Definitions
- the invention relates to a power tool, in particular circular saws and the like a motor mounted in a housing that drives a hollow spindle and a quick release device to hold a tool
- the quick release device a has in the hollow spindle coaxially displaceably mounted clamping spindle, which by a elastic element is axially clamped and by means of one facing away from the tool Arranged end of the clamping spindle, clamping lever, which has an axis of rotation at one end has and between a clamping position in which the tool on the hollow spindle rotatably is clamped, and a changing position, is movable and the tool between a clamping flange that can be attached to the tool-side end of the clamping spindle and the Hollow spindle is mounted braced.
- Power tools of the type mentioned above have a quick-action clamping device in order to to enable manual changing of a tool.
- No auxiliary tool is required in the case of clamp tensioning devices to relax or to relax.
- a wrench as an auxiliary tool, for example the tool switch.
- the quick release device can be used, for example a clamping lever can be operated, for example to change the tool.
- Such a power tool is known from DE-C2-4336620, with one in one Housing mounted motor that drives a hollow spindle and a quick release device for holding a tool.
- the quick release device has one in the Hollow spindle coaxially displaceable clamping spindle by an elastic element is axially clamped.
- the quick release device is between a Clamping position and a change position adjustable.
- the tool is in the clamping position between the hollow spindle and a clamping flange.
- an eccentric is arranged over a Pin rests on the clamping spindle.
- the advantage of this known solution is that the tool without auxiliary tools, such as for example a wrench, can be changed.
- the user provides the Into the change position and turn the clamping flange off the clamping spindle and can thus remove the tool, for example, from the clamping device or also reposition.
- a disadvantage of the known solution is the actuating characteristic of the clamping lever.
- the operating force to be exerted by the user for the setting process is great, because high friction losses occur between the clamping lever and the clamping spindle.
- the tensioning lever can be in an intermediate position in which the tensioning device is neither tense nor relaxed.
- the present invention has for its object an electric tool with a To create quick release device that tensions without great operator effort by the user and can be relaxed. Furthermore, the quick release device should be clearly in one of the two states are located and be economically producible.
- the object is achieved in that the clamping lever in a radial Distance has a sliding element, which by pivoting the clamping lever about the axis of rotation with a deflection in relation to the longitudinal axis of the clamping spindle in contact with the end of the clamping spindle facing away from the tool can be brought, the clamping spindle has a contact surface with an extension in the pivoting direction, which at least corresponds to the sin (deflection) times the distance.
- the fact that the tensioning lever has a sliding element means that the user has to apply it Operating force is small because of the friction between the clamping spindle and the sliding element is very small. This is particularly useful for quick clamping devices with high clamping force Characteristic a considerable reduction in the operating force to be applied. There is also through the choice of the sliding element, it can be adapted to the required clamping force of the elastic element. If a high clamping force is required, there is, for example the possibility of using expensive sliding elements and thus very good ones To achieve sliding properties. In addition, in contrast to known solutions Quick release devices, the wear and tear when using a sliding element less, which means the service life even if the power tool is used excessively significantly extended. The dimensioning of the contact surface ensures one if possible compact design of the quick release mechanism in the power tool and promotes among other things, its manageability.
- the deflection is 30 ° to 120 ° to a good one To ensure the positioning characteristics of the quick release device.
- the choice of deflection also determines the stroke distance between the hollow spindle and the clamping spindle. The greater the deflection, the greater the stroke distance between the clamping position and the changing position.
- a long stroke also means less compact design Quick clamping device, since the extension of the contact surface with the deflection increased. In particular, for example in the case of hand-held circular saws, there has been a deflection of 80 ° proved to be optimal.
- the distance and the longitudinal axis included end angles between 5 ° and 30 °.
- the cocking lever either swivels in the clamping position or in the change position.
- the exact position of the clamping lever is determined by, for example, a stop surface. If necessary, the end angle ensures swiveling into the change position. ever the larger the end angle is chosen, the more stroke distance goes through the backward movement the clamping spindle is lost against the direction of the tool. On the other hand, the end angle snaps securely into the change position.
- the end angle is preferably 10 ° in order to ensure an optimal snapping in ensure compact design.
- the sliding element is advantageously by a bearing element parallel to the axis of rotation with a radius formed to be economical and at the same time for high clamping forces to ensure appropriate solution.
- Bearing elements are extremely resilient and are characterized by low friction and a long service life. Also is their production economically, since there is a great need for such elements.
- the radius corresponds to a preferred one Embodiment 0.2 to 0.6 times, in particular 0.4 times the distance.
- the quick release device has a clamping spindle mounted coaxially displaceably in the hollow spindle 2 4, which is axially braced by an elastic element 5.
- the elastic element 5 has one end in an end of the hollow spindle facing away from the tool 2 arranged step hole and is stored at the opposite end held by a flange 13 fastened to the clamping spindle 4.
- the clamping lever 6 is the Quick clamping device between a clamping position, as can be seen in particular from FIG. 1 and a change position, in particular shown in FIG. 2, can be set. In the The clamping position is the tool 3 between the hollow spindle 2 and a clamping flange 7 established.
- the tensioning lever 6 By pivoting the tensioning lever 6 from the tensioning position, shown in particular in FIG. 1 in the change position, which is shown in particular in Fig. 2, the Clamping spindle 4 by a sliding element 8, in particular by an annular bearing element, axially displaced towards the tool 3 against the force of the elastic element 5.
- the sliding element 8 has a radial distance a from an axis of rotation 9 of the clamping lever 6 on.
- the clamping flange 7 can be used without the aid of an auxiliary tool are rotated, for example, between the clamping flange 7 and the hollow spindle 2 stored tool 3 to be replaced.
- the clamping lever 6 is against a stop surface 12 of the housing 1 pressed.
- Fig. 2 shows the clamping lever 6 in a position in which it is in contact with the clamping spindle 4 stands, but does not yet exert any force on the elastic element 5.
- a position closes the longitudinal axis of the clamping spindle 4 with the radial distance a between the Axis of rotation 9 and the sliding element 8 an angle ⁇ , which is approximately 80 °.
- a contact area 11 has an extension K in the pivoting direction that is approximately sin ( ⁇ ) times corresponds to the distance a.
