Research on innovation design of the DTH drill based on reverse engineering

This paper analyzes the theory of reverse engineering methods, combining with digital modeling technology and virtual prototype technology, a model of product innovation design is established and the evaluation index is introduced based on the theory of reverse engineering. The design defects of a certain imported down-the-hole drill(DTH drilling rig) is analyzed. According to the process of innovation design model, innovative design of the DTH drilling rig is done and the strength of the improved structure is verified. The improved 3D model of DTH drilling rig is built by Pro/E, and the kinematics simulation analysis about key components of the new products is carried out. There is no interference phenomenon in the simulation results analysis, which verifies the rationality of the model establishment.
