RU2283731C1 - Disk milling cutter - Google Patents

Abstract

FIELD: metal working.

SUBSTANCE: milling cutter comprises housing defined by sides and peripheral surface whose riffle grooves parallel to axis of the milling cutter receive cells secured by means of the differential screws and wedges and are provided with sockets for receiving cutting plates. Each groove is adjacent to the opening that is parallel to the axis of the milling cutter and receive the means for axial adjusting of the position of the cell provided with the cutting plate. The means for axial adjusting is made of detachable device that has rod whose one end is provided with the transverse projection for the cooperation with the bottom and sides and grooves in the sides of the housing and other end is provided with the thread for connection with the bushing whose face points to the transverse projection of the rod and interacts with the cell in the course of its axial adjustment.

EFFECT: enhanced convenience of axial adjustment.

Description

The invention relates to the field of metal cutting, precast cutting tool.

Known disk milling cutter, comprising a housing bounded by lateral surfaces and a peripheral surface, in the grooves of which on the corrugations parallel to the axis of the milling cutter, mounted with differential screws and wedges cassettes with slots for installing mechanically fixed cutting plates, parallel to each groove adjacent to the axis milling cutters a hole for placement of the tool for axial adjustment of the position of the cartridge with a cutting plate fixed on it, made in the form of adjusting screws (see WO 2004/033137, 23 C 5 / 20, 2004).

A disadvantage of the known disk mill is the inconvenience of axial adjustment of the position of the tops of the cutting inserts by moving the cartridges if they are replaced on the machine, since the key holes in the adjusting screws are clogged with chips. The objective of the invention is to improve the convenience of adjusting the position of the vertices of the cutting inserts on the machine. The problem is solved in that a disk mill containing a housing bounded by lateral surfaces and a peripheral surface, in the grooves of which on corrugations parallel to the axis of the mill, are mounted fixed with differential screws and wedges of the cartridge with slots for installing mechanically fixed cutting plates, while each groove adjoins a parallel hole to the cutter axis to accommodate means for axially adjusting the position of the cartridge with a cutting plate fixed to it, and said axial means The adjustment is made in the form of a removable device containing a rod, at one end of which there is a transverse protrusion for interacting with the bottom and side surfaces of the grooves made on the side surfaces of the housing, and at the other end is a thread for connection with a sleeve whose end facing the transverse the protrusion of the rod, designed to interact with the cartridge in the process of its axial adjustment.

The proposed disk mill is shown in figures 1-3, where

figure 1 shows a front view of the groove of the disk cutter body with a cassette with a cutting plate fixed in it;

figure 2 shows a view of figure 1;

figure 3 separately shows the axial adjustment device on an enlarged scale.

The disk mill contains a housing limited by the lateral surfaces 1 and 2 and the peripheral surface 3. In the grooves of the housing (one of which is shown in FIGS. 1 and 2) on the corrugations 4 parallel to the axis of the mill, there are cassettes 5 fixed with differential screws 6 and wedges 7. Each cartridge has a slot for mounting the cutting insert 8 and securing it, for example, with a screw through a central hole (not shown in FIGS. 1 and 2). An opening 9 is adjacent to each groove parallel to the cutter axis to accommodate the tool for axial adjustment of the position of the cartridge 5 with the cutting plate fixed to it 8. The tool for axial adjustment is made in the form of a removable device 10 containing a rod 11, at one end of which there is a transverse protrusion 12 for interacting with bottom and sides of the groove 13, made on the side surfaces 1 and 2 of the mill body. At the other end of the rod 12, a thread 14 is made for connection with the sleeve 15. The end face 16 of the sleeve 15 is designed to interact with the cartridge 5 in the process of axial adjustment. Between the rod 11 and the sleeve 15 is placed a spring 17.

If it is necessary to carry out the adjustment of the axial position of the vertices of the cutting inserts 8 facing one of the side surfaces (for example, 2, as in FIG. 1), the differential screw 6 is slightly loosened in the corresponding grooves of the cutter body, and a removable device is installed in the hole 9 10. In this case, the transverse protrusion 12 of the rod 11 enters the groove 13 on the side surface of the housing. Then, by rotating the sleeve 15 through a measuring device (not shown), the necessary position of the vertices of the cutting plates 8 is established and the differential screws 6 are tightened.

Claims (1)

A disk mill containing a housing bounded by side surfaces and a peripheral surface, in the grooves of which on corrugations parallel to the axis of the mill, are mounted cassettes with sockets for installing mechanically fixed cutting inserts fixed with differential screws and wedges, and parallel to the axis of the mill is adjacent to each groove an opening for accommodating the axial adjustment means of the cartridge with a cutting plate fixed on it, characterized in that said axial adjustment means o in the form of a removable device containing a rod, on one end of which a transverse protrusion is made for interacting with the bottom and side surfaces of the grooves made on the side surfaces of the housing, and on the other end is a thread for connecting to a sleeve whose end face facing the transverse protrusion of the rod , designed to interact with the cartridge in the process of its axial adjustment.
