Abstract

The invention relates to a testbed for the reliability of a power unit of an industrial robot and belongs to reliability testing devices. The testbed is composed of a tris-comprehensive test box, the power unit, a radial force loading unit, a universal joint coupler and a torque loading unit. The power unit and the radial force loading unit are placed in the tris-comprehensive test box, and the torque loading unit is connected with the power unit through the universal joint coupler. The actual working condition of the power unit of the industrial robot can be simulated for reliability testing, the power unit is located in the tris-comprehensive test box, applying of loads such as the temperature, humidity and vibration of the power unit can be achieved, therefore, the actual environment working condition of the power unit of the industrial robot is simulated, higher testing efficiency is achieved, the automation degree is high, vibration, temperature, transmission efficiency, power losses and other parameters of the power unit can be acquired and calculated in real time, and the testbed can be used for detection of transmission errors, return differences and backlashes of a speed reducer.

Description

technical field [0001] The invention belongs to a reliability test device, in particular to a test device applied in the field of reliability of industrial robot power units. Background technique [0002] The power unit of an industrial robot is mainly composed of a servo motor and a reducer, and its cost accounts for more than 65% of the cost of the whole machine. As the core component of the robot, its precision and reliability are crucial. However, the power units of domestic industrial robots mainly rely on imports, and the power units of self-produced industrial robots are immature and have low reliability. 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, st...
