Embodiment Construction

[0051] figure 1 An example of a swivel beam assembly with two drive devices 10 according to the invention is shown. A swivel beam unit 12 is arranged between two opposing drives 10 . The swivel beam unit 12 includes a swivel beam 14 extending horizontally between the drive devices 10 and a swivel table 16 arranged centrally at the swivel beam 14 . It will be further explained in the following that a driving unit is arranged in the driving device 10, and the rotating beam unit 12 can be surrounded by the driving unit. figure 1 A horizontally extending axis of rotation A rotates.

[0052] The swivel beam unit 12 also includes a drive unit (not particularly shown) housed in the swivel beam 14 so that the swivel table 16 can turn around a vertical swivel axis B. As shown in FIG. By turning around the axes A and B, it can be determined that the workpiece tensioned on the rotary table 16 relative to figure 1 The location of the machine tools is not shown in . It is also conceiv...

Abstract

The invention relates to a drive arrangement (10) for a swivel bridge, wherein the drive arrangement (10) comprises a swivel device (26), having a drive-force receiving device (30) which is configured to cooperate with a drive unit (32) for receiving a rotary drive force; and a coupling device (26) which is configured to couple the drive-force receiving device (32) and a swivel bridge unit (12) together for common rotation about a pivot axis (A), wherein the drive arrangement (10) furthermore comprises at least one bearing device (34) which is configured to mount the swivel device (26) in a rotatable manner with respect to a stationary housing region (36) of the drive arrangement (10); and wherein the drive arrangement (10) further comprises at least one clamping device (38) which is configured to selectively fix the swivel device (26) in different rotary positions, wherein the stationary housing region (36) of the drive arrangement (10) has an inner region (20) axially facing the swivel bridge unit (12) and an outer region (20) axially facing away from the swivel bridge unit (12). In this case, the invention provides for both the bearing device (34) and the clamping device (38) to be arranged in the outer region (22) of the stationary housing region (36).

Description

technical field [0001] The invention relates to a drive device for a swivel beam, wherein the drive device comprises a swivel device with a drive force receiving device designed to cooperate with a drive unit for receiving a rotational drive force; and a hitch device, It is designed such that the drive force receiving device and the swivel beam unit are connected to each other for mutual rotation around the axis of rotation, wherein the drive device also includes at least one bearing device designed to allow the rotation device to rotate relative to the stationary housing of the drive device. The region is rotatably supported, and wherein the drive device also includes at least one clamping device designed to selectively fix the rotary device in different rotational positions, wherein the fixed housing region of the drive device has an axial An inner region adjacent to the rotating beam element and having an outer region axially remote from the rotating beam element. Backgro...
