The coarse guide rod 103 is fixed on the coarse guide rod fixing plate 102 through a bolt and a long mounting hole, and the coarse guide module is adjusted by changing the position of the long mounting hole relative to the bolt; the thin guide module comprises a gasket 104, a round pin 106 and a screw 105, the thick guide rod fixing plate 102 is fixed on the base 101 through the round pin 106 and the screw 105, the thickness of the gasket 104 is adjusted to change the feeding amount of the thick guide rod 103 in the guide direction, the precision is high and stable, and meanwhile, the thick guide rod 103 is additionally welded, so that the accurate landing of a vehicle door is facilitated.
As shown in fig. 5, after the door 7 is wrapped, several points need to be welded properly at the wrapping position, so that the door 7 is prevented from being dislocated after long-term use. For the purpose of improving automation, the edge covering repair welding also uses automatic welding controlled by electric control, and meanwhile, manual welding during equipment failure is considered. The automatic welding mechanism comprises welding tongs 203 and 204, a transformer input end 201, a manual input end 202 and a non-conductive plate 206 for fixing the automatic welding mechanism, wherein the transformer input end 201 is connected with the welding tongs through a cable 205, and the manual input end 202 is used for controlling the working state of the welding tongs.
The welding points after edge wrapping are 4 points in total, because the welding points do not belong to structural welding points, the strength requirement is not high, two welding tongs are used as a group to be connected in series, namely an A group welding tongs 203 and a B group welding tongs 204, each welding tongs 203 and 204 are connected with one cable 205, only the upper electrode is electrified, the welding tongs 203 and 204 are connected together through the vehicle door 7, the lower electrode is fixed and is not electrified, no trace is left on the front surface of the vehicle door 7, and therefore, the inner plate and the outer plate are welded together, and the appearance quality is guaranteed.

The hinge positioning pin seat and the outer hexagonal sleeve of the car door are easy to interfere, and the design of the hinge positioning mechanism 3 only needs to make the pin seat approach to the two positioning holes 702 as much as possible.
Two schemes are selected for avoiding the edge of the vehicle door, namely a swing arm type positioning mechanism is used, and a sliding type positioning mechanism is used. The working principle of the swing arm type positioning mechanism is as follows: when the turnover mechanism works, firstly, the air cylinder is ventilated, the locating pin is extended, then the door hinge is mounted on the locating block and the locating pin, the pressure head is manually closed, then the air cylinder is ventilated to compress the door hinge, and finally, the turnover cylinder is ventilated, so that the whole mechanism is put in place.

The difference between the present example and the swing arm type positioning mechanism is that the hinge 701 is different in the in-out mode, the sliding type positioning mechanism is integrally installed on four sliding blocks 304 of a double sliding rail 303, the sliding rail is fixed on a bottom plate, and also can be directly fixed on the splicing table base 6, the sliding blocks 304 can slide on the sliding rail 303, and the precision and the stability of the mechanism are very high. When the sliding positioning mechanism works, the telescopic pin cylinder 302 is firstly ventilated, the telescopic pin 309 is lifted, the door hinge 701 is mounted on the positioning block 308 and the telescopic pin 309, the pressure head 307 is pneumatically closed, the sliding cylinder 306 is ventilated, the positioning mechanism is pulled in place, and the stop positions of the mechanism are ensured to be consistent each time through the two stop blocks 305. The reciprocating precision of the sliding rail 303 is higher than that of the swing arm type positioning mechanism, and the service life is long. And the sliding type positioning mechanism is more suitable for high-beat production, and has compact and attractive structure.
