US Patent:

8181841, May 22, 2012

Filed:

Oct 28, 2011

Appl. No.:

13/284158

Inventors:

Stephen A. Johnson - South Bend IN, US
Thaddeus W. Gorski - Hanna IN, US

Assignee:

APCI, LLC - South Bend IN

International Classification:

B23K 20/12

US Classification:

228 21, 2281121, 156 735

Abstract:

A linear friction welding system in one embodiment includes a ram configured to vibrate along a welding axis, at least one rocker arm with a first end portion spaced apart from the welding axis and constrained against movement along the welding axis, and a second end portion which is movable along the welding axis, and a first welding component support member configured to hold a first welding component, the first welding component support member operably connected to the ram and supported by the second end portion of the at least one rocker arm, such that vibration of the ram along the welding axis causes the location of the first welding component support member along an axis orthogonal to the welding axis to vary.

Appl. No.:

13/462655

Inventors:

Stephen A. Johnson - South Bend IN, US
Thaddeus W. Gorski - Hanna IN, US

Assignee:

APCI, LLC - South Bend IN

International Classification:

B23K 20/12

US Classification:

2281121, 228 21, 228 8, 228102

Abstract:

A linear friction welding system and method in one embodiment includes a first motor configured to rotate a first power shaft, a second motor configured to rotate a second power shaft, a memory including program instructions, and a controller operably connected to the first motor, the second motor, and the memory, and configured to execute the program instructions to identify a first current oscillation amplitude of a ram operably connected to the first power shaft and the second power shaft, determine a second desired oscillation amplitude for the ram, determine a minimum shift in relative angle between the first motor and the second motor to achieve the second desired oscillation amplitude, allocate the minimum shift in relative angle between the first motor and the second motor, and control the first motor and the second motor based upon the allocated minimum shift in relative angle.

Appl. No.:

12/868623

Inventors:

Stephen A. Johnson - South Bend IN, US
Thaddeus W. Gorski - Hanna IN, US

Assignee:

APCI, Inc. - South Bend IN

International Classification:

B23K 20/12

US Classification:

228 21, 228 8

Abstract:

A linear friction welding system in one embodiment includes a ram configured to vibrate along a welding axis, a cam follower operably connected to the ram, an eccentric including an eccentric outer periphery operably engaged with the cam follower, and an inner periphery, a first power shaft slidingly engaged with the eccentric, and a second power shaft eccentrically engaged with the inner periphery.
