July 18th, 2009 | by Ramaswami |Tooth aligning device for the aligning of workpiece with pre-cut teeth on gear finishing machines
The invention concerns a device for the non-contact measurement of the position of the teeth (13) of a workpiece (14) with precut teeth on a gear finishing machine. The measuring probe, retractable from the measuring position into a position of rest protected against soiling, is arranged in a holder (5) for radial and axial adjustment relative to the workpiece, the said holder (5) being a kinematic member of a parallelogram linkage (A) and by means of a hydraulic, pneumatic or electromechanical swivel drive (11) is swivellable from stop to stop between measuring position and position of rest in a plane containing the workpiece axis, such that in the advancement action from the lower end position to the top end position motions of the measuring probe (1) tangential to the workpiece circumference are completely avoided. The parallelogram kinematics moreover afford adequate protection against swarf and grinding dust, and lends the device a high stiffness and reliability.
Devices for the ultrasonic testing of a workpiece by the transmission technique
A device for the free-jet ultrasonic testing of a workpiece by the transmission technique includes a first test head, serving as an ultrasound transmitter, and a second test head, serving as an ultrasound receiver. The test heads are respectively disposed on a first robot and a second robot, in each case in a freely movable manner, with at least one degree of freedom, such that they are aligned coaxially in relation to each other and perpendicular to a surface of a workpiece. The robots are positioned such that they are fixed in place on a displaceable common carrier.
Gas main robotic inspection system
The present invention provides a long-range, untethered, live, in-pipe inspection system that includes a self-propelled train having a plurality of modules; joint members for interconnecting adjacent modules, data collection components, and wireless communication components for transmitting collected data and receiving control messages. The module-train includes, generally, at least one, and preferably two drive modules, at least one power module and an electronics module. The train may additionally include at least one support module, which may be interposed between the power and electronics modules. In one embodiment of the invention, there are two drive modules, one at each terminal end of the train, two power modules, one adjacent to each drive module, two support modules, one adjacent to each power module, and one central electronics and computing module.
Apparatus and method for non-destructive inspection of large structures
An automated inspection system and method enables rapid, remote and non-contact inspection of large objects, utilizing non-destructive inspection techniques, that does not require continuous manual repositioning of the inspection equipment. The inspection system includes a remote controlled robotic vehicle including a sensor package capable of non-destructive inspection of a structure and a mechanism for locating the sensor package at a plurality of inspection sights on the structure; a positioning system for determining the location of the robotic vehicle with respect to the structure to be inspected; a control system for controlling the movement of the robotic vehicle around the structure to be inspected; and an analysis systems for analyzing data generated by the sensor platform.
Method and apparatus for monitoring the operation of a wafer handling robot
The integrity of control signals used to control a wafer handling robot is monitored by a monitor connected to various points of the robotic control system. The monitor includes a memory for storing data sets representing correct, reference characteristics of the control signals. The monitor samples control signals at various points in the control system and compares these sampled signals with the stored reference characteristics in order to determine whether a signal disparity exists. If a disparity exists, the monitor generates an error.
