Description
Technical Field
The utility model belongs to electromagnetic force application, especially, electromagnetism push-and-pull constant force telescopic link device.
Background
In industrial automation, intelligent automation devices, actuator devices are often required: the telescopic displacement of the linear distance is executed, and the adaptability of certain force is kept, especially the constant force which is not changed much is kept in a certain distance. The existing similar products have complex structures and high production cost, and are not easy to popularize and use.
Disclosure of Invention
The utility model aims at providing an electromagnetism push-and-pull constant force telescopic link device that simple structure, safe and reliable, cost of manufacture are low, range of application is wide.
The utility model discloses an electromagnetism push-and-pull constant force telescopic link device, including support, electromagnetism solenoid, solenoid skeleton, wire, controller, the electromagnetism solenoid passes through the solenoid skeleton to be installed in the support, and the controller passes through the wire and links to each other with the electromagnetism solenoid, and its characterized in that, symmetrical left supporting sleeve, right supporting sleeve of setting up on the support, the flexible body of rod passes the central axis of electromagnetism solenoid and bears on left supporting sleeve, right supporting sleeve, and can follow the movement of left and right supporting sleeve axle center direction; the telescopic rod body is of a hollow structure, a left ferromagnetic body and a right ferromagnetic body are arranged in a hollow cavity of the telescopic rod body, the left ferromagnetic body and the right ferromagnetic body are close together, the polarities of the contact ends of the left ferromagnetic body and the right ferromagnetic body are the same, and one end of the telescopic rod body is a load mounting head and is used for being connected with a load.
The utility model discloses an electromagnetism push-and-pull constant force telescopic link device theory of operation is, when controlling means sent the electric current of change to the electromagnetism solenoid, the magnetic field that the electron solenoid produced acted on the internal left and right sides strong magnetic body of telescopic link and produced the displacement, drove the flexible body of rod along the motion of supporting sleeve axis direction. As shown in fig. 3, after the electromagnetic coil is energized with a forward direct current, an SN magnetic pole is generated, and the SN magnetic pole and the NS pole of the left strong magnetic body are attracted to each other rapidly, so as to pull the telescopic rod body to move to the left and stay at the position of fig. 3. The N pole of the electromagnetic coil is aligned with the S pole of the left strong magnet, the N pole of the S pole of the left strong magnet is aligned, and at the moment, the telescopic rod body is in a static stable state. If the telescopic rod body is pushed to the left by applying force on the right side of the telescopic rod body, the telescopic rod body moves to the left against the attraction of magnetic force, the N pole of the left ferromagnetic body leaves the S pole of the electromagnetic coil, and the S pole of the left ferromagnetic body leaves the N pole of the electromagnetic coil and is close to the S pole of the electromagnetic coil. At the same time, the S pole of the right ferromagnetic body is away from the N pole of the electromagnetic coil and close to the S pole of the electromagnetic coil, and the N pole of the right ferromagnetic body and the N pole of the electromagnetic coil are close, and the attraction force and the repulsion force act together, and the force is in a substantially constant force state within a distance. As shown in fig. 4, when negative direct current is applied to the electromagnetic coil, the magnetic pole of the electromagnetic coil changes from SN to NS, but the magnetic pole of the ferromagnetic body does not change, the direction of the movement is opposite, and the magnetic pole stays at the position shown in fig. 4. When the current and the direction of the electromagnetic solenoid coil are changed under the control of the control device, the moving distance and the force of the telescopic rod body are changed along with the change, when the frequency of the change of the current direction is higher to a certain degree, the telescopic rod body can vibrate along the axial direction of the supporting sleeve, and the vibration frequency is set by the control device.
The utility model discloses an electromagnetism push-and-pull constant force telescopic link device has simple structure, safe and reliable, cost of manufacture low grade advantage, and under electronic control, the device can stretch out and draw back in the certain limit, and can shake fast, satisfies the needs that the difference was used. The device can be applied to the fields of industrial equipment, military equipment, household electrical appliance equipment and the like, and is particularly applied to the aspects of constant force stretching and vibration massage in the intelligent application of household electrical appliances.
