A suspension glue cushion detection tool provided by the present invention comprises a pedestal, a first sliding rail fixed on the pedestal, an upper cover positioning assembly and a rotating disc. The upper cover positioning assembly is in linkage connection with the rotating disc, when being detected, a suspension glue cushion is placed on the pedestal, by swinging a rotating rod on the rotatingdisc and on the condition that a suspension glue cushion sample is stressed, a displacement pointer used for indicating the displacement amount of a positioning plate in the upper cover positioning assembly moves synchronously with a force pointer used for indicating the acting forces in the rotating disc at the same time, the scale change values on a displacement dial and a force dial are obtained, thereby calculating the rigidity value of the suspension glue cushion. Compared with the prior art, the suspension glue cushion detection tool not only can detect the installation position precision of the suspension glue cushion, at the same time, but also can detect the rigidity performance of the suspension glue cushion, thereby improving the functionality and the universality of the detection tool.
