Abstract

The invention relates to a measurement device for the tail spatial position of a robot. The measurement device comprises a base, a stay wire encoder, a transitional mounting plate, encoder assemblies, synchronous belts and follow-up pointing mechanisms, wherein the stay wire encoder is mounted on the bottom of the base through screws; the transitional mounting plate is mounted on the top of the base through screws; the two encoder assemblies are mounted in the middle of the base through screws; and the follow-up pointing mechanisms are mounted in four round holes of the transitional mounting plate through deep groove ball bearings and connected with the encoder assemblies through the synchronous belts. The measurement device is high in precision, convenient to operate and low in cost, and has a low requirement for the measurement environment.

Description

Technical field [0001] The invention discloses a device for measuring the space position of the end of a robot, and relates to the field of measuring the end position of the robot. Background technique [0002] The robot terminal space position measuring device is used for the calibration of the positioning accuracy of the robot when it leaves the factory, and the detection of the speed and acceleration during the movement. After measuring the end position, speed and acceleration, and calibrating the robot, the positioning accuracy of the robot can be greatly improved, and the working efficiency of the robot can be improved. [0003] At present, the space position of the robot end generally includes theodolite, three-coordinate measuring instrument, visual inspection technology, and laser tracking technology. However, the use of theodolite is complicated and cumbersome. The three-coordinate measuring instrument has strict requirements for the measurement environment and is not suit...
