Definitions

  • the object of the invention is a method for deburring workpieces according to the preamble of patent claim 1.
  • the subject of the invention is also a device for carrying out the method according to the preamble of patent claim 4.
  • the invention seeks to remedy this.
  • the dwell time in the beam can be increased by slowing the rotational movement and / or the pivoting movement of the workpiece.
  • the device 1 shown in FIG. 1 for deburring workpieces 3 is arranged in a blasting cabinet 5, on the vertical wall 9 of which a driven shaft 11 with the axis A is mounted.
  • the shaft 11 is driven by a drive motor 10 accommodated in the blasting cubicle 5 (FIG. 2).
  • a support 13 is fixedly connected to the shaft 11 and rotatable about the axis A.
  • the support 13 contains the drive motor 15 for rotating a workpiece holder 17 mounted on an axis B and an actuating device 19 for opening and closing holding clips 21.
  • the holding clips 21 are pivotally attached to a turntable 23, on which supports 25 can also be provided for the point-like support of the workpiece 3.
  • retaining clips 21 with a length and design adapted to the workpiece 3 are arranged on the turntable 23.
  • the supports 25 can also be adapted to the shape of the workpiece 3 so that its center C comes to lie essentially at the intersection of the axes A and B.
  • the actuating device 19 for the retaining clips 21 can be a pneumatic, hydraulic or electrical ver have slidable wedge 31, which can pivot the retaining clips 21 against the force of a spring 35 to the outside via a bolt 33.
  • centrifugal wheel 29 is represented as a representative of such a blasting system.
  • the centrifugal wheel 29 can be pivoted about the axis D so that the beam 27 can be aligned with the center C of the clamped workpiece 3.
  • the generation of the jet 27 by means of a centrifugal wheel 29 or a jet nozzle of a known type and the device for aligning the jet 27 are preferred embodiments of this invention.
  • the blasted particles of the workpieces 3 and the blasting agent can be collected in the blasting cabin 5 and fed to a cleaning or regeneration system.
  • Fully automatic operation of the device can be achieved by a handling system which places the individual workpieces 3 on the supports 25 through an opening in the housing and grips and removes them again after deburring.
  • a handling device places the workpiece 3 on the supports 25; the retaining clips 21 are then pivoted inward by the spring 35 by pulling back the wedge 31 and hold the workpiece 3 securely.
  • the turntable 23 is rotated by the motor 15 about the axis B (arrow E).
  • the pivoting movement of the support 13 about the axis A begins.
  • the pivoting movement of the support is of course less than 360 °, because the pivoting range ends at the point where the lower arm 14 of the support 13 runs into the conical beam 27 of the particles coming from the centrifugal wheel 29 or crosses their trajectory.
  • the rotational speed of the turntable 23 and that of the support 13 can be set independently of one another and adapted to the workpiece 3. It is also possible to have the turntable 23 and / or the support 13 rotate at a non-constant speed in order to make certain off cuts on the effect 3 longer to expose the effect of the beam 27.
  • the supply of blasting agent to the centrifugal wheel 29 can be interrupted and an air jet directed onto the workpiece 3, which, when the support 13 is turned back, blows out any blasting agent residues accumulated in recesses and holes in the workpiece 3 .
  • the workpiece 3 is again in the starting position and can be gripped by the handling device after the holding clips 21 have been spread.
  • the handling device e.g. an industrial robot of known construction, takes the workpiece 3 from a means of transport, e.g. a conveyor belt or a monorail, and returns it to a means of transport after deburring.
  • the means of transport can consist of two belts or tracks brought up to the device; however, it can also be just a belt or a web that leads past the device, from or from which the workpiece 3 is removed and fed again after processing.
