As shown in fig. 11, when the door upper and lower hinge axes 45 are ensured to be in a straight line, i.e. the coaxiality of the upper and lower hinge axes 45 is ensured, the hinge can be assembled, and as shown in the figure, the air gun 6 can pass through the hinge mounting hole 42 through a bolt and fix the hinge on the door outer panel 5, so that the assembling work of the door hinge 4 can be completed.
After the hinge assembly is finished, when a workpiece is taken, the tool is opened in the following sequence: firstly, the hinge positioning unit 3 is opened by a cylinder, then the second-stage sliding unit 2 retracts downwards, and the last-stage sliding unit 1 retracts backwards, so that the whole tool is in a fully opened state, then the workpiece taking operation can be carried out, and the opened states of all stages of units are introduced one by one. When the hinge positioning unit 3 is opened, the air 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 downwards to a return limiting position, so that the hinge positioning unit 3 is driven to withdraw downwards, and the hinge pin shaft 43 is led to withdraw from the positioning sleeve 310. Hinge positioning unit 3, second grade unit 2 and the one-level unit 1 that slides all are in the open mode this moment, and the one-level unit 1 that slides is to the limit position that returns of sliding downwards to drive hinge positioning unit 3 and second grade unit 2 that slides and withdraw from backward, make whole location frock leave by the dress part, ensure to have enough space to make the part can follow the accessible of vertical direction and take out. When the whole positioning tool is in a fully opened state, the whole positioning tool leaves the mounted part at the moment, and the assembled outer door panel 5 can be taken out vertically without barriers.
The hinge positioning tool is structurally designed to realize the positioning of the hinge axis 45, and in the structural form of the hinge positioning tool, the hinge axis 45 is the main positioning reference, so that 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 accuracy problem of the hinge is avoided; in addition, under the structural form of the invention, the axial line 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 line position can be realized by adjusting a tool, and the invention is very beneficial to solving the quality problem of the car door caused by the coaxiality of the hinges; finally, the invention can ensure that the outer door plate 5 can be taken out without barriers along the vertical direction after the door hinge 4 is assembled by using the multi-stage sliding mechanism while realizing the positioning of the hinge axis 45, thereby greatly reducing the difficulty of power transportation operation.
