Embodiment 1

[0032] Embodiment 1: A method for realizing a typical assembly process of a valve, including the following steps.

[0033] (1) Create a new process file in 3DCAPP-A, and import a set of 3D CAD model files of the valve.

[0034] (2) It is observed that there are 6 screw holes on the flange in the model, and 6 studs and nuts are installed respectively. For the convenience of description, they are respectively referred to as nut A, nut B, nut C, nut D, nut E, and nut F in a clockwise direction along the flange.

[0035] (3) Introduce the wrench assembly to define the disassembly activity for nut A.

[0036] (4) Set the nut to rotate counterclockwise, the direction is in the direction of the Y axis, and the number of rotations is 10. Position the wrench onto the nut, set the wrench to rotate 60 degrees and reciprocate 3 times. Then hide the wrench and set the nut to move 20 units in a straight line on the Y axis. Finally, a label is defined for the movement of dismounting the ...

Embodiment 2

[0046] Embodiment 2: A method for realizing a typical assembly process of a piston and a piston ring, including the following steps.

[0047] (1) Open a 3D model file containing piston and piston ring in 3DCAPP-A.

[0048] (2) Observe that there are 3 piston rings on the piston. For the convenience of description, they are called piston ring A, piston ring B and piston ring C respectively along the direction from the top of the piston to the bottom.

[0049] (3) Define the assembly motion for piston ring A first.

[0050] (4) Set the piston ring to rotate clockwise, the number of turns is 0.3, and the pitch is 0.

[0051] (5) Set the deformation activity and stretch the piston ring radially by 5 units.

[0052] (6) Set the piston ring to move 20 units linearly from the bottom to the top of the piston, and withdraw the ring from the ring groove.

[0053] (7) Repeat steps 4 to 6 to set the assembly movement for piston ring B and piston ring A in turn.

[0054] (8) After all t...

Abstract

The invention relates to a method and device for realizing a typical process in three-dimensional assembly simulation. The method includes: making a set of typical process 3D simulation process, saving it to a classification directory of the typical process library; opening the typical process library, entering a sub-category of the typical process library, and selecting a typical process under the sub-category; specifying the current scene The corresponding relationship between the parts in and the parts in the typical process, and the typical process is applied to the current scene. The device includes a typical process definition module, a typical process library module, and a typical process application module. The invention can more quickly and easily realize the reuse of process knowledge, and at the same time, when defining a typical process, it also accumulates the internal process knowledge of the enterprise.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional assembly simulation informatization, and in particular relates to a method and device for realizing a typical process in three-dimensional assembly simulation. Background technique [0002] In the existing 3D assembly simulation system, for each process preparation task, the components required in the process need to be manually assigned; tools and fixtures need to be manually imported; related simulation motion processes need to be manually defined; The instructions, diagrams, labels, process attributes, etc. need to be manually input; all details need to be defined by the user from scratch, regardless of whether the relevant simulation has been defined or not. [0003] Each process specification contains hundreds of specific process steps, and it is often very cumbersome to define from scratch, which is not only time-consuming and labor-intensive, but also error-prone. Process knowled...
