The utility model discloses an industrial robot one -dimensional movement track testing arrangement, the device includes linear displacement sensor and oscilloscope, linear displacement sensor one end is connected with the robot's work end through flexible coupling assembling, linear displacement sensor's signal output part and oscilloscope's signal input part are connected, under the test state, motion along with the robot work end, linear displacement sensor transmits the voltage signal who records for oscilloscope, oscilloscope takes notes and shows the one -dimensional movement track of the robot work end. Because the utility model provides a testing arrangement is that the linear displacement sensor through the high accuracy transmits the the robot one -dimensional movement track's that records voltage signal and takes notes and show for oscilloscope, therefore resetting that not only can the motion in one dimension of accurate realization robot, improves measurement accuracy, and can also visual display goes out the one -dimensional movement track of robot, the movement track's of being convenient for in time know current situation.
