Flexible checking implement for large complicated carved punched thin-wall workpiece

Abstract

A flexible detection tool of punching thin wall component with large complicated curve features including two sets of frames being arranged symmetrically and being connected by long foot screws , setting adjustable screw at four edges of frame , applying external through jacked with regulation screw at centre of width edge and a numbers of slats with replaceable scaled pin at length edge , setting two coordinate reference plates in parallel within frame for reading out coordinate value to check whether the value is in the tolerance or not and using filler gauge to check component size.

Description

technical field [0001] The invention relates to a flexible inspection tool for stamping thin-walled parts with large complex curved surfaces, which is suitable for the detection of thin-walled parts stamped with large complex curved surfaces, especially can be widely used in the detection of large covering parts of automobile bodies, such as the detection of complex profiles in space The shape size and position size of the hole, the shape size and hole core spacing of various holes, and the configuration size of some special forming surfaces, etc. Background technique [0002] With the increasing demand for lightweight product structure and beautiful appearance, more and more complex curved surface stamped thin-walled parts are emerging in production, especially stamped cover parts in the automotive industry. Due to the complex geometry of this type of parts, the matching accuracy with the corresponding fittings during welding is relatively high. At the same time, the hole s...

Problems solved by technology

[0004] (1) The shape of the workpiece is often complex and irregular, and it is difficult to locate, support and detect;

[0005] (2) The rigidity of the workpiece is generally poor, and it is easy to cause errors due to deformation during the detection process;

Although the inspection tools for stamping parts have certain advantages in mass production, due to the complex shape, long production cycle and high cost of most of these inspection tools, a considerable part still needs to be imported from abroad, and some special inspections can only be applied to specific parts. Or a certain process link. Therefore, some products need to be equipped with a set of special inspection tools, and the most fatal problem is that a inspection tool can only be applied to a certain part or a specific processing technology. When the surface of the part When the features or dimensions change, it is likely to make the original inspection tools unusable, and it is necessary to redesign and develop special inspection tools
