Abstract

A flexible clamp based on magneto-rheological plaster comprises a clamp base. The clamp base is provided with a fixed clamping body and a movable clamping body. The fixed clamping body and the movable clamping body are respectively provided with an iron core, the two iron cores are located on the same axis line, the iron cores are wound by magnet exciting coils respectively, the magnet exciting coils are respectively connected with a direct current power source through wires, the opposite ends of the two iron cores respectively fix a clamping plate, the clamping planes of the two clamping plates are provided with grooves oppositely corresponding to each other, the two grooves are respectively filled with magneto-rheological plaster, and openings of the grooves are respectively sealed through a rubber sheet. The flexible clamp is fast in response, easy to control, good in stability and high in reliability.

Description

technical field [0001] The invention relates to the field of clamps, in particular to a flexible clamp based on magnetorheological cement. Background technique [0002] Since the 1970s, with the widespread use of NC machine tools and machining centers in production, flexibility has become one of the main development directions of modern manufacturing. Continued use of special fixtures will limit the manufacturing system to achieve true flexibility, and flexible fixtures came into being. pregnancy. The currently used flexible fixtures mainly include: phase change and pseudo phase change material flexible fixtures, modular program control fixtures, bionic gripper fixtures, adjustable fixtures, group fixtures and combined fixtures, etc. The above-mentioned fixtures are too complex in structure, high in cost, and limited in flexibility, so they are not easy to be popularized in production, and they are far from meeting the standards of engineering applications, and many problem...
