Abstract
Abstract This invention relates to a switch plate machine for rotating workpieces to work stations, e.g., machining stations. The Switch plate is mounted on bearings in the machine frame and is periodically turnable about equal angles. Workpiece receivers, for example chucks, are mounted on the said switch plate at equiangular intervals in axial thrust bearings parallel to the axis of the switch plate with play or tolerance in the radial direction. Centering members secured to the frame can be connected in rotation-resistant manner with any one of the workpiece receivers by an axial movement of the switch plate to center and align the workpiece receivers at each work station.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
190 words
A switch plate machine for rotating workpieces to angularly spaced positions comprising, a machine frame, a switch plate which is journaled in the machine frame such that it can be periodically rotated by equal angular distances and can be reciprocated in the direction of its axis of rotation, means for rotating the switch plate, means for the axial reciprocating movement of the switch plate, a plurality of thrust bearings which are arranged on the switch plate about its axis of rotation at equal angular intervals, a plurality of workpiece receivers each of which is journaled in one of the thrust bearings parallel to the axis of rotation of the switch plate with radial tolerance and Hirth-type serration on its lower face, and a plurality of centering members which are rigidly affixed to the machine frame around the turning axis of the switch plate at equal angular intervals and have Hirth-type serration on their top face which mate axially with the serration of the workpiece receivers after every turn of the switch plate and which can be brought into and out of engagement by an axial movement of the switch plate.
Claim 2
Dependent Claim
190 words
A switch plate machine for rotating workpieces to angularly spaced positions comprising, a machine frame, a switch plate which is journaled in the machine frame such that it can be periodically rotated by equal angular distances and can be reciprocated in the direction of its axis of rotation, means for rotating the switch plate, means for the axial reciprocating movement of the switch plate, a plurality of thrust bearings which are arranged on the switch plate about its axis of rotation at equal angular intervals, a plurality of workpiece receivers each of which is journaled in one of the thrust bearings parallel to the axis of rotation of the switch plate with radial tolerance and Hirth-type serration on its lower face, and a plurality of centering members which are rigidly affixed to the machine frame around the turning axis of the switch plate at equal angular intervals and have Hirth-type serration on their top face which mate axially with the serration of the workpiece receivers after every turn of the switch plate and which can be brought into and out of engagement by an axial movement of the switch plate.
Claim 3
Dependent Claim
23 words
A switch plate machine according to claim 1 wherein the switch plate is elastically resilient in the axial direction near the periphery thereof.
Claim 4
Dependent Claim
32 words
A switch plate machine according to claim 2 wherein the radially outer zone of the switch plate is divided by radial slots into elastic segments each of which carries one workpiece receiver.
