Definitions
- the present invention relates to a hand tool, in particular a hammer drill or a chisel hammer, which automatically deactivates a pneumatic percussion mechanism as soon as a blank strike occurs, such as a hammer drill. from US 5,873,418 A known.
- the hand tool of the invention has a tool holder for holding a tool along a working axis.
- a motor-driven, pneumatic percussion has a driven by a motor exciter, coupled via a pneumatic chamber to the exciter racket and arranged on the working axis in the direction of impact behind the racket intermediate racket.
- a ventilation opening connects a cavity between the racket and the intermediate racket with the environment.
- a vent closing valve which is operated by the intermediate beater, is opened when the intermediate beater is pushed against the direction of impact to its working position. The ventilation opening ensures in normal working mode that the air pushed in front of the racket can flow off without appreciable resistance and when the racket is retrieved returns without significant heat resistance.
- the resistance should be increased specifically if the hand tool is not in working mode. As soon as the tool is not pressed against the ground by the user, the intermediate beater can leave the working position and consequently close the ventilation openings. The percussion now has to work against the air in front of the racket and loses its power.
- the valve has a closure body which is movable along the working axis and which is subjected to force in the direction of impact by a spring.
- the intermediate beater may abut against the impact body against the impact direction.
- the closure body includes a sleeve which is disposed within the cavity between racket and intermediate racket. In a first position, in which the sleeve is clamped between the intermediate racket and the spring in its working position, the sleeve releases the ventilation openings. The sleeve covers in a direction of impact from the first position advanced second position, the ventilation opening.
- An embodiment provides that the intermediate racket has a profiled lateral surface, with the intermediate racket in the working position does not cover the ventilation opening and covered in the direction of impact from the working position covers the ventilation opening.
- Fig. 1 a hammer drill Fig. 2 a striking mechanism
- Fig. 3 is a striking mechanism
- Fig. 4 is a striking mechanism
- Fig. 1 shows an example of a chiseling hand tool machine schematically a hammer drill 1.
- the hammer drill 1 has a tool holder 2, in which a shank end 3 of a tool, such as the drill 4, can be used.
- a primary drive of the hammer drill 1 is a motor 5, which drives a striking mechanism 6 and an output shaft 7.
- a user can perform the hammer drill 1 by means of a handle 9 and take the hammer drill 1 by means of a system switch 10 in operation.
- the hammer drill 1 rotates the drill 4 continuously about a working axis 11 and can beat the drill 4 in the direction of impact 12 along the working axis 11 in a substrate.
- Fig. 2 shows the exemplary pneumatic percussion 6 in a longitudinal section.
- a bat 14 is guided in a percussion tube 15 along the working axis 11.
- the racket 14 seals circumferentially with the impact pipe 15, preferably supports a sealing ring 16 in the periphery of the racket 14, the airtight seal.
- the exciter 17 is designed for example as a piston, which is arranged in the impact tube 15 in the direction of impact 12 in front of the racket 14.
- the exciter 17 closes with the impact tube 15 also circumferentially airtight, for example, supported by a sealing ring 18 in its lateral surface.
- the exciter 17 is motor-driven along the working axis 11 periodically moved back and forth.
- the exciter 17 is coupled for example by means of a connecting rod 20 to an eccentric 21.
- the eccentric 21 is driven by the motor 5.
- a wobble finger can be coupled to the exciter 17 as a periodic drive.
- the pneumatic chamber 19 is compressed and decompressed by the periodic movement of the exciter 17.
- the periodic changes in air pressure drive the bat 14.
- the racket 14 strikes an intermediate racket 22 (striker), which is arranged on the working axis 11 in the direction of impact 12 after the racket 14.
- the intermediate beater 22 is guided in a guide tube 23 along the working axis 11.
- the drill 4 or chisel is movably guided in the tool holder 2 on the working axis 11 and is, in operation, against the impact direction 12 at the intermediate rack 22 at.
- the user or the own weight of the hammer drill 1 press the tool 4 against the direction of impact 12 to the intermediate beater 22.
- the intermediate beater 22 is thereby brought into its working position in which the intermediate beater 22 abuts against the direction of impact 12 against a stop 24.
- the stopper 24 may be provided with a damper 25.
- the racket 14 strikes the intermediate racket 22 in its working position.
- the working position is chosen such that the time of flight of the bat 14 between two beats and the periodic movement of the exciter 17 are synchronous.
- the restoring force that holds the intermediate beater 22 in its working position is missing.
- the intermediate beater 22 can slip in the direction of impact 12 from the working position.
- a catcher 26 is provided, to which the intermediate beater 22 comes to rest in the direction of impact 12.
- the bat 14 now does not strike the intermediate beater 22 at the point of impact, as a result of which the flying time for the beater 14 increases with respect to the periodic movement of the pathogen 17.
- the pneumatic percussion 6 tends to turn off.
- the bat 14 can advance in the direction of impact 12 over its usual impact point and thereby releasing a ventilation opening 27, which allows air to flow from the environment into the pneumatic chamber 19.
- the impact tube 15 for exciter 17 and bat 14 and the guide tube 23 for the intermediate beater 22 are connected together.
- the exemplified impact tube 15 is inserted into the guide tube 23.
- the tubes 15, 23 may be screwed, soldered or welded.
- a further embodiment provides impact tube 15 and guide tube 23 monolithically connected, i. without permission to produce.
- the intermediate beater 22 has a sealing ring 28 in its circumference, which is intended in particular to prevent the ingress of dust.
- the racket 14 and the intermediate racket 22 thus close a cavity between them in the tubes 15, 23
- the cavity 29 has one or more ventilation openings 30, which are arranged in the impact tube 15 or the guide tube 23.
- the volume of the cavity 29 changes periodically with the movement of the racket 14. In order that during operation no counterforce to the movement of the racket 14 due to the pressure in the cavity 29 can build up, vent the ventilation openings the cavity 29 into the environment.
- the environment is, for example, the interior of the machine housing 13 or outside of the power tool 1.
- the ventilation openings 30 are arranged in the direction of impact 12 after the impact point of the racket 14. The pushed by the racket 14 air can escape during the entire movement of the racket 14 from the ventilation openings 30.
- the ventilation openings 30 are arranged in the direction of impact 12 in front of or the sealing rings 28 of the intermediate beater 22 when the intermediate beater 22 is in the working position.
- the ventilation openings 30 may also be formed as a partially axially extending channel.
- the inwardly facing mouth opening is arranged opening into the cavity 29 as mentioned above and optionally axially offset the other opening.
- the impact mechanism 6 has a valve 31 which closes the ventilation openings 30 when the intermediate beater 22 is displaced from the working position. This causes the bat 14 to apply a force against the pressure conditions both in its movement in the direction of impact 12 and against the direction of impact 12.
- the racket 14 slows down, whereby its time of flight in addition to the periodic movement of the exciter 17 is asynchronous.
- the displacement of the intermediate beater 22 is likely due to a recent strike by the bat 14.
- the bat 14 is thus still in the focal point when the valve 31 through the Intermediate racket 22 is closed.
- the pressure conditions in the adjacent to the racket 14 cavity 29 keep the racket 14 in a position near the impact point, for example in the direction of impact 12 against the impact point shifted.
- the racket 14 may abut a catcher 32 in the direction of impact 12.
- Fig. 2 shows in the two-part representation above the intermediate beater 22 in working position and below in a non-working position.
- the valve 31 includes a channel 33 and a closure body 34.
- the channel 33 leads in the radial direction up to the intermediate beater 22.
- the closure body 34 forms the lateral surface of the intermediate beater 22.
- the lateral surface has in the direction of impact 12 successively an annular first portion 35 with a larger Radius and an annular second portion 36 with a smaller radius.
- the intermediate beater 22 If the intermediate beater 22 is displaced from the working position, the first portion 36 of the lateral surface bears against the mouth opening of the channel 33.
- the radius of the first portion 35 corresponds to the distance of the mouth opening to the working axis 11.
- the channel 33 is closed.
- the valve 31 seals the cavity 29.
- the valve 31 may have a sealing ring 37 with an inner radius equal to the radius of the first portion 35, which is arranged in the direction of impact 12 in front of the mouth opening.
- Fig. 3 shows in a longitudinal section the striking mechanism 6 with another embodiment of the valve 38.
- the valve 38 is opened when the intermediate beater 22 is in the working position, and is closed when the intermediate beater 22 is displaced in the direction of impact 12 from the working position.
- the cavity 29 between the beater 14 and the intermediate beater 22 is vented or non-vented through the ventilation openings 30 depending on the switching position of the valve 38.
- the valve 38 has a channel 39 which opens into the cavity 29 with an orifice.
- a sleeve 40 forms the closure body of the valve 38.
- the sleeve 40 is arranged in the guide tube 23 and movable along the working axis 11.
- a spring 41 pushes the sleeve 40 in the direction of impact 12.
- the sleeve 40 covers the mouth of the channel 39 and closes in this way the valve 38.
- the valve 38 is automatically closing.
- the sleeve 40 has a collar 42 which projects radially inward.
- the intermediate beater 22 is opposite to the direction of impact 12 on the collar 42.

- the mouth opening is exposed, and the cavity 29 is vented through the valve 38.
- Fig. 4 shows a further modification.
- the striking mechanism 6 has, for example, a pot-shaped exciter 43.
- the exciter 43 has a cylindrical, open in the direction of impact 12 interior, in which the racket 14 is inserted.
- the pneumatic chamber 19 is the closed by the racket 14 interior.
- the point of impact of the racket 14 is defined by the intermediate rack 22 as in the previous embodiments.
- the cavity 29 between the beater 14 and the intermediate beater 22 is provided with the ventilation openings 30 to allow a pressure equalization of the cavity 29 with the environment during operation of the impact mechanism 6.
- a valve 44 closes the ventilation openings 30, except for the intermediate beaters 22 abuts against the stop 24, ie is in its working position.
- the valve 44 has a channel 45, which adjoins the ventilation opening 30.
- a shift rod 46 forms a closure body of the valve 44.
- the shift rod 46 is movable parallel to the working axis 11 and passes through the channel 45.
- the shift rod 46 has a thicker portion 47, which can completely close the channel 45, and one in the direction of impact 12th subsequent tapered portion 48, which can only partially close the channel 45.
- a spring 49 pushes the shift rod 46 in the direction of impact 12.
- the valve 44 is automatically closing, as the spring 49, the thicker portion 47 positioned in the channel 45.
- a pointing in the direction of impact 12 tip 50 of the shift rod 46 protrudes into the guide of the intermediate beater 22 in.
- the intermediate beater 22 in working position shifts the shift rod 46 against the force of the spring 49.
- the tapered portion 48 lies in the channel 45, so that air can flow around the shift rod 46.
