Examples

During normal operation, the self-adjusting anti-collision actuator needs to be connected correctly: the actuator moving platform 1 is connected with an end tool, and the actuator static platform 2 is connected with a universal mechanical arm.
A preparation stage: hollow ring type electromagnets 3-11 in the six actuator bearing rods 3 are in an electrified state and adsorb the piston compression rods 3-4, and the whole bearing parallel actuator is in a rigid state. The compression springs 3-7 are adjusted to the appropriate amount of compression by tightening nuts 3-6 and spring upper trays 3-13.
