A shaft precision automatic measurement device (1) for a motor (9) includes: a gripping mechanism (3) that grips the shaft (7); a first contact-type displacement sensor (41) that is able to measure a position of the flange face (82) by contacting to follow the flange face (82); a second contact-type displacement sensor (42) that is able to measure a position of the fitting face (81) by contacting to follow the fitting face (81); a rotary mechanism (5) that causes the device main body (2) to rotate in a state gripping the shaft (7) by the gripping mechanism (3) and executing measurement by way of the respective displacement sensors; a displacement data acquisition part (63) that acquires displacement data of the flange face (82) and displacement data of the fitting face (81); and a measurement part (64) that measures center runout and face deflection of the shaft (7) based on the respective displacement data acquired by the displacement data acquisition part (63).

Embodiments provide measurement systems having a coordinate measuring machine, a workpiece storage apparatus, and a robot for delivering workpieces from the workpiece storage apparatus to the coordinate measuring machine, and methods for orienting and operating such systems. Illustrative embodiments employ a reference geometry tool on the robotic arm, and kinematic locators on the coordinate measuring machine and/or on the workpiece storage apparatus to define a coordinate system common to the coordinate measuring machine, the workpiece storage apparatus, and the robot.

A modular kinematic and telemetry system for an irrigation system includes a condition-based monitoring (CBM) system and a plurality of sets of modular foot assemblies. The CBM system has a housing and supports a plurality of kinematic and telemetry components. The plurality of sets of modular foot assemblies includes a first set and a second set that secure to the housing of the CBM system. The first set is configured to secure the CBM system to a first end gun configuration and the second set is configured to secure the CBM system to a second end gun configuration that is different from the first end gun configuration.

The three-dimensional measuring method includes: a conveying step of conveying a workpiece to be measured by a robot arm configured to change an attitude of the workpiece; a measuring step of performing three-dimensional measurement on the workpiece by a probe configured to be movable relative to the surface plate in a state in which the workpiece is held by the robot arm; a relative-position change detecting step of detecting a change in a relative position between the surface plate and the robot arm; and a vibration correcting step of correcting a result of the measurement performed on the workpiece in the measuring step based on a result of detection performed in the relative-position change detecting step.

The sensor adaptor includes a case body of which a front end is closed and a rear end is open, a cap body being engageable with the rear end of the case body, a seal member interposed between the case body and the cap body, and a fixing portion configured to fix the case body to the mounting portion. A part of the sensor is inserted into an accommodation space of the case body, and the remaining portion of the sensor is drawn out to the outside via an opening of the cap body. The seal member is disposed on a rear end side of the case body to surround the sensor. The seal member is brought into close contact with the case body and the sensor. Accordingly, a gap between the part of the sensor and the case body is sealed from an external space by the seal member.
