Abstract
A motor vibration life testing device comprises a mounting rack which is provided with a positioning groove used for placing a motor to be tested; the positioning piece is used for pressing the to-be-tested motor in the positioning groove from top to bottom; one end of each conductive thimble along the length direction is provided with an elastic part, the elastic parts at one ends of the conductive thimbles are pressed and are respectively contacted with positive and negative elastic sheets of the to-be-tested motor, and the other ends of the conductive thimbles are respectively connected with a lead; the relay module is provided with an input end and an output end, the input end is used for being connected with a direct-current power supply, and the two wires are electrically connected to the output end and used for supplying power to the to-be-tested motor, so that the direct current controls the to-be-tested motor to continuously or discontinuously vibrate through the relay module. The positive electrode and the negative electrode of the to-be-tested motor are elastically contacted and led out through the two conductive ejector pins, so that the motor is prevented from being damaged by high temperature generated by direct welding on the motor and the condition that elastic sheets of the positive electrode and the negative electrode fall off is avoided, and the problems of loosening and failure caused by welding wiring, high temperature and vibration of the motor are solved.
