(5) ПОВОРОТНО-ДЕЛИТЕЛЬНЫЙ СТОЛ(5) TURNING TABLE

II

Изобретение относитс к поворотно делительным столам металлорежущих станков и может найти применение в многопозиционных станках с групповыми приводами рабочих органов.The invention relates to rotary-dividing tables for machine tools and can be used in multi-position machines with group drives of working bodies.

Известен поворотно-делительный стол, содержащий корпус с размещен .ной в нем планшайбой, св занной с редуктором поворота, через мальтий ский механизм, состо щий из жестко закрепленных на планшайбе планок, взаимодействующих с поводком, установленным на валу редуктора поворота, и фиксатор планшайбы, св занный через кулачок с редуктором поворота рТA rotary-dividing table is known, which includes a housing with a faceplate inside it, connected to the rotation gearbox, through a Maltese mechanism consisting of strips rigidly attached to the faceplate, interacting with a leash mounted on the rotational gear shaft, and a faceplate retainer, connected via cam with PT rotation gear

Однако этот стол сложен и имеет недостаточную надежность конструкции .However, this table is complex and has insufficient reliability of the design.

Кроме того поводок - ведущее звено мальтийского механизма - жестко соединен с валом черв чного колеса редуктора поворота, что вызывает необходимость остановки редуктора после каждого цикла поворота стола.In addition, the leash - the leading link of the Maltese mechanism - is rigidly connected to the shaft of the worm gear of the rotation gearbox, which makes it necessary to stop the gearbox after each cycle of table rotation.

Цель изобретени - упрощение конструкции и повышение ее надежности.The purpose of the invention is to simplify the design and increase its reliability.

Поставленна цель достигаетс тем, что стол снабжен двуплечим рычагом, установленным в корпусе с возможностью взаимодействи одним плечом с фиксатором, а другим - с поводком мальтийского механизма, причем упом нутый поводок установлен с возможностью возвратно-поступательного пе10 ремещени вдоль оси вала.The goal is achieved by the fact that the table is equipped with a two-arm lever mounted in the housing with the ability to interact with one arm with a lock and the other with a leash of the Maltese mechanism, and the aforementioned leash is mounted with the possibility of reciprocating movement along the shaft axis.

На чертеже представлен поворотноделительный стол, общий вид.The drawing shows a rotary table, a general view.

Поворотно-делительный стол состоит из корпуса -1 , в котором на оси 2 Rotary-dividing table consists of body -1, in which on axis 2

15 установлена планшайба 3 с планками k, образующими мальтийский крест, и втулками 5. В корпусе 1 размещена консольна шейка вала 6 черв чного колеса 7, соединенного с черв ком 8. 15, a faceplate 3 with strips k, forming a Maltese cross, and bushings 5 is installed. In case 1, a cantilever neck of a 6 worm gear wheel 7 connected to a worm 8 is placed.

Claims

20 On the cantilever neck of the shaft 6 is mounted with the possibility of axial movement of the disk 9 with a leash 10 Maltese mechanism. The disk 9 is connected by the bread crumbs 11 and the lever 12 with a spring-loaded latch 13 A gear 1 is mounted on the shaft 6 of the worm gear, which is an interchangeable pair with the gear 15 mounted on the shaft 16 mounted in the drive housing 17. A gear 18 is also mounted on the shaft 16, coupled with a gear wheel 19j on which a cam 20 is attached, which interacts with a pusher 21 mounted on a retainer 13 - Cherv k 8 is connected to an electric motor 22. The operation of the table 1 is asphdit as follows. In the initial position, the disc 9 with the driver 10 is lowered, the retainer 13 is inserted into the hole in the sleeve 5. the shaft 16, the gear 18 and the gear wheel 19 - the cam 20. When rotating, the cam 20, acting on the pusher 21, pulls the retainer out of the hole in the bushing 5, and through the crackers 11 and the lever 12, the disk 9 with the leash 10 rises to the upper position (lifting on the idle section of the tori movement path of the leash 10). Next, the lead 10 engages with the platens C and produces rotation of the faceplate 3 at a given angle. At the end of the turn, the driver 10 re-enters the idle section, at which point cam 20 releases clamp 13, the faceplate 3 is fixed. The proposed rotary-divider table design with an integrated electromechanical drive allows the introduction of a Maltese drive link (axially) moving in the axial direction. mechanism and attachment to the rotation gear 91 74 second stage, with a cam mounted on the driven gear wheel of this stage and interacting with the pusher fixed on e, considerably simplify the design, to ensure high reliability. The table of the proposed design is used in prototypes of multi-position drilling semiautomatic devices for drilling and countersinking of holes with a diameter of 4 mm. The performance of the proposed semi-automatic 3 times higher known. The invention includes a rotary-dividing table comprising a housing with a faceplate disposed therein associated with a rotational reduction gear through a Maltese mechanism consisting of slats rigidly attached to the faceplate that interact with a leash mounted on the rotational reduction shaft and a faceplate retainer connected through a cam with a rotational gear, characterized in that, in order to simplify the design and increase its reliability, the table is equipped with a two-arm lever mounted in the housing with the possibility of one arm interacting with f ksatorom, and others - leash Geneva mechanism, said lead take mounted possibility w reciprocating movement along the shaft axis.
