Description

Technical Field

[0001] This application relates to the field of metal additive manufacturing, and in particular to a vibration dust removal mechanism for metal additive manufacturing. Background Technology

[0002] Metal additive manufacturing, also known as metal 3D printing, is an advanced manufacturing technology that deposits metal powder layer by layer to form a three-dimensional solid. However, during the printing process, metal powder can easily remain in the internal pores of the printed part. This not only affects the quality of the printed part but can also cause inconvenience for subsequent processing and use. Traditional dust removal methods are often inefficient and difficult to completely remove the powder from inside the printed part. Therefore, developing a highly efficient, multi-angle vibration dust removal mechanism is particularly important. Utility Model Content

[0003] To address the above issues, this application provides a vibration dust removal mechanism for metal additive manufacturing.

[0004] The vibration dust removal mechanism for metal additive manufacturing provided in this application adopts the following technical solution:

[0005] A vibration dust removal mechanism for metal additive manufacturing includes: a support; a second housing mounted on the top surface of the support; a circular plate mounted on the top surface of the second housing; a platform mounted on the top surface of the circular plate; a first spring mounted between the circular plate and the support; a first housing mounted on the bottom surface of the support; and a vibration mechanism mounted inside the first housing. The vibration mechanism and the first housing are configured to be connected to each other so that the first housing can reciprocate up and down.

[0006] Preferably, the vibration mechanism includes two inverted L-shaped rods installed at both ends inside the first housing; a connecting plate installed between the two inverted L-shaped rods; a rectangular block installed vertically on the two inverted L-shaped rods; a second spring sleeved on the outside of the top rod between the inverted L-shaped rods and the rectangular block; an upper support plate and a lower support plate installed on the inverted L-shaped rods and the rectangular block, respectively; and a vertical rod installed between the upper support plate and the lower support plate.

[0007] Preferably, it further includes a third motor mounted on one of the inverted L-shaped rods; a circular grooved wheel connected to the output end of the third motor; a shaft mounted on the rectangular block; and a roller mounted on the shaft. The roller is disposed inside the circular grooved wheel, and the roller and the circular grooved wheel are configured to be in a mating connection.

[0008] Preferably, it also includes a second motor, installed inside the second housing; a rotating shaft connected to the output end of the second motor; and the top end of the rotating shaft passing through a circular plate and connected to the platform.

[0009] Preferably, it also includes a left-hand rotating rod and a right-hand rotating rod, which are respectively installed laterally at both ends of the bracket; and a first motor, the output end of which is connected to the right-hand rotating rod.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] The output of the third motor drives the circular grooved wheel to rotate. The rotation of the circular grooved wheel causes the roller to move inside the circular grooved wheel. The movement of the roller causes the shaft and the rectangular block on it, the connecting plate and another rectangular block to move vertically up and down. The up and down movement of the two rectangular blocks causes the top rods on them to move up and down. The movement of the two top rods causes the second housing to move upward. At the same time, the elasticity of the first spring can make the second housing drive the circular plate and platform to vibrate upward. When the metal printer is flipped face down, it causes the powder inside the metal print to fall off quickly, improving the dust removal efficiency. Attached Figure Description

The system includes a top rod 13, a second spring 14, a top rod 13, an upper support plate 18 and a lower support plate 15, an upper support plate 18 and a lower support plate 15, a vertical rod 16, a third motor 22, a third motor 22, a circular grooved wheel 21, a shaft 19, a rectangular block 23, a roller 20 ...1, a roller 20, a roller 20, a roller 2

[0019] The output of the third motor 22 drives the circular grooved wheel 21 to rotate. The rotation of the circular grooved wheel 21 drives the roller 20 to move inside the circular grooved wheel 21. The movement of the roller 20 drives the shaft 19 and the rectangular block 23 on it, the connecting plate 17 and another rectangular block 23 to move vertically up and down. The up and down movement of the two rectangular blocks 23 drives the top rod 13 on them to move up and down. The movement of the two top rods 13 drives the second housing 5 to move upward. At the same time, the elasticity of the first spring 7 enables the second housing 5 to drive the circular plate 6 and the platform 3 to move upward and vibrate. When the metal printer flips down, it causes the powder inside the metal print to fall off quickly, improving the dust removal efficiency.

[0020] Reference Figures 2-3 It also includes a second motor 10, which is installed inside the second housing 5, and a rotating shaft 11, which is connected to the output end of the second motor 10. The top end of the rotating shaft 11 passes through the circular plate 6 and is connected to the platform 3.

[0021] The output of the second motor 10 drives the rotating shaft 11 to rotate, and the rotation of the rotating shaft 11 drives the platform 3 to rotate, thereby realizing the adjustment of the rotation angle of the metal printed part on the top surface of the platform 3.

[0022] Reference Figure 1 It also includes a left rotating rod 2 and a right rotating rod 8, which are horizontally installed at both ends of the bracket 1, and a first motor 9, whose output end is connected to the right rotating rod 8;

[0023] The output of the first motor 9 drives the right rotating rod 8 to rotate, and the rotation of the right rotating rod 8 drives the bracket 1 and the left rotating rod 2 to rotate, thereby realizing the adjustment of the flipping angle of the metal printed part on the top surface of the platform 3.

[0024] The implementation principle of the vibration dust removal mechanism for metal additive manufacturing in this application embodiment is as follows: In use, the output of the first motor 9 drives the right rotating rod 8 to rotate. The rotation of the right rotating rod 8 drives the bracket 1 and the left rotating rod 2 to rotate, adjusting the flip angle of the metal printed part on the top surface of the platform 3. Then, the output of the second motor 10 drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the platform 3 to rotate circumferentially. Simultaneously, the output of the third motor 22 drives the circular grooved wheel 21 to rotate. The rotation of the circular grooved wheel 21 drives the roller 20 to rotate in the circular groove. The internal movement of the wheel 21 causes the roller 20 to drive the shaft 19 and its rectangular block 23, connecting plate 17 and another rectangular block 23 to move vertically up and down. The up and down movement of the two rectangular blocks 23 drives the top rod 13 on them to move up and down. The movement of the two top rods 13 drives the second housing 5 to move upward. At the same time, the elasticity of the first spring 7 enables the second housing 5 to drive the circular plate 6 and platform 3 to vibrate upward. When the metal printer flips down, it causes the powder inside the metal print to fall off quickly, improving dust removal efficiency.
