Description
Summary:Unified spindle nodes constructions of machining centres for drilling-milling and boring types are considered in this paper. 3D modelling of the main components for the spindle units on the rolling bearings is performed, including the construction of complex assemblies, kinematic schemes for shaping the body parts and various kinds of tool modules for machining. The efficiency of transparency mapping procedure both in realistic and grid mode is noted. Parametric models of spindle nodes are developed on the basis of dyplexed angular contact ball bearings, established according to the schemes "dyplex" and "triplex". The geometric core of the APM Graph module is used to parametrically set the position of the rod elements and the coordinates of their nodes in the 3D-representations of the machine spindle. Two feedback loops have been introduced in the complementary procedure for spindle modeling related to the change in the types of supports and calculation methods. A study of the efficiency to design of the spindle-boring block assembly by the rigidity criterion is carried out.
