The invention relates to a workpiece equal-dividing type collecting device which comprises a conveyor belt and a workbench, wherein a slip rod is mounted on the workbench in a horizontal direction in a sliding mode; the inclined left side of the middle part on the slip rod is welded with a connecting frame; the right side of the connecting frame is provided with a waist-shaped control board; the outer side of the control board is provided with a ring of slide rails; the slide rails are in sliding connection to the left end surface of the connecting frame; a rotary shaft is arranged on the center of any semi-circular arc of two semicircular-arc centers of the control board; and the lower end of the rotary shaft is connected with a motor. Frameworks are mounted at both left and right sides of the slip rod; pushing bases which are mounted in a front-rear direction in a sliding mode are arranged in the frameworks; the rear ends of the pushing bases are connected and fixedly mounted on springs on the rear parts of the framework; the front ends of the pushing bases abut against ratchet wheels; and the ratchet wheels are connected with L-shaped pulling frames. In case of automatically controlling the slip rod to move left and right in a circulating mode, the workpiece equal-dividing type collecting device can carry out left-right equalizing on workpieces which are conveyed on the conveyor belt one by one, and can enable a great number of workpieces to carry out halving any-power assembly.
