Definitions

  • the invention relates to a deburring device with a rotatably driven work wheel and a deburring wheel which sweeps over the edge of the end face of the work wheel and which can be set in the radial direction on the work wheel and rotates around a parallel axis of the work wheel in deburring operation, the deburring wheel being subjected to force in the axial direction and when approaching the work wheel due to an inclined edge control by the edge of the work wheel against the force application in the axial direction.
  • the deburring disk has a frustoconical shape, with the base facing the end face of the work wheel. From the base there is an approximately circular section, the base of which forms an inclined flank.
  • Such deburring devices are used to shear off the burr that has formed on gearwheels after gear cutting and subsequent pressing by means of a spinning wheel. After clamping the work wheel in the parked position of the deburring disc, it must be aligned so that the chamfer with its sloping flank is exactly opposite the work wheel. Then the deburring disc is fed in radially, whereby when deburring onto the work wheel, the deburring disc dodges in the axial direction via the bevel flank control. The deburring disc must stop during this process.
  • DE 20204908 U1 describes a deburring wheel with cutting edges which extend essentially in the radial direction or in a direction intersecting the circumferential line. These cutting edges formed by teeth can have a cross-sectional contour that corresponds to the cross-sectional contour of the gear to be deburred.
  • the deburring tools shown there are used in particular for deburring sprockets.
  • the object of the invention is based on the task of simplifying the construction of a generic deburring device and improving the cutting performance.
  • the deburring disc rotates as soon as it is delivered.
  • shorter machining times can be achieved when deburring the work wheel.
  • the burr pushed out of the tooth gaps of the work wheel can therefore be sheared off the deburring disk for a short time.
  • Due to a cutting edge arrangement extending over the entire circumference of the deburring disk the service life of the deburring disk is also increased.
  • the construction of the device can be made more economical in terms of construction, since in comparison to the prior art, positioning is eliminated. Accordingly, savings in construction costs, mechanics, pneumatics, electrics and program control can be realized. There are also shorter or shorter changeover times.
  • two deburring disks arranged one behind the other in the axial direction are provided for simultaneous deburring of the end faces of the work wheel pointing away from one another.
  • the deburring disks shear off the primary burrs which protrude from the end faces and which are pressed out of the tooth gaps by means of a pressure wheel.
  • secondary burrs often occur within the tooth gaps.
  • the measure can be taken that the deburring disk can be driven by the work wheel as a result of a toothed engagement of a smoothing wheel with teeth of the work wheel.
  • the smoothing wheel thus fulfills a double function: on the one hand it serves to drive the deburring wheel and on the other hand to eliminate the secondary burr located within the tooth gap.
  • the deburring disc forms a cutting edge on both broad sides with the inclined flank surrounding it. It can therefore be used as with indexable inserts. Optimal cutting behavior of the deburring disc results from an inclined free flank surrounded by the cutting edge in the radial direction.
  • the deburring disk In order to achieve a particularly long service life of a deburring disk, it is provided as a further and independent object of the invention that it consists of ceramic material. This also leads to the advantage that the burrs sheared off by the ceramic deburring disc are not magnetic. As a result, chips adhering to magnetic force are not present, which largely solves the problem due to chips adhering and being rolled over.
  • the deburring disk is dimensioned such that its free flank angle is approximately 2 °. Furthermore, the inclined flank angle extends in the range from 15 to 45 °, preferably 20 to 40 ° or 30 + 5 °.
  • the cutting edge runs on a circular arc line around the axis of rotation of the deburring disk. It is also possible for a large number of cutting edges to be provided. These can run parallel, that is to say in particular be arranged on concentric circles around the axis of rotation. In a further variant, it is also provided that the cutting edges are inclined or transverse to a circular arc line around the Axis of rotation. Then the cutting edges can be the ridge lines of teeth that extend in the radial direction or obliquely to the radial direction.
  • the deburring disks can be advanced to the respective work wheel in any desired rotational position in the radial direction, the inclined flank of the deburring wheel running on an edge of the work wheel so that the deburring disk is displaced in the axial direction, in particular one the deburring disc is clamped onto the spring acting on the broad side flank of the work wheel.
  • a deburring device has two deburring disks for simultaneous machining of the two broad side surfaces of the work wheel pointing away from one another. When the pair of deburring wheels are delivered to the workpiece, they are moved away from each other. All of this can be done with rotating deburring discs.
  • the sloping flank lies on a truncated cone surface.
  • the deburring disc is preferably actively rotated. This rotary drive does not need to be switched off when changing the workpiece.
  • the invention also relates to a method for deburring workpieces, in which the deburring wheel is continuously driven in rotation during the workpiece change and is fed to the workpiece in a rotating manner.
  • FIG. 1 shows a deburring device, shown schematically partly in longitudinal section and partly in view
  • Fig. 2 is a plan view of Fig. 1; 3 shows an enlarged view of a section of the edge region of a deburring disc designed according to the invention when brushing an end face of the work wheel;
  • FIG. 5 shows the broad side view of a deburring disk of a further exemplary embodiment, in which a plurality of cutting edges extend essentially in the radial direction;
  • Fig. 6 is a section along VI-VI in Fig. 5;
  • Fig. 7 is an enlarged section along the line VII-VII in Fig. 6 and
  • Fig. 8 is a section along the line VIII-VIII in Fig.5.
  • the deburring device according to the first embodiment according to FIGS. 1 to 3 is designated as a whole by the number 1.
  • a work wheel 3 is rotatably seated on an axis 2 thereof. With regard to the same, it is a spur gear.
  • the spur toothing can be designed in the form of a helical or straight toothing.
  • a further axis 4 extends parallel to axis 2.
  • Two press wheels 5 of known construction sit on this, the teeth of which engage in the tooth gaps of the work wheel 3 and produce primary burrs projecting over the end faces 6, & of the work wheel 3.
  • Deburring disks 7, which in turn are arranged on a receptacle 8, serve to eliminate the same.
  • the latter extends diametrically opposite the axis 4 and can be displaced in the double arrow direction x in order to allow the deburring discs 7 to be moved in and out.
  • the deburring disks 7 which serve to simultaneously deburr the end faces 6, 6 'of the work wheel facing away from one another are acted upon in the axial direction, in each case in the direction of the end faces 6 and 6 1 assigned to them. The force is applied by means of compression springs, not shown.
  • Each deburring disk 7 is secured against rotation against the receptacle 8 and interacts with a smoothing wheel 9 each. Their thickness corresponds to approximately half the thickness of the work wheel 3. Both smoothing wheels 9 are firmly connected to the receptacle 8.
  • the deburring discs 7 can shift slightly in the axial direction relative to the smoothing wheels 9.
  • the smoothing wheels 9 are provided with a toothing which engages in the spur toothing of the work wheel 3.
  • the smoothing wheels 9 have the task of eliminating any secondary burrs generated by the pressure wheels within the tooth gaps.
  • Each deburring disk 7 sweeps over the edge of the end face 6 or & of the work wheel 3, specifically beyond the tooth base of the tooth gaps. This sweeping takes place by means of an edge-side cutting edge 10 of the deburring disk 7.
  • the deburring disks 7 are arranged in such a way that when the deburring disks 7 are parked, the parallel distance between the cutting edges 10 of two opposing deburring disks 7 is less than the thickness of the work wheel 3 the deburring discs 7 are delivered, so according to an inclined edge control by the edge R of the work wheel 3, the deburring discs 7 deflect against the force of the springs acting on them.
  • the displacement of the deburring discs 7 towards one another is limited so that the inclined edge control can take effect. In the exemplary embodiment, this is done by the smoothing wheels 9, which cannot be displaced in the axial direction.
  • each deburring disc 7 has an uninterrupted, over the entire circumference of the deburring disc 7 extending inclined flank 11.
  • the inclined flank angle ⁇ extends in the range from 15 to 45 °, preferably 20 to 40 ° or 30 + 5 °. In the present case, an inclined flank angle of approximately 30 ° has been selected. Due to this inclined flank angle ⁇ , the deburring disk 7 is shaped like a truncated cone over part of its length.
  • the aforementioned oblique flank angle ⁇ is the angle which the oblique flank 11 forms with the axis or shaft 8. As the drawings illustrate, the inclined flank 11 is delimited by the cutting edge 10 in the end area of the work wheel 3.
  • the head edge R of the work wheel 3 extends at the level of the inclined flank 11, so that when the deburring disc 7 is delivered, the inclined flank 11 acts as a run-up slope.
  • the end of the oblique flank 11 opposite the cutting edge 10 continues at an obtuse angle, so that the deburring disc 7 is composed of two truncated cone sections with their bases facing each other.
  • each deburring disk 7 has an inclined free flank 12 which is surrounded by the cutting edge 10 in the radial direction.
  • the free flank angle ⁇ is approximately 2 °. Due to this design, an optimal stability of the deburring disk 7, which is preferably made of ceramic material, is achieved.
  • the ceramic deburring discs 7 also have the advantage that the sheared chips are not magnetic and largely preclude a roll over of chips. However, it is possible to choose metal as material for the deburring discs, such as tool steel, etc.
  • each deburring disk 13 has a cutting edge 10 on both broad sides, with the inclined flank 11 surrounding it is a free flank 12 upstream of each cutting edge 10. In this way, a reversible deburring disc 13 with a long service life is produced.
  • the cutting edge does not run on a closed circular arc line around the axis of rotation 8.
  • the deburring disc 14 has a plurality of cutting edges 10 which extend essentially in the radial direction.
  • the cutting edges 10 run obliquely to a circular line 16 about the axis of rotation 8 and are arranged along this circular line 16.
  • the cutting edges 10 are formed by the ridge lines of teeth 15 and are located within the line 16, that is to say they are delimited by this.
  • the inclined flank 11 which extends on a conical surface on the periphery of the deburring wheel 14, also forms a control flank here, on which, when the deburring wheel is fed radially, an edge of the workpiece 3 runs around the deburring wheel 14, as described above, in the axial direction against the To shift restoring force of a compression spring, not shown.
  • the control flank 11 running on a truncated cone surface extends between the two circular arc lines 16 and 17 over the end flanks of the teeth 15
  • Bevel angle ⁇ is in the ranges described above.
  • the distances between the individual cutting edges 10 are so small that the outer contour line 17 can lie in the region of the teeth 15. It is essential that the length of the inclined surface 11 in the axial direction or in the radial direction is so great that an infeed to the work wheel 3 is possible in any rotational position of the deburring disk 14.
  • the deburring disk 14 is made of ceramic, since this material allows a longer service life and is not magnetic. Nevertheless, it is also envisaged that the material of the deburring disc can be steel. The material can in particular be an HSS tool steel.
