The front subframe positioning portion and the front side member positioning portion are inherently structured, and reserved insertion holes for assembly are provided in the front subframe and the front side member at the time of manufacturing.
Further, the body includes first arm, and first location portion includes first locating pin and second locating pin, sets up two positions on the arm exhibition direction of first arm respectively, and preceding sub vehicle frame location portion includes first locating hole and second locating hole, and the distance of first locating hole and second locating hole equals the distance of first locating pin and second locating pin.
Further, the body further comprises a second arm part, and the second positioning part comprises a third positioning pin and is arranged on the second arm part; the front side member positioning portion includes a third positioning hole, and a distance between the first positioning hole and the third positioning hole is equal to a distance between the first positioning pin and the third positioning pin.
Further, a connecting rib is arranged between the first arm part and the second arm part. The connecting rib is added to further strengthen the overall stability of the structure in triangular connection, the connecting rib can strengthen the stability of the structure of the tool, and positioning errors caused by deformation of the positioning tool are prevented.
When the front auxiliary frame split-charging device is used, the splicing positions of the front extending beam, the front auxiliary frame and the front longitudinal beam are well corresponding, bolts and nuts are arranged on the connecting fixing holes, but tightening operation is not performed, positioning pins of a positioning tool are fixed at the positions of the corresponding front auxiliary frame positioning parts and the positioning holes of the front longitudinal beam positioning parts, position positioning and angle fixing are performed, then bolts and nuts at the connecting positions of the three components are tightened, high-precision assembly of the components is realized, distortion deformation does not exist on the fixing angles and fixing surfaces of the three components, finally, the assembled front auxiliary frame split-charging assembly is mounted on a vehicle body, and due to high assembly precision, the front auxiliary frame split-charging assembly and the vehicle body are high in mounting matching degree, good in precision and high in one-time mounting qualification rate, and the repairing phenomenon is reduced.
Further, the tail end of the first arm part in the arm stretching direction is higher than the tail end of the second arm part in the arm stretching direction, and the third positioning pin is lower than the first positioning pin.
It should be noted that, the axes of the first locating pin, the second locating pin and the third locating pin are not in the same plane and form a triangle state, so that the dimensions of each direction of a single locating tool can be fixed, the plane of the lower end head of the third locating pin is lower than the plane of the lower end heads of the first locating pin and the second locating pin, a three-dimensional locating tool with depth can be formed, and the longitudinal installation height difference of three assemblies is limited.
Further, the first positioning pin comprises a first plug pin and a first abutting column which are coaxially connected, and the second positioning pin comprises a second plug pin and a second abutting column which are coaxially connected. The first plug pin, the second plug pin and the third locating pin are used for plugging corresponding locating holes, the first abutting column and the second abutting column are abutted above the locating holes, the diameters of the first abutting column and the second abutting column are different, the plug pin plays a role in plugging, and the abutting column forms a clearance space between a triangular surface formed by the connecting rod and the installation surface to facilitate tightening operation.

The transition chamfer can improve the smoothness of the insertion pin entering the preformed hole, and improve the installation efficiency of the positioning tool.
Further, the first arm part, the second arm part and the connecting ribs are respectively fixed by the connecting seat, and the first locating pin, the second locating pin and the third locating pin are respectively fixed on the connecting seat. Because the heights of the three pins are inconsistent, the connecting seat has a deep structure, and the connecting seat is used for connecting the two adjacent connecting rods and the pins, the connecting rod structure is not required to be too complex, and the manufacturing cost and the difficulty can be reduced.
Generally, the length of the first abutment post and the second abutment post ranges from 10mm to 15mm, and the length of the first plug pin, the second plug pin and the third positioning pin is shorter than the hole height of the corresponding positioning hole. The length of first grafting round pin, second grafting round pin and third locating pin is shorter than the hole height of locating hole can guarantee the quick grafting of location frock, can not lead to the plug inconvenient because the grafting degree of depth is too long, influences installation effectiveness, and first butt post and second butt post butt are in the locating hole top, can form the support of a take degree of altitude, and the convenience staff carries out the equipment operation, and bolt and nut tightening operation of three subassembly can not be disturbed to structures such as connecting rod.
Generally, the diameters of the first plug pin and the second plug pin are smaller than the diameters of the first positioning hole and the second positioning hole on the front auxiliary frame by 0.6mm-1.2mm, and the diameter of the third positioning pin is smaller than the diameter of the third positioning hole on the front longitudinal beam by 0.2mm-0.6mm. The diameter of locating hole design is bigger than the diameter of grafting round pin slightly, makes things convenient for the plug of grafting round pin, and secondly because the structural dimension of front longitudinal beam is less for preceding sub vehicle frame, the locating hole size of front longitudinal beam is less than the locating hole size of front sub vehicle frame, so the interference that the preformed hole of front longitudinal beam can provide is little.
Further, the third positioning hole is located at one end of the front longitudinal beam, which faces away from the front auxiliary frame. If the positioning plane formed by the first positioning pin, the second positioning pin and the third positioning pin is too small, the error is amplified after the size is amplified in equal proportion, so that the positioning precision is insufficient, and therefore, the positioning position of the third positioning hole corresponding to the third positioning pin can be as close to the joint of the three components as possible, and the positioning precision can be improved.
The utility model also provides an assembly tool for the front auxiliary frame sub-assembly, which comprises at least two assembly tools, wherein the structures of the at least two assembly tools are symmetrically distributed.
