After the hinge assembly is completed, when the part is taken, the tooling is opened in the following sequence: firstly, the air cylinder of the hinge positioning unit 3 is opened, then the secondary sliding unit 2 is retracted downwards, and the final sliding unit 1 is retracted backwards, so that the whole tool is in a full-open state, and then the workpiece taking operation can be performed, and the open states of the units at all levels are introduced one by one. When the cylinder of the hinge positioning unit 3 is opened, the cylinder drives the pressure head 305 to release the compression of the hinge. At this time, the hinge positioning unit 3 and the secondary sliding unit 2 are both in an open state, and the secondary sliding unit 2 slides down to the retraction limiting position, so as to drive the hinge positioning unit 3 to withdraw downward, and the hinge pin 43 withdraws from the positioning sleeve 310. At this time, the hinge positioning unit 3, the secondary sliding unit 2 and the primary sliding unit 1 are all in an open state, and the primary sliding unit 1 slides downwards to a retreating limit position, so that the hinge positioning unit 3 and the secondary sliding unit 2 are driven to retreat backwards, the whole positioning tool leaves the part to be assembled, and enough space is ensured so that the part can be taken out in a vertical direction without barriers. When the whole positioning tool is in the all-open state, the whole positioning tool is separated from the assembled part, and the assembled door outer plate 5 can be taken out vertically without barriers.
By the structural design of the hinge positioning tool, the positioning of the hinge axis 45 is realized, and under the structural form of the invention, the hinge axis 45 is a positioning main reference, the limit form of the original scheme is abandoned, and the influence on the position of the hinge axis 45 in the positioning process due to the precision problem of the hinge is avoided; in addition, under the structural form of the invention, the axial positions of the upper hinge and the lower hinge can be independently adjusted, when the position of the hinge axis 45 deviates, the optimization of the axial position can be realized through an adjusting tool, and the invention is very beneficial to solving the quality problem of the vehicle door caused by the coaxiality of the hinge; finally, by using the multistage sliding mechanism, the invention can realize the positioning of the hinge axis 45 and simultaneously ensure that the door outer plate 5 can be taken along the vertical direction without obstacle after the door hinge 4 is assembled, thereby greatly reducing the operation difficulty of the transportation.
