Abstract
The utility model relates to an electric dynamic and static testing machine and belongs to the field of testing machines. A linear motor is fixedly connected with the upper beam through a bolt. The upper beam is sleeved on an upright. A rotor of the linear motor penetrates through the upper beam and is fixedly connected with a cardan joint. The lower end of the cardan joint is fixedly connected with an upper tensile fixture pair. A force sensor is fixedly connected with a base through a bolt. The upper end of the force sensor is fixedly connected with the lower tensile fixture pair. The lower end of a screw rod is fixedly connected with the base and the upper end of the screw rod is fixedly connected with the upper end of the upright through a connecting piece. The screw rod is connected with the upper beam through two sets of worm wheel worms. Worms of the worm wheel worms are connected with the upper beam in a rotary mode through a locating bearing and are fixedly connected with a shaft of a drive motor through a coupling. A drag chain is respectively connected with the base and the upper beam. The electric dynamic and static testing machine has the advantages of being novel in structure, capable of achieving precise displacement and small load control and achieving space adjustment conveniently, precise in measurement, accurate in control and simple in operation.
