Example Embodiment

[0038] Example

[0039] As attached Figure 15 As shown, the door guard panel welding structure of this embodiment includes a door guard panel body; the door guard panel body has a plurality of mating plane parts that cooperate with the welding columns, and the mating plane parts are provided with main positioning Holes, auxiliary positioning holes, pre-installation holes and general welding holes. Before ultrasonic welding, welding columns are inserted into the main positioning holes, auxiliary positioning holes, pre-installation holes and general welding holes, and the welding columns include an integrally formed base and a hollow column body located on the base, After plugging, the base is located at the bottom of the mating plane part, and the hollow column body is at the upper part of the mating plane part. Figure 1-3 The general welding position is shown. The distance between the welding column 1 and the general welding hole on the mating plane 2 is 0.5-1 mm. Figure 4-6 ...

Abstract

The invention relates to a door backplate welding structure, and belongs to the technical field of automobile assembly parts. The door backplate welding structure includes a door backplate body and welding columns; the door backplate body is provided with a plurality of cooperative plane portions which are matched with the welding columns, and primary locating holes, auxiliary locating holes, pre-mounting holes and normal welding holes are formed in the cooperative plane portions; and welding columns are in inserted in the primary locating holes, the auxiliary locating holes, the pre-mountingholes and the normal welding holes in a connecting mode, and welding columns include bases and hollow column bodies which are located at the bases. The door backplate welding structure uses equal sized welding columns for a primary locating structure, an auxiliary locating structure and a pre-mounting structure, the structures are simple, and the installation is reliable; and not only can the welding assembly precision be effectively guaranteed, but the welding efficiency can be improved, the welding quality is improved, and the structures are unify and attractive after welding.

Description

technical field [0001] The invention relates to the technical field of automobile assembly parts, and more specifically, the invention relates to a door guard plate welding structure. Background technique [0002] Among auto parts, especially in door guard accessories, the ultrasonic welding connection is very common. The welding structure is simple and reliable, and the strength after welding can also ensure the installation state of the parts. Ultrasonic welding is an indispensable and important connection form in the design of door guards. Not only between door guard accessories, but also in other parts, ultrasonic welding is often used for connection and fastening. In the prior art, the welding of the door guard plate needs to be realized by adding cross ribs to cooperate with round holes, and adding cross ribs to cooperate with oblong holes, and the welding cost is high and the efficiency is low. Contents of the invention [0003] In order to solve the above-mentione...
