Technical Field

The invention belongs to the field of electromagnetic force application, and particularly relates to an electromagnetic push-pull constant-force telescopic rod 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 invention aims to provide an electromagnetic push-pull constant-force telescopic rod device which is simple in structure, safe, reliable, low in manufacturing cost and wide in application range.

The invention relates to an electromagnetic push-pull constant-force telescopic rod device which comprises a support, an electromagnetic coil, a coil framework, a lead and a controller, wherein the electromagnetic coil is arranged in the support through the coil framework; 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 working principle of the electromagnetic push-pull constant-force telescopic rod device is that when the control device sends a changing current to the electromagnetic coil, a magnetic field generated by the electronic coil acts on left and right strong magnets in the telescopic rod body to generate displacement, and the telescopic rod body is driven to move along the axial direction of the supporting sleeve. 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 electromagnetic push-pull constant-force telescopic rod device has the advantages of simple structure, safety, reliability, low manufacturing cost and the like, can extend and contract within a certain range under electronic control, can vibrate quickly, and meets the requirements of different applications. 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.
