Description

Technical Field

[0001] The invention relates to the technical field of appearance inspection, and in particular to a device for assisting in inspecting the appearance of a selected area laser melted formed part. Background Art

[0002] Selective Laser Melting (SLM) technology is a type of additive manufacturing technology, which is widely used in aerospace, automotive, military and other industries. Compared with traditional processing methods, its biggest advantage is that it can quickly form workpieces with complex structures in one go. This advantage not only shortens the processing cost and cycle of complex parts themselves, but also makes it possible to manufacture workpieces that were previously impossible to manufacture.

[0003] The selective laser melting process requires a substrate on which the workpiece "grows". After the process is completed, the operator removes the substrate (along with the workpiece) and places it on a pallet truck. Workpieces formed by selective laser melting often have appearance problems such as bottom cracks, local holes, and local joints, which require manual inspection. In order to avoid missing the appearance problems of the workpiece, manual inspection currently requires long periods of bending and squatting when checking the appearance of the workpiece, which can easily cause fatigue and lead to the loss of many details.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, terms such as "up", "down", "left", and "right" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0035] In addition, the terms "first", "second", etc. are merely used to distinguish in description and have no special meanings.

[0036] See also Figures 1 to 4 As shown, this embodiment provides a device for assisting in inspecting the appearance of a selected area laser melted formed part, comprising a base 1, a fixed beam 2, a support rod 3 and a locking member 4, wherein:

[0037] The fixed beam 2 is arranged on the base 1, and a vertical slide groove 21 is provided on the fixed beam 2;

[0038] The support rod 3 passes through the vertical slide groove 21 and can be lifted and lowered along the vertical slide groove 21. The front end of the support rod 3 is used to suspend the base plate 5 loaded with the selected area laser melting formed part. The base plate 5 is provided with a positioning hole 51 for the support rod 3 to pass through.

[0039] The locking member 4 is detachably disposed on the fixed beam 2 , and is used to lock the support rod 3 in the vertical slide groove 21 , thereby fixing the base plate 5 at a set height.

[0040] Therefore, the substrate 5 and the selective laser melting part can be simply suspended and fixed to check the appearance of the selective laser melting part, which reduces the difficulty of manual operation and improves the detection efficiency and the reliability of the detection result.

[0041] Optionally, a side plate 22 is provided on the side of the fixed beam 2 , and a plurality of limiting holes 23 distributed at vertical intervals are opened on the side plate 22 , and the locking member 4 can be selectively inserted into one or more of the limiting holes 23 .

[0042] Thus, the locking member 4 is inserted into the limiting holes 23 at different heights, and the position of the locking member 4 is quickly selected and fixed, thereby determining the position of the substrate 5, ensuring that the substrate 5 remains stable during the inspection process, thereby achieving accurate appearance inspection of the selected laser melted formed part. In addition, the addition of the side plate 22 also increases the structural strength of the fixed beam 2, making it safer and more reliable during operation.

[0043] Furthermore, the locking member 4 includes a fork handle 41 and a fork ear 42 located at the front end of the fork handle 41 . The fork ear 42 passes through two adjacent limiting holes 23 , and the support rod 3 is clamped between the fork ears 42 .

[0044] Therefore, the design of the locking piece 4 is convenient for operating the switching position and ensures that the support rod 3 is stably fixed in the vertical slide groove 21, and the fork ear 42 can also limit the base plate 5 to prevent the base plate 5 from sliding out of the front end of the support rod 3, thereby ensuring safety during the inspection process.

[0045] Optionally, two fixed beams 2 are arranged side by side, the side plates 22 are respectively arranged on the opposite outer sides of the two fixed beams 2 , the base plate 5 is placed between the two side plates 22 , and the positioning holes 51 on the base plate 5 are located at both side edges of the base plate 5 .

[0046] Thus, the substrate 5 is placed on the fixed beam 2 more stably, ensuring that the substrate 5 is not easily deflected during the inspection process, and the structure is more reasonable and stable.

[0047] Optionally, a push-pull handle 31 is provided at the rear end of the support rod 3 to facilitate manual operation of raising and lowering the support rod 3 , that is, to adjust the position height of the substrate 5 .

[0048] Optionally, the fixed beam 2 is a split structure, the fixed beam 2 includes an upper half and a lower half, the lower half is upright fixed on the base 1, the upper half and the top of the lower half are connected by a rotating shaft 24, and the upper half can be alternately moved to a vertical position spliced ​​with the lower half and a horizontal position perpendicular to the lower half.

[0049] Thus, by rotating the upper part around the rotating shaft 24 to a horizontal position, the substrate 5 and the selective laser melting part can be placed horizontally together to facilitate inspection from different angles. This split structure design makes the use of the entire device more flexible and further enhances the convenience and accuracy of inspection. In addition, in some cases, when the upper part is in a horizontal position, the substrate 5 and the selective laser melting part are easier to remove, thereby improving work efficiency.

[0050] Further, a support arm 25 is provided on one of the upper half and the lower half, and the support arm 25 is used to abut against the other of the upper half and the lower half when the upper half is in a horizontal position. In this embodiment, the support arm 25 is provided on the upper half as an example.

[0051] Thus, the support arm 25 improves the support strength of the upper part when it is in a horizontal position, thereby ensuring the stability and safety of the entire device.

[0052] Optionally, a fixing plate 26 is disposed on one of the upper and lower halves, and the fixing plate 26 is used to be fixedly connected to the other of the upper and lower halves when the upper half is in a vertical position. In this embodiment, the fixing plate 26 is disposed on the lower half as an example.

[0053] Therefore, the fixing plate 26 improves the structural stability of the upper part when it is in a vertical position, thereby avoiding abnormal turning over.

[0054] Optionally, a limiting cavity 27 is provided in the vertical slide groove 21, and a convex block 32 is provided on the support rod 3 to move in the limiting cavity 27. Thus, the support rod 3 is limited from coming out of the vertical slide groove 21 through the cooperation between the convex block 32 and the limiting cavity 27, so as to avoid the front end of the support rod 3 from being unbalanced after being subjected to force, thereby ensuring the accurate lifting and lowering movement of the support rod 3 and ensuring the stability and safety of the substrate 5 and the selected laser melted formed part during the movement.

[0055] Optionally, a roller 11 is provided at the bottom of the base 1 .

[0056] Therefore, the mobility of the entire device is improved by the roller 11, so as to dock the substrate 5 and transfer the selected laser-melted parts. The roller 11 can be locked or moved freely, meeting the use requirements.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
