Abstract

The invention relates to the field of metal cutting and can be used in end mills. when machining flat surfaces. The aim of the invention is to simplify the design by combining axial and radial adjustments of rezts plates. The face milling cutter consists of a body 1, in the slots 2 of which the cutting plates 3 are placed, which are adjustable in the axial and radial directions by means of an adjusting wedge 4 and the differential screw 5, and the supporting element 7 placed in the holder 8. For adjusting the cutting plates in the radial The clamping wedge 12 is fastened in the direction and by means of moving the wedge 4 through the support element 7, a cutting plate is installed. For adjustment in the axial direction, the clamping wedge 10 is loosened, the support element 7 is fixed with a screw 9 and the movement of the holder 8 is communicated with the cutting plate by the adjusting wedge 4. 3 Il.

The invention relates to the field of metal cutting and can be used in face mills when machining flat surfaces.

The aim of the invention is to simplify the design by combining axial and radial adjustments of the cutting inserts.

acting on its wedge surface, the support element 7 moves at an angle o / s, and the cutting plate 3 at an angle iX, relative to the holder 8, while the plate 3 moves from position 1 to position P. Vertex D of plate 3 in one turn of screw 5 moves by OD in RNA 1 shows the face direction and the OD value.

in} in FIG. 2 is a section A-A in FIG. 1; Wah FIG. 3 - adjustment scheme of the cutting plate.

Tortsova freza.ostoit from korpu axial direction. After the plate 3 is mounted on the required size in the radial direction, the screw 9 secures the support element 7 with respect to 1, in which j holder 8 is made parallel to j. After that, the plate 3 is adjusted in the axial direction, for this purpose the clamping wedge 10 is loosened The screw 5 moves the adjusting wedge 4 perpendicular to the axis of rotation of the milling cutter, which, by acting on its wedge surface on the support element 7 fixed relative to the holder 8, informs it to move along the groove 2.

its axes are grooves 2 designed to place cutting plates 3 in them at an angle u (i to the mill axis in the radial plane, each plunger 3 equipped with an adjusting device to move it in the axial JH radial directions. The device to adjust the plate 3 contains an adjusting wedge 4, made with a wedge surface at an angle c / 2 to the cutter axis, installed with the possibility of radial movement in groove 2 using a differential screw 5 having two thread sections with different pitch, and 30 contact with an annular support element 6 and a support element 7 placed 1M in the holder 8 for axial movement at an angle of (5 to the axis of the cutter and in contact with the gland plate 3. For fixing the support element 7 relative to the holder 8, there is a locking screw 9, for fixing the holder 8 with respect to the cutter body 1 there is a clamping wedge 10 with a screw 11, and for fixing the cutting plate 3 relative to the body 1 and the holder 8, a clamping wedge 12c is provided with a screw 13.

The adjustment of the plates 3 is carried out in two steps as follows.

Initially, the plate 3 is adjusted in the radial direction, for which the clamping wedge 12 is loosened, turning the screw 5 moves the adjusting wedge 4 relative to the supporting element 6 perpendicular to the axis of rotation of the milling cutter, which by means of

During one turn of the screw, the top D of the cutting plate 3 moves by the amount D of the axial direction and occupies position III. After installing the plate 3 to the required size in the axial direction of it and the holder 8 is wedged. 10 and 12 relative to the body 1 of the cutter.

Claims (1)
