摘要： An adjustable guide, includes two or more mechanisms each having a rotatable retaining element containing a retaining groove with a variable radius in its perimeter surface. The grooves form a guidance path to control the lateral, i.e. non-axial, motion of a long bar moving along a longitudinal axis during a production process.The diameter of the guidance path varies according to the variable radii of the grooves. The guidance path increases in size at a predetermined rate, from a point of origin to an end point on the retaining groove. Rotating the retaining elements causes the diameter of the retaining grooves to change so that the size of the guidance path can be changed to match the diameter of the bar being rolled, size of the guidance path can be changed to fit the diameter of a new bar rolled without having to exchange the guide for a different sized guide, reduce fiction between the bar and the guide, a media, such as compressed air, can be injected between the retaining elements via orifices.Each retaining element is attached to a mounting apparatus. The mounting apparatus can be fixed or flexible. The flexible mounting apparatus includes one or more springs and one or more shock absorbers. A force neutral position of the flexible mounting apparatus is designed to be located on the predetermined ideal bar path line. The flexible mounting apparatus dissipates kinetic energy from the bar thereby reducing the bar's lateral motion relative to the ideal bar path line.The damping ratio of the mounting apparatus can be adjustable to alter the product's vibration mode to enable better control of the bar's lateral motion.

摘要： An inspection system for detecting flaws on a moving metal (e.g., steel) bar coordinates the operation of an eddy current testing (ECT)-based flaw detection apparatus and an imaging-based flaw detection apparatus. The ECT-based flaw detection apparatus and the imaging-based flaw detection apparatus are disposed along a movement path in a predetermined relationship with each other, for example, as a predetermined fixed offset distance therebetween. A synchronizing mechanism synchronizes the output data streams from the two flaw detection apparatuses based on the predetermined relationship, so as to align the data streams as function of the axial position on the metal bar. A processing unit is configured to process the synchronized data streams for the detection of flaws, which are then also synchronized (axial position). The synchronization permits a variety of cross-referencing operations, such a flaw verification as to the existence of flaws, as well augmenting imaging-based flaws with flaw depth information from the ECT-based apparatus.

摘要： An apparatus to control lateral motion of a bar moving along a guidance path includes a pair of rotatable hubs each having at least first and second rollers at locations around the perimeter of the hub. The first roller has a first retaining groove of a first radius and the second roller has a second groove of a second radius smaller than the first radius. Each hub further includes at least one guiding element located between the rollers with a guide channel extending in the outer surface. A mounting system allows the hubs to be rotated between first and second positions. In the first position the first rollers oppose each other forming a guideway having a first, enlarged diameter for capturing a free end of an approaching bar. In the second position the second rollers form a second, smaller diameter to match the actual size of the bar.

摘要： An inspection system is used to view an image of the inside diameter (ID) of an engine bearing. The inspection system includes a stationary line scan camera, a pivoting mirror, a scanning mirror and a stationary mount. The engine bearing is placed in the stationary mount such that the bearing remains motionless throughout the entire scanning process. The light line generator produces a light line that initially contacts a beam splitter. The beam splitter then guides the light line onto the pivoting mirror, which then directs the light line onto one of a pair of stationary mirrors and then finally onto the scanning mirror. The scanning mirror will sweep the light line across a portion of the engine bearing ID surface. The light line will generate reflected images of the ID surface. These reflected images will return along the light line's path; however, instead of being directed back into the light line generator by the beam splitter, the reflected images will pass through the beam splitter. Once the reflected images pass through the beam splitter, they will journey through the lens and into the stationary line scan camera. From the stationary line camera, the reflected images can be viewed on a monitor and recorded for future use.
