Part inspection tool

Abstract

The invention provides a workpiece gauge. The workpiece gauge comprises a gauge base, a gauge body which is provided with a loop-shaped body and a middle support body, a centering device which is used for adjusting the detection position of a workpiece to be detected, and a positioning device which is used for fixing the workpiece to be detected and is provided with a base, a clamp part, a clamp rod, a positioning connection block, a rotation positioning block and a positioning plate. The base and the positioning plate are fixedly arranged on the gauge base respectively. One end of the clamp part is arranged on the base, and the other end is connected with the clamp rod. The positioning connection block is arranged on the clamp rod. The positioning connection block is provided with a connection groove. The rotation positioning block is pivotally connected with two walls of the connection groove. According to the workpiece gauge provided by the invention, the middle support body can ensure that the workpiece does not collapse in the middle; the centering device can conveniently adjust the position of the workpiece; the centering device can accurately adjust the position of the workpiece; the positioning device clamps and positions the workpiece after position adjustment; and the rotation positioning block works with the positioning plate to accurately position the workpiece.

Description

technical field [0001] The invention relates to a checking tool, in particular to a workpiece checking tool suitable for the outer panel of the automobile bonnet. Background technique [0002] In the welding and manufacturing process of automobile bodies, the accuracy of the body-in-white is the main indicator of the welding process level. High-precision body-in-white can not only improve the assembly of assembly parts, but also improve the quality of the body's appearance gap. At present, in the whole vehicle development process, most of the stamping parts and welding assemblies of automobiles are inspected and accepted by inspection tools to confirm whether the precision of the stamping parts hole and the contour of the surface are qualified to meet the loading requirements. [0003] The design structure of the stamping inspection tool directly affects the convenience and work efficiency of the inspection, and whether the positioning of the parts is in place will also dire...

AI Technical Summary

Problems solved by technology

[0008] (1) Parts of the bonnet outer plate of some models are large in size, and the rigidity of the middle area of ​​the workpiece is usually relatively poor. The structure using convex inspection has the situation that the middle area collapses and sinks, which affects the precision detection of the profile

[0009] (2) The outer plate of the hair cover is an outer plate, and there is no hole in the part, so the hole positioning cannot be used, only the edge positioning can be used

When placing and positioning, it is necessary to manually move and adjust the edge profiles of the adjacent two sides of the outer panel of the hair cover to the reference positioning block 03. It is extremely inconvenient to operate by one person when adjusting the position of the parts, and two people are required to operate, and the adjustment works less efficient

[0010] (3) The outer panel of the hair cover is positioned by leaning against the positioning block 03 through the edge-bending surface of the edge. When the accuracy of the edge-binding surface of the workpiece is unqualified (excessive bending or insufficient rebound bending), The positioning of parts will be positioned and detected based on the unqualified positioning surface, resulting in invalid detection results
