| Abstract: |
| In order to increase design efficiency and reduce assemble work of disc coulter, the key technologies of parametric design were analyzed. The technology of automatic assembling and batch automatic assembling based on constraint coordinate system was presented, and the method of building constraint coordinate system and the steps of realizing automatic assembling were also investigated. The VC ++6.0 software and the underlying functions provided by Pro/toolkit were used to develop the parametric design and automatic assembling platform for disc coulter. The authentication results by real cases showed that the programming was easy by the parametric design method that integrated the model and the program. Parts can be designed by interface operation in the environment of Pro/E. The automatic assembling technology based on constraint coordinate system requires no any matrix operation. Every part only needs to establish a constraint coordinate system for the reference part. User can accomplish assembly by selecting the corresponding coordinate systems for the assemble part and the reference part. The batch automatic assembling technology is applicable to two cases that the assembly constraint coordinate systems are on a part or on many same parts. The assembly of multiple bolts or nuts can be automatically finished by one operation. The parametric design and automatic assembling technology may be applied toward a series of design for disc coulter and are beneficial in decreasing the repetitive assemble work. |
