Definitions

  • the invention relates to a hand-held rotary brush tool, with a brush unit and a drive unit for the brush unit, the brush unit for processing the surface of a workpiece being equipped with a rotatably drivable brush holder and a ring brush with a bristle ring with outwardly projecting bristles.
  • Such brush units are typically used to remove corrosion, paint or comparable coatings from the surface of the workpiece in question or to provide it with a desired roughness depth.
  • the applicant describes a brush unit for this purpose, which is equipped with a stopping device. This allows roughness depths to be achieved that could previously only be achieved through sandblasting.
  • the specified roughness depths are overall so-called mean roughness values R a (as the arithmetic mean value of the absolute values of profile deviations within a reference distance in accordance with DIN 4764 and DIN ISO 1302). This has fundamentally proven itself and is often used in practice. The.
  • the stopping means can be adjusted, for example it is designed to be radially and/or tangentially adjustable.
  • Brush units and rotary brush tools equipped with them can be used stationary, for example in connection with a machine in a machine room. But it is also possible, the question in question Hand-held rotary brush tool.
  • in practice there is often the problem of guiding the brush unit along the workpiece to be processed or its surface. As described, this can be done mechanically and/or manually. As a result, there is often a risk that grooves or at least uniform structures will form on the surface of the workpiece. These are detrimental to uniform surface processing and may make it difficult for a coating, paint, etc. to subsequently adhere. This is where the invention comes into play.
  • the state of the art according to the DE 198 60 190 A1 deals with a device for cleaning a cylinder in connection with a printing press.
  • the cleaner is a brush roller.
  • the cleaner can be rotated using a rotary drive in coordination with the rotation of the cylinder.
  • the cleaner can be oscillated parallel to the lateral surface of the cylinder using an oscillation drive.
  • the invention is based on the technical problem of further developing a hand-held rotary tool in such a way that a homogeneously machined surface is provided.
  • the invention is a hand-held rotary tool according to claim 1.
  • the ring brush is designed to be regularly oscillating.
  • the invention is initially based on the knowledge that the ring brush is held with the help of the rotatably drivable brush holder.
  • the adjustment of the ring brush provided according to the invention therefore implies that the brush holder which holds the ring brush and can be driven in rotation carries out an adjusting movement in addition to its rotational movement.
  • the ring brush is designed to be oscillating and axially adjustable.
  • the ring brush or the brush holder holding the ring brush performs an oscillatory movement, which, in conjunction with a feed movement carried out manually and/or on the machine side, results in the surface of the machined workpiece being processed homogeneously and overall a homogeneous distribution of the roughness depth is present and observed .
  • the ring brush is designed to be axially adjustable. This involves merely axially adjusting the ring brush and consequently the brush holder that receives and holds the ring brush.
  • the drive unit as part of the rotary brush tool equipped with the brush unit works, on the one hand, in a rotational manner on the brush holder and, on the other hand, in the axial direction, namely in an oscillating manner. Both movements are realized and implemented with just one electric motor.
  • An additional radial adjustment of the ring brush is possible, but in practice it is only used with machine-guided brush units in order to adjust the brush unit and consequently the ring brush, for example, to the workpiece to be processed or its surface. According to the invention, however, it is primarily about manually operated brush units and consequently a particularly hand-operated rotary brush tool.
  • This Rotary brush tool is equipped with the brush unit in question and an additional drive unit for the brush unit.
  • such a hand-held rotary brush tool can be designed overall as a hand-held power tool or as a hand-held rotary brush tool.
  • a drive unit is typically used which has an electric motor and possibly a gearbox and is advantageously powered by one or more accumulators.
  • the hand-held rotary brush tool can also be driven pneumatically. Either way, the feed movement of the rotary brush tool and consequently of the brush unit is generally carried out by hand. Any radial adjustment movement or positioning of the brush unit on the surface of the workpiece to be processed is also carried out manually.
  • the adjustment of the ring brush and in particular its axial adjustment is carried out by motor, with the help of the already existing drive unit, which ensures the rotary drive of the brush holder and consequently the ring brush.
  • the drive unit as part of the rotary brush tool equipped with the brush unit works, on the one hand, rotationally on the brush holder and, on the other hand, in its axial direction, preferably in an oscillating manner.
  • the drive unit can be equipped with, for example, a motor or electric motor for the rotational movement and a further motor or electric motor for the oscillating axial movement. But it is also possible to realize and implement both movements with just one electric motor.
  • the ring brush is designed to be predominantly axially adjustable, with an oscillatory movement generally being used here. That is, the axis of the ring brush that carries or holds it Brush holder is oscillating and moved back and forth in the axial direction with the help of the drive unit.
  • the oscillating axial movement can follow a sinusoidal movement over time.
  • Such a sinusoidal movement can be realized and implemented particularly advantageously in that the axis of the brush holder is acted upon, for example, with a cam working on the axis, which works against the force of a spring and thereby the previously described sinusoidal movement of the axis of the brush holder and consequently of the axis the ring brush.
  • the ring brush and the brush holder are usually each designed to be rotationally symmetrical and coaxial with one another.
  • the brush holder is designed at least in two parts.
  • the brush holder is predominantly composed of the stationary bearing part and an axially movable brush part.
  • the brush part of the brush holder primarily ensures the guidance and holding of the ring brush, whereas the bearing part primarily and exclusively takes on a storage function for the brush part.

  • the stationary bearing part is equipped with a hollow bore for a pin of the axially movable brush part which engages therein.
  • the pin of the axially movable brush part is freely mounted and may be connected to a base of the movable brush part. This allows the stationary bearing part with the hollow bore on the pin to perform the required rotational movement for the ring brush.
  • the stationary bearing part also has the socket for the plug pin which engages therein and which is acted upon rotationally and axially by the drive unit.
  • the axial loading is additional and usually also oscillating, so that the plug-in pin is acted upon in a rotational and axially oscillating manner with the help of the drive unit.
  • the socket is generally equipped with grooves into which lamellas connected radially to the plug pin engage.
  • the socket and the plug-in pin ensure, on the one hand, a non-positive coupling in the direction of rotation in order to be able to drive the ring brush carried by the brush part in rotation as desired.
  • the interplay between the grooves and the slats engaging therein ensures that the plug-in pin can carry out the desired axial movement relative to the socket and consequently the stationary bearing part. Together with the socket, this also ensures that the plug pin also rotates.
  • at least two slats connected radially to the plug pin engage, for the most part, in a form-fitting manner in corresponding grooves in the socket. In principle, you can of course work differently in terms of construction.
  • a stop means immersed in the rotating bristle ring is also provided, which ensures that the rotating bristles and / or a brush band carrying the bristles are elastically deformed as part of the ring brush.
  • the bristles and/or the brush band are able to store kinetic energy, so that after their release the bristles not only rotate, but also impact the surface of the workpiece as a result of the stored energy released after passing through the stopping agent Process kinetic energy.
  • the stopping means can now be designed to be additionally adjustable, as is in principle also mentioned in the introduction to the description EP 2 618 965 B1 has become known.
  • the stop means can generally be adjusted radially in comparison to the axis of the rotating ring brush by changing its distance. This radial adjustment movement can be implemented in detail in such a way that the stopping means is adjusted using an eccentric and/or a linear actuator.
  • the rule of thumb generally applies that the smaller the radial distance of the stop means to the axis of the ring brush in question, the higher the kinetic energy of the bristles.
  • a radially inner arrangement of the stopping means leads to an increased and increased deformation of the bristles and consequently increased kinetic energy with which the bristles impact the surface of the workpiece.
  • the stopping means is largely designed to be adjustable radially in comparison to said axis of the rotating ring brush or can be adjusted radially in comparison to said axis.
  • the ring brush can also be placed on the surface and/or carry out an axial movement.
