AI Technical Summary
Existing drilling machines lack isolation during the drilling process, posing a risk of accidental injury to personnel, and the cutting fluid relies on an external power source for delivery, resulting in a complex structure.
Design a drill press protective cover including an upper support, a lower support, an elastic component, and a protective cover. The elastic component drives the injector to achieve automatic spraying and suction of cutting fluid. The up-and-down movement of the drill press fixed axis drives the protective cover to compress, achieving automatic cooling and lubrication.
It effectively avoids the scattering of chips and accidental contact by personnel during drilling, realizes automatic cutting fluid supply without external power source, simplifies the structure, and improves safety and ease of operation.
