Heat shield testing fixture

Abstract

A clamping mechanism comprises a connecting plate, a rotating groove is formed in the upper end of one side of the surface of the connecting plate, a rotating frame is rotationally connected to the middle of the inner wall of the connecting plate, a rotating plate is rotationally connected to the inner wall of the rotating frame, and a plurality of guide grooves are formed in the surface of the rotating plate. The length directions of the multiple guide grooves all face the circle center of the rotating groove, pushing grooves are formed in the positions, close to the guide grooves, of the surface of the rotating plate, the length directions of the pushing grooves are not consistent with the length directions of the adjacent guide grooves, and the inner wall of each pushing groove is slidably connected with a clamping rod. One end of the clamping rod penetrates out of the guide groove, the outer wall of the clamping rod is slidably connected with the inner side of the guide groove, the end of the clamping rod extends out of the surface of the connecting plate, a worm on the side edge of the connecting plate is rotated to drive a worm gear to rotate, and a push groove in the surface of a rotating plate extrudes the clamping rod to move in the guide groove. And therefore, the heat insulation plates with different side edge widths can be clamped and fixed.
