A guide disc friction manipulator claw

Abstract

The invention provides a guide disc friction mechanical paw which comprises a driving motor, a motor base fixed to the driving motor, a guide disc fixed to a driving shaft of the driving motor, a limiting clamp fixed to the motor base and a paw body which stretches into the limiting clamp and is in contact with the guide disc. The back face of the guide disc is fixed to the driving shaft, two arc grooves which are in central symmetry relative to the guide disc are formed in the front face of the guide disc, arcs of the arc grooves are contracted towards the center from the edge of the guide disc, and the radiuses of the arcs are smaller when the arcs are close to the center. The limiting clamp comprises two parallel limiting plates. The paw body comprises two crossed special-shaped rods, a sliding end and a clamping end are arranged at the two ends of each rod respectively, the sliding ends stretch into the limiting clamp and are in contact with the guide disc, the clamping ends stretch out of the limiting clamp, and the crossed position is movably riveted with the two limiting plates. The driving shaft rotates to drive the guide disc to rotate, the two sliding ends slide along the arc grooves, and the two clamping ends are opened and closed. The paw has the advantages of being simple in structure, high in paw strength, large and stable in grabbing force, high in grabbing precision, easy and convenient to control, low in cost and the like.

Description

technical field [0001] The invention relates to a manipulator claw, in particular to a guide disc friction manipulator claw. Background technique [0002] With the rapid development of robotics technology, many countries have invested more and more research in the field of robotics, and have also achieved a lot of results. Among them, the use of robots to carry and grab objects is a key point in the use of robots. Robot claws are a very important part of the entire structure of robots as actuators. [0003] At present, robot grippers mainly include clamp structure, wedge structure, quadrilateral structure and worm gear structure: [0004] The clamp-type mechanical claw is characterized by flexible movement, large clamping range, and can change the opening, but it has no self-locking ability and low precision; [0005] The wedge-type manipulator claw is characterized by a simple mechanism and is suitable for clamping small and medium-sized workpieces, but its grasping force...
