Research Of Walking Way And Deep-hole Boring Robot System And Vibration Analysis

With the rapid development of modern manufacturing, deep-hole boring processing technology from the initial defense industry has penetrated into all fields of equipment manufacturing industry. Deep Hole is not a simple process to extend the shallow hole, its processing difficult and the workload is a key machining processes. The topic for the deep processing of difficult to machine with long tube phenomena,to design a large diameter pipe in deep hole processing device, the device is placed deep within the boring head for processing step built-in deep hole boring robot. The deep hole machining robot not only on the tube wall can be used for roughing and semi-finishing, and the tube wall can rust or scale removal and so on. In the inherited advantages of the traditional methods of deep processing, based on deep processing of the processing robot also has great depth,small,and easy handling.In this paper, the machinery structure and deep processing of step principles of robot design and research, draw a specific design. In the Pro/E 3D modeling software used to establish a three-dimensional solid model, the quality of the model, clearance and interference detection, verification of the correctness of the overall structure of the design and reasonable. At the same time with the completion of the whole machine virtual assembly, virtual assembly simulation using ADAMS software robot kinematics simulation of the model is static interference tests show that this design enables the robot to walk inside the tube and cutting processing, to meet the technical requirements. The establishment of a solid model is a foundation for future dynamic analysis.To ensure the normal process, verify the robot mechanical structure design is reasonable and processing stability and the enhanced processing precision tube, build on the solid model, using finite element method, Application of large-scale commercial software ANSYS10.0, for the overall structure and spindle assembly robot finite element analysis and calculation. By modal analysis, obtained the first 10 orders of natural frequencies and mode shapes, the experimental results in order to avoid the vicinity of its resonant frequency to provide the parameters for; by the dynamic response analysis of the body structure to withstand change over time cutting force frequency response under the circumstances to obtain the largest institutions in the work of displacement and dynamic stiffness, in order to test the rationality of the structure provides a theoretical basis. Based on the analysis put forward to upgrade the deep processing of robot stability of the basic way, in order to further improve the structure of the robot itself provide the basis, so that machine's dynamic performance is improved.
