Rebound value testing device

Abstract

A rebound value testing device comprises a rebound instrument and a clamp, wherein the rebound instrument and the clamp are located at the front end and the rear end of a framework respectively and are oppositely arranged, connecting rods connected with an upper framework beam and a lower framework beam are arranged on the left side and right side of the front end of the framework respectively, a rebound instrument fixing frame is arranged between the two connecting rods at the front end of the framework, and connecting rods connected with the upper framework beam and the lower framework beam are arranged on the left side and right side of the rear end of the framework respectively; the clamp comprises a fixed plate fixed to the left connecting rod at the rear end of the framework, and a movable plate located between the fixed plate and the right connecting rod at the rear end of the framework, a laterally-through threaded hole is formed in the right connecting rod at the rear end of the framework, a threaded lead screw penetrating through the threaded hole is also arranged on the right connecting rod at the rear end of the framework, a protruding cavity is formed in the right side of the movable plate, a rotary body capable of rotating in the cavity is arranged in the cavity, and the left end of the threaded lead screw penetrates through an opening in the cavity to be fixedly connected with the rotary body. The device applies pressure onto a ceramic tile evenly and is suitable for fixing ceramic tiles or other flaky materials in different sizes.

Description

technical field [0001] The invention relates to a rebound value testing device. Background technique [0002] When ceramic tiles are directly tested for rebound value, ceramic tiles will vibrate or move, resulting in the inability to complete the rebound value test or inaccurate test data. The main factors mainly include: ceramic tiles will be affected by Vibration or displacement occurs due to impact, and the width of the side of the ceramic tile is narrow, so it is difficult to ensure that the rebound hammer is completely perpendicular to the measured surface. Therefore, how to stably fix ceramic tiles of different sizes is the key to completing the test of the rebound value of ceramic tiles. Contents of the invention [0003] The object of the present invention is to provide a rebound value test device, which can apply uniform pressure to each point of the ceramic tile, and can be applied to fix ceramic tiles or other sheet materials of different sizes, so that the reb...
