Flywheel shell vibration detection tool

Abstract

The invention discloses a flywheel shell vibration detection tool. The flywheel shell vibration detection tool comprises a main frame body, a rotating block, a fixed bracket and a positioning disc, wherein a bearing sleeve is arranged on the top of the main frame body, a rotating shaft is assembled in the bearing sleeve, and one end of the rotating block is fixedly in butt joint with the outer endof the rotating shaft; the other end of the rotating block is fixedly in butt joint with a bearing, and the positioning disc sleeves the bearing; one end of the fixed bracket is fixed to the rotatingblock, the other end of the fixed bracket is provided with an instrument bracket, and the instrument bracket is provided with an end face vibration detection meter and an inner circle vibration detection meter. The flywheel shell vibration detection tool can be used for detecting vibration of the end face and inner circle of a flywheel shell at the same time, and a crankshaft is used for positioning and cannot rotate, so that the vibration caused by the rotation of the crankshaft is completely avoided, and the accuracy of detecting the flywheel shell is ensured.

Description

technical field [0001] The invention belongs to the technical field of post-assembly detection of flywheel housings, and in particular relates to a tool for checking the runout of flywheel housings. Background technique [0002] In the process of engine assembly and debugging, the runout value of the flywheel housing seam is an important control parameter. The traditional method of measuring the beating value of the seam of the flywheel housing is: use the magnetic dial indicator seat to absorb on the end face of the big end of the crankshaft, press the probe of the dial indicator on the round hole surface of the seam of the flywheel housing, and rotate the crankshaft slowly and continuously for one circle , so as to obtain the measured value. This measurement method is to fix the position of the inspection tool and the crankshaft, the crankshaft rotates, the inspection tool and the crankshaft rotate synchronously, and measure the end surface or inner circle runout of the f...

AI Technical Summary

Problems solved by technology

This measurement method is to fix the position of the inspection tool and the crankshaft, the crankshaft rotates, the inspection tool and the crankshaft rotate synchronously, and measure the end surface or inner circle runout of the flywheel shell, but the inspection tool and the hole shaft of the crankshaft have a gap, and there is a gap, and the crankshaft rotates During the process, the crankshaft itself shakes, which will affect the detection accuracy of the inspection tool
