Изобретение относитс к области т желого станкостроени и может быть использована на продольно-фрезерных станках.The invention relates to the field of heavy machine tool construction and can be used on longitudinal milling machines.

Известны фрезерные головки, включающие корпус и флацец со ступицей, гнезда которого соединены со шпонками фрезерного шпиндел бабки СГЗКонструкци известных головок не позвол ет производить их переустановку без демонтажа. Кроме того, наличие ручного привода с черв чной парой усложн ет конструкцию головки.Known milling heads include a body and a flat hub with a socket, the sockets of which are connected to the keys of the milling spindle of the headstock. Design of known heads does not allow their re-installation without dismantling. In addition, the presence of a manual drive with a screw pair complicates the design of the head.

Цель изобретени - облегчение перестановки головки и упрощение конструкции .The purpose of the invention is to facilitate rearrangement of the head and simplify the design.

С этой целью, предлагаема головка снабжена оправкой с выступами на торцовой части и подпружиненным толкателем дл воздействи на оправку , а в ступице фланца и на его торце выполнены соответственно продольные и поперечные пазы дл выступов оправки .For this purpose, the proposed head is provided with a mandrel with protrusions on the front part and a spring-loaded pusher to act on the mandrel, and longitudinal and transverse grooves for the protrusions of the mandrel are respectively made in the hub of the flange and on its end.

Дл обеспечени безопасности работы , фланец снабжен сухар ми дл ограничени хода оправки.To ensure safe operation, the flange is provided with crackers to limit the travel of the mandrel.

На фиг. 1 представлена головка (положение перед переустановкой), общий вид; на фиг. 2 - сечение А-А на фи г. 1 .FIG. 1 shows the head (position before reinstallation), general view; in fig. 2 - section AA on fi 1.

На шпиндельной бабке 1 посредством болтов 2 закреплен корпус 3 головки. Внутри корпуса 3 располо10 жен фланец k, имеющий гнезда 5, в которые вход т шпонки 6 фрезерного шпиндел 7. Фланец А посредством штифтов (не показаны) соединен со ступицей конической шестерни 8, усIS тановленной на подшипниках в Корпусе 3. Коническа шестерн 8 входит в зацепление с коническим колесом 9, которое закреплено на шпинделе 10 головки. Внутри корпуса расположена On the spindle head 1 by means of bolts 2 is fixed the case 3 of the head. Inside the housing 3 there is a flange k, having sockets 5, into which the keys 6 of the milling spindle 7 enter. Flange A is connected by pins (not shown) to the hub of the bevel gear 8, mounted on the bearings in the housing 3. The conical gear 8 enters meshing with a tapered wheel 9, which is fixed on the spindle 10 of the head. Inside the case is located

Claims

20 mandrel 11 with two protrusions 12 on the front part. The mandrel 11 is fastened with a spindle 13 in the boring spindle 14. Between the flange and the mandrel there are two breadcrumbs 15. A hole with two longitudinal grooves 16 is made in the hub of the flange k, and two transverse slots 17 are made at the end of the flange. located spring loaded. the pusher 18, the flange 19 abutting against the end portion of the mandrel 11. The lower end of the pusher is passed through an opening in the cup 20 placed in the end of the bevel gear 8. The head is set as follows. The mandrel 11 by the protrusions 12 is passed through the longitudinal grooves 16 of the flange, once screwed, installed in the transverse grooves 17 and held with the aid of a spring-loaded pusher 18. For safe operation in order to prevent the mandrel from accidentally exiting the grooves, the heads are attached to the flange With the help of the rod 13 and the mandrel 11c, the tapered shank is brought to the end of the spindle head 1 fixed there by means of bolts. With this, the keys 6 of the milling spindle 7 enter the sockets 5 of the flange k. The head is re-installed in the following order. The bolts 2 are unscrewed, the head comes off the keys 6 of the milling spindle under its own weight and hangs on the protrusions 12. With the course of the boring spindle | Head down, the head is finally released from the centering of relative headstock 1. After that, the spindle of the machine head turns, the boring spindle 14 moves9 64 up, the head is centered in the new position. The final fixation of the head relative to the headstock 1 is carried out with the help of bolts 2. The proposed head is more rigid in design, easier to manufacture and operate, and allows it to be re-installed to a new position without much effort and time, when processing from one installation of several surfaces the details. Claim 1. Milling head, including body and flange with hub, is characterized by the fact that, in order to facilitate reinstallation of the head and simplify the Design, it is equipped with a mandrel with protrusions on the front part and a spring-loaded pusher to act on the mandrel and in the hub the flange and at its end are made respectively longitudinal and transverse grooves for the protrusions of the mandrel.

2. The head of claim 1, which is designed so that, in order to ensure the safety of its operation, the flange is provided with crackers to limit the travel of the mandrel.
