Description

Technical Field

[0001] This invention relates to the field of additive manufacturing technology, and in particular to a secondary powder cleaning tooling for additive manufacturing cabin parts. Background Technology

[0002] Additive manufacturing technology has become widely used in high-end manufacturing in recent years. It uses a high-energy beam to selectively sinter materials layer by layer according to a three-dimensional model to obtain parts. Cabin parts refer to parts with a circular or near-circular shape, possessing a certain wall thickness and diameter. Cabins manufactured using additive manufacturing technology typically have complex internal cavity structures. The powder in these cavities is usually cleaned along with the substrate after printing using a powder cleaning device. However, due to the complexity of the structure, some powder cannot be completely removed, requiring the part to be separated from the substrate for further cleaning. But because cabin parts are large, it is difficult to reattach them to the powder cleaning device. Therefore, secondary powder cleaning of cabin parts is mostly done manually, which is difficult and yields poor results. Utility Model Content

[0003] Based on the above analysis, the present invention aims to provide a secondary powder cleaning fixture for additive manufacturing cabin parts, in order to solve the problem that it is difficult to re-fix the cabin parts to the powder cleaning equipment after they are separated from the substrate.

[0004] The objective of this utility model is mainly achieved through the following technical solutions:

[0005] A secondary powder cleaning fixture for additive manufacturing cabin parts is used to mount the cabin parts onto a powder cleaning device for secondary powder cleaning. The fixture includes a support, a radial limiting and fixing mechanism, and an axial limiting and fixing mechanism. The support supports the cabin parts and can be fixedly connected to the powder cleaning device. The radial limiting and fixing mechanism is mounted on the support and can move on the support. The radial limiting and fixing mechanism is used to radially limit and fix cabin parts of different diameters. The axial limiting and fixing mechanism is mounted on the radial limiting and fixing mechanism and is used to radially limit and fix the cabin parts.

[0006] Furthermore, the radial limiting and fixing mechanism includes a limiting screw, one end of which is mounted on a support and can move on the support, thereby enabling the limiting screw to contact the outer surface of the cabin part; the other end of the limiting screw is connected to the axial limiting and fixing mechanism.

[0007] Furthermore, the axial limiting and fixing mechanism includes a pressure plate and a fastening bolt. The pressure plate passes through the limiting screw and can contact the end face of the cabin part. The fastening bolt is sleeved on the limiting screw and is threadedly connected to the limiting screw.

[0008] Furthermore, the tooling also includes a retainer for adjusting the position of the limiting screw on the support and keeping the limiting screw in contact with the outer surface of the cabin part.

[0009] Furthermore, the retainer includes a ring seat and a retaining screw, the ring seat being mounted on the support; the retaining screw is mounted on the ring seat and is capable of sliding radially along the ring seat.

[0010] Furthermore, the retaining screw and the limiting screw are arranged opposite to each other.

[0011] Furthermore, the retainer also includes a control bolt for adjusting the position of the retaining screw on the ring seat.

[0012] Furthermore, the control bolt is mounted on the ring seat and is rotatable relative to the ring seat.

[0013] Furthermore, the control bolt is sleeved on the retaining screw and threadedly connected to the retaining screw.

[0014] Furthermore, the support is provided with a sliding groove for installing a limiting screw.

[0015] The technical solution of this utility model can achieve at least one of the following effects:

[0016] (1) This utility model provides a secondary cleaning fixture for additive manufacturing cabin parts, including a support, a radial limiting and fixing mechanism, and an axial limiting and fixing mechanism. The support is used to support the cabin parts and can be fixedly connected to the cleaning equipment. The radial limiting and fixing mechanism is installed on the support and can move on the support. The radial limiting and fixing mechanism is used to radially limit and fix cabin parts of different diameters. The axial limiting and fixing mechanism is installed on the radial limiting and fixing mechanism and is used to radially limit and fix the cabin parts. This realizes the rapid fixing of cabin parts to the support and the rapid installation of the support onto the worktable of the cleaning equipment, thereby enabling the cleaning equipment to drive the cabin parts to rotate and vibrate for secondary cleaning of the cabin parts.

[0017] (2) The present invention also includes a retainer, which is used to adjust the position of the limiting screw on the bracket and keep the limiting screw in contact with the outer surface of the cabin part, thereby realizing that the limiting screw keeps in contact with the outer surface of the cabin part when installing the pressure plate and tightening the fastening bolt, thereby enhancing the radial limiting and fixing of the limiting screw on the cabin part.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0027] Example 1

[0028] A specific embodiment of this utility model discloses a secondary powder cleaning fixture for additive manufacturing cabin parts, used to mount cabin parts 100 onto a powder cleaning device for secondary powder cleaning, such as... Figure 1As shown, the device includes a support 1, a radial limiting and fixing mechanism 2, and an axial limiting and fixing mechanism 3. The support 1 supports the cabin part 100 and can be fixedly connected to the worktable in the cleaning equipment. The radial limiting and fixing mechanism 2 is installed on the support 1 and can move on the support 1 to quickly radially limit and fix the cabin part 100 of different diameters, thereby preventing radial movement during cleaning of the cabin part 100. The axial limiting and fixing mechanism 3 is installed on the radial limiting and fixing mechanism 2 to quickly radially limit and fix the cabin part 100, thereby preventing axial movement during cleaning of the cabin part 100. Compared with the prior art, this embodiment quickly fixes the cabin part 100 to the support 1 through the radial limiting and fixing mechanism 2 and the axial limiting and fixing mechanism 3, and quickly installs it onto the worktable in the cleaning equipment through the support 1, thereby realizing the cleaning equipment driving the cabin part 100 to rotate and vibrate for secondary cleaning of the cabin part 100.

[0029] Preferably, such as Figure 2 As shown, the support 1 is provided with a sliding groove 11, and multiple sliding grooves 11 are provided, which are evenly arranged around the circumference.

[0030] Preferably, the radial limiting and fixing mechanism 2 includes a limiting screw, one end of which is disposed in the slide groove 11 and can slide in the slide groove 11, thereby making the limiting screw contact the outer surface of the cabin part 100; the other end of the limiting screw is connected to the axial limiting and fixing mechanism 3.

[0031] Preferably, multiple limiting screws are provided, and each of the multiple limiting screws can contact the outer surface of the cabin part 100, thereby realizing rapid radial limiting and fixing of cabin parts 100 with different diameters, and thus preventing radial movement during the cleaning of cabin parts 100.

[0032] Preferably, the axial limiting and fixing mechanism 3 includes a pressure plate 31 and a fastening bolt 32. The pressure plate 31 is inserted through the limiting screw and can contact the end face of the cabin part 100. The fastening bolt 32 is sleeved on the limiting screw and threadedly connected to the limiting screw. Tightening the fastening bolt 32 can make the pressure plate 31 fit firmly against the end face of the cabin part 100, thereby axially limiting and fixing the cabin part 100. It can also fix the limiting screw in the slide groove 11, so that the limiting screw keeps in contact with the outer surface of the cabin part 100, thereby radially limiting and fixing the cabin part 100.

[0033] In use, place the cabin part 100 on the support 1; adjust the position of the limiting screw in the slide groove 11 so that the limiting screw contacts the outer surface of the cabin part 100; put the pressure plate 31 on the limiting screw and make the pressure plate 31 contact the end face of the cabin part 100; install the fastening bolt 32 on the limiting screw and tighten the fastening bolt 32 to make the pressure plate 31 fit firmly against the end face of the cabin part 100, thereby axially limiting and fixing the cabin part 100, and also fixing the limiting screw in the slide groove 11, thereby radially limiting and fixing the cabin part 100; fix the tooling together with the cabin part 100 on the cleaning equipment; start the cleaning equipment to drive the cabin part 100 to rotate and vibrate, realizing the secondary cleaning of the cabin part 100.

[0034] Example 2

[0035] Example 2 is a further improvement based on Example 1, such as... Figure 3 As shown, the tooling also includes a retainer 4, which is used to adjust the position of the limiting screw in the slide groove 11 and keep the limiting screw in contact with the outer surface of the cabin part 100, thereby achieving that the limiting screw keeps in contact with the outer surface of the cabin part 100 when installing the pressure plate 31 and tightening the fastening bolt 32, thereby enhancing the radial limiting and fixing of the limiting screw on the cabin part 100.

[0036] Preferably, the retainer 4 includes a ring seat 41 and a retaining screw 42. The ring seat 41 is mounted on the support 1, and the retaining screw 42 is mounted on the ring seat 41 and can slide radially along the ring seat 41. The retaining screw 42 is arranged opposite to the limiting screw, so that by adjusting the position of the retaining screw 42 on the ring seat 41, the position of the limiting screw in the slide groove 11 can be adjusted, and the limiting screw is kept in contact with the outer surface of the cabin part 100. This ensures that the limiting screw is kept in contact with the outer surface of the cabin part 100 when the pressure plate 31 is installed and the fastening bolt 32 is tightened, thereby enhancing the radial limiting and fixing of the cabin part 100 by the limiting screw.

[0037] Preferably, the retainer 4 further includes a control bolt 43, which is mounted on the ring seat 41 and can rotate relative to the ring seat 41. The control bolt 43 is sleeved on the retaining screw 42 and threadedly connected to the retaining screw 42. Tightening the control bolt 43 can quickly and conveniently adjust the position of the retaining screw 42 on the ring seat 41, thereby quickly and conveniently adjusting the position of the limiting screw in the slide groove 11 and keeping the limiting screw in contact with the outer surface of the cabin part 100. This ensures that the limiting screw is in contact with the outer surface of the cabin part 100 when the pressure plate 31 is installed and the fastening bolt 32 is tightened, thereby enhancing the radial limiting and fixing of the limiting screw on the cabin part 100.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
