Cylinder leak detection tool

The utility model relates to a cylinder body leak detection tool which comprises a tool bottom plate, a plurality of limiting blocks matched with fixing blocks of a to-be-detected cylinder body are connected to the tool bottom plate in a threaded mode, two rotating oil cylinders are connected to the tool bottom plate, pressing arms are connected to the two rotating oil cylinders, top pressing plates are connected to the two pressing arms, and the top pressing plates are connected to the top pressing plates. And two sealing plugs corresponding to through holes in the top of the cylinder body to be tested are connected below the two top pressing plates. The device has the effect that the multiple through holes of the to-be-detected cylinder body are blocked while the to-be-detected cylinder body is clamped and fixed. 本申请涉及一种缸体测漏工装，其包括工装底板，所述工装底板上螺纹连接有多个与待测缸体的固定块相配合的限位块，所述工装底板上连接有两个旋转油缸，两个所述旋转油缸上均连接有压紧臂，两个所述压紧臂上均连接有顶部压板，两个所述顶部压板下均连接有两个与待测缸体顶部通孔相对应的密封堵头。本申请具有便于在夹持固定待测缸体的同时对待测缸体的多个通孔进行封堵的效果。
