DEVICE FOR CHECKING PARAMETERS OF HOLE KEY WAY

摘要

measurement technology. SUBSTANCE: proposed device is designed for measuring width of key way and its deflection from hole axis. Device has housing 1 with alignment pins 2, 3, indication unit 6, feeler gauge 5 rigidly coupled with rod 4 installed in housing 1. Article to be checked is located in housing 1 by pacing its hole on alignment pins 2, 3 with provision of contact of feeler gauge 5 with surface 8 of slot to be checked. EFFECT: improved accuracy of me checking. 2 dwg
