Research On Table Band Sawing Machine Curve Feeding Mechanism And Digital Control Implementation

The control technology for the curve sawing of the table band sawing machine, not only can implementation the automatic curve feeding to avoid the accident caused by the artificial delivery, still can greatly improve the processing precision and work efficiency. It has a very important significance in the furniture manufacturing industry.Firstly through the investigation and study on the relevant documents, this paper analyzed the domestic and overseas development of existing curve sawing technology, and the technology and methods of curve sawing processing, then proposed the Execute Solution of the table band sawing machine curve feeding mechanism, designed the general structure of the curve feeding mechanism, and introduced in detail the structure and enforcement mode of the mechanism;By studying on the main mechanism, divided into the two parts of XY orthogonal translation mechanism and deflection mechanism, established respectively the kinematics model, proceed the positive kinematics analysis and the inverse kinematics analysis to get the position equations of the curve feeding mechanism, and then solved these position equations; It laid a theoretical foundation for the study on mechanism optimization, error analysis and control algorithm of the curve feeding mechanism;Using ADAMS software established the3d model of the mechanism. With the reverse analytical method of ADAMS, got the curves of all axial feed through the simulation measure, then got the real-time control information of each shaft by data processing of these curves, and then loaded these control information to the drive of each shaft to simulate the curve sawing process;The last finished the preliminary design and research on the numerical control system of table band sawing machine curve feeding mechanism from two aspects of hardware and software, expounded the work process of numerical control system, including drawing and reading of the processing curve, calculating of control information, verification of sawing trajectory, creating and executing of the control code; then implementation the computer control of table band sawing machine curve feeding mechanism.
