Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing, and in particular to a structure for quickly positioning a 3D printed part. Background Art

[0002] During the molding process of 3D printed parts, it is difficult to determine the processing datum for complex 3D printed part structures. Usually, the positioning datum of simple 3D printed parts can be determined by the relative position relationship between the substrate and the part. Or, if the 3D printed part has right-angled edges, the processing datum can be determined by the right-angled edges, or by marking. However, complex 3D printed parts, 3D printed parts without right-angled edges, will have no corresponding datum after printing is completed and the part support is removed. At this time, 3D scanning is needed to determine the positioning datum. However, determining the positioning datum through 3D scanning consumes a lot of time, and the processing cost will also be greatly increased. Therefore, in order to save costs and shorten the time to determine the positioning datum on the machine tool, a quick positioning datum structure can be printed directly on the 3D printed part. Summary of the Invention

[0003] The purpose of the present invention is to provide a structure for quickly positioning a 3D printed part, which has the advantage of rapid positioning and solves the problem that many 3D printed part structures do not take the processing part into consideration, thereby increasing the difficulty of the part's numerical control positioning process. Determining the positioning reference through three-dimensional scanning consumes a lot of time and greatly increases the processing cost.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a structure for quickly positioning a 3D printed part, comprising a positioning plate, part one, part two and part three, the outer ring of the positioning plate is surrounded by a slide groove, the front and rear sides of the top of the positioning plate are provided with through holes, the left and right sides of the inner cavity of the slide groove are slidably connected with a slider, the outer side of the slider is connected with a positioning reference block, the number of the reference reference blocks is six and is evenly distributed at the bottom of the positioning plate, the top of the slider is fixedly connected with a limiting block, the top of the limit block passes through the through hole and is slidably connected to its inner wall, the bottom of the positioning plate is fixedly connected with a reference reference block, the reference reference hole is provided on the reference reference block, the positioning reference hole is provided on the positioning reference block, the positioning reference block is fixed on the left and right sides of part one, the positioning plate is fixedly sleeved at the middle end of the outer surface of part two, the top of the outer surface of part three is fixedly sleeved with a part plate, and the positioning reference holes are opened at the front and rear sides of the top of the part plate.

[0005] Preferably, the first part is a special-shaped part.

[0006] Preferably, the second part is a thin-walled part, the outer surface of the second part is provided with reinforcing ribs, and the positioning plate is fixedly sleeved on the reinforcing ribs.

[0007] Preferably, the third part is a characteristic part.

[0008] Preferably, the method for using the structure of a 3D printed part rapid positioning benchmark comprises the following steps:

[0009] A: When designing 3D printed parts, the processing datum is also taken into consideration. It only requires adding two process blocks and process holes at appropriate locations on the part. The shape of the process block needs to be designed based on factors such as part size, part structure, and the processing location of the part.

[0010] B: Design the size of the process block according to the size of the part. Generally, for parts with a length and width of more than 1 meter, the process block can be designed as a rectangular process block of 100mm×100mm×40mm. For parts with a length and width between 300mm and 1 meter, it can be designed as a rectangular process block of 50mm×50mm×20mm. For parts less than 300mm, it can be designed as a rectangular process block of 25mm×25mm×10mm.

[0011] C: Design the position of the process block according to the structure of the part. If the structure of the part is good and stable, the process blocks can be designed on both sides of the part. If the structure of the part is weak, the process blocks need to be designed near the reinforcement ribs. 3. If it is not possible to add process blocks on both sides of the part, you can also find a breakthrough inside the part structure and design process holes to achieve rapid positioning.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention has the advantage of rapid positioning through the coordinated use of a positioning plate, a positioning reference block, part one, part two, part three, a positioning reference hole, a part plate, a through hole, a reference hole, a reference block, a limit block, a slide groove and a slider, and solves the problem that many 3D printed parts have structures that do not take the processing part into consideration, thereby increasing the difficulty of the parts in the process of CNC positioning, and that determining the positioning reference through three-dimensional scanning consumes a lot of time and greatly increases the processing cost.

[0014] 2. The present invention can achieve the purpose of rapid positioning on the machine tool by printing the reference block together with the part during the 3D printing process, thereby improving the processing utilization rate of the machine tool. The structure of the rapid positioning reference can be used to make processing on the CNC machine tool more convenient and faster. The rapid positioning reference of the 3D printed parts can effectively shorten the part alignment time. Using this structure, even if the part does not have right-angled edges, it can be quickly positioned, which improves the positioning accuracy and makes processing more accurate. It saves the time for complex parts to determine the reference by three-dimensional scanning, thereby reducing processing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A method for using a structure for quickly positioning a datum for a 3D printed part comprises the following steps:

[0030] A: When designing 3D printed parts, the processing datum is also taken into consideration. It only requires adding two process blocks and process holes at appropriate locations on the part. The shape of the process block needs to be designed based on factors such as part size, part structure, and the processing location of the part.

[0031] B: Design the size of the process block according to the size of the part. Generally, for parts with a length and width of more than 1 meter, the process block can be designed as a rectangular process block of 100mm×100mm×40mm. For parts with a length and width between 300mm and 1 meter, it can be designed as a rectangular process block of 50mm×50mm×20mm. For parts less than 300mm, it can be designed as a rectangular process block of 25mm×25mm×10mm.

[0032] C: Design the position of the process block according to the structure of the part. If the structure of the part is very good and the stability is strong, the process blocks can be designed on both sides of the part; if the structure of the part is weak, the position of the process block needs to be designed near the reinforcement rib. Third, if it is not possible to add process blocks on both sides of the part, you can also find a breakthrough inside the part structure and design process holes to achieve the effect of rapid positioning.
