Abstract
The invention discloses a steering knuckle positioning fixture which comprises a base plate. The base plate is fixedly connected with a steering knuckle front section positioning unit and a steering knuckle rear section positioning unit. The steering knuckle front section positioning unit comprises a steering knuckle storing unit and two steering knuckle limiting column units. The steering knuckle storing unit comprises a first cylinder, a second cylinder and a third cylinder, a spring is connected between the first cylinder and the second cylinder. The upper end face of the second cylinder and the lower end face of the third cylinder are fixedly connected together, and the diameter of the second cylinder is larger than that of the third cylinder. Each steering knuckle limiting column unit comprises a supporting column and a first U-shaped clamping block fixedly connected to the upper end face of the supporting column. The steering knuckle positioning fixture has the advantages of being simple and reasonable in structure, low in price, convenient to mount and use and high in positioning accuracy.
