The utility model discloses a positioning fixture for bearing roller machining, which relates to the field of bearing roller machining and comprises a table plate, a shell is fixedly connected to the upper surface of the table plate, a first bearing is clamped to the rear side wall of the shell, and a rear end optical axis of a screw is sleeved with the first bearing. The rotating disc is reversely rotated to drive the screw rod to rotate, the screw rod enables the nut and the two first racks to move backwards through matching of the second sliding grooves and the sliding blocks in the rotating process, the first racks are meshed with the transmission gear in the backward moving process, and then the gear is meshed with the transmission gear second. Under the combined action of the sliding rod, the sliding sleeve, the first sliding groove and the connecting block, the two clamping plates get close to each other and clamp and fix the roller, so that the stability of the roller in the machining process is guara
