An Online Measurement System for the Radial and Face Runouts of Axle Gears Based on LabVIEW

An online automatic measurement system for the measurement of radial and face runouts of axle gears is presented, which consists of mechanism and control system. According to the measuring principle, the mechanism can automatically implement measurement procedure including up and down the axle gear and preliminary positioning of the measured workpiece, detection, striking out. Movement procedure control is accomplished by a PLC, while runout measurement and data processing are done by industrial personal computer （IPC）. Based on virtual instrument technique, the software has been programmed based on LabVIEW. Experimental results show that the measuring accuracy of the system is ±3μm, and its efficiency is 10 s/set. The developed system, with higher accuracy and speediness and also without operator, can satisfy the requirement of the radial and face runout automatic measurement in the automatic assembly-line for the axle gear.
