2results about How to "High repeatability accuracy" patented technology

This invention discloses a non-rigid connection, fast-drive, high-precision displacement measuring device, comprising a support, a threaded tube, a threaded column, and a measuring anvil. The threaded tube has internal threads that engage with the threaded column's external threads. The support houses a measuring shaft, an elastic element, and a measuring element for measuring the displacement of the measuring shaft. One end of the measuring shaft is a probe, which engages with the measuring anvil. The measuring shaft is connected to the threaded column, which has only axial freedom under the action of a guiding mechanism. The measuring shaft is connected to the support via a linear guide rail. One end of the elastic element is connected to the support, and the other end is connected to the measuring shaft. The elastic element applies a restoring force to the measuring shaft in the direction of the measured point. This invention employs a non-rigid connection between the measuring shaft and the drive structure. The measuring rod is provided with a constant measuring force only by a spring at the same deformation position, improving repeatability accuracy and preventing excessive external forces from affecting the measuring tool's accuracy and damaging the measured workpiece. The use of rotation and actuation allows for rapid size switching, resulting in high measurement efficiency.
