Description

Technical Field

[0001] The utility model relates to the technical field of automobile sheet metal inspection, in particular to an auxiliary tooling for automobile sheet metal inspection. Background Art

[0002] The sheet metal used in the automotive industry will generate internal stress after production due to the high pressure it is subjected to during stamping. Under the action of this stress, the edge of the sheet metal will deform upward or downward, causing the edge of the entire sheet metal to take on a wavy shape.

[0003] Currently, after automobile sheet metal parts are stamped out, they need to be inspected for edges using three coordinates. However, when the inspection head on the three coordinates is moved along the edge of the sheet metal part for inspection, waves appear on the edge of the sheet metal part under the action of stress. Therefore, when inspecting, the inspection head will cause false detection or missed detection at the location where the waves appear on the sheet metal part. At this time, it is necessary to manually press the sheet metal to flatten the waves on the sheet metal to cooperate with the inspection. On the one hand, this inspection method is not efficient and requires manpower cooperation and multiple inspections at the waves to ensure accurate inspection. In addition, when the sheet metal thickness is greater than 1mm, it cannot be flattened by manpower, so the labor intensity for the staff is relatively high.

[0004] Therefore, there is an urgent need for an auxiliary tooling for automobile sheet metal inspection, which can be used to assist the three-coordinate inspection of automobile sheet metal edges, improve the inspection efficiency and reduce the labor intensity of staff.

[0005] Three-dimensional (3D) testing involves using a 3D coordinate measuring machine (CMM) to inspect and measure the form and position tolerances of a workpiece. This process determines whether the workpiece's errors are within tolerance. This is also known as three-dimensional (3D) measurement. With the rapid advancements in the modern automotive, aerospace, and machining industries, 3D testing has become a common testing method. CMMs are no longer a luxury item. Foreign and multinational companies, in particular, emphasize third-party certification. All products leaving the factory must be accompanied by a test report from a qualified testing agency. Therefore, 3D testing is becoming increasingly important in the manufacturing industry. 3D testing is also sometimes used in reverse engineering. This involves collecting and mapping the spatial geometry and three-dimensional data of an object, providing point data, and then using software to construct a 3D model. Utility Model Content
