The present invention discloses an inspection tool for surface of paint that is capable of detecting if a diameter of the minimum surface without paint of a mounting surface of a bolt hole is qualified, and if a height of surface without paint of side wall of a bolt hole as a counter hole exceeds a given range. The present invention is of simple structure and is convenient for use.

In the straightening of radial run-out faults or linearity faults on elongate workpieces having at least one toothed region having peaks and troughs of the teeth of said toothed region, such as on toothed shafts or toothed racks, for ascertaining deviations from the ideally straight workpiece, the locations of the surfaces of the not yet straightened workpiece that form a reference plane are scanned at least at points or in portions on or in the region on the active reference circle or pitch circle, respectively, of the toothing that lies between the peaks and troughs of the teeth. The resulting measured items of data are utilized by the straightening machine such that a workpiece that is as ideally straight as possible at least in the toothed region is achieved by the straightening. The elevated locations of the tooth heads of the toothed region that form the peaks of the teeth and the elevated locations of neighboring tooth surfaces that lie in the reference plane are detected, and the height differentials of the elevated locations of the tooth heads in relation to the elevated locations of neighboring tooth surfaces that lie in the reference plane are ascertained. The height differentials are utilized by the straightening machine as corrective measured items of data such that said height differentials are considered when straightening the workpiece so as to form a workpiece that is as ideally straight as possible in the reference plane.

A measuring apparatus for measuring an occlusal distance and/or a space of a missing tooth comprises a connecting rod and a measuring head disposed at an upper end of the connecting rod, the measuring head comprises a first measuring ruler and a second measuring ruler perpendicular to the first measuring ruler, a lower end of the second measuring ruler and one end of the first measuring ruler are connected to the connecting rod. The occlusal distance checking can be performed simply and directly by using the first measuring ruler to directly compare whether it can pass through the occlusion gap in the region to be repaired, the gap of the single missing tooth analysis is performed easily and directly by using the second measuring ruler to directly compare whether it can pass the gap in the measuring region to be repaired.

A gauge comprising an elongate rod and a head. The rod has an elongate axis. The head has a transverse dimension perpendicular to the elongate axis of the rod. The gauge has an insertion configuration and an inspection configuration, wherein the transverse dimension of the head is greater in the inspection configuration than in the insertion configuration. The head comprises two head portions each with a longitudinally-extending outer surface and a longitudinally-extending inner surface and, in the insertion configuration, the inner surfaces of the head portions are at least partly in abutment with each other. The gauge can be used in a method of measuring an internal dimension of a bore within a component.

A countersink go/no-go gauge is configured to aid a determination of whether a countersink aperture for a rivet is formed to a desired depth. The countersink go/no-go gauge includes a head having a depth defined between a top surface and a bottom surface and a shaft extending from the top surface of the head. The depth of the head is substantially equal to a desired depth of a countersink aperture. In some embodiments the go/no-go gauge includes tolerance features to provide a range for an acceptable countersink depth.

A floating drift apparatus for verifying the inner diameter of tubulars as the tubulars are made up into a tubular string being run into a wellbore. A float section provides buoyancy to float the apparatus in fluid within the bore of a tubular, and a drift section has a drift element with a diameter substantially equal to the tubular inner diameter being verified, which may be the drift diameter. When running a tubular string, the apparatus is inserted into the bore of the tubular string, floating in the fluid. As joints of tubular are made up and run into the wellbore, the tubulars move downhole around the apparatus. Preferably, the floating drift apparatus can be visually detected. If an undersize ID is encountered, the floating drift apparatus will be pushed downhole and no longer visible; the operator can remove the undersize ID tubular from the string.
