Abstract
The invention discloses a telescopic electric push rod. The telescopic electric push rod is aimed to solve the problem that an existing telescopic electric push rod is incapable of detecting the push-pull force acted on load in real time so that the existing telescopic electric push rod is difficult to meet higher demands. The telescopic electric push rod improves the structure, a force sensor is arranged on the end of a telescopic rod, the sensor serves as a force transmission piece between the telescopic rod and the load and also serves as a force detection piece, the stress situation on the load is detected in real time through the force sensor so as to meet higher use demands, for example, the force intensity can be detected in real time, the peak value of the push-pull force is settable, and the electric push rod automatically stops working when the push-pull force arrives at peak value; the telescopic electric push rod achieves the purposes of protecting the load and realizing higher control.
Description
Technical field
The present invention relates to a kind of electric pushrod, particularly relate to a kind of telescopic electric push rod.
Background technology
Now, often need to adopt telescopic electric push rod in some industries such as furniture industry or medical electronic pulling equipment, telescopic electric push rod has an expansion link, the rod end of load and expansion link is connected and fixed, during electric pushrod work, drive expansion link to stretch by motor, thus realize various function.Problem is, telescopic electric push rod now can not detect in real time to the push-pull effort acted in load, is thus difficult to meet higher requirement.
Summary of the invention
In order to the telescopic electric push rod solved now can not detect the push-pull effort acted in load at any time in real time, thus the problem meeting higher requirement is difficult to, the structure of the present invention to telescopic electric push rod is improved, the termination of expansion link arranges force snesor, make transducer both as the power transmission part between expansion link and load, again as power detection piece, detected in real time by the stressing conditions of force snesor to load, to meet higher instructions for use, such as can the size of detect force in real time, the peak value of push-pull effort can also be set, electric pushrod is quit work automatically when push-pull effort reaches peak value.
The present invention's adopted technical scheme of dealing with problems is: a kind of telescopic electric push rod, primarily of the body of rod, power supply, the component compositions such as hand controller, the body of rod is provided with motor, expansion link, body of rod inside is provided with transmission component, screw rod, travel control switch, also be provided with mount pad, the body of rod is installed fixing by mount pad, motor by transmission component drive screw turns and drive expansion link stretch, it is characterized in that, the termination of described expansion link is also provided with force snesor, described force snesor one end is connected with expansion link and the other end is connected with load, power is passed to load by force snesor by expansion link.
Preferred version of the present invention: one end of described force snesor is provided with expansion link link and the other end is provided with load link.
Preferred version of the present invention: the expansion link link grafting of described force snesor is also fixed on expansion link termination.
The invention has the beneficial effects as follows: the present invention is by improving the structure of telescopic electric push rod, expansion link termination arranges force snesor, make it as the power transmission part between expansion link and load and detection piece, detected in real time by the stressing conditions of force snesor to load, to meet higher instructions for use, except can the size of detect force in real time, can also coordinate with other necessary instrument, such as utilize the peak value test instrument of force snesor, by arranging peak value, make electric pushrod automatically out of service when push-pull effort reaches peak value.
