Abstract

A magnetic rheology polishing solution rheology testing device comprises a computer, a bracket, a torque measuring device fixed on the bracket, a magnetic field generating device, a shearing mechanism and an actuating device, the torque measuring device, the magnetic field generating device and the actuating device are connected with the computer, the shearing mechanism arranged in the magnetic field generating device comprises a shearing ring and a fixed ring, the shearing ring is fixed on the upper side of the fixed ring, the shearing ring and the external circumference on the fixed ring are respectively arranged with a shearing ring edge and a fixed ring edge which have a certain height, a liquid storing groove which is used for storing the magnetic rheology polishing solution is formed between the shearing ring edge and the fixed ring edge, the upper side of the center of the shearing edge which is discal is arranged with a rotation axis connected with the actuating device, and the lower side of the center of the fixed ring is arranged with a connecting axis connected with the torque measuring device. The invention has the advantages of simple and compact structure, low cost, convenient controlling, stable testing, high precision and the like.

Description

technical field [0001] The invention mainly relates to the technical field of magnetorheological polishing, in particular to a device for testing rheological properties of magnetorheological polishing fluid. Background technique [0002] Magnetorheological polishing fluid (Magnetorheological polishing fluid) is composed of carrier liquid (such as water, mineral oil, silicone oil, etc.), magnetic sensitive particles, surfactants, polishing particles and additives with other functions. The rheology of magnetorheological polishing fluid means that it hardens under the action of an external magnetic field and has properties similar to "solid". The greater the strength of the applied magnetic field, the greater the hardness of the magnetorheological polishing fluid. After the magnetic field is removed, the magnetorheological polishing fluid can quickly return to a liquid state. Magnetorheological finishing technology is to use the rheology of magnetorheological polishing fluid i...
