Description

The invention relates to machine tools, in particular to the holders for non-rotating tools, and can be used when turning bar material. The aim of the invention is to improve the tuning accuracy of the cutting elements in the radial direction due to the elimination of gaps in the setting mechanism * The cutting head contains evenly placed circumferentially cutting elements 1, which are fixed to the sectors of the disc-shaped membrane 2 with radial non-through slots. The membrane 2 is fixed on the outer diameter in the casing 3. In the threaded hole of the casing 3 is placed the sleeve 4, acting on the disk 5. The latter is installed in the casing 3 with the possibility of axial movement. The exclusion of the axial rotation of the disk is provided with the help of the key 6. In the screw holes of the disk 5 there are placed adjustment screws 7 for setting the cutting elements. Screws 7 affect the sectors of the membrane 2. 2 Il.

The invention relates to a machine tool industry, in particular to holders for non-rotating tools, and can be used for turning a bar material.

The purpose of the invention is to improve the accuracy of setting the cutting elements in the radial direction by eliminating gaps in the mechanism of tuning.

FIG. 1 shows a cutting head, a longitudinal section, a general view; in fig. 2 is a view A of FIG. one.

The cutting head contains uniform-15 but placed around the circumference of the cutting elements 1, which are fixed on the sectors of the disc-shaped membrane 2 with radial non-through grooves. The membrane 2 is fixed on the outer diameter of 20 in the holder 3. In the threaded hole of the holder 3 is placed a sleeve 4, acting on the disk 5. The latter is installed in the cylindrical hole of the holder 3 with the possibility of axial ^ 5 movement. The exception of the circumferential rotation of the disk is provided by the key 6. In the screw holes of the disk 5 there are placed adjustment screws 7 for adjusting the cutting elements. Win-30

Claims (1)

Claim A cutting head comprising a housing with cutting elements evenly disposed on it circumferentially and a mechanism for adjusting them in the radial direction, characterized in that, in order to improve the tuning accuracy of the cutting elements, the housing is designed as a yoke with cylindrical axial and threaded holes, and made in the form of a disc-shaped membrane fixed on the outer diameter in the cage with radial non-through grooves forming sectors on it, on which cutting elements are fixed, mounted cylindrical bore cage for axial displacement and rotation of the disc is fixedly mounted in the threaded hole of the cage to cooperate with the drive sleeve and placed in the disk for engagement with the sectors membrane adjusting screws.
