The Research Of Built-in Deep-hole Processing Step Robot

In this paper, because long deep hole machining tube is difficult to process, so, a deep-hole machining robot to raise, and designed the robot. This deep-hole processing robot inherits the traditional advantages of deep-hole processing methods on the basis of the deep hole for the difficult process with the general processing of ultra-long tube design. The robot can be deep-processing pipe wall or to semi-finishing work to deal with rust, and because of its small size, easy handling, it will be convenient to carry out the processing in the current. Basic use of the entire robot system hydraulic drive and control, manufacturing convenience, cheaper prices, the feasibility of a high.In this paper, deep-hole machining of mechanical systems and robot-driven system design of the whole body structure and mechanical design and study specific. In Pro/E three-dimensional modeling software to use technology to build a three-dimensional solid model, and model of quality, space and interference detection, designed to verify the correctness of the overall structure and rationality. At the same time, the robot head, tail, shaft, support legs and the selection of bearings for the specific design and analysis. The establishment of the robot in the process of cutting mechanics model and calculated based on the size of the cutting force required to calculate the motor power.In order to ensure the machining precision tube, according to metal-cutting in the flutter phenomenon in the cutting of the robot due to the speed of feedback and displacement caused by delayed feedback phenomena flutter analysis, and proposed a number of damping, damper measures. At the same time, in ideal circumstances, the establishment of the robot vibration model to support the foot and on the basis of metal-cutting mode coupling in the principle of flutter vibration model of the foot support an analysis has been to reduce and eliminate some of the methods of vibration .The use of ADAMS simulation software for the robot kinematics and dynamics simulation, through the campaign to determine the limited space within the mutual interference; movement by setting the required parameters, the realization of the robot walking and cutting process. According to the kinetic parameters has been a key part of the dynamic analysis results, a reasonable choice as a means of power-driven motor.
