Description

Изобретение относитс к станкостроению , а именно к устройствам дл обработки деталей из труднообрабатываемых металлов.The invention relates to a machine tool industry, in particular to devices for machining parts from hard-to-machine metals.

Известен многошпиндельный токарный- станок, содержащий переднюю баб- ку, во вращающемс шпиндельном блоке которой смонтированы шпиндели, кинематически св занные с этим блоком, и суппорт, кинематически св занный со шпиндельным блоком. 1.A multi-spindle turning lathe is known, which contains a forehead, in a rotating spindle block of which spindles are mounted, which are kinematically connected with this block, and a support kinematically connected with the spindle block. one.

Однако при точении на этом станке , зона контакта резца, неподвижного в плоскости вращени заготовок, с каждой заготовкой огранич&на углом поворота шпиндел в пределах станка.However, when turning on this machine, the contact area of the tool stationary in the plane of rotation of the workpieces, with each workpiece, is limited & on the angle of rotation of the spindle within the machine.

Цель изобретени - повышение производительности .The purpose of the invention is to increase productivity.

Цель достигаетс тем, что станок снабжен установленным на суппорте инструментальным шпинделем, ось вращени которого не совпадает с ос ми вращени шпиндельного блока и шпинделей , суммирующим механизмом, выход которого кинематически св зан с инструментальным шпинделем, органом настройки, посредством которого шпиндельный блок св зан с одним из входов суммирующего механизма, а другой его вход св зан с введенным в станок меThe goal is achieved by the fact that the machine is equipped with a tool spindle mounted on a support, the rotation axis of which does not coincide with the axis of rotation of the spindle unit and spindles, a summing mechanism, the output of which is kinematically connected with the tool spindle, a setting element, through which the spindle unit is connected from the inputs of the summing mechanism, and its other input is associated with the input into the machine

ханизмом синхронизации вращени инструментального шпиндел и шпиндельного блока.synchronization of rotation of the tool spindle and the spindle unit.

с На чертеже изображена структурна сх-ема станка.c The drawing shows the structural scheme of the machine.

Электродвигатель 1 при помощи кинематической цепи, содержащей кинематическую передачу 2, орган 3 4п йастройки (коробка скоростей, сменные шкивы, гитара,сменных зубчатых колес), кинематическую передачу 4, Центральный вал 5, зубчатые передачи 6, св зан со шпиндел ми 7, которые смонтированы в шпиндельном блоке 8 (симметрично вокруг оси 9 его вращени в корпусе передней бабки 10.The electric motor 1 by means of a kinematic chain containing a kinematic transmission 2, an organ 3 4p adjustments (gear box, interchangeable pulleys, guitar, interchangeable gears), kinematic transmission 4, Central shaft 5, gears 6, is connected to spindles 7, which mounted in the spindle unit 8 (symmetrically around the axis 9 of its rotation in the body of the headstock 10.

Шпиндели 7 св заны кинематической цепью, содержащей зубчатые переДЬчи б, кинематическую передачу 4, орган 11 настройки (гитара сменных зубчатых колёс) , кинематические передачи 12 и 13, с шпиндельным блоком 8.The spindles 7 are connected by a kinematic chain containing gears b, kinematic gear 4, tuning organ 11 (guitar of interchangeable gears), kinematic gears 12 and 13, with spindle unit 8.

Claims

Spindle unit 8 is connected by a kinematic chain containing kinematic gears 12 and 13, tuning body 14 (guitar of interchangeable gears), kinematic gear 15, rack and pinion gear 16 with longitudinal caliper 17 carrying a transverse caliper 18. A transverse spindle 19 is mounted on the transverse caliper, the axis of rotation 20 of which does not coincide with the axis of the rotation of the 9 spindle block 8 and 21 of the spindles 7. The spindle of the spindle 19 sets the tool rest 22 of the tool spindle 19 by means of a kinematic transmission 23 and a section of the kinematic chain 24 connected to the output 25 of the summing mechanism 26. Inlet 27 of the summing mechanism 26 is kinematically connected through the tuning element 28 (guitar of interchangeable gears), kinematic gears 12 and 13 with the spindle unit 8, Input 29 of the summing mechanism 26 is kinematically connected with the synchronization mechanism 30 the circular frequencies of rotation of the spindle unit 8 and the instrumental spindle 19, made for example in the form of a handle 31, whose rotation through a kinematic connection 32 is communicated to the input 29 of the summing mechanism 26. The setting elements 3.11 and 28 are used for setting the circular parts of the rotation, respectively, of the spindles 7 of the spindle unit 8 and the tool spindle 19. The adjustment tool 14 is used to set the longitudinal feed. The machine works as follows. When electric motor 1 is turned on, spindles 7 follow a kinematic chain; kinematic transmission 2, tuning body 3 ,. kinematic transmission 4 central shaft 5, gears 6 receive rotation. At the same time, along the kinematic chain, gears, b, kinematic gear 4, tuning body 11, kinematic gears 12 and 13, the spindle unit 8 receives rotation, and, according to kinematic chains, kinematic gears 12 and 13, tuning body 28, input 27 of summing mechanism 26, output 25 of this mechanism, the kinematic transmission 23 receives the rotation of the tool spindle 19. Then, rotating the handle 31 of the rotation synchronization mechanism, the input 29 of the summing mechanism 26, the output 25 of this mechanism and the kinematic transmission 23 are reported rotational movement of the tool spindle 19. This movement continues until the initial point of contact of the rotating tool does not coincide with the starting point of the cutting zone determined by the portable rotation of the spindle unit B. After this, the longitudinal feed of the support 17 : kinematic gears 13 and 12, tuning unit 14, kinematic gear 15, rack and pinion gear 16. As a result of the message, the movements of cooked chips with separate elements. The use of the proposed machine in comparison with the known provides improved processing performance. At the same time, reliable chip breaking is ensured and the safety of maintenance of the machine is increased.
