Welding auxiliary operation tool

The welding auxiliary operation tool comprises a bottom plate, damping columns are fixedly connected to the periphery of the top of the bottom plate, a movable plate is arranged in an inner cavity of each damping column, a damping rod is fixedly connected to the top of each movable plate, and a machining table is fixedly connected to the top of each damping rod. And electric sliding tables are fixedly connected to the two sides of the top of the machining table, sliding rods are slidably connected to inner cavities of the electric sliding tables, concave blocks are fixedly connected to one ends of the sliding rods, and fastening bolts are in threaded connection to inner cavities of the tops of the concave blocks. Through the arrangement of the electric sliding table, the sliding rod, the concave block, the fastening bolt, the bearing and the clamping plate, the problems that an existing auxiliary device is simple in structure and can only play a role in bearing, workpieces with different thicknesses cannot be
