Abstract

A spindle automatic feed mechanism of drilling machine with self-adaptive electromechanical transmission comprises a head housing assembly, an elevating axis assembly, and a large motor. The head housing assembly comprises a spindle assembly, a spindle sleeve, a reducing motor, a first worm, a first worm gear, and a turbine shaft. The elevating axis assembly comprises an elevating axis, a first cylindrical gear, a second cylindrical gear, a left end face clutch gear, a right end face clutch gear, and a cam. A second v-belt pulley is connected to an upper output end of the large motor. The invention adopts the independent electromechanical transmission mechanism to drive a spindle system to realize spindle automatic feeding, the feeding speed is fixed. Every rotational speed of the spindle has a suitable self-adaptive spindle feed amount correspondingly.
