Definitions

  • Carrier tool for inserts with fine adjustment elements
  • the invention relates to a carrier tool for cutting inserts in a cutting tool according to the preamble of claim 1.
  • the invention is based on the object of substantially improving a carrier tool for cutting inserts with fine adjustment elements according to the preamble of claim 1 with regard to the setting accuracy and the handling.
  • That the fine adjustment element consists of a rotatable bolt (10) with an eccentrically attached surface (12),
  • the center of the eccentric of the eccentric surface is offset from the center of the bolt by 0.1 to 0.5 mm.
  • the bolt advantageously has a slot, hexagon socket, Torx or screw drive on one end face.
  • the bolt preferably has an external thread or a threaded bore.
  • the bolt has a constriction into which a grub screw can be inserted for locking.
  • the grub screw can advantageously be inserted into a transverse bore for the bolt.
  • the eccentrically attached surface makes sense to grind the bolt.
  • the bolt preferably consists of a hard and wear-resistant material such as hardened steel, hard metal or industrial ceramics.
  • the idea of the invention is therefore based on not using a wedge, but a bolt with an eccentric bevel for fine adjustment. Fine adjustment of cutting inserts, in particular in milling cutters for one or more inserts, is one possible application of this invention.
  • a hole with a defined distance parallel to the main cutting edge of the insert opposite the surface is sufficient, and if necessary a cross hole with thread and grub screw to prevent it from falling out.
  • a rotation of the bolt from 0 ° to 90 ° about its axis causes an axial movement of the cutting plate of 0-0.1 mm over the eccentric surface. This is sufficient for fine adjustment of one or more inserts in a milling cutter.
  • 1 is a view of a bolt according to the invention
  • 2 shows an alternative embodiment of a bolt with an external thread
  • FIG. 4 shows a top view of the bolt according to FIG. 3,
  • FIG. 5 shows a carrier tool according to the invention with an inserted insert
  • FIGS. 5 and 6 shows a side view of the carrier tool according to FIGS. 5 and
  • FIG. 8 is a top view of the carrier tool according to FIG. 5.
  • the bolt 10 can consist of hardened steel, hard metal, industrial ceramics or another hard and wear-resistant material.
  • the version can consist of slot 13, hexagon socket, Torx or another screw drive and can be introduced on one or both sides.
  • An external thread 14 or a threaded bore is also conceivable on one side.
  • Another feature is the constriction 15, which is to serve to lock the bolt in its holder and to reduce the contact surface (2-line contact).
  • FIG. 3 shows the bolt 10 in its length and FIG. 4 in the top view of FIG. 3.
  • the eccentrically attached surface 12 is shown as a special characteristic, the eccentric center to the center of the bolt by an amount 16 of 0.1 to 0.5 mm is offset. This later defines the adjustment range, which appears when the bolt is turned around its axis. Dimension 17 is therefore the smallest dimension and dimension 18 the largest dimension of the adjustment range.
  • the radius dimensions (19 and 20) each show the pin radius and the eccentric radius.
  • the zero position is identified by reference numeral 32. This is a marker to facilitate the setting.
  • the center of the eccentric is identified by reference number 30 and the center of the bolt by reference number 31.
  • FIG. 5 shows the fine adjustment or the bolt 10 in a carrier tool 21 with a cutting insert 11.
  • FIG. 6 shows an insight into the insert seat of the carrier tool, where the position of the fine adjustment can be clearly seen.
  • the opening 22 of the bolt bore through the insert seat wall 23, which enables the adjustment of the cutting insert by the bolt, is to be mentioned as a special feature.
  • Another feature is the threaded pin 24, which is intended to secure the bolt from falling out.
  • FIG. 7 shows the side view of the cutting insert and the fine adjustment or the bolt 10.
  • the zero position is shown.
  • the small eccentric dimension is congruent with or behind the panel seat wall.
  • a 90 ° rotation of the bolt 10 counter-clockwise about its axis would move the cutting insert to the left by the maximum adjustment range.
  • Another 90 ° turn clockwise and manual adjustment of the insert manually moves it back to the insert seat wall.
  • Fig. 8 shows the top view of the insert. The position of the threaded pin 24, which serves to lock the fine adjustment bolt 10, can be clearly seen.

Abstract

L'invention concerne un outil support destiné aux plaquettes de coupe (11) d'un outil de coupe par enlèvement de copeaux, la plaquette de coupe (11) étant en contact avec au moins une paroi (23) de l'outil support (21), cette paroi faisant office de siège de plaquette. L'invention concerne également des éléments de réglage fin destinés à l'ajustement de la position des plaquettes de coupe (11). Pour améliorer la précision de réglage et faciliter la manipulation, l'élément de réglage fin est constitué d'un boulon rotatif (10) doté d'une surface excentrique (12), le boulon (10) étant placé dans la paroi siège de plaquette (23). Lorsque le boulon (10) est en position neutre, la surface excentrique (2) affleure la paroi siège de plaquette (23) ou est placé dedans et lorsque le boulon (10) est en mode d'utilisation, la surface excentrique (12) fait saillie de la paroi siège de plaquette (23).
