Three-way Vibration Testing Machine Based on Cam Mechanism

Abstract

The invention relates to the technical field of mechanical devices and particularly relates to a vibration testing machine. Disclosed is a three-direction-vibration testing machine based on a cam mechanism. The three-direction-vibration testing machine includes an engine base, an adjustable-speed motor, a box body, a main vibration platform and a driving mechanism. The driving mechanism includes a cam mechanism, a driven guide rod A, a linear bearing and a driven guide rod B. The cam mechanism includes a cylindrical cam and a cam track groove. A transmission shaft of the cylindrical cam is connected with the adjustable-speed motor. One end of the driven guide rod A is arranged in the cam track groove and the other end is connected fixedly with a slide block of the linear bearing. One end of the driven guide B is connected with the slide block of the linear bearing and the other end is connected with an auxiliary vibration platform. A guide groove is arranged in the main vibration platform and the guide groove is arranged obliquely for 45 degrees in a motion direction. An X-direction guide rod is fixed on the auxiliary vibration platform. The X-direction guide rod slides relatively in the guide groove. Because the cam mechanism, which takes machinery as the main body, is used in the three-direction-vibration testing machine, operation and control are simple and interferences are not caused on a corresponding testing system.
