Description

Technical Field

[0001] This utility model relates to the field of centerless mill testing technology, and in particular to a precision testing device for centerless mills. Background Technology

[0002] A centerless grinder consists of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece support. The grinding wheel performs the actual grinding work, the adjusting wheel controls the workpiece's rotation and provides the feed speed, and the workpiece support supports the workpiece during grinding. It has two grinding wheels: a guide wheel and a grinding wheel. The guide wheel rotates the cylindrical workpiece on a support, while the grinding wheel performs the grinding action.

[0003] After the workpiece is processed, it needs to be inspected. Currently, centerless grinding workpieces are usually inspected using a laser measuring instrument. During inspection, the measuring instrument needs to be moved frequently to inspect various positions of the workpiece. However, the laser measuring instrument is not easy to move, and the inspection efficiency is low. Moreover, the existing inspection device does not have a clamping device for the workpiece, and the workpiece is prone to displacement during the inspection process, which affects the accuracy of the inspection results.
