[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0050] At present, major OEMs use virtual assembly technology to complete the assembly process verification of parts. That is, in a virtual environment, the assembly process of environmental parts 300 is simulated, and process evaluation and improvement work are carried out.

[0051] The assembly processability of components mainly includes dimensions such as assembly path, tool space, assembly human-machine interface, and assembly cycle time. Among these, tool space verification is an important and necessary verification task. Due to the variety of types and models of connectors, tool space verification is relatively cumbersome and time-consuming. The basic idea of ​​traditional tool space verification is to select tools and components based on the structural characteristics and technical parameters of the connectors, and then use virtual matching technology to complete the virtual assembly between tools, components, and connectors, thereby judging the tool space compliance.

[0052] Specifically, such as Figure 1 As shown, traditional virtual verification involves matching assembly tools and components with parts and judging the conformity of the assembly process based on the spatial relationship after matching. Specifically, taking the spatial verification process of bolt assembly tools as an example: First, the technical parameters, assembly requirements, and surrounding space characteristics of the connector to be verified are clarified; then, assembly tools and components such as sleeves and connecting rods are selected according to the technical parameters of the connector; finally, the assembly tools, components, and connectors are matched, and the processability judgment is completed based on the virtual assembly position relationship.

[0053] The above methods involve numerous matching steps, which is time-consuming. When the types of connectors are not uniform, the matching work in the third step becomes even more cumbersome. Furthermore, in actual verification processes, the tool data is often point clouds, lacking regular geometric structures such as points, lines, and surfaces. The tool and connectors can only use imprecise matching, making the verification process extremely time-consuming and difficult to perform rapid, batch-based process verification.

[0054] The inventors of this invention have improved the existing methods to address the problems of the above-mentioned technologies and proposed a fastener assembly space verification method.

[0055] The fastener assembly space verification method according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] The fastener assembly space verification method according to the embodiments of the invention includes the following steps:

[0057] S1. Obtain the technical parameters of connector 10 and serialize connector 10 according to the technical parameters;

[0058] S2. Select an assembly tool 20 that matches the connector 10. The assembly tool 20 and the connector 10 are integrated into a virtual assembly unit 100.

[0059] S3. Based on the connector 10 to be verified, select the virtual assembly unit 100, match the connector 10 in the virtual assembly unit 100 with the connector to be verified, and determine whether it meets the assembly requirements of the assembly space.

[0060] In other words, such as Figure 2 As shown, this fastener assembly space verification method differs from the traditional virtual verification method. Before verifying the assembly space of connector 10, connector 10 is first divided into different series, such as... Figures 3 to 5 As shown. The assembly tool 20 can be integrated with different series of connectors 10 to form different virtual assembly units 100, such as... Figure 6 and Figure 7 As shown. During verification, only the virtual assembly unit 100 needs to be selected based on the connector 10, and its internal connector 10 needs to be matched with the connector to be verified. Compared to traditional verification methods, this method simplifies the selection process, reduces the number of tool matching operations, and improves verification efficiency. Furthermore, this fastener assembly space verification method is relatively simple and easy to program. Through secondary program development, it can be integrated with existing commercial CAD software.

[0061] Therefore, the fastener assembly space verification method according to the embodiments of the present invention, by serializing the connectors 10 and integrating the connectors 10 and the assembly tools 20 into a virtual assembly unit 100, not only simplifies tool selection and improves tool space verification efficiency, but also facilitates software integration.

[0062] According to one embodiment of the present invention, in step S1, the connector 10 is a bolt, and the connector 10 may also be a nut or other structure depending on the assembly requirements.

[0063] Preferably, in step S1, the technical parameters are the thread diameter and the length of the bolt.

[0064] Furthermore, in step S1, bolts with the same thread diameter belong to a series (e.g., Figure 3 and Figure 4 As shown), bolts with the same thread diameter but different lengths are grouped into a series, making it easier to assemble them with the same assembly tool 20 into different virtual assembly units 100 (such as...). Figure 6 This saves assembly time.

[0065] According to an embodiment of the present invention, in step S2, as Figure 7 As shown, the assembly tool 20 includes a connecting rod 21, a power component 22, and a sleeve 23.

[0066] Specifically, different assembly tools 20 are selected according to different connectors 10. One end of the connecting rod 21 is connected to the connector 10, and the power component 22 is connected to the other end of the connecting rod 21 to drive the connector 10 to rotate through the connecting rod 21. The sleeve 23 is fitted at the connection between the connecting rod 21 and the connector 10 to fix the connecting rod 21 and the connector 10.

[0067] In summary, the fastener assembly space verification method according to the embodiments of the present invention, by serializing the connectors 10 and integrating the connectors 10 and the assembly tools 20 into a virtual assembly unit 100, not only simplifies tool selection and improves tool space verification efficiency, but also facilitates software integration.

[0068] According to a second aspect of the present invention, a fastener assembly space verification device 200 includes a data acquisition module 210, an assembly module 220, and a verification module 230.

[0069] Specifically, such as Figure 8 As shown, the data acquisition module 210 acquires the technical parameters of the connector 10 and serializes the connector 10 according to the technical parameters. The assembly module 220 selects the assembly tool 20 that matches the connector 10. The assembly tool 20 and the connector 10 are integrated into a virtual assembly unit 100. The verification module 230 selects the virtual assembly unit 100 according to the connector 10 to be verified, matches the connector 10 in the virtual assembly unit 100 with the connector 10 to be verified, and determines whether it meets the assembly requirements of the assembly space.

[0070] In one embodiment of the present invention, the connector 10 is a bolt, but the connector 10 may also be a nut or other structure depending on the assembly requirements.

[0071] Preferably, the assembly tool 20 includes a connecting rod 21, a power component 22, and a sleeve 23 (collectively referred to as an assembly).

[0072] Specifically, different assembly tools 20 are selected according to different connectors 10. One end of the connecting rod 21 is connected to the connector 10, and the power component 22 is connected to the other end of the connecting rod 21 to drive the connector 10 to rotate through the connecting rod 21. The sleeve 23 is fitted at the connection between the connecting rod 21 and the connector 10 to fix the connecting rod 21 and the connector 10.

[0073] According to the fastener assembly space verification device of the present invention, by serializing the connectors 10 and integrating the connectors 10 and the assembly tools 20 into a virtual assembly unit 100, it not only simplifies tool selection and improves tool space verification efficiency, but also facilitates software integration.
