Linear friction welder with helical groove
First Claim
1. A linear friction welding system comprising:
- a power shaft defining a power shaft axis and including a first eccentric portion and a first power transfer portion;
a power transfer rod engaged with the first power transfer portion;
an actuator assembly operably coupled with the power transfer rod and configured to move the power transfer rod axially along the power shaft axis;
a crank including a second eccentric portion operably coupled with the first eccentric portion, and a second power transfer portion engaged with the power transfer rod, the linear friction welding system configured such that axial movement of the power transfer rod causes rotational movement of the crank with respect to the power shaft about the power shaft axis;
a cam follower operably connected to an outer surface of the second eccentric portion; and
a ram operably connected to the cam follower and configured to vibrate along a welding axis.

9. A linear friction welding system comprising:
-
a power shaft defining a power shaft axis and including a first eccentric portion; a crank including a second eccentric portion coupled with the first eccentric portion; a ram operably coupled with the second eccentric portion and defining a welding axis; a memory including program instructions; and a controller operably connected to the memory, and configured to execute the program instructions to control the phased relationship between the first eccentric portion and the second eccentric portion such that the ram does not vibrate along the welding axis while the power shaft is rotating by axially positioning a power transfer rod coupled to the power shaft and the crank along the power shaft axis, establish a first pressure between two components to be welded after controlling the phased relationship such that the ram does not vibrate, and modify the phased relationship such that the ram vibrates along the welding axis after the first pressure has been established. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
