Abstract
A bore dial indicator and dial gage for a quick adjusting measuring head can quickly adjust and change an adjustable measuring head. The utility model is divided into A type and B type characterized in that scales and numbers with each graduation of 1mm are engraved on the adjustable measuring head along the axial surface, the adjustable measuring head and the connection member are clearance fit and screw fixation; a counter window of the B type meter is arranged on the connection member of the adjustable measuring head, and differential scales and numbers are engraved under the window. Besides the characteristics in the shape and the structure showed above, others are equal to the prior known bore dial indicator and dial gage. The bore dial indicator and dial gage of the utility model is unique and practical, when the operator uses, the time for proofreading scale is greatly reduced, and the work efficiency is improved.
Description
Affiliated technical field
