The invention discloses a centrifugation test clamp with a fiber type Y waveguide device. The centrifugation test clamp comprises a cover plate, an outer gasket, an inner gasket and a device mountingseat which are sequentially mounted from outside to inside, wherein an end surface of the device mounting seat is provided with a column-shaped groove, a plane of a bottom portion of the groove is atleast provided with a fixed groove A which is matched with the to-be-tested Y waveguide device in size and shape, a fixed groove B used for fixing fiber is arranged between the middle portion of the fixed groove A and an edge of the bottom portion of the groove, the fixed groove A and the fixed groove B are mutually communicated, and the inner gasket is provided with a pad A which extends towardsthe fixed groove A and is mutually matched with the fixed groove B. The centrifugation test clamp is advantaged in that a problem of low work efficiency caused by replacement of the clamp during a centrifugation test, a vibration test and an impact test existing in a Y waveguide device in the prior art is solved, efficiency of the Y waveguide device during a mechanical test is substantially improved, and the completion time of three tests accomplished by the Y waveguide device is shorted by one third.
