Mechanical arm capable of rotating

Abstract

The invention discloses a mechanical arm capable of rotating. The mechanical arm comprises a motor speed reducer, a mechanical arm opening limiting switch, a limiting switch induction block, a mechanical arm closing limiting switch, a gear box, a mechanical arm body, a mechanical arm rotating part fixing unit, a rotating push-pull rod unit, a driving unit, a lead screw, a lead screw nut unit and apower failure brake; a screw nut connecting block of the driving unit is connected with the lead screw and the lead screw nut unit; one end of the rotating push-pull rod unit is connected with the screw nut connecting block, and the other end is connected with the mechanical arm body; the mechanical arm body is mounted on the mechanical arm rotating part fixing unit through a mechanical arm rotating pin; the power failure brake is adopted to lose power to start braking so as to prevent vibration opening of the mechanical arm in the moving process; and through the mechanical arm opening limiting switch and the mechanical arm closing limiting switch, the control unit can automatically judge opening and closing states. The mechanical arm is high in locking structure strength, simple in structure and reliable in work, and widens the application scenes.

Description

technical field [0001] The invention belongs to the field of mechanical arms, in particular to a rotatable mechanical arm used by a wheeled robot. Background technique [0002] With the rapid development of society, cars are becoming more and more popular, but the parking problem that comes with it has become a difficult problem in major and medium cities. In order to solve the problems of difficult and inefficient parking in existing parking lots and new parking lots, the application of intelligent parking robots is becoming more and more common. At present, there are several types of smart robots for accessing cars, such as those with car plates, combs, and robotic arms. In the prior art, the vehicle-carrying plate robot has to always bear the vehicle-carrying plate, which is the lowest in terms of space utilization and transportation efficiency. The comb-tooth robot needs to build a special parking platform, lift the car, and then carry out lifting consignment, resultin...
