Positioning mechanism of edge covering assembly detector

Abstract

The invention discloses a positioning mechanism of an edge covering assembly detector. The positioning mechanism comprises a support, an installation block, a positioning block and a push rod of a preset length, wherein the installation block is arranged at one side of the top of the support, the positioning block is arranged in the installation block, and the push rod is arranged at one end of the positioning block. The installation block is internally provided with a U-shaped groove which penetrates through the installation block, the top of the installation block is provided with scales along the edge of the U-shaped groove, the positioning block is installed in the U-shaped groove in a sliding manner, and the top end of the positioning block is provided with graduation lines at a preset position. An open groove is formed in the end portion of the positioning block, the two ends of the push rod include stepped shafts respectively, the stepped shaft at one end is fixed in the open groove, and the stepped shaft of the other end extends out of the U-shaped groove and makes contact with the edge covering assembly. The positioning mechanism can accurately detect whether an edge covering assembly is qualified and whether loading requirements are satisfied, avoids unqualified components from entering the market, and is simple in structure and convenient to install.

Description

technical field [0001] The invention belongs to the field of measuring devices for inspection tools, in particular to a positioning mechanism for inspection tools for hemming assemblies. Background technique [0002] At present, in the development process of passenger cars, most of the four-door and two-lid hemming assemblies (that is, front and rear door hemming assemblies, hair cover hemming assemblies and trunk lid hemming assemblies) are inspected and accepted by inspection tools. To confirm whether the accuracy of the assembly and the contour of the surface are qualified and whether it meets the loading requirements. After the edge wrapping assembly is finished on the inner and outer plates, the edge positioning is the R angle (arc fillet) part, the positioning state of the assembly inspection tool is designed according to the theoretical state during design, and the stamping parts are in the There are always errors after welding hemming, and it is impossible to achiev...

AI Technical Summary

Problems solved by technology

The positioning scheme of the prior art is adjusted by the push rod and the thread, and there will always be a certain deviation from the theoretical state after the assembly is hemmed. This mechanism cannot know the offset of the welded assembly relative to the theoretical state. , it is impossible to ensure whether the hemming assembly is qualified and whether it meets the loading requirements
