Abstract
Description
Technical Field
[0001] This invention relates to the field of tubular beam assembly technology, and in particular to a tubular beam assembly tooling. Background Technology
[0002] The automotive instrument panel tube beam assembly is not only a structural component that provides support for instrument panel trim parts and accessories, steering column and airbags, but also an auxiliary fixture and positioning support component in the assembly process of the instrument panel tube beam assembly.
[0003] For example, a patent with publication number CN217142803U, entitled "Automatic Welding Device for Automotive Instrument Panel Tube Beam Assembly," was published on March 1, 2017. It includes a rectangular bracket with drive mechanisms on both sides and a welding robot nearby. Multiple pneumatic clamps are mounted on the top surface of the rectangular bracket. These pneumatic clamps are used to automatically clamp or release the clamps on various workpieces of the instrument panel tube beam assembly. This utility model is stable, reliable, and highly efficient. However, the applicant discovered that when assembling high or low components at the same location on the tube beam, the automatic clamping of the clamps improves the assembly efficiency of the tube beam when assembling low components. However, when assembling high components at the same location, because the high components are larger than the low components, the automatic clamping of the clamps will damage the high components, reducing assembly efficiency.

The positioning element is located between the pipe beam body 2 and the mounting block 22, and the mounting block 22 faces the component support block 17. A mounting hole is provided on one side, through which an extension rod 23 is slidably mounted. A connecting spring 25 connects the bottom of the mounting hole to one end of the extension rod 23.
