Abstract


In cutting large diameter cylindrical housing eccentric hole and variable groove angle has been the shipbuilding industry a problem, although there are already devices can complete the cut, but there are some limitations , therefore , the subject will study is based on series-parallel structure of the new cutting mechanism , in order to meet the changing needs of the cutting body . Based on cutting holes and beveling of the basic functional requirements , the use of series and parallel mechanism with five degrees of freedom of the technical design of the new cutting mechanism . Finished cutting machine mechanical structure design ; portion of the parallel institutions carried out a detailed kinematic analysis of the agency's position is obtained , the speed of inverse solution and institutional Jacobian matrix to determine the 3 DOF planar parallel mechanism workspace geometric method given point belongs to the workspace Criterion ; analyzes the impact of the precision cutting machine movement factor ; by using Pro / E and RecurDyn software for cutting machine kinematics simulation to verify the reasonableness of the design agency and good dynamic characteristics. This article is designed cutting mechanism , the use of a combination of series and parallel structure, the cutting machine can accomplish in the working space within the arbitrary curve machining .
