APPARATUS FOR SHEAR AND FLEXURAL STRESS TEST

摘要

PURPOSE: An integral shear and bending testing apparatus is provided to obtain the reliability of the test result due to the enhanced precision by mounting a space adjusting lever and a digital micrometer and semi-automatically adjusting the space of the guage mark of a load finely. CONSTITUTION: An integral shear and bending testing apparatus comprises a base(18), a convey rod(15), a space adjusting lever(24), first and second supports(13,14), a digital micrometer(25), a support rod, a pressing plate(40), and a depressor(12). An empty space is formed at the inner side of the base in the longitudinal direction. The convey rod is installed to pass through both ends of the base and a male screw part with an opposite direction is formed at each outer circumference of one side and the other side of the base bisected. The space adjusting lever is coupled to one end of the convey rod. The digital micrometer is formed at the end of the space adjusting lever in order to be able to measure the interval between the first and second supports. The support rod is vertically connected to the edge of the base. The pressing plate is connected to the top of the support rod. The depressor is connected to the bottom of the pressing plate.
