Passive manipulator

Abstract

The invention relates to a passive manipulator. The passive manipulator comprises a mechanical arm, at least two clamping jaws, a clamping jaw locking mechanism and a clamping jaw seat positioned below the mechanical arm, wherein each clamping jaw comprises a clamping rod and a clamping head connected to the front end of the clamping rod. The clamping jaw seat is movably connected with the mechanical arm and can move up and down relative to the mechanical arm, the clamping rod is provided with a first connecting point and a second connecting point, the first connecting point is positioned between the clamping head and the second connecting point, the first connecting point is hinged on the clamping jaw seat, and the second connecting point is movably connected with the mechanical arm. Theclamping jaw locking mechanism comprises a locking hook and a guiding and locking structure, wherein the locking hook, the guiding and locking structure are separately arranged on the clamping jaw seat and the mechanical arm, the guiding and locking structure comprises a locking groove and a guiding structure for guiding the locking hook to move into the locking groove and to disengage from the locking groove, and the clamping jaws do not need a driving mechanism with a power source to drive when carrying out clamping and loosening actions, the passive manipulator is compact in overall structure, small in volume, low in cost, and has high explosion-proof safety.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to a passive manipulator. Background technique [0002] In order to pursue higher production efficiency, more and more occasions have begun to use manipulators to replace the original manual work, such as item transfer work. Most of the existing item transfer manipulators use active manipulators, that is, such manipulators need to be connected to the power source. The driving mechanism is used to drive the movement of the jaws (the opening and closing of the jaws does not require a manipulator driven by a power source, called a passive manipulator), so as to realize the clamping and loosening of the item. [0003] For a manipulator that relies on electric power to drive the gripper, if it is to be applied to the grasping of flammable and explosive items, it is necessary to design an explosion-proof design for the electrical part to prevent the electric sparks generated ...

AI Technical Summary

Problems solved by technology

[0004] In general, whether electric power or compressed gas or liquid is used to drive the movement of the jaws, it is necessary to equip the jaws of the manipulator with a drive mechanism with a power source, which will lead to the following problems: 1. The structure of the manipulator becomes complicated and the volume relatively bigger

2. The cost of the manipulator is relatively high
