Composition of computer-controlled wheel indoor weighted fatigue testing machine equipment
The experimental equipment consists of a main unit and a control cabinet. The main unit adopts a small gantry platform structure, and the loading rack moves in space. From the diagram, it can be seen that the main engine consists of three main parts: the base platform, the mobile loading frame, and the reciprocating power mechanism. Linear guide rails are installed on both sides of the base, and the mobile loading frame is mounted on four sliders through pillar fixed seats. One side of the left and right pillar fixing seats is connected by a connector. The reciprocating electric cylinder piston rod is connected to the connecting piece, which can drive the entire loading mechanism to move back and forth
The mobile loading rack consists of upper fixed top plate, two pillars, mobile crossbeam, pillar fixed seat, loading linear electric cylinder, load sensor and other components. The fixed top plate forms a square frame with two pillars and pillar fixing seats. The loading electric cylinder is installed between the fixed top plate and the moving crossbeam. The expansion and contraction of the electric cylinder can drive the moving crossbeam to move up and down along the pillars through a sliding guide sleeve.
Install loading wheels on the lower surface of the moving crossbeam, and move the moving crossbeam along the column through the telescopic traction of the electric cylinder. Create a compressive load between the loading wheel and the specimen.
The whole machine has a simple structure, high integration, high strength, and small deformation
