Description

Technical Field

[0001] This invention relates to the field of ultrasonic rolling technology, and in particular to an ultrasonic-enhanced laser additive ultrasonic rolling robot for lightweight metals. Background Technology

[0002] The automotive transmission system is the core unit that ensures the efficiency of vehicle power transmission and driving stability. Aluminum alloy transmission rings are widely used in key components such as gearboxes and differentials due to their advantages such as lightweight, high specific strength, and good thermal conductivity. These rings need to meet two core requirements: First, the surface must have a high-precision limiting structure (such as a limiting ring) to achieve precise matching with adjacent components and avoid axial movement during transmission. Second, the surface layer must have excellent density, wear resistance, and fatigue resistance to withstand alternating loads, frictional impacts, and vibration stresses under transmission conditions. As the automotive industry upgrades towards lightweight and high-performance, higher requirements are placed on the manufacturing precision and service reliability of aluminum alloy transmission rings. The limiting structure must be firmly integrated with the ring body to avoid problems such as stress concentration and insufficient bonding strength caused by traditional mechanical connections. Currently, the mainstream method for preparing locating ring blanks is sand casting or die casting. Due to the uneven cooling rate of the molten aluminum alloy in the mold, a porous area with pores is easily formed at the root of the locating ring, accompanied by coarse columnar crystal structure. This area becomes a stress concentration source, directly weakening the structural load-bearing capacity. Although subsequent milling and grinding processes can improve the surface precision, they cannot eliminate the internal porosity and grain boundary defects. During machining, microcracks are easily induced on the surface of the locating ring, resulting in a significant decrease in its fatigue resistance. This makes it difficult to meet the long-term use requirements of alternating loads and high-frequency vibrations under automotive transmission conditions. Summary of the Invention

[0027] Working principle: The ultrasonic rolling mechanism 2 consists of a housing, an ultrasonic generator, a piezoelectric transducer, an amplitude transformer, and a cemented carbide rolling head. The ultrasonic generator, piezoelectric transducer, amplitude transformer, and cemented carbide rolling head are all installed inside the housing. The piezoelectric transducer is installed at the bottom of the ultrasonic generator, and the amplitude transformer is installed at the bottom of the piezoelectric transducer. The bottom end of the amplitude transformer is fixedly connected to the cemented carbide rolling head, and the cemented carbide rolling head penetrates through the bottom of the housing. The bottom end of the cemented carbide rolling head is spherical, which facilitates its action on the molten metal. Laser generator 3 consists of a pump source, gain medium, resonant cavity, optical focusing system, cooling system, and control system. The pump source is the energy source for laser generation, commonly a semiconductor laser array or flash lamp. The gain medium is the core component for laser amplification; in light metal additive manufacturing, it is often a water-cooled Nd:YAG crystal doped Nd:YAG or fiber-core fiber laser. The resonant cavity consists of a total reflection mirror and a partial reflection mirror, with parallel ends and coaxial with the gain medium. The optical focusing system includes a collimating mirror, a focusing mirror (often made of ZnSe), and optical path adjustment components, mounted at the front of the module. The cooling system consists of water-cooled pipes or air-cooled fans, attached to the gain medium and pump source for heat dissipation. The control system includes a drive circuit, a power regulator, and a timing controller, connected to the robot's main control system. When using laser generator 3, after the pump source starts, it converts electrical energy into optical energy (semiconductor laser or thermal flash lamp), irradiating the gain medium. After absorbing energy, the internal atoms of the gain medium are excited to a higher energy level, forming a "…". In a population inversion state where "the number of high-energy atoms > the number of low-energy atoms", high-energy atoms spontaneously transition and release photons. These photons reflect back and forth in the resonant cavity, constantly colliding with other high-energy atoms, triggering stimulated emission and generating a large number of photons of the same frequency and phase, thus achieving optical amplification. Some mirrors allow a small amount of amplified laser light to pass through, which is then collimated and focused by an optical focusing system to form a very small spot with a diameter of 0.1–1 mm, outputting a high-energy laser beam. The control system adjusts parameters such as laser power (100–5000 W) and pulse frequency in real time according to the robot's processing path instructions to ensure precise melting of the light metal powder. In this design, light metal powder is placed between a ceramic retaining ring 49 and a circular ring, and a high-energy laser is emitted by a laser generator 3 to rapidly melt it. The molten material is then compacted by the hard alloy rolling head of the ultrasonic rolling mechanism 2. The ultrasonic rolling mechanism 2 and the laser generator 3 are relatively common to those skilled in the art and will not be described in detail here. When the lightweight metal ultrasonic rolling robot is in use, the circular ring is fitted onto the surface of the guide member 411. The top of the guide member 411 is pointed, and the diameter of the bottom of the guide member 411 matches the inner diameter of the circular ring. This guides the circular ring to fit against the inner wall of the ceramic retaining ring 49. The inner wall of the ceramic retaining ring 49 is coated with an aluminum nitride (AlN) ceramic coating, which is suitable for aluminum alloy applications. It has good thermal conductivity, which can accelerate the cooling of molten metal. The coating thickness is controlled at 20-30 μm, and the surface roughness Ra≤0.4 μm reduces the friction and adhesion between the powder and the coating, ensuring uniform powder distribution. Furthermore, the ceramic retaining ring 49 is made of ceramic material, which has extremely poor chemical compatibility with solid aluminum alloys. It will not undergo metallurgical bonding with aluminum alloys at high temperatures, and liquid aluminum alloys cannot wet the ceramic surface. During the process of metal powder melting and solidification, the ceramic baffle only serves as a physical limit. The solidified metal has no adhesion to the baffle surface and can be easily separated without sticking. This allows the metal powder to be poured into the storage box 71 and the motor 413 to be started. The operation of the motor 413 can drive the threaded rod 414 to rotate. As the threaded rod 414 rotates, the square plate 412 can slide downward under the action of the thread. When the square plate 412 moves downward to the limit position, the motor 413 drives the threaded rod 414 to rotate in the opposite direction. The reverse rotation of the threaded rod 414 can drive the square plate 412 to slide upward until the square plate 412 moves to the initial height. During this process, the square plate 412 moves longitudinally back and forth. As the square plate 412 moves downward, its movement causes the ball 416 to slide on the surface of the longitudinal sliding groove 43. Under the constraint of the longitudinal sliding groove 43, the outer bushing 42 does not rotate. When the square plate 412 moves downward, it contacts the inclined surface 79 on the upper surface of the trapezoidal plate 78. As the square plate 412 moves, the inclined surface 79 causes the trapezoidal plate 78 to move towards the auxiliary sliding plate 77. The movement of the trapezoidal plate 78 drives the auxiliary sliding plate 77 to move synchronously via the positioning rod 710. The movement of plate 77 drives the movement of optical axis 726 via U-shaped side plate 711. This allows U-shaped plate 712 to rotate on the surface of optical axis 713, thereby driving the storage box 71 towards the ceramic retaining ring 49. When U-shaped plate 712 rotates, it stretches tension spring 714, allowing the storage box 71 to return to its original position after the applied force is removed, relying on the elastic potential energy of tension spring 714. The movement of the storage box 71 drives T-shaped plate 74 to slide inside T-shaped groove 75 via support plate 73, thus... To ensure the smooth sliding of the storage box 71, and after the trapezoidal plate 78, on the side away from the positioning rod 710, is in contact with the side of the square plate 412, the umbrella roller 724 and the annular cut surface 718 on the surface of the turntable 47 are in contact. As the auxiliary slide plate 77 moves, it can compress the second spring 723, so that there is a suitable force between the umbrella roller 724 and the turntable 47. When the square plate 412 and the trapezoidal plate 78, on the side away from the positioning rod 710, are in contact, the compressive force on the second spring 723 can be stabilized. At this time, the cylinder 72 is located at... One end of the storage box 71 is located above the space formed by the ceramic retaining ring 49 and the ring. When the square plate 412 and the trapezoidal plate 78 are attached on the side away from the positioning rod 710, the ball 416 inside the square plate 412 moves into the interior of the spiral groove 44. As the square plate 412 continues to move downward, the ball 416 can slide inside the spiral groove 44, thereby driving the outer bushing 42 to rotate. The rotation of the outer bushing 42 drives the top turntable 47, guide 411, ceramic retaining ring 49 and ring to rotate synchronously. After the umbrella wheel 724 and the turntable 47 are in contact, the rotation of the turntable 47 can drive the umbrella wheel 724 to rotate. The rotation of the umbrella wheel 724 drives the positioning shaft 725 to rotate. The rotation of the positioning shaft 725 drives the synchronous wheel 719 to rotate. Under the action of the two synchronous wheels 719 through the synchronous belt 720, the spiral rod 716 can be driven to rotate inside the cylinder 72. As the spiral rod 716 rotates, the metal powder inside the storage box 71 can be transported inside the cylinder 72 and flow out from the end of the cylinder 72. At this time, the metal powder falls above the space formed by the ceramic baffle ring 49 and the ring. As the ceramic baffle ring 49 and the ring rotate, the metal powder can be evenly spread inside the space formed by the ceramic baffle ring 49 and the ring. The square plate 412 moves down at a constant speed, which can make the turntable 47 rotate at a constant speed, which in turn makes the spiral rod 716 rotate at a constant speed, and thus the metal powder is transported at a constant speed to the space formed by the ceramic baffle ring 49 and the ring. As the square plate 412 moves down, when the side of the square plate 412 slides out from the side of the trapezoidal plate 78, the force applied to the U-shaped plate 712 is removed. At this time, the elastic potential energy of the tension spring 714 pulls the storage box 71 back to its original position through the U-shaped plate 712. At this time, the umbrella wheel 724 is no longer in contact with the turntable 47, which causes the spiral rod 716 to stop rotating, thereby stopping the conveying of metal powder. Since the spiral groove 44 has two turns, when the square plate 412 slides off the surface of the trapezoidal plate 78, the turntable 47 rotates exactly one turn. At this time, the laser generator 3 is activated. The laser emitting end of the laser generator 3 is aimed at the metal powder inside the ceramic retaining ring 49. The laser generator 3 emits a high-energy laser to quickly melt the metal powder at the corresponding position. At this time, the square plate 412 drives the ball 416 to continue sliding downward, which in turn allows the outer bushing 42 to continue rotating. After the outer bushing 42 drives the turntable 47 to rotate one turn, the ball 416 moves to the position of the longitudinal groove 45. The metal powder inside the ceramic retaining ring 49 is completely melted after one rotation. When the ball 416 just moves to the position of the second longitudinal sliding groove 45, the bottom surface of the bottom connecting block 53 is in contact with the crossbar 52. As the bottom connecting block 53 moves downward, it drives the crossbar 52 to move downward synchronously. The movement of the crossbar 52 causes the two sliding shafts 55 to slide inside the inclined groove 56. At this time, the crossbar 52 moves diagonally downward and can slide inside the vertical rod 510. The movement of the crossbar 52 causes the vertical rod 510 to slide inside the U-shaped sleeve 57. As the vertical rod 510 drives the rotating shaft 522 to move downward, it can apply a downward force to the second U-shaped plate 521, thereby causing the L-shaped rod to move downward. 519 rotates inside the L-shaped rod 520, and rotates synchronously with the ultrasonic rolling mechanism 2 driven by the L-shaped rod 519. When the U-shaped plate 521 and the first support rod 523 are in contact, the U-shaped plate 521 continues to move downward as the vertical rod 510 continues to move downward. At this time, the movement of the U-shaped plate 521 drives the L-shaped rod 520 to move synchronously. The movement of the L-shaped rod 520 drives the hollow rod 516 and the top plate 518 to move synchronously. When the top plate 518 moves downward, it applies a force to the rotating shaft 517, which causes the Z-shaped rod 512 to rotate on the surface of the rotating shaft 511. Z-shaped rod 512 rotates against the gravity of counterweight 514. During the downward movement of hollow rod 516, under the action of two parallel diagonal braces 515, hollow rod 516 can tilt downwards. During this movement, hollow rod 516 and U-shaped plate 59 remain parallel. As the ultrasonic rolling mechanism 2 moves, until one end of crossbar 52 is in contact with the side of bottom connecting block 53, the position of ultrasonic rolling mechanism 2 is restricted by the gravity of counterweight 514. During this process, ultrasonic rolling mechanism 2 rotates from a vertical position at a certain angle and tilts towards the ceramic after reaching a suitable angle. When the inner movement of the retaining ring 49 occurs, and the side of the crossbar 52 is in contact with the bottom connecting block 53, the hard alloy rolling head of the ultrasonic rolling mechanism 2 contacts the molten material inside the ceramic retaining ring 49 and applies appropriate pressure to the molten material. After the hard alloy rolling head of the ultrasonic rolling mechanism 2 contacts the molten material inside the ceramic retaining ring 49, the square plate 412 drives the ball 416 to move downward, causing the ball 416 to slide into the interior of the spiral groove 46. Guided by the spiral groove 46, when the ball 416 slides to the bottom position of the spiral groove 46, the turntable 47 rotates exactly one revolution. When the ball 416 just slides into the spiral groove 46, the ultrasonic rolling mechanism 2 is activated. The hard alloy rolling head of the ultrasonic rolling mechanism 2 compacts the molten material. When the turntable 47 drives the ceramic retaining ring 49 to rotate once, the molten material compaction process at the corresponding position is completed. When the bottom connecting block 53 is about to move to the bottommost position, the bottom connecting block 53 contacts the inclined support plate 63 and applies a force to the inclined support plate 63, causing the inclined support plate 63 to push the L-shaped rod 62 to slide inside the L-shaped groove 66. As the L-shaped rod 62 moves, it compresses the spring 64. Under the action of the inclined support plate 63 being tilted, the top of the inclined support plate 63 can be easily inserted into the triangular groove 65. At this time, the bottom connecting block 53 moves to the bottommost position. When the square plate 412 moves upward, under the action of the vertical corner of the inclined support plate 63 combined with the elastic potential energy of the spring 64, the position of the L-shaped rod 62 can be restricted. When the diagonal brace 63 pushes the L-shaped rod 62 to move, the movement of the L-shaped rod 62 drives the horizontal plate 58 to move laterally through the connecting plate 61. The movement of the horizontal plate 58 drives the vertical rod 510 and the U-shaped plate 59 to move synchronously, thereby driving the hard alloy rolling head of the ultrasonic rolling mechanism 2 to move laterally a suitable distance towards the ring. When the position of the L-shaped rod 62 is restricted, the position of the ultrasonic rolling mechanism 2 after movement can also be restricted. At this time, the square plate 412 drives the bottom connecting block 53 to move upward synchronously. When the side of the bottom connecting block 53 and the crossbar 52 come into contact, the square plate 412 moves downward to the bottommost end and when the square plate 412 drives the bottom connecting block 53 to move upward, the bottom connecting block 53 comes into contact with the square plate 412 to ensure that the position of the crossbar 52 does not change. When the square plate 412 moves upward, the rolling ball 416 moves upward. Under the action of the spiral groove 46, the outer bushing 42 can rotate in the opposite direction at one end. At this time, the hard alloy rolling head of the ultrasonic rolling mechanism 2 compacts the molten material at another position. When the square plate 412 drives the ball 416 to slide out from the inside of the spiral groove 46 and slide to the position of the longitudinal groove 45, the crossbar 52 slides out from the surface of the bottom connecting block 53. Under the action of the weight of the counterweight 514, the crossbar 52 can slide against the bottom surface of the bottom connecting block 53, thereby causing the ultrasonic rolling mechanism 2 to move away from the ring in the upward direction until the crossbar 52 moves to the initial position under the drive of the weight of the counterweight 514. During the upward movement of the square plate 412, when the bottom surface of the square plate 412 contacts the bottom surface of the trapezoidal plate 78, the trapezoidal plate 78 can drive the positioning rod 710 to rotate, thereby avoiding the movement of the square plate 412. After the square plate 412 moves to the initial position, the trapezoidal plate 78 slides off the surface of the square plate 412 and moves in the opposite direction to reset under the action of gravity until the second stop 715 and the positioning rod 710 abut against each other. At this time, the ultrasonic rolling process of light metal is completed. As the square plate 412 is about to move to the top position, after the square plate 412 contacts the top of the L-shaped tie rod 68, it will drive the L-shaped tie rod 68 to move upward. The L-shaped tie rod 68 will drive the rectangular block 69 to move synchronously. When the rectangular block 69 moves, it will apply a force to the diagonal brace plate 63, which will cause the diagonal brace plate 63 to slide out from the inside of the triangular groove 65. Under the action of the elastic potential energy of the spring 64, the L-shaped rod 62 can be reset.
