Abstract
A rotary index table comprising a plate, which has drivers that engage with a drive groove of a cam barrel, wherein the plate can be driven by the cam barrel to carry out a rotational movement about a rotational axis which in turn can be driven by a motor to carry out a rotational movement about the longitudinal axis thereof, and wherein the motor directly drives the cam barrel.
Claims3
A rotary indexing table having a plate which has drivers engaging into a driving groove of a barrel cam, wherein the plate is driven via the barrel cam to make a rotary movement about an axis of rotation which is in turn driven by a torque motor to make a rotational movement about its longitudinal axis,
- wherein
- the torque motor comprises magnets that cooperate with corresponding coils to generate a driving force to directly drive the barrel cam without a transmission,
- the barrel cam has a prolongation which has a same outer diameter as that of the barrel cam and the magnets of the torque motor are disposed on the prolongation of the barrel cam, and
- the prolongation and the barrel cam are unitary components.
