Definitions

  • the invention relates to tool spindles such as those for drills, boring machines, grinding machines, etc. and designed to allow precise work on the parts to be machined, and more particularly on tool-holder spindles for valve seat grinders.
  • Technical ⁇ vtévieuve The current pins have either a fixed sheath, or an oscillating sheath locked by mechanical means, as it is ; case. of the pin described in the French patent no. 562 738 filed by MONPAIN, on 27.2.23. These means have the drawback of leading to insufficiently precise trial and error positioning.
  • English patent n ° 926,072 describes an oscil ⁇ lante spindle thanks to a spherical head capable of being moved between a fixed seat and a mobile seat carried by a piston subjected to the action of a hydraulic fluid.
  • said fluid only intervenes to produce the immobilization of the spherical head between the two seats.
  • FIG. 1 schematically shows a spindle according to the invention applied to a seat grinding machine
  • Figure 2 is a sectional view of this pin in the immobilized position while Figure 3 shows the same pin during the period it floats between the two seats.
  • this spindle (1) provided with the tool holder (1a), to which the tool (1b) is fixed must take any suitable position so that the pilot rod (1c) " which extends the holder tool can be inserted into the guide (GS) of the engine valve (M) so we want to adjust a valve seat (SP).
  • the spindle head (here referenced by that of the housing (3)) is subjected to alternative displacements, in a horizontal plane according to the arrows (f1) and (f2), of the table (T) of which it is interdependent.
  • the bro ⁇ che (1) slides and moves in the sleeve (2) comprising a nut having two spherical parts (2a-2b).
  • This nut is enclosed in the housing (3), subject to the movements of the table (T) as has just been said according to the arrows (f1 and f2), said housing (3) serves as a cylinder for a piston (5).
  • lower part of this housing (3) has a concave part of sphericity suitable for constituting the fixed seat (3a) on which the spherical-lower part can come to rest:.
  • the pi-ston (5) also has a concave portion of sphericity suitable for applying against the upper spherical portion of the barrel nut (2) and serving as a movable seat.
  • the cylinder is completed by a bottom (6) provided with a projection (6a) directed towards the inside of the cylinder and serving as a stop limiting the displacement of the piston upwards, said bottom (6) receiving a pipe (7).
  • the barrel nut (2) has a step (2c) located at a level below the level of the piston (5).
  • FIG. 2 it is the pipe (7) which is supplied from (E) and the pipe (4) which is connected to the open air.
  • FIG. 3 it is the opposite.
