The utility model relates to a railway vehicle accessory machining clamp, in particular to a special positioning clamp for machining an inclined plane of an axle box lining plate. The device is characterized by comprising a horizontally-arranged bottom plate, an obliquely-arranged supporting plate is arranged on the bottom plate, the sum of the inclination angle of the supporting plate and the inclination angle of the inclined face of the axle box lining plate is equal to 90 degrees, and the distance between the upper side face and the lower side face of the supporting plate is larger than orequal to the distance between two boss vertical faces of the axle box lining plate; and a pressing mechanism is arranged on the bottom plate on one side of the supporting plate. The clamp is low in machining cost. 本实用新型涉及一种铁路车辆配件加工夹具，具体说是轴箱衬板斜面加工专用定位夹具。它的特点是包括水平布置的底板，底板上有倾斜布置的支撑板，支撑板的倾斜角度与轴箱衬板斜面的倾斜角度之和等于90度，支撑板的上侧面到下侧面的距离大于等于轴箱衬板两个凸台竖向面间的距离；所述支撑板一侧的底板上有压紧机构。采用该夹具的加工成本较低。
