Abstract

Изобретение относитс к области станкостроени , в частности к резцедержател м, и может быть использовано в станках токарной группы. Целью изобретени вл етс повышение удобства обслуживани резцедержател за счет регулируемого поворота его корпуса. Резцедержатель содержит основание с закрепленной на нем осью 2, установленную на оси фиксированно от поворота втулку с кронштейном 5 в форме вилки 6, котора размещена в радиальном пазу 8 корпуса 7, установленного с возможностью поворота йа втулке. В резьбовых отверсти х вилки установлен микрометрический винт 9 с лимбом 10. Концы 11 винта контактируют со стенками паза 8. При отпущенной гайке 13 корпус 7 отжимаетс от основани и его угловое положение регулируетс вращением лимба 10 с контролем положени по указателю 14. Поворот корпуса осуществл етс за счет взаимодействи концов 11 винта с пазом при перемещении винта в ту или другую сторону в резьбовых отверсти х вилки 6. 2 ил.The invention relates to the field of machine tools, in particular to tool holders, and can be used in lathes of the turning group. The aim of the invention is to improve the serviceability of the tool holder due to the adjustable rotation of its body. The tool holder contains a base with an axis 2 fixed on it, fixed on the axis fixedly from rotation a sleeve with a bracket 5 in the form of a fork 6, which is placed in the radial groove 8 of the housing 7 mounted with the possibility of rotation of the sleeve. A micrometer screw 9 with a limb 10 is installed in the threaded holes of the plug. The screw ends 11 are in contact with the walls of the groove 8. When the nut 13 is released, the body 7 is pressed from the base and its angular position is adjusted by rotating the dial 10 with position control according to the pointer 14. The body rotates due to the interaction of the ends of the 11 screws with a groove when the screw is moved to one or the other side in the threaded holes of the plug 6. 2 Il.

Claims

Claim

15 A tool holder comprising a base with an axis fixed to the Yem, mounted on the base rotatably relative to the axis, a housing with grooves for cutters, a nut mounted on the 2Q axis for clamping the housing to the base, and housing positioning elements in the required angular position, characterized in that, in order to improve the convenience of maintenance, the positioning elements of the housing are made 25 in the form of a sleeve with a bracket in the form of a fork, placed in a radial groove made in the “housing”, and micrometric th screw with a limb in the middle part installed in threaded holes made in the fork with the possibility of simultaneous interaction of the supporting surfaces of its ends with the walls of the radial groove in the housing, while the sleeve is mounted inside the housing on the axis with the possibility of axial movement and is fixed from rotation and spring-loaded relative to the base to

35 nut.
