Abstract
The invention relates to a linear-travel electric actuator with adjustable-travel mechanical limiting, comprising an output shaft, a guide nut and a lead screw, wherein a through hole is arranged at the center of a shaft body of the output shaft; the guide nut is internally connected in the through hole of the output shaft; the lead screw is connected in the guide nut in a penetrating manner; and the two ends of the lead screw are provided with movable stopping device. In the linear-travel electric actuator, the structure is simple, the adjustability is strong, the control is convenient, the production and the manufacture are easy, and the cost is low.
Description
Technical field
The present invention 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.
Summary of the invention
The object of the invention 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 present invention's 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.
Advantage of the present invention is: the present invention 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 a structural representation of the present invention.
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 present invention includes output shaft 4, spigot nut 3, screw mandrel 5, 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.
