Изобретение относитс к обработке металлов резанием.The invention relates to metal cutting.

Известно устройство дл расточки, содержащее неподвижный корпус, суппорт с резцедержателем, установленный с воз-, можностью перемещени и кинематически св занный с приводом подачи, включающим звездочку, и механизм управлени (IJ.A boring device is known which comprises a fixed housing, a support with a tool holder, mounted with possibility of movement and kinematically connected with a feed drive including a sprocket, and a control mechanism (IJ.

Недостатком известного устройства вл етс невозможность растачивани канавок и подрезки.торцов.A disadvantage of the known device is the impossibility of boring grooves and trimming the cutters.

Цель изобретени - расширение технологических возможностей.The purpose of the invention is the expansion of technological capabilities.

Указанна цель достигаетс тем, что механизм управлени выполнен в виде вала, с установленными на нем шестерн ми, и управл ющих элементов, на боковых поверх- ност х которых выполнены -рейки, взаимодействующие с упом нутыми шестерн ми, причем управл ющие элементы установлены с возможностью перемещени и поперечного взаимодействи со. звездочкой, а вал размеш ,ен в неподвижиом корпусе с возможностью поворота.This goal is achieved by the fact that the control mechanism is made in the form of a shaft, with gears mounted on it, and control elements, on the side surfaces of which there are ribs interacting with said gears, and the control elements are installed with displacement and transverse interaction with. an asterisk, and the shaft is placed, en in a fixed body with the possibility of rotation.

на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1.in fig. one; in fig. 3 shows a section BB in FIG. one.

Головка содержит оправку 1, при помо .щи которой она крепитс в конусе шпиндел станка, вращающийс корпус 2, в котором на подшипниках установлен вал 3 со звездочкой 4, св занный зубчатой передачей 5 и 6 с ходовым винтом 7, перемещающим вдоль направл ющих скольжени корпуса 2 суппорт 8 с резцедержателем 9 и резцом 10.The head contains a mandrel 1, with the help of which it is mounted in the machine spindle cone, rotating the body 2, in which the bearings have a shaft 3 with an asterisk 4 connected by a gear 5 and 6 with the lead screw 7 moving along the body guides 2 support 8 with tool holder 9 and cutter 10.

JQ Неподвижный корпус 11 взаимодействует с вращающимс корпусом 2 при помощи бронзового кольца 12 и стопоритс от проворота специальным стержнем, укрепленным на неподвижном узле станка (не показан ) и вставленным в отверстие 13, илиJQ The stationary body 11 communicates with the rotating body 2 by means of a bronze ring 12 and is locked from turning by a special rod fixed on the stationary assembly of the machine (not shown) and inserted into the hole 13, or

15 вручную.15 by hand.

На неподвижном корпусе 11 размещен механизм управлени вращением звездочки 4 вокруг собственной оси, содержащий два подвижных в радиальном направлении управл ющих элемента 14 и 15, на боковыхOn the stationary housing 11 a spindle 4 rotation control mechanism is placed around its own axis, containing two radially movable control elements 14 and 15, on the side

Claims

24 of which surfaces are lath interacting with gears 16 and 17 ,. mounted on one shaft 18, which is rotated by the handle 19. The handle has three positions, the middle one, in which the control elements do not interact with the side surfaces of the stars; daughter, the left extreme, in which the control element 15 interacts with an asterisk, and the right extreme one, in which the control element 14 interacts with the asterisk. The distance from the axes of the control elements 14 and 15 to the axis of the asterisk 4, influencing the angle of rotation the sprocket when interacting with the control element can be adjusted, for which grooves 20 and 21 are provided. Bolts 22 and 23 serve to fix the machines 24 through the gaskets 25 in a certain position. The head works as follows. Case 2 receives rotation from the machine spindle. Housing And does not rotate. Handle 19 is in the middle position. The tool holder 9 is inserted inside the hole by the machine at the desired position. Further, the handle 19 is rotated in one of the extreme positions, for example to the left. In this case, the control element 14 moves the gear of the belt b in the direction of the sprocket 4 and at each meeting of the sprocket with the control element one of its teeth interacts with its side surface with the cylindrical end of the control element and turns the sprocket at a small angle. This causes the caliper 8 and the tool holder 9 to periodically move in the radial direction. Cutter 10 cuts into metal; As the required depth is reached, which is controlled by a Vernier, a ruler, a hard stop, etc. (not shown), the handle 19 moves to the middle position. The spindle, along with the head, receives axial feed and bores the hole to the required depth. Upon reaching the required depth, the handle 19 moves to the next extreme position, in which the second control element 15 interacts with the sprocket, which ensures that the sprocket turns periodically in the other direction and, therefore, reverses the working transverse feed of the tool. After the end trimming is completed, the head is retracted by the machine spindle to its original position. Such a device structure for boring and trimming is characterized by simplicity and reliability of the design. It can be used on turning, boring, milling, drilling and other machines for the manufacture of internal cavities, recesses, trimming of end surfaces, etc. The invention A device for boring and cutting, containing a fixed body, a support with a tool holder that is mounted to move and kinematically associated with a feed drive, including an asterisk, and a control mechanism, characterized in that, in order to expand the technological possibilities, the control mechanism is made in the form of a shaft, gears mounted on it, and control elements, on the side surfaces of which are laths interacting with said gears, the control elements being installed with the possibility of displacement and transverse interaction with an asterisk, and the shaft is scattered in the fixed case .
