Abstract

The invention relates to a test bed for detecting the performance of an automobile steering column adjusting mechanism, in particular to a test bed capable of realizing high-automation control, and belongs to the field of automobile technology research, development and test. The test bed can realize driving of any spatial position required by an automobile steering column adjusting mechanism, andrealizes actual measurement of force and motion speed in two directions in space. The test bed comprises a rack assembly, a three-axis adjusting shaft assembly, a clamping force measuring assembly, apneumatic assembly, a clamping system assembly, a hydraulic system assembly, a clamp module and the like. Through mutual cooperation of the components, the impact load resistance of the sample piececan be conveniently detected, and the detection effect is more accurate.
