Abstract
The utility model relates to an adjustable straight travel electric actuator for travel mechanical position limitation. The actuator comprises an output shaft, a guide nut and a screw rod, wherein a through hole is arranged at the shaft body center of the output shaft; the guide nut is internally connected inside the through hole of the output shaft; the screw rod is in penetrating connection inside the guide nut; and movable arresting devices are arranged at both sides of the screw rod. The actuator is simple in structure, strong in adjustability, convenient to control, easy to produce and manufacture and low in cost.
Description
Technical field
The utility model relates to a kind of straight stroke electric final controlling element of adjustable travel mechanical position limitation.
Background technique
YE is claimed electric device for valve again, and is along with the development of wage automation, because of its power source is obtained easily, and Maintenance free generally speaking, more general compared with the equipment of different driving mode such as pneumatic, as to surge.Must possess better reliability and Security at the industrial occasions electric valve.Existing straight stroke electric final controlling element is to rely on electrical appliance part control valve stroke, and cost of production is high, is not easy control.
The model utility content
The utility model purpose be to provide a kind of simple in structure, adjustability strong, be convenient to control, manufacture easily and the straight stroke electric final controlling element of the adjustable travel mechanical position limitation that cost is low.
The technological scheme of the utility model employing is for this reason: comprise output shaft, spigot nut, screw mandrel; Said output shaft axis body center is shaped on a through hole; And connect in the spigot nut with the output shaft through hole in, screw mandrel is connected in the spigot nut, and the screw mandrel two ends are provided with removable stopping device.
Described spigot nut and output shaft are through being threaded.
Said screw mandrel is connected through trapezoidal thread with spigot nut.
Said stopping device is last retainer nut and following retainer nut.
Said screw mandrel and stopping device be through being threaded, and pass through screw.
The utility model has the advantages that: the utility model is simple in structure, adjustability is strong, be convenient to control, the manufacturing is easy and cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is that screw, 2 is that last retainer nut, 3 is that spigot nut, 4 is that output shaft, 5 is that retainer nut, 7 was that clutch cover, 8 is that worm gear, 9 is that worm screw, 10 is that gear on worm, 11 is that motor gear, 12 is a motor under screw mandrel, 6 was among the figure.
Embodiment
The utility model comprises output shaft 4, spigot nut 3, screw mandrel 5, and said output shaft 4 axis body centers are shaped on a through hole, and connect in the spigot nut 3 with output shaft 4 through holes in, screw mandrel 5 is connected in the spigot nut 3, and screw mandrel 5 two ends are provided with removable stopping device.Described spigot nut 3 and output shaft 4 are through being threaded.Said screw mandrel 5 and spigot nut 3 are connected through trapezoidal thread.Said stopping device is last retainer nut 2 and following retainer nut 6.Said screw mandrel 5 and stopping device be through being threaded, and fixing through screw 1.
After motor 12 rotates; Drive gears on worm 10 through motor gear 11 and rotate, thereby driven the rotation of worm screw 9, worm gear 8, and drive output shafts 4 through clutch cover 7 and rotate; Because output shaft 4 is threaded with spigot nut 3; And fastening through screw 1, spigot nut 3 rotates with output shaft 4, promotes screw mandrel 5 through trapezoidal thread and moves up and down.Screw mandrel 5 two ends are respectively equipped with retainer nut 2 and following retainer nut 6, and connect through screw 1, thereby have limited the stroke that moves up and down of screw mandrel 5, can regulate according to actual conditions and go up retainer nut 2 and the position of following retainer nut 6 on screw mandrel.
