Definitions
- the invention relates to a power tool, in particular a Angle grinder, which is a quick-release device for attachment a tool on a spindle having a Clamping flange and a counter flange, between which the tool rotatably under the action of a resilient pressing Can be braced, an actuator that is between a Clamping position and a release position is movable, wherein in the Release the tension between the flange and the Clamping flange against the action of the elastic pressure means is lifted, and one acting on the clamping flange cams, at least in the release position by a motor of the Power tool is set in rotation and at least upon transfer of the actuating element from the clamping position in the release position formed on the actuating element Tread attacks, causing a movement of the actuating element in an axial displacement of the clamping flange implemented is and in the release position with the engine stopped the actuator taking advantage of a between the cam and holding the tread friction force holds.
- a power tool in particular a Angle grinder,
- Such a power tool is known from EP 0 152 564 A2.
- This known power tool has a quick-release device on, with the disk-shaped tools, e.g. Grinding wheels or circular saw blades, quickly and comfortably replaced can be.
- the quick release device comprises to For this purpose designed as a mother clamping flange and a counter flange, between which the disc-shaped tool is strained.
- the clamping flange is on a clamping bolt screwed in the one of the engine of the power tool driven hollow spindle rotation, but in the axial direction is movably arranged.
- the clamping bolt is opposite the Hollow spindle clamped by a spring such that due the spring action of the clamping bolt screwed on the clamping flange is pulled towards the flange.
- the pivot lever is over a shift rod with a switch to turn on the engine connected so that the engine will only be turned on can when the actuator is in the cocked position.
- the power tool should still structurally simple design and inexpensive to produce be.
- this task achieved in that the cam and the tread on each other are tuned that in the release position by Turning on the engine caused rotation of the cam Frictional force between the cam and the tread so reduced that in the release position of the elastic pressure means acted cam the actuator automatically from the Release position moved to the clamping position.
- the invention is based solution principle Consequently, characterized in that for returning the actuator in its cocking position not one produced by the engine Torque, but rather that of the elastic Pressing applied via the cam on the actuator Pressure is exploited.
- the cam As long as the cam is resting, holds the static friction force acting between the cam and the tread the actuator firmly in the release position. Only when the cam is set in rotation when starting the engine is the static friction in the much smaller Sliding over, which is then no longer sufficient, the actuator to hold in the release position.
- the engine causes So only a change in the friction conditions between the cam and the tread; a force transfer from Motor on the actuator, however, takes place - at least in significant extent - not taking place.
- a clamping and a counter flange is here for the rest
- the clamping flange may be in particular to act a conventional nut, the screwed onto the shaft.
- clamping and release position are not present in this case to understand the restrictive sense that so that one exactly defined position should be designated. Under the tension position is rather every position, so also a larger position range, to understand the actuator in which a at least partial clamping of clamping flange and counterflange is achieved. Accordingly, with the release position all positions designated, where no more tension exists between the clamping flange and the counter flange. If So from a movement of the actuator from the Lauerzur Tension position is spoken out, this ultimately means that the actuating element is moved so far until the Bracing has occurred at least partially. This leads in reverse to relieve the components of the quick-release device, so that additional, generated by the engine forces practically no longer cause damage.
- each component which for Power transmission to a formed on another component Surface, here called tread, attacks.
- a special Shape should not be implied by the term cams.
- the Tread itself can be flat, but also curved arbitrarily, the bends also being unwound as gradients Tread can be viewed.
- the tread at least has two sections of different pitch.
- the power transmission to the Actuator is initially low, so that the return movement is slowly introduced into the clamping position. After that increases the slope of the tread, so that the actuator accelerated more.
- This can be, for example be advantageous when the actuator in the clamping position can be locked.
- the speed of the actuator then may be sufficient to the latching resistance to overcome.
- the tread at least two sections of different Surface texture on.
- the tread the rolling surface of the actuator trained, about an axis of rotation rotatably mounted eccentric.
- a preferred embodiment of this embodiment comprises however, the actuator attached to the eccentric shaft Swivel lever, which is around the axis of rotation of the eccentric is pivotable.
- pivot lever has the advantage that so can apply much larger torques than This is the case with a knob.
- Swing lever before pressing the power tool in the To bring clamping position.
- the attachment of the pivot lever on Eccentric can also be done via a freewheel. If that is Actuator is in the release position moves when starting the engine only the eccentric, but not the Swing lever back to the clamping position.
- the eccentricity of the eccentric is between 1% and 20% the largest diameter of the eccentric.
- Such a transverse offset causes when turning on the Motors in the release position of the rotating cam an additional Torque on the eccentric transfers, not on the elastic pressing means, but on the rotation of the cam as such goes back.
- this extra torque that of supports the torque generated by the elastic pressure means or counteracts depends on which side the eccentric offset in the direction of the eccentric axis of rotation is.
- the offset is selected so that the Supported torque generated by the elastic pressure means is to provide additional acceleration of the actuator to achieve.
- the surfaces of the cam and the tread have a Vickers hardness of more than 54, preferably about 64, and a roughness R z between 0.2 microns and 8 microns.
- Such Surface texture may e.g. by hardening and grinding or by rolling (possibly sintered) steel parts achieved become.
- the Motor-driven spindle designed as a hollow spindle.
- the Cam acts on the clamping flange via a pressure piece on which the clamping flange is releasably secured and that in the hollow spindle under the influence of the cam against the action of the elastic Pressing arranged slidably in the axial direction is.
- the cam may be part of the thrust piece or stuck with it be connected, so that every movement of the actuating element directly on the pressure piece and thus on the it attached clamping flange transmits. It is then, however, for it Take care that at least in the cocking position between the tread and the cam remains a small distance, so that it does not interfere with the operation of the power tool continuous friction between the rotating cam and the Tread of the actuator comes.
- the cam is part of a printhead, which in one Sleeve is rotatably mounted and the transfer of the actuating element in the release position against the action of a elastic pressing means that the cam of the print head the tread of the actuator presses axially in Direction of the pressure piece is moved, that the printhead at least indirectly comes in frictional engagement with the pressure piece.
- FIG. 1 A first embodiment of an inventive power tool in the form of an angle grinder is shown in Fig. 1 in total denoted by 10.
- a motor / gear unit 14 Within a housing 12 of the power tool 10 is a motor / gear unit 14, which is shown in dashed lines for clarity.
- the motor / gear unit 14 has an electric motor 16, the motor shaft 18, a pinion 20 for a bevel gear wearing.
- An output gear 22 of the bevel gear is rotationally fixed connected to a hollow spindle 24, the in - in Fig. 1 not - Bearings mounted rotatably about a rotation axis 25 is.
- a counter flange 26 At one of the housing 12 outwardly projecting End of the hollow spindle 24 is formed a counter flange 26, a clamping flange 28 for clamping a tool 30th assigned.
- the tool 30 is shown in the Embodiment to a grinding or cutting disc.
- a quick release device is provided, inter alia the mating flange 26, the clamping flange 28 and an actuating element 31 includes a pivot lever 32. By pressing of the actuator 31 is one between the mating flange 26 and the clamping flange 28 acting stress cancelable.
- the quick-release device has a coaxial in the Hollow spindle 24 arranged pressure piece 34.
- the pressure piece 34 has approximately the shape of a cup and is not by means Guides shown in rotation, but in the axial direction movably guided in the hollow spindle 24. Inside is the pressure piece 34 is provided with an internal thread 36 in the a clamping bolt 40 with an external thread 38 screwed is. The clamping bolt 40 is in turn fixed to the clamping flange 28 connected or integral with this executed.
- the a tight fit between the flange 26 and the Clamping flange 28 causing stress is by a schematically indicated plate spring assembly 42 constructed, which on the one hand at one in the hollow spindle 24 revolving Paragraph 44 attacks.
- On the opposite side supports the cup spring package 42 at the bottom of the pressure piece 34 off. Since the top of the pressure piece 34 at a snap ring 45 strikes, which circulates in an inside in the hollow spindle 24 Groove 46 is inserted, which can from the pressure piece 34, the clamping bolt 40 and the clamping flange 28 formed unit only against the action of the plate spring package 42 in the direction the arrows designated 48 are moved down.
- the pivot lever 32 is fixedly connected to an eccentric 52, which is rotatably mounted on a shaft 53 about a rotation axis 54 is.
- the print head 60 is about the axis of rotation 25 rotatably in a self-lubricating bearing sleeve 62 axially movable added.
- a coil spring 64 With the help of a coil spring 64, the between an annular shoulder 66 of the print head 60 and a Projection 68 of the housing 12 is held, the printhead 60 pressed against the tread 56 of the eccentric 52, so that the print head 60 always in contact with the actuator 31st stands.
- the clamping flange 28 can therefore be in this position of Unscrew the hand from the pressure piece 34, as shown in FIG. 3 indicated by the arrow 71.
- the clamping flange is circumferentially with a knurling 72 provided.
- the Clamping flange 28 not directly on the tool 30. Rather, is on the from the clamping flange 28 and the clamping bolt 40 formed unit rotatably received an intermediate flange 74, the one from a thin disk 76 and one from the middle the disc 76 axially projecting lug 78 is.
- the center of the disc 76 and the projection 78 is a cylindrical Hole through which the clamping bolt 40 is guided.
- the projection 78 has the shape of a regular polygon. This polygonal shape finds its equivalent in the section the hollow spindle 24 below the plate spring package 42, the inside also executed according to polygonal shape.
- the intermediate flange 74 with its projection 78 can be characterized so in this section of the hollow spindle 24 introduce that a Positive locking between the hollow spindle 24 and the intermediate flange 74 is achieved. A mutual rotation of hollow spindle 24th and intermediate flange 74 is then not in the release position possible.
- the clamping flange 28th only lightly tighten until the clamping flange 28 on the intermediate flange 76 strikes because after clamping the clamping flange 28 rotatably held in each case and the plate spring package 42 applied stress practically independent of it is how far the clamping bolt 40 is screwed into the pressure piece 34 is.
- the quick release device now acts the Eccentric 52 so with the cam 58 together that when the actuator 31 in the in Figs. 2 and 3 shown Release position is, the actuator 31st automatically returned to the clamping position is as soon as the engine 16 of the power tool 10 in progress is set. Since in the release position, the print head 60 to the Pressure piece 34 is pressed, transmits in an unintentional Turning on the motor 16, a movement of the hollow spindle 24 on an existing friction on the it rotatably arranged pressure piece 34 and thus on the print head 60 and the cam 58 formed thereon. The thereby caused Rotation of the print head 60 causes the static friction, formed between the cam 58 and the eccentric 52 Tread 56 works, in a much lower Sliding friction passes.
- FIG. 4 shows in solid lines the eccentric 52 as well formed on the pressure piece 60 cam 58 in the in Fig. 1st shown clamping position.
- the pivot lever 32 is the overview not shown.
- the running surface 56 of the eccentric 52 describes in the embodiment shown in Fig. 4 the shape of a circular arc.
- the eccentricity denoted by e i.e. the vertical distance between the center 55 of the Circular arc and the axis of rotation 54 of the eccentric 52 in the clamping position, determines the measure to that with a rotation of the eccentric 52, the cam 58 is pressed down. On a turn of the eccentric 52 by 180 °, this measure is 2e.
- Fig. 5 shows with solid lines the eccentric 52 in the Release position. Since the print head 60 from the plate spring package 42 in the direction indicated by the arrow 84 is pushed upward is acting on the eccentric 52, a torque which in him Direction of the arrow 86 would like to transfer into the clamping position. This torque arises because the cam 58 on the Eccentric 52 exerts a force that is not central to the axis of rotation Exzenters 52 is directed towards. Rather, there is between the Touch line along which the eccentric 52 and the cam 58 touch, and the axis of rotation 54 of the eccentric offset v. By this offset v creates a lever arm, which is addressed to the Torque leads.
- the circular arc diameter is 12.6 mm
- Fig. 6 shows a view from the rear of the eccentric 52, in it can be seen that the eccentric 52 in the direction of the axis of rotation 54 of the eccentric offset from the cam 58 is arranged.
- the Size of this offset is equal to the distance between the median plane 57 of the eccentric 52 and the axis of rotation 25 of the cam 58. Due to this offset, the contact line between the eccentric 52 and cam 58 is no longer symmetrical to the axis of rotation 25th of the cam 58 is arranged.
- the cam 58 Upon rotation of the cam 58 is thereby an additional torque on the eccentric 52nd exerted whose direction depends on whether the cam 58th rotates clockwise or counterclockwise about its longitudinal axis 25.
- the cam rotates 58 in the direction indicated by the arrow 59, whereby the Eccentric 52 in the direction of arrow 61 about its longitudinal axis 54th moved back to the clamping position.
- the conicity of the eccentric 52 can be values of about 0.1 ° to 1 °, preferably about 0.3 °.
- both the eccentric 52 and the pressure pin 60 with the cam 58 made of sintered rolled steel parts whose Vickers hardness in the range of about 64 and the roughness R z in the range of about 2 microns.
- the wear is low due to the high hardness, so that the decisive for the return of the actuator 31 friction ratios between cam 58 and tread 56, on the other hand, the generated during pivoting of the clamping lever 32 stroke of the pressure bolt 60 remain constant over time.
- the plate spring package 42 when the plate spring package 42 generates a compressive force of approximately 3,000 N, the static friction force is approximately 300 N and the sliding friction force is approximately 40 N.
- a rolling surface of such a modified eccentric over the pivot angle ⁇ is applied. It can be seen that the pitch ⁇ 2 of the rolling surface at large pivot angles (release position) is smaller than the pitch ⁇ 1 of the rolling surface at smaller pivot angles (clamping position).
- This design of the rolling surface causes the actuator 31 after the engine is switched on in the release position initially slowly removed from this and then accelerated more. If desired, the final speed can be so great that the actuator 31 finally passes over a latching resistance in an end position in which it is recessed in a recess in the housing 12 of the power tool 10. In the case of larger latching resistances, however, this can be inappropriate, since this possibly requires such a great acceleration of the actuating element 31 that a danger to the user when swinging back can not be completely ruled out.
- the tread 56 On the speed at the automatic swinging back of the Actuator 31 can also by changing the surface texture the tread 56 are influenced.
- the tread between a swivel angle of 0 ° and 60 ° (from the clamping position seen, see Fig. 7) is roughened such that due the larger sliding friction there, the automatic pivoting back movement the actuator 31 braked or at least one further acceleration is counteracted.
- the cam 58 is formed on a print head 60, the first in the course of the pivoting of the actuating element 31 on the Pressure piece 34 attacks.
- the eccentric 52 engages directly on the pressure piece 34. This is then to be done so that it is up the hollow spindle 24 protrudes.
- On the pressure piece 34 may additionally a cam 58 may be formed.
- the cam 58 can but here as well as in the embodiment explained above omitted in the sense that the entire pressure piece 34 or the print head 60 is regarded as a cam.
- Figs. 9a, 9b and 10 is an alternative embodiment for an actuating element 31 shown schematically.
- a slide 100 instead of a pivot lever connected to an eccentric is used here as actuator a slide 100, the bevelled bottom forms a tread 102, the cooperates with a print head 104.
- the printhead 104 has a rounded Top 106, so that the print head 104 as a whole Cam acts.
- the slide provided with a passage 108 100 is so between two indicated only schematically Guided tours 110, 112 that he is in by the arrow 116 can move direction indicated.
- the slider 100 which is shown in Fig. 9b in plan view is in the cocking position.
- the slider 100 is in the release position. Now, if the print head 60 is rotated, so reduced itself, as already described above, between the Top 106 of the print head 60 and the tread 102 of Slider 100 acting frictional force, whereby the print head 60th now the slider 100 back to the clamping position push, as indicated by the arrow 118. Again, the tread 102 of course different Have slopes, as described above for Fig. 7 has been.
