Claw type mechanical arm tail end grabbing tool with automatic tolerance positioning function

Abstract

The invention relates to the technical field of robot end instruments, in particular to a claw type mechanical arm end grabbing tool with an automatic tolerance positioning function. The claw type mechanical arm end grabbing tool comprises an upper shell and a lower shell, a hooking mechanism, a driving mechanism and an adsorption structure are arranged in the lower shell, the upper shell is connected with the lower shell through a steel wire rope, the upper shell is provided with a tail end connector used for connecting the grabbing tool to the tail end of a mechanical arm; and a trigger switch is arranged in the lower shell, the grabbing end of the hooking mechanism extends out of the lower shell, the trigger switch is triggered when the adsorption structure is adsorbed to a passive butt-joint grabbing mechanism, and after the trigger switch is triggered, the driving mechanism works to drive the hooking mechanism to be in butt-joint grabbing with the passive butt-joint grabbing mechanism. The claw type mechanical arm end grabbing tool has the advantages that the upper shell and the lower shell are flexibly connected through the steel wire rope, the degree of freedom of the lower shell is increased, precise positioning of the mechanical arm is not needed, and butt joint can be carried out as long as a certain range is reached.

Description

technical field [0001] The invention relates to the technical field of robotic end instruments, in particular to a claw-type mechanical arm end grabbing tool with automatic tolerance positioning. Background technique [0002] Evaporating dish moisture observation is one of the important tasks of scientific research operations, and at the same time, the evaporating dish must be weighed and measured; at present, the observation of evaporating dish is still mainly manual work, and the meteorological evaporating dish is placed outdoors without an accurate location and posture positioning; scientific research robots are mobile robots equipped with mechanical arms, and the geographical conditions of the scientific research station are relatively complex, so it is difficult to achieve accurate positioning of the robot and the mechanical arm relative to the evaporating dish. The meteorological evaporating dish is a cylindrical container with a large volume and After the water is sto...

[0002] The moisture observation of the evaporating pan is one of the important tasks of the scientific research operation, and at the same time, the weighing and measurement of the evaporating pan is required; at present, the observation of the evaporating pan is still mainly manual work, and the meteorological evaporating pan is placed outdoors without an accurate location and posture positioning; the scientific research robot is a mobile robot equipped with a mechanical arm, and the geographical conditions of the scientific research station are relatively complex. It is difficult to achieve accurate positioning of the robot and the mechanical arm relative to the evaporator. After the water is stored, the weight is heavy. At the same time, anti-bird circles are set up around for the needs of scientific research. It is difficult for the mechanical arm to use conventional claws for grasping operations.
