AI Technical Summary

Technical Problem

The modular fixtures of traditional universal testing machines are time-consuming to change, making it difficult to meet the needs of high-frequency testing. Furthermore, repeated disassembly and assembly can easily cause interface wear and sample clamping misalignment, affecting test repeatability and safety.

Method used

It adopts an innovative quick-release clamping mechanism and active protection system, which realizes tool-free quick change of modular clamps and full-domain safety protection during the testing process through mechanical self-locking and physical barriers, including the integrated design of mechanical self-locking and physical barriers.

Benefits of technology

It significantly improves equipment operating efficiency and testing reliability, ensures accurate positioning and efficient replacement of modular fixtures, enhances the safety of the testing process, and avoids impact injuries to operators from high-speed debris.

Abstract

This utility model relates to the field of universal testing machine technology, and discloses a universal testing machine for coated steel strips, including a base. A worktable is fixedly connected to the upper surface of the base, and a column is fixedly connected to the upper surface of the worktable. A movable crossbeam is slidably connected inside the column, and an installation sleeve is fixedly connected to the lower surface of the movable crossbeam. A connecting sleeve is slidably connected inside the installation sleeve, and a fixing component is provided inside the connecting sleeve. The fixing component includes a fixing bead, which is disposed inside the connecting sleeve, and a compression bead is slidably connected to the outer wall of the fixing bead. In this utility model, by inserting the connecting sleeve into the installation sleeve, the fixing bead is radially compressed, pushing the compression bead to drive the push plate to compress the spring. The spring returns to its original position, driving the compression bead to push the fixing bead into the limiting groove of the installation sleeve to form a lock, thereby achieving precise positioning and efficient replacement of the modular fixture.
