Definitions

  • the invention relates to a method for machining a surface of a workpiece with the aid of a brush unit, with a brush holder which can be driven in rotation and a ring brush with a bristle ring with bristles projecting outwards, after which the rotating bristles, using an adjustable stopper dipping into the rotating bristle ring, and by Storage of kinetic energy are elastically deformed so that the bristles, after being released, not only work the surface of the workpiece in a rotating but also striking manner as a result of the stored kinetic energy released after passing through the stopping means.
  • the description also goes back to the applicant EP 2 618 965 B1 such a method in which the stopper also acts as an abrasive body for the bristles.
  • the stop means can be adjusted, for example, it is designed to be radially and / or tangentially adjustable. Eccentric adjustment is also possible.
  • the invention is based on the technical problem of further developing such a method for processing a surface of a workpiece with the aid of a brush unit in such a way that desired surface roughness depths can be set in a reproducible manner.
  • a generic method for processing the surface of a workpiece with the aid of a brush unit is characterized in accordance with the invention in that the stop means and / or the ring brush is adjusted depending on the roughness of the surface of the workpiece.
  • the first step according to the invention is that the stop means and / or the ring brush is adjusted as a function of the roughness of the surface of the workpiece.
  • the invention is based on the knowledge that a change in particular the radial position of the stop means in comparison to an axis of the brush holder holding the ring brush and which can be driven in rotation directly influences the roughness of the surface of the workpiece. Because through one Changing the radial position of the stop means in comparison to the axis of the ring brush ultimately changes the kinetic energy with which the bristles hit the surface of the workpiece to be machined.
  • the general rule of thumb is that the smaller the radial distance of the stopper from the axis of the ring brush in question, the higher the kinetic energy. This is because a radially inner arrangement of the stop means leads to an increased and increased deformation of the bristles and consequently increased kinetic energy with which the bristles strike the surface of the workpiece.
  • the stop means is largely adjustable radially in comparison to the said axis of the rotating ring brush or can be adjusted radially in comparison to the said axis.
  • the ring brush can also be placed on the surface and / or can perform an axial movement.
  • the roughness of the surface of the workpiece can in turn be detected tactilely and / or without contact.
  • the surface of the workpiece is actually recorded on the basis of the average roughness R A.
  • This is the arithmetic mean of the measured amount of deviation of the individual measuring point from a center line.
  • the information is made in accordance with DIN ISO 1302, such as this has been described in the introduction.
  • the so-called maximum roughness profile height R z can also be measured and evaluated. This is the sum of the height of a largest profile peak R p and the depth of the largest profile valley R v within a single measurement section.
  • R z is a measure of the scatter of the roughness coordinate values.
  • the procedure can be such that the roughness or roughness of the surface of the workpiece that has not yet been processed with the aid of the ring brush or the bristles is determined and the stop means and / or the ring brush is adjusted accordingly depending on this.
  • the procedure is such that the roughness of the machined surface is recorded.
  • the stop means can be moved accordingly, depending on the measured values determined for the roughness or roughness of the machined surface of the workpiece.
  • the roughness of the surface in question and processed is converted with the aid of a control unit into adjusting movements of the stop means and / or the ring brush depending on the desired roughness profile of the surface.
  • the values for the roughness or roughness of the surface is used as an input variable for controlling the control unit.
  • the stop means and / or the ring brush can now be adjusted accordingly. For example, if the average roughness R a is to be increased, the stop means will be moved radially further inwards with the aid of the control unit. Conversely , a radially outer position of the stop means is possible and conceivable for a reduced average roughness R a .
  • an actual value for the average roughness R alst is compared in the example with a target value of the average roughness R aSoll stored and specified in the control unit.
  • the stop means is then followed up in the sense of a closed control loop.
  • the roughness of the surface of the workpiece can be adapted to the actual requirements, for example a subsequent paint application, a plastic coating, a metal coating, etc.
  • the roughness of the surface can be measured tactilely with the aid of a stylus that mechanically scans the surface. As a rule, however, there is no contact at this point. Then the roughness of the surface can be scanned using, for example, sound waves and preferably using electromagnetic waves. At this point, scanning with electromagnetic waves, and here in particular with the aid of a laser, has proven to be particularly favorable and advantageous.
  • the procedure is usually that the surface of the workpiece to be machined or the already machined surface of the workpiece in question is scanned in the sense of a preferably two-dimensional triangulation method.
  • the laser beam is usually projected onto the surface to be measured as an extremely thin line of light at a defined angle.
  • the originally straight light line of the laser is distorted by the roughness or roughness of the processed surface in the example in proportion to the angle of incidence of the laser on the surface.
  • An image of this projected laser line can now be recorded using an optical recording device, for example a microscope in conjunction with a camera will.
  • the surface profile can now be calculated directly from the deflection of the light line and this method is particularly suitable for determining the average roughness R a .
  • the maximum roughness profile height R z can be determined in this way. Details of such a conceivable triangulation method are exemplified in the EP 0 585 893 A1 described. In addition, reference is made to a publication of the company "AMEPA” under “amepa.de” on the subject of "SRM - Online Roughness Measurement”.
  • the invention particularly preferably does not only resort to the possibility that the stop means can typically be adjusted in the radial direction relative to the ring brush.
  • the ring brush can advantageously be moved together with the stop means with respect to its distance and / or parallel to the surface of the workpiece, that is to say in the axial direction.
  • a parallel displacement or axial displacement of the ring brush in comparison to the surface of the workpiece also means that the roughness profile generated on the surface of the workpiece is designed to be particularly homogeneous and, in particular, has no preferred directions.
  • the subject of the invention is also a brush unit and a rotary brush tool, both of which are advantageous according to the method described for processing the surface work on the workpiece and are equipped with an appropriately designed brush unit.
  • a rotary brush tool is shown, which is equipped with a machine frame 1.
  • the machine frame 1 may in the exemplary embodiment and not as a limitation as a cylindrical frame section be formed, which is adapted to a workpiece 2 to be machined.
  • the workpiece 2 is, and is not restrictive, a pipeline or pipeline composed of individual pipes welded to one another.
  • the tubes are through one in the Fig. 1 weld 3 to be recognized joined together.
  • the surface of the workpiece 2 is machined in the area of the weld seam 3 with the aid of the rotary brush tool to be described in detail below. After this processing, a protective coating can be applied to the pipeline or the workpiece 2 in this area.
  • the rotary brush tool to be described in more detail below is of course not only suitable for machining surfaces on curved workpieces 2 such as that in FIG Fig. 1 shown pipeline or pipeline. Rather, the rotary brush tool can just as well be used to machine the surface of flat workpieces, but this is not shown in detail.
  • the rotary brush tool is held by the machine frame 1 according to the embodiment.
  • the machine frame 1 may be designed such that it engages around the workpiece 2 or the pipeline in the example of a claw.
  • the machine frame 1 rotates about an axis of the pipeline, so that the pipeline in question can be machined in the area of the weld seam 3 as a whole and over its entire circumference using the rotary brush tool.
  • the rotary brush tool now only has one in detail Fig. 1 partially recognizable drive unit 4, which has a brush assembly 5 as an essential component of the rotary brush tool in rotations transferred.
  • the brush unit 5 is equipped with a ring brush 6, 7, which is best in the Fig. 2 recognizes.
  • the ring brush 6, 7 is composed of a brush band 6 and bristles 7 connected to the brush band 6 and projecting outwards, which define a brush ring.
  • the brush belt 6 may be one made from a plastic woven belt based on, for example, polyamide.
  • the bristles 7 are equipped as steel bristles anchored in the brush band 6, which according to the embodiment in the Fig. 2 and can have non-restrictive bristle tips 7 ', each bevelled on the front. Of course, this only applies as an example.
  • the ring brush 6, 7 is received in a rotatably driven brush holder 8, which is best in the Fig. 1 recognizes.
  • the brush holder 8 can be designed as in the DE 43 26 793 C1 the applicant is described. In principle, other brush holders 8 are also conceivable at this point, such as those shown in detail in FIG WO 2017/220338 A1 be presented to the applicant.
  • the brush holder 8 for receiving the ring brush 6, 7 can be constructed in several parts, as described in the aforementioned publications. In principle, however, it is also conceivable for the ring brush 6, 7 to be firmly connected to the brush holder 8. As a rule, however, one will fall back on a multi-part brush holder 8 in accordance with the publications given above, already in order to be able to replace the ring brush 6, 7 if necessary and for closing.
  • An adjustable stop means 9 is then of particular importance for the rotary brush tool or the brush assembly 5.
  • the stop means 9 is connected to a cantilever 10, with the aid of which the stop means 9 with respect to its in the Fig. 2 distance A to the axis Z of the ring brush 6, 7 can be adjusted. That is through a corresponding one Arrow in the Fig. 2 indicated.
  • the adjustment of the stop means 9 with respect to its position in comparison to the bristles 7 is now carried out as a function of the roughness or roughness of the surface of the workpiece 2. That is, the stop means 9 is adjusted as a function of the roughness or roughness of the surface of the workpiece 9 .
  • the already machined surface of the workpiece 2, that is to say the region of the surface of the workpiece 2, which is used in FIG Fig. 2 followed by the direction of machining indicated by an arrow B follows the rotary brush tool or the brush assembly 5.
  • the component of the surface of the workpiece 2 leading in the machining direction B can also be used for the setting of the stop means 9. According to the exemplary embodiment and preferably, however, the procedure is followed in such a way that the area of the surface of the workpiece 2 following and already machined in the machining direction B is examined with regard to its roughness or roughness and the stop means 9 is adjusted as a function thereof.
  • a roughness measuring unit 11, 12, 13 is provided according to the exemplary embodiment.
  • the roughness measuring unit 11, 12, 13 lags the brush unit 5 or the rotary brush tool in its machining direction B in order to be able to detect the roughness or roughness of the surface of the workpiece 2 that has already been machined.
  • the roughness measuring unit 11, 12, 13 has a laser 11, a distance sensor 12 and a camera 13, for example a CCD camera 13.
  • the laser 11, the distance sensor 12 and also the CCD camera 13 are all connected to one control unit or control / regulating unit 14, which is used for the control and the detection of the roughness measured values R a , that is to say in the example and not restrictively determining the average roughness R a in accordance with the introductory explanations.
  • the laser 11 is directed at the surface of the workpiece 2 at a defined angle ⁇ and projects an extremely thin line of light on the surface in question.
  • This line of light is now examined with the aid of the high-resolution camera 13, which can be preceded by a microscope, which is not expressly shown, with regard to its distortions caused by the surface texture.
  • the surface profile in question can be calculated directly from the deflection of the light line compared to its straight course.
  • the image of this projected light line of the laser 11, which is distorted due to the surface texture, is recorded with the help of the camera 13 and this data is converted into the desired roughness values R a or the roughness values R a in question by the control unit 14 connected to the camera 13 are derived from this.
  • the additional distance sensor 12 is used primarily for control purposes and ensures that, in the event of any deviations of the surface of the workpiece 2 from one plane, bulges, etc., a perfect and sharp image of the straight line of light emitted by the laser 11 on the surface of the workpiece 2 remains is present and can be examined for its deviations through the surface texture. If necessary, the entire roughness measuring unit 11, 12, 13 can be changed in relation to its distance from the surface of the workpiece 2, as indicated by a double arrow in FIG Fig. 2 implies. The distance is changed in accordance with the measured values of the distance sensor 12.
  • stop means 9 can largely be adjusted radially in comparison to the axis Z of the ring brush 6, 7.
  • stop means drive 15 acts on the arm 10, which is rotatably mounted about the axis Z in the same axis as the ring brush 6, 7.
  • the stop means 9 can be varied with respect to its distance A in the radial direction in comparison to the axis Z of the ring brush 6, 7, as shown in FIG Fig. 2 implies.
  • the stop means drive 15 for the stop means 9 is finally realized.
  • the entire ring brush 6, 7 including the stop means 9 and the extension arm 10 can be placed against the surface of the workpiece 2 and lifted away therefrom, i.e. acted on in the vertical direction in comparison to the surface of the workpiece 2, as indicated by a corresponding double arrow 16 in the Fig. 2 implies.
  • the roughness depth of the surface of the workpiece 2 can also be influenced, as has already been explained above.
  • the stop means drive 15 and on the other hand the ring brush drive 16 are each connected to the control unit 14, such as corresponding electrical connecting lines in the Fig.
  • the ring brush drive 16 can also ensure that the ring brush 6, 7 is not only moved with respect to its distance in comparison to the surface of the workpiece 2, but alternatively or additionally also undergoes a change in position in comparison to the surface of the workpiece 2 in question. That is, the ring brush drive 16 may also be responsible for an axial movement of the ring brush 6, 7, as shown by the two double arrows in FIG Fig. 1 hint. Transferred to the Fig. 2 this means that the ring brush drive 16 also ensures a movement of the ring brush 6, 7 perpendicular to the drawing plane there or in the direction of the Z axis.
  • the procedure is now such that, depending on the roughness values R a of the surface of the workpiece 2 detected with the aid of the roughness measuring unit 11, 12, 13, the stop means 9 with the aid of the stop means drive 15 and / or the ring brush 6, 7 including stop means 9 Boom 10 can be adjusted in total by using the ring brush drive 16.
  • This can be done with the help of the control unit 14 in the sense of a control or advantageously in the form of a regulation.
  • the roughness values R alst in processing direction B are recorded behind the ring brush 6, 7 with the aid of the roughness measuring unit 11, 12, 13 and transferred to the control unit 14. A comparison of these actual values R alst with the target values R aSoll stored there takes place in the control unit 14.
  • the stop means 9 is now moved with the aid of the stop means drive 15 and / or the entire ring brush 6, 7 using the ring brush drive 16 in order to approximate in the course of a regulation between the target values R aSoll and the actual values R alst .
