摘要:
A threaded shaft measuring device includes a table that supports a threaded shaft to be measured, and that is capable of adjusting a rotation position about a perpendicular Z axis, adjusting a rotation position about an X axis that is horizontal and intersects with the Z axis, and adjusting a position in a Y axis direction that is horizontal and intersects with the X axis; and a stylus that performs scanning measurement of a surface of the threaded shaft. An adjustment jig capable of making contact with the threaded shaft and an elevator that brings the adjustment jig into contact with the threaded shaft are installed on the table. The adjustment jig includes an abutting bottom surface; an abutting side surface; a measurement surface; and an axis line marker that enables a tilt relative to the X axis to be detected.

A thread gauge inspection apparatus includes a receiving member to hold a reference thread gauge and a motor to bi-directionally rotate the reference thread gauge. A counter counts a number of turns the reference thread gauge is rotated by the motor, and a torque monitoring device monitors the torque produced by the motor as the reference thread gauge is rotated. A controller, when the monitored torque exceeds a predetermined value, causes the motor to stop rotating the reference thread gauge and causes the counter to stop counting the number of turns the reference thread gauge is rotated. The controller compares the count produced by the counter with an inputted specific turn count and indicates the thread quality of threaded hole or a threaded stud passed inspection when the count produced by the counter is equal to the inputted specific turn count.

Controller executes a first scanning control, causing a driver to move a probe such that a tip scans along an inclined surface of a V groove to approach a center of the V groove, and a second scanning control, causing the driver to move the probe such that the tip scans along the inclined surface of the V groove to approach the center of the V groove from a side opposite that of the first scanning control. Angle calculator calculates an angle created between a direction of a deflection vector of the probe and a predetermined direction. Threshold value-correspondent coordinate obtainer obtains coordinates of the tip where the angle has changed to exceed a first threshold value during execution of the first scanning control and obtains coordinates of the tip where the angle has changed to exceed a second threshold value during execution of the second scanning control.

A thread gauge, which allows to reliably know the time for replacement by visual checking and improves the predetermined dimensional accuracy of a thread product has a go-side thread measuring portion extending from one side of a shank portion coaxially with the shank portion or a not-go-side thread measuring portion extending from an other side of the shank portion coaxially with the shank portion, a wear checking gauge line having a predetermined length and a predetermined depth formed on male thread portions and female thread portions formed on the go-side thread measuring portion or the not-go-side thread measuring portion.

摘要:
A gauging device and method for use in coupling threaded tubular articles including tubes and couplings. The device and method provides for the use of gauges for the tube and coupling that provide markings thereon that when in register during coupling indicate when a preselected threading distance has been achieved. A coupling assembly is provided that employs an annular gasket attached to the coupling and adapted to be deformed by the end of a tube when inserted into the coupling to provide sealing.

A workpiece gaging system includes carriage structure for a gaging part, movable longitudinally and laterally, and a rotor to rotate that structure; also indicator means is operatively connected with the part to indicate the status of engagement, displacement, or need for displacement, of the gaging part relative to a surface or surfaces (such as pipe threads) to be gaged, as at multiple locations. Measurement encoding and signal processing means are also provided.
