Drawing force testing device of open ceramic ring

The invention relates to a drawing force testing device of an open ceramic ring. The drawing force testing device includes an electronic tension meter, a fixed ceramic inserting core and a moving ceramic inserting core, wherein the fixed ceramic inserting core and the moving ceramic inserting core are connected with the open ceramic ring to be tested, and the fixed ceramic inserting core is fixedly arranged at the load bearing end of the tension meter. According to the drawing force testing device, the fixed ceramic inserting core and the moving ceramic inserting core are connected with the open ceramic ring, a cylindrical handheld is drawn to simulate the drawing force test of the open ceramic ring, the drawing force is displayed on the electronic tension meter fixedly connected with the fixed ceramic inserting core, so accurate drawing force is obtained an inaccuracy caused by manual estimation is avoided. The drawing part is simulated practically through the cylindrical middle connection part so accuracy of drawing force testing is improved. The drawing force testing device is simple in structure, convenient to use and accurate in measurement; achieves automatic measurement by being provided with a servo motor, thus further improving measurement accuracy and reducing measurement cost.
