Embodiment Construction

[0035] figure 1 A pair of formed sheet metal members constituting a structural component according to the invention are shown prior to assembly. The part comprises first and second profiled sheet metal members 101, 102 to be joined together by welds (see figure 2 ). The sheet metal members 101 , 102 have opposite free ends 103 , 104 arranged to match to form an overlapping portion 100 of a predetermined distance. The part has a generally hat-shaped cross-section in the zone of the overlapping portion 100 . The hat member comprises first and second edge portions 111, 112; 121, 122 extending longitudinally of the component, arranged to engage the first and second side portions 113, 113, 121, 122 of the respective edge portions 111, 112; 114; 123, 124, and a respective central portion 115, 125 arranged to engage said side portions 113, 114; 123, 124. According to the invention, the free end 103 , 104 of the central portion 115 , 125 of each sheet metal member 101 , 102 compr...

Abstract

The invention relates to a structural component for a motor vehicle comprising first and second profiled sheet metal members (101, 102) joined together by spot welding, the sheet metal members having Opposite free ends (103, 104) of the overlapping portion (100). A cross-section of the structural component through the overlapping portion has a hat shape comprising: first and second edge portions (111, 112; 121, 122) extending longitudinally of the component; first and second sides arranged to engage the respective edge portions portions (113, 114; 123, 124); and a central portion (115; 125) arranged to engage the side portions. The free end of the center portion of each plate-like metal member includes at least two protrusions (116, 117; 126, 127) separated by a recess, and the protrusions of the first and second plate-like metal members are joined to the adjacent center portions by welding. part. The invention also relates to a method for manufacturing said component.

Description

technical field [0001] The invention relates to a structural component for a motor vehicle comprising first and second profiled sheet metal members joined together by welding. The present invention is applicable to any type of vehicle including welded sheet metal members, such as automobiles, trucks, buses and construction machinery. Although the invention has been described in terms of automotive applications, the invention is not limited to this particular vehicle type. Background technique [0002] When manufacturing body parts, it is common to assemble larger parts from multiple sheet metal components that are formed in a press and fed to an automated assembly and welding line operated by robotic devices. A robotic device is required to pick out several formed sheet metal components and place them in predetermined positions within the welding fixture. The members are clamped in place and spot welded together by a welding robot. [0003] A problem with this apparatus i...
