Detailed Description
The present invention will be described in further detail with reference to fig. 1 to 5.
A vehicle body positioning mechanism of a front end module comprises a frame 10 positioned with the front end module, wherein a coarse positioning mechanism 20 and a fine positioning mechanism 30 are arranged below the frame 10, the coarse positioning mechanism 20 and a reinforcing beam 1 on a front wheel cover form horizontal positioning and vertical positioning, and the fine positioning mechanism 30 and a mounting plate of a fender 2 form horizontal positioning and vertical positioning.
In the scheme, the front end module and the auxiliary tool thereof are moved to the rough positioning mechanism 20 to be positioned with the reinforcing beam 1 on the front wheel cover, the approximate installation position of the front end module is determined, the positions of the front end module and the auxiliary tool thereof are finely adjusted to position the fine positioning mechanism 30 with the installation plate of the fender 2, and at the moment, the front end module reaches the accurate installation position to be installed with the front end module. The accurate precision of location is higher like this, and difficult collision damage fender 2 among the positioning process, is favorable to the assembly of front end module.
The coarse positioning mechanism 20 includes positioning claws vertically arranged at two sides below the frame 10, the lower ends of the positioning claws are composed of a first, a second and a third positioning blocks 21, 22 and 23, and the first, the second and the third positioning blocks 21, 22 and 23 are respectively contacted with the front, the inner and the upper surfaces of the reinforcing beam 1 on the front wheel cover during initial positioning. The first positioning block 21 is in contact with the front end surface of the front wheel cover upper reinforcing beam 1 to form positioning in the vehicle length direction, the second positioning block 22 is in contact with the inner side surface of the front wheel cover upper reinforcing beam 1 to form positioning in the vehicle width direction, and the third positioning block 23 is in contact with the upper surface of the front wheel cover upper reinforcing beam 1 to form positioning in the vertical direction, so that rough positioning in three directions of the front end module is completed, the approximate installation position of the front end module is determined, and subsequent installation is facilitated.
The lower ends of the first positioning block 21 and the second positioning block 22 are wedge-shaped, and the lower ends of the wedge-shaped blocks are far away from the upper reinforcing beam 1 of the front wheel cover. The situation that the first and second positioning blocks 21 and 22 interfere with the reinforcement beam 1 on the front wheel cover to cause the vertical positioning failure when the coarse positioning mechanism 20 moves up and down is avoided.
The fine positioning mechanism 30 includes vertical positioning mechanisms 31 disposed on two sides below the frame 10, a vertical positioning block 311 is disposed at a lower end of the vertical positioning mechanism 31, and a lower surface of the vertical positioning block 311 contacts with an upper surface of a mounting plate of the fender 2 during positioning. When the vertical positioning block 311 is thus in contact with the mounting plate of the fender 2, the front end module has a fine positioning in the vertical direction.
The fine positioning mechanism 30 includes horizontal positioning mechanisms 32 disposed on two sides below the frame 10, and a positioning pin 321 disposed at a lower end of the horizontal positioning mechanism 32 and having an axis direction in a vertical direction is disposed, and the positioning pin 321 is inserted into a positioning hole in the mounting plate of the fender 2 during positioning. When the positioning pin 321 is inserted into the positioning hole in this way, the front end module has a finished positioning in the vehicle length and width directions.
And a centering mechanism 40 for keeping the two-side positioning mechanisms centered is arranged between the two-side coarse positioning mechanisms 20 and between the two-side fine positioning mechanisms 30. Thus, the width between the two-side coarse positioning mechanisms 20 and the two-side fine positioning mechanisms 30 is adjusted, the centering is always kept, the positioning precision of the positioning mechanisms is ensured, and the front-end module is prevented from deviating from the installation position of the front-end module.
A handle 322 is transversely arranged on the outer side of the horizontal positioning mechanism 32. The handle 322 is arranged to facilitate the personnel to support the position of the fine adjustment auxiliary tool to achieve accurate positioning.
The horizontal positioning mechanism 32 is provided with an air cylinder 323 for controlling the elevation of the positioning pin 321. If the positioning pin 321 is not completely aligned with the positioning hole when the horizontal positioning mechanism 32 is lifted along with the tool aid, the fender can be damaged by the positioning pin 321, the positioning pin 321 can be retracted when the horizontal positioning mechanism 32 is lifted along with the tool aid due to the arrangement of the lifting positioning pin 321, and the positioning pin 321 is inserted into the positioning hole to complete horizontal positioning after the positioning pin 321 is completely aligned with the positioning hole.
