Description

Technical Field

[0001] The utility model belongs to the technical field of shell testing, and in particular relates to a leakage testing fixture for a cylinder interface shell. Background Art

[0002] The cylinder interface housing, that is, the housing where the cylinder connector or the interface part of the cylinder is located, is an important component in the cylinder system. The cylinder interface housing leakage test is an important test method for detecting whether there is a leak in the cylinder interface housing. This test usually uses the principle of the pressure reduction method, by filling the cylinder interface housing with a fixed pressure of gas, and detecting whether the internal pressure is stable after a certain period of time, so as to determine whether there is a leak. In the leakage detection, the cylinder interface housing is clamped and fixed on the test bench, but when the existing cylinder interface housing is placed on the test bench, the position of the cylinder interface housing needs to be repeatedly adjusted to ensure that the cylinder interface housing is placed in place, which reduces the test efficiency, and repeated manual testing may also result in position deviations, thereby affecting subsequent test results. Summary of the invention

[0003] The utility model aims to provide a technical solution for a leakage test fixture for a cylinder interface housing in view of the deficiencies in the prior art. The design is ingenious and reasonable. A positioning block is used to assist in positioning the cylinder interface housing on a detection seat. The positioning block is divided into a vertically distributed positioning block one and a positioning block two. The positioning is assisted from two sides at the same time, so that precise positioning of the cylinder interface housing on the detection seat can be achieved, which facilitates the rapid placement of the cylinder interface housing on the detection seat, improves test efficiency, and is also conducive to improving the accuracy of subsequent tests.

[0006] Furthermore, a positioning groove is provided on the detection seat, a positioning boss is provided in the positioning groove, a positioning column is provided on the positioning boss, the bottom limit of the cylinder interface shell is clamped on the positioning boss, and the positioning column limit is inserted in the central cavity hole at the bottom of the cylinder interface shell. Through the combined design of the positioning boss and the positioning column, the positioning of the cylinder interface shell on the detection seat can be further assisted, the positioning accuracy can be improved, and the horizontal free sliding of the cylinder interface shell on the detection seat can be effectively restricted. The reliability is high, which is convenient for the subsequent horizontal sealing assembly and the vertical sealing assembly to tightly seal the horizontal interface and vertical interface of the cylinder interface shell, thereby improving the accuracy of the test results.

[0007] Furthermore, a sealing ring is provided in the positioning groove and is arranged on the outer side of the positioning boss. After the cylinder interface housing is pressed onto the detection seat by the vertical sealing assembly, the sealing ring is squeezed and contacted with the cylinder interface housing, effectively preventing gas leakage from the gap between the positioning groove and the cylinder interface housing, greatly improving the sealing performance of the test and ensuring the accuracy of the test results.
