Definitions
- the present invention belongs to the field of drilling materials and more particularly to drilling deep holes by means of cutting tools.
- the tool In order to split the chips produced by the cutting tool, the tool is regularly released from the material by an axial backward movement relative to the direction of progression of the bore before continuing the progression in the drilling direction.
- a first technique consists in forcing an axial movement of periodic recoil of the tool, superimposed on the direction of movement of the drilling progress, by a suitable mechanism, but this imposed movement generates, when the tool returns in contact with the material to continue the drilling, repeated shocks that cause rapid degradation of the characteristics of the tool.
- a second technique described in the French patent application published under the number 2,765,505 consists in fixing the tool on a tool holder coupled to a drilling head comprising means for axial guide of the tool holder relative to the support of the piercing head and translational linkage means deformable in axial translation so that the tool can vibrate in the axial direction under the effect of the forces generated by drilling.
- the axial guide means maintain the axis of the tool coincides with the axis of the piercing head.
- These means take the form of two rings spaced along the axis of the piercing head and which deform in the direction of the axis without allowing radial movements or variation of the direction of the axis of the tool relative to to the axis of the piercing head.
- these axial guiding means comprise a ball slide integral with the piercing head in which the tool holder slides in the direction of the axis of rotation, also without allowing variation between the direction of rotation. axis of the tool and that of the axis of the drilling head.
- Such means are mechanically complex and lead to a significant increase in the dimensions and fragility of the piercing head, in particular because of the vibrations maintained by the device and the sensitivity of the axial guide means to radial forces.
- the guiding means are sources of friction which disturb the self-maintained vibratory operation which is very sensitive to changes in the parameters of the device and the said guide means require the production of specific drilling heads which may require major modifications of the drilling devices and machining ranges associated with holes.
- the present invention provides a self-sustaining axial vibration drilling device for the generation of short chips which makes it possible in particular to use the 3 A drills without difficulty for the production of high precision drillings and which comprises simple and robust means that can be adapted to most existing machines to perform this type of drilling.
- a drilling device comprises
- a rotary drive unit comprising an output shaft driven in rotation about an axis
- a cutting tool with an axis of rotation; means for coupling the cutting tool with the output shaft;
- the coupling means are adapted to transmit the driving torque to the cutting tool and comprise elastic means arranged to cause a self-sustaining axial vibration of the cutting tool during a drilling operation.
- the coupling means are arranged to allow an angular difference between the direction of the axis of the cutting tool and the direction of the axis of the output shaft under the effect of radial forces applied to the tool. cutting during the drilling operation to avoid the hyperstatic configuration that would be generated by a mounting of the tool in which the direction of the axis of the tool would be imposed relative to the direction of the drive shaft.
- the coupling means comprise a first end element provided with means coupling to the output shaft of the drive unit, a second end member provided with means for securing the tool and having an intermediate zone between said first and second end members, rigid torsionally elastic in an axial direction and flexible in flexion.
- the intermediate zone comprises first torsionally rigid, flexible means in the axial direction and flexible flexion and comprises second means, separate, resilient in the axial direction.
- the first means of the intermediate zone comprise at least three arms arranged non-radially between a first ring secured to the first end member and a second ring integral with the second end member.
- Spring means capable of being compressed between bearing faces of the first and second end members cause the self-sustaining axial vibration of the tool.
- the first and second end members and the means of the intermediate zone are shaped to avoid direct contact between said first and second end members during the drilling operation.
- the intermediate zone comprises an elastic element in an axial direction, which is also able to transmit the torsional forces of the bore and able to deform in bending during the rotation of the tool to allow the axis said tool to have a different direction of the axis of the output shaft.
- Such an elastic element along an axis and able to transmit the movement of the tool when said tool is not aligned with the drive shaft advantageously comprises at least three coaxial rings of elastic material having substantially the same dimensions and arranged according to a battery.
- Each ring is spaced from the adjacent ring and is connected to said adjacent ring by means of two connecting elements arranged along a radius of the rings and radially opposite, and where the two connecting elements disposed on a face of a ring are further arranged along a radius substantially perpendicular to the radius defined by the two connecting elements disposed on the other side of the ring.
- rigid in torsion about an axis corresponding to the axis of the crowns the deformation of the crowns provides the desired axial elasticity while the deformation of the links allows deformation in flexion.
- the intermediate zone comprises at least two coaxial-held crowns spaced apart by at least two elongate connecting elements of elastic material, each connecting element being fixed to a first ring by one end of said connecting element and being fixed to the second ring by a second end of said connecting member at an offset point, an angle corresponding to an angle of rotation of the rings about their axis, from the point at which the first end is fixed to the first ring.
- the bending deformation of the connecting elements ensures the desired elasticity along the axis and the flexibility required for bending deformation.
- a metallic material such as a steel is used for its properties as elastic material and the intermediate zone and the end zones are made in a single element by machining a block of material.
- the invention also relates to a cutting tool for drilling which comprises:
- a first cutting end comprising an axis of rotation, capable of producing a chip-removing bore of the material to be pierced, a second end comprising an axis of rotation intended to be coupled to rotational drive means; around said axis, and which comprises between the two ends a connecting zone:
- FIG. 1 an exemplary drive means principle which is coupled to a cutting tool and having a tool feed device
- 2 an example of a first embodiment of means for coupling the cutting tool to an output shaft of the drive means, with FIG. 2a a sectional view of the assembled coupling means and FIG. exploded in perspective of the elements of said coupling means

- FIG. 5 an example of a second form of the intermediate zone with a perspective detail of an intermediate zone of said means - Figure 5a -, and a developed view of the surface of said intermediate zone showing an example of shape of the openings on the outer surface of said intermediate zone - Figure 5b -; - Figure 6: a view of a tool according to the invention.
- a self-sustaining axial vibration drilling device comprises drive means 1 comprising an output shaft 2 rotated by said drive means about an axis of rotation 3.
- a cutting tool 5 of axis of rotation 6 is fixed by means of a tool support 7 so that the axis 6 of the tool is substantially in the extension of the axis 3 of the output shaft and the tool 5 is rotated by the rotation of the output shaft 2.
- the tool 5 is moved in an axial movement so that an end 51 of said tool enters the part 8 in which the drilling must be performed.
- This displacement D or movement in advance, is performed by an advance device 9 of the drive means which ensures the controlled displacement of the end 4 of the output shaft 2 relative to a support structure 11 of the training means.
- the advance movement can also be achieved by a relative movement between the part 8 and the drive means 1.
- the tool support 7 comprises a first element 71 adapted to be fixed by an end 712 to the output shaft 2 driving means 1 to be rotated and comprises a second member 72 adapted to maintain by one end 724 the end of the cutting tool 5 opposite the end 51 which enters the room 8.
- Said first and second elements 71, 72 cooperate by means of a third element 73 comprising an outer ring 74 and an inner ring 75 connected by at least three arms 76.
- the outer ring 74 is integral with the first element 71, for example by means of screws 731.
- the inner ring 75 is secured to the second member 72, for example by means of a clamping nut 732.
- the axis 3 of the output shaft 2 when the end 412 first member 71 is attached to said output shaft, and the axis 7 of the tool 5, when attached to the end 724 of the second member 72, is substantially aligned.
- the at least three arms 76 connecting the rings 74, 75 are arranged substantially differently from the spokes, that is to say that they do not converge towards a common point in order to be able to rotate the second element 72 by the arms 76 during the rotation of the first element 71 so that said arms are biased essentially in traction to increase the transmittable torque and so that the second element 72 can firstly move in an axial translational motion by relative to the first element 71 and can on the other hand move in an angular movement so that the axis 7 of the tool, when the tool is mounted on said second element, and the axis 3 of the output shaft when said first member is connected to said shaft, may have different directions during the rotational movement about the axes 3, 7 of the output shaft and the tool.
- the at least three arms are made of a material, for example a steel, having the characteristics of mechanical strength and flexibility to transmit the rotational forces and to undergo the necessary deformations taking into account the amplitudes sought for axial and angular movements.
- the amplitudes which vary according to the dimensions of the device, are most often of the order of a few tenths of a millimeter for the axial displacements and less than one degree for the angular displacements.
- Elastic means 77 for example a spring working in compression, are arranged between the first and second elements 71, 72. Said elastic means bear on a face 711 of the first element and on a face 721 of the second element.
- the second element 72 to which the tool is attached moves in one direction opposed to the advance D of the tool by deforming the arms 76 of the third element 73 and compresses the elastic means 77 between the bearing faces 711, 721 of the first and second elements.
- the elastic means 77 are held in position substantially in the axis of the first and second elements 71, 72 by means of a protuberance, for example a protuberance 722 of the second element 72 substantially in the axis of said element, around which are placed the elastic means.
- the shape 722 allows the relative movements of axial and angular translations between the first and second elements without interference. Games 723 are in particular left between the first and second elements 71, 72 so that the movements of axial translations are carried out without friction and that the angular movements do not generate any risk of jamming.
- the orientation of the axis 6 of the cutting tool 5 is not imposed by the drive means which comprise no axial guidance of the tool, the end 51 of the tool on the side of the part 8 to drill is guided.
- the guidance is carried out for example by means of a drilling barrel 10 which is positioned relative to the piece 8 to be pierced by means of a support such as a piercing grid (not shown).
- the guidance is achieved by means of a partial drilling of the workpiece for centering and initial guidance of the cutting tool 5 which is then guided during drilling by the hole in progress.
- the choice of cutting parameters, tool rotation speed and feed in particular, and a suitable stiffness of the elastic means 77 causes an axial vibration of the cutting tool maintained by the efforts of the cut and the natural instabilities of drilling.
- the mass of the moving assembly is a parameter which influences the vibratory conditions and it may be necessary to adjust the mass of the cutting tool or of the vibrating assembly, for example by means of masses reported, so that the axial vibratory motion triggers and is self-sustaining during a particular drilling operation.
- the chips fractionation can be obtained by an amplitude of the axial vibration such that the tool is momentarily released from the material of the part, which occurs when the tool vibrates along its axis with an amplitude substantially equal to or greater than the distance traveled by the feed device of the tool during a cycle of the axial vibration.
- the chip fractionation can also be obtained with a lower vibration amplitude but sufficient so that the thickness of the chips is sufficiently reduced when the tool is in the least engaged position in the material so that the weakened chips break naturally when the piercing operation.
- the implementation of this vibratory mode of operation is preferred to prevent the tool from being damaged by an entry into the material of the part at each cycle of the axial vibration.
- the photograph of FIG. 3b shows fractionated chips produced during a drilling operation performed with a self-sustaining axial vibration device according to the invention which are compared with the chips of the photograph of FIG. 3a, having substantially the same magnification ratio, achieved during a conventional drilling operation.
- the tool support 7 is made by means of a single element 12 of substantially cylindrical shape.
- the single element 12 comprises at one of its ends 121 means for fixing the output shaft 2 of the drive means 1 and at its other end 122 means for fixing the cutting tool 5.
- said fixing means are compatible with those of the drive means and the existing tools.
- the tool support 12 comprises an intermediate zone 123 shaped to obtain the desired compression elasticity characteristics for the elastic means associated with the displacement. axial vibration of the tool and flexural flexibility characteristics sought to allow the axis of the tool to be deflected at an angle, in particular under the effect of the forces applied to the cutting tool 5.
- This intermediate zone 123 which must also transmit the torsional forces, is advantageously produced by a hollow cylindrical segment of circular section, as illustrated in FIG. 4b, made of an elastic material, for example a steel, and whose wall 130 comprises openings 124 defining a structure of the intermediate zone 123 comparable to a stack of rings 125 maintained spaced apart by spacers 126 mounted in pairs diametrically opposed between two rings and arranged at 90 degrees between the 2 faces of a ring.
- the intermediate zone 123 is made by machining a block of material in which the ends 121, 122 are also machined.
- Figure 4c illustrates the appearance of the outer surface of the intermediate zone 123 developed on a plane. This arrangement allows
- the intermediate element To transmit the rotational movement when the axis 6 of the tool is not exactly in the direction of the axis 3 of the output shaft, the intermediate element operating in this case in the manner of a cardan-type assembly.
- intermediate zone 123 is usable as long as they meet the three requirements of transmission of the drilling torque, elasticity along the axis of the tool and possibility of angular deformation between the axis of the drive shaft and the tool axis.
- Figures 5a and 5b illustrate another possible arrangement openings 127 in the wall 130 of the intermediate zone 123 adapted to restore the desired capabilities for said intermediate zone.
- Figure 5b illustrates the shape of the openings at the outer surface of the intermediate area grown in a plane.
- the intermediate zone 123 comprises at least two rings 128a, 128b connected by material bridges 129.
- Each material bridge 129 is connected to the first ring 128a by a first end 129a and is connected to the second crown 128b by its second end 129b at a point of said second ring offset from the point of connection with said first ring at an angle corresponding to an angle of rotation about the drive axis, for example 90 degrees.
- the tool holder is a conventional and rigid connection means and the means for permitting axial and angular displacements of the tool are integral parts of the cutting tool.
- Such a cutting tool 5, shown in FIG. 6, comprises between one end 5a, capable of producing a drilling by removal of material chips by rotation about an axis 6a, and an end 5b, able to be rotated around an axis 6b by drive means, such as those shown in FIG. 1, a connection zone 5c:
- connection zone 5c comprises means similar to those of the intermediate zone 123 of the tool support described above.
- This embodiment is particularly advantageous because, without it is necessary to modify the existing drive means, on the one hand the intermediate zone 123 is made according to the particular characteristics of the tool and the envisaged cutting parameters, characteristics which influence the self excited vibratory behavior of the tool, and on the other hand the duration of use of the intermediate zone 123 is limited by the service life of the cutting tool to which it is integrated, which has the effect of avoiding or greatly limiting the risk of failure in fatigue of said intermediate zone, strongly stressed in vibration and effort, during the drilling operations.
- Intermediate zone 123 can be made by machining at the time of production of tool 5.
- the tool can also be produced by an assembly, for example by welding, of different elements.
- an intermediate zone similar to the intermediate zone 123 of the tool support described above, is arranged on the output shaft 2, near the end on which is connected a support d tool or tool.
- the invention thus makes it possible to produce holes producing fractionated chips that are easy to remove by conventional means, for example blowing and / or suction, including drills producing non-symmetrical cutting forces with respect to the axis of the blade. drilling, such as drills with a single cutting edge said drills 3 A, without axial guidance of the tool at the drive means of the rotating tool.
- the invention makes it possible to produce self-sustaining axial vibration bores of the tool without modifying the existing drive devices.
