Description
Technical field
The utility model relates to screw-drive mechanism in machine applications, belongs to mechanical transmission, is mainly used in transmission during worktable ultralong-stroke in machine driven system.
Background technique
In machine driven system, the transmission of worktable ultralong-stroke generally uses hydraulic transmission, rack and pinion drive mechanism, wherein hydraulic transmission driving force is large steadily but can not ensure positioning precision, rack and pinion drive mechanism is that open type mechanism is unfavorable for lubrication, the ball screw auxiliary drive gear that conventional screw mandrel rotates, the wattless power driving screw mandrel to rotate is large.
Summary of the invention
For better realizing highi degree of accuracy and the high efficiency of mechanical spiral driving mechanism, the utility model provides a kind of ultralong-stroke screw-drive mechanism, screw mandrel is fixed stretching by this mechanism, and nut rotates, and pair of nut realizes the motion of work director distance under driven by servomotor.Stable drive is reliable, screw mandrel influence of thermal deformation is little, transmission accuracy is high.
The technical solution of the utility model is: for mechanical ultralong-stroke screw-drive mechanism, comprises locking nut, end cap, bearing, ball wire bar pair, synchronous pulley, bearing pack, supporting sleeve, electric machine support, worktable, Timing Belt, swelling female connector, regulating base board, actuating motor.The screw mandrel two ends of described ball wire bar pair are installed in the holder by end cap, the locking nut at screw mandrel two ends is stretching by screw mandrel, the nut portion of described ball wire bar pair is arranged on supporting sleeve by bearing pack, supporting sleeve is fixed on electric machine support, on the nut that described synchronous pulley is arranged on ball wire bar pair respectively and actuating motor, Timing Belt connects two synchronous pulley runnings, described actuating motor is connected in electric machine support by regulating base board, and electric machine support is connected with worktable by screw.
During application, rotary motion is passed to the nut of ball wire bar pair by actuating motor by toothed belt transmission, ball screw does not rotate, axially move in the nut rotation of ball screw, by bearing and supporting sleeve structure drive motor base plate, electric baseboard drives movable workbench, and because ball screw is not taken exercises, this structure can realize the movement travel of overlength.
