  • Publication number: 20240151514
    Abstract: A conical workpiece length measurement method is provided. Two laser displacement sensors are symmetrically arranged at opposite sides of a to-be-measured conical workpiece or a tooling loaded with the to-be-measured conical workpiece. Distance X0 from each displacement sensor to a bottom plane of the to-be-measured conical workpiece is calibrated. An elongated base plate is arranged at a tip of the to-be-measured conical workpiece, and the two displacement sensors measure their respective distances to the base plate. The total length of the to-be-measured conical workpiece is calculated as follows: X=X0+(X1+X2)/2, where X1 represents distance from one of the two displacement sensors to the base plate, and X2 represents distance from the other of the two displacement sensors to the base plate. Factors influencing the length measurement include calibration of the fixed length, measurement accuracy of the displacement sensor and a tilt error of the base plate.

  • Publication number: 20240151605
    Abstract: A device for measuring length and center of mass of conical workpiece, including an inner frame, an outer frame, a base plate, two laser displacement sensors and a plurality of weighing mechanisms. The inner frame is rotatably connected with the outer frame through a pin shaft. A bottom surface of the conical workpiece can be fixedly connected with an inner bottom surface of the inner frame. The base plate is removably arranged on the inner frame, and abuts against a top of the conical workpiece. The base plate is perpendicular to an axis of the conical workpiece. The laser displacement sensors are fixedly arranged at a position of the inner frame below the top of the conical workpiece. The weighing mechanisms are provided at a bottom of the outer frame, and can bear the inner frame, the outer frame and the conical workpiece.
