This machine tool has good grinding effect on three-dimensional curved surfaces, stable work, simple structure and easy operate.
Description
Technical field
The present invention relates to a kind of grinding machine, particularly about being exclusively used in the abrasive belt grinding machine of grinding curved surface.
Background technology
At present, it is that machine adds the processing step that often runs in the operation that the curved surface mill drives, particularly when producing turbine blade, must carry out grinding to its surface, to reach certain smooth degree, be intended to the resistance that reduces friction in the motion, reduce kinetic equation loss, for this purpose, currently used grinding machine, surface grinding machine, curve surface grinder, numerically control grinder are arranged, though play a part necessarily in grinding, when having the blade surface grinding of three-dimension curved surface, what have is not too suitable, the complicated operation that has, the inefficiency that has.
Summary of the invention
The present invention is directed to the prior art weak point, provide a kind of can the grinding three-dimension curved surface, operate steadily freely, the abrasive band is easy to change, novel structure, simple to operate, cost is low, maintaining is abrasive band curve surface grinder easily.
For solving its technical problem, the technical scheme that is adopted is: bed body top is provided with fixed platform, fixed platform is provided with the parallel mechanism of being made up of the gate-type connecting rod, the parallel mechanism lower end links to each other with motion platform, end is provided with drive rod about fixed platform, the drive rod lower end links to each other with motion platform end face central part, the motion platform transverse plane is provided with the bistrique support, the bistrique support is provided with driving wheel, driven pulley, grinding belt is housed on the two-wheeled, forms the sand pocket bistrique, asynchronous machine is fixed on the bistrique support, the asynchronous machine output shaft links to each other with drive sprocket axle, abrasive band bistrique lower space is provided with by turntable, tailstock and the part processing seat that vertically moves the workbench composition, the part processing seat is arranged on the body base plane, and turntable is provided with servomotor.
The present invention has following advantage compared to existing technology:
Because adopt parallel mechanism to connect between fixed platform and the motion platform, motion platform can be done upper and lower or left and right direction translational motion;
Owing to one group of abrasive band bistrique is installed on the motion platform, under normal asynchronous drives, workpiece is carried out grinding around driving wheel and driven pulley high speed rotating;
Because turntable is provided with servomotor drive work piece and can slowly turns round, and carries out curve surface grinding.
Because tailstock can be along the longitudinal movement and and turntable be installed in to vertically move on the workbench and vertically move, so can adapt to the processing of different length spare.
