DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also belong to the protection scope of the present application.

[0036] The positioning device of the 3D printer provided in the embodiments of the present application solves the problem that the pushing plate needs to occupy a separate space to push the powder, and realizes the reasonable application of the space of the 3D printer.

[0037] The technical solutions in the embodiments of the present application are to solve the above technical problems, and the general idea is as follows:

[0038] 3D printing is printed by a 3D printer. When printing 3D metal materials, metal powder is usually printed by a laser nozzle to make the metal powder into a finished product. In the complex metal printing process, multi-level additive manufacturing is required. In the additive manufacturing process, the metal powder needs to be laid multiple times by using a push plate. The powder is laid according to the rule of printing one layer and laying one layer of powder. However, when the existing push plate pushes the powder, the push plate needs to occupy a separate space to push the powder, which increases the overall redundant volume of the 3D printer, and is not conducive to the rational application of the space of the 3D printer.

[0039] It is found through research that, as shown in Figures 1-6 by setting a pushing component and two pushing plates on the pushing component, the pushing component forms a material moving area to push the powder, moves the powder to be laid from the inside of the pushing frame to the inside of the printing frame, realizes the laying of the powder in the printing area of the printing frame, and further realizes the multi-level printing operation of 3D printing. The problem that the push plate needs to occupy a separate space to push the powder is solved, and the rational application of the space of the 3D printer is realized.

[0040] In order to better understand the above technical solutions, the above technical solutions will be described in detail in combination with the drawings of the specification and the specific embodiments.

[0041] Embodiment:

[0043] The inside of the rack 1 is provided with a pushing frame 2 and a printing frame 3;

[0044] The control component 12 is located above the printing frame 3 and controls the nozzle 121 to print;

[0045] The inside of the pushing frame 2 is provided with a material plate one 20, and the material plate one 20 vertically slides along the inner side wall of the pushing frame 2 through a cylinder one 21, and pushes the powder on the material plate one 20;

[0046] The inside of the printing frame 3 is provided with a material plate two 30, and the material plate two 30 vertically slides along the inner side wall of the printing frame 3 through a cylinder two 31, and forms a printing area 32 with the inner side wall of the printing frame 3. The printing area 32 is used for laying powder;

[0047] The side of the pushing frame 2 and the printing frame 3 close to each other is attached, and the pushing frame 2 and the printing frame 3 are the same;

[0048] The inside of the rack 1 is provided with two blocks 13, which are located on both sides of the rack 1 and form positioning cavities with the rack 1, which are matched with the frame opening of the pushing frame 2, and the pushing assembly 5 is installed in the positioning cavity, and the pushing assembly 5 slides in the positioning cavity through the telescopic piece 11 and is attached to the two blocks 13, and the telescopic piece 11 is used to control the paving of the pushing assembly 5;

[0049] The pushing assembly 5 is provided with two pushing plates 50 on one side close to the pushing frame 2, and the pushing assembly 5 forms a material moving area 51 with the two blocks 13 through the two pushing plates 50;

[0050] The material moving area 51 is matched with the frame opening of the pushing frame 2.

[0051] By setting the pushing assembly 5 and the two pushing plates 50 on the pushing assembly 5, the material moving area 51 formed by the pushing assembly 5 pushes the powder, and the powder to be paved is moved from the inside of the pushing frame 2 to the inside of the printing frame 3, realizing the paving of the powder in the printing area 32 of the printing frame 3, and realizing the multi-level printing operation of 3D printing, solving the problem that the pushing plate needs to occupy a separate space to push the powder, and realizing the reasonable application of the space of the 3D printer;

[0052] At the same time, the two pushing plates 50 form a material moving area 51 on the pushing assembly 5, and the powder to be pushed is always located in the inside of the material moving area 51 when the pushing assembly 5 pushes the powder in the pushing frame 2, and the powder in the pushing process is limited in the material moving area 51 by the pushing assembly 5, so that the material moving area 51 can effectively prevent the powder from splashing and flying out of the printing frame 3 during the pushing process, and the problem of affecting the 3D printing operation;

[0053] The whole process uses the pushing assembly 5 to position the powder, which can efficiently push the powder in the pushing frame 2 into the printing frame 3, realizing the subsequent 3D metal printing operation.

[0054] The two pushing plates 50 are integrally formed with the pushing assembly 5, which is convenient for the overall processing of the pushing assembly 5.

[0055] The fixed end of the telescopic piece 11 is located on the outside of the rack 1 and is fixedly connected with the rack 1, the moving end of the telescopic piece 11 penetrates through the rack 1 and is fixedly connected with the pushing assembly 5, and the pushing assembly 5 is controlled to approach or move away from the printing frame;

[0056] When the pushing plate 50 is located above the pushing frame 2, the side of the pushing plate 50 away from the printing frame 3 is in contact with the inner wall of the rack 1.

[0057] By setting the telescopic part 11 and the pushing assembly 5, and setting the fixed end of the telescopic part 11 on the outer side of the rack 1, when the pushing plate 50 is controlled to be above the pushing frame 2, the end of the pushing plate 50, which is provided with the telescopic part 11, is in contact with the rack 1, further improving the rational use of the space of the rack 1.

[0058] Specifically, the telescopic part 11 can be an electric telescopic rod.

[0059] The rack 1 is further provided with a receiving frame 4, which is located on the side of the printing frame 3 away from the pushing frame 2 and is attached to the printing frame 3.

[0060] The receiving frame 4 is provided with a falling block 40 inside, the rack 1 is provided with a discharge port 10, and the surface of the falling block 40 is inclined.

[0061] By setting the receiving frame 4 and the falling block 40 inside the receiving frame 4, the subsequent collection of powder materials can be facilitated.

[0062] During operation, first, the downward movement of the second material plate 30 is controlled by the second cylinder 31, and according to the thickness of the required printing level, the height of the printing area 32 between the second material plate 30 and the printing frame 3 is formed to meet the actual printing thickness requirement.

[0063] After the height of the printing area 32 is adjusted, the pushing assembly 5 is controlled by the telescopic part 11 to be located directly above the pushing frame 2, the moving area 51 formed by the pushing assembly 5 is consistent with the frame opening of the pushing frame 2, the first cylinder 21 is started to control the upward movement of the first material plate 20, at this time, the height of the upward movement of the first material plate 20 is consistent with the height of the printing area 32, the powder on the first material plate 20 is pushed upward into the moving area 51, then the powder in the moving area 51 is moved by the pushing assembly 5 controlled by the telescopic part 11, and when the powder is moved toward the printing frame 3 by the moving area 51, the powder in the moving area 51 gradually falls into the printing frame 3, and the powder that gradually falls into the printing frame 3 is laid by the pushing plate 50 on the pushing assembly 5 during the movement of the pushing assembly 5.

[0064] After the laying is completed, the powder laid in the printing frame 3 is laid again by the pushing plate 50 close to the receiving frame 4 during the process of the pushing assembly 5 returning to the original position, which enhances the flatness of the powder laid in the printing frame 3.

[0065] After the pushing assembly 5 returns to the original position, the newly laid powder layer is printed by the nozzle 121 controlled by the control assembly 12.

[0066] The above steps are repeated multiple times to complete multi-level metal printing.

[0067] It should be noted that the height of each descent of the cylinder two 31 is consistent with the height of each rise of the cylinder one 21, and the amount of powder pushed by the material moving area 51 and the capacity of the printing area 32 are consistent, which is convenient for the laying of the powder.

[0068] In summary, compared with the prior art, the following beneficial effects are achieved:

[0069] 1、By setting the pushing assembly 5, and setting two pushing plates 50 on the pushing assembly 5, the pushing assembly 5 forms a material moving area 51 to push the powder, and the powder to be laid is moved from the inside of the pushing frame 2 to the inside of the printing frame 3, which realizes the laying of the powder in the printing area 32 of the printing frame 3, and further realizes the multi-level printing operation of 3D printing, solves the problem that the pushing plate needs to occupy a separate space to push the powder when the pushing plate pushes the powder, and realizes the reasonable application of the space of the 3D printer.

[0070] 2、At the same time, the two pushing plates 50 form a material moving area 51 on the pushing assembly 5, and when the pushing assembly 5 pushes the powder in the pushing frame 2, the powder to be pushed is always located in the inside of the material moving area 51, and the pushing assembly 5 limits the powder in the pushing process in the material moving area 51, so that when the pushing speed of the pushing assembly 5 is increased, the material moving area 51 can effectively prevent the powder from splashing and flying out of the printing frame 3 during the pushing process, and the problem that is not conducive to 3D printing operation.

[0071] 3、By setting the telescopic part 11 and the pushing assembly 5, and setting the fixed end of the telescopic part 11 on the outside of the rack 1, when the pushing plate 50 is located above the pushing frame 2, the end of the pushing plate 50 installed with the telescopic part 11 is in contact with the rack 1, which further improves the rational use of the space of the rack 1.
