Select an example of a bolt that matches the size of the assembly base for assembly

The more standard parts involved in the reuse of the design process, the more complex the assembly relationship and the more complex the design of the product, which requires the designer to have good design experience. In general, the design process has certain rules, including the general design process and certain industry design knowledge. If it is packaged in the standard parts library management system, it can improve the design efficiency and avoid the errors in the design. . Rapid assembly is an important manifestation of the reuse of the design process: it can automatically retrieve the hole faces in the assembly base, calculate the dimensions of each hole face, and then assemble the standard parts with matching dimensions; you can select a subassembly of a standard part according to your needs. For example, bolts, washers and nuts.

Based on the above theory of knowledge reuse, the system uses UG as the supporting platform to develop the standard parts library management system by using C and C++ language, which realizes the automation of the standard design of foaming isolation belt in the design process. Design efficiency. Taking quick assembly as an example, the design steps are as follows: Drag the bolt from the navigation bar to one side of the base, and the system automatically performs the following work: 1 size matching: if dragging onto the plane, calculate the thickness of the assembly base; On the cylinder, the diameter and height of the cylinder are calculated, and then an example of a bolt matching the size of the assembly base is selected for assembly. 2 Assembly Constraint: If it is dragged onto the plane, the fitting constraint is automatically generated between the assembly and the bolt; if it is dragged to the cylinder surface, the coaxial constraint is automatically generated between the two.
