Description

Technical Field

[0001] The utility model relates to the technical field of train manufacturing, in particular to a window frame drilling pre-positioning device. Background Art

[0002] During vehicle body assembly, the side window frames require the corresponding window glass to be installed. The window glass is mounted and positioned on the frame using four mounting brackets. While the upper and lower mounting brackets are drilled upon arrival, the left and right sides are not. Therefore, during on-site window frame assembly, holes must be drilled on both sides to accommodate the left and right window glass position-limiting brackets. However, current window frame drilling operations lack dedicated auxiliary devices to locate the holes, severely impacting work efficiency and product quality. Existing window frame drilling operations require manual measurement, marking, and marking of each hole, resulting in poor efficiency. Summary of the Invention
