Definitions

  • a cutting tool is known from US Pat. No. 703,755, which has a displaceable insert in the recess of the holder. Here, too, it is provided to use a reground cutting insert and to move it into the original position of the unground grinding insert by means of a displaceable system.
  • a drilling tool is known from US Pat. No. 4,066,376 which has a receptacle for the cutting insert which is delimited by a circular arc. This holder can be fixed in certain predetermined positions by inserting pins.
  • the object of the present invention is therefore to create a possibility of compensating for these tolerances by means of adjusting devices and thus of creating the possibility of complying with the required high dimensional accuracies without complex post-processing.
  • the adjustment insert is in a recess in the
  • Holder arranged tool head inserted, the tool head and the adjustment insert are via one
  • Locking screw connected to each other, adjusting means for adjusting the adjustment insert are arranged in the side cheeks of the recess.
  • the adjusting means consist of eccentrics or screws provided with fine threads.
  • the configuration with an eccentric is particularly preferred, since this configuration makes it possible to adjust the cutting insert from above, that is to say from a surface which is generally easily accessible. Machining space is also generally available from below, so that the locking screw, which extends through the tool head into the adjustment insert, can be tightened after the fine adjustment, so that the position of the cutting insert once set is fixed.
  • the adjustment insert is guided in the recess, the guide advantageously consisting of a groove on the bottom of the recess and an engaging spring connected to the adjustment insert, which advantageously extends at an angle to the right side cheek of the recess.
  • the guide advantageously consisting of a groove on the bottom of the recess and an engaging spring connected to the adjustment insert, which advantageously extends at an angle to the right side cheek of the recess.
  • a particularly advantageous embodiment of the invention provides that the adjustment insert consists of a sled chair which carries a sled which is guided in it and the adjustment insert is guided in the recess by a tongue or groove.
  • This construction results in a cross guide, i. H. that the adjustment of the cutting plate is possible both in the X and Y planes, with the slide being displaced by an eccentric in one case and the entire adjustment insert in the other case.

  • the cutting head (32) which is manufactured in different embodiments for receiving differently designed cutting plates (13) and different plate clamping systems, is connected to the clamping unit (31) via a hydraulically actuated coupling (33) which engages in the coupling bore (34) . It has a recess (2) in which an adjustment insert (1) is arranged. The locking screw (5) engages in the adjusting insert (1), which passes through the cutting head (32) from below and can be actuated from here.
  • the adjustment insert (1) is shown in FIGS. 1 to 3 as a one-piece angle piece with a flat bottom, in FIGS. 4 to 6 as a one-piece angle piece which is provided on its bottom with a spring (27) which is inserted into the groove ( 26) of the recess (2) engages.
  • an adjusting device which is designed as an eccentric (8) according to FIGS. 1 to 6, the adjustment insert (1) is displaced, which according to FIG. 4 to 6 along the groove (26).
  • the adjustment insert (1 ') is made in two parts and consists of the sled chair (35), on the bottom of which the spring (27) is formed, which engages in the groove (26) of the recess (2), the slide (28), which is arranged at right angles on the slide chair (35), engages with its slide spring (30) in the slide groove (29) arranged in the slide chair.
  • the movement of the slide (28) is obtained by actuating the left eccentric bearing (4), also by inserting a hexagon key (not shown) into the hexagon socket (22) and turning the key.
  • the bearing bore (21) or (21 ') is arranged both in the right eccentric bearing (3) and in the left eccentric bearing (4) so that the eccentric (8) in the pivoted-in state does not have the right side cheek (6) or the the left side cheek (7) protrudes, the slide (28) or the sled chair (35) therefore lies against the side cheeks (6) or (7).
  • the hexagon socket (22) is accessible from above, ie the cylinder extension (20 ') is mounted in the cover plate (19).
  • Fig. 9 shows the Possibility of making the adjustment also from below, ie the hexagon socket (22) can be reached via an additional hole in the cutting head (32).
  • the adjusting insert (1) and the slide (28) each have a threaded hole (36) into which the locking screw (5) engages. It passes through the bore (15) in the cutting head (32) with the formation of a larger play in order to enable the adjustment insert (1) to be adjusted. Since the adjustment can be carried out both in the X and in the Y axis, the bore (15) is not designed as an elongated hole, but only has an enlarged diameter. It is covered by the washer (17), which is arranged in front of the screw head (37) in the depression (16).
  • the clamping claw (11), as shown in all figures, is connected to the cutting head (32) by the clamping screw (10).
  • Your cam (18) is supported in the rear part of the cutting head (32), this support possibly being provided on the slope (45), so that when the clamping screw (10) is tightened by screwing it into the threaded bore (12) the clamping claw (11) exerts a force which pulls the clamping claw (11) backwards, as a result of which the cutting insert (13) in the adjusting insert (1) or slide (28) and slide chair (35) on the contact surfaces (1b) and ( 1c) is pulled and pressed onto the insert base (1a).
  • the cutting plate (13) rests in the upper region on the right contact surface (1b) and the left contact surface (1c). In the lower area this results in the free space (40) - 40 '' on the right and 40 'on the left -.
  • the clamping claw (11) is provided with wings (14) which engage in recesses (42).
  • the wings (14) form in cooperation with the recesses (42) an anti-rotation, but, as can be seen in particular from FIGS. 3, 6 and 9, there is play between the wings (14) and the recess (42) allow movement of the clamping claw (11).
  • clamping claws (11) are shown, which are not provided with wings (14).
  • a guide pin (44) which was driven into the cutting head (32), serves as an anti-rotation device.
  • This guide pin (44) is encompassed by the guide (43) designed as a rectangular recess in the rear region of the clamping claw (11).
  • the arrangement is selected such that there is a greater clearance between the guide pin (44) and the inner boundary surface of the guide (43) in the direction of the clamping screw (10) in order to enable movement of the clamping claw (11).
  • Fig. 10 shows a perspective view of a cutting head (32), which also contains a sled chair (35) with a slide (28), but sled chair (35) and slide (28) are adjusted with fine-thread screws (9). These fine-thread screws (9) are as
  • FIGS. 11 and 12 are designed as an exploded diagram or as a side view in section.
  • FIG. 13 shows an exploded diagram and FIG. 14 shows a top view of an exemplary embodiment in which the adjusting insert (1) engages with a diagonal spring (27 ') in the diagonal groove (26') arranged in the bottom (25) of the recess (2).
  • the adjustment insert (1) is only possible in one direction, namely in the running direction of the diagonal groove (26) or the diagonal spring (27).
  • the adjustment insert (1) therefore has a footprint (51) which is acted upon by the fine-thread screw (9 '') in the area of the pressure surface (50).
  • 15 to 19 are top views of different shapes of the cutting plate (13).
  • 15 shows a square insert, FIGS. 16 and 19 rhombic inserts and FIGS. 17 and 18 triangular inserts, in FIG. 17 the adjustment insert (1) is adjusted with a fine-thread screw (9).

Abstract

Un outil coupant pour l'usinage par enlèvement de copeaux dans des systèmes à changement d'outil se compose d'une tête de coupe (32) logée dans une unité de serrage (31) et renfermant dans un évidement (2) un insert d'ajustage (1, 28, 35) pour recevoir la plaque de coupe (13). Cette dernière et l'insert d'ajustage (1, 28, 35) sont reliés à la tête de coupe (32) respectivement par un mors de serrage (11) et par une vis de blocage (5). Dans les faces latérales (6, 7) de l'évidement (2) sont disposés des moyens (8, 9) de réglage de l'insert d'ajustage (1, 28, 35). Ce dernier peut être exécuté en deux parties et constitué d'un chariot (28) ainsi que d'un siège de chariot (35). Les moyens de réglage sont des excentriques (8) ou des vis à pas fin (9) s'étendant dans l'évidement (2).
