Изобретение относитс к деревообрабатывающей промышленности и, в частности к оборудованию дл выборки пазов.The invention relates to the woodworking industry and, in particular, to equipment for the selection of grooves.

Известен сверлильно-пазовальиыЯ станок, включающий станину, пневматический и гидравлический цилиндры, пиноль и привод 11 .Known drilling-grooving machine, including a frame, pneumatic and hydraulic cylinders, quill and drive 11.

Известно также устройство дл перемещени ПИНОЛИ сверлильно-пазовального станка,, включающее станину с плитой, пневмо- и гидроцилиндры с Корпусом и штоками, кронштейн и рычаг возврата пиноли в исходное положение , емкость и привод 21 .It is also known a device for moving the PINOLI of a drilling-grooving machine, which includes a bed with a plate, pneumatic and hydraulic cylinders with a housing and rods, a bracket and a lever for returning quill to its original position, capacity and drive 21.

Недостатками известных устройств вл ютс большие габариты и низка равномерность перемещени пиноли.The disadvantages of the known devices are the large size and low uniformity of movement of the quill.

Цель изобретени - уменьшение габаритов и повышение равномерности перемещени пиноли.The purpose of the invention is to reduce the size and increase the uniformity of movement of the quill.

Цель достигаетс тем, что шток пиевмоцилиндра выполнен полым, -гидроцилиндр размещен в полости штока пневмоцилиндра, при этом корпус пневмоцилиндра и шток гидроцилиндра закреплены жестко на плите, на конце штока пневмоцилиндра установлены гайки , причем один конец кронштейна выполнен в виде вилки, котора свободно размещена между гайками штока пневмоцилиндра и его корпусом, а другой - жестко соединен с пинолью.The goal is achieved by the fact that the rod of the cylinder cylinder is hollow, the hydraulic cylinder is placed in the cavity of the pneumatic cylinder stem, while the pneumatic cylinder body and hydraulic cylinder rod are rigidly fixed on the plate, nuts are installed at the end of the pneumatic cylinder rod, and one end of the bracket is in the form of a fork that is freely positioned between pneumatic cylinder stem nuts and its body, and the other is rigidly connected to the quill.

Устройство включает станину 1 с плитой 2, на которой установлены пневмоцилиндр 3 и гидроцилиндр 4 с корпусом 5, штоком 6 пневмоцилинд15 ра 3, причем шток б выполнен полым н штоком 7 гидроцилиндра 4. Сбоку корпуса 5 смонтирован кронштейн 8 и рычаг 9 возврата пиноли 10 в исходное положение и емкость 11. Гидроцилиндр The device includes a frame 1 with a plate 2 on which a pneumatic cylinder 3 and a hydraulic cylinder 4 with a housing 5, a rod 6 pneumatic cylinders 15 ra 3 are installed, and the rod b is made hollow n the rod 7 of the hydraulic cylinder 4. On the side of the housing 5 is mounted a bracket 8 and a lever 9 for returning quills 10 initial position and capacity 11. Hydraulic cylinder

20 4 размечен в полости штока б пневмоцилиндра 3, корпус 5 которого и шток 7 гидроцилиндра 4 закреплены жестко на плите 2. На конце штока 6 пневмоцилиндра 3 установлены гайки 12. Один конец кронштейна 7 выполнен в виде вилки 13, концы которой свободно размицены между гайками 12 штока б пневмоцилиндра 3 и его корпусом 5, а другой - жестко 20 4 is marked in the cavity of the stem b of the pneumatic cylinder 3, the body 5 of which and the rod 7 of the hydraulic cylinder 4 are fixed rigidly on the plate 2. At the end of the rod 6 of the pneumatic cylinder 3, nuts 12 are installed. One end of the bracket 7 is made in the form of a fork 13, the ends of which are stretched between the nuts 12 rod b pneumatic cylinder 3 and its body 5, and the other - hard

Claims

30 is connected to the quill 10. The device works as follows. When air is supplied to the upper cavity of the pneumatic cylinder 3, the piston and rod 6 move downward, at this force of the pneumatic cylinder 3 is transferred by means of the bracket 8 to the quill 10 and the latter moves downward, along with the bracket 8 the quill return lever 10 moves to its original position. When moving the rod 6 of the hydraulic cylinder 3, the oil from the upper cavity of the hydraulic cylinder 4 through the system of the Trunks and the container 11 enters the lower cavity of the hydraulic cylinder 4, ensuring uniform flow. When air is supplied to the lower cavity of the pneumatic cylinder 3, the piston and rod 6 move upwards and the cycle is repeated. The invention The device for moving the pintles of a drilling-grooving machine, including a bed with a plate, a pneumatic hydraulic valve with a housing and rods, a bracket and a lever for returning the pintles to their original position, capacity and drive, with a view to reducing the size and evenness the quill movement, the pneumatic cylinder stem is hollow, the hydraulic cylinder is placed in the cavity of the pneumatic cylinder rod, while the pneumatic cylinder body and the hydraulic cylinder rod are fixed rigidly on the plate, at the end of the pneumatic cylinder rod The nuts are fixed, with one end of the bracket made in the form of a fork, which is freely placed between the nuts of the pneumatic cylinder stem and its body, and the other is rigidly connected to the quill.
