Small Deep Hole Drilling System And Analysis Of Its Dynamic Characteristics

As everyone knows, gun drilling as an effective way of deep hole processing, its effect isobviously. In this paper, the processing performance of the original, witha company in Shanximachinery manufacturing efficiency of small deep holedrilling inclined machinereconstruction project for a small deep hole drill pipearound the deviation were analyzed, putforward the reconstruction of machine tool is feasible and the structure design and analysis ofdynamic.High efficiency drilling inclined small deep hole machine reconstruction project toincrease the pressure of coolant supply, high pressure cooling system, automatic chip system,gun drilling system, servo motor and its connecting device, and has automatic chip chipbreaking function, which can finish one-time molding processing on PCrNi3MoVA mediumcarbon low alloy quenched and tempered steel, guarantee automatic chip removal function ofgun drilling system feasibility. To ensure product quality and efficiency of processing.Principles of eccentric rotor in rotor dynamics of the whole system of gun drilling wereused to the system dynamics modeling. The modal analysis for gun drilling system wascarried by the use of WorkBench to calculate the natural frequencies and mode shapesensuring no gun drilling system resonance conditions in the incentive effect.Secondly, thenumerical analysis to the entire drilling system were carried by using ODE45arithmetic inMATLAB, the response diagrams to reflect the vibration for the dynamic characteristics ofgun drilling system under different speeds and different cutting parameters were got to verifythe rationality of small gun drill deep hole drilling systems...
