Description

Technical Field

[0001] This utility model relates to the field of laser additive manufacturing technology, specifically to a laser additive anti-oxidation device. Background Technology

[0002] Additive manufacturing, also known as 3D printing, is a bottom-up material accumulation manufacturing method. Traditional parts manufacturing often uses subtractive manufacturing, such as a carpenter cutting and sanding wood into the desired shape – this is a type of subtractive manufacturing. Additive manufacturing, on the other hand, is a method of automatically adding materials (including liquids, powders, filaments, or blocks) to form a solid structure. Just like using a 3D printer, the material is "printed" layer by layer from the bottom up; this is additive manufacturing.

[0003] Currently, additive manufacturing can be used in aerospace, marine, nuclear power, medical, automotive, mold, and high-end tool manufacturing fields. However, laser additive manufacturing products may be oxidized after production, resulting in a decline in product quality. Therefore, anti-oxidation treatment is required. Thus, there is a need to provide a laser additive anti-oxidation device to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model embodiment is to provide a laser additive anti-oxidation device to solve the problems in the background technology mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A laser additive manufacturing anti-oxidation device, comprising:

[0007] The body, wherein a placement rack is installed inside the body;

[0008] The spraying unit, installed inside the machine, is used to spray the laser additive manufacturing products on the placement rack;

[0009] The rotating unit is rotatably connected to the machine body and the placement rack, and is used to drive the placement rack to rotate;

[0010] The reciprocating unit is mounted on the spraying unit at one end and rotatably connected to the rotating unit at the other end. It is used to drive the spraying unit to rotate alternately in both directions within the machine body under the action of the rotating unit.

[0011] Compared with the prior art, the present invention has the following advantages: The present invention provides a spraying unit installed inside the machine body for spraying laser additive manufacturing products on the placement rack; a rotating unit rotatably connected inside the machine body and connected to the placement rack for driving the placement rack to rotate; and a reciprocating unit, with one end installed on the spraying unit and the other end rotatably connected to the rotating unit, for driving the spraying unit to rotate alternately in both directions inside the machine body under the action of the rotating unit.

[0012] When performing anti-oxidation treatment on laser additive manufactured products, the product is placed on a mounting rack, and the clamping rod is rotated to secure it. The spraying unit is then activated, spraying an anti-oxidant onto the surface of the product, thus achieving anti-oxidation treatment. The rotating unit then rotates the mounting rack within the machine, causing the product to rotate synchronously, improving the uniformity of the spraying. Furthermore, the reciprocating unit, driven by the rotating unit, alternates between forward and reverse rotation, increasing the spraying range and further enhancing the uniformity of the anti-oxidant coating, thereby effectively improving the quality of the laser additive manufactured product.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] See Figures 1-3 A laser additive manufacturing anti-oxidation device, comprising:

[0021] Body 1, wherein a placement rack 11 is installed inside the body 1;

[0022] Spraying unit 2, installed inside the machine body 1, is used to spray the laser additive manufacturing products on the placement rack 11;

[0023] The rotating unit 3 is rotatably connected inside the body 1 and connected to the placement rack 11, and is used to drive the placement rack 11 to rotate.

[0024] The reciprocating unit 4 is mounted on the spraying unit 2 at one end and rotatably connected to the rotating unit 3 at the other end. It is used to drive the spraying unit 2 to rotate alternately in the forward and reverse directions inside the machine body 1 under the action of the rotating unit 3.

[0025] In an embodiment of this invention, when performing anti-oxidation treatment on a laser additive manufactured product, the product is placed on a placement rack 11, and the clamping rod 5 is rotated to fix the product within the placement rack 11. The spraying unit 2 is then activated, spraying an anti-oxidant onto the surface of the laser additive manufactured product, thereby performing anti-oxidation treatment.

[0026] The rotating unit 3 is activated, which drives the placement frame 11 to rotate within the machine body 1. This allows the placement frame 11 to synchronously rotate the laser additive manufacturing product, thereby improving the uniformity of the coating applied by the spraying unit 2. Furthermore, the reciprocating unit 4, under the action of the rotating unit 3, drives the spraying unit 2 to rotate alternately in both directions, increasing the coating range of the spraying unit 2 on the laser additive manufacturing product and further improving the uniformity of the anti-oxidant coating on the surface of the laser additive manufacturing product.

[0027] In one embodiment of this utility model, such as Figure 2 As shown, the spraying unit 2 includes:

[0028] The spraying box 21 is installed on the side of the machine body 1, and the spraying pump 211 is installed inside.

[0029] The support frame 22 is installed inside the machine body 1, and the surface is equipped with a spray head 23. The spray head 23 is connected to the output end of the spray pump 211 through a conduit.

[0030] In this embodiment, the spray box 21 is installed on the side of the machine body 1, and a spray pump 211 is installed inside it; the support frame 22 is installed inside the machine body 1, and a nozzle 23 is installed on its surface. The nozzle 23 is connected to the output end of the spray pump 211 through a conduit.

[0031] When performing anti-oxidation treatment on laser additive manufacturing products, the laser additive manufacturing products are placed on the placement rack 11, an anti-oxidant is added to the spraying box 21, and the spraying pump 211 is turned on. The output end of the spraying pump 211 can introduce the anti-oxidant in the spraying box 21 into the nozzle 23 through the conduit, and spray it from the nozzle 23 onto the surface of the laser additive manufacturing products, thereby performing anti-oxidation treatment on the laser additive manufacturing products.

[0032] Multiple sets of spray nozzles 23 can be installed in the spraying unit 2, and no single set is specified here.

[0033] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the rotating unit 3 includes:

[0034] The bracket 31 is fixed inside the body 1, and the drive component 32 is installed on the side;

[0035] The rotating rod 33 is rotatably connected inside the bracket 31, its surface is connected to the placement rack 11, and its end is connected to the output end of the drive unit 32.

[0036] In this embodiment, the bracket 31 is fixed inside the body 1, and a drive component 32 is installed on the side; the rotating rod 33 is rotatably connected inside the bracket 31, its surface is connected to the placement frame 11, and its end is connected to the output end of the drive component 32.

[0037] When the drive unit 32 is activated, the output end of the drive unit 32 can drive the rotating rod 33 to rotate within the bracket 31. During the rotation of the rotating rod 33, the mounting frame 11 on its surface can rotate, thereby enabling the mounting frame 11 to rotate the laser additive manufacturing product inside it. This facilitates the spraying unit 2 to spray the laser additive manufacturing product at different angles, improving the uniformity of the laser additive manufacturing product spraying.

[0038] The driving component 32 in the rotating unit 3 can be an electric motor or a pneumatic motor, which can drive the rotating rod 33 to rotate stably within the bracket 31.

[0039] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the round-trip unit 4 includes:

[0040] The support plate 41 is fixed inside the body 1, and a rotating shaft 42 is rotatably connected inside it. The support frame 22 is installed on the surface of the rotating shaft 42.

[0041] A rotating frame 43 is mounted on the surface of a rotating shaft 42, and a groove 44 is provided on the surface.

[0042] A rotating frame 45 is mounted on a rotating rod 33, and a rotating column 46 is mounted on its surface. The rotating column 46 is slidably connected in a groove 44.

[0043] In this embodiment, the support plate 41 is fixed inside the body 1, and a rotating shaft 42 is rotatably connected inside it. The support frame 22 is installed on the surface of the rotating shaft 42. The rotating frame 43 is installed on the surface of the rotating shaft 42, and a sliding groove 44 is provided on the surface. The rotating frame 45 is installed on the rotating rod 33, and a rotating column 46 is installed on the surface. The rotating column 46 is slidably connected in the sliding groove 44.

[0044] When the rotating rod 33 rotates, it can drive the rotating frame 45 on its surface to rotate synchronously. Thus, the rotating frame 45 can drive the rotating column 46 to rotate. Since the rotating column 46 and the sliding groove 44 are slidably connected, the rotating frame 43 can drive the rotating shaft 42 to reciprocate and alternately rotate within the support plate 41 under the action of the rotating column 46 and the sliding groove 44. In turn, the rotating shaft 42 can drive the nozzle 23 to rotate alternately in both directions through its connection with the support frame 22, thereby increasing the spraying range of the nozzle 23 on the laser additive manufacturing product and improving the uniformity of the anti-oxidant sprayed on the surface of the laser additive manufacturing product.

[0045] Rolling wheels can also be installed on the surface of the rotating column 46 in the reciprocating unit 4. The rolling wheels are rolledly connected to the inner wall of the slide groove 44, so that the rotating column 46 can slide stably in the slide groove 44 by means of the rolling wheels.

[0046] In one embodiment of this utility model, such as Figure 3 As shown, the placement rack 11 is connected to a clamping rod 5 by a thread.

[0047] In this embodiment, the placement rack 11 is threadedly connected to clamping rods 5, and at least four sets of clamping rods 5 are installed. After the laser additive manufacturing product is placed in the placement rack 11, the clamping rods 5 are rotated, causing them to rotate and slide within the placement rack 11 until their ends slide to contact the surface of the laser additive manufacturing product, thereby fixing the product within the placement rack 11. Furthermore, laser additive manufacturing products can be placed on both sides of the placement rack 11, allowing for simultaneous anti-oxidation treatment of two sets of products, thus improving the efficiency of the anti-oxidation treatment.

[0048] The working principle of this invention is as follows: When performing anti-oxidation treatment on laser additive manufactured products, the laser additive manufactured products are placed on the placement rack 11, and the clamping rod 5 is rotated, causing the clamping rod 5 to rotate and slide within the placement rack 11 until the end of the clamping rod 5 slides to contact the surface of the laser additive manufactured product, thereby fixing the laser additive manufactured product within the placement rack 11. By adding an antioxidant to the spraying box 21 and turning on the spraying pump 211, the output end of the spraying pump 211 can introduce the antioxidant in the spraying box 21 into the nozzle 23 through a conduit, and spray it from the nozzle 23 onto the surface of the laser additive manufactured product, thereby performing anti-oxidation treatment on the laser additive manufactured product.

[0049] When the drive unit 32 is activated, the output end of the drive unit 32 can drive the rotating rod 33 to rotate within the bracket 31. During the rotation of the rotating rod 33, the mounting frame 11 on its surface can rotate, thereby enabling the mounting frame 11 to rotate the laser additive manufacturing product inside it. This facilitates the spraying unit 2 to spray the laser additive manufacturing product at different angles, improving the uniformity of the laser additive manufacturing product spraying.

[0050] When the rotating rod 33 rotates, it can drive the rotating frame 45 on its surface to rotate synchronously. Thus, the rotating frame 45 can drive the rotating column 46 to rotate. Since the rotating column 46 and the sliding groove 44 are slidably connected, the rotating frame 43 can drive the rotating shaft 42 to reciprocate and alternately rotate within the support plate 41 under the action of the rotating column 46 and the sliding groove 44. In turn, the rotating shaft 42 can drive the nozzle 23 to rotate alternately in both directions through its connection with the support frame 22, thereby increasing the spraying range of the nozzle 23 on the laser additive manufacturing product and further improving the uniformity of the anti-oxidant sprayed on the surface of the laser additive manufacturing product.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
