Abstract
An alignment tool determines the parallelism between the anvil face of an anvil of an ultrasonic welder and the horn faces of a replacement horn mounted on the welder by a rotary mount. The tool includes a tool base having a face plate contacting with the anvil face and a clamp for clamping the tool base on the anvil. A plate member is mounted on the tool base for swiveling movement and contacts the horn faces. Springs urge the plate member into contact with the horn faces while the replacement horn is rotated relative to the anvil. Transducers sense the relative positions between the face plate and the plate member so that the repairman can determine that the replacement horn has been rotated to the desired position in which the horn face has become parallel with the anvil face. Then the replacement horn can then be tightened against further rotation.
