Flexible flange for robot and robot

Abstract

The present invention proposes a flexible flange for a robot and the robot, comprising: a shell with an input port for inputting gas or liquid with a set pressure; a piston set fixed inside the shell and located at one end of the shell; There is a pressure channel between it and the input interface; the piston is set in the piston kit and can reciprocate in it. When the pressure channel is fed with gas or liquid, the piston can be pushed forward by the pressure of gas or liquid; the actuator connection method The blue is movably arranged at the other end of the housing, and one end protrudes from the housing, and the other end is supported by the piston, so that it can float in the housing according to the gas or liquid pressure and external force; it also includes a restricting part to limit the execution The connecting flange of the device rotates around its axis. The flexible flange of the present invention can move with multiple degrees of freedom, which solves the problem of collision damage to the workpiece caused by the inability of the robot to move flexibly or the delay of signal feedback during the assembly and processing process.

Description

technical field [0001] The invention relates to the field of robots, in particular to a transition connection device between a robot and an actuator. Background technique [0002] At present, the application of industrial robots is becoming more and more common, and the scope of application is becoming wider and wider. Due to its own structure, articulated industrial robots have relatively high repeatability and low positioning accuracy, which limits the application of industrial robots in the field of assembly and processing. [0003] The existing solution is to use a high-precision six-dimensional force sensor as a transitional connection between the robot and the actuator. The six-dimensional force sensor can measure the force in the three directions of x, y, and z and the torque around the three axes. The force and torque signals obtained by the sensor are fed back to the robot's control system, so that the robot can respond accordingly. However, this method has the fo...
