Mechanical claw based on dish-shaped multi-line Archimedes screw pair

Abstract

The invention discloses a mechanical gripper based on a dish-shaped multi-line Archimedes screw pair, which is characterized in that a supporting assembly is rotationally connected with a dish-shaped multi-line Archimedes spiral disc, and a plurality of arc-shaped Archimedes spiral grooves are formed in the dish-shaped multi-line Archimedes spiral disc; the mechanical claw assembly is arranged in the dish-shaped multi-wire Archimedes spiral disk and is fixedly connected with the supporting assembly; the mechanical claw assembly comprises a guide plate, a support and a plurality of claws. The guide plate is connected with the support through the connecting sleeve; guide forks are evenly distributed on the periphery of the guide plate, the middle of the claw is hinged to the support, the upper portion of the claw is in sliding connection with the guide forks, and a ball head matched with the arc-shaped Archimedes spiral groove is arranged on the upper portion of the claw; the driving device is fixedly connected with the supporting assembly, and the output end of the driving device is rotationally connected with the dish-shaped multi-line Archimedes spiral disc. Opening and closing of the mechanical claws are controlled through the disc-shaped multi-line Archimedes spiral disc, and the structure is simple.

Description

technical field [0001] The invention relates to a mechanical claw based on a disc-shaped multi-line Archimedes screw pair, which belongs to the technical field of automation equipment. Background technique [0002] In automatic production, the grasping of parts is an indispensable and important process. There are many types of existing manipulators, each with its own characteristics, and different needs and emphasis requirements in different application scenarios. At present, most manipulators use a cylinder or a motor to directly drive the movement of the jaws through a linkage mechanism. If the cylinder block or the motor encounters a failure or a power failure, it is difficult to guarantee the safety performance of the jaws. [0003] CN 104070529 A, a manipulator based on a spherical screw pair, the manipulator includes a spherical helix, a frame mechanism, a rotating shaft, two claws, two clamping beams and two connecting rods, and the ball helix is ​​arranged on the f...
