Description

Изобретение относитс к станко|Строению , в частности к головкам дл проточки внутренних канавок резцом на сверлильных станках.The invention relates to a machine tool, in particular, to heads for grooving the internal grooves with a chisel on drilling machines.

Известно устройство, содержащее шпиндель, механизм вращени шпиндел в виде водила, соединенного со шпинделем станка, механизм осевого перемещени и механизм радиальной подачи резца tn.A device comprising a spindle, a spindle rotation mechanism in the form of a carrier connected to a machine spindle, an axial displacement mechanism, and a radial feed mechanism of a cutter tn are known.

Недостатком известного устройства вл етс сложность конструкции . Кроме того,оно неудобно в эксплуатации .A disadvantage of the known device is the complexity of the design. In addition, it is inconvenient in operation.

Цель изобретени - упрощение конструкции .The purpose of the invention is to simplify the design.

Указанна цель достигаетс тем, что механизм радиальной подачи в виде подпружиненного сухар с .жестко закрепленными на нем рычагами и гайки , взаимодействующег с последними и установленной с возможностью перемещени на шпинделе, причем сухарь выполнен с коническим отверстиемThis goal is achieved by the fact that the radial feed mechanism in the form of spring-loaded crackers with tightly attached levers and nuts interacting with the latter and mounted with the possibility of movement on the spindle, the cracker being made with a tapered bore

И размещен в шпинделе с возможностью взаимодействи с оправкой, установотенной в шпинделе шарнирно и снабженной коническим участком.And placed in the spindle with the ability to interact with the mandrel, installed in the spindle pivotally and equipped with a conical section.

На чертеже изображена резцова головка, общий вид, продольный разрез .The drawing shows the incisal head, general view, longitudinal section.

Резцова головка содержит оправку 1, несущую резец 2, снабженную коническим участком 3 и закреп:-ен10 ную в шпинделе 4 на поворотном пальце 5. На наружном диаметре шпиндел 4 нарезана резьба, на которой размещена гайка 6. Рычаги 7 жестко св заны с сухарем.8, размещенным в The cutter head contains a mandrel 1, a carrier cutter 2, provided with a conical section 3 and secured: -10 in spindle 4 on the pivot pin 5. On the outer diameter of the spindle 4 a thread is cut on which the nut 6 is placed. The levers 7 are rigidly connected to the cracker. 8 hosted at

15 шпинделе 4 с возможностью перемещени , при этом рычаги 7 имеют возможность свободно перемещатьс по пазам 9 шпиндел 4. Оправка 1 размещаетс под углом к оси шпиндел 4 за счет The 15 spindle 4 is movable, while the levers 7 are able to move freely along the slots 9 of the spindle 4. The mandrel 1 is placed at an angle to the axis of the spindle 4 due to

Claims

thirty . spring 10, so that the cutter 2 has the ability to freely enter into the hole details, not hitting its walls. Rusk 8 is pressed to the top 39 position by the spring 11. The spindle 4 is connected to the spindle of the machine by means of a carrier 12 and, in order to create greater rigidity, is mounted in the guide sleeve 13. The cutting head operates as follows. Before machining, the nut 6 is retracted to the upper position, the hole of the part is coaxial with the axis of rotation of the spindle of the device, and a cutter 2 is inserted into this hole, shifted relative to the axis of rotation of the spindle by means of a spring 10 at a certain angle, allowing it to freely enter the hole Cracker 3 firmly the spring 7, which is pressed into the upper position with the hook 7 and together with them is not in contact with the conical surface 3 of the mandrel 1. When starting the machine, the torque through the carrier 12 is transmitted by the spindle 4, which is turned aets together with the nut 6. When braking, for example a hand, the nut moves along the threaded outside diameter of spindle spinning its working part lever 7, and hence the biscuit 8 downwards. The rusk 8, with its bevels, acts on the conical surface 3, putting the mandrel 1 in a vertical position, due to which the cutter 2 cuts into the part, digging a groove in it to the desired depth due to the stroke of the nut. When the machine is turned off, the nut is manually or reversely retracted, thereby releasing the levers 7 and the cracker 8, the spring 11 thus pressing the cracker to the upper position, which frees the tapered surface 3. Under the action of the spring 10, the lever 1 is displaced to a definite angle, the cutter output 2 from a groove machined into the part, and the part is removed from the table without damaging its inner surface. The adaptation greatly simplifies the process of grooving the internal grooves and allows their depth to be varied within the limits caused by the flywheel, and also with this design of the radial feed mechanism, the design of the device is simplified. Claims of the invention: A reztsov head containing a mandrel and a mandrel and a radial tool feeding mechanism placed in a spindle, externally threaded with a thread, which, in order to simplify the design, the radial feed mechanism is designed in the form of spring-loaded crackers with levers rigidly fixed on it and the nuts cooperating with the latter and mounted for movement on the spindle, the cracker being made with a tapered bore and placed in the spindle with the possibility of interacting with the mandrel mounted in The spindle is articulated and fitted with a conical section.
