/ Preskopf carrier

The invention relates to a milling head carrier, in particular For universal tool milling machines with milling heads arranged next to one another.

Known are multi-spindle milling heads in which the milling spindles are preferably on a pitch circle with the same Pitch are arranged around a central wheel. With this Arrangement, it is only possible to carry out certain similar operations · Got ?, are still swiveling milling heads with several spindles for vertical milling machines, with the spindles here are arranged side by side. A drive is used for the movement via bevel gears to a spindle and transferred to the following spindles via intermediate gears. This solution has the defect that only certain operations with fixed spindles can be carried out on certain machines, here vertical milling machines. The universal replaceability is not guaranteed.

They are also known for processing several workpieces

Preskopfträger that carry multiple Preskeads. The drive movement is implemented with its own drive for each milling head · The disadvantages are that when converting very long changeover times occur and the arrangement is costly due to the drive that each prehead has and becomes uneconomical.

The invention is based on the object of creating a universally applicable pre-head carrier for milling machines, in which several interchangeable milling heads arranged next to one another are driven by a central drive can be.

According to the invention this is achieved in that a bearing flange on the pre-head carrier for the attachment and the centering attached to the respective machine. In this bearing flange a drive spline is attached, which the Connection with the machine main spindle is used and continues with a drive gear, which with an inner profile, which is used to connect to an exchangeable prehead, is provided, is connected. via intermediate gears the drive gear is connected to receiving gears, which also have an inner profile for receiving interchangeable pres heads included equipped.

A special embodiment of the invention consists therein the intermediate wheels are arranged so that they can be disengaged to stop individual prebeads. To different To achieve speeds of the individual milling spindles, the drive gear and the receiving gear are interchangeable arranged.

The invention creates an Iräekopfträger for milling machines »in which the own drive is omitted and the changeover times are short. Furthermore is by simply attaching the milling head carrier to any pre-machine, such as console milling machines, vertical « milling machines etc. and through the cultivation of various Köpfeav like butt heads, Sehnellfräsköpf uew * on the Milling head carrier, universal replaceability possible. Another advantage is the possibility of machining several workpieces, one of which is several Workpieces can be machined with the same tools and, on the other hand, a workpiece with several tools can be edited

The invention is to be explained in more detail below using an exemplary embodiment Drawing shows the front view in partial section

A bearing flange 2 is attached to the milling head carrier 1. The drive spline shaft 3 is fastened in the bearing flange 2. The drive spline shaft 3 is connected to the drive gear 4 »which is provided with an inner profile 5. The mounting plate 6 contains the holes 7 for the inclusion of the milling head ·. The drive gear 4 is via intermediate gears 8 which are attached to shafts 9, connected to external receiving gears 10 · The receiving gears 10 also have an inner profile incorporated.

This device works as follows: The main spindle of the milling machine is driven by the Drive spline shaft 3, which is fastened in the bearing flange 2, is connected to the milling head carrier 1. The drive is transmitted from the machine main spindle via the drive wedge 3 to the drive gear 4. The transmission of the movement is carried out by the drive gear 4 via intermediate gears 8 on the external receiving tooth

wheels 10 The drive movement is thus transmitted from the main machine spindle to several adjacent milling heads The milling head carrier 1 can be attached to various milling machines, such as Eonsol milling machines, vertical milling machines, etc., and can be equipped with different heads such as pushing heads, high-speed milling heads, etc. Either the same operations with the same tools can be carried out on several workpieces can be executed or a workpiece can be machined with several tools.

The milling head carrier 1 can continue to graze equipped with a Kagel mount and thus also be attached to single-purpose milling machines. It is also possible to exchange the gears in order to achieve different speeds of the milling spindles · In one Special embodiment of the invention, the intermediate gears 8 can be disengaged so that a Milling heads that are not in use are shut down.
