Definitions

  • the present invention relates to a hand tool machine for the making of holes in an object preferably made of composite fibre with a curved surface, whereby the centre line of the hole passes through a predetermined point on the surface of the object and is oriented in a certain direction relative to the longitudinal direction of the fibres in a local surrounding of said point.
  • Polymer composite materials have been familiar since the 1950s. These materials are composed of a protective and consolidating polymer, either thermoplastic or thermo- setting resin plastic, usually referred to as the matrix, and fibres (e.g. glass, carbon or aramide fibres) , which may be regarded as reinforcing material.
  • the fibres may be continuous and oriented in certain directions, or relatively short and arranged at random in the matrix.
  • Composites with continuous and oriented fibres give products with superior mechanical characteristics to conventional polymer and metallic materials, in particular with regard to their weight-related strength and rigidity and have accordingly found widespread applications, for example in the aircraft and space industries.
  • Composite materials for practical applications are often constructed from shells with double curvature, which have been joined to a stiffening sub-structure.
  • a common method of joining is a bolted joint, in which the load is transmitted from one part of the structure to the other via shearing forces in the bolts.
  • the strength of a bolted joint is influenced to a considerable degree by the quality and accuracy of the hole. Reference can be made here to three problem areas which can arise in conjunction with making holes in polymer composite materials:
  • Previously disclosed in two Swedish patent applications, 9201420-8 and 9203493-3 are two methods for forming a transcurrent hole in a fibre-reinforced composite material in such a way that, the aforementioned problem areas are eliminated.
  • a common feature of the two methods is that the opening is formed by causing a material-cutting tool on the one hand to rotate about its own axis and on the other hand to describe an orbital movement relative to the edge of the hole, in conjunction with which the fibre-reinforced material is positioned so that the axis of rotation of the tool is essentially orthogonal to the longitudinal directions of the fibres at the edge of the hole.
  • the object of the invention is to make available a machine in accordance with the introduction, which enables a high- quality making of holes in an object made of composite fibre.
  • this is made possible by the machine comprising the following in combination:
  • a tool holder rotating about its own axis and about a principal axis; a device for adjusting the axis of rotation of the tool holder in the normal direction; a device for axial feeding of the tool holder relative to the object; a device for adjusting the distance between the principal axis and the axis of rotation of the tool holder; and a device for taking up forces and moments between the machine and the object that originate from the making of holes, which forces rotate about the principal axis and on one hand act in a direction that coincides with the axis of rotation of the tool holder and on the other hand act in a plane in the normal direction of to said axis of rotation.
  • Fig. la shows a longitudinal section of a general drawing of the machine
  • Fig. lb shows a cross-section through the machine
  • Fig. 2 shows the machine during the making of holes in a composite material
  • Fig. 3 shows a longitudinal section of a general drawing of an alternative embodiment of a hand tool machine in accordance with the invention.
  • a laminate 1 shown in Fig. 2 consists of a number of laminae (layers) with continuous fibres, which laminae are arranged one on top of the other.
  • the longitudinal directions of the fibres at a random point in the laminate define the tangential plane with the surface of the laminate.
  • a hole template 2 Positioned on the upper surface of the laminate is a hole template 2 in the form of a shaped plate with pre-drilled holes 3.
  • the machine comprises a tool holder 4, which is so arranged as to rotate on the one hand around its own axis 5 and on the other hand eccentrically about a principal axis 6.
  • the first mentioned rotation is a achieved by the axis 5, in relation to the principal axis 6, being eccentrically mounted in two slides 8, which run in grooves 9a in the end walls of the rotor 10.
  • the rotor 10 is driven by a low-speed motor 14 via a gear unit comprising the gear wheels 11, 12, and 13.
  • the last- mentioned rotation is achieved by the tool holder 4 being operatively connected to a motor 14b.
  • the eccentric rotation of the tool holder about the principal axis 6 takes place with a constant distance between the principal axis 6 and the axis of rotation 5 as will be explained in detail in the following.
  • the corresponding movement takes place in linear increments, that is to say not as a rotational movement in the strict sense, which gives rise to a conflict between, on the one hand, the speed of machining and, on the other hand, the accuracy of machining.
  • a numerical solution is associated with significantly higher costs.
  • the machine is executed with a device for adjusting manually the axis of rotation 5 of the tool holder in the normal direction to a tangential plane to the surface of the object.
  • a device for adjusting which, on one hand, comprises a sleeve 15 with three point contacts 17 on the surface of the hole template in an area around the point through which the centre axis 7 of the hole passes, which sleeve is fixed in a desired position and direction with a bolted joint 18, and on the other hand the outer casing 19 of the machine, which casing is arranged to slide into the sleeve 15, whereby the axis of rotation of the tool holder is arranged perpendiculary to the surface.
  • the machine also comprises a device for adjusting the distance L between the axis of rotation 5 of the tool holder 4 and the principal axis 6.
  • this is made possible by causing the axis of rotation of the tool holder to be mounted in the aforementioned two slides 8, which run in radial grooves in the end walls 9 of the rotor 10.
  • the slides 8 are displaced with the help of slide screws 21, which in turn are activated, via an angle drive 22, by a shaft 23 (eccentrict shaft) mounted eccentrically in the end walls 9 of the rotor, the rotational speed of which shaft is adjustable.
  • the eccentric shaft 23 is able to rotate at the same speed as the rotor 10, but in the opposite direction (i.e.
  • the differential shaft 25 is connected to the motor 14a and is driven at a speed n x .
  • the differential shaft 26 is connected to a regulator. In this way the differential wheel 27 adopts the speed n x /2 with the shaft
  • the machine also comprises a device for on the one hand a force rotating about the principal axis 6 and acting parallell to the axis of rotation 5 of the tool holder 4 and on the other hand a force rotating about the principal axis 6 and acting in the normal direction to the axis of rotation 5 of the tool holder 4.

  • this is made possible by means of a bayonet socket 20, which locks the outer casing 19 of the machine in the sleeve 15.
  • the machine comprises a device for the axial feeding of the tool holder 4.
  • this is made possible by executing the inside casing 31 of the machine with two slides 32, which run in grooves 33a in the outer casing 33 of the machine.
  • Axial feeding of the tool holder 4 is obtained by causing the feed screw 34, which is connected to the motor 35, to rotate.
  • the tool holder 4 on the one hand rotates concentrically about the axis 5 under the influence of a motor 36, and on the other hand rotates eccentrically about the principal axis 6.
  • the latter rotation is obtained through the motor 36 being eccentrically suspended from a rotatable spindle motor bracket 36, rotated by a motor 38.
  • the machine is executed with a device for manually adjusting the axis of rotation 5 of the tool holder 4 in the normal direction to a tangential plane to the surface of the object.
  • said adjustment device on one hand comprising a template 39, with a contact surface including an infite number of point contacts on the surface of the object 1 in an area around the point through which the centre axis 7 of the hole passes, and on the other hand the lower part 33a of the outer casing 33 of the machine being provided with a sleeve 40, which is intended to be guided into a pre-drilled hole 39a in the template 39, whereby the axis of rotation of the tool holder is arranged in a desired position.
  • the template 39 is not shown in direct contact with the surface of the object 1 for the sake of clarity.
  • the machine further comprises a device for adjusting the distance (L) between the axis of rotation 5 of the tool holder 4 and the principal axis 6.
  • this is achieved through the spindle motor bracket 37 consisting of a cylindrical, centered inner sleeve 42.
  • the inner sleeve 42 is turnable in relation to the outer sleeve and the distance between the axis of rotation 5 of the tool holder 4 and the principal axis, which causes the distance between the axis of rotation 5 of the tool holder 4 and the principal axis 6 to be variable, owing to that the spindle motor is mounted in the inner sleeve and that the principal axis 6 coincides with the centre axis of the outer sleeve 41.
  • the machine has an arrangement for on one hand the taking up of a force rotating about the principal axis 6 and acting parallell to the axis of rotation 5 of the tool holder 4, and on the other hand the taking up of a force rotating about the principal axis 6 and acting in the normal direction to the axis of rotation 5 of the tool holder 4.
  • the taking up of said forces is made possible in that the lower part of the outer casing 33 of the machine is arranged to be wedged between the template 39 and screws 43 that are mounted in the template 39. Said forces will then be taken up as contact forces (normal and frictional forces) between the lower part of the machine and the surroundings.
  • the axial feeding of the tool holder is made possible through the fact that the attachement means of the two motors are axially displaceable under influence of a hydraulic/pneumatic cylinder 44.
