Embodiment
Electric pushrod of the present utility model as shown in Figure 1 to Figure 3, comprises motor 1, decelerator 2, the outer sleeve 4, the screw pair that are connected with bearing pedestal 3 and inner core 5 and the joint thereof being installed together with it.Screw pair comprises leading screw 6 and feed screw nut 7, and nut is fixedly connected with inner core 5, can, along leading screw 6, on urceolus 4 is interior, move, and leading screw 6 use bolts are mounted on bearing pedestal.Motor 1 drives decelerator 2 to rotate, and by bearing pedestal 3, leading screw 6 is rotated, and moves axially thereby realize feed screw nut 7, and the positive and negative rotation of motor 1 realizes the flexible back and forth of electric pushrod.
Bearing pedestal 3 each side have an installation axle hole 8, its axial direction has a pair of taper roll bearing 9 of installation and fixes, locates the axle sleeve of use and the axis hole of fixing back-up ring, on the end face that bearing pedestal 3 and reductor 2 are installed, has slotted eye, forms and coordinates with decelerator 2, convenient location, installs.
On outer sleeve 4, there are three photoelectric sensors, two of rear and front end are used for respectively the limit position sensor 10,11 of the extreme position that detects screw mandrel motion, another is used for defining the dead-center position approach switch 12 of screw mandrel initial position, ensures the accurate control that screw mandrel stroke moves.Urceolus 4 one end and bearing pedestal 3 are bolted, and the other end is provided with ring flange 13, have pair of O type circle and a pair of bearing shell in it, and inner core 5 is in the interior slip of urceolus 4.
Operation principle: starter motor 1; motor 1 drives decelerator 2 to rotate; decelerator 2 drives the feed screw nut 7 that leading screw 33 connects to move; nut 7 promotes inner core 5 and moves linearly hollow sleeve cylinder 4 is interior, and in the time that nut 7 moves to forward and backward extreme position, the extreme position approach switch 10,11 on urceolus 4 starts effect; power-off; disable motor drives, thereby the ball in the connection of protection leading screw comes off, and ensures the normal work of mechanism.At the front end of urceolus 4, the sliding extension that ring flange 13 also can be used for supporting inner core 5 is installed.When the every task of electric pushrod, first confirm the initial position of leading screw 6, this is to have been detected by the dead-center position approach switch 12 on urceolus 4. the decelerator 2 that the utility model adopts is auto-lock functions that worm type of reduction gearing, drive motors 1 and the less rational helical angle of feed screw nut pair employing can realize electric pushrod, ensures safety, the reliability of work.
