The invention provides a special tool for hoisting a piston head and a using method, the special tool comprises a first arc-shaped hoop and a second arc-shaped hoop which are arranged in pairs, first lug plates are symmetrically arranged at the opening end of the first arc-shaped hoop, and second lug plates are symmetrically arranged at the opening end of the second arc-shaped hoop; the first arc-shaped hoop and the second arc-shaped hoop are clamped outside the piston head and are fixedly connected through a bolt assembly; a first hoisting rod is fixed on the outer wall of the arc-shaped middle part of the first arc-shaped hoop, and a second hoisting rod is fixed on the outer wall of the arc-shaped middle part of the second arc-shaped hoop. The hoisting tool is suitable for accurate and safe hoisting in the surfacing process of the corrosion-resistant nickel-chromium alloy material of the piston head of the large-cylinder-diameter diesel engine by adopting a welding robot, so that high-efficiency batch production is facilitated; and the piston head can be conveniently and safely lifted by a lifting worker, and the piston head is prevented from falling off in the process of using a magnet to lift due to overhigh surfacing temperature.

    本发明提供了一种活塞头起吊专用工装及使用方法,包括成对布置的第一弧形箍和第二弧形箍,第一弧形箍的开口端对称设置有第一耳板,第二弧形箍的开口端对称设置有第二耳板;第一弧形箍和第二弧形箍抱夹在活塞头的外部并通过螺栓组件固定相连;第一弧形箍的弧形中间部位的外壁上固定有第一吊装杆,第二弧形箍的弧形中间部位的外壁上固定有第二吊装杆。通过此起吊工装适用于采用焊接机器人进行大缸径柴油机活塞头耐腐蚀镍铬合金材料堆焊过程中的精准安全起吊,以便进行高效率批量生产;便于起重工进行安全起吊,防止因堆焊温度过高使用磁贴吊过程中活塞头掉落情况发生。
