| Zusammenfassung: | A system error compensation apparatus for quadratic element measuring equipment is composed of a main line rail, an auxiliary line rail, a work platform, a grating ruler, an upper crossbeam, a middle crossbeam, a lower crossbeam, a middle vertical beam, a right vertical beam, a left vertical beam and a main beam. The system error compensation apparatus is characterized in that the main beam is arranged on the work platform, the main line rail and the auxiliary line rail are positioned at two ends of the main beam, and the grating ruler is disposed in the middle of the main beam. The apparatus of the utility model helps to solve problems that a conventional system error compensation apparatus is poor in compensation effect for large-stroke gantry type quadratic element measuring equipment. |
