Problems solved by technology

For large-load manipulators, the most important thing is to reduce energy consumption as much as possible. The mechanical efficiency of the worm gear mechanism is very low, and it is not suitable for large-load mechanical work; the rack-and-pinion mechanism occupies a large space and is inconvenient to operate; the wedge The pneumatic chuck can greatly reduce the torque required for pitching, and the control is relatively simple, but the application space is small and the direction change is limited

Description

Technical field: [0001] The invention relates to a magnetic fluid modular mechanical gripper and a working method. Background technique: [0002] Magnetic fluid is a colloidal dispersion system composed of base liquid and granular magnetic solid; the base liquid is the dispersion medium, generally kerosene and mechanical oil, etc., and the solid magnetic particles as the dispersed phase are usually ferromagnetic substances, such as iron , drill, nickel and their magnetic oxides, etc. Ferrofluids have colloidal stability and component stability, as well as good magnetization properties. When no external magnetic field is applied, the smaller the viscosity of the rheological fluid (≤1.0Pa·s), the better the magnetorheological effect of the rheological fluid. The viscosity of the magnetic fluid has a significant change after the magnetization, and the response is fast. At present, the saturation magnetization of ferrofluid with magnetite as solid particles can reach up to ab...
