And the key size of the positioning block is designed in a drawing, and is the size which is reflected from the center line to the two sides and back and forth, and because the front-section frame framework assembly is closely matched with the tool assembly for positioning, the positioning block is stressed and deformed to carry out multiple verification tool positioning due to the welding deformation stress of the framework assembly during the postweld demoulding, and the labor intensity of the repeated measurement tool is greatly increased. The existing tool for the front section frame framework assembly cannot be used for positioning a suspension bracket, the suspension bracket is usually welded according to size measurement after the assembly of the frame assembly is completed, and therefore when an independent suspension car is installed in an assembly workshop, the problem of size deviation can also cause the phenomenon that the car is installed and a suspension system is difficult to assemble, the design structure of the front section frame is short, the framework space is very small, and the operation difficulty is very high if reworking operation is performed in a limited space.

Because the assembly space of the frame and the chassis is limited, and each connecting part is also required to be installed in the limited installation space, the front axle installation assembly and the suspension frame are assembled by screwing the nut end, and a certain torque is ensured. Because the front part of the frame is independently suspended, a suspension bracket is welded on the frame. The front section comprises main components such as a left shock absorber support, a right shock absorber support, a left stabilizer bar support, a right stabilizer bar support, a left front limiting block support and a right front limiting block support, and after the frame assembly is welded, secondary assembly work is carried out on a chassis suspension system station and a front axle assembly. The process control of relevant assembly sizes such as forming and welding of a suspension bracket by the group of the front frame framework plays a key role in traction force, braking force and corresponding reaction torque transmitted by an automobile chassis.
