Description

Technical Field

[0001] This utility model relates to the technical field of milling cutter clamping and lifting mechanisms, and in particular to an automatic alignment drilling machine for PP sheets. Background Technology

[0002] In existing technologies, PP sheets require a simple fixture for fixing before drilling, which can easily lead to hole position deviations due to vibration or assembly gaps during processing, resulting in a low product qualification rate. After each drilling, the drilling position still needs to be manually measured and marked, requiring repeated calibration and resulting in long processing time per piece. There is no quick-change mechanism for mold replacement, and machine shutdown and debugging are required when switching to different PP sheet specifications, leading to low equipment utilization. The PP sheet drilling process requires manual control of the drill bit to align with the hole position, making reliable identification, alignment, and continuous processing impossible.
