Definitions

  • the invention relates to a device for deburring a workpiece according to the preamble of claim 1.
  • Such deburring devices are used for surface treatment and deburring of workpieces in which burrs or sharp edges have been created by a preceding mechanical working process, such as, for example, cutting, milling or drilling.
  • a device is known from the utility model DE 78 07 217 U1 known.
  • This document discloses an adjusting device for a rotary brush on deburring, brushing machines or the like. On a receiving ring brush fingers are held, which are directed through concentrically arranged holes of a holding plate against a processing plant. The distance between the holding plate and the receiving ring is held by a biased inserted compression spring. By moving an adjusting wheel, the position of the receiving ring is determined with its brush fingers relative to the holding plate.
  • a deburring device with at least one brushing tool which has a rotating support plate in which at least one brush is held and arranged axially or at an angle to the axis of rotation of the support plate. Furthermore, the brushing tool has at least one spaced apart and rotationally fixed to the support plate guide plate, through which the at least one brush is guided with their freely emerging bristles. Between at least one brushing tool and at least one workpiece to be deburred, a translatory relative movement can be carried out at least temporarily at the same time for rotational relative movement.
  • the known brushing tool sits to adjust the distance to the surface the workpiece to be deburred on an adjustable slide. If the brushing tool has to be retracted for a brush change or for deburring workpieces of different heights, a second slide is necessary for the adjustment of the guide disk
  • a brush head for deburring and brushing machines in which a drive shaft of the machine is torsionally connected to a base plate in which a plurality of coaxial with the drive shaft arranged, finger-like brushes are held.
  • a guide plate Parallel to the axially displaceable base plate, a guide plate is arranged on the same working shaft, protrude through the brushes with a free stocking length.
  • the brushes are rotatably mounted in the base plate and driven at a speed whose ratio to the speed of the brush head is a maximum of about 1:50.
  • the invention is therefore based on the object to provide a deburring device of the type mentioned, which allows both a feed movement of the guide disc and a mobility of the entire brushing tool with little technical effort.
  • a generic device for deburring a workpiece in which the features of the characterizing part of claim 1 are provided.
  • a first carriage carrying the guide disk and a second carriage carrying the carrier plate are movable along a first or second carriage guide, wherein the second carriage is movable independently of the first carriage but can be moved by it.
  • This construction sets in Advantageously, with known mechanical components to the basic idea of the invention, according to which the carrier plate with the bristle bundles can perform a feed movement relative to the guide disc and the entire brushing tool by moving the first carriage, which entrains the second carriage, can be moved.
  • both the entire brushing tool and the carrier plate with the bristle bundles can be delivered independently of the guide disc. In this way, the wear of the bristle bundles can be compensated by axial feed, whereby the guide disc of the brush tool keeps its distance to the workpiece surface.
  • the brushing tool is arranged displaceable relative to the workpiece to be deburred along the axis of rotation.
  • the entire brushing tool can be moved manually, for example, to either process workpieces of different sizes or to be able to make a change of bristle bundles.
  • stop means are provided, by means of which the guide disc is durable at a defined distance from the workpiece to be deburred.
  • the stop means guarantee easy adjustability of the brushing tool after manual or electrical adjustment to bring the guide disc back to its predetermined optimum distance from the workpiece surface.
  • the stop means are arranged adjustable.
  • the stop can be adapted to the respective workpiece height of a workpiece series to be deburred.
  • the guide disc is rotatably connected to a rotatably mounted in the first carriage drive shaft
  • the support plate is rotatably connected to a rotatably mounted in the second carriage receiving flange, which is slidably connected but rotationally fixed along with him passing through the drive shaft ,
  • the second carriage carries a drive unit, by means of which the drive shaft is set in rotation about the axis of rotation.
  • the drive unit has a motor, a gear and a hollow shaft through which the drive shaft is guided. For non-rotatable connection between the drive shaft and the hollow shaft and the receiving flange while a key is provided in an advantageous manner.
  • a channel system for the supply of coolant and / or lubricant to the at least one bundle of bristles is provided which extends at least partially through the drive shaft and through the guide disc.
  • a device for deburring a workpiece 10, which is positioned on a processing table 20, has a brushing tool 30 rotating about a rotation axis R.
  • the brushing tool 30 comprises a multiplicity of bristle bundles 31 distributed on a pitch circle about the axis of rotation R, which can execute a rotational feed motion V R and / or a translatory feed motion V T relative to the workpiece 10.
  • the bristle ends of the bristle bundles 31 sweep over the surface of the workpiece 10 and thereby carry away burrs and sharp edges.
  • the bristle bundles 31 of the brushing tool 30 are clamped in a support plate 32 with its upper, bound end.
  • the freely emerging ends of the bristles at the lower end of the bristle bundles 31 are guided through bores in a guide disk 33 of the brushing tool 30.
  • the bristle ends project from the guide disk 33 by a predetermined projection, so that by setting and maintaining a constant distance d between the guide disk 33 and the surface of the workpiece 10, an optimum machining result is achieved.
  • the setting of this optimal distance d is achieved by fixing an adjustable stop 43 for a first carriage 40, which is approximately manually along a first slide guide 41 and movable, the guide plate 33 via a drive shaft 42 carries.
  • the support plate 32 of the brushing tool 30 can execute a feed movement Z independent of the guide plate 33, parallel to the axis of rotation R.
  • the support plate 32 is rotatably connected to a receiving flange 52 which is supported by a bearing 53 by a second carriage 50.
  • the second carriage 50 is along a second slide guide 51 - for example by means not shown drive means - independently of the first carriage 40 movable.
  • the first carriage 40 is manually moved upwards, the second carriage 50 being taken along by the first carriage 40.
  • the second carriage 50 also carries a drive unit comprising a motor 54, a gear 55 and a hollow shaft 56 which is penetrated by the drive shaft 42.
  • the drive shaft 42 also passes through the receiving flange 52 of the second carriage 50 and the support plate 32.
  • the hollow shaft 56 transmits its torque via a key 60 on the drive shaft 42, which in turn passes on the key 60 a torque on the receiving flange 52.
  • the keyway allows axial displacement of the first carriage 50 with its components relative to the first carriage 40.
  • a channel system 70 for the supply of coolant and / or lubricant K / S is provided, which extends within the deburring device according to the invention.
  • the drive shaft 42 is designed as a hollow shaft with an axial channel 70, in which coolant and / or lubricant K / S is fed approximately by a rotary distributor, not shown.
  • the lower end of the drive shaft 42 close within the guide disc 33 extending radial channels 70, through which the cooling and / or lubricant K / S is conveyed outwards to the bristle bundles 31 driven by the centrifugal force.
  • the coolant and / or lubricant K / S is available directly at the place where the process-related heat development takes place. Incidentally, this takes place independently of the wear of the bristle bundles 31.
  • electromechanical delivery eliminates advantageously a second drive motor and the associated hardware and software. According to the invention a simple mechanical construction is achieved with only one delivery. The space requirement of the solution according to the invention is relatively low.
