Abstract

본 발명은 자동차 크랭크 샤프트의 단차거리 측정장치에 관한 것으로서, 베이스(2) 상단의 고정대(6)와 이동대(10)에 크랭크 샤프트(8)의 양단을 지지시킨 후 미리 중앙 메인저널(12) 가공부의 기준측면(14)이 이루어야할 설계상의 단차거리(A)로 고정되어 있는 바(4)를 상기 메인저널(12)의 가공부에 진입시켜 보아 가공된 크랭크 샤프트(8)의 단차거리(A)와 설계상의 단차거리를 비교측정하는 자동차 크랭크 샤프트의 단차거리 측정장치에 있어서, 상기 바(4)의 선단에 힌지핀(22)을 통하여 회동가능하게 유설되는 절곡된 회동편(24)과, 상기 회동편(24)의 일단이 상기 메인저널(12)의 기준측면(14)에 항상 접촉하는 탄발력을 제공하도록 상기 바(4)와 상기 회동편(24)에 양단이 연결된 탄성부재(26)와, 상기 회동편(24)의 타단에 그 측정자가 접촉하도록 상기 바(4)의 일측에 고정되는 다이얼 게이지(20)를 포함하여 크랭크 샤프트(8) 가공부의 기준측면(14)을 정확하게 항시 측정하게 되므로 종래와 같이 바(4)와 기준측면(14) 사이의 틈새가 배제되므로 더욱 정확한 측정을 가능하게 함으로써, 후공정에서의 치수관리에 정확성을 기할 수 있고, 결국 크랭크 샤프트(8)의 불량률을 감소시키고 품질을 향상시키는 효과가 있다.The present invention relates to an apparatus for measuring a step distance of an automobile crankshaft, and after supporting both ends of the crankshaft (8) on the fixed base (6) and the movable base (10) at the top of the base (2), the central main journal (12) in advance. The step distance of the crankshaft 8 which is processed by entering the bar 4 fixed to the design step distance A to be made by the reference side 14 of the machining part into the machining part of the main journal 12 ( An apparatus for measuring a step distance of an automotive crankshaft for comparing and measuring step A) and a design step distance, comprising: a bent rotation piece 24 rotatably disposed at a tip of the bar 4 via a hinge pin 22; An elastic member having both ends connected to the bar 4 and the pivoting piece 24 such that one end of the pivoting piece 24 always provides a resilient force in contact with the reference side surface 14 of the main journal 12; 26) and one side of the bar 4 so that the measurer contacts the other end of the pivoting piece 24. Since the reference side 14 of the crankshaft 8 machining portion is accurately measured at all times, including the dial gauge 20 fixed to it, the gap between the bar 4 and the reference side 14 is excluded as in the related art. By enabling the measurement, it is possible to ensure accuracy in the dimensional control in the post process, which in turn has the effect of reducing the defective rate of the crankshaft 8 and improving the quality.
