A hardness tester with a multi-directional positioning structure

Abstract

This utility model discloses a hardness tester with a multi-directional positioning structure, relating to the field of hardness testers. It includes a base with a pressure button connected to its side. A lifting seat is mounted on the upper inner surface of the base, and a clamping platform is connected to a lifting rod at the top of the lifting seat. The rotating mechanism includes a worm gear meshing with the side of a worm wheel, the worm gear rotating through a rotating groove, a threaded rod rotating through the rotating groove, and an insert block fixed directly below the connecting platform. The insert block and the insert rod are slidably connected through the groove. In this hardness tester with a multi-directional positioning structure, during measurement, the test piece is fixed on the clamping platform. When other positions need to be measured, rotating the worm gear drives the worm wheel and gear cylinder to rotate, causing the threaded rod to slide, pushing the fixed block upwards, and adjusting the tilt angle of the clamping platform. The bottom of the platform rotates via three fixed blocks, and the three sets of worm gears allow for multi-directional measurement, improving ease of use.
