Изобретение относитс к области станкостроени , в частности к устройствам дл обработки тонкостенных консольно закрепленных деталей типа цанг механического карандаша .The invention relates to the field of machine tool construction, in particular, to devices for processing thin-walled cantilever-mounted parts such as the collets of a mechanical pencil.

Известны устройства дл фрезеровани продольных пазов с фиксатором обрабатываемой детали и шпиндельной насадкой, размешенной на пиноли.Devices are known for milling longitudinal grooves with a fixture of the workpiece and a spindle nozzle placed on quills.

Однако известные устройства не позвол ют фрезеровать торцовые прорези в тонкостенных , консольно зажатых детал х.However, the known devices do not allow milling of the end slots in thin-walled, cantilevered parts.

Дл создани возможности фрезеровани пазов в тонкостенных консольных детал х шпиндельна насадка выполнена с направл юшим элементом в виде вилки, обхватывающей пиноль, а фиксатор подпружинен и расположен на последней. Кроме того, рабочий конец фиксатора выполнен по форме участка обрабатываемой детали, сопр гаемого с фиксатором , и снабжен сквозными прорез ми дл прохода фрез.To create the possibility of milling grooves in thin-walled cantilever parts, the spindle attachment is made with a directional element in the form of a fork, gripping the quill, and the lock is spring-loaded and located on the latter. In addition, the working end of the retainer is made in the shape of the section of the workpiece that mates with the retainer, and is provided with through slots for the passage of cutters.

На фиг. 1 изображено предлагаемое устройство , общий вид; на фиг. 2 - часть устройства с фиксатором и инструментом в рабочем положении; на фиг. 3 - разрез по А-А на фиг. 2; на фиг. 4 - вид по стрелке Б на фиг. 1.FIG. 1 shows the proposed device, a general view; in fig. 2 - part of the device with a lock and tool in the working position; in fig. 3 is a section along A-A in FIG. 2; in fig. 4 is a view along arrow B in FIG. one.

Устройство дл фрезеровани пазов состоит из пиноли 1, 3 полости которой посредством пружины 2 сжати установлен фиксатор 3. Нижний его конец имеет торцовый сквозной,паз 4 с продольной осью, совпадающей с продольной осью фиксатора 3, дл направлени раооче; инструмента, а в его торце по периметру выполнена проточка, образующа кольцевое углубление с внутренней стенкой в виде распорного элемента 5 дл приема и фиксации совместно с наружной стенкой проточки, конца обрабатываемой детали 6, имеющей центральное отверстие.A device for milling grooves consists of quill 1, 3 cavities of which by means of a spring 2 squeeze a latch 3 is installed. Its lower end has an end through slot, a groove 4 with a longitudinal axis coinciding with the longitudinal axis of the latch 3, in order to guide it more; tool, and at its end around the perimeter there is a groove, forming an annular recess with an inner wall in the form of a spacer element 5 for receiving and fixing, together with the outer wall of the groove, the end of the workpiece 6 having a central hole.

Корпус пиноли I выполнен с консолью 7 на которой жестко закреплен блок привода 8 имеющий электродвигатель 9, зубчатую передачу Ю и режущий инструмент в виде фрез 11 и 12, вход щих в сквозной торцовый паз 4 фиксатора 3.The body of the quill I is made with a console 7 on which the drive unit 8 is rigidly fixed, having an electric motor 9, a gear unit Yu and a cutting tool in the form of mills 11 and 12, which are included in the through end groove 4 of the lock 3.

Claims

The drive unit 8 is provided with a guide element 13, made in the form of a plug, fixing the drive unit 8 relative to the quill 1 in two directions in a plane perpendicular to the longitudinal axis of the part. In the direction of the longitudinal axis of the part, the drive unit 8 with the cutters 11 and 12 is fixed relative to the quill 1 by a rigid chain formed by the elements of quill 1 and the drive unit 8 when installed on the quill console 7 quill 1. The feed hole 14 is made in the upper part of the latch body 3 lubricating coolant flowing through the channel 15 in the housing quill 1. The device operates as follows Pinol 1 together with the drive unit 8 performs a reciprocating motion. When moving down, the latch 3 is lowered onto the part 6 secured in the rotary table collet 16 having a previously formed through hole along its longitudinal axis. Further advancement of the quill 1 with the drive unit 8 downwardly compresses the spring 2, thus providing the necessary clamping force and centering the part 6. Simultaneously rotating milling cutters 11 and 12, which pass from two sides into the through groove 4 of the fixture, 3, mills the slots. Quick and accurate installation of the cutting tool 11 and 12 relative to the groove 4 of the quill 1 provides a guiding element 13. Claim 1: A device for milling the slots containing a spindle bit placed on the quill and a fixture of the workpiece, characterized in that the possibility of milling grooves in thin-walled cantilever parts, the spindle nozzle is made with a guiding element in the form of a fork, gripping the PINOLE, and the lock is spring-loaded and located on the latter.

2. The device according to claim 1, characterized by the fact that the working end of the lock is made in the shape of the section of the workpiece that mates with the lock, and is provided with through slots for the passage of cutters.
