Summary of the invention
The purpose of this utility model provides the numerical control Internal Spherical Surface grinding machine of a kind of precision height, working (machining) efficiency height, good reliability.
The technical scheme that realizes above-mentioned purpose is: a kind of numerical control Internal Spherical Surface grinding machine, comprise lathe bed, length feed planker and drive its ball-screw, traverse feed planker and drive its ball-screw, guide rail, dresser, centralizer, spindle inverters, lubricating system, regulator cubicle and digital control system, also comprise AC servomotor, AC servo control system and high-speed electric main shaft, AC servomotor is connected with the ball-screw that drives the traverse feed planker by shaft coupling, on the output shaft of AC servomotor synchronous pulley is housed, on the ball-screw of drive length feed planker synchronous pulley is installed, synchronous pulley is connected by being with synchronously with synchronous pulley, and high-speed electric main shaft is positioned on the traverse feed planker.
After adopting technique scheme, the control mode of digital control system, AC servo control system, AC servomotor, ball-screw has replaced the control form of " the PLC+ hydraulic pressure " in the known technology, improve part processing precision greatly, improved part processing efficient.After adopting high-speed electric main shaft, the speed of mainshaft has been brought up to more than 18000 rev/mins, not only shortens man-hour, raises the efficiency, and the more important thing is that the surface smoothness of part obtains the raising of essence.By adopting high accuracy, gapless drive disk assemblies such as ball-screw, high-speed electric main shaft, shaft coupling, synchronous band, solved the processing consistency problem of grinding machine.
