Abstract
Abstract A horizontal drilling and milling machine having a spindle head which can be rotated about an axis set at 45° to a horizontal plane. The spindle head can be arrested in the horizontal and vertical working positions of the spindle sleeve by means of a support housing. The spindle sleeve can be driven via a gear system. The rotary movement of the spindle head is derived from the drive shaft for the spindle sleeve.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
169 words
A horizontal drilling and milling machine, which has a spindle head which can be rotated about an axis set at 45° relative to a horizontal plane; said spindle head, which carries a rotatable spindls sleeve, can be arrested by means of a support housing in horizontal and vertical working positions of said spindle sleeve; a gear system, which includes a drive shaft rotatably mounted in said support housing, drives said spindle sleeve; said drilling and milling machine further comprises: means for rotating said spindle head about an axis of rotation thereof in a rotational movement relative to said support housing, with said means being drivingly connectable to said drive shaft for deriving motive power therefrom; said means for rotating said spindle head including a shaft which effects the rotational movement of said spindle head, and also including an axially, longitudinally movable coupling gear by means of which said drive shaft can be selectively coupled with, and uncoupled from, said shaft which effects the rotational movement of said spindle head.
Claim 2
Dependent Claim
169 words
A horizontal drilling and milling machine, which has a spindle head which can be rotated about an axis set at 45° relative to a horizontal plane; said spindle head, which carries a rotatable spindls sleeve, can be arrested by means of a support housing in horizontal and vertical working positions of said spindle sleeve; a gear system, which includes a drive shaft rotatably mounted in said support housing, drives said spindle sleeve; said drilling and milling machine further comprises: means for rotating said spindle head about an axis of rotation thereof in a rotational movement relative to said support housing, with said means being drivingly connectable to said drive shaft for deriving motive power therefrom; said means for rotating said spindle head including a shaft which effects the rotational movement of said spindle head, and also including an axially, longitudinally movable coupling gear by means of which said drive shaft can be selectively coupled with, and uncoupled from, said shaft which effects the rotational movement of said spindle head.
Claim 3
Dependent Claim
95 words
A drilling and milling machine according to claim 1, which includes a gear arrangement associated with at least a part of said gear system of said drive shaft; in which said shaft which effects the rotational movement of said spindle head is provided with a drive pinion, with rotary movement for said last-mentioned shaft, and hence for its drive pinion, being effected via said coupling gear and said gear arrangement; and in which said spindle head is provided with a toothing with which said drive pinion engages to impart rotary movement to said spindle head.
Claim 4
Dependent Claim
78 words
A drilling and milling machine according to claim 2, in which said support housing is provided with a supporting journal, a longitudinal axis of which is disposed on the axis of rotation of said spindle head, with said supporting journal projecting into the spindle head; and in which said toothing of said spindle head comprises a first gear ring, which is concentrically disposed about said supporting journal, and which has internal teeth for constantly engaging said drive pinion.
Claim 5
Dependent Claim
100 words
A drilling and milling machine according to claim 3, in which said support housing is provided with a plurality of piston-cylinder units which are concentrically disposed, equidistantly from one another, about said supporting journal; each of said piston-cylinder units has a piston rod which extends into said spindle head and is provided with a disk having a second and third gear ring; a first cooperating gear ring, for said second gear ring, is provided on said first gear ring of said spindle head, and a second cooperating gear ring, for said third gear ring, is provided on said support housing.
