The present invention relates to a system and its control method for press-fit equipment for shaft-hole fit parts. The automatic press-fit control system mainly includes a control center, a loading and unloading control subsystem, a visual inspection subsystem, and a press-fit control subsystem, and each subsystem communicates with the control center through a communication interface. The control center automates the operation of each subsystem independently, such as the product loading and unloading process, the visual inspection process, and the press-fit process through the control center. The advantages of the invention are: it can realize automatic loading, inspection, and press-fit of the product, which greatly improves the level of production automation and production efficiency; the control system adopts modular design, and each subsystem can operate independently under the control of the control center; it adopts visual inspection and automatic compensation of angle deviation, with good fault tolerance.

An insert including a taper is covered with a molten metal. A metal molded product with the insert joined thereto is generated by semi-cooling the molten metal to a press-fitting temperature which is higher than a recrystallization temperature of the molten metal and lower than a melting point of the molten metal. A fitting hole which is filled with the insert is formed in the metal molded product. The taper is fitted into the fitting hole. An undercut is not formed in front of a tip of the taper. The insert is press-fitted into the fitting hole while pressing and extending the fitting hole with the taper in a thinning direction of the taper at a press-fitting temperature. The metal molded product is further cooled with the press-fitting maintained.

To provide a fuel nozzle for a gas turbine combustor, offering favorable durability and strength reliability. In a fuel nozzle for a gas turbine combustor, jetting fuel into a combustion chamber of the gas turbine combustor, the fuel nozzle is metallurgically and integrally bonded with a base plate that supports the fuel nozzle, and an interface between the fuel nozzle and the base plate includes a surface in which bonding is performed by a fusion joint or a brazing joint and an inside part in which bonding is performed by pressure bonding.

A feeding and fastening device for a coin-shaped fastener and comprising: a punch tool; a feeding device configured to feed the fastener one at a time; a hollow pillar-shaped portion below the punch tool; a holding portion to temporarily hold the fastener fed though a side surface thereof and to release the fastener when the punch tool pushes down on that fastener; a part passage route portion below the holding portion for guiding the fastener downward in a vertical orientation by means of a cross section with a width that prevents inversion; a guide portion below the passage route portion guides the fastener from the vertical orientation to a horizontal orientation; and a fastening portion below the guide portion receives the fastener in the vertical orientation and locates the fastener above the workpiece until struck by the punch tool.

A puller includes a first claw and a second claw arranged opposite to each other. The first claw includes a first pulling part, a first limiting part and a first connecting part. The first limiting part includes a first body part, a first notch part and a second notch part. The second claw includes a second pulling part, a second limiting part and a second connecting part. The second limiting part includes a second body part, a third notch part and a fourth notch part. A size of the second pulling part is smaller than or equal to a size of the second notch part.

The present technology generally relates to devices, systems and methods for providing robust sealing between surfaces in a pressurized system, such as a chromatography system. In particular, the devices, systems and methods relate to compliant and resilient parts that can be reused and/or reinstalled while providing a pressure tight sealing surface even within a high pressure environment (e.g., 1000 psi or greater).

A system for removing and replacing fire-tubes. The system can include a powered system, a fire-tube puller coupled to said powered system. The fire-tube puller has a puller back which is coupled to a plug rest. A plug rest is approximately perpendicular to the puller back, and the fire-tube will rest upon the plug rest when the fire-tube is being removed or installed. The system can also include a stack adjuster which is coupled to the plug rest. The stack adjuster can couple to a stack so as to reposition the stack.
