Abstract
The present invention mainly provides an automatic testing system for vibration and noise of electric hand drill, including a holding unit, a noise isolation chamber, a signal testing unit and a data processing unit, in which the holding unit has a robotic arm holding an electric drill on a conveyor and placing it in the noise isolation chamber and further placing it back on the conveyor after finishing test thereof, a sound-absorbing material is stuck on the inner surface of the noise isolation chamber to form an open and gigantic spatial sound field; the signal testing unit is disposed inside the noise isolation chamber so as to perform rotation speed and noise tests simultaneously and transmit the testing signal through a digital interface circuit to the data processing unit, and the data processing unit is built in the standard deviation of rotation speeds of the electric drill and the noise power values so as to carry out real-time analysis and processing on the obtained rotation speeds of the electric drill and the noise data and inspect if the electric drill will pass a quality inspection standard.
