Jig Device for Testing Dynamic Characteristics of Automotive Bush Insulators

摘要

The present invention relates to a jig device for testing a bush-type insulator dynamic characteristics of an automobile, comprising: a worm 18 fixed to one side of a main support 17 and fixed to one end thereof with a handle 21; A worm wheel 20 engaged with the worm 18 and rotating; A rope pulley 25 fixed to one side of the worm wheel 20; A ring support 12 fixed to an end of the main support 17 and having a fastening hole 11 for fixing to a bed of the anti-vibration rubber tester; An outer ring (6) fixed to an upper portion of the ring support (12); An inner ring 10 fixed to the inner side of the outer ring 6 and an insulator 22 fixed to the inner side; A lateral load loading jig 13 having one end connected by the insulator 22 and the inner pipe 23; A wire rope 14 having one end fixed to the rope pulley 25 and wound at the other end thereof connected to the lateral load loading jig 13; A load gauge 15 connected to an intermediate portion of the wire rope 14; The connecting hole 3 is fixed to the lower end of the hydraulic oscillator rod 1 and the inner pipe 23 is inserted, and includes a vertical load loading jig 2 formed at the lower end.;The present invention has the advantage of improving the accuracy of the dynamic characteristics test of the insulator by applying the static load accurately, and it is very easy to mount and invert the insulator and to mount the insulator of various diameters. Therefore, there is an advantage to greatly improve the work convenience and the efficiency of the jig.
