Vehicle engine compartment welding production line

The utility model relates to the technical field of vehicle production and discloses a vehicle engine compartment welding production line. The vehicle engine compartment welding production line comprises a follow fixture system, a fixture switching area, a welding area, a workpiece feeding area and a workpiece storage and conveying area. The follow fixture system comprises a fixture body, a sliding base and a rail device, wherein the fixture body is detachably fixed to the sliding base, the sliding base runs on the rail device, the fixture switching area is communicated with the welding area through the rail device, and the welding area is communicated with the workpiece feeding area through the rail device. The welding area comprises at least one welding robot and at least one workpiece grabbing robot. The workpiece storage and conveying area is arranged on the side adjacent to the welding area. Compared with the prior art, the situation that workpiece feeding and welding must be conducted in a timing sequence is avoided, and takt time is shortened; in addition, the fixture switching area matched with the follow fixture system is added so that fixture replacement can be conducted conveniently to adapt to rapid switching of different vehicle models.
