JIG FOR TESTING DYNAMIC CHARACTERISTIC OF SANDWICH TYPE INSULATOR

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig apparatus for testing sandwich-type insulator dynamic characteristics of an automobile. A support 4 having a fastening hole 4-4 for fastening to the bed of the testing machine, a worm gear 5 which is condensed by reattaching the bearing 11 to the support A 4-1 of the support 4; , A worm 6 fixed to the support portion B (4-2) of the support 4 via the bearing 12 so as to engage the worm gear 5, and a handle fixed to the shaft end of the worm 6; (10), a rope pulley (7) fixed on one side of the worm gear (5) to rotate the same axis, and an insulator (13) and a bolt (fixed to the support part (C-3-3) of the support (4) 13-1) one side lateral loading loading kit (3-1), and the other side loading loading kit (3-1) and the other side load loading connected by wire rope (8-1), (8-2) Brekit (3-2), Wire rope 8-3 having one end fixed to the rope pulley 7 and having the other end connected to the other side lateral load loading kit 3-2, and connected to the middle of the wire rope 8-3. It consists of a load gauge 9 to be connected, and a connection hole 2-1 for connecting to the bolt 13-1 and a connector 2 fixed to the lower end of the hydraulic oscillator rod 1.;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 change the orientation of the insulator, so that the work convenience and jig efficiency This has the advantage of greatly improving.
