Description

Изобретение относится к обработке материалов резанием и может быть использовано при токарной обработке деталей.The invention relates to the processing of materials by cutting and can be used in turning parts.

Цель изобретения - сокращение времени на перева кадку.The purpose of the invention is the reduction of time for transferring the tub.

На держже представлен предлагаемый патрон, осевой разрез.The holder shows the proposed cartridge, axial section.

Патрон содержит корпус 1, который крепится болтами 2 к шпинделю станка (на чертеже не показан). В корпусе 1 патрона смонтированы три ползуна 3, приводимые в действие поршнем 4. Поршень 4 снабжен пластиной 5 с тремя толкателями 6. Пластина 5 крепится к поршню болтами 7. Шток поршня 4 снабжен конечным выключателем 8. На корпус патрона ставится защитная крышка 9, закрепляемая болтами 10. Каждый ползун 3 ¹⁵соединен со сменным кулачком 11 посредством сухаря, имеющего цилиндрическую часть 12 и Т-образное основание 13, размещенное в сменном кулачке 11. Сменный кулачок 11 прижимается к ползуну 3 пру- ₂θ жиной 14, взаимодействующей с втулкой 15. На ползунах 3 и сменных кулачках 11 выполнены рифления 16.The cartridge contains a housing 1, which is bolted 2 to the spindle of the machine (not shown). Three sliders 3, driven by the piston 4, are mounted in the cartridge case 1. The piston 4 is equipped with a plate 5 with three pushers 6. The plate 5 is bolted to the piston 7. The piston rod 4 is equipped with a limit switch 8. A protective cover 9 is attached to the cartridge case, which is fixed bolts 10. Each slider 3 ^{15 is} connected to the replaceable cam 11 by means of a cracker having a cylindrical part 12 and a T-shaped base 13 located in the replaceable cam 11. The replaceable cam 11 is pressed against the slider 3 by a spring ₂ θ 14 interacting with the sleeve 15 On sliders 3 and c ennyh cams 11 are formed corrugations 16.

Патрон работает следующим образом.The cartridge works as follows.

Зажим и освобождение деталей в патроне производятся от привода, установленного на заднем конце шпинделя токарного станка с ЧПУ (на чертеже не показан). Поршень 4, снабженный пластиной 5 с тремя толкателями 6, движется под действием привода токарного станка к переднему торцу 30 патрона 1. Толкатели 6 входят в отверстие в патроне и нажимают на втулку 15, которая, двигаясь вместе с поршнем 4, сжимает пружину 14, а последние в свою очередь перемещают сухарь 12 в осевом направлении в ⁵ сторону переднего торца патрона. В результате сменные кулачки 11 выходят из зацепления с Т-образным основанием 13 и зубчатыми рифлениями 16 ползуна 3 и кулачка 11 и ослабляются. После этого сменный кулачок 10 11 можно переставить на другой типоразмер или заменить. Затем поршень 4, двигаясь в обратном направлении от переднего торца патрона, освобождает сухарь 12 с пружинами 14, которые прижимают ползун 3 к кулачку 11.The clamp and release of parts in the chuck are made from a drive mounted on the rear end of the spindle of a CNC lathe (not shown in the drawing). The piston 4, equipped with a plate 5 with three pushers 6, moves under the action of the lathe drive to the front end 30 of the cartridge 1. The pushers 6 enter the hole in the cartridge and press the sleeve 15, which, moving together with the piston 4, compresses the spring 14, and the latter in turn move the cracker 12 in the axial direction to the ^5th side of the front end of the cartridge. As a result, the interchangeable cams 11 disengage from the T-shaped base 13 and the serrated grooves 16 of the slide 3 and the cam 11 and loosen. After that, the replaceable cam 10 11 can be rearranged to another standard size or replaced. Then the piston 4, moving in the opposite direction from the front end of the cartridge, releases the cracker 12 with springs 14, which press the slider 3 to the cam 11.

Claims

The invention relates to the processing of materials by cutting and can be used in the processing of parts. T.sh. ; :: 1brother - time reduction by neptM:; i ;; i; i -.v. On e |) i; / Kc presents the proposed cartridge, ossg; th section. The cartridge contains a corn 1, which is fastened with bolts 2 to the machine spindle (not shown in the drawing). In the housing 1 of the cartridge, three sliders 3 are mounted, actuated by the piston 4. The piston 4 is provided with a plate 5 with three pushers 6. The plate 5 is fastened to the piston with bolts 7. The piston rod 4 is equipped with a horse switch 8. A protective cover is placed on the housing 1 of the atron 9, fastened with bolts 10. Each slider 3 is connected to the interchangeable cam 11 by means of a cracker having a cylindrical part 12 and a T-shaped base 13 placed in the interchangeable cam 11. The replaceable cam 11 is pressed against the slider 3 by a spring 14 cooperating with the sleeve 15. On the sliders 3 and interchangeable kul chkah 11 are corrugations 16. The cartridge is as follows. The clamping and releasing of the parts in the chuck is made from a drive mounted on the rear end of the spindle of the CNC lathe (not shown). The piston 4, provided with a plate 5 with three pushers b, moves under the action of a lathe drive to the front end of the chuck 1. The pushers 6 enter the hole in the chuck and press the sleeve 15, which, moving with the piston 4, compresses the spring 14 , and the latter in turn move the cracker 12 in the axial direction towards the front end of the cartridge. As a result, the interchangeable cams 11 are disengaged from the T-shaped base 13 and the notched ribs 16 of the slide 3 and the cam 11 and loosened. After that, the interchangeable cam 11 can be moved to another size or replaced. Then the piston 4, moving in the opposite direction from the front end of the cartridge, releases the cracker 12 with the springs 14, which press the slider 3 to the cam 11. The invention Three-cam retractable turning cartridge, in the case of which are located sliders movable from the piston of the drive piston associated with interchangeable cams by means of crackers having a cylindrical part and a T-shaped base, characterized in that, in order to reduce the time for changeover, the device is provided with spring-loaded bushings installed in sliders, rednaznachennymi for receiving therein the cylindrical portions of crackers, and the piston is placed introduced into the apparatus plate with the sliders intended for cooperating with an indication .mi bushings.
