Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a horizontal fixed platform for monitoring defects in SLM-molded products. Background Technology

[0002] SLM (Surface Mount Metal) forming is an advanced metal 3D printing technology that uses high-energy lasers to melt metal powder layer by layer to build complex three-dimensional metal parts. It has wide applications in aerospace, medical, and automotive manufacturing. However, defects such as porosity, cracks, and incomplete fusion can occur during the SLM forming process, affecting the mechanical properties and durability of the parts. Therefore, defect detection is crucial. Common detection methods include X-ray inspection, ultrasonic testing, and machine vision-based surface defect analysis. Furthermore, when monitoring defects in SLM-formed products, it is necessary to fix the product in place using a horizontal platform to prevent accidental displacement or deflection during defect monitoring, which could affect the effectiveness and accuracy of the monitoring.

[0003] Existing horizontal fixing platforms for SLM forming product defect monitoring typically use clamping to fix the product. However, SLM forming products often have diverse and irregular shapes, making it difficult for conventional clamping methods to effectively and stably fix them. Furthermore, the placement surface of existing horizontal fixing platforms cannot be effectively adjusted to adapt to the irregular shape of SLM forming products, making it difficult to keep irregular SLM forming products stable during placement and easily affecting the defect monitoring results. Consequently, existing horizontal fixing platforms have poor versatility.

[0004] Based on the above, this utility model proposes a highly versatile horizontal fixing platform for defect monitoring of SLM molded products. Utility Model Content

[0005] To overcome the shortcomings of existing horizontal fixing platforms for SLM molding product defect monitoring, which use conventional clamping methods to effectively and stably fix SLM molding products of various and irregular shapes, and whose placement surfaces cannot be effectively adapted to the irregular shapes of SLM molding products, making it difficult to keep irregular SLM molding products stable during placement and easily affecting the defect monitoring results, thus resulting in poor versatility of existing horizontal fixing platforms, this utility model provides a highly versatile horizontal fixing platform for SLM molding product defect monitoring.

[0006] The technical implementation scheme of this utility model is as follows: A horizontal fixed platform for defect monitoring of SLM formed products includes a base frame, an isolation cover, a movable platform, a telescopic assembly, a mounting plate, control valves, limit rods, iron blocks, and an electromagnetic frame. The telescopic assembly is mounted on the base frame, and the movable platform is mounted on the telescopic assembly.

An electromagnetic frame is fixedly connected to the mounting plate. The electromagnetic frame and the iron blocks are magnetically attracted to each other. The electromagnetic frame is electrically connected to the control valves.

[0007] Optionally, the mounting plate is made of iron and has evenly distributed circular holes.

[0008] Optionally, it also includes a card holder and a strong magnetic block. The mounting plate is slidably connected to the card holder, which contacts and engages with the limit rod. The card holder is fixedly connected to a pair of strong magnetic blocks, which magnetically engage with the mounting plate.

[0009] Optionally, the card holder is fixed with a handle.

[0010] Optionally, it also includes a level and a fine-tuning rod, with a pair of levels fixed to the moving platform and a pair of fine-tuning rods threadedly connected to the base frame.

[0011] Optionally, it also includes a protective cover, a folding frame, and rotating rods. A pair of rotating rods are fixedly connected to the moving platform, and a folding frame is rotatably connected between the pairs of rotating rods. The protective cover is fixedly connected to the folding frame.

Detailed Implementation

[0022] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] Example 1

[0024] A horizontal fixed platform for defect monitoring of SLM molded products, such as Figures 1-5 As shown, the system includes a base frame 1, an isolation cover 11, a moving platform 13, a telescopic assembly 14, a mounting plate 15, a control valve 16, a limit rod 17, an iron block 19, and an electromagnetic frame 110. The telescopic assembly 14 is mounted on the top of the base frame 1, and the moving platform 13 is mounted on the top of the telescopic assembly 14. The isolation cover 11 is fixedly connected between the moving platform 13 and the base frame 1. The mounting plate 15 is rotatably connected to the top of the moving platform 13. The control valve 16 is fixedly connected to both the left and right sides of the top of the moving platform 13. The limit rods 17 are evenly distributed and slidably connected inside the mounting plate 15. The iron block 19 is fixedly connected to the bottom of the limit rod 17. The electromagnetic frame 110 is fixedly connected to the middle of the mounting plate 15. The electromagnetic frame 110 and the iron block 19 are magnetically attracted to each other. The electromagnetic frame 110 is electrically connected to the control valve 16.

[0025] like Figures 2-5As shown, the mounting plate 15 is made of iron and has evenly distributed round holes on its top.

[0026] like Figure 4 and Figure 6 As shown, it also includes a card holder 18 and a strong magnetic block 1801. The card holder 18 is slidably connected inside the mounting plate 15. The card holder 18 is in contact with the limiting rod 17. The front and rear parts of the left and right sides of the card holder 18 are fixedly connected with strong magnetic blocks 1801. The strong magnetic blocks 1801 are magnetically attracted to the mounting plate 15.

[0027] like Figure 4 and Figure 6 As shown, a handle is fixed to the right side of the card holder 18.

[0028] like Figure 1 and Figure 2 As shown, it also includes a level 12 and a fine-tuning rod 1201. The level 12 is fixedly connected to the left front side and the right rear side of the moving platform 13, and the fine-tuning rod 1201 is threadedly connected to the left and right sides of the front and rear sides of the base frame 1.

[0029] When workers need to monitor defects in SLM molded products, they can first adjust the moving platform 13 and mounting plate 15 to a suitable height using the telescopic assembly 14. The isolation cover 11 will then adapt by extending or shortening under the action of the moving platform 13. Then, the level 12 is used to determine if the moving platform 13 and mounting plate 15 are level. If not, the tilt angle of the moving platform 13 and mounting plate 15 can be adjusted by turning the fine-tuning rod 1201 until they are level. Next, the SLM-molded product can be placed on top of the mounting plate 15. Then, the electromagnetic frame 110 is activated via the control valve 16. The electromagnetic frame 110 then generates magnetism and uses magnetic force to move the evenly distributed iron blocks 19 and limiting rods 17 upward. The iron blocks 19 and limiting rods 17 located at the bottom of the SLM-molded product will move upward under the action of the electromagnetic frame 110 until the limiting rods 17 abut against the bottom of the SLM-molded product and support it. The other iron blocks 19 and limiting rods 17 will move upward under the action of the electromagnetic frame 110 until the iron blocks 19 are attracted to the electromagnetic frame 110. The components are fixed together, with the limiting rod 17 located at the edge of the SLM-molded product also limiting the product. Then, the rubber holder 18 can be moved to the left, causing the strong magnetic block 1801 to move to the left as well, until the holder 18 contacts the limiting rod 17. At this point, the right end of the strong magnetic block 1801 will separate from the mounting plate 15, while the left end of the strong magnetic block 1801 will be attracted and fixed to the mounting plate 15 under the action of magnetic force. The holder 18 will also press against the limiting rod 17 under the action of the strong magnetic block 1801, thereby improving the stability of the limiting rod 17. This allows the product to be molded according to the SLM molding process. The product's shape is adaptively adjusted, and the product is effectively and stably supported and fixed, thereby preventing the SLM molded product from shifting or deflecting during defect monitoring and affecting the defect monitoring results. After fixing, the defects of the SLM molded product can be monitored by external equipment. After the monitoring is completed, the card holder 18 and the strong magnetic block 1801 are moved to the right to reset, and the electromagnetic frame 110 is closed by the control valve 16. At this time, the iron block 19 is no longer affected by the magnetic force and will drive the limit rod 17 to move downward to reset under the action of gravity. Finally, the SLM molded product can be removed from the mounting plate 15.

[0030] Example 2

[0031] Based on Example 1, such as Figure 1 and Figure 7 As shown, it also includes a protective cover 2, a folding frame 21 and a rotating rod 22. The rotating rod 22 is fixedly connected to both the front and rear sides of the middle of the moving platform 13. The folding frame 21 is rotatably connected between the front and rear rotating rods 22. The protective cover 2 is fixedly connected to the middle of the folding frame 21.

[0032] When monitoring defects in SLM molded products using external equipment, workers can also rotate both ends of the folding frame 21 downwards and unfold them to contact the left and right sides of the moving platform 13 respectively. This allows the protective cover 2 to be unfolded and provide a wrap-around protection for the SLM molded product, thereby preventing dust and other impurities from the external environment from adhering to the surface of the SLM molded product and affecting the defect monitoring results. After monitoring is completed, either end of the folding frame 21 can be rotated in the opposite direction and the folding frame 21 can be folded and stored.

[0033] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
