The high-strength optical axis fixes the upper beam and the work surface to form a high-rigidity portal frame host:
The transmission structure of the servo motor + reducer + synchronous belt + pulley + precision gapless ball screw realizes the up and down movement of the beam, and the test process is realized through the measurement and control software:
High-precision spoke/S-type force sensor, force measurement accuracy 0.5 level;
A variety of perfect test fixtures, pin connection + simple nut locking, easy to operate;
Add extensometer, displacement meter, large deformation measuring instrument to accurately measure material deformation data;
Powerful full-digital closed-loop, multi-channel measurement and control system, built-in various detection method standards, automatic control of the test process, data can be saved and exported, and can be connected to multiple networked companies;
The bottom of the host is designed with a wheel/adjustable leveling foot to facilitate the equipment placement and later adjustment;
Modular electrical control box for easy troubleshooting;
Test force overload protection, safety limit protection, overcurrent and overvoltage protection, indicator light operation status prompt, voice operation prompt, and design emergency stop switch;
