  • a tool or its tool holder When, for example, taking a hole in the workpiece 10 in the axis z of the spindle, a tool or its tool holder is moved along the axis z of the spindle, whereby the hole will extend in the same direction and along the same axis. If a so-called angluar hole is to be opened, i.e. a hole is drilled, which will extend at an angle relative to the axis z of the spindle, it is used a special tool holder which has an arranged drill which is set at a fixed angle and direction or is setable at a given angle and direction.
  • one and the same tool holder is used for all holes which are meant to be opened and show same dimension or diameter and irrespective at which angle the hole is meant to extend in the workpiece 10.
  • This is realized by the fact that the tool 6 is brought to contact or engagement with the workpiece 10 and in the axis 11 of the tool holder 2. After that the tool holder 2 is brought to further movement in the direction of the axis 11 or the axis z of the spindle at the same time as a movement is carried out along the axis x and/or the axis y.
  • a pilot mark 19 is arranged in the workpiece 10 and with which the tool 6 is made to engage before the adjustment and taken the intended position at an angle.
  • the joint 5 is schematically evident from Fig. 3 as well as the axes of rotation 13 and 15 respectively, which thus extend at right angles to each other.
  • the joint 5 can be shaped as a universal joint, in which the parts connected with the joint can turn relative to each other in any direction and in any case to a relative turning of nearly 90 or approx ⁇ imately 90 .

  • the guiding device 7 is arranged in such a way that it allows the said second part 4 of the tool holder 2 to turn relative to the said first part 3 of the tool holder 2, when the tool 6 is arranged in contact or in engagement with a workpiece 10 or a pilot mark 19 in the workpiece 10 and the tool holder 2 is brought to move besides along a first axis z or the axis z of the spindle, also along a second axis x and/or a third axis y.
  • the guiding device 7 can be shaped as a holding means 14, for example in the shape of a sleeve, which is arranged co-axially about the said second part 4 of the tool holder 2 and is dis- placeably arranged upon it against the action of a spring means 9, as a helical spring extending about the said second part 4 of the tool holder 2.
  • the said second part 4 of the tool holder 2 is shaped with a stop 8, shoulder, collar, flange or similar, against which the spring 9 rests.
  • the holding means 14 shows also a stop 16 for the spring 9, for example in the shape of a projecting flange, shoulder, collar or similar, whereby the spring 9 is arranged tighten between the stop 8 on the said second part 4 of the tool holder 2 and the said stop 16 of the holding means 14.
  • the holding means 14 shows an end portion 17 or an end surface, which is shaped to strike against the said first part 3 of the tool holder 2 or its end portion 18 or end surface, and by the influence of the spring 9 is arranged to hold by guiding the said second part 4 of the tool holder 2 in the axis 11 of the tool holder.
  • the said first part will force the hold ⁇ ing means 14 away against the action of the spring 9.
  • the said second part 4 of the tool holder 2 will automatically return to the original position and take an extension along the axis 11 of the rest of the tool holder 2. This is caused by the influence of the spring 9 and its effect on the holding means 14 , which guides the said second part 4 of the tool holder 2 back to the original position and extension along the axis 11 of the tool holder 2.
  • the guiding device 7 or the holding means 14 take again its position where it holds and guides the said second part 4 of the tool holder 2 in the axis 11 of the tool holder 2 and its its end portion 17 or end surface rests against the said first part 3 of the tool holder 2 or its end portion 18 or end surface and guides and holds in that respect the said second part 4 of the tool holder 2 in the axis 11 of the tool holder 2 or in the axis z of the spindle.
  • the machine can move the holder 2 with the drill 6 in a direction along the said first axis z or the axis of the spindle and at this open a recess or a hole in the workpiece 10 in one direction, which thus is coincident with the said first axis z, the axis of the spindle or the axis 11 of the holder 2.

Abstract

Lorsqu'une pièce doit être pourvue d'évidements ou de trous au cours de l'usinage par machine, une première partie (3) d'un support (2) est connectée à la broche de la machine. Une seconde partie (4) du support porte un foret (6). Le support (2), soutenant le foret (6), s'étend le long d'un premier axe (2) ou le long de l'axe de la broche de la machine. Cette dernière peut déplacer le support (2) et le foret (b) en une direction le long dudit premier axe (2) ou de l'axe de la broche, afin de pratiquer un évidement ou un trou dans la pièce (10), en un sens correspondant audit premier axe (2), à l'axe de la broche ou à l'axe (11) du support (2). Lorsqu'un évidement ou un trou doit être pratiqué dans la pièce (10) et doit s'étendre à un angle par rapport au permier axe (2) ou a l'axe (11) du support, la seconde partie (4) du support (2), ainsi que le foret (6), sont pivotés par rapport à la première partie (3) du support (2), à un angle (x) et/ou (y) correspondant au sens (12) d'usinage prévu pour le foret (6), c'est-à-dire à l'angle auquel l'évidement ou le trou doit être pratiqué dans la pièce (10).
