Description

Impact drill converter

Technical Field

The utility model relates to an impact drill technical field, in particular to impact and bore converter.

Background

Percussion drilling relies on both rotation and percussion to work. A single impact is very mild, but a frequency of 40000 impacts per minute can produce continuous forces. Can be used for natural stone or concrete. When the impact drill works, the adjusting knob is arranged at the chuck of the drill bit, and the common electric hand drill and the impact drill can be adjusted in two modes. However, the impact effect of the impact drill is realized by utilizing the mutual jumping of the gears on the inner shaft, and the impact force is far inferior to that of the electric hammer. It is not suitable for drilling reinforced concrete.

The impact mechanisms of some existing impact electric drills are of a dog-tooth type and a ball type. The ball type impact electric drill is composed of a movable disk, a fixed disk, a steel ball and the like. The movable disc is connected with the main shaft through threads and is provided with 12 steel balls; the fixed plate is fixed on the casing by pins and is provided with 4 steel balls, and under the action of thrust, 12 steel balls roll along the 4 steel balls, so that the hard alloy drill bit generates rotary impact motion and can drill holes on brittle materials such as bricks, building blocks, concrete and the like. The pin is disengaged, the fixed disc and the follow-up disc rotate together, impact is not generated, and the electric drill can be used as an ordinary electric drill.
