Abstract
A device for assembling cams on a camshaft pipe of a camshaft may include a first gripper and a second gripper each configured for gripping and holding a respective cam. The first gripper and the second gripper may receive the respective cam in a common direction and may be movable in a common direction into alignment with respect to the camshaft pipe. The second gripper may be configured to grip and hold the respective cam that is pivoted by 90° with respect to an orientation of the respective cam in the first gripper.
Claims20
A device for assembling cams on a camshaft pipe of a camshaft, comprising:
- a first gripper and a second gripper each configured for gripping and holding a respective cam during assembly, wherein the first gripper and the second gripper receive the respective cam in a common direction and are movable in a common direction into alignment with respect to the camshaft pipe, and the second gripper grips and holds the respective cam that is pivoted by 90° with respect to an orientation of the respective cam in the first gripper;
- and
- wherein the second gripper comprises a U-shaped seat and a U-shaped holder, and the U-shaped holder is movable axially and radially with respect to the U-shaped seat.
A method for joining cams on a camshaft pipe via an assembly device, comprising:
- providing a first gripper and a second gripper configured to mount at least two cams, the second gripper comprising a U-shaped seat and a U-shaped holder, wherein the U-shaped holder is movable axially and radially with respect to the U-shaped seat;
- heating the at least two cams;
- positioning a first of the at least two cams in the first gripper and a second of the at least two cams into the second gripper that is pivoted by 90° with respect to the first cam;
- moving the first gripper and the second gripper into alignment with the camshaft pipe;
- pushing the camshaft pipe through the at least two cams mounted in the first gripper and the second gripper;
- and
- performing a temperature equalisation for a predetermined waiting period until the at least two cams shrink-fit onto the camshaft pipe to define a fixed connection.
A gripper of an assembly device for mounting a cam on a camshaft, comprising:
- a U-shaped seat and a U-shaped holder, wherein the U-shaped seat and the U-shaped holder are movable axially and radially relative to one another with respect to a longitudinal axis of the camshaft.
