Bearing seat machining tool

The utility model discloses a bearing seat machining tool which comprises a cylindrical sleeve, and a bearing seat mounting hole concentric with the center of a bearing seat to be machined is machined in the center of the cylindrical sleeve. A locking screw hole communicated with the bearing seat mounting hole is formed in the side wall of the cylindrical sleeve, and a bolt for fixing the bearing seat is mounted in the locking screw hole. The bearing seat is fixed through the cylindrical sleeves, the cylindrical sleeves and the cylindrical sleeves are concentrically installed, the datum of a bearing seat hole is converted to the outer circle of the tool full-circle sleeve, and a universal grinding machine can conveniently clamp the bearing seat. 本实用新型公开了一种轴承座加工工装，包括圆柱套，所述圆柱套中心加工有与待加工轴承座中心同心的轴承座安装孔；所述圆柱套侧壁设置有与轴承座安装孔连通的锁定螺孔，所述锁定螺孔安装有用于固定轴承座的螺栓。其通过圆柱套实现轴承座固定，圆柱套与圆柱套同心安装，将轴承座孔的基准转换到了工装整圆套的外圆上了，便于万能磨床对轴承座的装夹。
