Problems solved by technology

However, the bionic elephant trunk disclosed in this patent has great limitations. For industrial operations that require precise positioning, the operation of the inflation operation is obviously poor in control accuracy, and it is impossible to achieve synchronous precision control for each node. In actual operation Prone to large positioning and grasping errors

Abstract

The invention discloses a bionic elephant trunk mechanical arm, which includes a base and an end flange, a basic motion group between the base and the end flange, several basic motion groups are connected by universal couplings, and a servo motor on the base passes through The universal coupling is connected to the bottom of the first basic motion group, and the top of the basic motion group placed at the end is connected to the end flange through a universal coupling; the basic motion group includes a unit connecting plate, a linear motion unit and a driven The telescopic unit has a mounting hole on the connecting plate of the unit, and the driven telescopic unit is installed in the mounting hole at the center, and several linear motion units are evenly distributed in the mounting holes around the driven telescopic unit. The invention realizes the bending function of the elephant trunk through the length difference, realizes the overall length change through linkage, and increases the twisting function of the simulated elephant trunk to realize the simulation of the functional structure of the trunk. Large bionic elephant trunk arm.

Description

technical field [0001] The invention relates to a mechanical arm, in particular to a bionic elephant trunk mechanical arm. Background technique [0002] In the process of using the elephant trunk to grasp objects, the length difference is produced by the contraction of muscles in different parts, which makes the elephant trunk bend and deform. The elephant trunk changes the length of the elephant trunk through the expansion and contraction of the sphincter muscle. The elongation rate is about 20%-30%, and the trunk is twisted through the contraction of the spiral muscle. Therefore, many companies design the bionic trunk mechanical structure instead of the mechanical arm according to the principle of the elephant trunk. At present, the working space of the existing parallel robot is smaller than that of the serial robot, and the accuracy loss of the serial robot is relatively large due to the multi-section open-loop chain structure, and the application of the bionic elephant ...
