The positioning method of the positioning carrier for hinge assembly according to claim 8, characterized in that: The following steps are involved: (1) Positioning of the adjusting block: The adjusting block is transported to the positioning mechanism of the oil cylinder so that the groove on the adjusting block engages with the "convex"-shaped positioning undercut and positioning boss on the support seat. At the same time, the stopper and baffle on the support seat respectively position the circumference of the adjusting block; (2) Positioning of the rocker: The rocker is transported to the rocker positioning mechanism so that the rocker is placed on the inclined positioning surface of the rocker positioning block. A strong magnet is embedded in the rocker positioning block, which fits tightly with the rocker and is locked and fixed with the positioning lock on the fixing seat, so that the rocker and the adjustment block are assembled with each other and the coaxial alignment of the riveting holes at the joint is achieved; (3) Spring positioning: install the spring in the rocker and make the spring coaxially located at the rivet hole after the rocker and the adjusting block are aligned with each other, insert a rivet into the rivet hole, rivet the rocker and the adjusting block together, and position the spring in the rocker; (4) Position the cylinder assembly. After pressing down the spring through the pressure rod, assemble the cylinder assembly on the adjusting block and the rocker. The cylinder on the cylinder assembly is supported by a support rod against its bottom. The rivet hole on the cylinder is coaxially aligned with the rivet hole on the adjusting block, and the rivet is installed. (5) Assembling the outer frame: Install the outer frame on the rocker after it is assembled with the cylinder assembly, position and assemble the rocker and the outer frame on the rocker positioning block respectively, align the riveting holes of the two coaxially, and insert the U-shaped pin to complete the assembly.
