Digital Automatic Assembly Technology of Stubble-Cutting Equipment of No-Till Planter

Abstract

In the process of product design, automatic assembly technology can shorten the time spent on assembling all parts into a virtual assembly. In this paper, a digital automatic assembly technology based on coordinate system constraint was put forward. Appropriate coordinate systems which can ensure the correct location of part were built during the establishment of part model through the datum tool. The naming method of coordinate system was prescribed. All coordinate systems in every part of stubble-cutting equipment were established. The steps of realizing automatic assembly were explained in detail. The functions Pro/Toolkit provides were used to program. The operation results show that the technology can reduce repetitive work, improve design efficiency and provide a convenient tool for the design of stubble-cutting equipment of no-till planter.
