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 abroa

Embodiment Construction

[0024] Such as figure 1 As shown, the present invention is made up of two sets of symmetrically arranged frames up and down. The uppermost and the lower ends are two "well" shaped frames, i.e. the upper frame 12 and the lower frame 21. Eight of the two frames There is a through hole at the end point, and the upper frame body 12 is fixedly connected with the lower frame body 21 with the hex nut 3 through the through hole with a long-legged screw rod 1 with a handle 2 . There are two square blind holes in the center of the two width directions of the upper and lower "well" frame bodies, which are respectively used to fit the internally threaded sleeve 20 with a square prism at the bottom and a hexagonal prism in the middle. The double-ended adjusting screw 17 of the body penetrates into the middle of the upper and lower two internally threaded sleeves 20; threaded holes are evenly and symmetrically opened in the middle of the two long sides of the upper frame body 12 and the low...

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...
