Industrial robot speed reducer torsion rigidity testing stand

Abstract

The invention relates to the technical field of an industrial robot speed reducer and particularly relates to an industrial robot speed reducer torsion rigidity testing stand. A vertical board is mounted at an upper side end of a supporting stand, a driving motor, a speed reducer, a torsion sensor and an electric dynamometer are sequentially mounted on the vertical board from up to down, a center rotation shaft of the driving motor is connected with the speed reducer, the speed reducer is connected with the torsion sensor through a shaft coupling, the torsion sensor is connected with the electric dynamometer through the shaft coupling, the torsion sensor is connected with a circular grating through a program control wire, and the torsion sensor, the driving motor and the electric dynamometer are connected with a controller through program control wires. The industrial robot speed reducer torsion rigidity testing stand is advantaged in that torsion loading for a power unit is carried out through the electric dynamometer, magnitude of an application torque can be automatically adjusted, a radial force loading unit is employed to simulate a radial force of the power unit of the industrial robot in a start or operation process, and magnitude of applied radial force can be automatically adjusted.

Description

technical field [0001] The invention relates to the technical field of industrial robot reducers, in particular to an industrial robot reducer torsional rigidity test bench. Background technique [0002] The servo motor of the industrial robot power unit has the characteristics of small inertia, fast response speed, and low maintenance and maintenance requirements; the reducer of the industrial robot power unit is one of the key technologies of industrial robots, with high transmission stiffness, large transmission ratio, and small inertia. , large output torque, stable transmission, small size, strong impact resistance, etc. [0003] The power unit of the industrial robot is installed in the narrow space inside the joint arm of the industrial robot, which has slow heat dissipation, easy vibration, harsh working environment, and prone to failure. The industrial robot power unit reliability test bench can simulate its actual working conditions and conduct reliability tests, ...

AI Technical Summary

Problems solved by technology

[0006] (1) The test benches are scattered. If you want to perform all measurements on the same precision reducer, you need to replace multiple test benches, which is cumbersome and time-consuming;

[0007] (2) A single test bench is large in size and takes up too much space;

[0008] (3) Due to the single function of each test bench, it is necessary to purchase a variety of test benches to meet all measurement requirements, and the procurement cost is relatively high
