Abstract: 380-78-0140 COORDINATE MEASURING MACHINE HAVING LOW FRICTION CURTAINS TO PROTECT THE WAY SURFACES A coordinate measuring machine in which a low friction curtain protects ways and the measuring gratings from debris, damage and resulting measurement inaccuracies. The low friction is obtained by supporting the curtain on a fluid film at its mounting to a support carried by the base. Advantageously, the machine includes a horizontally moving carriage moves along horizontal ways on a base and the base includes a support at the ends of the ways. Curtains made of flexible material are attached to the carriage and extend over the supports. The support is preferably coupled to a source of fluid under pressure, which source is coupled to provide a fluid film between the curtain and the support.

Abstract: A coordinate measuring machine for measuring parts using cylindrical coordinates. The machine includes a base, an articulated arm mounted to the base at its proximate end for movement within a plane, and a vertically movable probe assembly mounted near the distal end of the articulated arm. A horizontal measuring rod extends between the distal end of the arm and the base to provide a measurement of the location of the probe with respect to the base, in terms of a radius and an angular displacement. The probe assembly includes means for measuring perpendicular displacement of the probe from the plane of the articulated arm.

Abstract: A linear motion mechanism is disclosed consisting of an output member comprising a slide block mounted for sliding linear movement on a slide frame, which slide frame is in turn detachably secured to a vertical drive assembly including a mounting frame having a vertically extending mounting surface formed thereon. The slide block is drivingly connected to a motion amplifying mechanism carried on the mounting frame including an input push link on which is rotatably mounted a rotary drive element engaged with a drive chain fixed at one end and connected at the other end to the slide block so that the motion of the slide block is an amplification of the motion of the push link in direction away from the chain ends. The push link is translated by a rotary cam and pivoted lever pinned to one end of the push link. The slide block and slide frame are adapted for use separately from the mounting frame and motion amplification mechanism by mounting it on a horizontal surface and directly engaging the slide block with a rotary cam.

Abstract: 380-78-0030 COORINATE MEASURING MACHINE HAVING A FAILSAFE PROTECTION SYSTEM A coordinate measuring machine having an automatic failsafe protection system. The coordinate measuring machine includes a vertically mounted probe shaft which is preferably counterbalanced by an air counterbalance system. The automatic failsafe protection system insures that, in response to a loss of air pressure (or in response to other possibly unsafe conditions), the vertically-mounted, air-counterbalanced probe shaft will be prevented from falling down uncontrollably. The failsafe protection system includes a pair of members, with each member mounted adjacent to and on opposite sides of the probe shaft and urged toward engagement with probe shaft by a spring. Air under pressure from an air cylinder also acts upon the members to bias the members outwardly away from engagement with the shaft when normal(i.e. safe) operating conditions exist. An unsafe operating condition causes a decrease in air pressure from the cylinder which allows the spring to bias the members into contact with the probe shaft to brake its descent by progressively engaging the shaft. Additional springs also urge the members into contact with the probe shaft in response to an unsafe condition. The present invention overcomes the limitations and undesirable features of the prior art devices while providing a failsafe system which is relatively reliable and inexpensive, while not interfering with the functioning of a coordinate measuring machine in normal operation.

Abstract: 380-78-0020 COORDINATE MEASURING MACHINE HAVING AN AIR COUNTERBALANCE A coordinate measuring machine having a vertically mounted probe and a reduced-friction pneumatic counterbalance for the probe, with the counterbalance coupled to the probe through a torque converter to allow a shorter travel length of the counterbalance compared with a longer travel of the vertical probe. The torque converter is coupled to the counterbalance and the probe by low friction metallic tapes in its preferred embodiment.

Abstract: COORDINATE MEASURING MACHINE HAVING AUXILIARY AIR BEARING An auxiliar air bearing system (50) for reducing friction in mechanical bearings (41, 42) to improve repeatability of measurements on a coordinate measuring machine (10). The air bearing system (50) and mechanical bearings (41, 42, 43) support a moveable carriage (30) on a base (20). The air bearing system (50) comprises an air pad assembly (70) mounted to the carriage (30), an air system (80) supplying air under pressure and a rail system (60) mounted to the base (20) with the air pad (70) including a compressed spring (76) captivated therein. Air under pressure is directed between the air pad assembly (70) and the rail system (60), causing the air pad assembly (70) to lift from the rail system (60) and the base (20). The air bearing system (50) and the spring (76) reduce the effect of any irregularities on the rail that would otherwise cause measurement errors. The air bearing system (50) is preferably mounted obliquely to two of the mechanical bearings (41, 42) so that a single air bearing assembly reduces the friction in the mechanical bearings supporting the carriage in two directions.

Abstract: A coordinate measuring machine (10) having a vertically mounted probe (32), the weight of which is offset by an air counterbalance system (100). The air counterbalance system is adapted to use a source of air under pressure acting upon a piston (127) coupled to the vertically mounted probe (42). A torque converter (130) is mounted between the probe (42) and the piston (127) allowing the piston (127) to have a shorter travel than the allowable vertical travel of the probe (42). The air counterbalance system (100) preferably has components selected and arranged to minimize friction and weight to avoid distorting the precision of measurements on the coordinate measurement machine.
