Claim 0:
1. A high-throughput and small size samples tension, compression, bending test system comprising a computer unit, a motor (1) and a plurality of sample testing modules (2) provided on a workbench (3) horizontally or vertically to the ground;
wherein the sample testing modules (2) comprises sample testing modules base plates (39) secured to the workbench (3), a ball screw (16), a displacement sensor (17), a moving beam (18), a clamp unit (19), a linear moving platform unit (23) and a force value sensor (24) provided on the sample testing modules base plates (39); the ball screw (16) and the linear moving platform unit (23) are respectively provided at both ends of the clamp unit (19);
an inner end of the ball screw (16) is fixed to transmission devices, and the ball screw and the moving beam (18) is driven synchronously along the linear guide rail; the displacement sensor (17) is installed on the side surface of a linear guide rail fixing base (30) for detecting the movement displacement of the moving beam (18) in real time;
the linear moving platform unit (23) comprises a trapezoidal screw/lead screw (42) and a linear moving platform guide rail (29), the trapezoidal screw/lead screw (42) slides controllably along the linear moving platform guide rail (29), the force value sensor (24) is fixed on a trapezoidal screw/lead screw pair fixing base (28) through a force value sensor fixing base (25);
an outer end surface of the moving beam (18) is fixedly connected with a first clamp connecting rod (38); the force value sensor (24) is fixedly connected with a second clamp connecting rod (41); two holding portions of the clamp unit (19) for holding a sample (22) are secured to the first clamp connecting rod (38) and the second clamp connecting rod (41) respectively;
a plurality of the sample testing modules (2) are arranged in parallel on the workbench (3), or a plurality of the sample testing modules (2) are uniformly provided in a circumferential direction with a point on the workbench (3) being the center; the ball screw (16) of each sample testing modules (2) faces the center of the circle; the motor (1) drives the ball screw (16) of each of the sample testing modules (2) to rotate synchronously through the transmission devices, realizing a synchronous back and forth movement of the moving beam (18) of each of the sample testing modules (2), and further realizing the synchronous tension, compression, bending and other tests of the sample (22);
the computer unit is respectively connected to the motor (1), the displacement sensor (17), the force value sensor (24), a physical field unit (20) and a visual observation unit (21); the computer unit is configured to independently collect the test data of the displacement sensor (17) and the force value sensor (24) of each of the sample testing modules (2), and calculate and plot the respective measurement parameters and test curves.
