Abstract
The invention discloses a twist drill with a locating hole punching function. The twist drill comprises a shell, a twist drill bit and a motor spindle. A cone-shaped body is formed between the front portion and the rear portion of the motor spindle. An elastic body is located between the rear portion of the shell and an impact ring. The motor spindle is sleeved with a middle sliding sleeve which is located between the impact ring and the rear end face of a chuck assembly. A stop dog is arranged at the front end of the middle sliding sleeve. The outer diameter of the middle sliding sleeve is not larger than the inner diameter of the impact ring, and the inner diameter of the middle sliding sleeve is larger than the diameter of the front portion of the motor spindle. The middle sliding sleeve moves along the surface of the cone-shaped body to push the impact ring to compress the elastic body. When the rear end of the middle sliding sleeve coincides with a through hole of the impact ring, the impact ring impacts the stop dog of the middle sliding sleeve, and consequently the chuck assembly drives the twist drill bit to punch forwards. The twist drill with the locating hole punching function can directly complete a whole set of motion such as punching a locating hole, centering and drilling without replacing tools in the using process, so the working efficiency is improved, and the drilling accuracy and the drilling quality can be improved.
