Drilling machines are special devices, used in working with wood, metals, plastic, etc.. D. With their help you can perform a large number of functions, which would take a lot of time to use when using improvised means. The design of the machine is nothing complicated, as well as the collection, therefore it is quite possible to collect it with your own hands. in addition, such a homemade device in many cases differs little from standard factory models.
General Information
Drilling machine is most often used for drilling parts. He does his job, using the power of the electric motor, which, rotating your shaft, transmits force to the main rotating element of the unit or spindle. Attach to the latter:
- adapters;
- drills;
- cartridges;
- bushings.
In essence, such a machine is a mechanism, fixed in a stable position, designed for drilling various parts for a long time.
Man, working on such a unit, it is only necessary to substitute details in time, adjust their position and control the operation of the machine. It is much more convenient, than if I had to work manually. in addition, high accuracy cannot be achieved as a result of manual drilling. The point is, that a person needs to choose the right angle of effort. An error of a few degrees can be fatal. And not everyone is able to withstand work at this pace.
Quite another matter, when a drilling machine is used for work. In this case, you only need to fix the part in the vise, then start the machine. All the following steps will not take much time and effort.
Design features of the machine
That it was easy to cope with work, need to understand, what makes up the unit together with its components.
A conventional drilling machine consists of the following parts:
- bed;
- holders under the working mechanism;
- additional elements (nuts, drills, cartridges, bushings);
- the lens;
- handles of rotation of mechanisms, force transmitters, etc.. d .;
- main frame guides;
- working mechanism;
- shock absorber;
- Power Supply.
The design itself is nothing complicated. As a basis the bed fastens. If you consider a desktop sample (and homemade machines are often desktop), then the frame in this case will be used as a fixture for devices such as vices, and as a stabilizing factor, as well as the basis. The main frame is attached to the frame, on which the whole mechanism will be kept. A holder is attached to the frame, shock absorber and additional elements. In the case of an adjustable shock absorber, a handle is connected to it.
The engine of the machine is attached to the main frame, to which then bring the spindle and adapters. The power supply is available only in such models, the engine in which is installed separately, and it is not able to take the load, coming from the household network.
Selection of necessary elements
Assemble a homemade unit from improvised means, therefore, the choice of structural parts should be given special attention.
First of all you need to choose the material for the frame. It should be only metal. A heavy plate may fit, in which holes are drilled, necessary for future vices and clamps. It is best to buy a mobile or remove an old frame from a used desktop machine.
The main stabilizing rail is made of a corner or channel, not less than the thickness 3 mm. This part does not give vibrations and backlash and is able to withstand the load. The holder for the working mechanism is also made of steel. In this case, the choice depends on the engine, which will be used.
The main point in such a scheme of the machine with his own hands is, that for assembly of the unit apply details from a steering rack of the car, since it is compact and has unique capabilities.
During rotation, the steering rack raises and lowers the mechanism, which is attached to it. Such manipulations should be carried out very carefully, up to one millimeter. Many steering racks have the ability to reduce or increase voltage, which leads to the possibility of fine-tuning.
It is best to remove the handles from ready-made machines, however, they can be made with your own hands. In the same way you can use production bushings and cartridges, because it's easy to get them.
Selection of the working mechanism
This element in the drilling machine with his own hands is not only traditional, but also much simplified. In this case it is a question of replacement of the power supply unit and the engine ready by a drill or the unit, which is used for drilling metal, concrete, etc.. D. Such portable tools have almost the same dimensions, as an ordinary drill. However, they are so powerful, that can drill metal without serious resistance.
The drill should be attached with a small number of brackets, before fixing it in the right position. It must be located perpendicular to the base of the unit.
The use of a drill in the scheme of the machine from the steering rack is considered better. At the same time, much less time will be required to assemble the unit. You can also install an induction motor from any electrical appliance. In this case, the assembly takes much longer. But the technology will remain the same.
Making a machine from the steering rack with your own hands
The technology of assembling a drill with your own hands from the steering rack includes the following steps:
- make installation of a bed in the necessary position;
- grooves and openings are drilled in the bed, which will be used for future vices;
- mount the main rail from the channel or corner;
- attach the steering wheel to it;
- after that handles are mounted to it and its course is regulated;
- on the upper part of the steering set mounts for the drill;
- carry out installation of a drill in necessary position, adjusting the angle of its inclination;
- finally fix the working mechanism;
- bring all the wires, tighten the bolts, test the system.
So, there is nothing complicated about it, to make a drill from the steering rack with your own hands. Quite a lot the process is simplified due to that, using ready-made solutions, such as steering and drill. You just have to be more discriminating with the help you render toward other people, that the assembly of the unit is performed correctly.
