Modular flexible connection device allowing dynamic adjustment of stiffness

Abstract

The invention discloses a modular flexible connection device allowing dynamic adjustment of the stiffness and belongs to the mechanical design technical filed. An upper top plate is fixed on an installing ring, a bearing installing frame is fixed on a lower base plate through a connecting column, and accordingly the upper top plate and the lower base plate can only rotate relative to each other to maintain the mutual distance to be fixed and accordingly the required stable connection function is achieved. The stiffness variable function is achieved through the change of the relative position of a sliding block and the tail end of a spring piece. When a wire rolling shaft rotates, the reciprocating motion of the sliding block can be ensured along with the extension and retraction of two steel wires and accordingly the relative position of the sliding block and the tail end of the spring piece can be changed. According to the modular flexible connection device allowing the dynamic adjustment of the stiffness, the stable connection and stiffness variable functions are integrated into a whole and accordingly the modular production and utilization is convenient and the industrial application and popularization is convenient and the structural design is compact, the size is small, and accordingly the installation requirements under the condition that the size is limited can be met.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, and relates to a mechanical connection device between two modules, in particular to a device capable of realizing a stable connection between two modules and an adjustable connection stiffness. The device adopts a modular design idea and integrates the two functions of stable connection and variable stiffness. Background technique [0002] In the traditional industrial manufacturing process, the external environment is known, and the robot relies on precise position control, moves according to the pre-planned route, and completes monotonous and repetitive work. For this kind of industrial robot, the focus is on the control of precise point motion, so rigid connections are often used between various parts of industrial robots. However, even precise positional control is not enough when the robot end effector comes into contact with the surrounding environment. If contact force control ...
