Where IT refers to the tolerance of each link dimension, which is a manufacturing accuracy requirement for these dimensions. Comparing the two schemes, the requirement on the accuracy of the Z-direction dimension position of the lock and the lock catch is +/-0.3 mm as an accepted standard (in the range, the problems of shaking and abnormal sound of the padlock are not caused when the vehicle door is closed), referring to the normal distribution diagram shown in fig. 10 and 11, the abscissa represents the tolerance, and the ordinate represents the probability of distribution of different tolerance samples in the assembling process, it can be seen from the diagram that the out-of-tolerance defect rate of the scheme I assembled by using the self-positioning lock catch is 26.77%, and the out-of-tolerance defect rate of the scheme II assembled by using the tool is 3.42%. Considering the production cycle of 60JPH in 8 hours in one day, 480 cars are required to be adjusted, the number of cars required to be adjusted can be reduced from about 130 cars to 17 cars, and thus the number of people can be reduced to 3 when the adjustment personnel (generally 5 people, 1 person is responsible for the front part, 1 person is responsible for the back part, 2 people is responsible for the side surface, and 1 person is responsible for the whole customs clearance, defect card counting and data counting) of the line repair station are finished.
The principle of the vehicle door latch assembling and positioning tool provided by the embodiment of the invention is as follows:
the tooling is positioned and installed on a vehicle body 7 with a hinge behind a disassembled vehicle door through an upper hinge positioning mechanism 2 and a lower hinge positioning mechanism 3, the tooling is positioned and installed in the area of a side wall rear wheel cover 73 through a side wall rear wheel cover positioning mechanism 4 at the rear part, a matched area of a latch 6 meshed with a vehicle door lock is positioned through a latch positioning mechanism 5, on the premise of adopting a latch without a positioning pin, the problem of the position accuracy of the latch 6 assembled on the vehicle body is solved, the cost of the latch 6 is reduced, the assembling and adjusting workload of the latch 6 is reduced, the original 2-person dedicated left and right vehicle door latch adjusting work is changed into the front and rear adjusting work for checking and adjusting, compared with a self-positioning latch, the position matching size chain of the latch 6 and a door lock is shortened, the range is reduced from +/-0.74 mm to +/-0.43 mm, the quality requirements of opening and closing of the vehicle door are met, and the workload of secondary adjustment is greatly reduced,
