Definitions

  • the present invention relates to a device for mechanical or polishing of surfaces and / or edges according to the preamble of claim 1.
  • Such devices are for example as grinding or Deburring machines known. In doing so, one or several plate-shaped tools rotating in one Tool head arranged over the surfaces resp. Edges of led to machined workpieces. This can either manually using hand machines or mechanically correspondingly designed processing devices respectively. Such machining devices are actually only suitable for editing plans Workpieces, which are arranged on transport tracks under the appropriate tools for machining be passed through. With arbitrarily shaped three-dimensional workpieces are processed either manually with hand machines, which is too long Production times and high costs leads, or by means of robot arms with several degrees of freedom attached tools, which numerically controlled the Contours of the workpieces can be tracked. However, such devices are very expensive and are only suitable for very high processing quantities.
  • the object of the present invention was now a Find device of the type mentioned, which yourself for both editing plans as well of concave or convex surface areas of three-dimensional workpieces.
  • the effective area of the Tool steplessly stepless within certain limits adjust and thus the requirements depending on the adapt to the surface shape to be machined.
  • the smallest The effective area corresponds to the tool diameter if the Axes of rotation of the tool holder and the holding body swear.
  • the largest effective area is at maximum Eccentricity of the tool holder with respect to the axis of rotation of the holding body reached. This can advantageously with the small effective area the concave or convex Surface areas of the workpiece are processed and with the large effective area the planar areas of the Workpiece.
  • the cheapest effective area can be set. So that with a single device and one single tool reliably and quickly a Surface processing can be carried out, for example grinding and / or polishing. You can also so that the edges of such workpieces are machined such a device is suitable in particular also for deburring edges of such Workpieces.
  • the device according to the invention is suitable to accommodate practically any rotating one Tool for mechanical or polishing action on surfaces such as sanding plates, brushes, Deburring tools etc.
  • Another big advantage is that tool how holding bodies can be driven independently of one another. It can be used together with the adjustable Eccentricity through appropriate choice of speeds Affect processing effect or to adjust.
  • the very compact design of the The device according to the invention is particularly good for use with robotic arms.
  • the device also be integrated stationary in a machine, and the Workpieces to be machined are fed to it, for example by means of conveyor belts or likewise by means of holding means having several degrees of freedom such as robotic arms.
  • Figure 1 is a longitudinal section through a schematic Device according to the invention shown, with a plate-shaped brush 1 as a tool for the Surface processing of a workpiece.
  • the tool 1 is held in a tool holder 2, which is rotatable in a holding disc 3 is mounted.
  • the tool holder 2 is further via a cardan shaft 4 with a drive 5 connected.
  • the drive 5 can be, for example Be hydraulic motor, which from a hydraulic pump (not shown) is fed. Of course you can the drive 5 can be an electric motor, for example.
  • the drive 5 is on the support body 6 of the device appropriate.
  • This support body 6 can with the Machine housing of a processing machine can be connected or preferably also with the end of a robot arm.
  • the holding disc 3 is now eccentric in the end face one designed as a cylindrical hollow body Holding body 7 also rotatably arranged.
  • the Retaining disk 3 can have an inside of the holding body 7 attached drive, which for example via a Pinion on an internal ring gear 8 in the holding disc 3 acts, be twisted.
  • This drive is for example an electric motor.
  • Funding for the confirmation of the position, i.e. the angle of rotation of the Holding disc 3 may be present with respect to the holding body 7.
  • a Control device control this drive to a set certain, desired eccentricity.
  • a stepless setting can also be set in Intervals set discrete eccentricity positions be displayed via simple contacts can.
  • the holding body 7 is in turn rotatable on the Carrying body 6 arranged in a bearing.
  • the Distance between the axis of rotation 9 of the holding body 7 and the The axis of rotation 1 'of the tool 1 determine the dimension of the Eccentricity of the tool 1.
  • the holding disc 3 In the lower end position the holding disc 3 become the axis of rotation 1 'of the tool 1 and the axis of rotation 9 of the holding body 7 preferably for Brought cover, i.e. the two axes of rotation are aligned.
  • the device according to the invention thus acts like one conventional device with a fixed drive shaft.
  • the holding body 7 is driven by its own drive 10, for example also a hydraulic motor, in rotation transferred.
  • the drive 10 is on a pinion 11 an internal toothing 12 of the holding body 7.
  • the drive 10 of the holding body 7 is independent of the drive 5 of the Tool 1 controllable.
  • it can depending on the eccentricity of the holding disc 3 different machining effects of the tool 1 by corresponding variation in the number of revolutions of the two Drives 5 and 10 can be reached.
  • FIG 2 is the front view of the end face of the holding body 7 with dotted lines Tool 1 shown.
  • Tool 1 Here is the training of the Holding disc 3 and the eccentric arrangement in the Holding body 7 can be seen.
  • the holding disc 3 has reached the maximum eccentricity.
  • the axis of rotation becomes 1 'of the tool 1 respectively.
  • the tool holder 2 on the Axis of rotation 9 of the holding body 7 shifted, whereby the Eccentricity 0 is reached.
  • Figure 3 shows the hatched Area of effect of tool 1 at the minimum Eccentricity, i.e. in the illustrated embodiment this corresponds to the eccentricity 0. Accordingly the effective range corresponds to the diameter of the Tool 1.
  • Figure 2 is hatched Area of effect shown with maximum eccentricity, which by the eccentric arrangement of the axis of rotation 1 'of Tool 1 is reached.
  • the intensity of the effect of the Tool 1 depends on the rotational speeds of the two axes of rotation 1 'of the tool 1 and 9 of Holding body 7 from.
  • the device according to the invention becomes a workpiece operated with minimal eccentricity, as in Figure 5 is shown schematically. With the same attitude advantageously also become convex surface areas processed.
  • the eccentricity can also be selected smaller, for example if Machining width is smaller than the diameter of the maximum range of action of the device.
  • the device according to the invention is suitable advantageously for the machining of surfaces different qualities, such as Metal, wood or plastic.
