The invention provides a spring piece grabbing device, and belongs to the technical field of machining. The spring piece grabbing device comprises a grabbing and feeding mechanism and a support mechanism; light pipes of the support mechanism are placed on an arc support surface of a pipe bracket; a support slide block of the grabbing and feeding mechanism is arranged in a dovetail-shaped chute ofa frame in a front-back sliding manner; a feeding lead screw is rotationally arranged on a lead screw bracket, and is in threaded connection with the support slide block; the two ends of a driving cylinder are respectively connected with the support slide block and a T-shaped bracket; a guide module is arranged between the support slide block and the T-shaped bracket; the upper end of a support base is inserted in the T-shaped bracket, and is connected through a connecting pin shaft; the two ends of the connecting pin shaft are clamped through snap springs; a left spring piece and a right spring piece are symmetrically mounted at the left and right ends of the support base through connecting screws; and guide lugs are arranged at the lower ends of the left spring piece and the right springpiece. The spring piece grabbing device quickly realizes grabbing and feeding of the light pipes, and is reasonable and compact in structure and excellent in grabbing stability.
