After the working principle of the magnetic drill is electrified, the magnetic drill base generates a magnetic field under the changing electric field, which absorbs the steel structure and plays a fixed role; The other part describes the operation after power-on. For drilling steel structure, the stronger the magnetic attraction, the more stable the body of the magnetic seat drill is when it works. The swing amplitude of the magnetic drill itself determines the higher drilling accuracy of the magnetic drill, so there are many manufacturers all over the world. But the product quality is uneven, because the main function of magnetic drill is to require accuracy.
Magnetic drill is a movable and efficient tool for drilling by using electromagnetic principle to adsorb the drill frame and rotary drilling mechanism on the surface of steel workpiece through magnetic seat. Magnetic drill has two main parts.
The first part: the magnetic seat, as shown in the figure below, is the black cuboid part at the bottom. Its function is to generate thousands of kilograms of magnetic attraction perpendicular to the bottom of the magnetic seat through electromagnetic action after the magnetic drill is electrified, so that it can be firmly adsorbed on the machining surface of the steel plate or structural member, thus playing the role of fixing the machine.
The second part: drilling, which consists of two parts:
1 is the fixed part, which is fixed when drilling, and its main function is to control the motor, such as turning on and off the speed regulating gear, etc.
2 is the leftmost part of the moving part as shown in the figure below, including the left upper black motor, the left middle gray bracket and the left lower drill. By manually rotating the black tripod, the whole moving part moves up and down, thus connecting the drill bit with the steel structure. When the motor start switch is turned on, the rotor in the machine motor rotates at high speed, and the transmission shaft is driven to rotate through the transmission gear set, which drives the drill bit to rotate, and the drill bit cuts the hole at the position where drilling is needed.
Classification and how to distinguish models
A magnetic drill is mainly divided into two categories:?
During the development of magnetic drill, a common magnetic drill, 1 horizontal magnetic drill, appeared. 2 vertical magnetic drill
1, horizontal magnetic drill
In order to adapt to outdoor and aerial work, magnetic drills need to be portable, and the most important feature is portability, so horizontal magnetic drills are not widely used by customers.
2. Vertical magnetic drilling rig
Most customers buy vertical magnetic drills, or magnetic seat drills, iron suction drills, steel plate drills, and so on. Vertical magnetic drills generally weigh more than ten kilograms, and some have handles. Users only need to grasp the handle to work in the field or at high altitude, which is very convenient. This is why it is called portable magnetic drill-this is also the inevitable direction of the development of magnetic drill. Because horizontal magnetic drill is rarely used, generally speaking, magnetic drill refers to vertical magnetic drill, that is to say, vertical magnetic drill is called magnetic drill for short.
