Definitions
- the invention relates to a honing tool for machining bores at the end of the bore, for example blind bores, according to the preamble of claim 1.
- Honing tools of this type in which the short honing stones are arranged at the lower end of the tool body, are known for machining blind holes (DE-PS 30 39 467). They are used for pre-machining the hole in the area of the bottom of the hole. Without this preprocessing, the bore would remain narrower in this lower region when machining with honing stones of normal length, because the honing tool cannot extend out of the bore with part of its length there, as at the other end of the bore, during its axial movement.
- the short honing stones can be used simultaneously with longer honing stones, which are then also arranged on the tool body, for the rial ablation are used on the bore wall, or the processing takes place in two successive steps, the bore at the inner end first being widened by means of the short honing stones and then the bore wall being machined over its entire length by means of the honing stones, which in this case are on a second tool can be arranged.
- the simultaneous processing with the short honing stones and the longer honing stones requires a complicated control, so that the processing in successive work steps is easier.
- a tool change is necessary for this, the tool with the short honing stones being exchanged for a tool with honing stones, or a transfer of the workpiece to another work spindle; however, control is simpler and the machining result is better in many cases.
- Machining errors can occur during the pre-machining of the inner bore end using the honing tool with short honing stones because the tool does not have sufficient guidance in the bore and therefore tends to wobble.
- the machined area of the bore is then no longer exactly coaxial to the bore axis.
- the invention has for its object to design the generic honing tool so that the machining accuracy at the end of the hole is improved.
- the object is achieved according to the invention with the characterizing features of claim 1.
- the arrangement according to the invention of the non-cutting guide rails results in additional guidance and inexorable support of the tool in the bore, especially in the area in which the honing stones themselves are not or not sufficiently effective for the guidance, that is to say in the central area of the bore and for blind holes in the area of the upper end of the hole and if the honing stones are arranged at the upper end of the tool, also in the lower area of the hole.
- the guide strips can only be arranged in this area outside the working area of the honing stones and should have a greater length than the honing stones. They expediently extend over the predominant length of the tool body, one end of one of the guide strips lying between two adjacent honing stones.
- the honing stones can be set in the direction of the bore wall by means of a feed device, for example in a manner known per se by means of swivel bars which are pivotably mounted at one end and each carry one of the honing stones at their other end.
- the feed movement of the honing stones distributed over the circumference of the tool body is conical, which results in a distribution of the feed pressure that is favorable for machining.
- the honing stones can also be radially displaced in relation to the tool axis when infeed.
- the guide strips could be arranged above or below the honing stones and in alignment with them, so that additional honing strips could also be arranged on the tool body, each of which can then be see two guide strips or honing stones would extend.
- the guide strips there is provision for the guide strips to be radially displaceable or pivoted independently of the infeed of the honing stones, so that the contact pressure of these strips on the bore wall can be selected and controlled as required.
- Fig. 1 shows a honing tool in the bore of a schematic
- FIG. 4 shows schematically the wall of the bore according to FIG. 3 with dimensions present during processing
- FIGS. 3 and 4 are honing tools for machining the upper end of the bore according to FIGS. 3 and 4,
- FIG. 7 shows a honing tool for machining the bore according to FIG. 6.
- 1 shows a partial section of a workpiece 1 with a cylindrical blind bore 2, at the inner end of which a narrow recess 3 is provided, which directly adjoins the bore base 4.
- a boring is common in blind holes, but not always present.
- material should first be removed from the bore wall in the vicinity of the bore base, so that a processing 5 is formed.
- a hollow cylindrical tool body 10 which is essentially rotationally symmetrical with respect to its tool axis 11 and which is extended at its upper end to form a pin 12 of smaller diameter.
- Radially aligned pins 13 projecting over the circumference of the pin are inserted into the pin, with which the tool is inserted in the manner of a bayonet connection into a schematically indicated tool spindle 14 which belongs to the honing machine (not shown) and drives the tool.
- a plurality of pivot bars 15, in the exemplary embodiment six, are mounted, which are arranged uniformly distributed over the circumference of the tool body.
- the swivel bars 15 each have a short honing stone 17 at their lower end, which is adjacent to the lower tool end 16 and is said to be very wear-resistant.
- diamond honing stones are provided.
- the swivel bars 15 are substantially longer than the honing stones 17 and in grooves 18 of the tool body 10. They are pivotally mounted at their upper ends by means of a bolt 19 each.
- a feed device 22 Inside a central longitudinal bore 21 of the tool body 10 there is a feed device 22 which has a conical body 23 which is fastened to a central pressure rod 24 by means of a cross pin.
- the conical body 23 lies with its outer surface against a surface of an extension 20 of the associated swivel ledge 15 which is formed with the same inclination.
- a guide bar 25 is arranged between each two swivel bars 15, so that six guide bars are thus present in the exemplary embodiment shown.
- Grooves 26 are provided in the tool body for receiving and guiding the guide strips.
- the guide strips have a wear-resistant, non-cutting sliding covering 27 over their entire axial length, which can be made of hard metal, gray cast iron, plastic or another suitable sliding material.
- the guide strips 25 are radially adjustable. For this purpose, they have two conical lugs 28 which interact with a second feed device 29.
- This second infeed device 29 is also located in the central longitudinal bore 21 of the tool body 10 and essentially consists of a hollow push rod 31 which coaxially surrounds the push rod 24 of the Honstein infeed device 22 and has two conical projections 30.
- the rod 31 has between the two conical projections 30 a transverse bore 32 which is from the transverse pin of the conical body.
- Pers 23 of the feed device 22 is penetrated and has an axial extension which allows the axial movement of the push rod 24 independently of the hollow push rod 31.
- the two conical projections 30 rest on the conical surfaces of the projections 28 of the guide strips 25, so that an axial movement of the push rod 31 is converted into a radial movement of the guide strips 25, the guide strips remaining aligned parallel to the tool axis 11.
- the length of the honing stones 17 is dimensioned such that it corresponds approximately to three times the axial length of the recess 3.
- the tool is driven in rotation about its axis 11 and at the same time is moved axially up and down in short strokes, so that the widening 5 is created.
- the recess 3 allows the honing stones 17 to overflow downward beyond the inner edge of the bore wall.
- the honing tool is constantly guided in the bore 2 by means of the guide strips 25.
- a predeterminable contact pressure of the guide strips 25 on the bore wall is generated, so that constant sliding guidance is ensured.
- the length of the guide strips 25 should be a multiple, at least three times the length of the honing stones 17.
- the guide strips 25 should be arranged such that the honing tool is also guided in the upper region of the bore 2.
- the honing by means of the honing stones 17 can be measurement-controlled in a known manner, for which one or more measuring points are to be provided, which are connected to a measuring device stand, which records the dimensional and shape errors of the workpiece bore and, if necessary, triggers a correction control.
- the bore 2 is further processed over its entire length with correspondingly long honing strips which, as usual, can be fed radially and at right angles to the tool axis 11.
- the tool can be exchanged for a tool with honing stones, or the workpiece can be transported to another tool spindle of the machine, where a correspondingly designed honing tool is available.
- the tool can also be designed such that the guide strips 25 can be exchanged for honing stones, so that after completion of the preprocessing, only honing stones have to be used instead of the guide strips and processing can then be continued with the same tool.
- FIG. 3 schematically shows a workpiece with a bore 6 which runs obliquely to its end face, the bore axis 11A thus, as can also be seen from FIG. 4, runs obliquely to the plane 8 in which the upper limit of the bore 6 lies.
- This bore is machined with the honing tool according to FIG. 5, which largely corresponds in structure to the tool according to FIG. 1.
- the tool also has swivel bars 15A, which, however, are pivotably mounted at the lower end of the tool body 10A and each carry a honing stone 33 at their upper end. Since the honing stones have to work with an overflow at the upper end of the bore, alf-o with each upward stroke of the tool with about a third of their length extend out of the hole, they can not support themselves evenly on the hole wall; As shown in FIG. 5, the bore wall on the side opposite the honing stone 33 shown is shorter, so that the honing stones present (not shown) there have to extend much further out of the bore than the honing stone 33 shown.
- This mode of operation is self-evident Lich also in the usual machining with long honing stones with which the bore is machined over its entire length.
- the honing tool according to the invention serves for pre-honing the upper end of the bore and is therefore provided with the short honing stones 33, which was previously not customary when machining bores in the upper end region.
- the tool is held in its position coaxial to the bore axis by means of the guide strips 25 which, in the exemplary embodiment, extend over almost the entire length of the tool body 10A to its lower end.
- the guide bars 25 are first hydraulically advanced, so that the delivery device 29 with the two cones 30 is adjusted downward under the action of hydraulic pressure.
- the honing stones 33 are advanced, for which purpose the adjusting device 22A is also moved downward.
- This infeed can also be carried out hydraulically, but also mechanically, and a conventional step infeed can be provided.
- the hole is then machined at the top with short strokes, due to the arrangement of the Honing stones 33 on the swivel bars 15A produce a conical widening at the upper end of the bore, as indicated by the broken line in FIG.
- FIG. 7 shows a honing tool which is intended for machining the bore according to FIG. 6.
- This tool is shown in a blind hole 7, honing stones 17 corresponding to the embodiment according to FIG. 1 also being provided at the lower end of the tool body 10B, but here they can be fed radially parallel to the tool axis 11B.
- honing stones 17 corresponding to the embodiment according to FIG. 1 also being provided at the lower end of the tool body 10B, but here they can be fed radially parallel to the tool axis 11B.
- the tool can also be designed such that only the upper end of the bore is machined.
- the honing stone carriers 36 are adjusted by the two cones of the infeed device 38, while the cone of the middle infeed device 37 has guide strips 35 assigned.
- These guide strips 35 also have a sliding coating 35A. They extend up to about the working area of the upper short honing stones 34. The guide strips are therefore effective in the area below the bore end, which has the uneven narrowing.
- the guide strips 35 are initially fed in, so that the tool is supported coaxially to the bore axis in the middle and lower part of the bore.
- the honing stones 36 are fed in, and the honing stones 34 can machine the upper end of the bore with short strokes until the bore diameter there has approximately reached the finished dimension.
- the bore is then honed to the finished dimension using a conventional honing tool.
- the lower end of the bore is simultaneously pre-machined by means of the honing stones 17, in accordance with the working method of the tool according to FIG. 1.
- This pre-machining with parallel movement of the honing stones 17 to the tool axis 11B also leads to a good result of pre-honing in the vicinity of the bottom 4 of the blind hole.
- Such a parallel delivery is also suitable for the tool according to FIG. 5.
- any type of double infeed is suitable for the delivery of the guide bars and the bars carrying the honing stones. Such deliveries are known in the prior art in various designs.
- the double feed device 37, 38 according to FIG. 7 can be designed such that the guide strips 35 do not just have a cone body is assigned, but - in the same way as for the strips 36 - two cone bodies for the feed device 37 are provided in order to ensure a precise parallel alignment of the guide strips 35 to the tool axis 11B.
- the distribution of the honing stones and the guide strips over the circumference of the honing tool also corresponds in the embodiments according to FIGS. 5 and 7 to the illustration in FIG. 2.
- a rigid support of the guide strips on the bore wall is provided, for example by applying a hydraulic medium to the delivery device.
