The assembly includes a weld gun having first and second electrodes movable relative to one another between an open position and a closed position. The first electrode includes a housing assembly. A pin is received in the housing assembly and is movable when in said closed position between a desired nut position, and upside down nut position, and a no nut position. An optical sensor has a terminal end space from the pin for direction light thereon. The terminal end of the sensor received reflected light from the pin. A sensor control system processes the reflected light into a signal corresponding to one of the desired nut, upside down nut, and no nut positions.

摘要： An adaptable, servo-control system for force/position actuation generally includes an electric linear actuator and a controller. The controller interfaces with the electric linear actuator and with a number of I/O signals that are independent from the electric linear actuator. The controller interface to the independent I/O signals is transparent to the manner in which the I/O signals are produced. Rather the controller simply looks for the status of the I/O that is preferably received into the controller by hard-wiring or field bus I/O messaging such as from a industrial robot or programmable logic controller. The adaptable servo-control system is particularly suited to resistance weld systems wherein the electric linear actuator can replace the pneumatic actuator providing position and force actuation of the weld tip of the welding gun.

摘要： An apparatus for contacting and applying a force to opposite sides of a workpiece, such as a resistance welding device adapted for use on an automated assembly line. The apparatus is configured to be extremely rigid to ensure accurate movement and positioning of a pair of contacts with respect to a workpiece. The apparatus includes a frame member supported by a base with first and second shafts that are secured to the frame member and slidably supported by the base. The second shaft prevents rotation of the frame member about the first shaft during operation of the apparatus. The frame member carries one of the contacts, and is biased away from the workpiece and toward a second position nearer the workpiece. An extendable member and a link are both pivotably mounted to the frame member, and support an anvil carrying the remaining contact. The link is engaged with the base when the link is in a first rotational position, at which point the second contact is held away from the workpiece by the anvil. The link disengages the base when the link rotates to a second rotational position, at which point the second contact is lowered adjacent the workpiece by the anvil. When engaged with the base, the link overcomes the biasing force applied to the frame member and forces the frame member away from the workpiece. When the link is disengaged from the base, the frame member is biased toward the workpiece.

摘要： An electrode for electric resistance welding comprises a guide hole of a circular cross-section composed of a small-diameter hole and a large-diameter hole, a guide pin composed of a small-diameter portion and a large-diameter portion, the small-diameter portion and larger-diameter portion of the guide pin being fitted into the small-diameter hole and large-diameter hole of the guide hole, respectively, so that when the guide pin is pushed down, compressed air is allowed to jet out of a gap between the small-diameter hole and the small-diameter portion. The large-diameter portion of the guide pin is firmly fitted into the guide hole, with an air passage formed in the outer circumference of the large-diameter portion and the end surface of the large-diameter portion seated on the inner end surface of the large-diameter hole.

摘要： A copper core weld gun assembly is provided with a substantially omega (.OMEGA.) shaped cross-section taken through each arm of the assembly. Concentric copper tubes are provided to carry cooling water and electric current to the electrodes of each arm. Special fittings are provided to insure that cooling water is carried directly to and from the electrodes without contacting the body, thereby eliminating galvanization in aluminum bodies. The design includes wedge-shaped barrel locks, crown-tipped incoming water tubes, thimble-shaped female electrode caps, and provides modular design capability. A modular gun design separates the gun into three fundamental areas: (a) the electrode system; (b) the body/frame system; and (c) the moment arm design.

摘要： A fusing electrode is mounted on a vertically movable carriage which is raised by a first air actuator and lowered by gravity into engagement with a commutator tang. During a fusing cycle, different pressures are applied between the fusing electrode and the tang by means of a fast-acting air actuator that has a downwardly-extending piston rod engageable with the carriage and which is controlled by a programmable pressure regulating valve. To increase the response time and the force follow through of the second air actuator, the programmable pressure regulating valve is mounted directly on top of the second air actuator with its air outlet located as close to the cylinder of the second actuator as permitted by the air fittings which connect them. Surge tanks associated with the programmable valve assist in ensuring speedy response times.

摘要： A fast response weld head which employs a control system to allow user control of critical welding parameters such as speed, force, position, and duration. In one embodiment, the control system includes a position servo loop attached to a motor driven output shaft on which a welding electrode is mounted utilizing a follow-up spring assembly. During a weld cycle, the control system moves the welding electrode toward a workpiece at a rapid user-defined rate. Just prior to when the electrode is reduced to prevent damage to the parts. When contact is made, the force exerted by the electrode on the workpiece is measured until the measured force equals a user-defined optimum welding force. A user-defined weld current is enabled to the electrode. When the weld is complete, the welding electrode is automatically raised by the control system, releasing all pressure on the workpiece. In a second and presently preferred embodiment, a linear magnetic actuator is utilized in lieu of a motor to drive the output shaft. The follow-up spring assembly is eliminated. The force required to keep constant pressure on the weld is now provided by programming the linear actuator to exert a very short pulse of force to maintain constant pressure on the weld as the weld softens at the onset of applications of weld current. Force is then returned to normal force until the weld is complete.
