However, when the existing machine cover assembly process and the existing machine cover assembly tool are used for encircling type car bodies, the following problems exist:

1) The existing car body cover installation positioning tool and car body positioning technology adopt a round pin and round hole matching technology, so that X-direction short circuit between the car cover and the car door profile cannot be realized. Further, the assembly tolerance of the X-direction gap between the cover and the fender (the fender takes the contour of the vehicle door as a positioning reference) is large, and the assembly efficiency is affected by circuitous adjustment.

2) The existing car body cover installation positioning tool and car body positioning adopt a round pin round hole matching process, and short circuit and centering of Y-direction surfaces of a car cover and a car door cannot be realized, so that Y-direction deviation exists after installation of the car cover, circuitous adjustment is needed, and the adjustment efficiency is affected.

3) The existing car body cover installation positioning tool adopts a hole/pin process to position the cover, so that Y-direction profile short circuit between the cover and a fender/headlight cannot be realized, and X-direction profile short circuit between the cover and a front bumper is not realized. The Y-direction gap/surface difference assembly precision of the cover and the fender cannot be guaranteed, and the X-direction precision requirement of the cover and the fender/headlight/front protection profile cannot be guaranteed.
