摘要： A precision positioning system is used for resurfacing and repairing rails and guideways of large, heavy machinery at users facilities. The system has new components, an entire machining system, a new alignment system, parallel platforms for tool support and surface scanning. A sectioned, portable monorail frame is held by fixed supports at the locus of a heavy machine requiring guideway straightening. Fixed guides extend along the outer surface of the monorail. Guide wheels and drive wheels contact the guides and support and move an outer tubular beam carriage. An assembly of machining tools is adjustably positioned on the carriage. Laser alignment sources and sensors are connected to the carriage and to heavy machines off-axis and parallel to the monorail. Intelligent controls precisely position the tools for resurfacing the rails and guideways. Scanning and a printout of machine guideway accuracy, before and after the operation, provide written verification of quality improvement. The system increases accuracy and speed of machining, reduces chatter and vibration, eliminates imprecise manual determinations, and returns the equipment to acceptable improved tolerances. The system has applications in any machine tool rebuilder or company with a machine tool in need of requalification. Applications also include rail transport, autonomous vehicles, micro-machining, inspection camera positioning, laser machining, material deposition and other operations such as drilling, heat treating, brazing and welding.

摘要： A laser-based multi-axis position measurement unit measures position deviations in 5 axes while traversing a 6th linear axis. The apparatus includes three components: 1) a laser-beam unit which emits two parallel laser beams; 2) a sensor unit including at least three laser-position sensors, one of them being transparent; and 3) a microprocessor or computer unit which converts X,Y laser position data from the three sensors to displacements in 5 axes: X (horizontal), Y (vertical), Pitch (angular motion about the X axis), Yaw (angular motion about the Y axis), and Roll (angular motion about the line of travel). Readout of the 6th axis, the line of travel, is provided by means of a separate linear transducer or laser-based ranging system. The device includes an arrangement of three digital sensors on two parallel laser beams to deduce position in 5 axes. Applications for the measurement unit exist in machine tool measurement and calibration, robotics, coordinate measurement machines, optical alignment and other areas where position in multiple axes must be determined. The position information may be directly displayed or used as input for a closed-loop positioning system.
