Pre-assembled platform general assembly alignment pin is separately positioned on corresponding boss.
Further, installation bolt after subframe when a pair of instrument vias are additionally provided with the pre-assembled platform to facilitate general assembly
Tightening tool passes through.
During pre-assembled, by the cooperation of each alignment pin and positioning hole, first power assembly and subframe be assembled to respectively pre-
On assembly bench.
During general assembly, the module assembly after pre-assembled is lifted upwards, first makes the pre-assembled platform general assembly on pre-assembled platform
With the pre-assembled platform general assembly positioning hole butt junction location on alignment pin and vehicle body, then by power assembly with being preloaded onto vehicle body
On left and right suspension carry out abutting joint, by subframe and vehicle body abutting joint.Power assembly is needed by pre-assembled platform, car
Body, suspend this three-level and be positioned into luggage and match somebody with somebody, dimension chain is shorter, and positioning precision improves, and assembly difficulty reduces, and saves installation time.
Subframe is assembled by the positioning of pre-assembled platform and vehicle body, and precision is subjected to.And the alignment pin of vehicle body is arrived on pre-assembled platform
It can reuse, greatly reduce cost.
The assembling location structure of the front-end module assembly has the advantages that：
（1）In the utility model, subframe and power assembly positioning precision distribution ratio are relatively average reasonable, general assembly man-hour drop
It is low, it is additionally, since on pre-assembled platform and is provided with a pair of pre-assembled platform general assembly alignment pins and vehicle body general assembly positioning, the alignment pin can
Recycling, enhances the versatility of pre-assembled platform, and cost substantially reduces.
（2）The utility model is simple in construction, practical, easy to spread.
