Definitions
- the invention relates to a hand tool according to the preamble of claim 1.
- the invention is based on a hand-held power tool having a housing, a vibration body provided for oscillation relative to the housing, and a connecting means fastening the vibration body to the housing.
- the connecting means comprise a receiving part which can be mounted in the housing and a vibration element which is separate from the receiving part and provided for deformation.
- This division of the connecting means in receiving part and separate vibrating element has the advantage that the receiving part and the vibrating element can be made in a simple manner of different materials and the
- Material of the receiving part and that of the vibrating element to the task of the receiving part or the vibrating element particularly can be effectively adjusted.
- the forming and fixing receiving part made of a solid plastic and the vibrating element of a more elastic plastic or a durable elastomer can be produced.
- the housing has two housing elements, which are fastened to one another by a fastening means, wherein one of the housing elements can be removed from the oscillating body by releasing the fastening means. It can - for example, for the purpose of repair - an easy access to the arranged in the housing components are created without the removable housing element must be additionally separated from the connecting means or the associated oscillating body. As a result, a repair can be facilitated, and it can be reduced assembly errors after repair of the power tool.
- both housing elements are arranged in the immediate vicinity of the connecting means.
- Housing elements can be stably connected to the vibrating body by the connecting means. With equal advantage, both housing elements are each independently secured by the connecting means on the oscillating body.

- the receiving part has a receiving means which is provided for receiving the vibrating element during assembly of the vibrating element. In this way, a quick mounting of the vibrating element can be achieved in the receiving part.
- the receiving means may be an opening into which the oscillating element may be inserted or screwed.
- the receiving means and the vibrating element in the mounted state form a frictional connection.
- This offers the advantage that a stable attachment of the connecting means to the receiving part can be done without tools.
- this assembly is facilitated because the vibrating element after the connection of the vibrating element with the receiving part frictionally, so by itself, is held on or in the receiving part and not unwanted again falls out.
- a positive connection between the receiving means and the vibrating element is advantageous, which prevents rotation of the vibrating element in the receiving means. It can be avoided twisting of the vibrating element and thereby effected wear of the vibrating element.
- the oscillating element has at least one polygonal oscillating leg.
- the receiving part is inserted into a pocket-shaped cavity of the housing. This offers the advantage that the receiving part can be easily, quickly, without tools and error-free mounted in the housing and removed from it.
- a housing element can be removed from the receiving part mounted in the other housing element and remaining there when the oscillating element is completely assembled. As a result, a simple disassembly and repair can be achieved.
- a particularly stable attachment of the receiving part to the housing can be achieved in that the receiving part and the housing in the assembled state form a tongue and groove connection.
- a further embodiment provides that the housing has two housing elements, wherein the receiving part in both housing elements can be inserted, in particular transversely to an eccentric axis.
- the receiving part can be particularly easily mounted in both housing elements.
- the receiving part is first inserted into a mounting cup where other components, e.g. Switch, motor and armature, already arranged.
- a cover shell is mounted, wherein the receiving part is advantageously inserted into a receptacle of the cover shell.
- each housing element has a pocket-shaped cavity into which the receiving part can be inserted separately in a mounting direction.
- a stable tool-free attachment of the receiving part to the housing can be achieved in that the receiving part and the housing in the assembled state form a frictional connection.
- the oscillating elements can be introduced into the receiving part when the receiving part is arranged in the housing, in particular inserted.
- defective vibrating elements can be easily removed and replaced without the housing elements must be dismantled.
- FIG. 1 shows a mounting shell, a swing plate and mounted in the mounting shell inner components of an eccentric grinder with the mounting cup with the swing plate connecting connecting units
- Fig. 4 is a detail view of Figure 1 with the inserted into the mounting cup and in the vibration plate connection unit and
- FIG. 1 shows a schematic representation of an eccentric grinder without a removed cover shell, which is shown separately in Figure 2.
- the eccentric grinder comprises a housing element designed as a mounting shell 10 of a housing 12, an electric motor 14 and one of the
- the connection of the oscillating body 18 with the housing member 10 is effected by a connecting means 22, which comprises two separate connection units 24 , Each connecting unit 24 has a receiving part 26 and two oscillating elements 28 designed as oscillating legs, each of which is designed with a hexagonal cross-section.
- the oscillating body 18 comprises
- the housing element 10 is configured with pocket-shaped cavities 32 into which the receiving parts 26 of the
- connection units 24 are inserted. At the edge of each pocket-shaped cavity 32 sit two each a tongue and groove connection with the receiving part 26 producing projections 34.
- the housing member 10 has a plurality of fastener receiving means 36 which are each provided for receiving fasteners 38, which are shown in Figure 2.
- FIG. 2 shows a housing element 40 embodied as a cover shell. It has a plurality of fastening means receptacles 42, which are designed as elevations or, viewed from the outside, as depressions into which the fastening means 38 are introduced from the outside.
- the fastener receptacles 42 are arranged in the cover shell such that when the housing 12 is closed, each fastener receptacle 42 sits opposite one of the fastener receptacles 36 of the mounting shell or the housing element 10 and the fasteners 38, for example screws, can be inserted into the fastener receptacles 36.
- the housing member 40 also includes pocket-shaped cavities 44, which are arranged in the mounted state of the eccentric grinder against the pocket-shaped cavities 32 of the housing member 10 and in which the receiving parts 26 are inserted in the assembled state of the eccentric grinder. At the edge of each pocket-shaped cavity 44 two respective tongue-and-groove connection with the receiving part 26 producing projections 46 are configured.
- the vibrating body 18 In operation of the eccentric grinder, the vibrating body 18 is driven by an eccentric, not shown, which is fixed to the output shaft 16. The eccentric performs this circular movements that are transmitted to the vibrating body 18.
- the oscillating elements 28 prevent this a rotation of the vibrating body 18 relative to the housing 12 and also hold the vibrating body 18 stable against tilting relative to the housing 12 fixed to the housing 12.
- the vibrating elements 28 are made of a material intended for elastic deformation, for example made of rubber, and allow the Oscillating 18 performs the force imposed by the eccentric oscillating movement relative to the housing 12.
- the inner components including the electric motor 14 and the first
- connection means 22 can still be easily mounted in the housing element 10 even when the output shaft 16 is already mounted.
- the housing member 40 is placed on the housing member 10, whereby the receiving parts 26 are inserted into the pocket-shaped cavities 44 of the housing member 40.
- the housing member 40 is then replaced by means of the fastener 38, e.g. by screws, attached to the housing member 10, whereby the housing 12 of the eccentric grinder is closed.
- the oscillating elements 28 are each inserted into one of the receiving parts 26. Subsequently, the vibrating elements 28 are pushed by a slight pressing on the vibrating body 18 relative to the housing 12 in the vibrating element receptacles 30 of the vibrating body 18. Finally, the oscillating body 18 is fastened to the eccentric by means of a screw.
- the receiving parts 26 are both with two housing elements 10, 40 and with all the vibrating elements 28 positively connected, whereby these parts can be mounted easily and reliably without errors.
- the housing member 40 formed as a cover shell must be removed to gain access to the internal components.
- the eccentric grinder must not be disassembled analogously to the assembly in the reverse order, but it is sufficient to solve the fastener 38 and lift the cover shell of the trained as a mounting shell housing element 10.
- the cover shell can be deducted from the receiving parts 26, which remain together with the oscillating elements 28, the oscillating body 18 and the attachment to the eccentric in the mounting cup.
- Vibrating body 18 is released on the eccentric, and the vibrating elements 28 are separated by a slight pulling on the vibrating body 18 of the vibrating element receptacles 30 of the vibrating body 18.
- the oscillating elements 28 can then be removed from the receiving parts 26, without the housing element 40 has to be dismantled.
- FIG. 3 shows the connecting unit 24 with the two oscillating elements 28, which are respectively inserted into one of the oscillating element receptacles 30 of the vibrating body 18 in the mounted state of the eccentric grinder.
- the rotation of the vibrating elements 28 during operation of the eccentric grinder in both the receiving part 26 and in the vibrating element receptacle 30 may cause an undesirable abrasion of, for example, the vibrating elements 28.
- the receiving part 26 has a groove 48 which is arranged parallel to the swing plate 20.
- connection unit 24 is shown mounted in the housing member 10.
- the receiving part 26 is inserted into the pocket-shaped cavity 32 of the housing element 10.
