The invention relates to the technical field of vehicle manufacturing, and discloses a rear suspension assembly positioning tool which comprises a base body, a main positioning pin and an auxiliary positioning pin. The main positioning pin comprises a first assembly section matched with an assembly hole of the frame and a first installation section matched with an installation hole of the rear suspension, the maximum radial size of the first assembly section is Amm, and A is the sum of the diameter and the lower tolerance of the assembly hole of the frame; the maximum radial size of the first mounting section is Bmm, and B is the sum of the diameter and the lower tolerance of a mounting hole of the rear suspension; the auxiliary positioning pin comprises a second assembly section matched with an assembly hole of the frame and a second installation section matched with an installation hole of the rear suspension, the maximum radial size of the second assembly section is C mm, and C is the sum of the diameter and the lower tolerance of the assembly hole of the frame; and the maximum radial size of the second mounting section is Dmm, and D is the sum of the diameter of the mounting hole of the rear suspension and the lower tolerance. The radial sizes of the main positioning pin and the auxiliary positioning pin are limited, the gap problem between the bolt and the through hole is solved, and the problem that the upper portion deflects when the rear suspension is assembled is avoided.
本发明涉及车辆制造技术领域,公开了一种后悬装配定位工装,包括基体、主定位销和副定位销;主定位销包括与车架的装配孔配合的第一装配段和与后悬的安装孔配合的第一安装段,第一装配段的最大径向尺寸为Amm,A为车架的装配孔的直径与下公差之和;第一安装段的最大径向尺寸为Bmm,B为后悬的安装孔的直径与下公差之和;副定位销包括与车架的装配孔配合的第二装配段和与后悬的安装孔配合的第二安装段,第二装配段的最大径向尺寸为Cmm,C为车架的装配孔的直径与下公差之和;第二安装段的最大径向尺寸为Dmm,D为后悬的安装孔的直径与下公差之和。对主定位销、副定位销的径向尺寸进行限定,弥补螺栓与通孔的间隙问题,避免后悬装配时上部偏摆的问题。
