This invention discloses a dual-station steering gear housing machining fixture in the same direction and its usage method. It includes a base with a first machining position on the base. The first machining position has a first mounting surface (higher on the outside, lower on the inside) and a second mounting surface. The first mounting surface is located on the left side of the first machining position, and the second mounting surface is located on the right side. A left-section positioning mechanism is disposed on the first mounting surface for positioning the left half of the steering gear housing. A middle-section support and clamping mechanism is disposed on the left half of the second mounting surface for supporting, clamping, and positioning the middle section of the steering gear housing. A right-section positioning mechanism is disposed on the right half of the second mounting surface for positioning the right half of the steering gear housing. This invention effectively avoids dimensional deviation problems, improves the stability and accuracy of clamping, effectively reduces production costs, significantly reduces the probability of human error, and significantly reduces equipment modification costs.
