Definitions

  • the present invention relates to an apparatus and a method for treating surfaces. Further, the invention relates to the use of a corresponding apparatus for treating surfaces, in particular surfaces of certain materials.
  • a hard material such as metal, glass, varnish, precious stones or the like is made smooth and optionally made to shine.
  • Very fine polishing agents are used, for example rouge cake, polishing slate, prepared chalk, tin ash, ceroxide and emery powder, which are applied for example to a cloth, felt, rubber, pitch or leather wheel and rubbed against the surface to be treated. This can take place manually or also with the use of machines, for example with polishing wheels.
  • Such electrically driven machines are equipped for example with a rotary polishing wheel made of felt or leather and are passed over the surface to be treated by means of a corresponding apparatus or by hand.
  • a disadvantage however is that the use of automatic means is only possible when the surfaces are substantially continuous or a flat surface structure is present. Problems occur when the surface comprises small projections or recesses, grooves or the like because the use of large polishing wheels is not possible. They cannot enter or only partially enter into such irregularities in the structure. For this reason, it is then necessary to rework these regions in an extensive manual work stage or to completely treat the surface manually in order to achieve the desired surface quality.
  • One possibility of countering this problem is to polish the surface electrolytically, although this procedure can only be used for electrically conducting materials. Preferably stainless steels or aluminum alloys are cleaned, deburred and made shiny by immersing the metal in a chemical bath and applying a direct current.
  • the surface structure can be changed, i.e. smoothed, only to a limited degree and additionally, the use of electrolytic baths is time and cost consuming.
  • an object of the present invention is to provide an apparatus and a method for treating surfaces, which at least partially overcomes the known disadvantages of the prior art.
  • the apparatus according to the invention comprises at least one first and second retaining device, the base surfaces of which are preferably substantially parallel to one another.
  • the first retaining device holds a first body, preferably a treatment tool and the second retaining device holds a second body, preferably the workpiece to be treated, or at least one body to be treated.
  • the first retaining device can be subjected to a predetermined force in a first direction, in particular a compressive force, where this takes place for example by means of a hydraulic cylinder or similar means.
  • the retaining device is movably mounted in a second movement direction or movement plane, which is substantially perpendicular to the direction in which force is applied.
  • the second receiving device is also movably mounted in a third movement direction or movement plane, which is substantially perpendicular to the direction in which force is applied to the first retaining device.
  • the invention is characterized in that the first and/or second retaining device is each driven by at least one generator and preferably by two generators.
  • the motion in the two and/or three movement directions or planes is thereby produced.
  • the generators of the two retaining devices are controlled, such that they oscillate or rotate with respect to one another in predetermined phases and the receiving devices are therefore set in relative motion to one another.
  • the movement of the retaining devices takes place in particular such that the resulting movement of the two receiving devices is counter directional to one another and preferably also variable.
  • the relative movement between the first and second retaining devices produces a superimposed oscillation or vibration, which depending on the basic oscillations (i.e. the movement of the first and second retaining devices in the first and second movement directions) can be varied in type and/or direction and/or intensity and used for treating the workpiece.
  • the treatment tool has a surface shape, which is substantially complementary to the surface shape of the body to be treated or corresponds to a matrix plate.
  • the treatment tool is configured such that when pressed to the surface of the workpiece, at least a partial region of the surface or the entire region of the surface is covered.
  • the matrix plate is formed, so that small undercuts of the body can be at least partially treated.
  • the matrix plates when the tool is joined with the workpiece, is introduced into the undercut region of the workpiece and subsequently altered in its extension, so that the undercut can be treated. This can for example take place in that the tool is spread in transverse direction.
  • the treatment tool is placed in direct contact with the surface of the workpiece for treating the surface.
  • an agent for example a polishing or grinding material, is placed between the tool and the workpiece.
  • Such grinding or abrading material preferably comprises a carrier, in which the material, for example corundum, silicate or the like with a predetermined grain size distribution is present.
  • Particularly preferred abrading materials comprise a carrier comprising paste-like, gel-like or other preferably high viscous or plastic materials.
  • Such agents are known in the prior art and are selected, in particular, depending on the workpiece to be treated and the surface quality to be achieved.
  • the surfaces of the tool and the workpiece remain slightly spaced from one another, where the distance results, among other things, from the amount and the selected grain size distribution of the agent.
  • the introduction of the agent takes place continuously or discontinuously.
  • the dosing of the agent can take place by means of at least one opening, preferably through the tool.
  • feed devices such as for example piston pump, screw extruders, monopumps or the like can be used, which are dimensioned to the pressure conditions and/or the type of agent to be dosed, in particular its viscosity.
  • the surface of the tool can comprise a correspondingly rough structure.
  • the surface of the tool is made up of a synthetic material, in which a predetermined grinding or abrading agent, such as corundum, silicate or the like is imbedded.
  • a predetermined grinding or abrading agent such as corundum, silicate or the like is imbedded.
  • the surface of the tool can directly polish or grind the workpiece surface.
  • additional agents for example as known in wet grinding. This can include water-based liquids, as well as those without water, for example oils or emulsions.
  • the first and/or second retaining device in a preferred embodiment is mechanically decoupled in the second or third movement direction from the direction in which compression force is generated, so that the movement in these directions is substantially independent from the transmission of force applied in the direction toward the work- piece.
  • This decoupling is provided through a tensile connection, which is arranged between the hydraulic cylinder for generating the compression force and the suspension of the retaining device.
  • the tensile connection which for example comprises a cable connection or any other pivotal connection subjected to tensile forces between the components, enables the transmission of the compression force.
  • the mounting of the pressing device is decoupled from the mounting of the retaining device for the oscillating movement to an extent that the cylinder of the pressing device remains substantially free of oscillation, even when the retaining device moves.
  • eccentric shafts are employed as generators for oscillation. These are preferably arranged with one end on the suspension of the retaining device or directly arranged on the retaining device via bearings. The respective other ends of the eccentric shafts are connected to the stationary housing or a counterweight, on which the drive for the eccentric shaft is arranged.
  • each retaining device has a plurality of generators with at least one eccentric shaft associated therewith, which are synchronized with one another.
  • a predetermined phase difference is provided, when desired, between the generators of the first and second retaining devices.
  • oscillations of the retaining devices are preferably circle-like (orbital movement).
  • the frequency as well as the rotation direction of the orbital movement of the two retaining devices can be independently adjusted from one another.
  • oscillation frequency and rotation direction of the two retaining devices a linear, elliptic or circular movement results between the tool and the workpiece, whose amplitude and frequency is adjustable in a wide range.
  • Such movements are also known as orbital or circular oscillations.
  • a combination of different types of oscillation is also within the scope of the present invention, where an overlapping effect is achieved for the polishing and/or grinding movement of the tool and the workpiece by superimposing the different movements between the first and second retaining devices.
  • the amplitude, frequency or phase difference is not always held constant, but can be varied during operation, where this can also be limited to certain angular segments of the rotary movement.
  • the oscillation of the generators is selected such that the oscillation direction, in particular for orbital or circular oscillations, is in opposing directions (counter directional) with respect to the first and second retaining devices.
  • Counter directional is understood here as an oscillation of the two retaining devices, whose movement direction at a certain point, preferably a contact point, is in different directions.
  • a linear oscillation results when the oscillations have the same phase, i.e. a phase difference of 0 or an integer multiple of ⁇ .
  • a circular oscillation results by using other phase differences of the oscillation generators through the resulting overlap of oscillations.
  • the direction of the polishing or grinding movement as well as the type of grinding movement and its amplitude and position can be determined by the selection of the phase angle difference between the generator oscillations of the first and second retaining devices.
  • the angular speed or frequency of the oscillations is not constant, but varies at least in predetermined angular segments. This means that the retaining device or retaining devices are driven with variable angular speed, so that grinding movements can also be generated, whose end points can also reach tight angle regions.
  • the present invention therefore allows the generation of various types of oscillations through the alteration of the phase relation and/or oscillation frequency, which makes different treatments of workpiece surfaces possible, depending on their surface composition.
  • the resulting superimposed oscillation has the particular advantage, that different movement patterns can be carried out depending on the workpiece to be treated, in particular to make sufficient account for the surface structure, for example with knobs or grooves.
  • the movement direction of the two oscillations can be selected such that the resulting superimposed oscillation runs along the groove, and the surface is substantially completely worked.
  • deeper lying edges and corners can also be handled with the polishing and/or grinding process.
  • the phases and/or the amplitudes and/or the frequencies of the two oscillations are varied during treatment of the surface and adapted to the surface composition of the workpiece during the course of the polishing and/or grinding process by means of a controller, so that an optimal treatment is achieved by specific adaptation of the resulting movement for every surface structure.
  • the application pressure can also be varied in the course of the treatment process.
  • the polishing and/or grinding path depending on the surface quality to be achieved, lies between 0 mm and 3 mm, preferably between 0 mm and 1.5 mm, particularly preferred between 0 mm and 0.75 mm and in particular is less than 0.75 mm.
  • the polishing and/or grinding path can be larger than 3 mm according to the present invention, where this especially occurs for relatively continuous surfaces or large workpieces to be treated.
  • the object of the present invention is also achieved by a method, by which an approximate form-fit connection is established between at least one treatment tool and one body to be treated.
