The invention discloses an apparatus for the real-time automatic measurement of folding angles. The apparatus comprises a pedestal, a left measuring plate, a right measuring plate, a measuring plate support and a sensing device; the measuring plate support is fixedly connected to the pedestal, and the sensing device is rotationally connected to the pedestal; the left measuring plate and the right measuring plate are respectively rotationally connected to the measuring plate, the upper surface of the left measuring plate is flush with the upper surface of the right measuring plate, and a groove is arranged on the measuring plate support and just below the abutting end of the left and right measuring plates; and the left measuring plate is provided with a first gear, the right measuring plate is provided with a second gear, and the sensing device is provided with a third gear engaged with the first gear and a fourth gear engaged with the second gear. The apparatus for the real-time automatic measurement of folding angles adopts a high-precision gear mechanism to realize accurate transmission, and simultaneously transmits the folding angles of two sides of a folded piece to an angle feedback element, so the folding angles of the whole piece are directly and accurately obtained. The apparatus has the advantages of simple structure, use convenience and easy realization.
Description
technical field [0001] The invention relates to a device for automatically measuring the bending angle in real time. Background technique [0002] Bending machine is a kind of equipment used to bend sheet materials, as shown in the attached manual figure 1 As shown, the bending principle is to place the workpiece on the plane of the lower mold. When the upper mold presses the lower mold, the workpiece forms a bending angle under the action of the pressure and the upper and lower molds. When bending workpieces (such as sheet metal parts), how to accurately control the bending angle of the workpiece is a problem that both bending machine manufacturers and application companies are more concerned about. At present, there are many methods for measuring the bending angle of bending machines, and some of these methods have solved the problem that the upper and lower dies cannot be aligned accurately; some methods use the flexible transmission of steel wires and require the torsio...
