Problems solved by technology

However, in the batch positioning welding process of the body-in-white, it is difficult to grasp the rhythm of the body transportation due to the individual control problem by adopting a single conveying method. Especially in the positioning welding station, it is very important to grasp the production rhythm. If Since the conveying rhythm of the body cannot be consistent with the rhythm of the welding equipment, it is easy to cause delays in production and affect production efficiency

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] combine figure 1 As shown, the S1 body bracket supports the body-in-white for transportation: the body-in-white bracket 11 of the body conveying mechanism 1 is lifted upwards under the drive of the liftable lifting guide rail, supports the body-in-white and transports the body-in-white to the welding station.

[0032] S2 sends the body-in-white to the welding station and positions the body-in-white, including the following steps:

[0033] a1 conveyed in place, the body-in-white is lowered, and the side wall positioning column mechanism is turned over to the upright state; a2, the body bracket is detached from the body-in-white and lowered, and the body bracket is retracted: the side wall positioning column mechanism 3 includes a reversible rear positioning column 32, which is placed on the body-in-white During the conveying process, the rear posit...

Abstract

The invention relates to technical field of vehicle body manufacture, in particular to a method for conveying a vehicle body between welding production lines, and further relates to a welding device. The method for conveying the vehicle body between the welding production lines comprises the following steps: S1, conveying a body-in-white to the upper end of a welding station through a vehicle body conveying mechanism; S2, conveying the body-in-white to the welding station, and positioning the body-in-white, wherein the step S2 comprises the following steps that a1, an elevating guide rail of the vehicle body conveying mechanism drives the body-in-white to descend to the welding station, and positioning upright columns of a side surrounding positioning upright column mechanism are in erected states, b1, a side surrounding positioning mechanism descends and is supported by the side surrounding positioning upright column mechanism, and c1, the body-in-white is clamped by fixtures of the side surrounding positioning mechanism and a frame positioning mechanism; S3, welding the body-in-white to be welded at the welding station. The invention further provides the welding device. The vehicle body conveying method disclosed by the invention is better adapted to the production rhythms, and improves the production efficiency. Meanwhile, the welding device further meets the requirements of the vehicle body conveying method on adapting to the production rhythms and improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of vehicle body manufacturing, in particular to a method for transporting vehicle bodies between welding production lines, and also to a welding device. Background technique [0002] At present, the vehicle body conveying method most used by various manufacturers is the single conveying method, that is, a body-in-white uses a single conveying frame to shuttle between the production lines. This has the advantage that a conveying frame can complete the entire production process of a body-in-white. However, in the batch positioning welding process of the body-in-white, it is difficult to grasp the rhythm of the body transportation due to the individual control problem by adopting a single conveying method. Especially in the positioning welding station, it is very important to grasp the production rhythm. If Since the conveying rhythm of the body cannot be consistent with the rhythm of the welding equipment, it ...
