The Design Of The Numerical Control System For Cranshaft Chamfer Rolling And The Imitation Of Movement Base On The Software-Solidworks

The rolling process for strengthening crankshaft chamfer is the best way to strengthen the surface of crankshaft chamfer at the present time. By this way, the fatigue life-span of crankshaft would increase obviously, furthermore, the good quality of surface can be accepted after the rolling process if the choused parameters are rational and the lubrication is good, the rolling chamfer can meet to the require of the surface quality and does not need to be ground finely, thus, this process is propitious to enhance the productivity and reduce the final cost .The main work of this paper as follows:On the base of research of mechanism of rolling and loading-mode of rolling, according to the roll process, we design the numerical control system of rolling, study the numerical control plan and study out the procesure list.According to the blue print of numerical control system, we finish the designand choice of hardware system, Including servo electromotor-computer system (servomechanism, servo electromotor, two axis and four axis moving control card), electric bow wave displacement sensor, numerical I/O card.With the program interface provided by the movement control card and numerical I/O card, we exploit the software based on the windows operating system, including the interface design of program, realization of I/O function, realization of closed loop control arithmetic.Finally, we establish three dimension model of crankshaft and rolling sword bythe software-solidworkso After that, we exploit the software-solidworkssecondly using vc++, realize the dynamic imitation of machining procedure.In this paper, the panoramic design on numerical control in N4850Q crankshaft rolling machine tool islaidouto At the same time, we design the software and hardware of numerical system, realize the rolling machining of crankshaft and the imitation of machining procedure.
