Definitions
- the invention relates to an ultrasound-excited natural-frequency vibrating honing tool with a free length that is equal to the integer multiple of half the wavelength of the ultrasonic vibration, and with a cutting agent coating, the contour of which, when excited, viewed from the free end of the honing tool, a conical area and then on has a cylindrical region.
- the invention further relates to a method for readjusting such a tool when worn.
- Such a honing tool is described in the international application PCT / EP91 / 02064. Individual features are already known from DE-OS 39 19 895.2-14.
- the above object is achieved in that the rest contour of the cutting agent coating is determined in deviation from the working contour in such a way that the working contour results from the holding contour in the case of ultrasonic excitation, taking into account the amplitude of the vibration component in the radial direction.
- these high-frequency honing tools can also be used for non-circular shapes, e.g. for machining oval bores, trochoids or internal gears. These tools are then no longer rotated, as is the case with honing, but only ultrasonically excited and inserted lengthways into the non-circular inner shapes.
- FIG. 1 shows the embodiment of Figure 1 in
- FIG. 3 shows another embodiment in the
- FIG. 5 shows another embodiment.
- FIG. 1 shows a honing tool 1, which sits with its upper end formed by an outer cone 2 in the inner cone 3 of a sound transmission body 4, which is part of a spindle arrangement 5.
- This spindle arrangement includes a housing 6, which is driven in rotation via a toothed wheel 7 and a toothed belt 8.
- the gear wheel 7 is seated on a rotatably mounted shaft end 9.
- the spindle arrangement 5 together with the (not shown) rotary drive of the toothed belt 9 can be moved up and down on a vertical guide, so that the honing tool can simultaneously perform a rotary and a lifting movement, as indicated by the arrows 10, 11.
- quartz crystals (piezoelectric elements) 12, 13 are arranged, to which the excitation voltage is supplied via a line 14, which is led out through an opening in the housing 6 and is in turn supplied with the required alternating voltage via slip rings.
- a balancing mass 15 is arranged above the quartz crystals.
- FIG 2 shows the honing tool 1 in an enlarged view.
- the cutting surface 20 should have a defined working contour K ⁇ in the working state, ie with ultrasonic excitation, namely with a relatively long cylindrical area Kg and an adjoining conical area K ⁇ .
- This working contour K ⁇ is drawn out in Figure 2 on the left outside next to the honing tool.
- This working contour means that when the tool penetrates a hole in a workpiece, it is first guided with the conical area K ⁇ and then with the cylindrical area Kg carries out the actual machining with a forward and a backward stroke.
- the pressure piece 140 projects into its front end, which is designed as a mandrel 140 ' Opening 121 "into the bore 121. Following the front end 140 ', the pressure piece 140 has a step-widened cylindrical part 140 ".
- this cylindrical part 140" does not cover the entire end face of the front end of the honing tool 100, but is only widened to such an extent that there is no problem Introduction of the force exerted by the hydraulic pressing device 141 into the honing tool 100 results, however, in such a way that in the honing tool 100 itself Shear stresses arise which are reduced by plastic deformation in the radial direction and thus an expansion of the honing tool to compensate for wear.
- a tool such as can be used for machining non-circular shapes, for example, without a rotary movement, is shown in FIG.
- the tool consists of a clamping cone 150 and a tool body 151.
- the transition contour between clamping cone 150 and tool body 151 is almost rectangular.
- Other possible transition contours are shown in Figure 5 on the left at (a).
- the resulting amplitude over height is shown at (b).
- the length of the tool is half the wavelength of the exciting ultrasonic oscillation.
