Abstract

The invention discloses a bionic elephant trunk mechanical arm. The bionic elephant trunk mechanical arm comprises a base and an end flange. A plurality of basic motion groups are arranged between thebase and the end flange. The plurality of basic motion groups are connected through universal couplings. Servo motors on the base are connected with the bottom of the first basic motion group throughuniversal couplings. The top of the basic motion group located at the tail end is connected with the end flange through universal couplings. Each basic motion group comprises a unit connecting plate,a plurality of linear motion units and a driven telescopic unit, wherein the unit connecting plate is provided with mounting holes; the driven telescopic unit is mounted in the mounting hole in the center position; and the plurality of linear motion units are uniformly distributed in the mounting holes located on the edge around the driven telescopic unit. The bionic elephant trunk mechanical armachieves the elephant trunk bending function through the length difference and realizes changes of the overall length through linkage. Moreover, the function of simulating twisting of an elephant trunk is added, and simulation of the elephant trunk functional structure is realized. The bionic elephant trunk mechanical arm provided by the invention has the advantages of high control precision andlarge operation space.

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 ...
