The present invention relates to a device for quickly measuring the verticality of the lip edge surface and the handle of a hemispherical resonator, comprising a hemispherical resonator, a workbench, a comparator and a pin. The hemispherical resonator comprises a handle and a hemispherical body, one end of the handle is fixedly connected to the hemispherical body, and the handle is located at the center of the hemispherical body; the end face of the hemispherical body is a lip edge; the workbench is a cylindrical table, and a cylindrical hole is opened at the central axis position of the cylindrical table; a probe hole is opened on the side wall of the cylindrical table, and the probe hole is connected to the cylindrical hole, and the probe of the comparator can be inserted into the probe hole; the handle of the hemispherical resonator is placed in the cylindrical hole, and the lip edge is tightly fitted with the upper end face of the workbench; the pin is located on the workbench, and is used to limit the positional relationship between the hemispherical resonator and the comparator. The device used for measurement of the present invention is exquisite, simple, occupies little space, and has low cost, and provides theoretical and practical support for real-time measurement and inspection during the research and processing of the lip edge of the hemispherical resonator.
