Description

Technical Field

[0001] This utility model relates to the field of mechanical processing and production technology, and in particular to a laser hot melt tapping composite machine. Background Technology

[0002] Honeycomb steel panels are sheets of material made by firmly bonding two steel plates to both sides of a thick honeycomb core material; they are also known as honeycomb sandwich structures. In engineering applications, the secondary processing of honeycomb steel panels is a key factor in determining their functionality. A typical processing flow includes three core steps: laser cutting to create precise cuts at predetermined locations; hot-melt drilling to create through channels in the honeycomb core layer through a high-temperature melting process; and tapping to create threads on the hole walls to meet the installation requirements of fasteners.

[0003] The current mainstream machining method disperses the three processes across different workstations. This discrete machining system has revealed significant technical shortcomings in practical applications. The workpiece undergoes multiple disassembly-positioning-clamping cycles between laser cutting, hot-melt drilling, and tapping processes. The systematic errors generated by each repeated clamping exhibit a non-linear cumulative effect. Experimental data shows that after three clamping cycles, the positioning error of the reference surface can reach 0.12-0.25 mm, far exceeding the 0.05 mm threshold requirement for precision assembly. This error amplification phenomenon stems from the coupling effect of multiple factors: mechanical wear of the clamping fixture leading to reference surface offset, microscopic deformation caused by differences in clamping forces between different processes, and differences in the thermal expansion coefficient of materials due to environmental temperature fluctuations.

[0004] Although traditional clamping technology performs stably in basic applications, its inherent defects are particularly prominent in high-precision, multi-process scenarios such as laser cutting, hot melt drilling, and tapping composite machines: the direct contact between the rigid floating jaws and the workpiece creates mechanical impedance matching, resulting in processing vibrations that are transmitted to the machine tool. At this time, the workpiece and the machine tool resonate. Although the floating jaws fix the workpiece, this vibration can still cause the workpiece to shift, leading to problems such as deviations in the processing position. Utility Model Content
