Detailed Description
The invention will be further described with reference to the accompanying drawings:
referring to fig. 1-2, a white rear suspension remanufacturing and positioning structure comprises a base 1, wherein a reference positioning pin 2, a buffering reference positioning pin 4, a spring mounting seat positioning cylinder 5, a spiral spring front lifting lug positioning sleeve 6 and a spiral spring rear lifting lug positioning sleeve 7 are sequentially arranged on the left side of the base 1 from the front end to the rear end; a reference positioning pin 2, a beam lifting lug positioning round sleeve 3, a buffering reference positioning pin 4, a spring mounting seat positioning cylinder 5, a spiral spring front lifting lug positioning sleeve 6 and a spiral spring rear lifting lug positioning sleeve 7 are sequentially arranged on the right side of the base 1 from the front end to the rear end;
the same component in the left and right sides of the base is symmetrically arranged, the reference positioning pin 2, the cross beam lifting lug positioning round sleeve 3, the buffering reference positioning pin 4, the spring mounting seat positioning cylinder 5, the front lifting lug positioning sleeve 6 of the spiral spring and the rear lifting lug positioning sleeve 7 of the spiral spring are fixedly connected to the base through connecting cylinders respectively, the connecting cylinders are vertically arranged, the height and the spacing distance of the connecting cylinders are set values, and the setting is carried out according to the size requirement of the remanufacturing.
In the rear suspension modification of the body-in-white, the required components on the body-in-white include the frame 11, the spring mount, the stabilizer bar beam lug 10, and the coil spring lug 9. During manufacturing, the spring mounting seat is sleeved on the spring mounting seat positioning cylinder 5, the transverse stabilizer bar beam lifting lug 10 and the inclined support are connected and positioned through the transverse stabilizer bar beam lifting lug positioning circular sleeve 3, and the spiral spring lifting lug 9 is connected and positioned with the spiral spring rear lifting lug positioning sleeve 7 through a bolt; then, the frame 11 is installed on a positioning device, firstly, the reference positioning pin 2 and the buffer reference positioning pin 4 are matched with the corresponding position on the frame 11 for positioning, then the spring installation seat positioning cylinder 5 is integrally positioned on the frame 11 by using a bolt, and then the spring installation seat, the transverse stabilizer bar beam lifting lug 10 and the spiral spring lifting lug 9 are welded on the frame 11 for fixing and positioning; thus, the integral frame of the body-in-white is basically positioned and then other positioning parts are connected and installed according to requirements.
