Problems solved by technology

However, said pipe extending over the working area requires sufficient space in the protective compartment and presents a risk of collision when machining bulky workpieces
Furthermore, the tubes are exposed to the media present in the protective compartment and can thus be damaged by swarf generated during milling operations and possibly also by other working storage

Embodiment Construction

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which a machining unit for a drilling and milling machine is schematically illustrated in longitudinal section.

[0010] The illustrated machining unit comprises a spindle housing 1 which is arranged on the assembly of the drilling and milling machine via guide rails (not shown) and is guided and slidable in the longitudinal direction. The spindle drive 2 is used for the longitudinal movement of the machining unit, which in this case contains a so-called recirculating ball screw driven by an electric motor 3 via a belt drive 4 . At the left end of the spindle housing 1 in the figure, a vertical milling head 5 is mounted and rotatable about a horizontal axis into selectable operating positions. A work spindle 6 is supported in this milling head 5 , which is driven by an internal motor and has a tool-holding clamp 7 at its lower end.

Abstract

The subject-matter of the invention is a machining unit for a milling and drilling machine, comprising a spindle housing (1) which is supported on a machine part and can be moved in a longitudinal direction, a milling head (5) mounted on the face end of the spindle housing (1), a work spindle (6) supported in the milling head (5) and comprising an electric drive motor, and an energy and working stock supply to the milling head (5) formed of bunched lines and cables. The bunched lines and cables for the energy and working stock supply are disposed inside the spindle housing (1) in the shape of a string (25) and introduced into the milling head (5) via a rotary transmission leadthrough (8) on the face.

Description

technical field [0001] The invention relates to a machining unit for a drilling and milling machine, comprising: a spindle housing supported on a machine column and movable by a motor; a milling head rotatably mounted on the surface end of said spindle housing; A work spindle, which is supported on the milling head and includes a built-in electric motor; and an energy and fluid supply, the cables of which are surrounded by a cover. Background technique [0002] In drilling and milling machines, energy and flushing fluid are supplied to the spindle head, i.e. the working Spindle and its drive. This cable bundle and the surrounding elastic cover extend from the surface of the machine column into the working area outside the milling head and are rotatably connected to the side wall of the milling head. The connection of the individual energy supply cables and working substance tubes to the respective functional elements takes place inside the milling head. [0003] In a mach...
