Polar coordinate type simple pneumatic mechanical hand

Abstract

The invention discloses a polar coordinate type simple pneumatic mechanical hand which consists of a rotary table, a base, a paw, a telescopic air cylinder rod, a telescopic air cylinder, a pitching air cylinder rod and a pitching air cylinder. A stand column is mounted on the rotary table; the telescopic air cylinder is hinged with the stand column and the air cylinder rod of the pitching air cylinder through hinges; the air cylinder body of the pitching air cylinder is connected with the stand column through a hinge; the paw is mounted on the air cylinder rod of the telescopic air cylinder; and the rotary table is connected with a rotary air cylinder in the base. The polar coordinate type simple pneumatic mechanical hand disclosed by the invention has the advantage that a structure for realizing pitching motion of an arm is relatively simple, and the need of locating the mechanical hand can be realized by controlling the air cylinders to move and stop, so that the polar coordinate type simple pneumatic mechanical hand has the characteristics of low cost, a simple structure and convenient maintenance.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a polar coordinate type simple pneumatic manipulator. Background technique [0002] With the wide application of manipulator technology, general-purpose teaching manipulators with independent controllers, flexible actions, and suitable for experimental teaching in colleges and universities have developed rapidly. The manipulator has good control performance and fast response, but the cost is high; most of the existing pneumatically driven teaching manipulators are Cartesian coordinate manipulators, and the Cartesian coordinate manipulators are more complicated in structure and difficult to maintain. However, the teaching-type universal manipulator with low cost, convenient maintenance, and easy learning and mastering plays an increasingly important role in the experimental teaching of college and technical secondary education.
