Fig. 11.27. Ways of connection when replacing door panels
|
1) replacement of panels of doors ( fig. 11.27), for what:
— to a welding point soshlifuyta on the strengthening element and a door arch;
— to a soshlifuyta of an edge of the door panel;
— remove the door panel;
— grind and align the interfaced surfaces;
— apply glue on places of a zavaltsovka and on inside of the details of the door panel and a frame of a door put for welding;
— adjust the door panel, put welding clamps;
— bend edges;
— weld on the strengthening element contact spot welding;
— weld edge of the panel a prikhvatochny seam;
— weld electrorivets at a door arch;
— condense edge of a door;
|

|
2) replacement of the strengthening element and threshold ( fig. 11.28), for what:
— replace the strengthening element assembled;
— from the outer side the threshold of a door connects to a Torpedo sidewall under a loop, and at a rack In — at a bend;
— weld continuous seams;
— weld contact spot welding at a doorway and at the lower edge of the panel of a floor;
— weld a threshold electrorivets from below up;
|

|
3) replacement of a rack And (a general view in fig. 11.29) and the strengthening element, for what:
— cut out the damaged part;
— adjust the interfaced surfaces;
— apply welding primer;
— drill openings for electrorivets;
— adjust and fix the strengthening Torpedo sidewall element;
— prepare for welding by electrorivets sites on which it is impossible to execute contact spot welding;
— adjust a rack And;
— cut the edges;
|
Fig. 11.30. Ways of connection of the replaced details
|
— around a loop and fastening of the limiter of opening of a door execute welding by electrorivets;
|
Fig. 11.31. Ways of connection of the strengthening element of the top longeron
|
4) installation of the strengthening element of the top longeron ( fig. 11.31), for what:
— fix the strengthening element of the top longeron;
— weld the strengthening element of the top longeron;
|
Fig. 11.32. The body details forming a rack In: 1 — a sidewall; 2 — a rack In; 3 — the amplifier of a rack In; 4 — the internal panel of a beam of a roof; 5, 6 — internal panels are resistant In (top and lower respectively)
|
5) replacement of knot of a rack In (consisting of five components, fig. 11.32), for what:
— previously cut off the replacing part of a beam of a roof from a rack In;
— cut off the replacing part of a sidewall of a body, so that it could define the provision of a rack In;
|
Fig. 11.33. A way of cutting of a rack In on
the repaired body under welding: And = 30 mm; In = 30 mm; With = 30 mm
|
— on the car remove a rack In (from above — as shown in fig. 11.33, from below — on welding connection);
— establish a rack In inside sidewalls of a body;
— fix a body sidewall on the car;
— weld a rack In on the internal panel of a threshold a prikhvatochny seam;
— remove a body sidewall, leave a rack In on the place;
— cut off both panels at a roof beam, weld a continuous seam;
|
Fig. 11.34. Ways of connection when replacing a rack In
|
— weld the lower section of a rack electrorivets ( fig. 11.34);
— apply glue on a rack In;
NOTE
Before installation of external section of a rack In it it has to be prepared for pasting by epoxy glue.
|
— put a glue layer on the site of 70 mm from a roof beam to 130 mm from fastening of the top loop;
— put a body sidewall over the strengthening rack element In;
— adjust and cut off a joint, weld continuous a seam;
— cut off and weld threshold joints;
— weld the lower part of a threshold on a threshold beam electrorivets;
— execute other welded seams contact spot welding;
— put an internal part of a rack In, weld contact spot welding;
— weld the top joint a continuous seam;
— grind welded seams.
NOTE
Do not forget to rearrange a plate with a carving in a lock clamp cell!
|
PREVENTION
Do not place a welding joint at the stuck together site.
