Abstract

The invention relates to the machining of materials. (Alaid cutting, in particular, to metal cutting. The aim of the invention is to improve the machining accuracy by increasing the rigidity of the holder and tool holder in the attachment. The tool holder 2 has an external thread under the adjusting sleeve in the opening 1 of the insert 1. 3. The flats on the shank 6 of the tool holder 2 enter the transverse groove on the intermediate sleeve 4, on which the bald faces are also made to interact with the side walls 7 of the transverse groove on the body 1. Side walls 7 p The opening is located at an angle to the axis of the insert, not exceeding the angle of self-locking. In the hole at the end of sleeve 4 there is a compression spring 8, limited by the end face 9 of the tightening screw 10. When installing the insert in the hole of the mandrel, tighten the screw 10. At the same time, the side surfaces 7 wedge the petals of the housing 1 formed by the transverse groove on the mandrel, providing a rigid fixation of the position of the housing i on the mandrel.

Claims (2)

Invention Formula interacts with a conical section in the opening of the housing 1. The latter also contains an intermediate insert 4 with a transverse groove, the side walls 5 of which have a Q vick tool holder, which, in turn, interact with the flats on the shank 6, in order to improve the accuracy of the tool holder 2. sleeve 4 is made of flats for interaction with the lateral sides 7 of the transverse groove on the housing 1. Moreover, these lateral sides are angled to the axis of the insert, not the front part for engagement with the cutting edge voltage (not bo-holder and head for vzanmodeylee 5 °). In the hole on the side of the end of the intermediate sleeve 4, a spring 8 is installed, which is limited by a collar 9 of the tightening screw 10, the threaded part of which is housed in the tool holder 2. A replaceable cutting plate 11 is fixed on the head of the tool holder 2. to interact with the flats on the tails by increasing the rigidity of the tool holder attachment, the tool insert is provided with a tightening screw-thread, which is spring-loaded relative to the intermediate sleeve. The ends of the intermediate sleeve, while on the last, flats are made to interact with the transverse groove made on the housing, the side walls of the said groove being located to the axis of the insert at an angle less than the self-locking angle. (pui.2 Invention Formula Vick toolholder, characterized in that, in order to increase the accuracy of the machining part to interact with the tool holder and the head for taking up the modular interaction with the flats on the toolholder shank, in order to improve the accuracy of the machining part for engagement with the cutter holder and the head for the breechbag by increasing the rigidity of the tool holder attachment, the tool insert is provided with a pivot screw relative to the intermediate sleeve The ends of the intermediate sleeve, while on the last, flats are made to interact with the transverse groove made on the housing, the side walls of the said groove being located to the axis of the insert at an angle less than the self-locking angle. / 1 A 7 (ri gz
