(54) ИНСТРУМЕНТАЛЬНАЯ БАБКА(54) TOOLS

1one

Изобретение Ьтноситс к конструктивным элементам и вспомогательным устройствам дл тоЬарных станков и может найти применение при обработке деталей с использованием тангенциальной подачи.The invention relates to structural elements and auxiliary devices for machine tools and may find application in machining parts using a tangential feed.

Известна: инструментальна бабка дл поступательного и вращательного движений HHCTpyMebfTa, содержаща корпус с установленной в нем с возможностью перемещени пинолью, смонтированной на пиноли на подшипниках шпинделей и привод поступательного перемещени пиноли, выполненный в виде гидроцилиндра 1.Known: the instrumental head for the translational and rotational movements of the HHCTpyMebfTa, comprising a housing with a quill mounted therein that can be mounted on quill bearings on spindle bearings and a quill displacement actuator made in the form of a hydraulic cylinder 1.

Целью изобретени вл етс упрощение конструкции за счет осуществлени поступательного и вращательного движени от одного мехг низма.The aim of the invention is to simplify the construction by carrying out translational and rotational movement from a single mechanism.

Дл этого гидроцилиндр соединен со шпинделем посредством многозаходной планетарной шарико-винтовой передачи, при этом на наружной поверхности гидроцилиндра выполнена винтова нарезка, а в шпинделе размещена планетарна гайка шарико-винтовой передачи.For this purpose, the hydraulic cylinder is connected to the spindle by means of a multiple-use planetary ball screw drive, while a screw is cut on the outer surface of the hydraulic cylinder, and a planetary nut of the screw screw gear is placed in the spindle.

На фиг1 i изображена ивтиндельна бабка, общий вид в разрезе; наOn figi i depicts an even grandmother, a general view in section; on

фиг. 2 - вид по стрелке А на фиг. 1. (начальное и конечное положение инс;грумента, определ емое углом, завис щим от параметров шарико-вин5 товой передачи); на фиг. 3 - разрез Б-Б на фиг. 1; на фиг. 4 - разрез В-В на фиг. 1.FIG. 2 is a view along arrow A in FIG. 1. (initial and final position of the ins; of the product, determined by the angle, depending on the parameters of the ball screw; 5); in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one.

В опораз4 скольжени корпуса 1 К установлена пиноль 2, в которой на подшипниках качени смонтирован инструментальный шпиндель 3 с зак- . репленной на нем разцовой головкой 4.In the slide of the body 1 K, a quill 2 is installed, in which the tool spindle 3 is mounted on rolling bearings with a set of zak. the raztsovy head replenished on it 4.

15 Инструментальный шпиндель 3 соединен с подвижным корпусом гидроци индра 5 посредством шарико-винтовой передали, состо щей из планетарной гайки 6 и винтовой нарезки 1 на кор20 пусе гидроцилиндра 5, шток 8 которого закреплен в крышке 9 корпуса 1 инструментальной бабки.15 The tool spindle 3 is connected to the movable case of hydroxide indra 5 by means of a ball screw passed, consisting of a planetary nut 6 and a screw thread 1 on the cylinder 20 of the hydraulic cylinder 5, the rod 8 of which is fixed in the cover 9 of the case 1 of the tool headstock.

От проворота во врем обработки инструментальный шпиндель 3 удер25 живаетс шпонкой 10. Величина продольного перемещени пиноли 2 настраиваетс регулируемым упором 11. The tool spindle 3 is retained by the key 10 against twisting during machining. The magnitude of the longitudinal movement of the quill 2 is adjusted by the adjustable stop 11.

Claims

H To prevent leakage, lubricate a special seal. 12. The operation of the device is enclosed in a follower. In the initial position, the pinola 2 is retracted from the part to the extreme right position. When the oil is supplied to the left cavity of the hydraulic cylinder 5, its core moves to the left. Together with the housing, the hydraulic cylinder 5 as a whole begins to displace the tool spindle 3 with a quill

2. Motion occurs without rotation, to which the pressure is applied to the moment of resistance and beyond the tension in the ball screw. When the system reaches the quill 2. spindle 3 with a cutting head stop. 11, the axial movement of the system is stopped. Due to the continued movement of the hydraulic cylinder 5, the spindle 3 rotates at an angle -. where b is the full stroke of the hydraulic cylinder; C - Penioli course; ) - the diameter of the pitch circle of the ball screw; . CJ is the elevation angle of the helix. For lathe mod. 1B 732 UROL, the rotation of the instrumental gear of cases 3 can be determined by the known parameters of the transmission and the stroke of the hydraulic cylinder. With D MMf L 80 mm, 30 mm, 01 45 360 ° 50 46 The application of the proposed tool head will ensure an even distribution of efforts over the contour of the machined part, making it possible to carry out turning with passing and counter feed. The invention The instrumental head of the translational and rotational movements of the instrument, comprising a housing with a quill mounted therein that can be moved, mounted on quill-like bearings on the spindle and a plnoli sliding actuator, made in the form of a hydraulic cylinder, so that the hydraulic cylinder is connected to the spindle by means of a multi-passage planetary ball screw drive, with the screw on the outer surface of the hydraulic cylinder zka, and in a spindle the planetary nut of a shariko - is placed. screw transmission.
