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...
