A shaft 14 is pressed against the cam 9 profile by a spring 13, on which the pipe centering mechanism 8 is mounted on the other hand. The shaft 14 with the key 15 passes through the internal opening of the worm ¹ of the 16 wheel of the division mechanism 7 and is able to move axially relative to the worm wheel 16 by the distance between two adjacent annular rows of holes. A mounting centering mechanism 17 is mounted on the mounting trolley 6, mounted with the possibility of free rotation of the trolley 6.

Устройство работает следующим образом.The device operates as follows.

Трубу 4 одним концом устанавливают в механизм 8 центрации, а другим - в механизм 17 центрации, оси которых расположены на одном уровне. Затем включается привод сверлильной головки 2 и сверлится, например одним инструментом, отверстие, после чего приводится ₁₅во вращение червяк 12 (привод червяка 12 на чертежах не показан) механизма 7 деления, в результате чего червячное колесо 16 поворачивается относительно своей оси на окружной шаг, передавая при этом свое вращение трубе 4 че- ₂о рез шпонку 15, вал 14, механизме центрации, одновременно с круговым перемещением на величину окружного поля деталь 4 смещается в осевом направлении на расстоянии между двумя соседними кольцевыми рядами за счет того, ?5 что червяк 12, вращаясь и поворачивая червячное колесо 16, одновременно через гитару 11 поворачивает валик 10 с закрепленным на нем кулачком 9 на 180°, а кулачок 9, взаимодействуя с торцом вала 14, перемещает его в осе- ₃₀вом направлении. После этого, как инструмент просверлит последнее отверстие в кольцевом ряду, срабатывает, например, счетчик импуль сов, настроенный на определенное количество просверливаемых отверстий, и дает команду .на срабатывание механизма 3 для перемещения детали 4 относительно сверлильной головки 2 на величину осевого перемещения детали между циклами.The pipe 4 at one end is installed in the centering mechanism 8, and the other in the centering mechanism 17, the axes of which are located at the same level. Drive the drill head is then activated 2 and drilled, such a tool hole, and the drive ₁₅ to rotate the worm 12 (drive worm 12 not shown) dividing mechanism 7, whereby the worm wheel 16 is rotated about its axis at a circumferential pitch transmitting its rotation while the pipe 4 on che ₂ cut the key 15, shaft 14, centering mechanism, simultaneously with a circular movement by the value field circumferential part 4 is displaced axially in the region between two adjacent annular rows a score of? 5 that the worm 12 rotates and rotating the worm wheel 16, simultaneously through guitar 11 rotates with roller 10 fixed to it cam 9 through 180 °, and the cam 9 interacting with the end of shaft 14, moves it in the axial ₃₀ direction. After that, as the tool drills the last hole in the annular row, for example, a pulse counter adjusted to a certain number of drilled holes is triggered and gives a command. To trigger the mechanism 3 to move the part 4 relative to the drilling head 2 by the amount of axial movement of the part between cycles .

Claims

The invention relates to a machine tool industry and can be used to perforate pipes. A pipe perforation machine is known, on a bed of which a separating device with a centering mechanism, mounting carriages, a drilling head and an axial movement mechanism of pipes 1 are placed. However, this device has limited technological capabilities. The purpose of the invention is the expansion of technological capabilities. The goal is achieved by the fact that the machine is equipped with an additional mechanism for reciprocating axial movement of pipes located on one of the installation trolleys, which is kinematically connected with a dividing mechanism mounted on the carriage and installed with axial movement relative to the same carriage centering mechanism. In addition, the device is equipped with an additional centering mechanism placed on another installation trolley with the possibility of free rotation relative to the latter. FIG. 1 shows the proposed machine, a general view; in fig. 2 is a view A of FIG. 1. The device consists of a bed 1, a drilling head 2, a mechanism 3 for axial movement of the pipe 4 after the end of the processing cycle And two installation carts 5 and 6.. On Tepeucca 5, a separating device 7, made in the form of a worm gear, is mounted for centering parts 4, an additional mechanism of reciprocating axial movement of the part 4 during the processing cycle to the distance between two adjacent annular rows of holes, fulfilled in the form of a cam 9, created on roller 0 and kinematically connected through the guitar And with one of the ends of the screw 12 mechanism of the 7th division. A shaft 14 is preloaded to the profile of cam 9 by a spring 13, on which, on the other hand, the mechanism 8 of the center of the pipe 4 is fastened. The shaft 14 with the IS tongue passes through the inner hole of the 16 m wheel of the 7th division and has the ability to rotate axially relative to the worm This wheel 16 is at a distance between two adjacent annular rows of holes. An additional centering mechanism 17 is mounted on the mounting carriage 6 and mounted so that the carriage 6 can freely rotate. The device works as follows ohm The pipe 4 at one end is installed in the mechanism 8 centralzine, and the other in the mechanism 17 centration, the axes of which are located on the same level. Then, the drill driver of the V head 2 is turned on and the hole is drilled, for example with one tool, and the screw is rotated to 12 (the screw drive 12 is not shown in the drawings) of the dividing mechanism 7, resulting in the worm gear 16 on the circuit step. transferring its rotation to pipe 4 via key 15, shaft 14, the centering mechanism, simultaneously with circular movement by the circumferential floor value, part 4 is displaced axially in the distance between two adjacent ring rows due to the fact that the worm is 12, rotating smiling and turning the worm gear 16 at the same time through the guitar and turning the roller 10 with the cam 9 fixed on it by 180 °, and the cam 9, interacting with the shaft end 14, moves it in the axial direction. After that, as the tool drills the last hole in the annular row, a pulse counter, for example, tuned to a certain number of holes to be drilled, triggers the mechanism 3 to move part 4 relative to the drill head 2 to the amount of axial movement of the part between cycles.
