Description

Technical Field

[0001] This utility model relates to the field of marking technology, and in particular to a marking fixture for a nut plate. Background Technology

[0002] In the commercial vehicle manufacturing sector, nut plates are critical connecting components, and the clarity and permanence of their markings are essential for product traceability and quality control. A brand's newly designed nut plate product in China involves a manufacturing process including sawing, machining, marking, electrophoresis, and anti-corrosion packaging. The marking process presents a unique challenge: the markings must remain clearly visible after electrophoresis. Acceptable marking methods are laser or stamping; however, laser marking is prone to blurring after electrophoresis, necessitating stamping. The markings contain 15 characters (letters and numbers) with strict tolerance requirements for their placement. Simultaneously, the product's outline must not deform after marking, and the threaded holes must meet assembly requirements. Currently, there is no mature development experience for similar products, either domestically or internationally, and traditional marking methods cannot simultaneously meet the requirements for depth, clarity, efficiency, and deformation resistance. Therefore, a dedicated marking fixture is urgently needed to solve these problems. Utility Model Content
