Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a 3D printer tooling device with a Delta structure. Background Art

[0002] 3D printing technology, also known as additive manufacturing, is a process of converting digital designs into physical objects. This process builds three-dimensional models by stacking materials layer by layer. It can be used for prototyping, product development, small-batch production, and in some cases, direct manufacturing of final products. With the development of 3D printing technology, more and more 3D printers based on 3D printing technology are entering the market. Among them, 3D printer guide rails are an important component of the 3D printer motion control system, which is used to guide the moving parts of the printer to move smoothly and accurately along a predetermined path. The guide rail system ensures that the nozzle or print bed can be accurately positioned during the 3D printing process, which is crucial to printing quality and accuracy.

[0003] However, if the guide rails of a 3D printer are not correctly aligned during installation, the moving parts will deviate from the predetermined path, affecting the printing accuracy. Therefore, it is particularly important to ensure that the parallelism and perpendicularity between the guide rails meet the requirements when installing the guide rails. To this end, we propose a 3D printer tooling device with a Delta structure. Utility Model Content

[0004] To solve the above technical problems, the present invention provides a 3D printer tooling device with a Delta structure, comprising:

[0005] Guide rails, wherein N guide rails are vertically provided;

[0006] The main body of the inspection tool can be installed between N vertical guide rails in a liftable manner;

[0007] Among them, the main body of the detection tooling includes a base plate, a pitch circle fixing seat is installed in the middle of the upper end surface of the base plate, and M fixing brackets are provided in a circular array on the periphery of the pitch circle fixing seat. A micrometer or a dial indicator can be detachably installed on the fixing bracket, and a guide support can be telescopically installed on the side of each fixing bracket facing away from the pitch circle fixing seat.

[0008] In some embodiments, N≥3, and M=N.

[0009] In some embodiments, a slide is fixed to the bottom end of the guide support, a slide rail is connected to the bottom end of the fixed bracket facing the guide support, and the slide is slidably fitted on the slide rail.

[0010] In some embodiments, the fixing bracket is provided with a through hole for the end of the micrometer or dial indicator to pass through.

[0011] In some embodiments, the top end of the fixing bracket is screwed into a locking screw for locking a micrometer or a dial indicator, and the locking screw is opposite to the through hole.

[0012] In some embodiments, the front side of the fixing bracket is convex to form a ledge, and the lower end surface height of the ledge is higher than the upper end surface height of the pitch circle fixing seat.

[0013] In some embodiments, a level is embedded in the middle of the upper end surface of the pitch circle fixing seat.

[0014] The utility model has at least the following beneficial effects:

[0015] Set up the inspection tooling body to assist in installing the guide rails of the 3D printer. During actual use, fix the micrometer on the fixed bracket, first measure the distance required for installation, and then lock it with the locking screws to ensure that the values ​​in the three directions are consistent. Then slide the tooling downward to lock the screws that fix the guide rails. During the process of fixing the guide rails, the distance of the tooling can be fine-tuned. After installation, replace the micrometer with a dial indicator. After the level is kept horizontal, slide the inspection tooling body up and down to observe the vertical jump of the dial indicator to detect whether the guide rails are installed vertically and parallel, so that multiple guide rails can be installed quickly and accurately to avoid skew.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-Figure 3 The utility model provides a technical solution: a Delta-structured 3D printer tooling device, comprising a detection tooling body 2 and a guide rail 4, wherein the guide rail 4 is vertically provided with N pieces, and the detection tooling body 2 can be lifted and installed between the N vertical guide rails 4 to be installed, N ≥ 3, wherein the detection tooling body 2 comprises a base plate 21, a dividing circle fixing seat 22 is installed at the middle of the upper end surface of the base plate 21, and a level 24 is embedded in the middle of the upper end surface of the dividing circle fixing seat 22, the level 24 is a device for measuring horizontal or vertical surfaces, which is an existing device, and the specific working principle is not repeated here, and the periphery of the dividing circle fixing seat 22 is provided with M fixed brackets 28 in a circular array, M = N, and a dial indicator 1 or a micrometer 3 is detachably installed on the fixed bracket 28, and a guide support 23 is telescopically installed on the side of each fixed bracket 28 facing away from the dividing circle fixing seat 22.

[0025] A slide 26 is fixed to the bottom end of the guide support 23, and a slide rail 27 is connected to the bottom end of the fixed bracket 28 facing the guide support 23. The slide 26 slidably fits on the slide rail 27. By sliding the slide 26 on the slide rail 27, the guide support 23 can be moved outward to adjust the distance during installation.

[0026] See Figure 3 As shown, the front side of the fixed bracket 28 bulges outward to form a ledge 281, and the lower end surface height of the ledge 281 is higher than the upper end surface height of the pitch circle fixing seat 22. The ledge 281 is used to place the dial indicator 1 or micrometer 3, and plays the role of supporting the dial indicator 1 or micrometer 3. A through hole 29 for the end of the dial indicator 1 or micrometer 3 to pass through is provided on the fixed bracket 28. A locking screw 25 for locking the dial indicator 1 or micrometer 3 is screwed into the top of the fixed bracket 28, and the locking screw 25 is opposite to the through hole 29. When installing the dial indicator 1 or micrometer 3, one end of the dial indicator 1 or micrometer 3 is passed through the through hole 29, and then the locking screw 25 can be used to tighten the installed dial indicator 1 or micrometer 3 to ensure stability.

[0027] In the above preferred embodiment, M=N=3. In this case, the 3D printer to be installed has three guide rails, and three fixed brackets 28 and guide supports 23 are synchronously provided. Each guide support 23 corresponds to a vertical guide rail, and three dial indicators 1 and micrometers 3 also need to be provided accordingly.

[0028] The specific usage process is as follows: when installing the equipment guide rail, the guide support 23 is fixed to the slide 26 of the slide rail 27, and the dial indicator 1 is fixed on the fixed bracket 28. The distance required for installation is measured and fixed with the locking screw 25 to ensure that the values ​​in the three directions are consistent. Then slide the tooling downward to lock the screws that fix the guide rails. During the process of fixing the guide rails, the distance of the tooling can be fine-tuned to ensure that the three guide rails are vertically parallel. After the installation is completed, the dial indicator 1 is replaced with the micrometer 3. After the level 24 is kept horizontal, slide the inspection tooling body 2 up and down to observe the vertical jump of the micrometer 3 to detect whether the guide rails are installed vertically and parallel.

The specific usage process thereafter is the same as that of the first embodiment and will not be repeated here.

[0032] In addition, M and N can also be 5 or other values, which can be determined according to the number of guide rails of the 3D printer equipment to ensure that multiple guide rails are installed vertically and parallel.
