Device for measuring length and center of mass of conical workpiece
A recently granted patent (Publication Number: US11988572B1) discloses a device designed for measuring the length and center of mass of conical workpieces. The device includes a base, support mechanism, measuring platform, torsion bar, torsional-pendulum drive and brake mechanisms, inner and outer frames, laser displacement sensors, weighing mechanisms, and a slewing bearing. The inner frame is connected to the outer frame through a pin shaft, with the base plate fixed to the conical workpiece and perpendicular to its axis. Laser displacement sensors and weighing mechanisms are strategically placed to facilitate accurate measurements. The torsion bar, drive, and brake mechanisms enable torsional pendulum movements for precise center of mass calculations.
Additionally, the device features a counterweight block for adjusting the center of mass, a slewing bearing for rotational measurements, and ball heads and sockets for stability during measurements. The device can accurately determine the Y-axis and Z-axis center of mass of conical workpieces in real-time, providing valuable data for various applications. Furthermore, the device allows for the measurement of the axial center of mass by rotating the conical workpiece horizontally and calculating the center-of-mass coordinate based on specific distances. The inclusion of jacking mechanisms ensures the measuring platform can be easily adjusted for optimal positioning during measurements, enhancing the device's overall functionality and precision.
