Description

The invention relates to the cartridges of drills or screwdrivers, as well as the cartridges of drilling, turning and other similar machines and is intended to highlight the place of machining parts.

The prior art application for the invention RU 94010417, describing the springless cartridge for the drill. The differences of the stated solution are that:

- The drill chuck, screwdriver or machine with an illumination of the target (or the cartridge with illumination of the target) provides illumination of the area, including inside complex holes where it is impossible to use another illumination located on the instrument handle or on another part of it;

- The cartridge with illumination of the target can have inside a microgenerator or holes that transmit light from a radiation source on the main part of the instrument.

Known patent US 2010053940 describing installed on the instrument illumination, which is located away from the tool holder.

Differences from the stated solution are that:

- The cartridge of the drill, screwdriver or machine with illumination of the target provides illumination of the area, including inside complex holes, where it is impossible to use another illumination located on the instrument handle or on another part of it.

Known patent US 2012242048 describing the drill chuck with rotating relative to each other parts, which allows you to push and slide the tabs of the cartridge.

Differences from the stated solution are that:

- The cartridge of the drill, screwdriver or machine with illumination of the target provides illumination of the area, including inside complex holes, where it is impossible to use another illumination located on the instrument handle or on another part of it;

- The cartridge with illumination of the target can have inside a microgenerator or holes that transmit light from a radiation source on the main part of the instrument.

Known patent CA 2271233 describing a screwdriver with a backlight function, the backlight being installed inside the transparent case and as close as possible to the working tool, and the enhanced backlight function is realized due to the fact that the screwdriver is not electric, and therefore there is no part of the working elements inside the case a screwdriver that does not allow the use of nozzles such as drill chucks in the screwdriver.

Differences from the claimed invention are that:

- The cartridge of the drill, screwdriver or machine with illumination of the target is designed for power tools and provides illumination of the area, including inside complex holes, where it is impossible to use another illumination located on the handle of the instrument or on another part of it;

- The cartridge with illumination of the target can have inside a microgenerator or holes that transmit light from a radiation source on the main part of the instrument.

Known patent JPH 0788712 describing the illumination located on the instrument, the purpose of which is to provide the ability to work with the instrument in the dark without the need to locate a large number of lamps and other lighting devices in the work area.

Differences from the stated solution are that:

- The cartridge with illumination of the target is not intended to illuminate the work area, but to illuminate the target, that is, the drilling site to ensure the most accurate orientation of the tool in space;

- A cartridge with illumination of a target may have a light source powered by the power supply of the instrument (household power, battery, etc.) or the light may have a separate generating device.

The closest solution is patent JPH 1044064 describing an electric instrument with a backlight in which the backlight is removably attached to the front of the case, which brings the backlight closer to the working part of the tool (cartridge), but not enough to work in hard-to-reach places.

Differences from the stated solution are that:

- The cartridge of the drill, screwdriver or machine with illumination of the target provides illumination of the area, including inside complex holes, where it is impossible to use another illumination located on the instrument handle or on another part of it;

- The cartridge with illumination of the target can have inside a microgenerator or holes that transmit light from a radiation source located on the main part of the instrument.

When drilling or other processing of parts (countersinking, boring, grinding, etc.) of complex parts, especially when the place of drilling is inside the hole, between the projections of the body, etc. difficulties may arise associated with the need to accurately hit the place of drilling and illumination of this place for the best hit.

External lighting, as well as lighting located on the handle of the tool can not always help, since the light from them may overlap the protruding parts of the tool. For example, if the drilling site is inside a hole with a diameter of 30-60 mm and a depth of 50-150 mm, then a drill chuck can fit inside the hole, but the light on the tool handle will either not illuminate the hole at all, or will illuminate the edge of the hole, but not the drilling place .

In addition, when it is necessary to drill an element located, for example, on a machine, other protruding parts of the machine and aggregates may interfere with drilling. In such conditions, removable lights will only interfere.

The technical result of the claimed invention is to create a tool holder that could provide illumination of the place of drilling or other work (boring, countersink, grinding, etc.).

The technical result is achieved by positioning the illumination tool chuck, and holes inside the cartridge for light transmission, and in some cases by positioning a light source on the cartridge and inside the cartridge of the generating device.

Special cases of the manufacture of the cartridge with illumination goals are:

- Production of the cartridge without holes of a transparent material;

- Production of the illuminated cartridge with the transfer of electricity to the light source from the main part of the instrument to the rotating cartridge;

Production of cartridges for tools of other types that differ from those described.

The use of the drill chuck, screwdriver or machine with illumination of the target is as follows:

For the operation of the light source (3), electrical energy can be used to work directly with the instrument, or a separate power source can be used, such as a battery, a battery built into the light source module, or a solar battery.

The light source (3) is located mainly on the body of the tool or machine (1) under the chuck (2).

At the same time, in order to allow the rays of light (4) to reach the workpiece (5) in the cartridge (2) light holes (9) are made through which the rays of light (4) pass.

This design avoids the location of additional illumination on the instrument, which can interfere with work in hard-to-reach places and makes it possible to illuminate the place of drilling even inside deep holes, which makes it possible to better orient the instrument in space, improve aiming and avoid poor-quality processing.

Thus, when working, for example with a screwdriver, a person first turns on the light source (3) (by pressing a separate button, pressing the main tool button or in another way) and enters the drilling location. Moreover, at the location of the drilling site inside the recess of the part, a person can press against the tool (in almost all cases except for using the machine) and see the highlighted drilling place. After that the tool is oriented in space in the best way and a person can start drilling or other processing of the part.

Using a drill chuck, screwdriver or machine with target illumination with an energy generator is constructed as follows:

The power generator may include a stator (15), a rotor (16) and / or other parts.

The work of such a generator of energy is based on the fact that in the process of drilling, grinding or other processing of a part, the cartridge (2) rotates relative to the main part of the tool, which allows us instead of the light source (3), the light holes (9) to be placed on the tool body of the stator ( 15), and inside the cartridge, respectively, the rotor (16) of the power generator.

And the energy from the power generator can be supplied via the wire (17) to the light bulb or the LED (18) mounted into the cartridge (2) near the hole for inserting the tool nozzle.

A feature of such a cartridge is the practical impossibility of turning on the backlight, a light bulb, or an LED (18) before starting to process the part, since electric power is generated only during the rotation of the cartridge (2).

Partially this problem can be solved by accumulating electricity and using low-cost voltage LEDs, which will allow the LED to remain on after the preliminary rotation of the cartridge (2).

Design features:

1. Since the light source (3) may not focus the light enough, and the light hole (9) has a certain length, by the time the rays of light (4) reach the machining point on the workpiece (5) the amount of light may decrease and the machining place will not be enough lit. To avoid this, it is assumed that the light holes (9) inside will have a reflective layer in the form of a special insert in the hole or in the form of coating the walls of the hole in the form of silver plating, coating with varnish or other materials. In addition, the light hole (9) must be shaped so as to collect light rays (4) when entering the hole and focus them on the processing site as it leaves the hole.

2. Sometimes the design of the cartridge (2) may be such that some parts interfere with the use of a light hole (9) of the direct type (Fig. 4). In this case, the reflective layer inside the hole allows the use of a curved light hole (11). In it, the rays of light (4) cannot directly reach the part (5) through the cartridge (2), but thanks to the reflective layer, the rays of light (4) can be transmitted from the light source (3) to the workpiece (5) by repeatedly reflecting from the walls of the hole ( eleven).

3. Since the lamps (or LEDs) in the light source (3) have gaps between them in which there is no light, then the following conditions are used to stably maintain the illumination of the target (part processing location):

- Light holes (9) are offset along the axis of the cartridge relative to each other at a different angle. For example, the second hole is offset by 125 degrees relative to the first, and the third hole is offset by 110 degrees relative to the second. It is necessary to take into account the possible imbalance of the cartridge itself.

- If the number of light holes (9) is odd, then the number of lamps in the light source (3) should be even. For example, the number of holes is three, and the number of lamps is seven.

Thus it is possible to continuously illuminate the target through at least one of the light holes (9). In this case, the total number of holes is not limited. This may be one or more light holes.

Similarly, the number of lamps or LEDs in the light source is not limited. This may be a single lamp that works effectively with light reflectors or several lamps.

4. The simplicity of the design allows the use of not only standard and / or fast-clamping chucks, but also any other types of chucks, both with the tightening function of the clamping lugs (8) and with the snap-in function. Moreover, the possibility of using light holes of a curved type (11) removes a number of restrictions caused by different locations of parts in the structure.

5. Target illumination may be required not only when processing the part on the site or on the table, but also when working on the machine. Therefore, it is envisaged that the technology can be used, for example, in the chuck of a drilling machine, a milling machine, or in a lathe spindle. If the technology is used in the spindle of the lathe, then there are some restrictions on the use associated with safety, however, it should be borne in mind that the technology in this case increase the efficiency and accuracy of work. Moreover, as in the case of a drill or screwdriver, the light source (3) can be located under the spindle of a lathe in which light holes (9) are present. Also in this case, the transfer of energy from the machine to the spindle on which the light bulb (18) is installed or the use of a power generator can be used.

6. In addition to new samples of the instrument, a cartridge with a target illumination function may be required on older samples of the instrument. In this case, the design can be completely removable. That is, the cartridge (2) does not have special details that would connect it with the tool. Directly to the instrument only the light source is mounted (3). If the light source (3) will have its own energy source, that is, it will not be powered by a drill, screwdriver or machine, then it can be transferred together with the cartridge to another tool if the design of the tool allows. In this case, not only the stationary installation of the device is realized, but also the possibility of using a removable device.

Similarly, the possibility of a removable device can be realized in the relationship of the cartridge with target illumination with the function of generating energy. If the stator (15) or another element fixed on the tool body can be moved from the body (1) of one tool to another tool, then the rotor (16) and other parts are located directly in the cartridge (2) and are rearranged with it. There may be a limitation if the body of one tool allows you to install a light source (3) or a stator (15), and the body of another tool may not allow this.

7. The generating device may differ from that described above, since other designs of generating devices are possible. This may be a stator (15) and a rotor (16), and / or a piezoelectric element generating electricity, in addition, it is possible to change the design of the described generating device in such a way that instead of the rotary motion of the rotor the reciprocating motion of the core inside the electrical windings will be used. As well as other types of generating devices.

8. In addition to direct power transmission to a light bulb or LED from a generating device, it is possible to use a power transmission system from the instrument to the cartridge using contacts, one or more of which are movable relative to the others.
