Abstract

The invention provides a magnetorheological-elastomer-based parallel power control device which can form controllable vector pressure in one direction at the tail end of an industrial robot or a machine tool spindle so as to control polishing pressure applied on the surface of a part more accurately and enable surface quality of the polished part to be improved substantially. The magnetorheological-elastomer-based parallel power control device comprises an upper connecting plate and a lower connecting plate. The magnetorheological-elastomer-based parallel power control device is characterized in that four shearing-type pressure control mechanisms are all arranged in a middle cavity between the upper connecting plate and the lower connecting plate, each shearing-type pressure control mechanism is correspondingly connected with outer-side portions of corresponding round faces of the upper connecting plate and the lower connecting plate and comprises an upper support, a shearing block, a lower support and an electromagnet, each upper support is connected with the upper connecting plate through a rotating hinge, and each lower support is connected with the lower connecting plate through a ball hinge.

Description

technical field [0001] The invention relates to the technical field of vector force control in mechanical manufacturing, in particular to a parallel force control device based on magneto-rheological elastomers. Background technique [0002] Polishing is a common manufacturing process in the field of mechanical product manufacturing. During the polishing process, it is not only necessary to ensure that the polishing head moves along a certain path, but also to ensure that the pressure vector between the polishing head and the surface of the polished part Keep relatively constant, so it puts forward high requirements for the control technology of automatic polishing equipment. Based on the above reasons, in the field of actual production, the polishing of many parts, especially the polishing of molds, is still done manually. However, there are dust and noise pollution in manual polishing, which has a huge adverse effect on the health of workers. Therefore, it is necessary to...
