Description

Technical Field

[0001] The utility model relates to the technical field of riveted parts, in particular to a positioning tool used for metallographic connection of riveted parts. Background Art

[0002] With the rapid development of the automotive industry, the use of lightweight materials such as aluminum alloys, magnesium alloys, and high-strength steel is becoming increasingly widespread. Against this backdrop, cold joining technologies, particularly riveting, have gained a significant foothold in connecting vehicle body parts due to their high efficiency, environmental friendliness, and the absence of an external heat source. Riveting, which mechanically presses rivets into the connected parts to form a secure connection, is widely used in the manufacturing of automotive bodies.

[0003] However, with the widespread use of lightweight materials in vehicle body structures, the performance requirements for connection parts are becoming increasingly stringent. Metallographic testing, as an important means of evaluating the microstructure of materials and the quality of connections, is indispensable in the inspection of riveted samples. In the existing riveting test process, samples usually need to undergo precise punching first, followed by riveting operations, and finally metallographic testing. However, under current circumstances, there is no special positioning tooling to assist in riveting samples, and operators usually need to manually hold the samples to perform connection operations. This method not only increases the difficulty of operation, but also due to the lack of precise positioning, it is difficult to ensure the position consistency of each rivet point and the accuracy of the spacing between them. This not only affects the accuracy of the final test data, but may also cause instability and poor repeatability of the test results due to human factors, thereby posing a hidden danger to product quality control. For the problems in related technologies, no effective solution has yet been proposed. Utility Model Content
