Изобретение относитс к машиностроению и может быть использовано в металлорежущих станках и автоматических лини х дл обработки точных корпусных деталей приборов.The invention relates to mechanical engineering and can be used in machine tools and automatic lines for machining exact body parts of devices.

Известны силовые головки дл обработки деталей, в корпусе которых расположены шпиндельные узлы с инструментальными блоками и фиксаторами, имеющие ловители, приводы подачи и вращени 1.Known power heads for machining parts, in the case of which spindle assemblies with tool blocks and latches are located, have catchers, feed and rotation drives 1.

Недостатком этой головки вл етс то, что она может решать задачу получени требуемой точности взаимного расположени обрабатываемых поверхностей , лежащих только в одной плоскости и не может быть использована дл обработки сложных корпусных деталей , в различных плоскост х, тем более дл обработки поверхностей детали , заданных от различных технологических баз.The disadvantage of this head is that it can solve the problem of obtaining the required accuracy of the relative position of the machined surfaces lying only in one plane and cannot be used for machining complex body parts in different planes, especially for machining surfaces of the part specified from various technological bases.

Целью изобретени вл етс обеспечение возможности обработки корпусных деталей с различными технологическими базами с одного установа, автоматического внесени необходимых изменений расположени инструмента относительно обрабатываемой поверхности и повышени производительностиThe aim of the invention is to provide the possibility of machining body parts with different technological bases from one setting, automatically making the necessary changes in the location of the tool relative to the treated surface and increasing the productivity

Это достигаетс тем, в предлагаемой силовой головке дл обработки деталей, в корпусе которой расположены шпиндельные узлы с инструментальными блоками и фиксаторами, имеющей ловители, приводы подачи и вращени , каждый шпиндельный узел с инструментальными блоками установлен на плоских опорах качени плавающим относительно корпуса с возможностью фиксации на нем (корпусе) в процессе обработки на нем и св зан с приводом вращени гибкой передачей, а ловители установлены на инструментальных блоках шпиндельного узла.This is achieved by the fact that in the proposed power head for machining, in the case of which there are spindle assemblies with tool blocks and latches, having catchers, feed and rotation drives, each spindle assembly with tool blocks is mounted on flat rolling rolling supports relative to the body with the possibility of fixing on it (the housing) during processing on it is connected with the rotational drive by a flexible transmission, and catchers are installed on the tool blocks of the spindle assembly.

Шпиндельный узел с инструментальными блоками, установленный на плоских опорах качени , подпружинен относительно корпуса головки.The spindle unit with tool blocks, mounted on flat rolling bearings, is spring-loaded relative to the head housing.

Claims

The power head contains a feed drive 1 (for example, hydraulic), a spindle rotation drive with a flexible gear 2 (for example, a drive shaft), a spindle assembly 3 with a tool block of the power head 4, connected to the housing 5 by means of springs 6 (stabilizing the initial position), flat rolling bearings 7 and fixing devices 8 (for example, hydraulic cylinders), which fix the spindle unit 3 in the process of machining. The safety device 9 is pressed against the predetermined base surface by the spring 10. The power head may contain several spindle assemblies, depending on the workpiece. The device works as follows (the operation of one spindle assembly is considered, since the operation of all spindle assemblies is similar). When the head is fed to the part, the catcher 9 is mounted on the base surface of the part, after which a signal is given to trigger the fixing devices 8, which fix the spindle assembly rigidly with the body 5 of the power head. Thereafter, the part is machined (e.g., drilling, boring, etc.). The spring 10 presses the safety device 9 to the base surface, and after the power head is retracted, it returns to its original position, while the fixing devices 8 release the spindle unit 3. This completes the work cycle. The execution of the power head along with spindle assemblies and catchers with the possibility of axial movement, and the spindle assemblies with instrumental 1–4 units and catchers floating relative to the body of the power head with the possibility of their fixation in a predetermined position ensures the use of power heads on aggregate machines and automatic lines for machining body parts without relocation, which in turn increases labor productivity, reduces the amount of equipment, and improves machining accuracy. The spring stabilizers in the proposed head provide the middle position of the catchers and a smooth, soft self-installation on the base surfaces of the workpiece. 1. The force head for machining parts, in the case of which spindle units with tool blocks and latches are located and having catchers, feed and rotation drives, in order to enable machining of body parts with different technological bases from one and automatically making the necessary changes in the location of the tool relative to the surface to be machined and increasing productivity, each spindle assembly with tool blocks is set on flat rolling bearings floating relative to the housing with the possibility of fixation during processing on it and connected with a rotational drive by a flexible transmission, and catchers are installed on the tool blocks of the spindle assembly.

2. The head according to claim 1, characterized by the fact that the spindle assembly with tool blocks, mounted on flat rolling bearings, is spring-loaded relative to the head body.
