Description

Technical Field

[0001] The present invention relates to the technical field of industrial software platforms, and in particular, to a method, device, system, and medium for identifying thread hole features of a 3D lightweight model. Background Art

[0002] With the continuous development of the non-standard mechanical design industry, the selection and application of purchased parts in the manufacturing industry are becoming more and more widespread. At present, the mainstream method for selecting purchased parts in China is to search for appropriate component parameter information and 3D model files on some industrial software platforms such as CADENAS, 3DSource, and Big Engineer. Current mainstream industrial basic resource library software such as CADENAS and 3DSource platforms have the function of lightweight display of component models. The 3D model lightweight display is an entity that only retains the external shape structure features of the model. The 3D model lightweight display function can directly browse the model without downloading the model file and opening it through other modeling design software. In this way, compared with product annotation drawings and product physical drawings, it can more intuitively reflect the structural features of components and facilitate designers to quickly select models.

[0003] Restricted by technology, the current 3D model lightweight display has the following defects for thread hole features:

[0004] (1) The 3D lightweight model cannot identify and display the helix feature of the thread hole, generally showing as a through hole, which is not convenient for users to intuitively distinguish between through holes and thread holes;

[0005] (2) For the inner diameter of the thread hole in the 3D lightweight model, it generally shows as the minor diameter of the thread.

[0057] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of a method for identifying threaded hole features of a 3D lightweight model provided by an embodiment of the present invention.

[0058] A method for identifying threaded hole features of a 3D lightweight model according to an embodiment of the present invention is applied to a cloud server 1 and includes the following steps:

[0059] S10. Receive a 3D lightweight model to be identified uploaded by a networked device terminal 2 to the cloud server 1.

[0060] In this embodiment, the networked device terminal 2 is connected to the cloud server 1, and the user can connect to the cloud server 1 through the web interface page of the networked device terminal 2. It can be understood that the number of networked device terminals 2 is not limited, and each can upload its own 3D lightweight model to be identified to the cloud server 1.

[0061] S20. Identify the 3D lightweight model to identify the threaded holes in the 3D lightweight model.

[0062] In this embodiment, as Figure 4 shown, the cloud server 1 is deployed with a 3D lightweight model threaded hole identification software tool 11 for identifying the threaded holes of the 3D lightweight model to be identified, so as to solve the problem that the industrial software platform cannot directly identify the threaded hole features of the 3D lightweight model.

[0063] In a specific embodiment, the step S20 of identifying the 3D lightweight model to identify the threaded holes in the 3D lightweight model includes the following steps:

[0064] S21. Identify all entity depressions in the 3D lightweight model;

[0065] S22. Identify the cylindrical depressions among all the entity depressions;

[0066] S23. Measure the hole diameter of the cylindrical depression;

[0067] S24. Identify the threaded holes in the 3D lightweight model based on the hole diameter of the cylindrical depression.

[0068] In this embodiment, the threaded hole recognition software tool 11 first identifies all the solid depressions in the 3D lightweight model, then identifies the cylindrical depressions among all the solid depressions, measures the hole diameter of the cylindrical depressions, and finally identifies the threaded holes in the 3D lightweight model based on the hole diameter of the cylindrical depressions.

[0069] In a specific embodiment, the step S24 of identifying the threaded holes in the 3D lightweight model based on the hole diameter of the cylindrical depression includes the following steps:

[0070] S241. Based on the hole diameter of the cylindrical depression, determine whether the inner diameter of the hole of the cylindrical depression contains two or more decimal places and whether it conforms to the minor diameter data in the threaded hole diameter information database;

[0071] S242. If so, determine whether the cylindrical depression is a blind hole;

[0072] S243. If so, determine whether the bottom hole diameter of the blind hole is smaller than the end face hole diameter of the blind hole;

[0073] S244. If so, determine that the blind hole is a threaded hole.

[0074] In this embodiment, the threaded hole recognition software tool 11 first identifies the hole features of the 3D lightweight model entity, and then distinguishes whether it is a threaded hole based on the inner diameter data and whether there is a low hole.

[0075] Specifically, the threaded hole recognition software tool 11 determines whether the inner diameter of the hole of the cylindrical depression contains two or more decimal places based on the hole diameter of the cylindrical depression, and determines whether the inner diameter of the hole conforms to the minor diameter data in the threaded hole diameter information database. The threaded hole recognition software tool 11 can initially screen out the candidate holes that may be threaded holes by checking whether the inner diameter of the hole contains two or more decimal places. Because in practical applications, the inner diameters of ordinary light holes or other non-threaded holes are usually integers or one decimal place, while the inner diameter size of threaded holes may be more precise due to their close association with thread specifications and often have two or more decimal places. The threaded hole recognition software tool 11 then compares the inner diameter of the hole with the minor diameter data in the threaded hole diameter information database, and allows a deviation within 3%. This step can more accurately determine whether the hole meets the size standard of the threaded hole. Since different specifications of threaded holes have corresponding standard minor diameter sizes, by comparing with the threaded hole diameter information database, the holes that meet the size characteristics of the threaded holes can be effectively identified.

[0076] Among them, such as Figure 4As shown, the thread hole diameter information library module 12 in the cloud server 1 that conforms to national or international standards is configured with a thread hole diameter information library. The thread hole diameter information library may contain tabular information such as thread codes, nominal diameters, and minor diameters of threads, and its format is as shown in Figure 2 shown.

[0077] The thread hole recognition software tool 11 further determines whether the cylindrical depression is a blind hole. For a blind hole, if the bottom hole diameter (drilled hole diameter) is smaller than the end face hole diameter, the end face hole can be determined as a thread hole. This is based on the processing technology characteristics of thread holes. When machining blind hole threads, due to factors such as the taper of the tap, the end face hole diameter will be slightly larger than the bottom hole diameter, while other types of blind holes usually do not have this characteristic.

[0078] S30. Read the thread holes in the 3D lightweight model to obtain national standard thread hole information.

[0079] In this embodiment, the thread holes in the 3D lightweight model can be matched with the thread hole diameter information library one by one, and finally the number of thread holes and the national standard thread code information are output.

[0080] In a specific embodiment, the step S30 of reading the thread holes in the 3D lightweight model to obtain national standard thread hole information includes the following steps:

[0081] S31. Match the minor diameter data of the thread hole diameter information library based on the inner diameter of each thread hole to read the national standard thread code of each thread, and obtain the national standard thread codes and corresponding quantity information of all the thread holes.

[0082] In this embodiment, based on the inner diameter of the thread hole, match the minor diameter value of the thread in the thread hole diameter information library (within a deviation of 3%) to read the national standard thread code. After identifying all the thread hole information, output the national standard thread codes and corresponding quantity information of all the thread holes.

[0083] S40. Feed back the national standard thread hole information to the networked device terminal 2 so that the networked device terminal 2 can display the national standard thread hole information and display the rendered image of the thread holes in the 3D lightweight model.

[0084] In this embodiment, the national standard thread hole information is displayed in the web window of the networked device terminal 2, specifically sorted by hole diameter size, and the rendered image of the thread holes in the 3D lightweight model is displayed by the web window.

[0085] In a specific embodiment, the method further includes the following steps:

[0086] S50. Render the circumferential surfaces of threaded holes with different specifications into different colors through the hole circumferential surface rendering module 13 in the cloud server 1 to obtain the threaded hole rendering diagram of the 3D lightweight model;

[0087] S60. Feed back the threaded hole rendering diagram of the 3D lightweight model to the networked device terminal 2.

[0088] In this embodiment, the hole circumferential surface rendering module 13 deployed in the cloud server 1 is called (as Figure 4 shown) to assign different colors to the circumferential surfaces of threaded holes with different specifications, that is, to perform coloring, to obtain the threaded hole rendering diagram of the 3D lightweight model, and then feed back the threaded hole rendering diagram of the 3D lightweight model to the networked device terminal 2, and the color - quantity - thread code information and the threaded hole rendering diagram are displayed by the web window of the networked device terminal 2.

[0089] In this way, the threaded holes of the 3D lightweight model can be identified and special colors can be assigned, which is convenient for intuitively reflecting the positioning, connection, and locking feature structures of the model, and can also directly output the national standard specification codes of the threaded holes, facilitating the user to select bolt components.

[0090] In summary, a method for identifying the threaded hole features of a 3D lightweight model provided by an embodiment of the present invention identifies the 3D lightweight model through the cloud server 1 to identify the threaded holes in the 3D lightweight model, then reads the threaded holes in the 3D lightweight model to obtain the national standard threaded hole information, and finally feeds back the national standard threaded hole information to the networked device terminal 2 so that the networked device terminal 2 displays the national standard threaded hole information and shows the threaded hole rendering diagram of the 3D lightweight model. In this way, the problem that the current industrial software platform cannot directly identify the threaded hole features of the 3D lightweight model is solved. At the same time, the national standard threaded hole information and the threaded hole rendering diagram can also be displayed, which is convenient for intuitively reflecting the threaded hole feature structure and also convenient for the user to select bolt components.
