Description

Technical Field

[0001] The present invention relates to the technical field of additive manufacturing auxiliary equipment, and specifically relates to a multifunctional auxiliary equipment for laser additive manufacturing. Background Art

[0002] Laser additive manufacturing technology, also known as laser 3D printing technology, is a new type of rapid prototyping technology developed by integrating multiple interdisciplinary and technologies. It mainly uses computer-aided design to slice a three-dimensional solid model into two-dimensional layers, and then discretize it into one-dimensional lines. The laser cladding technology is used to stack points one by one, and finally realizes the laser manufacturing technology of three-dimensional solid parts; laser additive manufacturing equipment does not require traditional tools, jigs and multiple processing procedures. It can quickly and precisely manufacture parts with any complex shape on one device, thus realizing the "free manufacturing" of parts, solving the forming of many complex structure parts, greatly reducing the processing procedures and shortening the processing cycle.

[0003] In the prior art, such as a multifunctional auxiliary equipment for laser additive manufacturing with the publication number CN217514566U, the adjustable operating platform of the laser additive manufacturing equipment includes: a bottom plate, and an operating platform located on one side above the bottom plate; one side of the operating platform is fixedly connected with an angle adjustment component for adjusting the angle of the operating platform; the angle adjustment component includes: a driving member; and a bracket fixedly connected with the driving member; a top rod is slidably connected to the bracket; and a contact head fixedly connected to one side of the top rod; a convex block is fixedly connected to one side below the top rod. By setting the moving component, the device can move the horizontal position of the operating platform. By combining the angle adjustment component and the moving component, the device can adjust the angle and horizontal position of the operating platform, greatly improving the adjustment ability of the device and being more suitable for popularization and use.

[0004] However, in the actual use process, since the horizontal position of the operating platform needs to be moved by combining the angle adjustment component and the moving component to adjust the angle and horizontal position of the operating platform, manual operation is required during this operation process, which is prone to operation errors and cannot automatically and continuously achieve the dwell processing at any horizontal position; moreover, the overall functionality of the operating platform is single, lacking a positioning structure after dwelling, resulting in affecting the overall rigidity and stability of the platform.

[0005] Therefore, the present invention proposes a multifunctional auxiliary equipment for laser additive manufacturing to solve the problems that the prior art cannot automatically and continuously achieve the dwell processing at any horizontal position and has a single functionality, and can perform the dwell processing at any horizontal position for the additive continuously, meeting the requirements of convenient operation and realizing the integrated auxiliary cleaning of the surface of the operating platform.

Detailed implementation manners

[0019] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Example 1, please refer to Figure 1-17, the present invention provides a technical solution: a multifunctional auxiliary equipment for laser additive manufacturing, including a support table 1 and a base 11 fixedly connected to the upper end. An operation platform 12 is installed on the upper end of the base 11. A rotating groove 110 is opened on the inner wall of the base 11. A rotating cylinder 2 is rotatably connected to the inner wall of the rotating groove 110. An adjusting mechanism is arranged between the base 11 and the rotating cylinder 2. The adjusting mechanism includes a rotating component and a horizontal moving component. The outer surface of the rotating cylinder 2 is rotatably connected to the inner wall of the operation platform 12. A swinging groove plate 3 is integrally formed on the upper side surface of the rotating cylinder 2. Side grooves 30 are respectively opened on the inner walls on both sides of the swinging groove plate 3. A folding cleaning component is arranged inside the side grooves 30. The folding cleaning component includes a sliding side block 5, an upper swinging arm 512, a lower swinging arm 513 and an extended folding arm 522. An activity groove 300 is opened on the upper surface of the swinging groove plate 3. A threaded block is slidably connected to the inner surface of the activity groove 300. A placement table 6 is fixedly connected to the upper end of the threaded block. The lower surface of the placement table 6 is fixedly connected to the upper surface of the sliding side block 5. A storage locking component is arranged on the surfaces of the upper swinging arm 512, the lower swinging arm 513 and the extended folding arm 522; the outer surface of the sliding side block 5 is slidably connected to the inner wall of the side groove 30. A first hinge block 51 is fixedly connected to the outer surface of the sliding side block 5. The first hinge block 51 is slidably installed on the inner wall of the side groove 30. A second hinge block 52 is fixedly installed on the inner wall on the other side of the side groove 30. A first brush plate 514 is detachably connected to the lower surface of the lower swinging arm 513. A second brush plate 523 is detachably connected to the lower surface on the side of the extended folding arm 522 close to the second hinge block 52; In this embodiment, the operation platform and the placement table are used to place the laser additive. This equipment not only realizes the continuous and automatic positioning processing of the laser additive on the horizontal plane. Specifically, in order to realize the continuous stationary processing of the laser additive at any horizontal position, by driving the rotating component, the rotation of the rotating cylinder 2 is controlled, and the swinging groove plate 3 formed as an integral structure with the rotating cylinder 2 rotates synchronously. When the placement table 6 is at a certain position without moving, the swinging groove plate 3 drives the additive placed on the placement table 6 to move horizontally. When it is necessary to change the horizontal position of the additive, by driving the horizontal moving component, the entire placement table 6 is driven to move on the inner wall of the activity groove 300. In this way, the continuous movement and stationary processing of the additive at any horizontal position can be realized, ensuring the continuity and automation of the equipment processing; and through the side grooves opened on both sides of the swinging groove plate, the folding cleaning component is built in, realizing the versatility of the swinging groove plate, facilitating the self-cleaning of the placement table surface, and realizing the integrated operation of processing and cleaning; further solving the problems that the prior art cannot automatically and continuously realize the stationary processing at any horizontal position and has a single function.

[0021] Embodiment Two, referring to the appendix Figure 1-17, on the basis of Embodiment 1, in order to realize the connection between the folding cleaning component and the swinging groove plate 3 and ensure the integrated design of processing and cleaning of the equipment during extension: the outer surface of the sliding side block 5 is slidably connected to the inner wall of the side groove 30, and the outer surface of the sliding side block 5 is fixedly connected to a first hinge block 51. The first hinge block 51 is slidably installed on the inner wall of the side groove 30. A second hinge block 52 is fixedly installed on the inner wall of the other side of the side groove 30. A first pin shaft 511 is rotatably installed on the first hinge block 51, and a second pin shaft 521 is rotatably installed on the second hinge block 52. The outer surface of the first pin shaft 511 is fixedly connected to one end of an upper swing arm 512 and a lower swing arm 513. The outer surface of the second pin shaft 521 is fixedly connected to one end of an extended folding arm 522; one ends of the upper swing arm 512 and the lower swing arm 513 far from the first pin shaft 511 are rotatably connected to a third pin shaft 53, and the surface of the third pin shaft 53 is rotatably connected to the inner wall of one end of the extended folding arm 522 far from the second pin shaft 521. The upper swing arm 512 and the lower swing arm 513 are arranged in parallel, and the extended folding arm 522 is movably installed between the upper swing arm 512 and the lower swing arm 513; a first brush plate 514 is detachably connected to the lower surface of the lower swing arm 513, and a second brush plate 523 is detachably connected to the lower surface of one side of the extended folding arm 522 close to the second hinge block 52; Corresponding side grooves 30 are respectively formed on the inner walls of both sides of the swinging groove plate 3. The first hinge block 51 is connected to the surface of the sliding side block 5. The first hinge block 51 is rotatably connected to the upper swing arm 512 and the lower swing arm 513 through the first pin shaft 511. One end of the extended folding arm 522 is connected by the third pin shaft 53 at the middle position between the parallel upper swing arm 512 and the lower swing arm 513. When the sliding side block 5 horizontally moves on the inner wall of the side groove 30, the upper swing arm 512 and the lower swing arm 513 are immediately pushed outwards. At this time, one end of the extended folding arm 522 is pulled by the third pin shaft 53 and pulled out at a certain angle. In this way, as long as the sliding side block 5 continuously slides on the inner wall of the side groove 30, the upper swing arm 512, the lower swing arm 513 and the extended folding arm 522 form a folding structure. Then, the surface of the operation platform 12 can be automatically cleaned through the connected first brush plate 514 and second brush plate 523, further solving the problem of the single overall functionality of the operation platform.

[0022] Embodiment 3, referring to the appendix Figure 1-17, on the basis of the second embodiment, in order to achieve the locking when the folding cleaning component is recycled: the storage locking component includes a guiding column 7, which is rotatably installed on the inner wall of the extending folding arm 522. A limiting hook block 71 is fixedly connected to the outer surface of the guiding column 7. The limiting hook block 71 is integrally formed with the arm plate in a circular ring shape, and both ends of the limiting hook block 71 are respectively provided with rounded corners. A reserved groove 70 is opened on the inner wall of one end of the guiding column 7. Both ends of the reserved groove 70 are respectively connected through a relief groove 700. The relief groove 700 is opened on the surface of the guiding column 7. A rotating handle 72 is rotatably connected to the inner surface of the reserved groove 70. A gear 721 is fixedly connected to the outer surface of the rotating handle 72. Locking plug rods 722 are meshed and rotated on both outer surfaces of the gear 721. The storage locking component further includes a fixing block 8. The fixing block 8 is integrally in an "F"-shaped plate structure. A positioning hoop 81 is fixedly connected to the inner surface of the fixing block 8. There are two groups of fixing blocks 8, and the two groups of fixing blocks 8 are respectively fixedly installed on the surfaces of the upper swing arm 512 and the lower swing arm 513. A slot 80 is opened on the inner wall of the fixing block 8. The inner surface of the slot 80 is movably inserted with the outer surface of the locking plug rod 722; Before the laser additive manufacturing starts or after it is completed, at this time, the sliding side block 5 is at the end of the side groove 30 closest to the rotating gear 423, and at this time, the upper swing arm 512, the lower swing arm 513 and the extending folding arm 522 are folded and recycled, and the whole is stored in the inner side of the side groove 30 in a "one"-shaped structure. When it is necessary to lock the upper swing arm 512, the lower swing arm 513 and the extending folding arm 522, specifically, pinch the surface of the guiding column 7 with the thumb and index finger, and then rotate it counterclockwise by 90°. It should be noted that when it is in the unlocked state, the guiding column 7 and the limiting hook block 71 always remain parallel to the extending folding arm 522. Refer to Figure 11 As shown; when the limiting hook block 71 rotates to a state perpendicular to the extending folding arm 522, both ends of the limiting hook block 71 enter the inner side of the fixing block 8. At this time, the rounded corner at one end of the limiting hook block 71 abuts against the inner side of the positioning hoop 81. The positioning hoop 81 undergoes elastic deformation under the external force of the rounded corner. When the rounded corner position of the limiting hook block 71 completely arrives, the positioning hoop 81 forms a hugging reaction on the rounded corner end of the limiting hook block 71, so as to achieve the preliminary locking of the position of the limiting hook block 71; After the position of the limiting hook block 71 is preliminarily locked, release the finger pinching the guiding column 7, and pinch the rotating handle 72 with three fingers and rotate it counterclockwise. At this time, the gear 721 rotates synchronously and is meshed with the two locking plug rods 722. Under the limiting action of the relief groove 700, the two locking plug rods 722 move relatively to both sides respectively. After the rotating handle 72 rotates a certain angle, both ends of the locking plug rod 722 are respectively inserted into the inner side of the slot 80. Refer to Figure 7 、 Figure 8 、 Figure 9As shown, the locking of the folding cleaning component can be achieved in this way, avoiding loosening during transportation and further ensuring the functionality of the auxiliary equipment.

[0023] Embodiment 4. Refer to the attached Figure 1-17 On the basis of Embodiment 3, in order to achieve continuous dwell machining at any horizontal position of the laser additive: The rotating component includes a servo motor 4, which is fixedly installed on the lower surface of the base 11. A shaft rod 41 is fixedly connected to the output shaft of the servo motor 4. The outer surface of the shaft rod 41 is rotatably connected to the inner wall of the base 11. An active rotating gear 411 is fixedly connected to the upper outer surface of the shaft rod 41. A driven gear ring 412 is meshed and rotated on one side outer surface of the active rotating gear 411. The inner ring surface of the driven gear ring 412 is fixedly connected to the lower outer surface of the rotating cylinder 2; The horizontal moving component includes a limit groove plate 42, which is integrally in a "U"-shaped plate structure. The limit groove plate 42 is fixedly installed on the inner surface of the rotating cylinder 2. A lifting groove 420 is opened on the inner wall of the limit groove plate 42. A lifting block 4221 is slidably connected to the inner surface of the lifting groove 420. A lifting tooth plate 422 is fixedly connected to the outer surface of the lifting block 4221. An electric telescopic rod 421 is fixedly connected to the lower end of the lifting tooth plate 422. The lower outer surface of the electric telescopic rod 421 is fixedly connected to the bottom surface of the limit groove plate 42; One side surface of the lifting tooth plate 422 is provided with an arc surface adapted to the inner ring surface of the rotating cylinder 2, and the other side surface of the lifting tooth plate 422 is provided as a tooth surface. A rotating gear 423 is meshed and rotated on the tooth surface of the lifting tooth plate 422. A threaded rod 424 is fixedly connected to the central inner surface of the rotating gear 423. The outer surface of the threaded rod 424 is rotatably connected to the inner walls of the rotating cylinder 2 and the swinging groove plate 3 respectively. The outer surface of the threaded rod 424 is threadedly connected to the inner wall of the threaded block; The laser additive manufacturing material is stably installed on the placement table 6. When continuous horizontal movement of the additive is required, the servo motor 4 is controlled to start. Its output shaft rotates and drives the shaft rod 41 to rotate synchronously. The driving rotating gear 411 rotates. At this time, the driven gear ring 412 is engaged with the external teeth of the driving rotating gear 411. In this way, the driven gear ring 412 drives the whole rotating cylinder 2 to rotate. At this time, the swinging groove plate 3 integrated with the rotating cylinder 2 rotates synchronously. When the placement table 6 is in a certain position without moving, the swinging groove plate 3 drives the additive placed on the placement table 6 to move horizontally; when the horizontal position of the additive needs to be changed, there is no need for manual operation. Only the electric telescopic rod 421 at the bottom of the limit groove plate 42 needs to be controlled to expand and contract. At this time, the piston rod at the output end of the electric telescopic rod 421 drives the lifting tooth plate 422 to move longitudinally on the inner wall of the lifting groove 420, and through the adaptive sliding of the lifting block 4221 and the lifting groove 420, the stability of the longitudinal movement of the lifting tooth plate 422 is ensured. The arc surface of the lifting tooth plate 422 is adaptively slid with the inner wall of the rotating cylinder 2, and the tooth surface is engaged with the rotating gear 423. In this way, the rotating gear 423 rotates, and the threaded rod 424 rotates synchronously. Under the double limit of thread adaptation and the activity groove 300, the threaded block drives the whole placement table 6 to move on the inner wall of the activity groove 300. In this way, continuous movement and stationary processing of the additive at any horizontal position can be realized, ensuring the continuity and automation of equipment processing; it should be noted that the lifting tooth plate 422 will not affect the rotation of the rotating cylinder 2 and the swinging groove plate 3 during the lifting process. In this way, the problems of the prior art that cannot automatically and continuously realize stationary processing at any horizontal position and have a single function are further solved, improving the accuracy and working efficiency of the laser additive manufacturing technology.

[0024] Embodiment 5. Refer to the attached Figure 1-17 , on the basis of Embodiment 4, the present invention also provides a usage method of an auxiliary equipment for multi-functional laser additive manufacturing, including the following steps: Step 1: Corresponding side grooves 30 are respectively opened on the inner walls on both sides of the swinging groove plate 3. The hinge block 51 is connected to the surface of the sliding side block 5. The hinge block 51 is rotationally connected to the upper swinging arm 512 and the lower swinging arm 513 through a pin 511. The middle positions of the parallel upper swinging arm 512 and the lower swinging arm 513 are connected to one end of the extended folding arm 522 through a pin 53. When the sliding side block 5 moves horizontally on the inner wall of the side groove 30, the upper swinging arm 512 and the lower swinging arm 513 are immediately pushed outwards. At this time, one end of the extended folding arm 522 is pulled by the pin 53 and pulled out at a certain angle. In this way, as long as the sliding side block 5 continuously slides on the inner wall of the side groove 30, and the upper swinging arm 512, the lower swinging arm 513 and the extended folding arm 522 form a folding structure, then the surface of the operation platform 12 can be automatically cleaned by the connected brush plate 514 and brush plate 523; Step 2: Before or after the laser additive manufacturing starts, the sliding side block 5 is at the end of the side groove 30 closest to the rotating gear 423. At this time, the upper swing arm 512, the lower swing arm 513 and the extended folding arm 522 are folded and retracted, and the whole is stored in the inner side of the side groove 30 in a "one" - shaped structure. Pinch the surface of the guide post 7 with the thumb and index finger, and then rotate counterclockwise by 90°. It should be noted that when it is in the unlocked state, the guide post 7 and the limit hook block 71 always maintain a parallel position with the extended folding arm 522. Refer to Figure 11 as shown; when the limit hook block 71 rotates to a state perpendicular to the extended folding arm 522, the two ends of the limit hook block 71 enter the inner side of the fixed block 8. At this time, the rounded corner at one end of the limit hook block 71 abuts against the inner side of the positioning hoop 81, and the positioning hoop 81 undergoes elastic deformation under the external force of the rounded corner. When the rounded corner position of the limit hook block 71 reaches completely, the positioning hoop 81 forms a clamping reaction on the rounded corner end of the limit hook block 71, thus realizing the preliminary locking of the position of the limit hook block 71; Step 3: After the position of the limit hook block 71 is preliminarily locked, release the finger pinching the guide post 7, and pinch the rotating handle 72 with three fingers and rotate counterclockwise. At this time, the gear 721 rotates synchronously and meshes with the two locking insertion rods 722 on both sides. Under the limiting action of the avoidance groove 700, the two groups of locking insertion rods 722 move relatively to both sides respectively. When the rotating handle 72 rotates a certain angle, the two ends of the locking insertion rod 722 are respectively inserted into the inner side of the insertion slot 80, so as to realize the locking of the folding cleaning assembly; Step 4: Stably install the laser additive manufacturing material on the placement table 6. When it is necessary to move the additive continuously in the horizontal position, control the servo motor 4 to start. Its output shaft rotates and drives the shaft rod 41 to rotate synchronously. The driving rotating gear 411 rotates. At this time, the driven gear ring 412 meshes with the external teeth of the driving rotating gear 411. In this way, the driven gear ring 412 drives the whole rotating cylinder 2 to rotate. At this time, the swing groove plate 3 integrated with the rotating cylinder 2 rotates synchronously. When the placement table 6 is at a certain position without moving, the swing groove plate 3 drives the additive placed on the placement table 6 to move horizontally; Step 5: When it is necessary to change the horizontal position of the additive, there is no need for manual operation. Only need to control the telescopic movement of the electric telescopic rod 421 at the bottom of the limit groove plate 42. At this time, the piston rod at the output end of the electric telescopic rod 421 drives the lifting tooth plate 422 to move longitudinally on the inner wall of the lifting groove 420, and through the adaptive sliding of the lifting block 4221 and the lifting groove 420, ensure the stability of the longitudinal movement of the lifting tooth plate 422. The arc surface of the lifting tooth plate 422 slides adaptively with the inner wall of the rotating cylinder 2, and the tooth surface meshes with the rotating gear 423. In this way, the rotating gear 423 rotates, and the threaded rod 424 rotates synchronously. Under the double - limit of thread adaptation and the activity groove 300, the threaded block drives the whole placement table 6 to move on the inner wall of the activity groove 300, so as to realize the continuous movement and stationary processing of the additive at any horizontal position.
