The utility model provides a sensor four-corner error measuring device convenient for weight positioning and replacement, which relates to the technical field of measuring devices and comprises a four-corner adjusting device mounting table, a mounting plate is mounted at the top end of the four-corner adjusting device mounting table, and a spherical weight base is fixed on one side of the top end of the mounting plate. The second ball vortex arranged at the top end of the spherical weight base is used for placing the spherical weight body, the second ball vortex enables the spherical weight body to stand and be fixed, the height of the second ball vortex is flush with the scale body, a certain gap is reserved between the second ball vortex and the scale body, and the weighing sensor body is convenient to replace while sensor testing is not affected. The spherical weight main body can move into the first guide groove along the second guide groove and roll to a designated position to prevent from rolling off from the scale main body, and the spherical weight main body can roll the spherical weight main body to five first ball vortexes on the scale main body through the first guide groove so as to be used for measuring the four-corner error of the sensor.
