Problems solved by technology

[0003] However, the use of a single-degree-of-freedom active contact flange cannot completely solve the problems existing in the related processing process. Due to the constant output force direction of the above-mentioned device and the low positioning accuracy of the robot pose, it is impossible to perfor

Abstract

The invention discloses a space three-degree-of-freedom parallel mild operation device and a mild mode thereof. The space three-degree-of-freedom parallel mild operation device comprises a mechanical interface, a tool connecting bracket, at least three sets of motion branched chains connected between the mechanical interface and the bracket, and a controller; and the controller controls force output by the operation device.

Description

technical field [0001] The patent of the present invention relates to the robot's constrained operation process, and in particular to a space three-degree-of-freedom parallel compliant operation device and its compliant method. Background technique [0002] For robots with constrained operation processes, such as grinding, polishing, scrubbing, assembly, handling, etc., it is necessary to control the force of the tool acting on the surface of the workpiece during the process. Using robots to control positioning and tool force is generally not suitable for many applications. accurate. Take grinding and handling as an example to illustrate the significance of using a compliant device for a robot: During the grinding process of a robot, due to the low absolute positioning accuracy of the end of the robot, the running trajectory generally cannot be an accurate straight line or arc, and even has a few mm of trajectory error, so The active compliance device can realize active pow...
