If push rod is rigid posts in the utility model electromagnetism joint Manipulator, the bending force between spring elimination push rod top and upper plate can be utilized.
In the utility model electromagnetism joint Manipulator, flexible push rod then can eliminate the bending force between push rod top and upper plate voluntarily.But flexible link is easily friction mutually in flexible sleeve, or produces skew, then arrange spacing ring and carry out spacing to permanent magnet, play the guiding role in passing to flexible push rod.
In the utility model electromagnetism joint Manipulator, if desired expansion link has enough extending forces, then certainly will will add the magnetic of powerful electromagents.But three expansion links hypotelorism after all, mutual interference easily causes driving chaotic, then on the barrel of flexible sleeve, coaxial spaced embeds the mutual interference that ring shielding magnetism can reduce by three expansion links, and the magnetic screen thin slice ring of 0.0508 millimeters thick that what Mumetal material can make only have, then its frivolous performance does not affect the degree of crook of expansion link, and is electromagnetic flexible joint loss of weight.Interval between ring shielding magnetism is greater than ring shielding magnetism height 1/5, then do not reach good Magnetic Shielding Effectiveness.During use; one of them magnetic induction line wire cutting coil because of the non-conductively-closed between ring shielding magnetism of first battery, the second battery, thus to its power supply, another discharges to the electromagnet of telescopic mast; interleaved power, electric discharge can work while charge, the protection life of storage battery.
It is the contact of a point and face that the utility model electromagnetism joint Manipulator mid point limit cover contacts with each other, and its advantage is flexible for turning to.
In the utility model electromagnetism joint Manipulator, face limit cover contacts with each other is an elongated cambered surface.Its advantage is for keeping attitude comparatively stable.
In the grasping means of the utility model electromagnetism joint Manipulator, the degree of crook of simulating human hand regulates the electromagnetic flexible joint of different number to contact, and can copy staff manufacturing machine hand to greatest extent, make its purposes more extensive.
Below in conjunction with accompanying drawing, electromagnetism joint Manipulator of the present utility model is described further.
