 515. The bottom end of the connecting rod 515 is rotatably connected to a rubber wheel 516 via a rotating shaft.

[0028] It should be noted that the dynamic sealing assembly consisting of electric push rod 514, connecting rod 515 and rubber wheel 516 can automatically adjust the vertical floating height of rubber wheel 516 according to the size or position deviation of the workpiece, closely fit the surface of the workpiece or the edge of the conveyor table, and effectively seal the tiny leakage gaps between the sealing frame 501 and the workpiece. This enhances the tightness of the fully enclosed processing environment and eliminates the risk of dust leakage.

[0029] The sealing frame 501 has workpiece monitoring heads fixed on both the left and right sides, and workpiece inlet and workpiece outlet are respectively opened on the left and right sides of the sealing frame 501 and below the workpiece monitoring heads.

[0030] It should be noted that by setting workpiece monitoring heads on both sides of the sealing frame 501 and planning clearly defined workpiece inlets and outlets, intelligent sensing and automated process control of the workpiece entry and exit status are realized. This not only optimizes the processing cycle but also ensures the stable transmission of workpieces in a fully enclosed environment through precise positioning monitoring, thereby improving the overall automation level and operational safety of the equipment.

[0031] The auxiliary mechanism 6 includes a liquid tank 601 fixed to a support beam. A water pump 602 is fixed to the front of the liquid tank 601. The interior of the liquid tank 601 is filled with deionized water, surfactants, and corrosion inhibitors. Multiple mounting rods arranged in a ring array are also fixed on the support beam. The bottom ends of the multiple mounting rods are fixed to the same annular tube 603 that wraps around the ultrasonic cutting five-axis head. Multiple atomizing nozzles 604 are fixedly connected to the lower surface of the annular tube 603. The water inlet end of the water pump 602 is connected to the liquid tank 601 through a pipe. The water outlet end of the water pump 602 is fixedly connected to an outlet pipe 605, and the other end of the outlet pipe 605 is connected to the annular tube 603.

[0032] It should be noted that the liquid-phase auxiliary system, which includes deionized water, surfactants, and corrosion inhibitors, precisely sprays the mixture onto the cutting point through a water pump 602, annular pipe 603, and atomizing nozzle 604. The cavitation effect of the liquid medium assists ultrasonic vibration, smoothing out burrs and delamination at the microscopic level, significantly improving the smoothness and finish of the workpiece surface, while reducing waste liquid generation, demonstrating the advantages of green processing.

[0033] The auxiliary mechanism 6 also includes a side frame 606 fixed on the PU conveying table 2 and located on the right side of the sealing frame 501. A hollow rod 607 is rotatably connected inside the side frame 606 via a bearing. A hot air box 608 is fixed on the upper surface of the side frame 606. A motor 609 is fixed on the upper surface of the side frame 606. The motor 609 and the hollow rod 607 are connected by a belt drive.

[0034] It should be noted that the structural design of driving the hollow rod 607 to rotate by the motor 609 provides a power basis for the subsequent hot air conveying. Combined with the layout of the side frame 606 and the hot air box 608, an independent heating and drying module is constructed, which can treat the workpiece immediately after processing. This effectively solves the problems of secondary oxidation, deformation and the need for additional drying processes caused by residual cutting fluid in traditional processes.

[0035] The hot air box 608 is a hollow cuboid with a missing right side. Inside the hot air box 608, from right to left, a filter screen and an electric heating wire are fixed. A fan B610 is fixed on the upper surface of the hot air box 608. The air inlet and air outlet of the fan B610 are connected to an air inlet pipe and an air outlet pipe, respectively. The other end of the air inlet pipe is connected and fixed to the left side of the hot air box 608.

[0036] It should be noted that the internal structure of the hot air box 608 has been optimized, with filters and heating wires installed sequentially to ensure that the hot air supplied to the system is purified and the temperature is controllable. Combined with the efficient drive of the fan B610, it can provide a stable and clean high-temperature airflow source, providing reliable thermal energy for subsequent laminar flow air curtain drying and avoiding impurities from contaminating the workpiece surface.

[0037] The auxiliary mechanism 6 also includes air curtain guns B611 fixed to the inner walls of the left and right sides of the side frame 606, support rods 612 fixed to the left and right sides of the upper surface of the hot air box 608, the top of the two support rods 612 fixed with the same connecting pipe A613, and connecting pipes B614 fixed to the two air curtain guns B611 respectively. The air outlet pipe of the fan B610 is connected to the connecting pipe A613 and the hollow rod 607 respectively, and the connection with the hollow rod 607 is rotatably connected by a sealed bearing.

[0038] It should be noted that, through the interconnected design of support rod 612, connecting pipe A613, connecting pipe B614 and air curtain gun B611, the hot air output by fan B610 is efficiently transported to the workpiece outlet area, forming a laminar hot air curtain covering the upper surface of PU conveyor table 2 and the outlet, realizing multi-directional uniform distribution of hot air, greatly improving drying efficiency and ensuring no dust residue at the workpiece outlet.

[0039] The hollow rod 607 has multiple equidistantly distributed hot air heads fixed on its outer side. The hot air output from the hot air box 608 is driven by the fan B610 and then transported to the air curtain gun B611 through the connecting pipe A613 and the connecting pipe B614 to form a laminar air curtain covering the upper surface of the PU conveyor table 2 and the workpiece outlet.

[0040] It should be noted that the hot air output method has been refined. The hot air heads distributed at equal intervals on the outer side of the hollow rod 607 work together with the air curtain gun B611 to form an all-round, high-density laminar hot air curtain. This not only accelerates the instantaneous evaporation of the residual liquid film on the workpiece surface, but also prevents external dust from re-attaching through the laminar flow barrier, truly achieving a high-quality processing effect of "cutting and drying immediately, dust-free and stain-free".

[0041] The core motion guiding components used in this application are all mature industrial standard parts, falling within the scope of existing technology, specifically including: Guide rail slider: Used for motion guidance along the X, Y, and Z axes. This is a mature linear motion component widely used in the machine tool industry, possessing high rigidity and high precision characteristics.

[0042] Lead screw: As a transmission element, it converts rotary motion into linear motion. TBI lead screws are a common standard component in the field of precision mechanical transmission, and the technology is very mature.

[0043] Rack and pinion: Used for large stroke movements such as beam drives. This type of transmission is extremely common in large CNC equipment.

[0044] Bearings: support rotating parts.

[0045] Conclusion: The aforementioned guide shafts, lead screws, guide rails, and bearings are all standard industrial components that are known and commonly used. Their selection, fitting, and application principles are already routine technical means in the fields of mechanical design and CNC, and there is no need to provide additional explanations of their underlying principles in this application.

[0046] The six-axis linkage X, Y, Z, C, B, U functions of this equipment are based on the mature RTCP tool tip tracking control technology, and are also an integration of existing technologies. Technical architecture: Based on the X and Y plane rectangular coordinate system, the machine head is driven by the Y-axis moving crossbeam. The machine head integrates the linkage of Z-axis up and down movement, C-axis rotation of the tool holder, B-axis rotation through the Z-axis center, and U-axis amplitude rod / tool ​​swing.

[0047] Implementation method: Utilizing the DMD six-axis linkage ultrasonic dedicated control system with RTCP function, combined with Yaskawa servo motors and absolute encoders, integrated control of material beveling and three-dimensional cutting is achieved.

[0048] Industry position: Five-axis / six-axis linkage machining technology has been widely used in aerospace and composite material cutting fields. The core innovation of this application lies in combining ultrasonic high-frequency vibration cutting technology with the existing six-axis linkage structure to solve the problems of blade sticking and delamination in difficult-to-process materials such as aramid honeycomb, rather than making a disruptive invention to the mechanical structure or control algorithm of the six-axis linkage itself.

[0049] In summary, the guide shaft system and six-axis linkage architecture in this application are both built on mature existing technologies. The focus is on the optimization of processing technology for specific materials such as aerospace composite materials and the innovative design of auxiliary systems such as dust prevention and drying.

[0050] The working principle of the above embodiments is as follows: When the aerospace composite material workpiece to be processed is placed on the PU conveyor table 2, the conveyor table moves the workpiece toward the cutting area 4. At this time, the dustproof processing mechanism 5 located on the support frame 1 begins to work in coordination.

[0051] When the blower A503 starts, it draws in and pressurizes air from the air box 502. The airflow enters the horizontal pipe 508 through the pipe, and then is diverted through the vertical pipe 509 to the air duct 505 inside the hollow plates 504 on both sides. The high-pressure airflow is finally ejected at high speed through the air curtain gun A506, forming a positive pressure laminar flow air curtain surrounding the cutting area 4 inside the sealing frame 501. This air curtain effectively blocks the outward diffusion of fine dust generated by cutting. At the same time, the negative pressure effect generated by the blower A503 is transmitted through the air box 502. With the filtering effect of the dustproof net 510, the airflow in the hanging pipe 511 is drawn out. The side suction pipe 512 and its multiple suction heads 513 at the end penetrate deep into the interior of the sealing frame 501 and the gap below the PU conveying table 2, powerfully sucking up the settled fine dust and splashing particles, realizing closed-loop control of source suppression and end collection.

[0052] If there are slight deviations in the size or position of the workpiece, the electric push rod 514 drives the connecting rod 515 and the bottom rubber wheel 516 to float up and down, closely adhering to the surface of the workpiece or the edge of the conveyor table, thereby eliminating leakage gaps between the sealing frame 501 and the workpiece and ensuring the airtightness of the dustproof system.

[0053] When the workpiece enters the cutting zone 4 for processing, the ultrasonic cutting five-axis head starts high-frequency vibration. At the same time, the liquid tank 601 in the auxiliary mechanism 6 is filled with a mixture of deionized water, surfactant and corrosion inhibitor. The mixture is pressurized by the water pump 602 and transported to the annular pipe 603 through the liquid outlet pipe 605. Finally, it is evenly sprayed onto the contact point between the tool and the workpiece by the atomizing nozzle 604. The atomized liquid medium generates a strong cavitation effect under the high-frequency vibration of the ultrasonic waves. This not only helps the tool cut high-strength fibers and reduces the cutting force, but also smooths out the burrs and delamination at the microscopic level, significantly improving the flatness and smoothness of the processed surface.

[0054] Auxiliary mechanism 6 synchronously starts the drying module: motor 609 drives hollow rod 607 to rotate, fan B610 starts, drawing outside air into hot air box 608. After the air is purified by internal filter and heated by electric heating wire, it forms high-temperature clean hot air. The hot air enters hot air box 608 through air inlet pipe, and is then delivered by fan B610 through air outlet pipe to connecting pipe A613 and connecting pipe B614. Finally, it is sprayed out from air curtain gun B611 and hot air head on the outside of hollow rod 607. This hot air forms a layer of covering laminar flow hot air curtain on the right side of side frame 606 and workpiece outlet. This hot air curtain quickly evaporates the trace liquid film remaining on the surface of the workpiece, preventing moisture from penetrating into the material and causing deformation or oxidation. Subsequently, the processed workpiece slides out from the workpiece outlet. The entire processing is completed in a dust-free, waste liquid-free environment with a high surface finish.
