The invention relates to a capacitive double measuring bar butt joint flatness detector, comprising a case and an upper cover arranged at the top of the case; wherein the case is internally symmetrically provided with a left measuring bar and a right measuring bar the heads of which stretch out the base plate of the case, the heads of the left and right measuring bars are respectively provided with a measuring head, the outer sides of the left and right measuring bars in the case are respectively provided with a guide rail fixed on the inner wall of the case, the inner sides of the left and right measuring bars are provided with a capacitance pole plate fixed on an insulation block, the two sides of the insulation block are respectively fixed on the left and right measuring bars, the left and right measuring bars are respectively provided with a slide block moving along with the guide rail, the bottom of the slide block is provided with a spring, the upper end of the case is fixed with a positioning plate which penetrates and fastens the left and right measuring bars, and the upper cover is provided with a signal processor which is connected with a terminal plug and is used for acquiring and processing relative displacement signal of the two measuring bars. Structure is simple, operation is easy, time and manpower are saved, and detection efficiency is high.
Description
technical field [0001] The invention relates to a capacitance-type double-measuring-rod docking flatness detector, which is especially suitable for testing the docking flatness during the docking process of structural parts such as various curved surfaces, planes, and revolving bodies. Background technique [0002] At present, most of the flatness detection of the butt joint adopts the profiling detection method, that is, the worker uses a straight board with a high flatness to compare whether the boards that are joined together are on the same plane. This detection method cannot guarantee accuracy, is labor-intensive, time-consuming and labor-intensive, and is not conducive to automated production. Another method that is used more is to use a measuring tool with a single measuring rod such as a dial indicator to measure the distance between two plates and a fixed measuring device. The operation process of this method is loaded down with trivial details, and efficiency is l...
