Abstract
This utility model discloses an end-effector puncture mechanism for a targeted puncture robot, relating to the field of robotics. It includes a target support, a fixed frame, and a first motor. The fixed frame is mounted on the top of the target support, and a guide sleeve is mounted on one side of the fixed frame via a mounting bracket. The fixed frame has slots on both sides inside, and slide rails are provided on the inner walls of the slots. A housing is provided inside the slide rails, and a second motor is housed inside the housing. A transmission wheel is mounted on the output end of the second motor via a coupling. The first motor is mounted on one side of the fixed frame, and a fixed shaft is mounted on the output end of the first motor via a coupling. A concave cross-shaped neodymium magnet is provided on the inner wall of the fixed shaft. The device allows a rotating knob to drive a forward and reverse lead screw, which in turn moves a moving block up and down. This, in turn, allows the second motor to adjust the distance between the transmission wheels, facilitating the guidance of puncture needles of different diameters.
