The host adopts a portal structure, with servo motors and reducers located at the lower part of the host. All tests are conducted between the middle crossbeam and upper crossbeam, as well as between the middle crossbeam and the worktable. This machine has a dual space structure of upward and downward compression. The space between the middle crossbeam and the workbench is for compression and bending tests, and the space between the middle crossbeam and the upper crossbeam is for tensile tests; The servo motor drives the precision ball screw pair to rotate through the pulley reducer, thereby driving the middle crossbeam to move up and down and load the sample. The size of the test speed is controlled by the motor speed control system installed under the host.After replacing the column, screw, and outer cover, the test space can be changed. The transmission system consists of a servo controlled dedicated reducer, a circular arc synchronous toothed belt, and a ball screw pair, which runs smoothly, has high efficiency, and low noise. pollution-free.
