Tail cover machining tool capable of achieving machining forming through one-time clamping

The utility model belongs to the technical field of tail cover machining, and particularly relates to a tail cover machining tool capable of achieving machining forming through one-time clamping. Thetail cover machining tool capable of achieving machining forming through one-time clamping comprises a clamping jaw, a core rod and a compression washer, the core rod is arranged on the clamping jaw,a convex top end is arranged at the end of the core rod, and the compression washer is fixed to the portion, corresponding to the convex top end, of the core rod through a screw. The clamp has the advantages that the problem that the tail cover can be machined and formed only through two-time clamping is solved, the tail cover can be machined and formed only through one-time clamping without turning around and turning, the structure is simple, clamping is reliable, and the machining precision is greatly improved. 本实用新型属于尾盖加工技术领域，具体涉及一种一次装夹即可加工成形的尾盖加工工装。该一次装夹即可加工成形的尾盖加工工装，包括卡爪、芯棒和压紧垫圈，所述卡爪上设有芯棒，芯棒端部设有凸顶端，所述芯棒对应凸顶端通过螺钉固定
