AI Technical Summary
Existing anti-penetration detection devices in machining mainly rely on the experience of operators and lack automated damage detection equipment, which makes it easy for novices to damage the detachable worktable with drill bits due to lack of experience.
The system employs a laser rangefinder and a reflector in conjunction with a signal conversion device. The relative height between the drill bit and the detachable worktable is determined by laser rangefinder. When the dangerous height is reached, a warning signal is issued. Combined with the signal changes of the low-voltage positioning screw and the electrical signal receiving board, the controller prompts the operator to slow down or stop pressing down.
It achieves automated anti-penetration detection, preventing damage to the detachable worktable and improving processing accuracy and safety.
