When operation, the drill on the one hand by impact chisel, on the other hand by the drill. This can reduce and avoid the uneven soft and hard work mixed with hard and the drill.
In addition, the electric drill has a clutch, which can automatically skid when the machine is overloaded or the drill bit is stuck, so as to prevent the motor from overload and burning. Impact electric drill according to its impact
The different institutions are divided into two types: large tooth type and steel ball.
The electric drill is composed of electric motor, variable speed system, impact structure (tooth disc clutch), drive shaft, gear, clip head, drill bit, control switch and handle, etc.
Electric drill with the motor as the power source, through the gear speed, drive the drive shaft rotation, and then with the gear, close. The gear is a moving disc clutch, while with the gear
Paired is a still-tooth disc clutch. On the regulating ring of the drill head is the sign of the drill and hammer, the node ring pointer is adjusted to the direction of the bit ", and the dynamic clutch is supported and separated from the static clutch.
At this point, the gear directly drives the drill bit for a single rotation motion. When the pointer of the regulating ring is turned to the direction of the hammer ", the moving clutch is lowered, along with the static clutch
Contact, the electric drill street wheel rotation through the clutch uneven contact surface, produced the impact movement, transmitted to the drill bit to form the impact and rotation.
The above description is an introduction to the working principle of the electric tool electric drill.
