The present invention relates to an ultrasonic welding apparatus including a horn unit including a horn wherein the horn is configured to contact a target to be welded and a vibrator configured to apply vibration to the horn; an anvil unit including an anvil having an first flat surface on which the target to be welded is configured to be placed and a support portion configured to support the anvil in a rotatable state; and a welding main body configured to have the horn unit and the anvil unit fixed thereto, wherein the anvil is rotated in a state of being supported by the support portion such that the first flat surface of the anvil is parallel to a welding surface of the horn, whereby parallelism between the horn and the anvil may be easily achieved, and welding quality may be improved.

A welding fixture and method allow for both coarse and fine adjustments of headstocks and tailstocks for securing a tank or other cylindrical-like object within a welding fixture. Coarse adjustment is provided by adjusting the headstock and/or tailstock linearly along a rail system. Find adjustment is provided by linearly adjusting a movable table on which the headstock and/or tailstock rest. The headstock and tailstock may also have compression clamping members for securing the tank to the headstock and tailstock. Pipe stands are also provided for supporting the tank before, during, and after the welding process.

A tool welding system is disclosed that includes a table that heats a tool. A multi-axis robot includes a welding head that is moved relative to the table in response to a command. A controller is in communication with the robot and generates the command in response to welding parameters. The weld parameters are based upon a difference between an initial tool shape and a desired tool shape. The difference between the initial tool shape and the desired tool shape corresponds to a desired weld shape. The desired weld shape is adjusted based upon initial tool shape variations, which includes thermal growth of the tool. The tool is welded to provide the desired weld shape to achieve a desired tool shape.

A system for positioning and welding a bracket 30 to a mounting surface, such as a vehicle side rail 40, including using a pivoting tool 20 on a moveable arm 10 that allows the bracket 30 to pivot to minimize the gap between the bracket 30 and its intended mounting surface. The pivoting tool 20 secures, positions near the surface, and allows the bracket 30 to pivot for a precise surface match. A welder 50 welds the bracket 30 to the surface with the gap minimized while the bracket 30 is held in the desired position. The pivoting tool 20 is preferably on an adjustable appendage 12 or combination end 60 mounted on a distal end of the arm 10. The flexible tooling does not require the bracket 30 to be forced with substantial pressure against the mounting surface.

Various embodiments of the present disclosure are directed to a method for producing a ball valve for regulating a fluid. In one example embodiment, the method includes the steps of: providing first and second housing parts of the valve housing, said first and second housing parts each including at least a central housing part and a connection end; providing a valve element shaped as a ball with at least one through-going aperture; arranging the first and second housing parts with the respective central part ends facing towards each other, and further arranging the ball at a position inside an inner space defined by the respective central parts; and welding the first and second housing parts together using a welding tool while performing an interrelated rotation about an axial rotation axis between the position of the first and second housing parts and the position of the ball.

The present invention relates to a positioning device for rotatably and rectilinearly positioning a card with respect to a treatment unit having an axis of treatment. The positioning device comprises a card holder for holding a card in a fixed position, wherein the card holder defines a virtual card surface plane coincident with the surface of a card facing the treatment unit once the card is placed in the card holder, and wherein the card holder defines a virtual card center point coincident with the intersection point of the axis of treatment and the virtual card surface plane. The positioning device further comprises a manipulator to which the card holder is attached, wherein the manipulator comprises: a cardanic element with a first axis of rotation and a second axis of rotation; and a virtual pivot point being the intersection of the first and the second axis of rotation.

An engraving fixture for use with an engraver including a laser moveable along a linear X-axis path wherein the fixture comprises a base structure having two mutually extendable parts to assume different axial lengths thereby to accommodate objects of different lengths. The base can accommodate at an axial mid-point an auxiliary support for especially heavy objects. The base structure includes a support structure carrying the drive wheels and a stepper motor at one end, and a slidable passive support that can be placed at any location on the base member.

A welding system configured to weld a workpiece by using a welding device and a positioner includes a control device configured to control the welding device and the positioner. The positioner includes a workpiece position setting mechanism having reference position information, and at least one holding mechanism configured to hold the workpiece. The control device includes a positioner position calculation means for calculating a position of the holding mechanism when holding the workpiece based on the reference position information provided from the workpiece position setting mechanism and workpiece information inputted into the control device in advance.

A T-slot mounting and alignment system for non-rigidly mounting a workpiece or fixture to a work-piece positioner table, welding positioner table or machine tool table having one of more T-slots includes a T-dog, a dog nut, at least one bolt, and at least one fastener. The at least one fastener fastens the T-dog to the workpiece or fixture, and a dog stem of the T-dog extends through a guide slot in the workpiece or fixture and into the T-slot in the table. The dog nut mates with the at least one bolt and tightens to engage a distal end of the dog stem, wherein clearance is provided in the assembled structures to prevent the workpiece or fixture from being tightly clamped against the table. Consequently, compensation for misalignments is possible during setup.

A hydraulic pressure vessel long seam welding jig device having a triangular frame, a pair of hydraulically actuated clamp mechanisms each having a clamp activating hydraulic cylinder operatively associated therewith, whereby each of the clamp mechanisms are positioned on opposite ends of the carriage beam and arranged to hold a workpiece during a long seam welding operation.
