The invention discloses a device for testing motion accuracy of robots. The device comprises a linear accuracy testing mechanism and a repetitive positioning accuracy testing mechanism, wherein the linear accuracy testing mechanism comprises a standard bar supporting base, a standard bar, a screw jack, a counterweight block, a connection flange, a connection block, a counterweight block mounting bracket, a test rod, a sensor mounting bracket and a laser sensor probe, wherein the repetitive positioning accuracy testing mechanism comprises a sensor supporting base, a magnetic bracket, a sensor bracket and a laser sensor probe. The device is suitable for testing the motion accuracy of different specifications of robots; by virtue of a manner of additionally arranging the counterweight block on the front end arm of the robot, the motion state of the robot is closer to the actual working condition; the whole testing device is simple in structure, convenient to operate and suitable for testing the accuracy of large quantities of robots.
Description
technical field [0001] The invention relates to a precision testing device, in particular to a robot movement precision testing device. Background technique [0002] With the development of domestic industrial automation, industrial robots are widely used as an important means of realization, such as painting robots, handling robots, welding robots, etc. The application fields of robots are constantly expanding, and the requirements for the position accuracy of industrial robots are getting higher and higher. This requires a corresponding precision testing device with high precision, easy operation and simple structure to adapt to it, in order to make an objective evaluation of it. [0003] At this stage, there are many factors that affect the accuracy of the robot, and there are many testing methods. At present, the two most critical accuracy indicators in the use of robots are repeat positioning accuracy and linear accuracy; although the current test device can achieve t...
