Compressive testing bed for testing fatigue, durability and parameters of valve mechanism

The invention relates to a comprehensive testing bed for testing fatigue, durability and parameters of a valve mechanism. The comprehensive testing bed comprises a data collecting and controlling device, a driving device, a lubricating system and a mechanical rack arranged on a base. The mechanical rack comprises a sample installation seat and a driving device installation seat. The driving device is fixedly installed on the driving device installation seat. The sample installation seat is used for holding a test object. One end of the test object is connected with the driving end of the driving device through a transmission assembly, and the other end of the test object is connected with the lubricating system. The data collecting and controlling device is electrically connected with the driving device, the lubricating system, the mechanical rack and the test object. In this way, if a part manufacturer conducts testing through the comprehensive testing bed, the testing period will be shortened, cost will be greatly reduced, risk will be lowered, the development time of the product is shortened, and development cost is lowered.
