背景技术Background technique

检测等径内孔筒体材料是否存在砂眼，一般采用的方法为气密性试验检测。现有技术中，使用的气密性检测工装包括两个堵头，堵头分别密封在待检测筒体的两端，然后向筒体内注压。在筒体外部将两个堵头固定，避免在气压力作用下堵头被弹出。该种工装采用外部固定，结构复杂，并且固定可靠性差，影响试验的效率。To detect whether there are trachoma in the material of the equal-diameter inner hole cylinder, the method generally adopted is the air tightness test. In the prior art, the air tightness testing tool used includes two plugs, which are respectively sealed at both ends of the cylinder to be tested, and then injected into the cylinder. Fix the two plugs on the outside of the cylinder to prevent the plugs from being ejected under the action of air pressure. This kind of tooling adopts external fixing, the structure is complex, and the fixing reliability is poor, which affects the efficiency of the test.

发明内容Contents of the invention

本发明的目的为：提供一种结构简单、固定可靠性强的等内径筒体气密性试验工装。The object of the present invention is to provide an air tightness test tool for cylinders with equal inner diameters, which has a simple structure and strong fixing reliability.

本发明的技术方案为：一种等内径筒体气密性试验工装，其特征为：所述的工装包括堵头和连接杆，堵头密封安装在待检测筒体的两端，堵头之间通过连接杆连接在一起，连接杆位于筒体内。The technical solution of the present invention is: an air tightness test tool for cylinders with equal inner diameters, which is characterized in that: the tool includes plugs and connecting rods, and the plugs are sealed and installed at both ends of the cylinder to be tested. The rooms are connected together by connecting rods, which are located in the barrel.

作为本技术方案的一种改进，连接杆为一端带有螺纹的螺杆，螺杆与其中一个堵头为一体化结构，另一个堵头内侧开有螺孔。该技术方案简化了零件个数，便于试验工况下的安装。As an improvement of the technical solution, the connecting rod is a threaded screw at one end, the screw and one of the plugs are an integral structure, and a screw hole is opened inside the other plug. The technical solution simplifies the number of parts and facilitates installation under test working conditions.

作为本技术方案的一种改进，其中一个堵头为进气阀门。该技术方案同时解决了气密性试验加压的技术问题，实现了一个工装多种用途。As an improvement of the technical solution, one of the plugs is an intake valve. The technical solution simultaneously solves the technical problem of pressurizing the airtightness test, and realizes multiple purposes of one tooling.

本发明的有益效果：该技术方案结构简单，在被试验件的内部实现了两个堵头的连接固定，避免了在试验件外部使用复杂的固定装置，与现有技术相比简化了工装结构，操作简便，缩短了试验时间。同时，用连接杆的拉力克服气体压强，与现有技术相比固定的可靠性更高。Beneficial effects of the present invention: the technical scheme is simple in structure, realizes the connection and fixation of two plugs inside the test piece, avoids the use of complicated fixing devices outside the test piece, and simplifies the tooling structure compared with the prior art , easy to operate and shorten the test time. At the same time, the tension of the connecting rod is used to overcome the gas pressure, and the fixing reliability is higher than that of the prior art.
