Parts of a Drill
It is not a secret that all drills They have similarities in their manufacture in terms of the parts that compose them, for those who want a deeper look we will give a detail below:
Here we will make the electric drill cheap, you can see the different types of drills here
Following the references in the image, in point 1 we find the percussion mechanism, thanks to its device, it allows repeated impacts to be produced during the turn in order to punch out stone materials. Its use is optional.
In reference 2, we see a 2-speed mechanism that allows the drill cuts in different materials by configuration.
at point 3 we see the Drill motor shaft. On the left is the cooling fan and to the right the protection for electrical insulation.
the magnetic field it is found at point 4. When the current flows through the copper wire, a magnetic field is created whose polarity depends on the direction of the current.
reference 5 corresponds to the armature. It is made up of a winding whose terminals are on the collector. The magnetic field constantly changes direction, in this way it is alternately driven, thereby achieving the rotation of the drill motor.
at point 6 we see the electronic grader, is a switch essentially based on a thyristor that opens or cuts the circuit that feeds the drill motor. Its principle is that once the voltage has reached the value assigned to it, the semiconductor interrupts the current and restores it again when it has fallen below the chosen frequency. Being electronic, it works practically without current consumption.
the drill collector, it is located at point 7. The armature terminals end in its segments (point 5). Due to its rotation, the different parts of the winding are successively receiving the current. In this way the alternating magnetic field is created.
in reference 8 we find the bearing, the drills require precise and wear-free support. Lubrication lasts practically the entire life of the machine.
at point 9 we can see the drill brushes, are electrodes that transmit current to the collector during its rapid rotation. Carbon is a good conductor and suffers very little wear (they require regular replacement). Springs push the brushes forward and if they are worn, the cable may contact the connector, causing significant damage to the brush. drill.
reference 10 corresponds to drill switch trigger (Depending on the model, they may have speed changes, in the image we can see a case with two speeds). The trigger starts the machine and also allows you to adjust the speed progressively (depending on the model), the button on the right allows you to retain the trigger.
at point 11 we find the rotation regulator allows the electronic capacity to be adjusted by means of the potentiometer
finally the drill housing it is found in reference 12. They are usually based on fiberglass-reinforced synthetic resins, although recently we have detected new trends in the manufacture of this component.
