Definitions
- the invention is based on a tool adapter according to the preamble of claim 1.
- Rubber plates for attaching sanding papers to, for example, a drilling machine are known, which are clamped non-positively into the chuck of the drilling machine.
- the sanding paper is held on the rubber plate by a larger drive disc, which in turn is connected to the rubber plate by a screw.
- the invention is based on a tool adapter for fastening a disk-shaped tool on a driving device of a handheld power tool, which has a tool holding means for connection to the tool. It is proposed that the tool adapter have a fastening means for a form-fitting fastening to the driving device.
- Tools can be connected to the driving device of the hand-held power tool, the design of which does not have to be adapted to the driving device.
- a tool with a simple hub that does not have any special fastening means can be arranged on a driving device with specially designed fastening elements.
- the form-fit connection ensures that the tool adapter is held in a particularly stable manner on the driving device.
- the tool adapter is prepared in such a way that it can be attached to the mounting device of a complete hand tool.
- the driving device of the hand power tool is thus a tool driving device.
- the tool adapter is therefore not a part of the hand-held power tool, but a separate component that is independent of the hand-held power tool and can be attached to the driving device like a tool.
- the tool holding means is advantageously provided for the non-positive connection with the tool, whereby a simple fastening of the tool can be achieved.
- the tool can be held in addition to the frictional connection by an additional positive connection.
- the frictional connection is expediently carried out in the tangential direction and the additional positive connection in the axial direction.
- the tool can be held on the tool adapter in a particularly simple but nevertheless firm and secure manner.
- the tool holder can be a Include threaded element through which the positive and positive connection is established.
- the tool holding means expediently comprises a centering element. An imbalance of the tool during a machining process can be counteracted.
- the fastening means be provided for the positive connection in the tangential direction with the driving device. A large moment of force can be transferred to a rotating tool without the tool adapter having to be clamped.
- the fastening means is advantageously formed by a cup-shaped element.
- a relatively large area can be used on the inner wall or outer wall of the pot-shaped element to accommodate a large driving force. Wear of the fastener and thereby of the tool adapter can be counteracted.
- the pot-shaped element can be designed with a lid, a partially implemented lid or entirely without a lid, for example in the form of a hollow cylindrical element.
- the tool adapter can be securely connected to the driving device without clamping if the fastening means is provided for a positive connection to the driving device in the axial direction.
- a form fit in the tangential direction can be provided with the driving device.
- a particularly secure form fit in the axial direction can be achieved if the fastening means comprises a holding element which can be gripped behind in the axial direction.
- the holding element thus has a side facing away from the driving device, which can be supported in the axial direction by, for example, a hook-shaped holding means of the driving device.
- the holding element is designed in particular in the form of a segment of a circle, so that it can be rotated under a holding means of the driving device by a rotary movement of at least part of the tool adapter. This rotation enables the tool adapter to be locked in the axial direction on the driving device.
- a positive connection of the tool adapter to the driving device, in particular in the axial direction, can be achieved in a particularly simple manner if the fastening means comprises an opening through a plate element extending in the radial direction.
- a holding means of the entraining device guided through this opening can secure the plate element and thus the tool adapter in a positive manner in the axial direction and expediently additionally in the tangential direction.
- the plate element is at least partially plate-shaped and is, for example, a sheet metal.
- a centering element for centered mounting on the driving device can be used to counteract imbalance of the tool adapter during a machining process in a simple manner.
- the centering element is, for example, a centering breakthrough, in particular through the plate element, which enables centering even without a corresponding opening can be achieved in the driving device.
- the driving device can be made compact.
- the centering element advantageously has at least one recess in the radial direction.
- the tool adapter can be adapted to a coding of the driving device, and a clear association between the tool adapter and a coded driving device can be achieved.
- the suitability of the tool adapter for a quick-action clamping system can be achieved by a button element arranged on one tool side.
- the button element can be operated from the side from which the tool is arranged on the tool adapter and is therefore easily accessible.
- a release device in the driver device can be actuated and the tool adapter can be released from the driver device in a particularly simple manner.
- the key element can have any suitable shape and is a functional element which can be displaced by pressure relative to the surroundings.
- the key element is expediently arranged at least partially in the tool holding means. In this way, a central position of the key element in the tool adapter can be achieved and thus an imbalance of the tool adapter can be counteracted.
- the key element can advantageously be operated from a tool side and comprises a functional element on a driving side opposite the tool side.
- the entraining side faces the entraining device during an operation, as a result of which the entraining-side functional element can directly or indirectly actuate a corresponding functional element of the entraining device, for example a button element.
- the key element has an operating element which, when not in use, is at least largely recessed into a recess. Additional security can be achieved by means of a spring element which is biased against a direction of actuation in order to preload the button element
- a simple manufacture of the tool adapter can be achieved by a first main element comprising the tool holding means and a second main element separable from the first main element and comprising the fastening means.
- the tool holding means and the fastening means can thus be produced separately and can be directly or indirectly connected to one another by suitable connecting means for the fixed connection of the two main elements, for example screws.

- FIG. 2 shows a driving device for the angle grinder
- FIG. 3 shows an exploded view of a tool adapter
- FIG. 4 shows a main element of the tool adapter with the cutting disc attached to it.
- Figure 1 shows an angle grinder 2 from above with an electric motor mounted in a housing 4, not shown.
- the angle grinder 2 can be guided using two handles 6, 8.
- a tool 12 designed as a cutting disc can be driven in a tangential direction 14 via the electric motor, a gear (not shown) in a gear housing 10 and a drive shaft (likewise not visible).
- the driving device 16 comprises a driving flange 18, a centering collar 20, three identically see fastening elements designed as locking bolts 22 and three likewise identical fastening elements 24 designed as tensioning hooks.
- An actuating button 26 is arranged in the center of the centering collar 20. Radially outward, three coding lugs 28 protrude from the centering collar 20.
- FIG. 3 shows a tool adapter 30 with a first main element 32, shown at the top in FIG. 3, and a second main element 34, which is shown below the first main element 32.
- a tool holding means 36 which comprises a threaded element 38 and a centering element 40.
- a key element 42 is arranged partially within the tool holding means 36 and comprises an actuating element 44 on a tool side and a functional element 46 on a driving side. The actuating element 44 is screwed onto a central core of the key element 42 for simple assembly.
- the second main element 34 comprises a plate element 50, which comprises three first fastening means 52 designed as a pot-shaped depression and three fastening means 54, each with an opening 56.
- a centering element 58 designed as an opening, with three radial recesses 60, of which only one is visible, is arranged centrally in the plate element 50.
- the tool adapter 30 comprises four screws 62 which are each passed through a hole 64 in the connecting flange 48 and screwed into a threaded bore 66 of the first main element 32. It is also possible to bond the two main elements 32, 34 to one another after their manufacture connect, for example by welding. A one-piece production of the tool adapter 30 is also conceivable.
- the driving device 16 shown in FIG. 2 is designed as a quick-action clamping system, to which tools with a tool hub configured in accordance with the plate element 50 can be attached simply, quickly and securely.
- disk-shaped tools such as grinding disks, grinding disks, cutting disks, saw blades or the like of the simple type usually only have a circular centering opening and cannot be connected to the driving device 16.
- Tool adapter 30 is provided for this purpose. The tool adapter 30 can be connected to the driving device 16 and can in turn hold simple disk-shaped tools.
- the centering element 58 is pushed onto the centering collar 20.
- the plate element 50 rests on the three coding elevations 28 and can now be rotated in the tangential direction 14 until the three recesses 60 cover the three coding elevations 28.
- the plate element 50 - and with it the entire tool adapter 30 - falls somewhat lower until it comes to rest on the three locking bolts 22.
- These three locking bolts 22 are spring-loaded and can be pressed down by an operator of the angle grinder 2 by pressing the tool adapter 30 until the tool adapter 30 is on the center takes flange 18 rests. As a result, the hook-shaped fastening elements 24 pass through the openings 56.
- the plate element 50 can now be rotated clockwise, as a result of which a radially innermost area of the plate element 50 is passed under the coding elevations 28.

- a prestressed spring not shown
- the holding element 68 is pushed under a nose 72 which is aligned parallel to the driving flange 18 and which presses the plate element 50 onto the driving flange 18 with the aid of the prestressed spring (not shown).
- the locking bolts 22 come into congruence with the pot-like fastening means 52 of the tool adapter 30 and snap into these fastening means 52 as a result of a snap-up.
- the plate element 50 - and with it the entire tool adapter 30 - is now fixed in the tangential direction 14 by the locking bolts 22 in the pot-like fastening means 52 and in axial Alraum held by the retaining elements 68 engaging behind and spring-loaded fasteners 24.
- the tool 12 can now be clamped onto the first main element 32 arranged on the tool side, the sequence of the connection of the tool with the first main element 32, the first main element 32 with the second main element 34 and the second main element 34 with the driving device 16 being arbitrary.
- the tool 12 is guided over the tool holding means 36 with a centering breakthrough, not shown, and placed around the centering element 40.
- a pressure element 74 shown in FIG. 4 and designed as a clamping nut is then screwed with its internal thread onto the threaded element 38 until the tool 12 is firmly clamped between a base plate 76 of the main element 32 and the pressure element 74.
- a clamping nut another clamping element which cooperates with the tool holding means in a suitable manner can equally well be used, the threaded element 38 possibly being replaced by a suitable other element.
- the pressure element 74 with its outer shape is designed like a hexagon tool nut and can be held with a wrench.
- a possibly existing spindle lock of the angle grinder 2 can be actuated, which prevents the driving device 16 from rotating.
- the two main elements 32, 34 are included each have two flattened sides 78, which can also be gripped with a large wrench. Now the two wrenches can be turned against each other around the sides 78 and around the pressure element 74 until the pressure element 74 firmly fixes the tool 12 on the
- Base plate 76 prints.
- the tool 12 is fastened on the tool adapter 30.
- the operator of the rotary grinder 2 can print the actuating element 44 in the axial direction to the gear housing 10 of the angular grinder 2, as a result of which the functional element 46 on the driving side prints on the actuating button 26 of the driving device 16.
- the locking bolts 22 are pulled down and out of the pot-like fastening means 52.
- the tool adapter 30 can be rotated counterclockwise and can be detached from the driving device 16.
- the actuation element 44 is completely sunk inside the pressure element 74.
- the key element 42 is biased axially away from the transmission housing by a spring element 80 designed as a spiral spring, so that the actuation button 26 is not inadvertently actuated by the dead weight of the key element 42 during operation, even when the tool adapter 30 is hard knocked.
