Abstract
The invention relates to a safety drilling device. The safety drilling device comprises a supporting platform and a supporting frame arranged on the supporting platform. A drill bit and a motor used for driving the drill bit are arranged on the supporting frame. Workpiece fixing blocks are symmetrically arranged on the portion, located below the drill bit, of the supporting platform. A workpiece adjustment device is arranged between the two workpiece fixing blocks. The workpiece adjustment device comprises a front sliding block and a rear fixed block located behind the front sliding block. The distance between the front sliding block and the rear fixed block is adjusted through a lead screw. An optoelectronic switch is arranged on the rear fixed block. Floating plates are arranged on the inner sides of the two opposite workpiece fixing blocks through springs respectively. Pressure sensors are arranged on the lower surfaces of the floating plates. An alarm indicator and a control box are further arranged on the supporting platform. A microcontroller is arranged in the control box and electrically connected with the pressure sensors and the optoelectronic switch. The safety drilling device is simple in structure and easy and convenient to operate, the drill bit can be protected in real time, and using is safe.
