The NJW-100 multifunctional bolt simulation assembly testing machine is mainly used for laboratory bolt assembly simulation tests, obtaining torque and angle relationship curves for different assembly methods, and further analyzing the rationality of assembly processes. In addition, the testing machine can also perform assembly tests on ultra short bolts, screwing in and out tests on glued bolts, and screwing in and out tests on anti loosening nuts.
This series of testing machines is a customized specialized machine, mainly composed of a host, bolt tightening system, tooling, control unit, and software. Meet some testing requirements of standards such as GB/T3098.1-2010, GB/T3098.9-2010, GB/T16823.2-2010, GB/T16823.3-2010, ISO16047-2008, etc. After setting the assembly process, use a bolt tightening machine to apply assembly torque to the tested bolts according to the set parameters, so as to achieve a tight connection of the connected parts.
This test machine can simultaneously measure total torque and angle, draw the relationship curve between total torque, angle, and measurement time, and obtain the assembly torque and angle, measurement time, and other values at any point in the graph. It can automatically record various test results and characteristic curves.
The testing machine has two basic configurations: first, the bolt tightening machine (Atlas Sweden or DDK Japan) consistent with the main engine factory is used for stable and accurate loading, stable without creeping, fast no-load adjustment, high speed and low noise. The measurement and control system adopts the TC-4000-P-ES controller equipped with the tightening machine, and uses DDK software; The second is to use Yaskawa servo motors from Japan, Pinhong servo planetary reducers from Taiwan, and the drag system developed by Bairuo, combined with the first comprehensive modular TestLive computer testing software in China, to ensure the stable operation, accurate measurement, and reliable testing of the entire system.
