Problems solved by technology

The torque depends on the force of the pin. Since the pin is under one-way force, there will be a gap between the cylindrical hole and the straight shank, and the lateral force will tend to one side, resulting in increased runout.

Abstract

The invention provides a novel drill bit device comprising a drill bit installation part, a drill bit and a pin. The drill bit comprises a taper shank at one end and a drilling tool at the other end. A groove is formed in the taper tail portion of the taper shank, the bottom face of the groove is an inclined face which inclines to the drilling tool, the drilling bit installation part is provided with a conical drilling hole matched with the taper shank, and the taper shank is inserted into the conical drilling hole; the pin is fixed to the upper portion of the groove, and the lower end of the pin makes contact with the inclined face of the groove and is fixed. The taper shank is arranged at one end of the drilling bit, so the contact face of the coaxial taper shank and the conical drilling hole is increased due to conical design, and torque is greatly improved. Besides, the groove with the inclined face as the bottom face is formed in the taper tail portion of the taper shank, the pin is fixed to the inclined face of the groove, and the reverse locking capacity of the taper shank is improved, so the taper shank is not easy to move, and stability is higher in use.

Description

technical field [0001] The invention relates to the field of drill devices, in particular to a novel drill device. Background technique [0002] Existing drill bit device comprises drill bit mounting part and drill bit, and drill bit comprises the straight shank that inserts drill bit mounting part and drill bit, and straight shank is cylindrical, and drill bit mounting part is provided with the cylindrical hole that matches with cylindrical straight shank, straight shank After inserting into the cylindrical hole, insert the pin into the groove of the straight shank to fix the drill in the drill mounting part. Since the cylindrical hole and the straight shank of the drill bit installation part are all cylindrical structures, there is no friction coefficient between the inner wall of the cylindrical hole and the outer surface of the straight shank during installation, and there is basically no torsion. The torque depends on the force of the pin. Since the pin is under one-wa...
