Robot arm flexibility detection device

Abstract

The invention discloses a robot arm flexibility detection device. The device comprises two groups of radial sliding rails which are symmetrically arranged on the left side and the right side, and sliding rail ends are inserted into the front end and the rear end of each radial sliding rail respectively; each sliding rail end is provided with a buffer block towards the center of the radial slidingrail wall surface; a radial connecting block is arranged in each radial sliding rail, and two groups of radial rollers are symmetrically arranged in front of the lower surface of the radial connectingblock; a radial connecting block is installed on each radial roller, and two groups of transverse connecting rails are arranged symmetrically on the opposite wall surfaces of the left and right sidesof the radial rollers; a transverse sliding block is installed on each transverse connecting rail, and two groups of transverse pulleys are symmetrically mounted on the left side and the right side of the lower surface of each transverse connecting rail; and two groups of annular rails are symmetrically mounted on the left side and the right side of each transverse sliding block, and fixed flanges are arranged at the upper ends of the annular rails, wherein two groups of circular track pulleys are installed in the annular rails.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a device for detecting the flexibility of a robot arm. Background technique [0002] An industrial robot is a multi-joint manipulator or a multi-degree-of-freedom machine device for the industrial field. It can perform work automatically and is a machine that realizes various functions by its own power and control capabilities. It can be commanded by humans or run according to pre-programmed programs. Modern industrial robots can also act according to the principles and programs formulated by artificial intelligence technology. Industrial robots are composed of three basic parts: main body, drive system and control system. The main body is the base and the actuator, including the arm, wrist and hand, and some robots also have a walking mechanism. Most industrial robots have 3 to 6 degrees of freedom of motion, of which the wrist usually has 1 to 3 degrees of freedom...

AI Technical Summary

Problems solved by technology

[0003] The existing robot manipulator can add a position sensor at the end of the arm, draw the movement path of the manipulator through the position coordinates sensed and mapped by the position sensor when moving the manipulator, and measure the movement time of the manipulator at the same time to calculate the flexibility of the manipulator arm. It is difficult to measure the maximum flexibility of the robot arm due to the resistance generated by the drive system when the robot arm moves
