The invention discloses a special fixture for fixed-point residual stress gradient detection of a bearing outer ring channel, belongs to the technical field of outer ring fixtures, and aims to solve the problems that a special fixture for residual stress gradient detection does not exist in the prior art, so that a measurement position deviates in a bearing outer ring residual stress detection process, and the measurement position cannot be ensured to be the last measurement position. The clamp comprises a layer stripping depth measuring unit, an outer ring clamping unit and a base, the layer stripping depth measuring unit and the outer ring clamping unit are both arranged on the upper surface of the base, the layer stripping depth measuring unit is fixedly connected with the upper surface of the base, and the outer ring clamping unit is fixedly connected with the upper surface of the base. The outer ring clamping unit is arranged on the front side of the layer stripping depth measuring unit, the outer ring c
