Abstract

A method of assembling components of a vehicle is provided that includes locating a node ( 20 ) relative to an adjoining component ( 22 ), measuring at least one geometrical feature of the node or the adjoining component, 3D printing an assembly adjustment member ( 24 ) based on the measuring, and placing the assembly adjustment member proximate at least one of the node or the adjoining component. The assembly adjustment member is configured to allow relative movement between the node and the adjoining component for subsequent processing operations.

First claim

What is claimed is:

1. A method of assembly comprising:
fabricating a node with at least one tooling feature;
locating the node relative to an adjoining component;
placing a component blank onto the node and locating the component blank with the at least one tooling feature;
measuring at least one geometrical feature of the node or the adjoining component;
3D printing an assembly adjustment member onto the component blank based on the measuring, the assembly adjustment member being separate from the node; and
placing the assembly adjustment member proximate at least one of the node or the adjoining component,
wherein the assembly adjustment member is configured to allow relative movement between the node and the adjoining component for subsequent processing operations.

2. The method according to claim 1 , wherein the 3D printing is performed in-situ with the method of assembling.

3. The method according to claim 1 , wherein the assembly adjustment member is disposed between the node and the adjoining component.

4. The method according to claim 1 , wherein at least one of the node and the adjoining component are formed by a 3D printing process.

5. The method according to claim 1 , wherein the node further comprises a tapered outer geometry configured to provide additional relative movement between the node and the adjoining component.

6. The method according to claim 1 , wherein the subsequent processing operations are selected from the group consisting of an electrophoretic coating (E-Coat) process, painting, and surface coating processes.

7. The method according to claim 1 , wherein a plurality of nodes and a plurality of adjoining components are measured, and the 3D printed assembly adjustment members are paired with closest mating geometries of nodes and adjoining components,
wherein the assembly adjustment member is configured to allow relative movement between the node and the adjoining component for subsequent processing operations.

8. The method according to claim 1 , wherein the node is an organic node that is optimized for design load conditions and is formed by a 3D printing process, the node defining at least one receiving portion and an outer geometry that is configured elastically, and up to plastically, deform for fit-up of the node to the adjoining component.

9. The method according to claim 1 , wherein the 3D printing is performed offline and the assembly adjustment member is prefabricated.

10. The method according to claim 9 , wherein the assembly adjustment member is selected from a library of standard assembly adjustment members.

11. The method according to claim 1 , wherein the adjoining component defines an insert that is disposed at least partially within a hollow space of the node.

12. The method according to claim 11 , further comprising mechanically securing the adjoining component within the node after the subsequent processing operations.

13. The method according to claim 11 , wherein the hollow space of the node is at least partially filled with an adhesive after the subsequent processing operations.

14. The method according to claim 13 , wherein the adhesive is injected into the hollow space of the node through an injection port.

15. A method of assembly comprising:
fabricating a node;
locating the node relative to an adjoining component;
placing a component blank onto the node;
measuring at least one geometrical feature of the node or the adjoining component;
3D printing an assembly adjustment member on the component blank based on the measuring; and
placing the assembly adjustment member proximate at least one of the node or the adjoining component,
wherein the assembly adjustment member is configured to allow relative movement between the node and the adjoining component for subsequent processing operations.

16. The method according to claim 15 , wherein the assembly adjustment member is selected from a library of standard assembly adjustment members.

17. The method according to claim 15 , wherein the node has at least one tooling feature, wherein the component blank is located onto the node with the at least one tooling feature.
