Description of drawings
Below describe the present invention in detail by the embodiment shown in the accompanying drawing.Accompanying drawing is represented:
Fig. 1 is according to a schematic isometric of the hand-guided grinding of first embodiment,
Fig. 2 is according to a side view signal, that part is dissectd of the hand-guided grinding of second embodiment.
The specific embodiment
Summarily represent an electric tools that is hand-guided grinding 10 forms among Fig. 1, it has a housing 11, and the upper area 12 of the longitudinal extension of this housing is shaped to the handle form and has an electric switch 13 at its leading section.In this embodiment, hand-guided grinding 10 is configured the milling drum that can be used for seamed edge and bight, and it has the grinding dish 14 of a general triangular at downside.Grinding dish 14 for example has an intermediate plate 15 on a gripper shoe 9, the latter's downside is provided with a thread gluing layer (Klettschicht) 16, is used for removably fixing a unshowned abrasive sheet.With the suitable ground of the shape of the grinding dish 14 of general triangular, the lower area 17 of housing 11 also has the profile of general triangular and forwardly has a corresponding front tip part 20 or angle in the zone 18 above the front tip part 19 of grinding dish 14 or angle, and the latter for example carries out the transition in the upper area 12 by a recessed arching portion 21.
Held a unshowned motor together with transmission device and driving shaft in housing 11, this driving shaft drives 14 vibrations of grinding dish.Housing 11 also comprise one be used for to motor power supply, also unshowned power supply, the especially power supply of lithium-ions battery form.This is common general knowledge by battery-driven hand-guided grinding 10.
The characteristics of this hand-guided grinding 10 are, are provided with a lighting device 30 in the front area 18 of housing 11, for example arching portion 21, and it is used to illuminate the working region of hand-guided grinding 10.Lighting device 30 is set on the housing 11 or in this housing and here above grinding dish 14, and is downward-sloping forward specifically, illuminates the front and the other working region of side that are positioned at tip 19 thus particularly well.Particularly advantageous is that lighting device 30 is by the same power supply power supply of motor being supplied with electric current.Hand-guided grinding 10 is simple, compact, light especially and cost is favourable thus.In the case, lighting device 30 is connected by unshowned electric lead on the circuit board 11 that is contained in the housing 11, and this circuit board is arranged on the right back end of Fig. 1 hand-guided grinding 10 and is not shown.Electric lead is guided front area 18 and the lighting device there 30 into from this circuit board.
Particularly advantageous is that lighting device 30 has at least one light emitting diode (LED) 31.This at least one light emitting diode 31 is made up of the white light-emitting diode of a superbright in an advantageous manner, this light emitting diode has an angle of radiation, although this angle of radiation and toolroom machine for example can be in about 30 ° to 90 ° scopes in this routine hand-guided grinding 10 relatively according to the distance of working face and different.Show to have a hand-guided grinding 10 shown in especially a light emitting diode 31 is suitable for particularly well with battery-driven motor; Because in the case, based on existing lithium-ions battery, the required usually small voltage between 5V and 15V of light emitting diode exists as the output voltage of this battery.
Though a light emitting diode 31 only is shown in the example of Fig. 1, can understand equally, also a plurality of light emitting diodes (LED) can be set on this position, they are along a row and/or become arcuation ground, layout circlewise for example there.These light emitting diodes for example are installed in the maintenance lath for example made of plastic and correspondingly are installed on the hand-guided grinding 10 in the case.
This hand-guided grinding 10 that is provided with lighting device 30 also has many-sided advantage.Can very well illuminate by this lighting device 30 will be with the working face of this hand-guided grinding 10 processing.When grinding on bight and seamed edge or other position that is difficult to see clearly, can be the light that these positions produce q.s by this lighting device 30, can when grinding bight and seamed edge, accurately finish the grinding task thus.In some grinding work, for example on the window frame zone of incident daylight and have in the grinding of brighter/dark contrast, be restricted to the sight line of working face, at this, based on good illumination, can carry out accurate and grinding easily by lighting device 30.For the grinding work below jut, covering such as plywood etc., this lighting device 30 also provides sufficient light, so that these grinding work also can accurately be carried out.Can very accurately work by this lighting device 30 in addition, for example pointwise Precise Grinding, transition portion finish ground are avoided grinding step etc. simultaneously.Lighting device 30 makes the user of hand-guided grinding 10 can very well see the workspace, although for example there is the abrasive dust that gathers still can see the mark or the line that may exist well, even they are covered by the dirt bits at least in part.Also can get rid of such danger: when the grinding dish 14 with hand-guided grinding 10 guides or is registered on the seamed edge, damage high side, position, because also can realize good illumination here by lighting device 30.In addition by under illumination, observing the wearing and tearing that work progress can in time be determined abrasive sheet, for example wearing and tearing at abrasive sheet edge.Advantage also has, and can meet the destination based on good illumination and siphon away grinding dirt bits.Making the operate miss that may occur in the grinding process be discovered immediately and make by the illumination of 30 pairs of working regions of lighting device not only can realize standard grinding, work and can be ground to last angle and can be with the recessed or protruding shape of oval grinding tongue grinding with the grinding tongue always with the good grinding effect.
In second embodiment shown in Figure 2, for using identical label, so that thus can be with reference to explanation, to avoid repetition to first embodiment corresponding to the part among first embodiment.
Hand-guided grinding 10 shown in Fig. 2 is configured to have the triangle milling drum of the grinding dish 14 of general triangular.Include a motor 22 in housing 11, it drives a driving shaft 24 by a transmission device 23, and this driving shaft is provided with a counterpoise 25 and drives 14 vibrations of grinding dish with its bottom among Fig. 2.Be provided with a lighting device 30 that is used to illuminate the working region in the front area 18 of housing 11, this lighting device has at least one light emitting diode (LED) 31, and it remains in the housing 11 replaceably and is arranged to downward-sloping forward.The structure and the characteristics thereof that also are suitable for this lighting device 30 above in conjunction with the explanation of Fig. 1, especially consequent advantage.
In second embodiment of Fig. 2, lighting device 30 is not by the power supply power supply that is used for motor 22 power supplies, but is powered by the power supply 26 of oneself.This power supply has the magnet 28 that rotate, that driven shaft 24 drives in coil 27, respond to an electric current by this magnet in coil 27, is used for illumination apparatus 30 power supplies.Coil 27 is electrically connected with lighting device 30, especially described at least one light emitting diode 31 by electric lead 29.
This power supply 26 be simple, save position, light and cost is favourable.When driving shaft 24 rotated, magnet 28 rotated thereupon, and induction generation electric current in coil 27 thus, this electric current are enough to make lighting device 30, especially described at least one light emitting diode 31 luminous.When motor 22 energisings, lighting device 30 is also connected simultaneously.
In another embodiment of hand-guided grinding 10, this hand-guided grinding is with the line voltage work of 100V to 240V, can use the power supply of an electrical source importing device as lighting device 30, this electrical source importing device is installed in the housing 11, but requires corresponding position there.In contrast to this, second embodiment shown in Fig. 2 has saved electrical source importing device and the installation that brings problem sometimes in housing 11 thereof.
