Detailed Description

The precision guarantee structure of the front electronic module of the present invention will be further described below with reference to specific embodiments to help those skilled in the art to understand the technical solution of the present invention more completely, accurately and deeply.

Example 1

As shown in fig. 2 to 5, the Front Electronic Module (FEM) accuracy assurance structure of the present embodiment includes a front end plate 10 and a front electronic module body 20. The front end plate 10 comprises a longitudinal beam attaching surface 13 and two mounting surfaces 15 located on one side of the longitudinal beam attaching surface 13, mounting through holes 11 and limiting grooves 12 are formed in the mounting surfaces 15, the mounting through holes 11 are long round holes, and the length direction of the mounting through holes is the X direction. The two mounting surfaces 15 are arranged at intervals, the limiting groove 12 in the upper mounting surface 15 is of an L-shaped groove structure, and the limiting groove 12 in the lower mounting surface 15 is of an opening structure. Mounting nuts 22 and positioning pins 21 are arranged at positions of the front electronic module body 20 corresponding to the two mounting surfaces 15, the positioning pins 21 are matched with the limiting grooves 12 to control the X direction and the Z direction of the front electronic module 20, bolts are mounted to the mounting nuts 22 through mounting through holes 11 to fix the front electronic module 20 and control the Y direction of the front electronic module 20; the stringer faying surface 13 is fixed to the stringer assembly to ensure the overall position of the front portion.

The assembly process of the Front Electronic Module (FEM) precision assurance structure of the present embodiment is as follows:

(1) the front end plate 10 is fixed with the longitudinal beam assembly through the longitudinal beam binding surface 13, and the integral position of the front part is ensured;

(2) the front electronic module body 20 is matched with the limit groove 12 through a positioning pin 21 to control the X/Z direction of the FEM body 20;

(3) the FEM body 20 is fixed by being mounted to the mounting nut 22 through the mounting via hole 11 using a bolt, and the Y direction of the FEM body 20 is controlled.

The precision guarantee structure of the front electronic module changes the structure and the welding sequence, so that the front end plate of the longitudinal beam is welded at a lower vehicle body assembly station or a cabin assembly station, the tolerance accumulation is reduced, and the stability of the front end plate is guaranteed; the mounting position of the front end plate of the longitudinal beam and the FEM is changed into an X-direction long circular hole, and the X direction is adjusted; two positioning pins are preset in the FEM and matched with the front end plate of the longitudinal beam to control the Z direction of the FEM.

For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial modifications are possible within the protection scope of the present invention as long as the method concept and technical solution of the present invention are adopted.
