Problems solved by technology

However, the impact drill uses the gears on the inner shaft to beat each other to achieve the impact effect, but the impact force is far less than that of the electric hammer.
It is not suitable for drilling reinforced concrete
At the same time, the existing impact drill still has technical problems such as complex structure, difficult parts processing, time-consuming and laborious adjustment, and low work efficiency.

Abstract

The invention provides a power structure of a percussion drill. The power structure comprises a shell, a first bearing, a drive rod, a first bevel gear, heavy bobs, heavy bob rods, rotating shafts, second bevel gears, a power rod and a second bearing, wherein the shell is of a regular hexahedron, the first bearing and the second bearing are respectively arranged on two opposite faces of the shell, the drive rod is in rotational connection with the shell through the first bearing, the power rod is in rotational connection with the shell through the second bearing, one end, located inside the shell, of the power rod and one end, located inside the shell, of the drive rod are fixedly connected with the first bevel gear, the rotating shafts are respectively arranged on two opposite faces, parallel to the axis of the power rod, of the shell and are in rotational connection with the shell, and the heavy bob rods are fixedly arranged on the rotating shafts. The power structure has the beneficial effects that the use is more convenient; the power structure has the advantages of simple structure, convenience in repair, low machining cost, high production efficiency and the like.

Description

technical field [0001] The invention relates to the field of metal sheet processing, in particular to a power structure of a percussion drill. Background technique [0002] In the prior art, percussion drills rely on rotation and impact to work. A single impact is very light, but a frequency of more than 40,000 impacts per minute produces continuous force. Can be used on natural stone or concrete. When the impact drill is working, there is an adjustment knob at the drill chuck, which can be adjusted in two ways: ordinary hand drill and impact drill. However, the impact drill uses the gears on the inner shaft to beat each other to achieve the impact effect, but the impact force is far less than that of the electric hammer. It is not suitable for drilling reinforced concrete. Simultaneously, the existing percussion drill also has technical problems such as complex structure, difficult parts processing, time-consuming and laborious adjustment, and low work efficiency. Con...
