СТАНОКMACHINE

1one

Изобретение относитс к станкостроению и может быть использовано на токарно-револьверных станках с автоматическим управлением .The invention relates to a machine tool industry and can be used on automatic turret lathes.

По основному авт. св. № 562384 известен автоматический токарно-револьверный станок 1.According to the main author. St. No. 562384 is known automatic turret lathe 1.

Однако известное устройство обеспечивает надежность его работы, так как при несовпадении заданного взаимного расположени обрабатываемой детали и инструмента возможно перемещение инструмента на деталь и, как следствие, разрушение инструмента .However, the known device ensures the reliability of its operation, since if the specified relative position of the workpiece and the tool do not match, it is possible to move the tool to the part and, as a result, to destroy the tool.

Цель изобретени - повышение надежности работы станка и улучшение условий его эксплуатации.The purpose of the invention is to increase the reliability of the machine and improve its operating conditions.

Поставленна цель достигаетс те.м, что станок снабжен блоком индексации, а насос гидросистемы посредством одного из электромагнитных распределителей и блока индексации св зан с блоками ускоренных и рабочих перемещений суппорта и ускоренного и рабочего поворота револьверной головки и их исполнительными гидроцилиндрами , причем блок индексации выполнен в виде группы регулируемых кулачков, закрепленных на барабане револьверной головки, и датчика, установленного на суппорте с возможностью его взаимодействи с регулируемыми кулачками.The goal is achieved by the fact that the machine is equipped with an indexing unit, and the hydraulic system pump is connected to one of the accelerated and working movements of the caliper and the accelerated and working turn of the turret and their actuating hydraulic cylinders by means of one of the electromagnetic distributors and the indexing unit. as a group of adjustable cams mounted on a turret drum and a sensor mounted on a caliper with the possibility of its interaction with adjustable cams mi

Устройство содержит насос 1 гидравлической системы автоматического токарноревольверного станка, соединенный с электромагнитными распределител ми 2 и 3.The device comprises a pump 1 of a hydraulic system of an automatic turning-screw-hole lathe connected to electromagnetic distributors 2 and 3.

Claims

Electromagnetic valve 2 is connected via indexing unit 4 to block 5 of accelerated and working movements of support 6 and their actuating hydraulic cylinder 7, and electromagnetic valve 3 is connected to blocks 8 of accelerated and operating turn of the turret 9 and their actuating hydraulic cylinder 10, and the unit 5 accelerated and working movements of the caliper 6 is equipped with a cam 11 with the possibility of its interaction with the blocks 8 of the accelerated and working rotation of the turret 9, a - block 8 of the accelerated rotation of the turret goal The rods 9 are equipped with two groups of cams 12 and 13 with the possibility of their interaction with the blocks 5 of the working movements of the slide 6 and the output mechanism of the latch 14 of the turret 9. The indexing unit 4 is designed as a group of adjustable cams 15 fixed to the drum of the turret 9, sensor 16, fixed on the support 6 of the machine and connected with the blocks 5 accelerated and working movements of the support 6, blocks 8 of the accelerated and working turn of the turret 9 and their actuating hydraulic cylinders 7 and 10. The switch-on unit eyes feed is formed as a group of cams 12 and the sensor 17 fixed to the frame. Starting position - caliper 6 on a hard stop (extreme down position). The pump 1 of the hydraulic system of the machine through the electromagnetic distributor 2 through the block 5 accelerated and working movements and its actuating hydraulic cylinder moves the caliper 6, its removal from the fixed stop. When leaving the cutting zone, the cam 11 of the block 5 interacts with the sensor 18 of the block 8 of the accelerated and working rotation of the turret 9, which, through its actuating hydraulic cylinder 10, accelerates the rotation of the turret 9 before the interaction of one of the group of cams 13 of the block 8 with the release mechanism 14 turret 9. A change occurs. turret tool positions 9. One of the group of cams 15 of the indexing unit 4, mounted on the turret drum 9, through the sensor 16, mounted on the caliper 6, communicates with the accelerated unit 5 and the working movements of the caliper 6, which through the electromagnetic distributor 2 and its executive the hydraulic cylinder 7 accelerates the movement of the caliper 6 to the working feed zone until one of the cams 12 of the said group of block 5 interacts with its sensor 17 fixed on the frame, It will not turn on the working feed of the caliper. The number of cams 12, 13 and 15 - the value is variable and depends on the number of technological transitions and the type of workpiece. In this case, the caliper will move with a value equal to the size of the working feed until it stops at the hard stop. The block 8 of the working rotation of the turret 9 is activated when the caliper 6 is positioned on the hard stop while the latch-output mechanism 10 is triggered. of the same block, which excludes the possibility of switching on the block 5 displacements, and the caliper 6 remains in its extreme position until this mismatch (mismatch of positions) is The country is working. This eliminates the possibility of tool destruction and subsequent machine failure. Due to the application of the proposed technical solution in the machine, the command for the longitudinal movement of the slide to the work feed zone is carried out only on condition that the position of the tool is in relation to the workpiece, excluding the possible destruction of the tool, which ensures reliable operation of the machine and improves its operating conditions. Invention Formula Automatic turret lathe according to aut. St. No. 562384, characterized in that, in order to increase the reliability of operation and improve the operating conditions of the machine, it is equipped with an indexing unit, and the pump of the hydraulic system of the machine through one of the electromagnetic distributors and the indexing unit is connected with blocks of accelerated and working caliper movements and accelerated and working rotation of the turret and their performer, hydraulic cylinders, and the indexing unit is designed as a group of adjustable cams mounted on the turret drum and sensor installed lennogo on the support with the ability to interact with the adjustable cams.
