[0002] Tooling, or process equipment, refers to the various tools used in the manufacturing process. Frame positioning tooling is used to precisely position and clamp the vehicle frame during manufacturing.

[0003] The existing solution requires two sets of cylinders for the central positioning mechanism, one set is responsible for pushing the positioning mechanism to the specified position, and the other set is responsible for locking it. During actual operation, the two cylinders need to be pushed into place in turn, resulting in a slow production cycle. In addition, the existing solution requires the use of positioning cylinders and clamping cylinders for the rear positioning mechanism. After the rear component is hoisted onto the tooling, it needs to be roughly positioned manually first, and then the positioning mechanism is pushed out by the cylinder to achieve accurate positioning, and finally it is clamped by the clamping cylinder, resulting in low production efficiency.
