Zusammenfassung: | The utility model discloses a calibration device. The calibration device comprises a driving device; the driving shaft is connected with the driving device through a bolt; the driving shaft is provided with a mounting flange, and a plurality of first mounting holes which are non-uniformly distributed are formed in the mounting flange; the connecting shaft can be connected with an encoder to be tested; a plurality of first connecting holes which are non-uniformly distributed are formed in the end surface of the connecting shaft; the reference encoder is connected with the connecting shaft; the first mounting holes and the first connecting holes are in one-to-one correspondence in position, and pins are inserted into the first mounting holes and the first connecting holes to position the driving shaft and the connecting shaft. According to the technical scheme, it can be guaranteed that the driving device, the reference encoder and the to-be-tested encoder are concentrically arranged, so that the concentricity |
