Systems and methods are provided for aligning a fastener feed mechanism. One embodiment is an apparatus that includes an alignment tool that aligns a fastener feed mechanism with a chamber of a fastening device that receives fasteners. The alignment tool includes a tip section having a diameter less than a diameter of the chamber, a chamber fit section that extends from an end of the tip section in a lengthwise direction and has a diameter corresponding with the diameter of the chamber, a lip that protrudes radially from the chamber beyond the diameter of the chamber, and a fitting member that extends from the lip in the lengthwise direction.

A checking fixture for a steering knuckle. In use, a workpiece is mounted on the checking fixture, three locating points of the workpiece in the X direction respectively correspond to a supporting pin I, a supporting pin II and a supporting pin III, a locating taper hole limiting the motion of the workpiece in a YZ plane corresponds to the floating pin, and a locating point of the workpiece in the Y direction levelly fit to a supporting surface of a locating pin; after location is completed, the workpiece is tightly clamped by a jacking clamp, a press clamp I and a press clamp II. The checking fixture for the steering knuckle can measure the position accuracy of each hole of the steering knuckle workpiece, and can detect whether the relative height of the flange plane of the workpiece relative to the X-direction locating points is qualified.

Mounting apparatuses for turbine airfoils of turbine systems are disclosed. The mounting apparatuses may include a body portion configured to be at least partially positioned between a first airfoil and a second airfoil of the turbine system, and an adjustable, first retention component formed on a first side of the body portion. The adjustable, first retention component may be configured to contact a portion of a suction side of the first airfoil of the turbine system. The mounting apparatuses may also include a second retention component formed on a second side of the body portion, opposite the first side. The second retention component may be configured to contact a portion of a pressure side of the second airfoil of the turbine system.

A straightness checking method includes the steps of standing a pin at each of both edge portions of linear members of a plurality of linearly-disposed components, and also standing a cut-out pin formed to have a cut-out on a part of a side face thereof, at an intermediate portion between the both edge portions, fixing one end portion and the other end portion of a line member respectively to the pins stood at the both edge portions, bringing into contact with the intermediate portion of the line member an uncut side face part corresponding to a side face without the cut-out formed of the cut-out pin, and rotating the cut-out pin and checking whether or not the line member vibrates due to rotation of the cut-out pin.
