Description
Technical Field
The invention relates to a brush assembly for treating the surface of a workpiece, comprising a rotatably drivable brush holder and an annular brush having a bristle crown with bristles projecting outwards.
Background
Brush assemblies of this type are typically used, for example, to remove corrosion, lacquer or similar coatings from the surface of the associated workpiece or to provide the surface of the associated workpiece with a desired roughness. For this purpose, a brush assembly is described in the prior art according to EP1834733B1 of the present applicant, of this type, which is equipped with a stop means. This makes it possible to achieve a roughness which hitherto could only be achieved by means of sandblasting. The roughness is overall the so-called mean roughness value Ra(as the arithmetic mean of the absolute values of the profile deviations within the reference length according to DIN 4764 and DIN ISO 1302). This has been inIn principle, this has proven to be reliable and has been used in practice many times. EP2618965B1 shows a similar prior art, in which the stop means simultaneously serves as a grinding tool for the bristles. For this purpose, the stop means can be adjusted, which are of radially and/or tangentially adjustable design, for example.
The brush assembly and the rotary brush tool equipped with the brush assembly can be used statically, for example in combination with a machine in a machine room. However, it is also possible to design the rotary brush tool mentioned as manually guided. In both cases, the following problems are generally present in practice: the brush assembly is guided along the workpiece or surface thereof to be treated. This can be done mechanically and/or manually, as described. This generally involves the following risks: grooves or at least a uniform structure are formed on the surface of the workpiece. These grooves or structures are disadvantageous for a uniform surface treatment and make the subsequent adhesion of coatings, pigments, etc. more difficult if not impossible. The invention proceeds from this.
Disclosure of Invention
The invention is based on the technical problem of further developing a brush assembly of this type for treating a workpiece surface in such a way that a homogeneously treated surface is provided.
In order to solve this problem, a brush assembly according to the invention within the scope of the invention is characterized in that the annular brush is configured to be adjustable (vertellt). The annular brush is usually designed to be adjustable in an oscillating manner.
The invention is based on the following recognition: the annular brush is held by a rotatably driven brush holder. The adjustment of the annular brush provided according to the invention is therefore carried out in such a way that the brush holder, which holds the annular brush and can be driven in rotation, performs an adjustment movement in addition to its rotational movement. In general, the annular brush is even and preferably of a pivotably adjustable design. The annular brush or the brush holder holding the annular brush thereby performs an oscillating movement which, in combination with a manually and/or machine-related feed movement, results overall in a homogeneous treatment of the surface of the workpiece to be treated and a homogeneous distribution of the roughness overall being obtained and observed.
According to an advantageous embodiment, the annular brush can be configured to be radially and/or axially adjustable. In general, work is carried out here by means of an axial-only adjustment of the annular brush and thus of the brush holder which receives and holds the annular brush. This means that, although additional radial adjustment of the annular brush is possible, it is in practice used only at best in mechanically guided brush assemblies in order to adjust the brush assembly and thus the annular brush, for example, in accordance with the respective workpiece to be treated or its surface. However, the invention relates firstly to a manually guided brush assembly and therefore especially to a manually guided rotary brush tool. The rotary brush tool is equipped with the mentioned brush assembly and additionally with a drive unit for the brush assembly.
In practice, such a manually guided rotary brush tool can be designed as a whole as a hand-held power tool or as a manually guided rotary brush tool. For this purpose, drive units are typically used which have an electric motor and optionally a transmission and are advantageously charged by means of one or more accumulators. In principle, however, the manually guided rotary brush tool can also be driven pneumatically. In any case, the feed movement of the rotating brush tool and thus of the brush assembly is advantageously effected generally manually. The possible radial adjustment movements or the adjustment of the brush assembly to the surface of the workpiece to be treated are also carried out manually. In contrast, the adjustment of the annular brush and in particular the axial adjustment thereof is effected mechanically, specifically by means of a drive unit which is already present and ensures the rotary drive of the brush holder and thus of the annular brush. In other words, the drive unit, as a component of the rotary brush tool equipped with the brush assembly, acts on the brush holder in a rotating manner on the one hand and in its axial direction, preferably in an oscillating manner, on the other hand according to the invention. For this purpose, the drive unit can be equipped with, for example, a motor or an electric motor for the rotary movement and a further motor or an electric motor for the oscillating axial movement. However, it is also possible to realize and implement both movements by means of only one electric motor.
As already explained, the annular brush is designed to be largely axially adjustable, wherein here an oscillating movement is generally involved. That is to say that the shaft of the respective retaining brush holder carrying the annular brush is oscillating and is moved back and forth in the axial direction by the drive unit. The oscillating axial movement can thereby follow a sinusoidal movement in time. Such a sinusoidal movement can be realized and implemented particularly advantageously by: the shaft of the brush holder is acted upon, for example, by a cam acting on the shaft, which reacts to the force of the spring and thus causes the sinusoidal movement of the shaft of the brush holder and thus of the shaft of the annular brush, which movement has been described above. This is because the annular brush and the brush holder are each generally rotationally symmetrical and are configured coaxially with respect to one another.
In order to be able to specifically carry out and realize the aforementioned axial adjustment of the annular brush of the brush holder, the brush holder is generally constructed at least in two parts. In practice, the brush holder is composed primarily of a stationary bearing part and, in contrast, a brush part which is axially movable. The brush part of the brush holder here ensures mainly the guidance and holding of the annular brush, while the bearing part primarily and exclusively assumes the bearing function for the brush part. The bearing part is therefore designed to be stationary, while the brush part is not only axially movable, but also rotates and thus also rotates the annular brush.
In particular, for this purpose, the stationary bearing part is equipped with a hollow bore for a pin of the axially movable brush part that can be inserted into the hollow bore. In this case, the pin of the axially movable brush element is movably mounted and can be connected to the base of the movable brush element. The stationary support part can thus perform the required rotational movement of the annular brush on the pin by means of the hollow bore.
In a further embodiment, it is provided in this respect that the stationary bearing part furthermore has a socket for inserting a plug-in bolt therein, which is acted upon rotationally and axially by the drive unit. In this case, the axial loading is additionally and in most cases also pendulum-type, so that the plug bolt is loaded rotationally and axially pendulum-type by means of the drive unit.
In order to realize and implement such a solution in particular, the socket is generally provided with a recess in which a lamella connected radially to the plug-in pin engages. The socket and the plug-in pin thereby ensure, on the one hand, a force-fitting coupling in the direction of rotation, in order to be able to drive the annular brush carried by the brush part in a desired manner in rotation. At the same time and on the other hand, the interaction between the groove and the lamellae embedded therein ensures that the plug-in pin can perform a desired axial movement relative to the socket and thus relative to the positionally fixed bearing part. This axial movement, together with the socket, additionally ensures that the plug bolt also rotates. For this purpose, at least two lamellae, which are connected radially to the plug pins, engage in corresponding recesses of the plug socket in a largely interlocking manner. Naturally, it is also possible here in principle to deal with this differently in terms of construction.
Of further particular interest for the present invention are the following cases: in addition, a stop means is provided which is sunk into the rotating bristle cap and ensures that the rotating bristles and/or the brush band carrying the bristles are elastically deformed as a component of the annular brush. The bristles and/or the brush strip can thereby be used to store kinetic energy, so that the bristles, after they have been released, not only rotate but at the same time also impact-treat the workpiece surface as a result of the stored kinetic energy released after passing the stop means. The basic functional principle of such a locking device is described by way of example in the patent EP1834733B1 of the applicant, which was already cited and referred to at the outset.
According to the invention, the stop means can be additionally or adjustably designed in this case, as is disclosed in principle in EP2618965B1, which is also described at the beginning of the description. In order to achieve an adjustment of the stop means in particular, the stop means can be adjusted, in general, radially relative to the axis of the rotating annular brush, with a change in the distance between them. In particular, this radial adjustment movement can be carried out in such a way that the stop means is adjusted by means of the eccentric and/or the linear adjustment element.
The possibility of additionally and optionally realizing the stop means and adjusting them according to the invention not only provides the option of treating the resulting surface homogeneously with respect to the roughness profile. The adjustment of the stop means in the radial direction relative to the axis of the ring brush also results in the kinetic energy with which the bristles impinge on the surface of the workpiece to be treated being changed.
In this case, the rule of thumb generally applies that the smaller the radial spacing dimension of the stop means from the axis of the annular brush in question, the higher the kinetic energy of the bristles. Since the radially inner arrangement of the stop means leads to an increased and violent deformation of the bristles and thus to an increased kinetic energy with which the bristles impinge on the surface of the workpiece.
These basic conditions have been studied by professor Robert j. Please refer to NACE International Corrosion CONFERENCE and exhibition No.10385 (NACE Corroschence & EXPO 2010, paper No.10385) "Surface Preparation of shift-configuration/(ABS-A) viA patterning process" in 2010 and NACE International Corrosion CONFERENCE and exhibition No. C2012-0001442 (CORROSION CONFERENCCE & EXPO 2012, paper No. C2012-0001442) "Evaluation of shift-configuration process for shift-configuration process". According to a preferred embodiment, the stop means is for this purpose largely adjustably designed or adjustable radially with respect to the shaft of the rotating annular brush. Similarly, the annular brush can be adjusted and/or an axial movement can be carried out in relation to the surface.
A rotary brush tool and in particular a manually guided rotary brush tool, which is equipped with the aforementioned brush assembly and a drive unit for the brush assembly, is also the subject of the present invention. In particular, the rotary brush tool can be designed to be self-contained if the drive unit is operated electrically and the energy supply device is equipped with an accumulator or at least one single accumulator arranged in the machine housing. Which can be seen as an important advantage.

figure 1 shows in a schematic side view a brush assembly according to the invention and a corresponding rotary brush tool,
figure 2 shows a stop means and an adjustment unit for the stop means in a first embodiment variant,
fig. 3 shows a further second variant of an adjusting unit for a stop means, and
fig. 4 shows schematically a drive unit according to the invention for rotationally and additionally axially oscillating adjusting a brush assembly.
Detailed Description
Fig. 1 shows a brush arrangement according to the invention for treating a surface of a workpiece 1, first and completely schematically. For this purpose, the brush assembly is connected to the machine housing 2 of the rotary brush tool. According to the present exemplary embodiment, in the interior of the machine housing 2 of the rotary brush tool there is on the one hand the illustrated drive unit 3 and on the other hand an energy storage device 4 for the electrically operated drive unit 3. The energy storage device 4 may be one or more batteries. The battery or batteries can be charged inductively via a charging socket in or on the machine housing 2 or recharged in an additional charging box after removal from the machine housing 2. In principle, however, the drive unit 3 can also be operated pneumatically, but this is not shown. The rotary brush tool shown with the machine housing 2 is advantageously a manually guided rotary brush tool, i.e. a correspondingly designed hand-held power tool.
In particular, the brush assembly has a rotatably driven brush holder 5, the individual webs of which can be seen in fig. 1. An annular brush 6, 8 comprising a bristle crown (borstekranz) 6 with outwardly projecting bristles 7 is held on the brush holder 5 and is rotationally driven by means of the drive unit 3. This corresponds to the counterclockwise rotational movement or direction of rotation D shown in fig. 1. The individual bristles 7 are carried by a brush band (B ü rstenband)8 and are anchored in the brush band 8 of the annular brush 6.
In the exemplary embodiment according to fig. 1, a stop means 9 can also be seen, which is sunk into the rotating bristle crown 6 or the rotating bristles 7. The stop means 9 is designed adjustably according to the present embodiment, in particular can be adjusted in the radial direction R indicated in fig. 1 by a double arrow. As already explained at the outset and explained in depth in the prior art according to EP1834733B1, the bristles 7 and optionally the brush belt 8 are elastically deformed during operation by means of the stop means 9 during a rotational movement thereof in the counterclockwise rotational direction D indicated by the arrow in fig. 1. The movement energy resulting from the corresponding elastic deformation is thereby stored in the bristles 7 or brush strip 8. After it has been released, the bristles 7 thus treat the surface of the workpiece 1 not only rotationally but also in a simultaneous impact manner. Since after passing the stop means 9 the previously stored movement can be released.
According to the invention, the annular brushes 6, 8 are designed to be adjustable, as shown in detail in fig. 4. In practice, the annular brushes 6, 8 are of pivotable, axially adjustable design. This is ensured by the drive unit 3.
For this purpose, the drive unit 3 is first equipped according to the present exemplary embodiment, corresponding to fig. 4, with a drive wheel 10 in order to drive the annular brushes 6, 8 or the brush holders 5 shown in fig. 4 in a rotating manner, corresponding to the previously mentioned direction of rotation D. For this purpose, the drive wheel 10 acts on a plug-in pin 12, which is described in more detail below, which engages in a hollow bore 13 of the socket B of the stationary bearing part 5a, which is part of the brush holder 5. In addition to the stationary bearing part 5a, an axially movable brush part 5b is also realized, to which the plug pins 12 belong. Furthermore, the drive unit 3 ensures that the mentioned plug bolt 12 is not only driven in a rotary manner for the purpose of carrying out the rotary movement D, but additionally also carries out the movement in the axial direction a already described above.
For this purpose, an eccentric cam 11' which can be rotated about an axis by the drive unit 3 is provided on the eccentric gear 11 which is acted upon by the drive unit 3 as a further component of the movable brush part 5 b. The eccentric cam 11' acts on the plug bolt 12 in the axial direction a by means of the bolt Z. The plug-in pin 12 and thus also the brush holder 5 execute a pivoting movement in the axial direction a, to be precise in addition to the rotational movement D. In order to be able to jointly realize the movement of the brush holder 5 in the axial direction a and additionally its rotation in the direction of rotation D, the drive wheel 10 and the eccentric 11, which are loaded by the drive unit 3, are each equipped with a corresponding toothing for driving by the drive unit 3.
As already explained, the brush holder 5 is designed in two parts in its entirety according to the present exemplary embodiment. In practice, the brush holder 5 has a stationary support part 5a and an axially movable brush part 5 b. The stationary bearing part 5a has a hollow bore 13 for the above-mentioned pin Z of the movable bearing part 5b or of the gear wheel 11. Furthermore, in the region of the socket B, a plug bolt 12 engages in the hollow bore 13, with which the brush holder 5 is finally driven.
The drive unit 3 now acts not only on the drive wheel 10 but also on the eccentric 11. The socket B is rotated via the transmission wheel 10. This then also applies to the stationary support part 5 a. The plug 12 engages in the hollow bore 13 of the socket B. The tabs 14 arranged radially on the plug pins 12 are inserted for this purpose into corresponding recesses 14' in the interior of the hollow bore 13. Thereby rotating the plug bolt 12 in the direction of rotation D.
An additional axial movement of the plug 12 in the axial direction a and following the double arrow in fig. 4 is then effected by means of the additional eccentric 11. For this purpose, the eccentric 11 is likewise rotated by means of the drive 3. The eccentric 11 has one or more radially protruding eccentric cams 11 'which interact with the stationary housing ramp 2'. In this way, the rotational movement of the eccentric 11 is converted into an axial movement by the interaction between the eccentric cam 11 'and the housing bevel 2'. The bolt Z inserted into the hollow bore 13 thus also performs an axial movement in the direction a.
The pin Z acts with its rounded head on the plug pin 12 in such a way that the plug pin 12, in addition to its rotational movement in the direction of rotation D, performs the desired axial movement in the axial direction a. This is possible because the lamellae 14 engage radially into one another in the associated recess 14', but at the same time allow a desired axial movement of the plug 12 in the axial direction a. The additional spring 15 ensures that the axial movement of the plug bolt 12 takes place against the force of the spring 15, which correspondingly returns the plug bolt 12.
Fig. 2 now shows a first exemplary embodiment of how the stop means 9 can be adjusted in particular in the radial direction R relative to the bristle crown 16 or the bristles 7. For this purpose, the stop means 9 are connected to an arm 16, into the bore of which an eccentric 17 is sunk. The eccentric 17 is itself driven in rotation by means of the drive unit 3. The rotation of the eccentric 17 in the bore of the arm 16 in combination with the additional guide 18 of the arm 16 ensures that the stop means 9 is moved in the radial direction R and optionally also in the circumferential direction U relative to the bristle crown 6 or the bristles 7, as indicated by the corresponding arrows in fig. 2.
Fig. 3 shows a further variant for adjusting the stop means 9 in the radial direction R relative to the annular brushes 6, 8 or the bristles 7. For this purpose, the stop means 9 are connected to the linear adjustment elements 19, 20. The linear adjusting elements 19, 20 consist of a fixed spindle nut 19 and a reciprocating spindle 20 which engages in the spindle nut 19. The rotational movement of the spindle 20 thus results in the arm 16 carrying the stop means 9 in this case moving in the linear direction shown in fig. 3, which according to the present exemplary embodiment corresponds to the radial direction R with reference to the ring brushes 6, 8 or the bristles 7.
