Abstract
The invention relates to a load controllable active type follow-up force-applying linear guide rail pair test bed. Force-applying heads (force-applying points) of a transverse loading mechanism and a vertical loading mechanism independently use or share a lead screw driving mechanism so that the transverse loading mechanism and the vertical loading mechanism move synchronously along with a stressed sliding table and the force-applying points are relatively stationary with four guide rail sliding blocks. Therefore, loads applied by a force-applying device can be uniformly and invariably acted on the four guide rail sliding blocks. The load born by each guide rail sliding block is 1/4 of that applied by the fore-applying device, namely, change curves of the loads born by the guide rail sliding blocks are completely consistent with the change curves of force applied by the force-applying device, only the amplitude is reduced to 1/4. Therefore, when the load controllable active type follow-up force-applying linear guide rail pair test bed is used for carrying out a performance and service life test on the linear guide rail pair, the load applied can be conveniently, precisely and reliably controlled so as to relatively accurately and reliably evaluate a relationship among the load, the performance and service life of the linear guide rail pair, thus providing a relatively reliable test basis for design and maintenance of the guide rail pair.
