The invention relates to special clamping equipment for eccentric locking of a steering pump. The special clamping equipment comprises a main plate, a positioning plate, supporting rods, a positioning sleeve, a pressing plate and a fastening wrench. The positioning plate is arranged on the main plate. Each of the left side and the right side of the upper surface of the positioning plate is provided with the corresponding vertical supporting rod. The positions of the two supporting rods coincide with the positions of holes in the left side and the right side of a steering pump shell. The positioning sleeve vertically penetrates the center of the main plate and the center of the positioning plate. A pull rod is coaxially sleeved with the positioning sleeve. The upper end of the pull rod extends to the outer side of the positioning sleeve and is provided with the pressing plate, and the lower end of the pull rod is connected with the fastening wrench. The special clamping equipment for eccentric locking of the steering pump is ingenious in design, simple in structure and convenient and fast to use. By usage of the equipment, the workpiece dismounting and mounting time can be shortened, the work speed is increased, the work efficiency is improved, and the product quality is guaranteed.
