PRECISION MEASURING SYSTEM FOR THE CRANK SHAFT OF AUTOMOTIVE ENGINE

摘要

PURPOSE: A precise measurement system for a crank shaft in a vehicle is provided to remove shaking error due to the unnecessary operation of a measuring sensor by measuring the machining accuracy of a crank shaft. CONSTITUTION: A precise measurement system for a crank shaft in a vehicle comprises a rotary arm(301), a driving part(302) and a stocking part(303). The measurement system comprises a horizontal maintaining part(304). The driving part drives the rotary arm. The stocking part is arranged at the front end of the rotary arm. The stocking part stocks the crank shaft according to the circulation of the rotary arm. The horizontal maintaining part maintains the horizontality in order to prevent the crank shaft from being separated.
